hen someone told me blockchain opens up a world of possibilities, I dismissed it as another example of the modernist tendency for hyperbole. That was till I better understood the Food Watch programme, being developed by Dubai Municipality, and widely expected to revolutionalise food safety management. Once out, the programme, perhaps the first of its kind in the world, will keep tabs on every single activity of every single food establishment or related business in the emirate. It will not expect people to follow a set of storing and handling practices across and down the cold chain in good faith, backed by random checks; rather, it will rigorously ensure that non-compliance is not an option, with every single indiscretion triggering an alert for immediate authority action. In a typical scenario, if a consignment of meat is rejected by a five-star hotel on grounds of temperature abuse – usually the result of an errant transport refrigeration operator subjecting it to cycles of freezing and thawing – the meat supplier possibly tries to palm it off to a lesser establishment that possibly has the means to only apply fewer checks. With blockchain, the ‘rejection’ is faithfully recorded and the information is available on a real-time basis on a tamper-proof public platform, which the owner of the lesser establishment can view. Checkmate! It boggles the mind to think where else blockchain can be applied in the HVACR realm. In a study we recently undertook on ducting systems installed in buildings, we learnt of how most of them were either improperly cleaned or not at all – for years at a stretch. With a real-time monitoring system and reporting structure, which would automatically notify all stakeholders, including building owners, occupants, service providers and regulatory authorities – like municipalities, utilities and healthcare agencies – in real-time, there is a possibility of proactive alerts and alarms for increased levels of humidity, contaminants, CO2 and other particulates harmful to human wellbeing and health. Likewise, leveraging on IoT and utilising a network of sensors providing feedback on thermal discomfort, say, or air velocity, could reveal much, including leakage in ducting systems, which globally is resulting in loss of energy worth billions of dollars. In the case of a District Cooling network, the thermal discomfort could be the result of a hydraulic imbalance, which is quite the bane of District Cooling projects. We are talking of a paradigm shift here, and of myriad possibilities. No modernist hyperbole, this. Empowered with information, we can possibly turn the corner into Decisive Action Street.

HAT IS THE THRUST ASHRAE IS GIVING TO DATA CENTRE COOLING, CONSIDERING THAT THEY REPORTEDLY CONSUME THREE PER CENT OF GLOBAL ENERGY SUPPLY? ASHRAE has just published a new technical standard on data centres. And the reason ASHRAE chose to publish a separate document for data centres is owing to the importance of data centres from an engineering stand point. Data centres are unique in terms of application of engineering. So that was the reason to have a separate document from 90.1, though they are still part of energy efficiency in commercial buildings.
A big issue is that people have always assumed that the only way to make buildings healthier is to increase the intake of outdoor air
WHAT CAN BE DONE TO ADDRESS THE NAGGING ISSUE OF TRYING TO INCREASE ENERGY EFFICIENCY WITHOUT COMPROMISING ON INDOOR ENVIRONMENTAL QUALITY? IEQ and energy efficiency have been a historical balancing act. We want to make sure buildings are healthy and energy efficient at the same time. A big issue is that people have always assumed that the only way to make buildings healthier is to increase the intake of outdoor air, and that by doing so, we would end up increasing the consumption of power to condition the air. We can, however, make our buildings healthy by doing other things than just

