REPORT 106 No surprises in the package The BSRIA report on Room and packaged Air Conditioning in the UAE reiterates the reality we have now come to accept – the economy is recovering slowly, with the results percolating down to the air conditioning sector, but it would be unwise to expect big surprises. The outlook for room and packaged air conditioning for 2014 reflects this. The long-term trend is towards splits, the report predicts.

hile the world is heartened by the progress made on the ozone front – recent images have revealed the dreaded hole as shrinking – the fight against global warming seems to be a long-drawn-out affair. According to an AFP report, quoting the National Oceanic and Atmospheric Administration (NOAA) in the United States, this year saw the hottest September for globally averaged temperature over land and ocean surfaces since recordkeeping began in 1880. While a debate is on about the possible causes of the warming of the globe – whether it is a natural phenomenon or is manmade – the broader sentiment has treated the argument as a subtext and called for sustained action to mitigate the situation. When it comes to mitigation efforts, perhaps one of the most formidable challenges confronting regional and global policy makers and planners is the need to balance social development projects and economic growth with environmental considerations. In the GCC, the talk is of affordable housing projects on one side and a vast portfolio of superstructures on the other, to bolster tourism-related revenues and other economicgrowth drivers. Housing is an urgently felt need in the region that is seeing a surge in population figures and urbanisation. According to the World Urbanisation Prospects report published by the UN Department of Economic and Social Affairs, Saudi Arabia, the UAE, Qatar, Bahrain, Kuwait and Oman will have dense urban conglomerations, with 45.1 million people expected to reside in GCC cities by 2020 – 85% of the total estimated population. The compelling statistics prevent the possibility of taking the foot off the pedal with regard to development projects, but there certainly are aspects that are more manageable, more controllable. Globally, one-third of all GHG emissions are from buildings. Also, buildings account for 40% of global energy use and 60% of the world’s electricity. However, the building industry can massively contribute towards efforts to shave greenhouse gas (GHG) emissions. The Green Building movement, with its core ideal of a cross-disciplinary integrated approach to raising structures, has shown the way, but the befuddling number of green building standards is clearly stymieing the movement’s efforts. It is a fact that too much of energy and time is expended on understanding the intricacies of the different systems, including unclear policies and stakeholder responsibilities, when it could be used to tackle challenges related to measurement of performance or the accuracy of data, to name two.

rates dropped by two per cent and three per cent respectively against Q2 figures, with sales prices also showing a nominal decline at one per cent and four per cent respectively, although year-on-year growth remained positive overall with a 31% and 17% increase in sales prices for apartments and villas. Office leasing, said Asteco, registered zero growth in Q3 following a nominal two per cent growth figure in Q2 2014. Marginal decreases were also reportedly seen in Business Bay following the earlier 2014 release of new inventory. Attributing another reason for the downward trend, John Stevens, Managing Director, Asteco, said, “The impact of mortgage cap and higher transaction fees is also making it more expensive for prospective buyers to get onto the Dubai property ladder. Describing the scenario as “wait-and-see” on the part of buyers, Stevens said he believed the sales prices could soften further with more new supply on the way.

In the short term, a price reduction would be beneficial for the market, he explained, as it would help unlock demand from the middle income segments of the population. On a positive note, the report highlighted the launch of 27 new projects during the recently held Cityscape Global, generating “strong levels” of investor interest.
Alan Thomson, Managing Director of the event partner for WWME, Abu Dhabi Sewerage Services Company (ADSSC). “POWER-GEN Middle East (PGME) Conference and Exhibition returned to Abu Dhabi after an acknowledgement of the local commitment towards working to enhance the stability and sustainability of the region’s power supply,” said Nigel Blackaby, Event Director of PGME. “The calibre of exhibitors and speakers at this year’s event demonstrates that Abu Dhabi is truly a hub for thought leadership in the power industry.”

Dhabi Education Council, and wiring regulations were recently published allowing private property owners to generate their own electricity through solar power, the announcement added. These installations are reportedly set to allow customers to meet their own power needs and supply any excess electricity generated back into the broader grid. In this regard, Nick Carter, Director General of the Bureau, said: “Together with our sector partners, we have been studying 11 sites around the city of Abu Dhabi with an installed capacity of over 2 MW which have been producing electricity for over a year, using several different panels.” The results of these small-scale solar power installations have been encouraging, and the Bureau expects to see property owners across the Emirate wishing to install their own PV panels on their roofs in the next few years, Carter claimed. To facilitate this, the Bureau has reportedly established a regulatory framework with the two distribution companies – Abu Dhabi Distribution Company (ADDC) and Al Ain Distribution Company (AADC) – to allow for the private installation and generation of electricity using PV. The framework is said to include a special Self-
Regulating Licence and an inspection programme for all would-be self-generators. “By identifying and implementing solutions that address the growing demand for energy alongside highlighting the need to conserve our water and electricity supplies through a change in consumption behaviour, the sector is making real progress to ensure sustainable resources for future generations,” Carter stated. Licensing The generation of electricity is a regulated activity that needs to be licensed by the Bureau. The Bureau’s licensing requirements are as follows: A home or small system would generally be issued a Self-Regulating Licence. The application is about two pages, cost is about AED 500 and the process may take around two months. Within the process, there is a mandatory period of 28 days, during which the Bureau will issue a public notification to allow for objections, just like for bigger generation facilities who apply. For larger systems, a Small-scale Licence, Self-supply Licence or Major Licence would apply.

he District Cooling market size in terms of value is projected to reach $29.0 billion by 2019, at a CAGR of 11.4% from 2014 to 2019, according to a report released by MarketsandMarkets, a US-based market research and consulting company. Announcing the release of the report entitled “District Cooling Market by Application (Commercial, Residential, Industrial, and Others) – Global Trends & Forecasts to 2019”, MarketsandMarkets explained that the report defines and segments the District Cooling market with an analysis and forecast of the market size by volume and value, covering the District Cooling market and its trends in the Americas, Europe, the Middle East & Africa (MEA) and Asia-Pacific. The District Cooling market is mainly driven by high efficiency of technology resulting in enhanced reliability, less water and energy usage, reduction in environmental degradation, efficient use of energy and reduction in strain on a nation’s electricity grid, the report elaborated. Issues, such as inaccurate estimation of cooling demand and incoherent cost recovery (protection, isolation, labelling, etc.) listed in the Electricity Wiring Regulations. Evidence of material compliance to the Regulations (PV modules, inverters, balance of systems, etc.) shall be submitted to the distribution companies for approval. The AADC and ADDC are working on a list of pre-approved equipment. The customer needs to engage with a registered solar PV integrator, as only a licensed contractor may work on Electrical Installations. Lists of approved solar PV
models are the after-effects observed in the District Cooling market that needs to be addressed to boost the market, the report highlighted. High upfront capital cost and nonsynchronised development, the report said, were the major restraints in recent years, it added. In what could be viewed as a boost to the District Cooling sector in the region, the report revealed that the MEA region is the fastest-growing market due to rapid growth in the real estate and commercial sectors, marked by increasing demand for power and cooling during peak hours, which could be detrimental to a nation’s power grid security. According to the report, the Asia-Pacific region is the upcoming potential market due to emerging economies, such as China and India, where a large number of infrastructure activities are lined-up. The leading players in the market reportedly include Emicool (UAE), Empower (UAE), LOGSTOR (Denmark), Ramboll (Denmark), Tabreed (UAE), Stellar Energy (US), and ADC Energy Systems LLC (UAE), along with Shinryo Corporation (Japan) and Keppel DHCS (Singapore) being the leading regional players in Asia-Pacific. integrators may be obtained from the distribution companies. A licensed contractor shall also be appointed to carry out any electrical installation work (working closely with the solar PV integrator) and to liaise with the distribution company on the submittals, drawing approvals and inspection process. The concerned distribution company will review and approve design drawings and then carry out an inspection to verify compliance with the regulations before connection is given.

KEY INSIGHTS ON WHAT'S MAKING NEWS
Tick
'Manufacturers need to agree on sharing code' In 2014, Faisal Jassim Trading Company became a part of the growing tribe of VRF suppliers in the region with a strategic tie-up with Samsung Electronics to market and distribute its VRF system. The company’s Ibrahim Anani talks to Climate Control Middle East about how the entire VRF industry needs to collaborate in convincing consultants on the multiple benefits of the technology and also on Samsung’s proprietary one-to-one system
Where has the VRF industry reached in its drive to break down the barriers of resistance among the consultant community? I feel there is still a lot of work that needs to be done. I still find owners and consultants not completely believing in the VRF technology, as opposed to chilled water systems. I agree, chilled water systems represent a good option, but there are a number of unresolved issues there, such as the capex, installation and maintenance, which are all expensive. On the bright side, I have had interactions with many consultants, who are thinking of changing to VRFs, be they for hotels or villas. At Faisal Jassim, we work with a lot of consultants from the design stage – and I see more and more projects where VRF systems are likely to be considered. Another boost for the technology is the growing industry. Most major manufacturers have their own VRF

systems, so the whole industry is pushing for the VRF technology. Speaking specifically about the Samsung VRF technology, it has many unique features. The capacity of the outdoor units is the highest in the industry. The large capacity reduces the number of condensing units on the roof or the ground. There is less piping, which means reduced installation costs. Also, the maintenance comes down. The length of piping in VRF systems in general is still of concern among developers and consultants, yes? They fear the possibility of occurrences of leakage of refrigerant is that much higher, don’t they? You have to be careful while installing the system. It is important that the principal stakeholders involve the suppliers at the design stage itself, to ascertain how many zones to have, the piping length, etc. The

ilo Middle East conducted a seminar on October 22 at Address Dubai Marina Hotel to present its solutions for building services, water management and industry.

problem is that they involve us much later. In the case of Samsung, piping is not an issue but one of our strengths. For long, consultants have been asking for operational data. What needs to be done to make it available? Events like the Annual Middle East VRF Conference are platforms to interact with peers. Manufacturers have to take the initiative to agree on a code for sharing information. When you talk to manufacturers of VRFs, they give different features – that has to change. In the case of Samsung, we are proud of the large capacity of the outdoor units. We are equally proud of the centralised control system feature, which allows us to remotely monitor and control the VRFs, even from an overseas location. We have the facility to share data with the factory, and they can advise the end-user. What is Samsung doing to penetrate the vastly promising retrofit market? We are trying retrofitting options, but it is not easy. If clients have an existing chilled water system, they won’t opt for retrofitting; that said, if they are suffering with the existing regime, they will accept the idea of having VRFs in their premises. But there is a lot going for the system. The buzz is about the new one-to-one system, where the compressor used for VRF can be used to meet the requirements of either 10% of the load or 100% of the load, thus enabling the customer to achieve a COP of 3.4. Overall, the one-to-one system gives a billing solution to residents and a high COP. It runs on the widely accepted R410A and allows the customer to achieve a specific airflow.
The participants, said Wilo, were invited to experience the water cycle from its sources, purification and distribution to collection and sewage treatment up to its return to nature. The company claimed that that it offered solutions like the Wilo-SiBoost Helix EXCEL, a pressure boosting system that combines efficient motors, hydraulics and intelligent controls, that contributes to a cleaner and more sustainable world.

