mpower, the District Cooling services provider, has announced that it has begun commissioning the region’s first District Cooling plant built in line with green building principles. Touted as the fastest commissioning of a District Cooling facility of its size in the Middle East, the construction of the plant was reportedly completed in just over a year, and is said to include state-of-the-art infrastructure, such as pumps, chillers, water tanks, cooling towers and
office space. The plant, said Empower, is its second facility in the Business Bay area, and provides 45,000 Tonnes of Refrigeration (TR) of cooling services to developments in Dubai’s Business Bay, thus increasing the geographic scope of the company to include buildings from Sheikh Zayed Road to Al Khail Road. “The commissioning of the new Business Bay plant is a demonstration of how seriously Empower takes sustainability,” said Ahmad Bin Shafar, CEO of Empower. “The

facility has been planned according to international and regional benchmarks in sustainability – the design is in line with LEED building principles, as well as Dubai Executive Council’s directives on environmental sustainability.... This plant will be an integral part of a multi-facility District Cooling network in Business Bay. On completion, the Business Bay network will provide residential, retail and commercial real estate developments with up to 300,000 RT of cooling services.”
GBC, in a communiqué, has announced that it will be hosting the 3rd Annual EGBC Congress in Dubai from October 20-21. To be held under the patronage of H.E. Dr Abdullah Belhaif Al Nuaimi, Minister of Public Works, Emirates Green Building Council, the Congress will have “Sustainable Cities for the Future” as its theme, the communiqué added.
mpower, the District Cooling services provider, has announced a 9.4% leap of consumption of its services for the month of July, providing a total of 174.3 million refrigerating tonnes per hour (RTH), up from 159.2 million RTH for the same period last year. Empower highlighted that in January it acquired Palm District Cooling, leading it to more than double its portfolio from 400,000 TR of District Cooling capacity to one million tonnes TR. The company’s enlarged portfolio, it said, contributed to the rise in peak consumption, along with a surge in residential and commercial occupancy. “The month of July is usually the time of year that Empower experiences the highest demand for cooling services,” said Ahmad Bin Shafar, CEO, Empower. “We have been able to meet the demand of an expanding customer base because of the strategic nature of our networks and the hard work of our team.” Shafar termed the increase in consumption of its services an important indicator of Dubai’s economic health, with companies continuing their operations through the hotter months.
The EGBC, terming the event a landmark initiative dedicated to fostering industry dialogue and engaging stakeholders to influence sustainable practices in the built environment, claimed that it will provide a platform to discuss opportunities and challenges related to the role of cities and regions in catalysing and facilitating sustainable innovation, products, services, technologies and new business models.

‘LEED for Homes is the new paradigm’
KSA to see a wave of green building projects for individual homes
L
EED for individual villas is the new paradigm, according to Dubaiheadquartered Green Technologies. The company’s Managing Director, Mario Seneviratne said LEED for individual homes was the way forward in the residential sector and the route to a new wave of sustainability in the GCC. Seneviratne was speaking at an August 21 Business Lunch, in which Sanyog Rathod, the President and CEO of US-based Sol Design + Consulting was
the guest speaker. Seneviratne revealed how Green Technologies was involved in an initiative to usher in a new wave of green building projects in Saudi Arabia under the LEED for Homes programme of the US Green Building Council (USGBC). Sanyog, he added, would play a critical role in the initiative, providing the LEED Home expertise. According to Green Technologies, the LEED for Homes programme started in 2005 and was
, Yo u r t r u s t e d pa r t n e r f o r Yo u r engineering, energY and environment solutions
officially launched in 2008. In 2011, the LEED Homes international pilot programme was launched, making the programme applicable to projects outside of the USA. The scope of the programme includes single-family homes, low-rise buildings (three storeys or lower), midrise buildings (four storeys or higher), single-family production villa and gut rehab (retrofitting). In a traditional LEED green building project, which involves the owner, the design team and the construction team, the onus is on the design team to gather information and submit the required documents to the USGBC-GBCI, Green Technologies explained. The LEED for Homes programme follows a different process, simply because it typically involves a project containing a large number of housing units (for example, single-family villas), which means it becomes impractical for the USGBC-GBCI to verify the credentials of every unit. The LEED for Homes programme, hence, allows a green-rater (verifier), upon who would fall the responsibility of evaluating the designs of the units and reporting to the USGBC, Rathod said. “That way, the USGBC does not have to check, say, 300 units,” said Rathod. “Instead, it has the
simpler task of conducting random but sample checks.” In Saudi Arabia, Rathod’s firm, Sol Design, will be fulfilling the role of the verifier. Green Technologies will be playing the role of the LEED Consultant. In the US, incentives are reportedly available for individual green home projects. For instance, homes owners in Cincinnati, Ohio, can benefit from property tax abatement if their unit comes under the LEED for Homes programme. In a country like Saudi Arabia, though, the driving force would be a countrywide programme to reduce domestic energy consumption, said Seneviratne, adding that the Kingdom was aggressively pursuing an energy efficiency programme to ward off the potential of over-consumption of energy, with reference to production. Seneviratne expressed optimism over the LEED for Homes programme finding traction in the GCC, adding that there was ample evidence of a market shift towards green buildings, in general. “The world is moving from +30% electricity consumption over the baseline to -66% energy consumption, as is the case with the new DEWA Sustainable Building in Dubai,” Seneviratne said. “If you are not building green, you are catering for the dinosaurs.”