Tim Wentz , ASHRAE
COULD YOU SHARE INFORMATION ON ASHRAE’S RECENT DISTRICT COOLING INITIATIVES WITH EMPOWER? Clearly, District Cooling is one path that can offer significant energy savings for communities that are willing to explore the technology. At the Winter Meet (2017), Empower and ASHRAE signed up an agreement to upgrade the existing design guidebook. We also signed an agreement to do a District Cooling document specific for building owners, which we expect would take a year to produce. We have a design guide. But how do you get the owners on board, and how will they know the advantages District Cooling has to offer, and their responsibilities as building owners? It is a question of O&M. It’s like managing any other asset to get optimal energy efficiency.
increasing the intake of outdoor air. We are committing more to research on this subject. This issue is particularly at the forefront of healthcare. We are finding that we can, maybe, make hospitals healthier with less outdoor air, like controlling contamination within the building.
IS THERE CREDENCE TO THE THEORY THAT IF WE WERE ABLE TO GET MORE OUT OF RENEWABLE ENERGY TO CONDITION THE AIR, THEN THE ISSUE OF EMISSIONS WON’T HAVE TO CROP UP EVERY TIME SOMEONE SUGGESTS WE INCREASE THE INTAKE OF OUTDOOR AIR? If you are going to create a nearly zero energy building (nZEB), the first step is to lower the energy use of the building to a minimum level and, at the same time, keep the building healthy. Then you talk of renewable energy. Does IEQ have a role to play in the process? We would need to direct special research on ventilation rates and human occupancy. I think we have a lot to learn there yet.

IS THE INTERNATIONAL DISTRICT ENERGY ASSOCIATION (IDEA) INVOLVED IN THE PUBLISHING OF THE NEW GUIDE BOOK? Jeff H Littleton (Executive Vice President, ASHRAE): This is an ASHRAE and Empower project. We think very positively about IDEA, and they are a great group, but they are not directly involved in this project.

egulators, representatives from government bodies certification agencies, VRF manufacturers, consultants and contractors assembled on March 27 for the 5th Annual Middle East Variable Refrigerant Flow Conference at Al Yasat Ballroom, Roda Al Murooj Downtown, Dubai, with a slew of questions and an array of possible answers. Produced by CPI Industry, publishers of Climate Control Middle East, the event was held amidst growing positivity towards the technology as a strongly viable cooling approach. Among government agencies that participated were Trakhees and the Abu Dhabi Quality & Conformity Council (AD QCC). They were joined on stage by the European, Partnership for Energy and the Environment (EPEE) and Eurovent Certita Certification. Expectedly, the delegates were interested to learn more about how the agencies evaluated the performance of VRF systems. While Trakhees and AD QCC offered clarity, so did the two European agencies, whose representatives spoke on the SEER-based approach in evaluating performance. The conference also saw a crosssection of consultants speak of their experience with the VRF technology and, in a departure from past editions, elaborated on how VRF systems were proving capable of meeting energyefficiency goals in buildings and also reliability in cooling. That said, the consultants suggested areas for improvement. Here we bring for you, in pictures, the conference that was...

ADVERTORIAL
CLIVET ENHANCED HYDRONIC SYSTEM, THE NEW FRONTIER OF CENTRAL PLANTS uildings need a great amount of energy to be properly operated and maintain suitable comfort conditions to occupants. This behaviour becomes dramatic in regions with desert climate, such as Gulf Countries, where energy consumption for domestic and commercial buildings is up to 70% of the energy used and the most part of this is spent for air conditioning.
B
In order to grant optimal comfort conditions with a sustainable amount of energy, Clivet has developed the Enhanced Hydronic System. Based on high efficiency technology and reversible heat pump, it is a specialized and efficient answer to comfort requirements of shopping centers, offices, hotels, restaurants, entertainment, hospitals. CLIVET Enhanced Hydronic System is composed by 3 basic components: ZEPHIR3 stand-alone system for supply and exhaust air management with thermodynamic energy recovery, full fresh air operation, total humidity and automatic temperature control, electronic filtration able to keep 99% pure air
SPINchiller3 air cooled or water cooled multi scroll chiller for cooling with energy recovery for free domestic hot water ELFOspace cased and uncased fan coils with DC brushless motors for heating and cooling distribution with a saving of 60% compared to traditional fan coils The dynamic year-round analysis on a multi-level office building in the city of Dubai resulted in: Reduced energy consumption thanks to the autonomy (for most operating time) of ZEPHIR3 system for Primary Air treatment to produce heat and cooling capacity with thermodynamic recovery
Low power input for ventilation using the thermodynamic recovery: reduction up to 50% compared to the traditional solution High part-load efficiency of cooling technology using SPINchiller3 modular multi scroll Lower energy cost in year-round operation, with overall capital cost lower than traditional solution in most projects 20% reduction of plant overall dimensions