ASHRAE releases Legionellosis Standard for public review draft Will establish minimum Legionellosis risk management requirements for building water systems
I
n an official communiqué, ASHRAE has announced that a fourth version of its proposed Legionellosis standard is open for public comment until November 10. Standard 188P, Legionellosis: Risk Management for Building Water Systems, currently under development, will establish minimum Legionellosis risk management requirements for building water systems, ASHRAE said. The standard, ASHRAE added, was intended for use by building owners and managers and those involved in the design, construction, installation, commissioning, operation, maintenance and service of centralised building water systems and components. According to ASHRAE, changes to the proposed standard since its last public review in January 2013 include the following: Alignment of the document with the revised title, purpose and scope. Removal of hazard analysis and critical control points (HACCP) terminology Inclusion of a normative appendix for health care facilities meeting specific requirements that provides an alternative compliance path that is more stringent than for other facilities. More emphasis on requirements for design, construction, installation, commissioning, operation, maintenance and service Tom Watson, Chair of the Standard 188P committee, explaining the need for a public review draft, said: “Building water systems vary substantially in their design and their capability for transmission of Legionella. Scientific evidence is either lacking or inconclusive in certain aspects of Legionella control. The informative guidance is included to provide suggestions, recommendations and references.” Details about actions regarding ASHRAE standards is reportedly available at www.ashrae.org/listserv where it has provided subscriptions to a variety of listserves, including one for Standard 188P, that will enable interested parties to stay up to date with the latest news, publication offerings, and various other Society activities. The draft of the document and instructions on submitting comments can be found at www.ashrae.org/publicreviews, ASHRAE said, and added that the proposed standard will be available for access until Novembter 10, 2014, ASHRAE informed.

interview JCI
“We definitely feel the economic upturn” Ashraf Abdalla, the Vice-President and General Manager of JCI for UAE and Qatar, and the Vice-President of Commercial Operations and Offerings for the Middle East Region, in conversation with B Surendar...
When it comes to chillers, how much of your focus will be on District Cooling and how much on standalone solutions, considering that the consultants’ community in the GCC region seems to be polarised on the basis of the two approaches?
I wouldn’t put it as polarising. Fundamentally, the consultant community tends to look at what is best for an application. When you have the situation we have in the GCC region, where whole cities are coming up, you have the privilege of picking up right solutions upfront as opposed to cities like London, which are already built. So it’s not an either-or situation, but customer requirements and energy profile. District Cooling has an edge over standalone from an energy-efficiency point of view. When you consider 100 buildings and District Cooling, diversity comes into play. If you have 100 standalone systems – varying from mini-splits, air cooled, watercooled – you will get a mix of efficiencies. Conversely, if you don’t have scale, the standalone approach will be the best solution. The region here probably 50
The target of 15 million tonnes of refrigeration in the GCC region is just delayed, but it is going there. This is one of the growing regions in the world. I have to change the map of my GPS every month, owing to the construction activity
Climate Control Middle East November 2014
has the highest District Cooling application in the world, mainly driven by the way cities are coming up. As JCI, we cater to both District Cooling and standalone. The chillers going to District Cooling or standalone are not a lot different, but how you get them working for District Cooling or standalone, that’s the issue. The majority of the work is pretty much the same. We have products for optimising systems to run efficiently in central cooling plants. And we have the Optisound technology for Centrifugal compressors, which has made it possible to deploy small-tonnage chillers for standalone projects.
The World Bank is reportedly considering lending financial support towards the deployment of District Cooling regimens in the developing world, including parts of the MENA region. With the nascent economic upturn and an upswing in project announcements in the UAE, Saudi Arabia and the other GCC entities, do you see a ramp-up in demand for chillers? And should the region reach
the stratospheric levels of euphoria, witnessed in the mid-noughties, when the talk was of 15 million TR of District Cooling by 2015, would you consider a chiller manufacturing base in the GCC to reduce shipment times?
We definitely feel the economic upturn. There are factors that will limit the growth to six per cent or eight per cent, but growth is happening for sure in the UAE, Qatar and Saudi Arabia, because the governments are driving growth. It’s more a matter of how much. Whether District Cooling will take market-share or not, it depends on where the projects are coming up. There are a number of district-based projects coming up in Dubai, so maybe we will see a higher penetration in Dubai. So the nature of the projects will dictate. It’s a market call. The target of 15 million tonnes of refrigeration in the GCC region is just delayed, but it is going there. This is one of the growing regions in the world. I have to change the map of my GPS every month, owing to the construction activity that is going on.
And if developing countries get funding from the World Bank, that will definitely help the District Cooling industry here. With the likes of Empower and Tabreed not only having the experience, but also leading the industry and breaking new ground, there is room for optimism. As for us establishing a manufacturing base here, our aim is to meet our customers’ increasing expectations, and we need to be ahead of them, and we need to be ready from that standpoint, and it’s always an option for us to look at manufacturing. We already have two manufacturing facilities on the air side. And we can transfer a lot of chiller designs, which are global designs. And there’s not a lot of re-engineering that needs to happen. So

Lead time is very important when construction is going up. If certain things are going to change and if chilled water systems are going to drive change, we will align to that
our manufacturing footprint is very dynamic. So why not a water-cooled chiller manufacturing base in the region? Lead time is very important when construction is going up. If certain things are going to change and if chilled water systems are going to drive change, we will align to that. We will serve the market the way it wants to be served.
In 2013, JCI announced it was going to acquire 60% ownership of Hitachi’s air conditioning business. How have plans progressed since then?
We have been progressing on the joint venture, and part of the joint venture is we have 60% share, and that’s still going through. We have been working on the joint venture
November 2014
for some time now. The decision to go ahead with the joint venture came through when we both realised there was an opportunity, where we looked at the strengths of JCI and Hitachi. There is significant synergy there, and the two companies complement each other to make it the largest HVAC company in the world. We have good global coverage, and they are strong on VRFs and also have a pretty good chiller line. There is high level of alignment between the two companies. The progress on the JV is heartening. VRF in itself is growing in a number of markets.
Is your focus increasing on the VRF business? What is JCI’s level of belief in the

interview JCI VRF technology?
I have heard VRF discussed a number of times as a new technology, but it has been around since the 1980s, so it certainly has its applications and usage. Applications drive solutions, and so I see VRF and chilled water systems coexisting. I can’t say how much is the increase in the VRF side of the business, but it is a significant increase. We already have our own VRF facility in Wuxi, China, and now with the Hitachi development, there will be a high level of collaboration, as soon as we announce the completion of the JV formation.
One of the attractions of the JV is we complement each other. We already have the VRF technology, and that will be strengthened

We already have the VRF technology, and that will be strengthened. They (Hitachi) also have a very strong absorption line, and we are seeing a market revival of the absorption technology, so it bodes well. We talk a lot about chillers, but controls also play a big role in building automation. Our offering is already broad with controls, so VRFs, chillers and controls will be
a broader offering to enhance building performance.
There is talk that JCI will be divesting its York range of solutions, apparently owing to its dwindling market share in the residential market. Is this true?
That’s categorically not true. The way we are investing in products – we acquired ADTI (grilles and diffusers) and the implications of the Hitachi JV – is a message that we are intent on enhancing our lightcommercial and commercial offerings. Chillers as a York brand continue to be very strong for us, so we will not be divesting.

In the GCC, we have had instances where end-users have been unable to use their buildings, owing to some disruption or the other, but still have received bills towards payment for the supply of chilled water to the buildings. This is causing anguish among the affected end-users, which is not favourable for the reputation of District Cooling. Have you had similar situations in St Paul? How have you responded? When it comes to our billing system, we do have capacity and energy charges intertwined, which are paid through the year by the customer base. And if we have any situations, we work through them. I don’t have the specifics of the situations you refer to in the GCC region and so cannot comment on them.
What special care do you take of your customers in St Paul?
Customers are extremely important and an overall part of the strategy in St Paul. To the extent that we have a fulltime staff that spends time interacting with customers on such issues as how the buildings are performing with regards to Delta T and how their building systems are working. The members of the staff are highly skilled energy engineers. In St Paul, 95%-99% of the meters are tied with a fibreoptic system that we can monitor, and if we see the Delta T decreasing, we can alert the building manager and enquire if they need our assistance to look into the issue. It could be as simple as doors that were not supposed to be open that are open. We handle such types of unique circumstances that arise or if service was interrupted for some reason. To us, it is a partnership with our customers.
have. Another initiative is an annual training event for customers. For this, we bring outside speakers that inform customers on how they can improve the performance of their buildings. Prior to the event, we ask what training they would like to have, so the preparation is quite detailed. We also facilitate lowinterest loans and funding mechanisms to help customers make their buildings more energy efficient.

There is not an incentive for profit. The customers on the Board ask: Are you maintaining the infrastructure responsibly? Are you giving good reliability? Are you giving good value to customers? Are you thinking about the future? One of the District Cooling providers in the region has begun offering FM services, and another is mulling over the idea. Do you have a similar approach? We have talked about whether to provide additional services, such as FM, in St Paul. We have worked with a variety of outside providers, and either through their staff or our staff, assessed the needs of customers. Our full-time customer service team is constantly trying to understand heat exchanger issues, maintenance issues, control valve issues. Our engineers have hands-on experience and often can solve issues without having to call anybody. If the customer has a design issue, then we point them to the right resources. To the extent we can help them we will.
Would you be leading any discussions on the customer side during the IDEA conference in Dubai? I have talked to Rob (IDEA President Rob Thornton) about specifically speaking about customers. You have lot of engineers in the District Energy space, and engineers tend to get enamoured of the equipment, but at the end of the day, you need to think about the customers’ perspective, what is important to them, and what we can do to meet their needs and exceed their expectations. www.climatecontrolme.com

The Goldilocks zone The German HVACR market, mirroring others the world over, has not been immune to the economic turbulences of the recent years. But thanks to being Europe’s traditional growth engine, it has managed to keep afloat. How has the manufacturing giant fared? Pratibha Umashankar reports.

oldilocks, the protagonist in the famous fairy tale, when lost in the woods, enters a bear’s lair and chooses the baby bear’s bed to rest on, as it’s neither too hard like the Papa Bear’s nor too soft like the Mama Bear’s. It’s just right. When applied to market economics, a Goldilocks economy is one that sustains moderate economic growth and low inflation, as the market is neither bullish and nor is it a bear market. Though things have not been “just right” for Germany, it has managed to be in the proverbial Goldilocks zone.“Europe’s largest economy has seen a run of lousy numbers for factory orders, industrial production, exports and business confidence,” declares David McHugh, an AP Business Writer, in an article in US News (http://www. usnews.com/news/business/articles/2014/10/10/germandownturn-casts-shadow-over-world-economy). “But are things in Germany all that bad?” he asks, and answers, “Economists are debating whether it’s really time to use the R-word and predict a shallow recession.” As Germany goes, so does Europe, he observes, and adds: “Strong business activity in Germany has made the overall growth figure for the 18 countries that use the Euro look a lot better in the past few years. And Europe showed zero growth in the second quarter. Germany is 28% of European GDP.”