Pace of UAE construction sector set to accelerate
Renewed industry confidence spurs largest ever editions of The Big 5, Middle East Concrete and PMV Live this year, say organisers
A
ccording to a report released in April this year by consultancy, Ventures Middle East, entitled “Exploring UAE’s Strong Investment Environment”, new projects, combined with many previously stalled projects now forging ahead, will continue to bolster the 2013 upswing into 2014. The report has also stated that the UAE’s GDP for 2014 is set to grow at four per cent to reach USD 404 billion, fuelled by the construction sector upturn and support from the oil & gas sector. The report sets the value of the country’s building construction sector at almost 60% of the total projects in the construction industry, followed by infrastructure, oil & gas and power and water, with construction projects awarded in the UAE totalling USD 38 billion in 2013. This year, it is expected to reach USD 46 billion in awarded projects in the country. In line with the continued growth, the country’s infrastructure sector has also seen significant investment and development, particularly in roads and airports, the report revealed, and added that similarly, in Abu Dhabi, the AED10.8 billion Midfield Terminal Building project – a 700,000-square metre site with what is set to be the world’s largest baggage system – remains on schedule to open by July 2017.

nfrastructure will be a key focus for seminar sessions at this year’s Middle East Concrete and PMV Live exhibitions taking place at the Dubai World Trade Centre from November 17-20, co-located and running concurrently with The Big 5 International Building and Construction Show, organiser DMG Events has announced. Dubbing them pioneering shows, the organiser claimed that the niche construction events will bring together more than 355 exhibitors from over 32 countries with more than 20,000 international participants. During the first day, there will be a panel session, entitled “Market update and future forecast of the Middle East’s infrastructure sector”, that will look at the key issues the region has to overcome, DMG Events informed. New figures released by Ventures Onsite, a construction intelligence firm and intelligence partner of the twin events, show a dramatic increase in contract awards across the region in every country, except Saudi Arabia, DMG Events revealed, and gave the following details: • Infrastructure project awards across the GCC are forecast to exceed USD 86 billion in 2014 • Qatar is expected to award projects worth USD 26.2 billion compared with just USD 9.4 billion last year. • Kuwait is expected to

award USD 3.45 billion, almost 10 times the previous year. In the UAE, USD 15.18 billion will be awarded, almost five times the 2013 contracts Oman infrastructure awards are expected to reach USD 7.4 billion – up by USD 5.5 billion in 2013. Bahrain, which awarded USD 382 million last year, is expected to award USD 3.4 billion. Saudi Arabia’s forecast award of USD 29.34 billion – the highest in the region – represents a decrease year on year; however, last year’s total of USD 33.6 billion included the USD 22.5 billion Riyadh Metro project.
• Infrastructure projects make up 16% of the total construction value of the GCC projects, and rail projects, like the Riyadh Metro, are the main beneficiaries. • It is estimated that the rail sector is worth USD 200 billion as the six countries aim for an integrated GCCwide network by 2018. Being held against this scenario, Middle East Concrete and PMV Live exhibitions will prove to be the region’s most important meeting points for heavy construction machinery, plant equipment, commercial and construction vehicles, and concrete, DMG Events claimed.

Feras Shadid, a rail assurance and asset management consultant, who will be a panellist at the infrastructure seminar on the first day of the exhibitions, said: “Rail networks create a more sustainable society that is not dependent on one mode of transport for passengers and goods. Also, the environmental advantages of using railways have been documented extensively, and the rail projects will create a range of employment opportunities, including high-tech engineering positions.”

KEY INSIGHTS ON WHAT'S MAKING NEWS
‘Sustainability is on the rise’ Engi Jaber, Architect/Sustainability Programme Specialist, Dewan Architects & Engineers, will speak on Day Two of the Sustainable Design & Construction Conference, to be held on November 18-19, as part of this year’s The Big 5 Dubai. She will address such issues, as designing, constructing and operating sustainable buildings and master plans for infrastructure, cities and communities; regenerating existing facilities to meet new sustainability standards; and re-defining smart sustainable built environments. Jaber was part of the project team that delivered the Premier Inn Hotel in Abu Dhabi, the first hotel to receive a twoPearl Estidama certification in its category.
Why do you think it is important to take the time and energy required to give conference presentations? As someone who is dedicated to the cause of sustainability, it’s always a pleasure to raise awareness. Conferences are the best place to meet people who are likeminded and interested in the subject. They are there to understand more about sustainability in the region and learn what they can do to help their projects become sustainable. It is also about people getting to know our company and the efforts that we make in our projects. Since you first spoke about sustainability at a conference, have you seen an increase in audience knowledge? Yes. At my first conference, people were vague about sustainability. But with all the regulations that have come out over the last few years, it’s now a group of people who have become more aware. Nowadays, even if you get technical, people understand what you are talking about, and if they don’t, they come up afterwards and ask. How do you see the state of sustainable building? It’s growing positively, as people are becoming more aware. It started with Estidama as a mandatory requirement. On our first project, it was difficult to get everyone at the same table and satisfy them that, beyond it being mandatory, it is actually beneficial to create a green building.

Climate Control Middle East September 2014
The good thing is that the market started off with very little that was green, but now we find that we can actually get more products from within the region, rather than importing it, which saves on time and costs. When do you think it became possible to develop green buildings within a conventional budget? I think it was when people really understood the concept behind sustainability, rather than treating it as a set of add-on criteria. Of course, the availability of materials played a role, but it was mainly when people understood the concept of an integrated approach – how we can actually design and construct within a budget, rather than going through the conventional method of building, then doing value engineering. How have changes in the regulatory environment made the creation of sustainable projects, such as the Premier Inn possible? When you talk about sustainability, you get different opinions from key industry developers and decision makers – some proand some anti-sustainability – not because they don’t believe in its benefits, but because cost is the key driver. Therefore, when given the “option” whether to deliver a sustainable development or not, the tendency was to skip it. When Estidama and other regulatory authorities mandated sustainability, everyone was forced to deliver green buildings. Now we get contractors who are willing to do more than their scope in order to achieve a higher level rating. Developers want
to exceed the minimum requirements, because they are more educated about sustainability and have witnessed the savings and returns on their investment. Sustainability is on the rise, not because of regulatory compliance, but because people are convinced that it is well worth their investment. How has the supplier sector responded to the change? Since all projects have to meet the regulations, the supply market expanded, and a new segment of green product lines is now available. I recall our first Estidama project, where we, the consultant, were asking for products that the suppliers just couldn’t deliver easily. Now, especially with strides made by large construction exhibitions, such as The Big 5 Show to bring more sustainable products into the market, we can practically call up any supplier, and they would be able to communicate on the same level and provide you with materials that meet your needs, if not exceed them. Why do you think people are looking to exceed the regulatory minimums? Some are boldly trying to state that they are developing green projects, rather than being interested in sustainability. But the tendency is heading more towards people who are actually interested in sustainable projects and what they do for the environment. These are the ones who are really committed. They are the ones who come in wanting more than the mandatory requirement. Even if they don’t go for certification, they want a green building for operational reasons: healthy environment, efficient systems, et cetera. How do you think things will change over the coming years? Because people are becoming more open to the idea of sustainability, we will find a lot of the optional credits will become mandatory. I believe we will see more requirements and the regulations will become more stringent. Since we were able to achieve Estidama – which is tougher than LEED on energy and water consumption – people are realising that, even if regulatory requirements are increased, they will still be eager to do it, because at the end of the day, everyone benefits.