HINA PRODUCES 80% OF THE WORLD’S AIR CONDITIONING EQUIPMENT. IN AN INTERVIEW WITH CLIMATE CONTROL MIDDLE EAST MAGAZINE, THE PRESIDENT OF HISENSE SPOKE ABOUT HOW CHINESE MANUFACTURERS ARE JUST AS CONCERNED ABOUT PRODUCT QUALITY AND BRAND IMAGE AS THEIR GLOBAL COUNTERPARTS. WOULD YOU SAY THE STIGMA SURROUNDING THE ‘MADE IN CHINA’ LABEL IS RUNNING OUT OF STEAM?
Zakir Ahmed: ‘Made in China’ depends on what the customer wants. About 20 years ago, while in China, I went to buy a table fan, and he said, “What quality do you want? Do you want US quality or Middle East quality?” That was because the US quality had a certain class of motor and safety. China today makes the best quality phones (iPhones) and laptops (Dell); and Huawei is there. But the perception of China is bad, because traders go and buy the cheapest and dump it in the market, not because the country is incapable of manufacturing good products. The top three Chinese air conditioning companies make very good quality products, but the question is, ‘What is the perception about these three brands?’ If you take Gree, when we came to the UAE, five years ago, we faced initial resistance, but the same product was acceptable with a ‘Japanese brand’. So we took the issue head on by giving a full five-year warranty.
WHAT ARE THE GOVERNMENT-LED POLICIES, STANDARDS, CODES AND THE EVOLVING ETHOS THAT ARE UNDERPINNING CHINA’S INCREASED FOCUS ON QUALITY? Ahmed: Government regulation has driven energy efficiency up, and incentives are there for customers choosing to replace existing units with energy-efficient ones. At the same time, lifetime reliability of the product is important, and the top three companies in China are very good in the light-commercial segment. Gree in China dominates 50% of the market-share, because it has invested heavily, including in giving a seven-year warranty. Outside China, the quality is dependent on the buyer and not on the manufacturer. When Gree supplies products to the Gulf, if the standard demand is for performance at 52 degrees C, the

company tests at even 60 degrees C. So, this is the assurance of quality, because the real use of the equipment is in more hostile conditions. Kartik Iyer: China has evolved a lot over the years. It started out as a provider of cheaper products, but now is making products for the end-destination, and it gives the customer a wide choice. Today’s customer is more educated and has realised that it is the capability of the brand that matters more than where it is manufactured. The ‘Made in China’ label is no longer considered taboo. It might be used in the market in an attempt as a spec stopper, but the customer has broken down the barrier.
WE HAVE ALSO RECENTLY RECEIVED REPORTS THAT THE COST OF MANUFACTURING IS GOING UP IN CHINA. WHAT STRATEGIES WOULD CHINA LOOK TO BE ADOPTING TO KEEP ITSELF COMPETITIVE, COST-WISE?
Zakir Ahmed
Iyer: I think the cost of production in China is no longer a differentiator, because we are no longer talking of a US or a Chinese brand, but of equipment sourced from China. Most European HVAC companies have factories in China, so companies have to come up with an edge to position themselves. BUT THE COST OF MANPOWER IS MORE NOW, ISN’T IT?
Kartik Iyer
28
April 2017
Ahmed: Let’s take India and China as examples, because China has 30 million air conditioners in the domestic market, which is 10 times what it is in India. A huge demand has meant a large installed capacity. So even though the manpower cost is increasing, it does not affect the total cost of the product, owing to the capacity. If you compare with India, the cost of manpower in China is less per unit. A factory in Iran can make 200,000 units, whereas a factory in India can make one million units. In China, the number is at sixty million units, so ‘Made in China’ will continue to dominate. Also, Gree is on an automation drive. The company has automated the entire production line in one of its factories that makes compressors. And it is in the
process of converting a motors factory from manual to fully automated status. The company is going down this route, because it is not able to get enough manpower and not because it is going after cost-effectiveness. There is a shortage of skilled labour; people no longer want to do USD 200-400 jobs.
WHAT IS GREE DOING TO POSITION CHINESE BRANDS AS ADHERING TO GLOBAL CLIMATE CHANGE MITIGATING GOALS? Ahmed: Gree invests five per cent of its revenue in R&D every year. The Chinese government is supporting the cause of R-290 as a refrigerant. The company has already got acceptance from the US government and has shipped two million units to the United
Since the beginning of 2016, we have started following a consortium-based approach. We are putting a thrust on commercial or project-based approach
States for the purpose of testing. The units shipped have limited amount of refrigerant, which means they can be contained within the unit; that way, they address the fear over flammability. China has a bigger problem with global warming potential (GWP), owing to energy demand and population density. The country is looking for an environmentally friendly refrigerant, and views R-290 and R-32 as acceptable refrigerants in the global market as replacements for HFCs.
MEP CONTRACTORS OFFER SPECIALISED SKILLS, BUT OF LATE, WE SEEM TO BE HEARING