Energy efficiency and innovation
As can be surmised from the above highlights, Germany lost some, won some but managed to remain afloat. The reason? “Quality is never a compromise for a German manufacturer,” states Stefan Leitl, Managing Director at Bitzer Middle East, summing it up in a single sentence.
In keeping with the global market trend, energy efficiency has been among the top HVAC market drivers in Germany. With their heightened awareness about sustainability and the longterm benefits of utilising energy-efficient systems, German customers are observed to be willing to pay for quality air conditioning systems, if only to save on lifecycle costs in the long run. “Energy efficiency is a key issue throughout the entire refrigeration industry,” says Leitl, underscoring this. He elaborates: “From 2015, new efficiency requirements for
Moving to CO2 Stefan Leitl, Managing Director at Bitzer Middle East, speaks about his company’s experience in the CO2 refrigeration systems…
“B
itzer recognised the increasing global role of natural refrigerants early on, which is why we’ve been consistently optimising our CO 2 technology for more than 15 years, and have gained experience in the use of sub- and trans-critical compressors in CO 2 refrigeration systems. And it has paid off, as the global trend is moving towards CO 2 , particularly in Germany, Scandinavia, North America and Australia. Developed to reduce the global warming potential of refrigerants, the new F-gas regulation will go into effect in Europe on January 1, 2015. With a GWP of 1, CO 2 is of course ideal. Many supermarkets have therefore already switched to the natural refrigerant, such as Bitzer’s partner Carrefour, a French retailer which uses trans-critical refrigeration systems with Bitzer compressors at 28 of its businesses. Another 53 supermarkets with corresponding systems are already in the pipeline. And in Canada, specialist in CO 2 refrigeration systems Carnot Refrigeration relies on Bitzer compressors in more than 40 of its systems.”

Climate Control Middle East November 2014
System replacement due to refrigerant bans has not yet led to a new significant area of business fans and condensing units will apply in Europe. With the introduction of this Ecodesign Directive (ErP) [Energy-related Products], the European regulations will be the strictest in the world. This, of course, will also benefit those regions in which these stringent requirements have yet to be introduced.” In Leitl’s opinion, both the ErP Directive and an increase in energy prices in Germany have been the driving forces behind innovative ideas and new solutions, such as the integrated inverter and electronics for reliable and efficient operation of compressors and systems. “Lifecycle costs (LCC),” he says, “provide end-users with greater transparency in terms of the costs for the entire service life rather than just the initial investment. Using LCC arguments in the sales pitch is a new approach and requires training. But new European regulations, such as labeling schemes help to
win over end-users and contractors.” Regulations and standards in Germany established over the years, directed by sustainable practices, have made companies come up with best practices and innovations, making it a mature ecosystem for the new F-gas regulation. “The new F-gas regulation in Europe and the Directive for ErP primarily have an impact on the HVAC[R] industry in Europe and Germany,” admits Leitl. With reference to his company, he says, “Bitzer has more than 15 years of experience with CO2 and other natural refrigerants, and as a technology leader, we’re very well positioned in the segment. Over the past five years, product development has focused entirely on achieving a low GWP and solutions based on natural refrigerants.” (Also see Box: Moving to CO2)
Regarding energy efficiency in the context of retrofits, Leitl believes that a significant increase in building renovations has been observed in Germany, and that owners are opting for renewable energies and the use of heat pumps primarily in redevelopment projects. “In the area of existing buildings in particular, there’s still plenty of potential for retrofitting,” he says, but adds, “System replacement due to refrigerant bans has not yet led to a new significant area of business.”
Closer home
Saudi Arabia and Qatar, as if by a default setting, are the two names that pop up in any discussion on the regional market. The HVACR
sector is no exception, with manufacturers and suppliers the world over, Germany included, vying for a piece of the Saudi housing and the Qatar World Cup 2022 pie. Leitl concedes that the industry is much more competitive now than it was before, with Saudi Arabia being a much bigger market compared to the other GCC markets and companies. “But it doesn’t mean that SaudiArabia and Qatar are the main focus,” he cautions. “It is equally important to find new market opportunities for maintaining consistent growth.” He adds, “It’s important to remember that different markets have very different requirements, whether they’re based on climate or special
authorisation criteria.” The UAE is once again beginning to be seen as the regional hub, and German companies like Bitzer have responded to this. “We launched the Green Point UAE service centre during the BIG 5 trade fair in 2012 [in Dubai],” says Leitl. “Since then, we’ve been providing our customers with maintenance and repair services as well as training courses there. We also invest a great deal in training in Germany: the new Schaufler Academy training centre in Rottenburg-Ergenzingen represents yet another milestone in the area of customer training and will make a valuable contribution here.” On what can be termed a
November 2014
heartening note, Leitl says that the HVACR sector is one of the least affected industries. “When we consider the construction industry, our piece of the pie is not that big,” he explains. “But for the refrigeration industry, we do not expect any drastic downturn, since it is an unavoidable part of the food industry.” Shifting the gaze to the R of the HVACR, is perhaps a sound strategy Bitzer has adopted, which might be worth emulating, as the construction sector in the region could still be volatile, but the food market, and by extension the refrigeration sector, holds greater promise, not only for Germany but also for other countries.

ngineering Consortium Consulting Engineers (ECCE) has its roots in the UAE (Abu Dhabi, Dubai and Umm Al Quwain), but Dr Marcus G George, the man at the helm, has spread his vast experience from the UAE to Qatar and from India to Kenya, and also to Turkey, with his partners. “I have always had a vision to become an international figure, and I’m delighted at having achieved it,” says Dr George, who is the CEO/ Partner of the local and international companies.
Far pavilions
Over the years, ECCE has built a strong track-record of successfully completing design assignments related to architectural engineering, structural engineering and electromechanical engineering, a result of the hard efforts of Dr George and his team in Dubai. At the beginning of this year, Dr George decided that the next step was to become a truly international figure, and took resolute steps to achieve that. “Apart from offices in Qatar, Dubai and Abu Dhabi, my partners and I opened an office in Pune, India, which is handling supporting engineering work,” says Dr George, his gaze trained towards distant horizons. Mr Malhotra is the Managing Director and Partner of ECCEEVOM (see side-bar, titled ‘Turning to the sun’). Called Global Design Engineers, the Pune office is designated to do pure engineering drawings – essentially detailed architectural, structural and electromechanical work. “The Pune office,” Dr George explains, “will work on projects the company acquires from around the world, and complete the concept designs.” Subsequently, Dr George and Mr Malhotra also

To date, ECCE Dubai has managed to bag five big international design projects – in Afghanistan, Saudi Arabia, Baghdad, Lebanon, India and, of course, Nairobi – worth billions of dollars. “And the Borooq City project in Qatar alone is worth two billion euros,” says Dr George. As part of the international expansion plans, ECCE Dubai and AEC are establishing a free-zone company in Mauritius. The momentum is building well in Turkey. And in the UAE, the expansion is on overdrive. “Soon, ECCE Dubai will have a massive presence in Umm Al Quwain,” Dr George reveals with the astuteness of a military

The first part of the project is worth AED 60 million.” Expansion, to ECCE, apparently, is not only a geographical one. The company has grown in terms of human resources, with 100 onsite engineers for all its projects, and 90 design engineers working at the drawing boards.
Green in the DNA
Also, growth is not just outward but also inward. “Our philosophy,” explains Dr George, “is to align ourselves to the region’s laudable sustainable development goals.” He believes that today, the path to success has to traverse via the energy-efficiency route. Likewise, it is important to conserve water to the maximum. “We recognise and acknowledge the twin 66

needs and have woven it into our collective psyche as architectural, structural and electromechanical engineers,” he says. “All our electromechanical engineers have vast exposure to the latest in sustainable development initiatives and also the regulations and specifications. We send them to cuttingedge courses, so they are on par with the best in terms of skills-sets. Their knowledge base is finely tuned to green
Climate Control Middle East November 2014
initiatives, and they have the right instincts and the courage of their convictions to ensure energy and water savings in all the projects we design.” Dr George enumerates his company’s green credentials, with the Nakheel headquarters green building in Jebel Ali being one of its marquee projects. In Abu Dhabi, the company is poised to design a green building project for the Abu Dhabi Municipality. “Green is in our DNA,” Dr George claims. “And we draw
from our heritage, be it when it comes to selecting building materials at the structural phase, which includes the right type of insulation before cladding works, or when it comes to electro-mechanical engineering.” Since the company provides turnkey solutions, which is a combination of architectural, structural and electromechanical disciplines, it is able to harmonise and optimise all the phases of the construction, believes Dr George. “The end-product is a perfect fit with the surroundings, with no engineering compromises – it’s value engineering at its very best,” he underscores. Constant vigilance, perseverance and going into micro-details, be it passive cooling or green roofs, is the exacting price extracted by the environment, Dr George concedes. “To ensure we conserve water, we divert condensate water from rooftop air conditioning units to water the green roofs,” he cites, as an example of the company’s green vision. He elaborates: “Leaders the world over are concerned about desertification, so it’s essential to green the world. Many years ago, the UAE took bold steps under the

Today, looking out of my office window, I’m astonished by the greenery I see in every square mile.”
Value engineering
Many valuable lessons have been learnt by individual organisations and the GCC states collectively in the last decade alone, through a demanding process of trial and error. ECCE believes it is no exception, and has striven to fashion for itself what it believes are the best of engineering practices. “The shift in engineering thinking that happened in the mid-noughties of this century ought not to be taken as an example,” Dr George warns. “We saw buildings coming up that disregarded engineering practices. The precursor to that was the frenzied thinking and greedy November 2014
design-and-build assignments. Several companies sought to bite more than they could chew. As a company, we are extremely mindful of the perils of hurrying through projects. Our fundamental approach is to design and build structures – be they schools, commercial towers or malls – in a manner that benefits the economy of the region.” That, he believes, can be achieved through energy and water conservation. Engineers at ECCE, says Dr George, strictly adhere to regional and international standards, which include not only energy and water efficiency, but also Indoor Environmental Quality. “Our engineers do not merely internalise these socioeconomic ideals but also go to great lengths to convince our clients to adopt value engineering and green thinking.” This, he says, includes doing one’s utmost to shape consensus among all the stakeholders involved in a building – that any additional capex is not a burden but a strategy to ensure the building runs economically and is environmentally friendly in the long run. “It is essential that we breathe value engineering into all our projects,” Dr George says. “We aspire to ensure integrity in everything we do, and that’s part of the collective psyche of our team.” www.climatecontrolme.com

The fan coil unit market in Europe, Middle East and Africa region (EMEA) region has sales of some 1.45 million units – equal to 2012. As in previous years, European sales represent approximately three-quarters of the market. Within the European Union, Italy is still ahead of the pack with a quarter of all sales, followed by France, with a 14% market share. Sales in Germany and the UK have remained modest, each with a market share of approximately five per cent. Outside of the EU, it is Turkey which stands out with its continued steady growth and a market share close to 10% this year against seven per cent the previous year, thus leaving Russia behind, with seven per cent of sales in the EMEA region. The Middle East retains its place as the second largest player in the EMEA region, with approximately 260,000 units sold in 2013. Compared to 2012, Italy continues its decline with a contraction of about 10%. Conversely, the Turkish market is still in full expansion, showing a record growth of almost 30%. Changes occurred this year for Spain and Portugal, which recorded respective rises of eight per cent and three per cent. However, Poland and 68
Outside of the EU, it is Turkey which stands out with its continued steady growth the Northern countries have dropped to -10%, and Russia experienced a sharp decline of minus four per cent after two years of growth. From a technological viewpoint, changes are minimal. The two-pipe fan

coil units still represent three-quarters of the market, except in Turkey and the Benelux countries, where the ratios are the same. On the design side of things, fan coils with casing and without casing each represent 30% of the market. The remaining market is split in equal parts between cassette-type models and ducted-type models. In terms of forecast, the year 2014 should achieve the same level as 2013 in the EMEA region, with perhaps some slight growth of around 1.5%. The forecasts remain positive for already dynamic areas like Russia and Spain. However, they are gloomy for Italy, which began the year with
falls varying from minus three to -10%.
Rooftops – market still dominated by the Middle East
The rooftops market in the EMEA region amounts to about 60,000 units sold in 2013 – five per cent more than the previous year. The Middle East is still leading the way with more than 80% of the market share, with Africa coming a distant second with 4.2%. Within Europe, the market distribution is more even. Ahead of the pack is the France-Spain duo with market shares nearing 20%. Then come Turkey, the UK and Italy, with approximately 10% each. The rooftops market remains dynamic, with considerable 2012-2013 growth and upward 2014 forecasts. Contrary to previous years, it is in Europe that the highest growth rates have been recorded, particularly the UK recording +30% and Spain and Turkey with increases of up to +20%. As for France, growth is visible but subdued with a four per cent increase. By contrast, the market has experienced a serious setback in Italy with a drop of approximately -15%. In general, the most sold rooftop unit-types in the EMEA region are the medium-capacity units of between 17 and 72 kW, representing approximately two-thirds of total sales. The small-capacity units of under 30 kW are on the rise in the Middle East, but it is the units of over 30 kW, which remain the most sold in the rest of the EMEA region. In terms of technology and given the very high temperatures of the region, cooling units were sold exclusively in the Middle East alone. Conversely, nine tenths of units sold in Europe and Africa were reversible models (classic and gas models).