‘The cranes are once again moving’ Ziad Sharqawi is a senior architect with the UAE’s largest construction firm, Arabtec. With more than decade of experience in the industry behind him, he has been involved with The Big 5 Dubai as a visitor, exhibitor and participant since 2001. He currently sits on The Big 5 Dubai Advisory Board, a group of industry professionals that provide insight and guidance to the continuous development of the show to meet the needs of its visitors.
How long have you been involved with The Big 5? Back in 2001, I was with a company called White Aluminium, an architectural aluminium manufacturer and fabricator, and we had a stand at the show. It was an event where we met some interesting people and did some deals, too, as The Big 5 helped us to generate new business. The experience we had was positive, and The Big 5 has stayed on my radar screen ever since. How do you engage with the event now? I have been a Senior Architect with Arabtec Construction for the last seven years. I look after the shop drawings for the company and manage the approval process, working with the consultants on the projects, plus follow up with our site teams who do the work. As a visitor for Arabtec, I always find it useful to be at the show. Since the show is massive, we usually don’t have enough time, so I prefer to go and see specific people or companies, so I can make the best use of the time I do have. We use the opportunity of the show to communicate with other people for our business. We see the technology that some of the best companies in the world have to offer. It is great to see all of this innovation in one place – under one umbrella – from all over the world. How are you finding business in the UAE market?
There will be plenty of competition for building supplies, and it will be clear to everyone that a second boom is on the way
working hard. Things are getting off to a good start. Right now, I’m looking after a number of villa projects in Abu Dhabi and Dubai, including a 1,240-villa development in Al Barsha, which is nearing completion. So, the market is active in the residential sector again and my company is also working on a number of commercial towers. How do you think things will shape up towards the end of the year? I think things will start happening after September on a huge scale. There will be plenty of competition for building supplies, and it will be clear to everyone that a second boom is on the way. You are on The Big 5 Advisory Board. What is your role? Advisory Board members attend regular meetings and discuss their views of the construction marketplace and most recent happenings. We, then, focus on how we can develop The Big 5 for the better. As a result of feedback from the board, the organisers of The Big 5 – dmg events have implemented changes to improve the show experience for visitors. These changes have included the introduction of a mobile app to help plan your visit and the segregation of suppliers into sections based on the type of products they provide. Two-way feedback between the board and organisers is vital: It’s important to serve the needs of The Big 5 exhibitors and visitors. How do you think architects, in particular, can benefit from attending The Big 5? Architects can get a lot of benefits at The Big 5. Firstly, they can keep in touch with the latest technology used all over the world and see it all in one place. They also have the opportunity to attend events within the show to hear from pioneer architects, engineers and leading consultants or contractors. Doing so helps them add to their experience and motivates them to go out and gain more. It can also give them creative new ideas for the use of new techniques and materials.
You can see now that the market is starting to move faster. Many projects that were stopped for one or two years have now restarted; the cranes are once again moving, and you can see the labour crews are
Any special plans for you at this year’s Big 5 Dubai show? Continuing professional education is important, and I plan to attend the twoday Sustainable Design & Construction Conference and some of the certified educational workshops.

THE real cost of
economic development
Kuwait’s economic growth is heavily anchored on to industries that are observed to consume the most energy. While it is currently enjoying a high level of economic buoyancy, the frenetic pace of business and social activities is taking its toll on the country’s energy reserves. We have the report.