Zakir Ahmed & Kartik Iyer , NIA Limited
DISCORDANT VOICES OF HOW THE COMMUNITY IS HEADED TOWARDS DEMISE. THE PLIGHT OF THE MEP SUB-CONTRACTOR COMMUNITY IS REPORTEDLY DEPLORABLE. THEY REPORTEDLY SEEM TO BE CAUGHT IN A TIGHT SQUEEZE BETWEEN GENERAL CONTRACTORS, ON ONE SIDE, AND SUPPLIERS, ON THE OTHER. AS A SUPPLIER, WHAT CREDIT TERMS ARE YOU OFFERING MEP SUBCONTRACTORS? Iyer: As NIA Limited, we are trying to partner with stakeholders in the market. We follow the ‘Three C Approach”, which is the Client, Consultant and Contractor. And we believe in becoming part of the project and delivering value to the project. And through the consultant, we address the issue of optimising the solutions and in doing value engineering. We do pre-tendering in consultation with consultants. Since the beginning of 2016, we have started following a consortium-based approach. We are putting a thrust on commercial or projectbased approach, and we are planning our growth for the next few years; we see this as part of a bigger plan.
The contracting industry has gone through the worst crisis since 2011, and the challenge is to keep resources and bend backwards to make the project work
Ahmed: When you partner with them, based on the feasibility of the project, you have to go the full stretch and meet the demands of the project. Since we are not a market leader, we have to be flexible in commercial terms, price, deliveries and warranty conditions. We have full confidence in our product, so we are flexible on warranty conditions. The contracting industry has gone through the worst crisis since 2011, and the challenge is to keep resources and bend backwards to make the project work. In the process, there may be those that would use substandard materials, but it would be better for them to work with companies like us that give better products at better commercial terms. You spoke of the deplorable condition of contractors. Some of the comments coming from them are superficial. When we engage them, we find that some of the contractors are not doing enough to meet the needs of a project.
ARE YOU PARTICIPATING IN THE BUILDING-RETROFIT MOVEMENT IN DUBAI? HAVE YOU EVOLVED ANY STRATEGIES TO HELP BUILDING OWNERS? FOR INSTANCE, HAVE YOU CONSIDERED LEASING OF CERTAIN TYPES OF EQUIPMENT AS A POSSIBLE SOLUTION TO OVERCOME CRIPPLING CAPEX CHALLENGES THAT OWNERS FACE? FOR INSTANCE, WOULD YOU SUPPLY VRFS ON A LEASE-TO-HOLD BASIS?
▶ Hong Kong City, China
30
April 2017
Iyer: We are not yet considering this approach of leasing equipment. At least
for now, the commercial laws in the UAE probably do not give enough safety to invest in a venture like that. But we are very much part of the retrofit business when we go through key accounts. We get involved in retrofitting, wherein we study the application and do some value engineering at our end; that way, we add value in terms of capex or power consumption. Maybe moving further, we might see services as a profit division at NIA, where retrofit sales become successful, if they are a part of a service division. That way, when we take up AMCs, the best retrofit solutions can be advised. Ahmed: If they have to replace one-to-one system, they can go with VRF, so there is a great opportunity to improve energy performance. If the occupant moves out of his house for three nights, we can change the one-to-one system to VRF. And in the case of a villa, it is easier to make that change. But that would require a different team and focus. It would need a strong service division. Equipment sales and service business are two different aspects. In the second, we would have AMCs and retrofit sales.
LET’S BROADLY TALK ABOUT THE VRF MARKET IN THE GCC REGION. IN THE UAE, THE TECHNOLOGY HAS A SEVEN PER CENT PENETRATION RATE, WHEREAS IN THE GCC REGION, IT HAS A 4.5% PENETRATION RATE. IN YOUR VIEW, WHAT NEEDS TO BE DONE TO INCREASE THE ACCEPTANCE OF THE VRF TECHNOLOGY? Ahmed: The first restriction on VRF was cost. Earlier, the price of the equipment was 2-3 times more than what it is now.
If you allow a VRF system to be installed by someone who is not trained, be it in brazing, wiring or even selection, then it is a serious issue
The main driver for change is that earlier, we used to get an inverter compressor up to three TR capacity, and we had to use more units; today, we have a compressor of eight TR capacity. So you can use only one compressor, which means price savings, which in turn, means the acceptance and penetration will increase. Also, consultants had this perception that VRF is a complex system. Yes, they had cause to be concerned. If you allow a VRF system to be installed by someone who is not trained, be it in brazing, wiring or even
selection, then it is a serious issue. If not installed properly, it will lead to lower satisfaction. If the piping is not clean, or if the brazing is not done properly, you will have leakages. That is why we train people in our academy on what is needed to properly install a VRF system. We extend this facility to all stakeholders, including consultants and contractors to help in building awareness on not only how to install but also on how to make the design selection. Iyer: We are also engaged in an exercise where we are trying to engage some of our partners, who are installers of split systems, and who will now naturally progress on to installing VRF systems.