Chillers – Turkey continues to affirm dynamism
The chillers market in the EMEA region grew, reaching 20 millions of kW in 2013 against 17 million in 2012. The largest market was the Middle East with 18% followed by Germany (15%), France (14%) and Italy (12%). In the small-capacity category of under 50 kW, the sales were concentrated in the South of Europe. Italy’s market share reached 45%, followed by France with 13%. Germany had a respectable market share nearing nine per cent. For medium-power machines, the leading trio were Italy, France and Germany, with respective market shares of 16%, 14% and 10%, which accounted for almost half of the total European market. The Benelux countries, the Nordic countries, the UK and Spain fluctuated around six per cent. Conversely, for highpower machines (above 700kW) it is the Middle East which has led the way with 25% of the market share. Coming in second position were Turkey and Russia with eight per cent of the market followed by France, Germany and Italy, with respective market shares ranging from
six to 7.5%. Compared to 2012, there was a market stagnation for machines of over 50kW in the EMEA region. This is balanced primarily thanks to the significant increases in Scandinavia and Turkey, which respectively reached 14% and eight per cent, thus mitigating the negative trends in other countries. In the European Union, the year has been less than buoyant. The fall has been most significant for the UK-Ireland duo with minus nine per cent, followed by France with minus six

per cent. Furthermore, the number of chillers has also fallen in Africa, primarily due to South Africa recording more than 20% fall between 2012 and 2013 due to social conflicts slowing market growth. Over three-quarters of chillers sold in the EMEA region are air-cooled not water-cooled. In terms of refrigerants, it is the R410A, which is comfortably in the lead, used in 80% of all units. The R134A comes next with 14%.
A sluggish year for CRACs
Of the approximately 30,000 Computer Room AirConditioner (CRAC) units sold in 2013, over 25,000 were sold in Europe. In the EMEA region, the market leader remains Germany, with 12.5% of the market share, followed closely by the UK with 11%. Russia and CIS countries continue to hold third place with 10.5%. As for the Middle East and Africa, their respective shares are 9.5% and 6.5%. The CRAC market had a weak year in 2013 in the EMEA region, almost stagnating around 0.5%. Within the European Union, the market declined 70
Climate Control Middle East November 2014
sharply, with drops of up to -20%, with France, the Benelux countries and Spain suffering the most with drops ranging from -16% to -20%. Germany was also affected with recording minus six per cent. The same goes for UK and Ireland with minus four per cent. Only Italy and the Scandinavian countries saw their market shares grow by 10%. The EMEA region, the Middle East and Africa recorded the highest increases with approximately +30%, followed by Turkey and the Austria-Switzerland duo with plus eight per cent and Eastern Europe with plus three per cent. Two-thirds of the units sold in the EMEA region were direct expansion units, and the remaining third were chillers.
AHUs – fewer players
The AHU market fared relatively well, with a rise of 2.8% in 2012-2013 in the European Union, and an increase of over 10% in the Middle East. The main driver behind this rise was Germany, with a total of nearly 20% of all sales and an annual growth rate of +10%. Although the other heavyweight in the region, Scandinavia, with 15% market share saw its sales stagnate, substantial progress was again made by Russia and Turkey, which respectively recorded +17% and +46%, between them, totalling over 13% of the market in 2013. To a lesser extent, Spain and the Czech Republic have seen an increase of eight per cent, respectively. Italy underwent a small market contraction and Portugal saw a fall of 20%. With regards to airflow power, units of under 5000m3/hr continued to be the most sold with 52% of the market share in the EMEA region against only 6.3% for units of over 30,000 m3/hr. The market also witnessed a
reduction in the number of players, with a few small ones disappearing or being taken over by larger ones.
Not many takers for air filters
The air filters market saw a contraction of 0.7% in the European Union and almost stagnated at -0.4% in the rest of the EMEA region. This could possibly be either due to the extended life of the filters in place or the increasing external supplies, such as China or India. Germany, the biggest market in 2013, grew moderately by about four per cent, while France, the second largest player, saw its market stagnate. The Scandinavian countries, which represent between them approximately 15% of the EMEA region, saw their market decrease by about five per cent, as did Switzerland, while Italy and Spain saw their sales increase by six per cent for the first quarter and over 15% for the second. Among the products most sold in the EMEA region, the market share of fine and medium filters continued to increase, achieving 60% of the market in 2013. Next in line were the coarse filters with 19% and the HEPA-ULPA filters with 16%. Gas-phase filters barely represented five per cent of sales.
2013, much more open- than closed-cooling towers were sold in a ratio nearing 65:35.
A good year for heat exchangers
The heat exchangers market increased by approximately 15% more than in 2012. Aside from Germany with its 17% market share, the main players were Russia and Italy. Leading the way with highest growth were the Benelux countries, Russia, the Middle East and the Scandinavian countries, recording rises over 20%. Conversely, Italy experienced a small contraction in its market share.
Adiabatic coolers – an emerging market For some years now, we have increasingly been seeing the comeback of adiabatic
coolers, which consists, in the context of heat exchangers, of facilitating heat exchange between ambient air and liquid to be cooled by increasing the degree of humidity in the surrounding air. This can be done using nozzles which spray water directly onto the batteries, or through a permeable media positioned in close proximity, and which is humidified (water which is used for humidifying may be recuperated or not). Above all, it is a backup used temporarily when the summers become too hot. This is why the technology is still barely used in the North of Europe and is absent in the Middle East. Its main markets are currently in countries with temperate climates like Germany, France, Switzerland and Eastern Europe.
Cooling towers – a declining European market
The cooling towers market experienced a contraction of around seven percent in the EMEA region. Topping the sales charts was Germany, followed by Russia and CIS countries. Italy, France and the UK were secondary players with eight per cent of the market each. Among those with the greatest growth were Russia and Poland. Those with the largest declines were France and the UK brushing the -20% mark. In the EMEA market in November 2014

lass-clad towers have risen rapidly all over the region, symbolising opulence and urban development. More the buildings, more the glass being used. It’s indeed a sector that’s making hay while the Middle East sun shines. Derek Burston, Exhibition Director, GulfSol, calls glass “big business” in the region and supports his claim with statistics: • In the UAE alone, Glass LLC – the corporate arm of Dubai Investments PJSC – runs four wholly owned subsidiaries that represent a combined capital of AED 400 million and investments of AED 1.1 billion. Each company – Emirates Float Glass, Emirates Glass, Lumiglass Industries and the Saudi American Glass Company – supply to the construction industry, and each have reported positive growth, which has surpassed expectations. • The UAE’s glass industry is bracing for an unprecedented growth, as the country’s construction industry is poised to witness a compounded annual growth rate of around 20% from 2010 to 2013, with approximately 1,300 projects worth over USD 418 billion currently under construction across the UAE. • A 2013 study by MEED Projects, has reported that several construction and infrastructure projects have been awarded to the GCC countries, which include: USD 119 billion to Saudi Arabia, USD 75 billion to the UAE, USD 26 billion to Qatar, USD 30 billion to Oman, USD 25 billion to Kuwait and USD10 billion to Bahrain. • NanoMarkets estimates that the total global market for
smart mirror technologies was approximately USD one billion in 2013, and that it would grow to a value of USD 3.4 billion by the end of the decade. • As the Middle East has the human resources and sand, companies operating in the region find it is easy to manufacture and export glass to anywhere in the world. “There’s rapid growth in sales of energy-efficient products, such as solar control, insulation and low-E glass,” says Burston. “The solar energy market, which was hurt by recent global economic weaknesses, will take off briskly once again,” he predicts but adds that demand for flat glass used in solar energy applications is a

niche market. Calling modern-day glass towers monuments to architectural excellence and proof of huge advancements in engineering and manufacturing capabilities, Burston says: “Glass has transformed the way in which the world builds and lives. Glass has not only made it possible to reach unimaginable heights, but it has also given us the chance to enjoy the view.”
Is the glass half empty?
Burston’s view is not without its detractors. In his article, titled “Can Highly Glazed Building Façades Be Green?” John Straube points out that glass structures require a lot of heating and cooling just to maintain comfort levels. He
November 2014
tries to explode the myth that glass-enveloped buildings are by default green. The conundrum is inescapable. The solar heat gain necessitates air conditioning, and the size of a building’s air conditioning plant defines the glazed area. More the glazing, the more the need for extra chillers, ducts, coils and fans.
Glazing out of the window
This brings us to the niggling issue of glazing. “It is a testament to the miracles of modern glazing (which uses low-E, low-emissivity coatings to selectively allow more visible light than infrared heat radiation), that many buildings can have such large window areas and remain comfortable in the summer,”

Glass in photovoltaic applications Photovoltaic technology, which converts solar energy directly into electricity, is seen as a green option. It uses glass to suit various requirements. Derek Burston explains... Photovoltaic panels come in various shapes and colours, offering flexibility for design integration and building integrated applications (BIPV). The most common photovoltaic technology is based on crystalline silicon solar cells, where glass acts as a protective outer layer, while transmitting solar light to the photovoltaic cells interconnected underneath. Other technologies include thin film photovoltaics, where solar cells are deposited as a sequence of thin films on glass. Here, transparent conductive coated glass can be used as the front glass upon which films are grown. The conductive coating not only allows light through to the photoactive films but also conducts the generated electricity out of the modules. Concentrated Solar Power (CSP) systems are used to produce electricity from the sun at utility scale. They are mainly used in regions with high levels of solar irradiance, and use lenses or mirrors to concentrate a large amount of sunlight onto a central receiver, thereby producing electricity, either by concentrating the sunlight onto a high-performance photovoltaic cell or by heating a transfer fluid to supply heat to a conventional thermodynamic power plant. For CSP systems, extra clear glass and mirrored glass are used to redirect accurately the maximum amounts of light towards the focal point.
concedes Straube, but points out, “Nevertheless, even very good commercial clear glazing still allows about one-third of the sun’s heat to enter.” He elaborates: “Glazing systems, including almost all modern high-performance ones, have very little ability to control heat-flow and solar radiation. Older windows also did little to control heat loss and solar gain. Hence, most older buildings had restrained window-to-wall area ratios. Most of the tremendous performance gains in glazing technology over the past 25 years have been squandered on increased window area, not improved performance.” Gavin Bannerman, General Manager of Pentagon International FZCO, which 74
carries the brand Laminas Window Film, adds, “Over half of energy costs typically come from cooling a building, while 80% of heat build-up comes from solar radiation through the glazing.” Burston, however, believes that with the drive towards zero carbon homes and the subsequent need for the glazing to perform well, triple-glazed windows are at the forefront of systems that will meet the standards expected. But he, too, questions its necessity in the region, when he asks: Is triple glazing a must in the Middle East? He admits that opinion is divided on the issue, as triple glazing is widely used in countries with cold climate. “The ultra-low energy