Kuwait will need to use 20% of its oil production capacity just to be able to meet the country’s energy demand within four years
Focus on renewables: Is it plausible?
Kuwait’s production of primary energy is largely dependent on oil and natural gas – both finite sources. In addition to energy generation, oil and natural gas play a major role in the economy of Kuwait, as they are part of the country’s main sources of revenue. Now, the conundrum is that these resources are non-renewable, and as the reserves continue to 48
recede, both Kuwait’s ability to produce power for its industries and the country’s economic buoyancy may be impeded. In recognition of this future scenario, Kuwait took a proactive step and launched a renewable energy programme as early as in 1975. According to the Kuwait Institute for Scientific Research (KISR), between 1985 and 1988, Kuwait heavily invested in solar and wind energy applications. However, the
Climate Control Middle East September 2014
country found the thenexisting technologies not viable, largely owing to high initial cost, lack of efficiency and high maintenance costs. Thus, in 1988, the renewable energy programme was discontinued.
Renewables: Are they aligned with the country’s needs?
Kuwait has one of the highest energy consumption per capita rates in the world, with an average Kuwaiti said to be
using 22 times more resources than the country offers per person. In an effort to boost the country’s energy reserves and to avert the grim scenario described above, Kuwait has set a target to generate 15% of its electricity from renewable sources by 2030. With the technological advances in recent years, renewable energy systems have proven to be more cost-effective, efficient and reliable than before. With considerable increase in the prices of fossil fuels, both standalone and grid connected renewable energy systems have become more advantageous in terms of cost. In addition, renewable energy facilities have also been observed to produce significantly lower greenhouse gas emissions. This initiative is clearly intended to veer away from energy generation by burning fossil fuel, because, according to experts, Kuwait will need to use 20% of its oil production capacity just to be able to meet the country’s energy demands within four years. As Kuwait is an oil-dependent economy, the above-mentioned consumption pattern is, thus, deemed unsustainable. But, are renewable energy sources, like solar and wind, sustainable in Kuwait? KISR believes so. During the summer months, when electricity consumption spikes in Kuwait, with HVAC equipment in full blast, the abundance of intense sunshine guarantees maximum power availability from solar power generation sources. Moreover, Kuwait has a wealth of desert land where solar power facilities can be installed. An area of five square kilometres (0.03% of the land area of Kuwait) is said to be adequate to generate 500 MW of solar power. The western and the southern regions of Kuwait are perceived to be more suitable for wind power
generation. According to KISR, Al Wafra and Al Taweel may be the best locations. In addition to boosting the national power reserves to meet peak demands, wind electricity generation may represent an economical choice at less than 40 fils/kWh.
Kuwait’s energy situation: What lies ahead?
Harnessing the potential of alternative power sources is not the be-all and end-all of Kuwait’s perceived energy challenges. While renewable energy sources are gradually being developed, stabilised and optimised, their present penetration level in the country makes it unrealistic for them to become the main source of electrical power in Kuwait. Renewable energy technologies are fast gaining traction, but there are still several obstacles to be addressed, including: • Observed deficiency in smart electrical grid • Observed inadequacy of codes and standards governing renewable energy sources • Higher capital cost • Perceived insufficiency of publicprivate partnership, leading to minimal financing • Inadequacy of available skills and expertise • Lack of information transfer and consumer awareness • Fear of change
the highest electricity consumption is ascribed to HVAC equipment, the onus is on manufacturers and consultants to be more proactive, and research and develop systems that optimise energy performance. In this regard, industry professionals need be trained and be abreast with the most updated energy efficiency best practices in order to maximise the energy-saving potential of the latest technologies on offer.
Conclusion
Generating electrical power from
renewable sources has an enormous potential to ensure the sustainability and viability of Kuwait’s natural gas resources, which are critical not only to the country’s industries but also to its economy. While new sources are being exploited, citizens should not forget that they also have a fundamental role in maintaining a healthy energy mix. With stringent energy efficiency regulations and vigilance in opting to purchase and use power-efficient equipment, Kuwait’s economic and social growth can be assured.
At present, there is still a pressing need to promote energy efficiency in all types of buildings, particularly in residential and commercial units. As

The Kuwait experience Dr Adel Husain of the Kuwait Institute for Scientific Research (KISR), in an exclusive interview with Climate Control Middle East, shared significant information on Kuwait’s ongoing drive to reduce energy consumption and promote the generation of renewable energy. Highlights….
“I
n the aftermath of the Iraqi invasion, Kuwait sustained excessive amounts of fume from over 600 burning oil wells, which has affected the climatic conditions. The smoke plumes acted as a ‘shield’ against the UV radiation and the warmer temperature arriving from the sun. Owing to these climatic conditions, Kuwait witnessed colder winters and hotter summers. From this experience, Kuwait recognised the consequences of climate change and its effects on the daily lives of the residents. Such events increased the awareness of climate change in the country and drove Kuwait to take a closer look at the impacts of such environmental tragedy. “Most of the residential units in Kuwait rely on central air conditioning. Most of the electrical power generated in Kuwait is used for AC (70%). The rate of increase for power demand in the country is around six to seven per cent annually, which prompts power plants to generate the extra electricity required. “In light of the steep rise in power requirements in the country, the Ministry of Electricity and Water is now promoting the concept of reducing the energy waste by updating the Energy Code. Now, the GCC is planning to issue the GCC Code of Practice for buildings, which covers the use of energy in different contexts. “The Government is promoting the reduction of energy usage, particularly during the summer months. The Government is looking at peak load shaving by utilising other sources of energy and abolishing the use heavy crude oil. It is also capitalising on renewable sources of energy and green building technology through integrated building design. Moreover, KISR has participated in providing a couple of studies related to integrated building design in order to save energy and promote a cleaner environment.”

Re-engineering one’s concept of air filtration International air filtration consultant, Dr Iyad Al-Attar, who is also a long-time columnist in Climate Control Middle East, believes that a paradigm shift in air filter selection is needed in order to maximise the potential of the latest filtration innovations
T
he increasing public concern regarding Indoor Air Quality in residential and commercial buildings has led to major developments in highefficiency air filters. Air filters are an integral part of HVAC systems in buildings, and are essential components of clean rooms and gas turbines’ air intakes. A large mass of clean air must be supplied to operate a gas turbine in order to generate energy for our buildings, which in turn will be used to introduce clean air to indoor spaces. However, be it for HVAC or power generation, air filtration remains a common denominator in the mathematics of designers.
winds in desert regions and volcanic events are natural phenomena that cause high airborne dust concentrations. Therefore, weather conditions; the natural environment and human activities can cause
It is not only dust Although our mind immediately thinks of Sahara dust when we think of air filtration, it is important to realise that not all dusts arise from human activity. High