W
E ARE SEEING A SQUEEZE ON FINANCE, AND MANY GENERAL CONTRACTORS AND MEP CONTRACTORS SAY THEY ARE SEEKING FAVOURABLE TERMS AND CONDITIONS FROM SUPPLIERS. WHAT ARE YOU DOING TO SUPPORT THEM AND ENABLE THEM TO SUSTAIN THEIR BUSINESS? HOW IS JOHNSON CONTROLS HELPING? Ahmed Al Neama: While Johnson Controls is offering us a lot of support, however, Iraq is currently undergoing a lot of political transitions, and we are faced with a paradox of challenges. For instance, before financing of jobs, we have to be assured of funding for the project before it is commissioned. And the key decision-maker here is the government, which decides the budget. In the private sector, although there is cash- flow, yet the banking system is a challenge, because of the situation in the country.
Although the Iraqi market is still growing, there is tremendous demand for a lot of products and solutions
Abid Vazir: The relationship we share with Johnson Controls is beyond a distributor and manufacturer relationship. We have fostered a healthy partnership with Johnson Controls, and work together as a team, where we profile and exchange customer information, review and decide what would be the best possible solution or product for the customer. Johnson Controls is noted for being partner- and customer-centric, because they do not just impose solutions or offer just any product off the shelf; rather, they do analyse and understand the requirements of the customer and, then, offer the best efficient and cost-effective solution and products with long-term sustainability.
IN VIEW OF THE MERGERS OF JOHNSON CONTROLS WITH MAJOR BRANDS LIKE HITACHI AND TYCO, HOW DO YOU VIEW THIS AS A GROWTH OPPORTUNITY? Al Neama: These new mergers have definitely boosted our market presence. The complexities of dealing with different companies has now reduced to dealing with just one company, which offers everything in-house, thus facilitating hassle-free operations, allowing us to focus more on accelerating our market growth. Vazir: The mergers are very beneficial for our business, because this gives us an opportunity to introduce new products in
34