Glass has transformed the way in which the world builds and lives. Glass has not only made it possible to reach unimaginable heights, but it has also given us the chance to enjoy the view PassivHaus standard requires triple-glazed windows with a U-value of no more than 0.8,” he explains. “Though a U-value as low as 0.8 sounds very impressive, the additional energy saving is minuscule, whilst the payback time for triple glazing (like double glazing) is high compared to other energyefficiency improvements. The key benefits are really to do with comfort – double-glazing makes a modern house more comfortable to live in; triple glazing makes it even more so,” he reveals. Straube believes that good day-lighting design can reap the benefits of glazing using vision glass covering less than
half the enclosure. “Numerous studies have shown there are no daylighting or energy benefits with window-to-wall ratios over 60%, and in most cases, an area of between 25 and 40% is optimum (that is, lowest energy consumption),” he says. “Carefully choosing, and then specifying, overall system U-value, SHGC, and VT is the best start to delivering high-performance glazing on your next project,” Straube adivises.
Tinting and filming
Window film – a clear layer of high-performance polyester fixed to the internal or external surface of existing glazing – can upgrade the performance of the glass in terms of solar control, heat rejection, glare reduction, UV blockage and light management, believes Bannerman. “While being visually clear, window film can come in a range of shades/tint levels, each with varying degrees of solar control properties,” he explains. Speaking of the significant benefits of glass tinting in terms of maintaining the energy efficiency of HVAC equipment, he says: “By filtering sunlight, rejecting heat, glare and harmful UV rays, films neutralise hotspots and keep interior temperatures more stable. This means that the cooling system works less, peak demand is lowered and the air conditioning operates more efficiently and inexpensively. Direct savings result from lower energy bills and prolonging the service

One for the road The design of glass is continuously adapting to the changing needs of vehicles. Derek Burston lists a few...
Thermal comfort
Today’s increased use of glass in cars means that without the right technologies, more solar energy will penetrate the interior of the car, causing high temperatures. For example, when the outside temperature is 27°C, without anti-heat technologies, a car’s interior can heat up to 58°C in a few minutes. Combating this solely by way of air conditioning would be an environmentally unfriendly approach, leading to higher fuel consumption and CO2 emissions. In recent years, the industry has developed solar control glazing. This type of glass is specially engineered to reduce vehicle cabin by up to seven or eight degree C temperature, and reduce heat penetration in vehicles exposed to solar radiation by over 25%. A significant amount of energy is, thus, saved from powering air conditioning units while passenger comfort is safeguarded.
Solar control glazing
Solar control glazing has a coating that allows it to reduce the transmission of solar heat from the external environment, while still permitting the optimal light transmission essential to ideal
76
driving conditions. This type of glazing can reduce by over 25% the heat penetration in vehicles exposed to solar radiation, thus reducing the need for the use of fuelhungry cooling systems. Dark-tinted glazing and switchable glazing also have solar control properties, which can reduce the amount of solar heat entering the vehicle’s cabin.
Acoustic comfort
Noise can cause disturbance and stress and affect occupants’ health if they are exposed to it over a prolonged period of time. Acoustic laminated glass technologies have been developed to combat levels of noise penetration in vehicles.
Dark tinted glass
It keeps the interior cool by absorbing solar energy and, at the same time, offers privacy for rear-seat passengers. (Dark tinted glass is not permitted for the driver and forwardpassenger windows and, of course, for the windscreen.) They are available in several colours and each colour in several shades from light to very dark.

By filtering sunlight, rejecting heat, glare and harmful UV rays, films neutralise hotspots and keep interior temperatures more stable life of HVAC equipment, while reducing the capacity required gives further savings.” He claims that the payback for his company’s window film installations is usually under three years. Bannerman highlights that window films can also help in promoting a better work environment and IAQ. “As improved comfort levels in a building’s internal environment result in increased productivity for office staff as well as reduced sick days normally caused by eye strain or sun glare on computers,” he says. “With 99% of UV rays rejected, existing furniture and floorings are protected against sun damage and fading, which means less harmful chemicals are released into the workplace atmosphere.” Bannerman bemoans the fact that though there has been a steady increase of awareness in international markets, such as Europe and the United States, about the efficacy of window films, the region still has a long way to go. “This is surprising, as our climate is one of the warmest in the world with a daily need to upgrade a struggling building material such as glass,” he says. “At Laminas, we now can offer
companies full building modelling reports with accurate estimations on ROI and potential savings." Interestingly, more than sustainability, it’s the cost factor that might motivate customers to go in for tinting and using glass films. “We have found that the ROI is the key figure when presenting to decision makers rather than any environmental benefit the installation would bring,” Bannerman reveals.
Conclusion
Since glass has come to mirror sophistication, it enjoys demand and is hypothecated to per capita growth. It undoubtedly has many advantages. Thanks to glass facades, we no longer have to live or work in claustrophobic brick monoliths. While greater use of daylight, the luxury of being part of the outdoors while still being indoors and aesthetic considerations warrant mammoth glass towers, they could turn into heat traps and consume energy, even as they attempt to save it. And excessive glazing comes with its own attendant problems. Glass industries are investing in intensive R&D programmes to develop new products to enhance energy efficiency, environmental performance and recyclability. In this regard, Burston supports more stringent regulations in the region similar to those in place in Europe. But he sounds a caveat: “European glass industries are proud of the environmental gains that have been achieved. Investments in state-of-the-art environmental systems enable our industry to comply with some of the world’s toughest environmental regulations, but which, on the downside, unfortunately entail extra costs that are reflected in the increasing production costs.

from outside the EU makes it tough to absorb the higher production costs over our competitors.” Bannerman on his part believes that window film is the answer. “It ticks the boxes in at least six different categories when applied to certain building codes and standards, whether it be the obvious areas of improving cooling efficiency and managing internal comfort or the more complex areas, such as aiding day-lighting and reducing light pollution,” he claims. “For any existing buildings looking to get certification, window film is a definite must.” In the final analysis, a fine balance needs to be maintained between thermal comfort, energy efficiency and system performance costs. This could be achieved by technologically innovative methods and a judicious use of glass. Yes, a lot of reflection still needs to be done on glass.
A 37-storey tower nicknamed the “Walkie-Talkie” because of its shape, in London’s financial district, caused concern a few years ago, as it radiated heat around it. Thanks to its concave design and the glass façade, it focuses and amplifies sunlight. A beam of light bouncing off from it was hot enough to reportedly melt parts of a Jaguar sports car parked nearby, and also sparked a fire at a local barber shop. A reporter is said to have even managed to cook an egg by placing a frying pan directly under the beam. However, according to recent reports, developers, Land Securities have addressed the issue by fitting the south face of the building with a “brise soleil” awning that will act as a sunshade and a permanent solution.
Comfort and efficiency – a balancing act Gavin Bannerman of Pentagon International (Laminas Window Film) believes window films will play a major role in the UAE’s vision on energy efficiency and even safety. He shares his insights with Glaiza Seguia-Godinez:

“Our projects always meet a balance between natural daylighting and thermal comfort, which is why we have a regionspecific range of window films which can meet any requirements that may be needed. Once a building is complete and there are still thermal issues with the building envelope, there is little choice other than to apply window film to upgrade the performance, as replacing the glazing is too costly and disruptive. Window film is a quick and easy solution with minimal disruption for a building’s operations. “Dubai International Airport is an ongoing
project for us, focused on improving comfort and efficiency. Our glazing safety products are also being widely used. These clear safety films can also contain glass fragments in the event of breakage, such as thermal cracking, which is an issue here in such a hot climate. “The construction industry, as a whole, has become more aware of the climate we are living in and how our buildings should be put together to ensure energy consumption is reduced. With the introduction of building codes and regulations, it has definitely changed the way architects are designing properties, and I believe more buildings are now built with a long-term vision in mind. In addition to new builds, the retrofit market will be employing upgrades to lighting, HVAC and glazing for the considerable future, as buildings are brought up to standards or replaced.”

egulations for constructing and operating a refrigeration system are stipulated by law, as well as the question of how to dispose of different refrigerants. But it is precisely the variety of regulations at European, national and regional level that often makes it difficult for operators to keep essential aspects in mind: Who is responsible for refrigerating systems and what regular checks are required for their reliable operation? eurammon members Raymond Burri,
80
Director at Walter Wettstein AG, and Rainer Brinkmann, Technical Support Industrial Refrigeration at Johnson Controls, explain what operators need to consider in terms of plant safety.
There is still a great deal of uncertainty when it comes to user responsibility. Exactly who is the operator by law and when does his responsibility for system operation begin? Rainer Brinkmann: Basically, the owner is the operator. Many people often don't know that there
Climate Control Middle East November 2014
are different legal aspects involved with regard to the point in time of initial commissioning. While the system manufacturer is still responsible for initial commissioning during the installation phase of the project, the user already bears sole responsibility for commissioning during the trial-run phase following hand-over or after the transfer of risk. Once the system has been handed over, the operator is also responsible for hazard assessment pursuant to ยง 3 of the Industrial Safety Regulation; this may include measures for operational safety.
What does the law say in your country and what do operators have to bear in mind?
Raymond Burri: In Switzerland, the Chemicals Risk Reduction Regulation (ChemRRV) says which refrigerants are to be used for which application and refrigeration capacity. As far as natural refrigerants are concerned, a system logbook has to be kept constantly up to date for systems with a filling of more than three kilogrammes. In addition, preventive maintenance measures are to be conducted at least every 12 months and also recorded in the system logbook. This includes a leak test as well as checking the alarm devices, mechanical ventilation, detectors and personal safety gear. An annual inspection of the safety devices is also compulsory.
If it should transpire that instructed maintenance work has not been performed correctly despite issuing a fully comprehensive order, the operator can take recourse against the instructed company
Rainer Brinkmann: In Germany, the user is obliged by law to obtain official approval for certain refrigeration systems. This also entails fulfilling regulations for installation, commissioning and periodic inspection. However, the legislation is rather complicated: Together with EU Directives and national laws for construction and quality, specific state regulations also apply to operating the systems, which are often not known to many companies.
Regulations for Operational Safety (TRBS) as well as the Occupational Safety Act and the Ordinance on Hazardous Substances. Compliance is also necessary with the accident prevention regulations of the professional associations (BGR) which indicate measures for fulfilling indispensable protection objectives. For example, BGR 500 chapter 2.35 "Operating refrigeration systems and heat pumps" prescribes regular safety training sessions for the employees.
What are the central regulations in Germany that every operator ought to know?
Can users pass the responsibility on to third parties, and who is liable in the event of any damage?
Rainer Brinkmann: It depends on several factors, such as system type or which refrigerant is being used. For example, systems using refrigerants that need special safety precautions often go through preliminary
In Germany, the user is obliged by law to obtain official approval for certain refrigeration systems. This also entails fulfilling regulations for installation, commissioning and periodic inspection
Raymond Burri: Both in Switzerland and in Germany, it is common practice for approval with subsequent regular monitoring, maintenance and inspection. However, Germany does have central laws and regulations that every user ought to know, such as the Federal Pollution Control Act (BImSchG), the Industrial Safety Regulation and the Technical Regulations for Operational Safety (TRBS).
Could you give a few concrete operatorrelevant examples of these regulations?
Rainer Brinkmann: The BimSchG, for example, is important for operators of systems subject to approval with an ammonia charge of more than 3,000 kilogrammes. It states that the responsible approval authority can stipulate periodic safety inspections by an expert for these systems. Second example: In terms of occupational safety, the user has to heed the Industrial Safety Regulation and the Technical