humid areas like South East Asia?
Re-engineering our minds Great emphasis has been placed on how innovative air filtration technology should be deployed to counter contaminants. However, the emergence of filtration technologies as pollutionsavers and our sole reliance on them to provide clean air are simply not enough. So, before we rush to re-engineer entire HVAC systems’ filter selection criteria, I believe before we re-engineer air filtration technologies, we truly need to re-engineer our minds to regard it as a critical and essential element in our HVAC and GT systems. Air filtration is a complex process as it stands. However, we seem to add to its complexity by adopting certain undesirable practices in terms of installation and maintenance. One of the most common practices, which we need to unlearn, is regenerating disposal filters (Figure 3). Truly, there are several parameters we would have to consider to make an educated selection of air filters for different applications. However, when the language spoken on the site differs from that spoken in the meeting room while acquiring filters, blaming fingers will get lost in between. The complex dynamics of air filtration requires a comprehensive understanding in order to engineer it towards a safe delivery of clean air to the indoor space. The preventative nature of air filtration dictates its influence on the performance of HVAC systems. Isn’t it time we bring it to the spotlight? Air filtration is a microscopic process, which signifies the importance of testing and quality control. Therefore, government involvement is paramount to regulate its rules and practices. 52
Figures 2: Corroded aluminum pre filter used in air handling units
Figure 3: Damaged minipleat filter after regenerating (cleaning by air or water) Conventional filtration measures are yesterday’s tools. Therefore, we need to face the environmental challenges with highly advanced technologies. Similar to other areas of filtration technology, understanding air filters and their correct application is a complex one. Appropriate air filter selection helps users avoid some of the costly mistakes that lie in ambush for those less experienced in the techniques of filtration. Professional filtration and maintenance practices will prove invaluable for people engaged in HVAC and GT fields, industrial hygiene, air pollution control, or environmental science, who need to have a practical understanding of the practice of their profession in relation to the evaluation or control of airborne pollutants. I believe we ought to lead a change if we want to ever meet this goal. It is
Climate Control Middle East September 2014
not enough for us to claim that clean air is one of our top priorities. It requires a thoughtful approach that takes into account the possibility that air filtration can fulfill the goal. Climate change and sandstorms burden our air filters with pollutants, which again brings to the forefront the need and willingness to achieve the objective of better IEQ. However, this would require a strong environmental policy, emission reduction and professional air filtration, in order to deal with inevitable pollutants that invade our indoor space. People will certainly want to see decision-makers take on these issues in an aggressive manner.
Post-scriptum: Sandstorms Sandstorm is commonly experienced in Kuwait. During a sand-dust storm period, the
strong wind raises rough sand and fine particles, which turn into a sandstorm or a floating dust storm after long-distance transfer. Among them, particles with a diameter smaller than 10μm (PM10) account for most of the storm. A sandstorm could also carry heavy metal, bacteria, virus and poisonous minerals, which may be inhaled by people, resulting in great negative impact on human health. Sandstorms assault our indoor spaces and add to the complexity of the filter performance deviation problem. They bring higher concentrations of suspended atmospheric particles that affect nearly all human and industrial activities. To effectively combat this, appropriate filter selection should be made and proper maintenance measures exercised throughout the year to the required professional degree, so that air filters can protect human beings and industrial applications from pollutants suspended in the air stream. All these contaminants, which can come from parking areas, vehicle emissions, ambient traffic and construction activities, challenge the air filters installed in the building’s HVAC system, and their excessive concentrations alter the dynamic performance of filters.

COLD CHAIN
Negotiating lowGWP alternatives for the cold chain industry With the HVACR industry going through a challenging period of transition in refrigerants, the cold chain stakeholders need certainty for their investments in R&D and equipment, says Torben FunderKristensen. He believes that affordability, energy efficiency and safety will help constitute the sustainability triangle to help establish parameters to adopt low-GWP solutions.
T
he third big refrigerant transformation since the dawn of refrigeration is gradually developing, as a result of legislative measures and technology development of viable lowGWP solutions, as visualised in figure 1. Legislation with caps on consumption and GWP–linked taxation make the continuing use of the old high-GWP HFCs difficult. Especially, the EU has taken a major step with the adoption of the F-gas regulation, and other regions are likely to follow with similar or other measures, as seen in Figure 2. Low-GWP refrigerants, on the other hand, are favoured by incentives and by the fact that they are in basic compliance with intentions behind the legislation. It will eventually become difficult to obtain old refrigerants.

However, it is difficult to predict when the market will actually face the shortage.
Affordability, energy efficiency and safety
The cold chain stakeholders need certainty for their investments in R&D and equipment. Especially in the times where the legislation and standards change, it is important to observe the balance of market and legislative forces to identify the barriers for transformation and transition. Legislation could impose tough measures on the industry that may not be easy to comply with due to lack of requisite technical skill of field technicians or inadequate downstream legislation on energy efficiency or safety building codes. The ability of the market to adopt low-GWP refrigerants, of which natural refrigerants constitute a
and comes first. Competent use of established safety standards like ISO 5149, EN378 and IIAR guidelines will ensure efficient and safe use. The recently updated ISO 5149 now opens up for use flammable and mildly flammable refrigerants for stationary equipment. While ammonia has been in the market for decades, with very high charge amounts, hydrocarbons are limited to smaller charges. Larger pilot installations exist, and have proven highly efficient. But its widespread use has been limited due to safety concerns. Charges up to 150g fulfil the requirements for many hermetically sealed commercial applications, such as vending machines, bottle coolers and ice cube machines. AES parameters

The recently updated ISO 5149 now opens up for use flammable and mildly flammable refrigerants for stationary equipment major part, is becoming a crucial parameter for a real breakthrough of natural refrigerants. Cold chain is affected by the issue as much as other applications. AES – Affordability, Energy efficiency and Safety constitute the sustainability triangle which describes the parameters to be
aligned and balanced to adopt sustainable low-GWP solutions. In table 1, from farm to fork, the sustainable low-GWP refrigerants are listed based on the three AES parameters. A clear picture emerges when we consider the low- and high-ambient conditions. For low-ambient temperatures, a portfolio of low-GWP refrigerants and components are available today. Many solutions are actually showing better AES performance than the old HFC solutions. It needs to be remembered that the biggest challenges appear when we look at it in the context of high-ambient temperatures. However, solutions are available or will become available.