Pakistan, thus enhancing our sales graph. Pakistan is an emerging market with many untapped demands opening up. Hence, when Johnson Controls brings in brands like Hitachi and Tyco, it gives us an opportunity to increase our customer and product portfolio. These mergers also augment JCI’s and our presence in the local market.
SO HOW DO YOU VIEW JOHNSON CONTROLS AS A GLOBAL TECHNOLOGY PLAYER? WHAT IS YOUR VIEW ON THAT PROSPECT? Al Neama: Johnson Controls will grow well in the GCC region, and though the Iraqi market is in its infancy stages, I believe that Johnson Controls will become a key player in Iraq, owing to the local ground support, as well as from Dubai and the United States. Johnson Controls also offers us with the necessary support we need. Their research team is always ahead of the market, which is very beneficial for our business. The partnership we share with Johnson Controls scales up our own business in the GCC region and Iraq. Vazir: Since the Pakistani market is now opening up, the economy is growing at a steady pace. But there is a need for energyefficient product solutions, owing to the prevailing energy crisis in our country. Hence, when Johnson Controls introduces new products packed with energy efficiency,

WHAT ARE THE SPECIFIC CHALLENGES CONFRONTING YOU IN VIEW OF THE OIL PRICES AND UNCERTAIN MARKET SCENARIO? HOW ARE YOU RESPONDING TO THEM? Al Neama: Since most of our projects are in the private sector, we are not directly affected by the oil prices. As a matter of fact, I have been witnessing exponential growth in the private sector. Although the Iraqi market is still growing, there is tremendous demand for a lot of products and solutions, and many international companies are studying the feasibility of expanding operations to Iraq. The government has to commit themselves to ensure political security and stability, in order to witness positive long-term results.

itchen exhaust ventilation and pollution control at food outlets and restaurants are becoming more and more challenging and present themselves as a two-fold problem: Firstly, to provide safe and comfortable indoor conditions to the occupants and remove contamination during the cooking process, and secondly, to solve outdoor pollution, since intensity of pollutants vary drastically due to the type and frequency of cooking and other complex factors, such as wind speed, direction and discharge constraints, that are beyond one’s control. The focus, therefore, needs to be to remove air-borne contaminants aimed at odour reduction rather than elimination.
Pointing out that airborne particulate and odourous gaseous contamination in commercial kitchens, such as hotels, food courts and restaurants, pose health and safety hazards, Danish Sameen stresses the need for ecological solutions for kitchen exhaust treatment.

Another danger is when untreated primary kitchen exhaust air migrates from an outdoor air intake back to the building, causing “shortcircuiting� of air
COMBATING EXHAUST CONTAMINATION In the given scenario, “primary exhaust” refers to the air exhausted directly from the kitchen area via the kitchen hood. This exhaust contains all sort of contaminants that have emanated

through the cooking operation. The primary exhaust applications, therefore, need correctly designed “kitchen ecology” units to eliminate grease, moisture, smoke and odours, to ensure the safety and performance of the system. Hence, hotels and large restaurants
need to strive to mitigate exhaust contamination by efficient means to ensure their exhaust emissions and odours do not reach the neighbours or the vicinity, which could be sensitive locations, such as offices, banks, prayer areas and shopping arcades.