users to instruct third parties to undertake regular maintenance of the system. As a rule, the third party will be the system manufacturer. If it should transpire that instructed maintenance work has not been performed correctly despite issuing a fully comprehensive order, the operator can take recourse against the instructed company. Nevertheless, the operator remains liable by law, and this also includes bearing the consequences in the event of damage.
In other words, operators always depend on the professional expertise of the manufacturer. How would you describe the role of the system manufacturer in this context?
Raymond Burri: Every refrigeration system manufacturer should provide advice about necessary approvals and safe operation of the refrigeration system, especially for future operators. The support we provide for systems that we have designed and installed usually extends across the whole service life. As a result, we are familiar with every system and can draw early attention to pending maintenance measures. We also offer our customers regular training courses to keep them informed about refrigeration technology and operator obligations.
While it is often difficult for small companies to keep up to date on a broad scale, large companies will have specialist departments that deal with the whole issue of user responsibility
Do you think that operators are adequately informed about their obligations?
Rainer Brinkmann: There are great differences here. While it is often difficult for small companies to keep up to date on a broad scale, large companies will have specialist departments that
82
Climate Control Middle East November 2014
deal with the whole issue of user responsibility. For small companies in particular, it is vital to keep themselves well informed. Assistance can be provided here by the professional associations. Information is also available in special literature produced by the refrigeration system manufacturers, drawing attention to the operator's statutory obligations.
What exactly do you understand by exemplary safety management?
Raymond Burri: Generally, Swiss legislation offers a good basis for exemplary safety management – from regulations and inspection obligations through to regular leak testing. Operators working with natural refrigerants have to take additional safety management measures. In Switzerland, it is obligatory for users of larger NH3 systems with a charge of more than 2,000 kg to keep an operation plan available for the emergency services, which includes simplified drawings of the buildings together with piping and instrumentation diagrams, which show all safetyrelevant manual stop valves and components. Rainer Brinkmann: Safety
management is an on-going process under the control of the business Managing Director or a safety officer, and all employees must be involved. Firstly, the operator has to produce hazard assessments, which are then used to stipulate safety measures of all kinds. These include any necessary inspections, checks and regular safety instruction sessions for the employees. The effectiveness of these measures has to be checked continuously during on-going operation. Any necessary corrections must be implemented and, above all, comprehensibly documented. n The complete interview on the eurammon website at: http://www.eurammon. com/press-room/ background-articles. eurammon is a joint European initiative of companies, institutions and individuals who advocate an increased use of natural refrigerants. As a knowledge pool for the use of natural refrigerants in refrigeration engineering, the initiative sees as its mandate the creation of a platform for information sharing and the promotion of public awareness and acceptance of natural refrigerants.

FREQUENCY CONVERTERS
Finding the perfect match Arguing that frequency converter technology makes for energyefficient buildings, Tobias Dietz demonstrates how fitting pumps and fans with frequency converters can yield better results when speedcontrolled and matched to the actual capacity requirement
Cascade circuits are a good choice for systems where several pumps share the load. They ensure optimal efficiency, reduce wear and energy costs, and achieve balanced loading by lead pump alternation.

or years, energy prices have been rising. Not surprisingly, interest in energy savings for industrial and commercial applications has soared. Overall cost reduction and energy savings have never been more topical. Owners and operators, therefore, seek energyefficiency measures in production facilities as well as in residential and office buildings. In this regard, electrical drive technology
84
is a key technology for enhancing energy efficiency, and currently the most effective way to reduce energy consumption quickly and significantly.
Speed control of pumps and fans with quadratic load torque They usually operate out of sight, but pumps, fans and compressors are vital to many aspects of our everyday environment. We expect them to operate reliably at all times, for without the tasks they
Climate Control Middle East November 2014
perform, such as ventilation and cooling of buildings, our lives would be a good deal more difficult. Apart from the functions they perform, pumps, fans and compressors have potential for savings. In case of fans, centrifugal pumps and compressors, which have a quadratic load torque characteristic, energy consumption falls proportional to the motor speed to the power of three. A widely used solution for such equipment is to fit a modern frequency
In case of fans, centrifugal pumps and compressors, which have a quadratic load torque characteristic, energy consumption falls proportional to the motor speed to the power of three converter so the speed can be perfectly matched to the actual capacity requirement. In most situations, pumps and fans in building services are configured for worstcase scenarios. For example, an air conditioning unit is dimensioned for the hottest day of the year, when it has to work at full capacity. This naturally means that it operates under partial load the rest of the time. A similar situation is true of pressure boosters in high-rise buildings. This is where frequency converters come into play. Declining frequency converter prices also make them an increasingly attractive proposition. However, it needs to be borne in mind that not all pumps and fans are suited to speed control.
Speed control as a savings measure
To avoid surprises where speed control for pumps and
fans is concerned, operators planning a project should remember that changes in speed alter the operating point and, as a result, affect the efficiency of fans, pumps and compressors. Technical, commercial and logistics issues must therefore be considered before an investment decision is taken in order to avoid uneconomical and counterproductive measures. To ensure that cost and effectiveness are up to spec with speed-controlled pumps and fans, frequency converters should not be selected on the basis of the lowest price, but instead, selection should be based on which one yields the most cost-effective and efficient solution throughout its entire lifecycle.
It needs to be borne in mind that not all pumps and fans are suited to speed control
Efficiency curves of fans, pumps and compressors
In older systems and even in some new facilities, pumps and fans are often used with dampers, valves or threeway valves. These adjust the pressure or flow in the system to suit the current capacity requirement. If a centrifugal pump is controlled using a throttling valve, throttling moves the machine’s operating point along the pump curve. The required energy is reduced only minimally compared with the pump’s set point. If a pump is speedcontrolled, the operating point moves along the system curve. The required energy is reduced by the power of three compared to valve control.
November 2014
At half speed, a pump, for example, needs only an eighth of its nominal power. This behaviour is the same for all pumps, fans and compressors with a quadratic torque characteristic. In addition to pump and system characteristics, the graph (Figure 1) shows a number of efficiency limits. Both valve control and speed control cause the operating point to move out of the optimum efficiency range. Figure 2 shows the energy consumed by a selected pump operating under speed control. At around 32 Hz, additional losses in the pump start to exceed the savings. The optimum energy efficiency frequency in the system shown is thus 38 Hz. If the pump were

The optimum energy efficiency frequency in the system shown here is thus 38 Hz. If the pump were not speed-controlled, the energy balance would be significantly worse.
not speed-controlled, the energy balance would be significantly worse. As mentioned earlier, building services systems must be dimensioned to handle the peak load. This unavoidably means that they operate under partial load much of the time. Manufacturers of fans, pumps and compressors take this into account, designing some units so that optimum efficiency is achieved at approximately 70% of the rated delivery volume. When upgrading existing systems or developing new designs, users should consider the

efficiency may be as low as 10 to 20% with a wide control range and a single pump dimensioneD FOR WORST-CASE OPERATION
Climate Control Middle East November 2014
Combining a fan, pump or compressor with a frequency converter yields a speed range in which the system saves energy. The machine should operate in this range most of the time. If the difference between the maximum required capacity and average partial-load operation is too great, the operator should seek another solution. In such a case, the user needs a solution with several units that are nevertheless able to offer the advantages described above. Some examples of such systems are pressure booster or irrigation systems, fans in multi-cell cooling towers, secondary water pump systems typically found in cooling systems and pump systems for district heating. There are many reasons for using this type of system architecture. The most important reason is optimal setting of the set point according to the actually required system capacity. For example, efficiency may be as low as 10 to 20% with a wide control range and a single pump dimensioned for worst-case operation. In contrast, a multi-pump system can usually achieve an efficiency of over 70%. This makes cascading a sensible option. In addition, investments for the conversion of existing systems often pay for themselves relatively quickly. When pumps are cascaded, one speedcontrolled pump handles the base load. If the load increases, the frequency converter cuts in more pumps one after the other.
At half speed, a pump, for example, needs only an eighth of its nominal power The pumps accordingly operate at maximum efficiency whenever possible. Pump control ensures that system utilisation is always as energy efficient as possible. The same approach can be used for fan control. It needs to be noted that suitable cascade controllers are available as external assemblies.
Ask your specialist
To ensure obtaining the best solution with maximum energy efficiency, users should always assess the advantages and disadvantages of a particular technology. Here it is important to bear in mind that the quality of a technical solution is usually proportional to its price. As the vast majority of today’s users cannot possibly be familiar with every last detail of all technical devices, and as the interplay of components makes it still more complex, it is certainly worthwhile to seek advice from experts where necessary, and to discuss all technical advantages and disadvantages with them.n

to achieve LEED Silver certification. Design began in January 2011, and the new CUP is expected to be completed this year. Clark/McCarthy, a Joint Venture, was awarded the design-build contract to replace the airport’s CUP. Murray Company was the installing contractor and ARUP were the consulting engineers.
The challenge
The CUP that cheers Selecting a Vortisand cross-flow microsand filter helped demonstrate a seven-fold difference in operating costs and made dollars and sense for the Los Angeles International Airport’s central utility plant. We bring you the case study. The background
The replacement central utility plant (CUP) project was a design-build project involving construction of a new CUP to replace the existing CUP at Los Angeles International Airport (LAX). The purpose of the project was to accommodate the increased utility demand associated with improvements to the Tom Bradley International Terminal (TBIT). The replacement of the 75,000 square-foot CUP 88

was constructed between the existing CUP and the existing Federal Aviation Administration (FAA) air traffic control tower. Upon completion of the replacement CUP, the existing CUP was demolished and used for the site of the thermal energy storage (TES) tank. The project also included construction of new cooling towers with a 20,000-tonne cooling capacity. Systems and their components were designed and constructed
Water from cooling towers attracts and absorbs airborne contaminants on a continuous basis. Typically, 85% of suspended solids in chilled water and even hot water loops are smaller than five microns in size. Scientific studies* have shown that these small particles (five microns and less) are the adherent contaminants that lead to fouling of heat exchangers and a reduction in efficiency. A reduction in fouling was a key consideration in the design of the cooling system for this project. Not only would significant savings in energy be realised but a reduction in submicron particles also inhibits biological activity by removing a source of sustenance for bacteria. In order to properly assess filtration requirements, an LPA (Laser Particle Analysis) test was conducted on existing LAX cooling tower systems, CHW and HHW circuits. The filtration challenge was clear: 95% of all system water TSS were smaller than five microns.
The solution
When designing the filtration system for the cooling system, the designers had initially looked at a system that combined a traditional sand filter with sweeper piping (typical filtration efficiency 20 microns). Additionally,

“It’s time for
an intellectual renaissance” Prakash Chablani, Managing Director of Dubai-based Unigulf, once a tentative entrant to the HVAC industry, now believes in being a game-changer…
My education
I was born in Kuwait in 1962 and belong to the third generation in the family to live in the region. I started my education in Kuwait, eventually going to the United States, from where I earned my bachelor’s degree (with honours) in Industrial Engineering in 1983. After that, I got admission to do Business Studies at Stanford with full scholarship, but as fate would have it, I was unable to join the course, as my mother had to be hospitalised for four months in Mumbai, owing to poor health, and I had to be with her.
Co-opted into the business
My coming into the HVAC industry was a simple accident. But I believe there’s no such thing as an accident; it’s fate misnamed. It so happened that after graduating and not being able to pursue my education, leading to a career, and owing to my family’s needs, I had to be part of my father’s HVAC export business, which he had set up in the United States in 1983. In 1986, my father started Unigulf in Dubai, and I took independent charge of it in 1990. To give a bit of the back story, Dubai in those days was vastly different from what it is now. Even simple HVAC products and systems were difficult to obtain. They had to be imported by a contractor, as opposed to getting them through a local channel. This was always a challenge then. Therefore, the base concept of stock, sale and distribution of quality products was needed. My father started out working for a leading contracting company – Al Futtaim Engineering – in the early 1970s. During his time as a contractor, he understood the needs and potential opportunities for supplies of basic materials needed in an HVAC system. And Unigulf was born out of this need, and I later got co-opted into the business.