are suitable for such small applications.
Refrigerants and transportation
Transport refrigeration needs safe refrigerants for many reasons. The location of vehicles and containers are often difficult to track, and the charges of these systems are too small to be under the general accepted minimum charge limit of 150g. The system mobility means that the location becomes undefined, and service may also be performed under varying conditions. Hydrocarbon technologies may be efficient and affordable but do not appear to constitute a safe solution yet for trucks, trailers and vans if the refrigerant charge becomes high. A variety of new synthetic refrigerants have been developed with nonflammable properties or only mildly flammable properties. Even though many of these refrigerants may not be categorised as low GWP, they still have much lower GWP than the incumbent HFCs, like R404A.
Food retail
Stationary multipack systems for food retail do have good opportunities of lowering the total GWP impact of retail stores. Traditional food retail stores have

large charges, and this disqualifies hydrocarbons. Hydrocarbons, on the other hand, can be used for selfcontained units connected to a circulating heat-carrying fluid in the store. However, the systems must overcome several heat exchanger barriers impacting its efficiency. The development of CO2 solutions has been going on for more than a decade, and today, they have become the preferred choice in lowambient regions. Work is in progress to make them suitable for high-ambient temperatures. However, indirect and cascade systems are suitable in the GCC countries. It seems clear that the EU F-gas regulation will push the southern EU markets in the direction of indirect CO2 systems with an efficient chiller on top of the systems. Whether this
chiller should use ammonia, a new type of low GWP blend or a traditional HFC, such as R134a is not so important. Indirect CO2 systems are very efficient. They use a CO2 pump for circulating the liquid CO2 in the system. However, special care must be taken to ensure the protection of pumps against two-phase flows. These systems are expected to mature in the next few years.
The importance of timing, speed and education
The biggest issue in the coming years will be the timing and speed of the transition to low-GWP refrigerants. Even if new technologies become affordable and efficient, older systems still in use could create an as yet unforeseen complexity. In this regard, education of service workforce is a must, and the industry has already started addressing the issue. The industrial regional organisations now have a good opportunity to help and steer initiatives directly targeting the specific regional challenges.
Conclusion
Low-GWP refrigerants are on the global agenda.

Climate Control Middle East September 2014
During the next few years, a gradual transition will take place and create a state of flux in the market. A strategic decision for the future safeguarding of the industry investments seems the best solution to steer the journey towards longterm sustainable solutions. These solutions addressing affordability, environmental concerns and safety are partly available today, especially for industrial, food retail and light commercial applications. The biggest challenge of the transition is in the area of competence development and educating the market and service technicians.

SMART CITY
Sheikh Zayed Road, Dubai, UAE
How to build a smart city from the ground up Wi-Fi connectivity will be the key enabler for procurement, logistics and workforce planning at the construction phase, believes Wesam AlAssaf, an IT industry expert with experience in wireless technologies, and enumerates ways of achieving this. He predicts that smart construction will usher in a smart city era in the Middle East.
T
he Middle East is all abuzz with excitement about “Smart Cities”, and rightly so. Economic, social and technological factors have converged to make the region ready for widespread smart city developments.

Masdar City in Abu Dhabi; the recent announcement of strategic plans to transform Dubai into a smart city by His Highness Sheikh Mohammed bin Rashid Al Maktoum, the Prime Minister of the UAE and the Ruler of Dubai; six greenfield economic cities in Saudi Arabia; and Lusail’s Smart
Climate Control Middle East September 2014
and Sustainable City, Pearl Qatar and Energy City in Qatar are examples of the numerous initiatives that have already gained solid backing from respective local governments. As the Middle East ushers in this new era of advancement, much has been predicted and
promised about the integration of ICT in every aspect of the completed city developments. There is, however, no reason why the benefits of technology cannot be leveraged at an earlier stage – at the construction phase itself. In the GCC, there are around USD 3.45 trillion worth of projects that are in the design, bid or construction stage until 2025. So, clearly, employing technology to increase efficiency during construction could go a long way in streamlining operations and cutting costs. The computing capabilities of mobile devices have advanced to a level that has made them capable of aiding the planning, designing and building phases. But turning mobility into an effective tool requires not only computing power but also connectivity. However, at job-sites, wired connections are not feasible and cellular networks are not always available. A strong case can, therefore, be made for developers to utilise Wi-Fi solutions. These are not only easy to install and manage but are now also affordable and rugged enough to see deployment in harsh construction environments.
Facilitating workflow It isn’t uncommon for construction workers to still rely on paper-based documentation. Besides being cumbersome to transport and maintain, these documents need to be regularly updated, oftentimes at the site itself. With the introduction of tablet devices, mobile project management has emerged as a worthy replacement to age-old methods. Coupled with the broad ecosystem of feature-rich mobile applications and the ability to draw from vast amounts of remotely stored
data and “cloud” services, these devices are capable of granting contractors, engineers and supervisors access to blueprints, schematics and other vital documents. Moreover, with the ability to instantly push updates to all members working on the project, mobile computing devices can aid collaboration and revolutionise the building information modelling (BIM) process in real-time. With site-wide high-speed wireless connectivity for all the mobile devices, workers gain the ability to transfer high volumes of data back and forth between not only each other but also the HQ. This significantly streamlines communication while cutting costs and improving
Mobile computing devices can aid collaboration and revolutionise the building information modelling process in realtime
operational efficiencies. This could also bear attractive “green” side effects, as staff members no longer have to make regular trips to and from HQ.
Enabling asset tracking and better inventory
At job sites, company assets are a major investment and the progress of construction is heavily reliant on their functionality. Heavyequipment, such as cranes, bobcats and cement mixers are often required to be left on site overnight. This makes them prime targets of theft. Asset tracking technologies help monitor such equipment in remote locations and automatically detect and report suspicious

behaviour. These systems can also determine utilisation of expensive equipment and, thereby, help supervisors determine if it is being over or underutilised. Developers can also benefit from automated maintenance schedules, logs and reports. The availability of cheap and easy-to-use RFID (Radio Frequency Identification) technology has made possible the automation of inventory management. By knowing in advance which materials are soon to run out, construction companies can anticipate and avoid material shortages, thus eliminating losses in productivity. All these systems can only be deployed upon a robust Wi-Fi platform. Connectivity is, thus, becoming essential