At The Big 5 Show which opens in the coming few days, we are going to introduce our preinsulated chilled water piping systems In pursuit of gamechangers
While growing up in Dubai in the 1970s, I remember one of the units of Al Futtaim Engineering was a metal duct workshop. I had observed that the difficult part was to turn the ducts – that is, to branch them, because that’s where you have leakages. In 1984, while in the United States and working with my dad, I saw flexible ducts for the first time, and we brought them here and tried to change the mindset of people. It was not easy to do so, but today, flexible ducts have become common. Another game-changer was rubber foam insulation. Traditionally, it has been fibreglass with its coatings and vapour barriers. I was fascinated by rubber foam, when I saw it for the first time at an exhibition in Paris in 1992. It was at the K-Flex booth. I tried to import it, but it did not move in the market here. That’s when I realised it’s not enough to merely bring the product if you can’t deliver it as a solution. We have to deliver it as a duct. So we bought 94
out an ailing ducting unit in Sharjah in 2001. The unit was a small one, where they fabricated sheet metal ducts. We used the facilities to make rubber pre-insulated ducts, and it took off. By then, I had developed an itch for manufacturing, and we evolved a concept of manufacturing panels of preinsulated ducts, and side by
side, the Sharjah fabrication unit also grew. Our growth has been to such an extent that we have supplied our ducts to marquee projects like Dubai Mall, Ferrari World in Abu Dhabi and the New York University campus, also in Abu Dhabi. Our business approach has been that whenever you need large quantities in the shortest period of time, it has to be Unigulf. That’s our driver. You simply have to deliver on time and meet the precise needs of customers. This approach has kept us ahead among all our competitors that supply ducts. Very soon, we are going to come up with another gamechanger. At Big 5 Dubai 2014, we are going to introduce our pre-insulated chilled water piping systems. We see the systems as making life easier for contractors.
The turning point
The year 2000 was a renaissance for me. I was always trying to find out what was the real need of contractors. You see, contractors don’t make that much money on ducts; they make more money on chillers. In the case of ducts, they
have to pay high labour costs for installing hundreds of thousands of square metres of ducting. It’s a labour-intensive process. So the concept of pre-insulated ducts was a watershed. With pre-insulated ducts, they no longer had to employ a large number of workers to insulate the duct at the site; instead, they could buy the readily fabricated insulated ducts and merely install them. That way, contractors could do away with thousands of workers from the job site, which at one go helped them cut costs as well as put the ownership of quality on the suppliers.
A bouquet of challenges for the market
I find that people are not updated with changes. I see a transient population and a culture of copy and paste, even in specifications. Market awareness and being updated on specifications, the products available and certification together constitute a major challenge. People are resistant to change. This aversion to change in line with conceptual and technological developments in base

I see a transient population and a culture of copy and paste, even in specifications
I’d like to see regular interactions happening within the industry involving clients, consultants and contractors, with the objective of sharing information about products and applications. From an industry point of view, I’d like to see the creation of an independent body with no vested interests to provide business-related information. Many years ago, a group of suppliers took the initiative to hold regular meetings, and the issue of payment came up quite often for discussion. I know, because I was part of the group, along with Hira, Nasser Al Sayer and Al Shirawi. When it came to delayed payments, almost everyone in the group had a problem with one particular contractor, which was like an alert for all of us. I would, therefore, like to see a group formed, which would address challenges faced by suppliers. It could collect information related to payment track record of companies and, thus, enable us to exercise caution while supplying to

applications is another roadblock. Yet another challenge is that workmanship warranty is non-existent. And so this region is lagging behind. Ownership of quality workmanship goes beyond standard warranty. Another challenge is the uneven playing field for quality product suppliers. One of the major ailments here is misrepresentation. People write things like “UL”, and even consultants don’t verify them. If a manufacturer or supplier gives a file number, they don’t verify it. UL is present in the UAE, and I would like to see them do something about this. There’s simply no accountability here. In the United States, you can’t write anything you can’t prove. I believe it’s time for an intellectual renaissance. Ownership of financial obligations is another obstacle. There are small companies that sell good products. But they are not willing to take risks, owing to delayed payments. They can’t afford to wait for months to receive payments.

Hope on the horizon
Besides the continuous rationalisation and consolidation, I think the marketplace for the industry has just stepped into its best period in history, not only for the UAE but also for the region. Due to the rapid increase in regional population and an ever-growing number of expatriates, with sustainable initiatives, such as trade, tourism, healthcare, aviation, mass transit and resourcedriven industry well in place and further augmented by global events, such as Expo 2020 and FIFA 2022, the next eight to 10 years can be well planned. And who knows, the Asian Games could once again come to the region. And contrary to popular belief, the impact of the recent oil price corrections will not be a hindrance to the optimism ahead for the next seven to 10 years. I believe that various opportunities, in general, exist for the industry in this optimistic business period ahead. In my opinion, the market has matured to the point of evaluating cost from a more holistic point of view. This in itself is the most conducive atmosphere for continuous R&D and acceptance of innovation. Things are happening very fast. My business instinct tells me that we will see growth here up to 2025 and even beyond. At Unigulf, we are aligning our business plans to the plans of the UAE. We are driving our plans with the same momentum as the wise rulers here. The emphasis here in the region is about better governance and the empowerment of people. These are the basic aspects we need to establish. Is the region on a success 96

I think the marketplace for the industry has just stepped into its best period in history, not only for the UAE, but also for the region path? I believe success is a relative word. The total socioeconomic situation of the world leaves only this region as the place with the highest GDP in the world. So there is flow of money and resources here, which means you will have success. As far as the US, Europe and Japan are concerned, I feel the period
Climate Control Middle East November 2014
of growing is over, and now those areas are concentrating on technology as the driver for growth. Here, though, there still are basic needs that have to be met, so growth is happening.
My wish-list
At an individual level, as Unigulf, we see further
expansion of our business concepts in line with our vision, such as adding products to be a multiplesolution provider; giving a more complete solution for applications; making more products available that are further conforming to changes in the industry, certification and local regulations; continuously working with our customers to make them further competitive with introduction of new products and concepts; increasing backward integration with principals and partners to make the marketplace more affordable and competitive; and focusing a part of the business to service-related solutions to increase the customer-base of the company. More specifically, Iâ&#x20AC;&#x2122;d like to focus further on the insulation industry to the point of becoming a â&#x20AC;&#x153;one-stop solutionâ&#x20AC;? as well as to protect the future from the general woes of resource depletion and global warming.
My mentors
My life is my business, so my father is a mentor. While at university, Dr Robert Shapiro, my 70-year-old Math tutor was a mentor. He had nine
PhDs! Dr Peter Woss, R&D Director at K-Flex was another person I learnt from. In fact, everybody I interact with in business and life is a mentor. Anyone who positively impacts us is a mentor.
My philosophy for Unigulf
I may have entered the HVACR sector by accident or as a quirk of fate, but I believe that it’s a platform for me to carry on and improve on the vision of my mentors for the marketplace and the industry, with the changing times and new technologies. It has always been important for me to maintain a simple core philosophy for Unigulf. It’s my aim to build a 100-year company, nothing less. I want the company to stand the test of time. Behind this is the conviction of business sustainability and to remain at the forefront when it comes to offering products. And in order to achieve such sustainability, Unigulf has always aimed to remain at the forefront of new technology – and our associated R&D pursuits – without however, losing sight of continuing to approach our internal processes with a lean, efficient and adaptable methodology. Externally, our drive is to make available to the industry high-quality and gamechanging products that do not just meet existing standards, but set new benchmarks in the HVAC industry. For instance, many years ago, Unigulf brought a simple product like flexible ducts, which despite its simplicity, was a game-changer. The philosophy is the result of my understanding of the market based on several years of observing and interacting with people. My globetrotting has given me exposure to various products and solutions, and my objective with Unigulf is simple – to make life simple for contractors by giving
against 18-year-olds. To everybody’s surprise, the project was a food truck to sell samosas in different localities!
Away from business…
I have been fortunate enough in life to be able to pursue my interests and hobbies through work. I enjoy travelling and have always been fascinated by cultures – in learning how people from different backgrounds think, live and behave – and in finding similarities in all of us. However, due to the intensive nature of my professional requirements, I almost always choose to spend any free time available with my family at home in Dubai.
It all begins and ends with hard work them the most apt products, which would help them finish their assignments in a manner beneficial to them. If they win, so do you as a supplier or manufacturer. It’s about understanding needs at the ground level and giving products to match the needs.
My philosophy of life
I strongly believe in resilience – in the ability to be willing to take the hits that life inevitably throws at you, until you reach a point where you begin to accept and almost enjoy the chosen path. Every person must develop their own style to overcoming life's challenges. Envy is ignorance. Imitation is suicide. The key is to boldly face the inevitable external and internal resistance to our beliefs. It all begins and ends with hard work. In the last 25 years, I chose to make many personal sacrifices to endure and grow my father's legacy, and in turn, to give my family the best possible life I have the strength to provide. These are some of my guiding beliefs.

TEMPORARY DISTRICT COOLING PLANTS Introduction
Due to the extreme climate of the UAE, all buildings have conditioned air. Conditioned air is produced in two ways: • Localised air-cooled air conditioning units, ie, split unit air- cooled chiller. • Central District Cooling plant (DCP) using either water or air-cooled chillers delivering chilled water to energy transfer stations (ETS) within larger buildings, which then supply via heat exchanger’s chilled water to air conditioning units (normally Air Handling Units or Fan Coil Units FCUs) to produce conditioned air
Temporary District Cooling plants – a closer look
With a hypothesis that temporary cooling plants come with several benefits, Imran Ali, GM Argonaut, and Darren Hunt, MD Two Fold United E&M Contracting, in a technical and commercial collaboration, conducted a detailed case study of the next generation temporary cooling plants. Here, Darren Hunt presents the findings of the study.
98
Climate Control Middle East November 2014
The most economical and environmentally friendly way to produce conditioned air for large buildings is via a DCP. DCPs generally take 24 months from concept to operation and require a huge amount of investment to cover the following: • Feasibility study, design, authority approval • Construction costs • Utility costs • Operational costs There are companies which offer DCPs as turnkey solutions to clients in the UAE. These companies invest, design, construct, operate and sell District Cooling to clients. The contracts are generally for a 30-year term. There is a shortage of DCPs in the UAE to provide conditioned air to buildings and there are many companies which offer temporary solutions that generally consist of: • Temporary power via diesel generator • Temporary air-cooled chillers • Temporary electrical distribution, cabling and chilled water pipes Temporary cooling plants are often procured for a 12-month period. However,
since the financial downturn and reduced investment in DCPs, it is quite common for these temporary cooling plants to be in operation for more than three years. This case study considers a more environmentally friendly, cost-effective solution to clients who are currently connected to temporary cooling plants.
Conventional temporary cooling plants
Conventional temporary cooling plants are generally harmful to the environment due to: • Diesel exhaust fumes • Chiller exhaust • Noise pollution • Their unsightliness These come at considerable cost to the client:

Additionally, they do not have a great level of control, which increases costs and provides air conditioned spaces with very little environmental control.
The next generation temporary cooling plants Two Fold have designed and developed what they believe to be ‘the next generation’ temporary cooling solutions. The design of the next generation cooling solutions takes into account: • Environmental considerations - The impact on the environment of conventional cooling plants
• Automated controls – Temporary cooling plants which can achieve the same KPIs of permanent cooling plants • Rental costs – A cost comparison of the temporary equipment using generators and a permanent electricity supply • Running costs – A cost comparison of the fuel for generator power versus utility provider costs for permanent power • HSEQ – Safety and quality of the installation Each of the above will be addressed in greater detail below.