Site security
Another vital area of a construction site where mobile technology can be applied is in video surveillance. Not only does this enable better collaboration and remote supervision, it is also essential to site security. High-speed connectivity for robust and cost-effective camera equipment can mean the ready availability of high-definition video, making both identification and collaboration easier. These video systems are also a key part of asset, tracking systems.
Assessing Wi-Fi solutions for the construction site
The challenge for the developer is to find a robust enterprise-class WLAN that is affordable in terms of the capital expense and operational overhead. While construction companies may be staffed with IT-savvy professionals at their headquarters, they have limited resources and RF expertise at remote locations. Consequently, they must utilise mobility solutions that are simple to set up, highly reliable, and can be managed centrally. While being portable enough to be transposed from one site to another, these systems must also offer enterprise-grade WLAN functionality. In line with keeping things simple, developers should also consider investing in controller-less “instant” WLAN solutions. These solutions utilise a virtual controller on access points to deliver controller-like features, including RF management and rolebased access control. As construction integrates more deeply with IT, network

Mobile computing devices can aid collaboration and revolutionise the building information modelling process in realtime uptime will become an increasingly important factor. It is, therefore, prudent to invest in network management tools, which can prove
Climate Control Middle East September 2014
invaluable in providing maximum network availability. Software that periodically backs up all device configurations on the network is simple but extremely useful. Since most construction sites don’t have copper or fibre cabling installed, and 3G/4G network coverage may not be up to the mark on location, developers can consider another alternative for their connectivity needs: They can partner with mobile operators who have a Wi-Fi offload strategy in place. In this case, they must look for a service provider whose solution is based on the new 802.11ac wireless standard, as this delivers gigabit Wi-Fi combined with the device density and application intelligence required by today’s Wi-Fi networks. Finally, developers must also invest in training personnel to utilise newly
deployed technologies. To ensure that the smooth transition from traditional methods to the modern mobile construction site, it is best to ensure that all team members are wellversed in and comfortable with all aspects of mobile technology. Once this has been achieved, “smart construction” will usher in the era of the “smart city”.

case-inpoint COOLING TOWERS
Cooling tower filtration – Flushing out the problem Claiming that the largest entertainment complex in the Southern Hemisphere improved cooling tower filtration and reduced maintenance and treatment costs, Glenn Dobbs and Roy McDougall present the case study and describe an enduser’s experience with multiple filtration technologies and their inherent advantages and disadvantages in their cooling tower systems.
Introduction
Keeping an open recirculation cooling water system: 1. Assists in maintaining heat transfer efficiency (0.025 mm of fouling equates to 10% reduction in cooling efficiencies1) 2. Reduces maintenance costs 3. Enhances the effectiveness of the water treatment programme 4. Collectively contributes to reduced costs and increased cooling tower system life.
The background
A patented self-cleaning screen filtration technology was supplied by VAF 70
Climate Control Middle East September 2014
Filtration Systems from the United States and was installed and commissioned by Hydrochem of Australia in 2013 at a major entertainment complex in Australia. VAF’s V-Series filters were supplied to replace three other types of filtration technologies serving 10 individual cooling tower systems. The older filtration technologies were not meeting the end-user’s strict Key Performance Indicators for cleanliness, and subsequently, the cooling systems required an unacceptably high frequency of manual cleaning. The end-user, therefore, chose to install a newer filter
technology to minimise problems associated with the older technologies. The replaced technologies included deep bed media, centrifugal separators and piston-operated self-cleaning screen filters. The following describes each installation, the technologies installed and the end-user's experiences with each.
ASHRAE states that “filtration”, not separation, is the method by which the very small and low density organic particles found in cooling towers are removed
The solution
The media filters were replaced with two VAF V-250 filters, which are operating and maintaining the cooling tower basins in a clean state, while removing the residual media from the system. Deep bed or sand media filters typically require a relatively large volume of water to backflush the media of contaminant trapped within. While a sand media system requires 1,200 litres of waste to backflush, the equivalent size of VAF’s self-cleaning
screen filter uses only 30 litres to backflush. Backflushing sand media takes full flow for at least three to five minutes, and the tank being flushed must be completely off line during the backflush process. Sand media can remove most particulates that are 10 microns and larger. However, it is difficult to backflush heavy particles (such as dirt, sand or calcium carbonate) collected from the tower without losing some of the media during each flush. Therefore, expensive periodic
The challenge
A hotel building in the complex had a cooling plant consisting of four common cooling towers with 30,000 litres total system volume. These were originally fitted with six deep bed media filter units that operated for approximately two years. In that time, the systems maintained the cooling towers in a clean state. However, they were found to require very large amounts of water for backflushing, which caused the cooling tower system to lose the majority of chemical treatment every time the filters were backflushed. The media filters were then reconfigured to utilise two filters per week on a rotating basis to minimise the water losses. However, excessive water loss through backflushing was still found to be a problem. In addition to the water loss, a number of the media vessels’ control valves failed and allowed large volumes of media into the cooling system, damaging the chiller system’s VSDs (variable speed drives) and fouling the condensers. Also, the required periodic replacement of media was very expensive.

case-inpoint COOLING TOWERS replacement of the media is required. Sand media is excellent for removing organic particulate including algae and sediment from the water and retaining those particles in the media. It has been shown by the EPA that sand media filtration on cooling towers and hot tubs provides an excellent habitat for bacteria, such as Legionella, since the organics combined with the sedimentation held within the media are the major source of nutrients for Legionella2. Centrifugal sand separators: A recent expansion with the installation of a new chiller plant included eight additional common cooling towers with 100,000 litres total system volume. These were originally fitted with two large centrifugal separators. The separators operated for several years, and were found to leave the basins with at least three to 10 centimetres of silt and organic matter build-up across the cooling tower basin floors between the cooling tower cleaning that was conducted every two months. The chiller VSDs were again affected by unfiltered debris in the system with strainers blocking up and causing overheating issues. The VSDs themselves required annual chemical cleaning to remove fouling that had built up, stopping effective heat transfer. The centrifugal separators were replaced with two VAF V-500 filters, which are effectively maintaining the cooling tower basins in a clean state. Centrifugal sand separators are primarily selected based on the fact that the technology is the least expensive. By definition, centrifugal sand separators (or hydrocyclones) are not filters since filtration is defined as “the process whereby a fluid passes through a surface or depth media”. They are 72
The piston filters have now been replaced with five stainless steel VAF V-250 filters which are maintaining the cooling towers in a clean state Figure 1: The deep bed sand media installation