Automated controls
impact on the environment using diesel generators for months/years to supply thousands of refrigerant tonnes of temporary cooling is devastating from the fume exhaust point alone. Other environmental factors to be considered are control of fuel, noise pollution from the diesel generators, along with the aesthetic damage caused to an area. Our design eliminates the diesel generators from supplying power to the temporary chillers and utilises a permanent 22kV / 11kV power supply direct from the utility company. By eliminating the diesel generators, you eliminate the control of a hazardous substance ie, diesel – the fumes which are exhausted into the atmosphere – and the noise pollution. However, in the case of the next generation cooling solution, since they are connected to the utility provider’s network, they are subject to the authority regulations and are strictly regulated,
The next generation temporary cooling plant has an automated control system which includes Chiller
100
Conventional temporary cooling systems have very limited control. The chillers supply a constant flow of chilled water at a leaving temperature to a consumer. Generally, these are based on a 9 ΔT, ie, if the temporary plant delivers the chilled water at 4.5°C, it expects the return temperature of the water from the consumer to be no more than 14.5°C. If a plant is supplying to multiple buildings and ETS rooms, this lack of control will mean inadequate supply, as different buildings will have different loads, different return temperatures and different demands, which cannot be catered to without an automated control system.
Chiller Header Control Philosophy
Header Control Philosophy. This means: There are a number of 400 TR chiller sets, each consisting of two chillers connected in a series, a single pump, isolation and by-pass control valves. Each set is connected to a common header. The number of chiller sets enabled is based on the load summation from each building of the total buildings. This load is calculated with an energy flow meter on the return from each building. The flow meter looks at supply temperature, return temperature, flow and ΔT. The chiller set header is also monitored for flow, supply, return temperatures and ΔT. The ETS PLC is interfaced to each building controller to monitor each building, so a clear picture of building performance and ETS control is given. The flow, supply, return temperatures and ΔT along with the differential pressure are monitored within each building to ensure the Key
Chiller Header Control Philosophy - Load Sequence
Climate Control Middle East November 2014
Performance Objectives are being met and to double check the total load given by the total system load at the header position. The number of chiller sets enabled is based upon the summation of the load and ΔT from the chiller set header, whichever demand is greater. The first chiller set is enabled in such a way that if the cooling capacity of one chiller set is insufficient, then another one is started, and so on. Should the ΔT from the header start to fall, then the chiller sets will be disabled to maintain ΔT. The end-users are responsible for maintaining the ΔT on their systems, ie, beyond the building heat exchanger(s). The inlet and outlet temperatures of a chiller set are measured for monitoring and diagnosis purposes. The usage of the chillers is distributed in such a way that all the chillers are working at their most efficient. And calculating runtime hours
always working for approximately the same runtime, ensures that after each duty cycle (1 -13) the chiller set with the least amount of runtime will be the first one to be started when cooling is needed. In the event of a fault or failure indication from any chiller set, the chiller set will be disabled and taken out of the duty cycle table until a fault has been rectified. The ability to manually take a chiller set out of the duty cycle table for maintenance purposes is also part of the control logic.
The control schematics are detailed below:
Secondary Pump Control Philosophy
A number of variable frequency-driven secondary pumps are deployed. These pumps are designed for a maximum of three of them running, with one standby. The secondary pumps are primarily controlled via a differential pressure sensor mounted in the secondary pump circuit to the buildings. There are a total number of buildings served by the secondary pumped circuit. Each building controller will interface with the ETS, which will monitor the status of the differential pressure sensor to ensure that a

minimum index differential pressure is being achieved. The BTU flow meter readings along with supply and return temperature sensors are used to monitor each building’s status. The BTU meter on the secondary circuit and the 102
differential pressure sensor, along with supply and return temperature sensors are used to calculate the secondary circuit pump speeds, in order to maintain a minimum flow and modulated to maintain the required differential pressure.
Climate Control Middle East November 2014
The usage of the secondary pumps is distributed in such a way that all the pumps are working at their most efficient. And by calculating runtime hours always working for approximately the same run time, it is ensured that after each duty cycle (1 - 3) the pump with the least amount of runtime will be the first one to be enabled when demand arises. These pumps receive the ‘start/stop’ command from the primary pump controller only if the hand-off-auto switches of all these pumps are in ‘auto’ position. The ‘run’ status and the ‘trip’ status of all the pumps are monitored via volt-free contacts from the motor control centres. The fault signal and the feedback signal
The usage of the chillers is distributed in such a way that all the chillers are working at their most efficient
from the VFD of the primary pumps are monitored. The sequence of operation of the secondary pumps is as follows: If the system demands a secondary pump to be enabled, a command is given from the secondary pump controller through the duty cycle calculation to enable the first pump. The pump speed is modulated to maintain a constant differential in the secondary circuit. The second secondary pump is enabled. If the capacity of one secondary pump is insufficient, then a third is enabled to maintain the differential pressure in the system. This sequence operates in reverse should the demand fall. Should a building differential pressure sensor detect a low differential
Table 1
pressure within a building, and a high ΔT, then the secondary circuit pump control would be overridden to modulate the pumps to
maintain the differential required for the particular building. A high level safety set point on the secondary header will limit pump speed.
The electricity consumption of the primary pumps is metered for energy consumption, efficiency analysis and diagnosis

Rental costs of temporary cooling plants
The rental costs for a cooling plant from a permanent supply are considerably more cost effective for the client as can be seen in Table 2. The table is based upon 800 RT, which is an extremely small system. However, should a client have a plant of 5,000 RT, then the savings on hire of the equipment alone is AED 315,000 per month. Thus, over a 12-month period, the saving would be AED 3.78M. On a larger system of 10,000 RT over a 12- month period, the saving would be AED 7.56M. A factor which must be considered is that the authority approval and procurement period for a
Table 2
permanent system requires three to four months from the date of award, whereas a temporary system can be mobilised and set to work in less than one month.
Running (fuel) costs of temporary cooling plants The running (fuel) costs for a cooling plant from
Table 3
104
Climate Control Middle East November 2014
a permanent supply are considerably more cost effective for the client. The annual cost of diesel for the temporary generator power source is AED 102.3M, as against the cost of power from the authorities for the next generation plant is AED 21.7M. Thus, the savings achieved in fuel alone is AED 80.6M. It should be noted
that this does not consider efficiency savings achieved through the automated controls, which may be a further 25%. It should also be noted that that the authorities will charge approximately AED 150,000 per MW of power, including supervision, connection and metering charges. For a 10,000
RT plant, there would be an electrical load of approximately 17MW. The authority fees, therefore, will be approximately AED 2.55M.
Maintenance costs of generators versus transformers
The maintenance costs for a cooling plant from a generator are considerably higher than that of a transformer. It should also be considered that a transformer has double the life span of a generator.
HESQ
A further advantage associated with a new generation temporary cooling plant is that the plant will be governed by the local authorities, and as such, design, procurement,
installation, testing and commissioning of the plant must be carried out in accordance with the relevant authority, which will result in a high-quality and safe endproduct.
• A safe system • A high-quality end-product • A more environmentally ‘green’ system • A highly cost-effective solution as demonstrated
in Table 3 (see left). Based on a 10,000 RT plant for a duration of 12 months, the savings to be enjoyed by the end-user could be in excess of AED 60 million.
Conclusion
The new generation temporary cooling plants are not suitable for all temporary cooling plants, ie, a small short-term contract. However, when a client requires temporary cooling, has a three to four-month lead in time, needs a plant in excess of 800 RT and a duration in excess of six months, the case study clearly demonstrates that a new generation temporary cooling plant would be a very feasible option providing clients with:

THE BSRIA REPORT ON ROOM AND PACKAGED AIR CONDITIONING IN THE UAE
No surprises in the package The BSRIA report on Room and Packaged Air Conditioning in the UAE reiterates the reality we have now come to accept – the economy is recovering slowly, with the results percolating down to the air conditioning sector, but it would be unwise to expect big surprises. The outlook for room and packaged air conditioning for 2014 reflects this. The long-term trend is towards splits, the report predicts.
T
he BSRIA report on Room and Packaged Air Conditioning in the UAE has been released recently. Prepared by David Garwood, and dated June 2014 and issued by BSRIA, the report takes into account the improved business confidence that became evident towards the end of 2012, with some of the construction projects being pushed through. This comes with a caveat, as these projects were typically the ones that had been left unfinished since the financial crisis. It will take some years for vacancy rates in the main UAE locations to decrease to healthier levels the report alerted, but conceded that recovery, although slow, is on its way.
The trend has been towards high wall units away from windows trade zone outside Dubai to the other Middle Eastern countries or use distributors to cover the region. International companies
The general outlook – cautious optimism Due to the mixed signals coming from the market, the report listed the following reasons for its cautious optimism: • Dubai represents a hub for most companies in the Middle East. A number of suppliers ship from the free 106

projects, there have been some announcements of new projects, but many are still on the drawing board. However, the economic situation in the UAE improved steadily throughout 2013, mainly from the global economic environment settling down. Businesses started to believe the worst was over. The economy was expected to grow, driven by on-going momentum in non-oil sectors, such as the tourism, hospitality and real estate segments, coupled with many businesses moving to the UAE due to regional instability elsewhere. This also witnessed a surge in tourism in Dubai. According to the International Momentary Fund, oil production growth could be limited by the ample supply in the global oil market. Real estate market is beginning to improve, with rent prices increasing following the increased demand from expatriates coming from other Middle East countries, plus an increasing national population. Rental price increases are expected to push up inflation slightly. Dependence on oil, a large expatriate workforce, and growing inflationary pressures are significant
long-term challenges, the extremely high growth rates seen in 2008 are not expected again, but with the development of nonhydrocarbon activities, the UAE economy is expected to continue a slow rebound.
• The hospitality and leisure sector is considered to be a potential sector for investment. Residential projects are also seen as a priority area for investment due to the rise in demand for residential units. The
demand for commercial and retail spaces was also reported to be on the increase. • The private sector is starting to recover in Dubai through foreign investment. The Dubai

government is looking to invest in infrastructure and petrochemical projects. Apart from tourists, there has been an increase in international travellers using Dubai as a stopgap destination. This has resulted in hotel occupancy going up, which has benefited the economy. • Construction firms have branched into new markets, focusing on public sector schemes and forming new alliances in a bid to win work in an increasingly competitive environment. A large number of construction projects are currently either at design stage or underway in the UAE, mostly driven by the infrastructure projects that are planned in Abu Dhabi. • The UAE is planning to