Figure 3: The centrifugal sand separator installation

“separators” in that they utilise centrifugal forces by spinning the water to separate heavier particulate from water. Centrifugal “sand” separators only remove particles that have a specific gravity significantly greater than water and are larger than 70 microns3. Any particles that are organic or lighter than water, or any particles smaller than 70 microns, which remain as sedimentation, will not be removed. It has been clearly stated within ASHRAE
publications that centrifugal separation technologies are not appropriate for cooling tower filtration3. ASHRAE4 and the EPA2 have both stated that the organic particulates, such as algae, combined with the sedimentation that remain in the cooling tower basin after centrifugal separation provide an ideal habitat for bacterial growth, such as Legionella. ASHRAE4 states that “filtration�, not separation, is the method by which the very small and low density organic particles found in cooling towers are removed. Centrifugal separators are cleaned either by purging the particle collection chamber or by allowing a continuous small flow from the collection chamber to a drain. Centrifugal separators are often a part of other filtration systems that more reliably remove smaller and lighter particles. In those cases, the separator removes the larger and heavier particles, while the filters remove the remaining particulates that pass through the separator.

case-inpoint COOLING TOWERS Piston-operated selfcleaning screen filter: The original cooling water plant comprised 10 cooling towers in a common single basin system of 120,000 litres total system volume. These were initially fitted with five piston-operated self-cleaning screen filters. They were operated for a number of years but found to not maintain the cooling tower basins in a sufficiently clean state, with frequent issues of filter failures and excessive backflushing occurring. Also, the filter bodies were constructed of mild steel and had corroded from the cooling towers’ water treatment chemicals. The filters were eventually switched off, as they failed and were deemed not worth repairing. The piston filters have now been replaced with five stainless steel VAF V-250 filters, which are maintaining the cooling towers in a clean state and will never corrode. Another hotel complex cooling plant comprised one main system of three common dual-cell cooling towers of 30,000 litres of total system volume. These were fitted with one piston-operated self-cleaning screen filter system. The filter suffered frequent uncontrolled backflushing and blockages. The very large amounts of water for backflushing caused the cooling tower system to lose the majority of chemical treatment, and in warmer months, had caused the cooling towers to run dry, as the makeup supply could not deal with both the evaporation and backflush. When this happened, maintenance staff had to re-fill the towers with a hose, but not before it had caused temperature issues throughout the hotel. The piston filter was replaced with a VAF V-500 filter system. The cooling towers are now being maintained in a clean 74

state with minimal water consumption. Piston-operated selfcleaning screen filters have been around for more than 50 years, and were originally created for low-pressure irrigation applications. There are several types of selfcleaning screen filters that only differ in the mechanism used to clean the screens. Piston-operated self-cleaning screen filters utilise a suction nozzle system that is common on most automatic self-cleaning screen filters. In a piston-operated selfcleaning screen filter, the nozzles are rotated over the screen filtering element using a water motor with line pressure, and then the nozzles are moved along the screen length with a piston. Since the rotational movement of the nozzles is not directly related to the longitudinal movement of the nozzles
since it is only a small portion of the cooling towers’ blowdown requirements5.
along the screen, pistonoperated self-cleaning screen filters have the inherent problem of not always cleaning the entire screen area. This problem reduces the piston filter’s capacity to keep up with the dirt load it is filtering, which results in higher flush waste and, hence, excessive chemical losses. Also, the hydraulic controls for a piston filter are relatively complex and are inherently problematic, as they can easily empty a cooling tower basin, should the unit fail in the open position. Piston-operated screen filters are also known as “hydraulic” filters and are the lowest cost option for an automatic self-cleaning screen technology.
V-Series automatic screen filters, the end-user has seen the benefits of improved heat transfer efficiency, less chemical usage and improved chemical treatment effectiveness for bacterial and corrosion control. The filters remove all particulates down to 10 microns in size from the water the first time the water passes through the screen. Sediment and algae are retained on the screen for a very short time, so there is no contribution to bacterial growth on the screen. This technology uses only a few litres of water during each flushing cycle, resulting in the least flush waste in the industry.
The result and other positive outcomes
Automatic self-cleaning screen technologies provide uninterrupted screen filtration during the screen cleaning process, thereby requiring only a single filter for continuous filtration. The new patented V-Series filters installed for this enduser differ from the pistonoperated screen filters in that the rotation of the nozzles is provided by a water motor using system line pressure, and it rotates on a screw, such that 100% of the screen filtering element is cleaned bi-directionally at least four times with each cleaning cycle. This results in a very
After installing the “newer” patented V-Series automatic self-cleaning screen filters, the end-user is extremely satisfied with the improvement in their cooling tower systems’ cleanliness. This has resulted in a reduction of cooling tower cleaning frequency from six times per year to the minimum Australian standard requirements of two times per year. This reduction in cleaning frequency has also resulted in substantial savings in maintenance costs. By replacing the older technologies with VAF’s

chilled water supply systems at a reasonable cost. Method employed: It was determined that the best solution to clean up the large volume of chilled water loop, while keeping within a tight budget, would require a 300 gpm Vortisand crossflow microsand filter that provided submicron filtration and high-quality water. The Vortisand system replaced a traditional sand filter that claimed 5-micron capability. This was because a standard laser particle distribution analysis illustrated that 80% of the TSS were less than five microns in size. The new Vortisand unit was installed in early 2010, and after several months of operation proved to be a wise investment. Results: A quality submicron filtration system coupled with a comprehensive chemical treatment programme proved to be the key to reducing TSS levels.

Other positive outcomes: During a recent site visit in April 2014, Davis stated that he had never seen the chilled water this clean since the start-up of the facility in 2000. The TSS issues that previously plagued the entire system did not return. Earlier, their 15 heat exchangers had to be cleaned several times per year due to the increased biofilm caused by the suspended solids. “These heat exchangers have not had to be cleaned since the Vortisand was installed in 2010,” Davis said. Maintaining their design efficiency, Davis added, has improved the bottom line every year with a Return on Investment of less than 12 months.