Another danger is when untreated primary kitchen exhaust air migrates from an outdoor air intake back to the building, causing “short-circuiting” of air. In case the kitchen exhaust locations are too close to outdoor air intakes, then there is a danger of odours travelling back to occupied buildings or to the neighbouring facilities. This is because the odours from the primary exhaust do not “fall out” of the airstream and remain untreated. Hence, odour control due to air shortcircuiting or infiltrating to neighbouring facilities need to be addressed by installing gas phase filtration in the affected fresh air intake or air-handling units (AHUs). This scenario is an example of “secondary exhaust” air treatment.
Commercial kitchens typically include hoods with baffles to remove the initial amount of grease aerosols and particulates from the cooking appliances. The fact remains that filtration of these baffles is often ineffective and, therefore, contaminants can easily travel down to the discharge point.
KEEPING AN EYE ON KITCHEN HOODS It is extremely important to select the right type and size of hoods for specific cooking needs, as this is the main source of control of contaminants. Most kitchen hoods are provided with make-up air in the range of 85% to compensate for the amount of exhaust, and allows the air in the kitchen areas to be balanced. The volume of air extraction at the hood is a key parameter for any successful installation and, therefore, thermal convection method is suggested as the most

prevalent and effective one. However, other provisional methods are also used to calculate the hood exhaust flow rates, which are derived from Face Velocity Method, that is, by selecting velocity across the face-area of the canopy. This
method is adopted to calculate the rate of exhaust based on light loading, such as steaming ovens and boiling pans; medium loading, such as deep fat fryers and griddles and heavy loading devices like chargrill and broiler units.

The particulate or solid particles comprise food deposits and hydrocarbons or smoke. While smoke can be reduced by removing the particulates, it is the gaseous contaminants or vapour containing odour that need to be treated. These odour molecules pose a challenge, as they are too small to be removed by filtration alone. The solution, however, can be found by a combination of techniques that vary, based on the problem.
CAPTURING THE CONTAMINANTS The amount of heat and contaminants generated varies from type and load of each kitchen. These contaminants are generated by the combustion of meat and vegetables, and convict heat coming in the form of smoke, grease aerosols, cooking odours and water vapour.

ERSPECTIVE
FILTERING OUT POLLUTANTS A basic filtration unit, termed the Kitchen Ecology Unit or Pollution Control Unit, may be used, containing three stages of progressively more efficient filters: Washable permanent pre-filters precede a 95% efficient bag filter, followed by a 99% absolute filter. This system will help reduce the visible particulates that is, smoke, to a maximum level of 0.3 microns, but will not deal with any odours or the gaseous phase because of the sub-micron size of molecules. As an alternative to the second and third stages of filtration, an Electrostatic Precipitator (ESP) can be deployed, which is a permanent-type, low-pressure resistant device that is electrically operated by ionised collector cells. However, it needs to be stated that higher temperatures and humidity may result in a drop in ESP efficiency.
Washable Filters
At the final phase, ecology units treat odours (gases), which are typically classified as volatile organic compounds (VOCs), by using special gas phase filtration media, such as activated carbon. They utilise pore structure and surface area to adsorb the odours. It needs to be noted that as surface area and pore structure are critical, the filtration unit must remove all grease and mists before the exhaust air contacts the gas phase

media. Otherwise, the media will be rendered useless and can become a fire hazard. These gas phase media units can be mounted in the form of refillable canisters, trays or cassettes. The chemical media
differs in type and quantity of activated carbon, and its impregnation is meant to target the particular gas adsorption. In some instances, blended media or potassium permanganate is also used for a wide variety of odour abatement.
Figure: Gas Phase Cassettes and canisters with activated carbon or potassium permanganate media
95% Bag filters
Another technique used for odour neutralisation is to deploy a liquid spray system that injects a neutralising liquid to the upstream of the extract fan. However, one should be careful while sizing and selecting this system. This process is not an odour-masking technique, but is used to defuse the odour molecules by a reactive chemical process for the permanent destruction of odours in an environmentally friendly manner.
FAN – THE DRIVING FORCE The driving force of the kitchen ecology unit is the fan, as it pulls out the right volume of contaminated air by overcoming the system resistance that is, the overall system static pressure. A wide variety of fans are available in the market to suit the requirements. However, predominantly, centrifugal fans in DWDI (Double Width Double Inlet) or SWSI (Single Width Single Inlet) configuration are used. DWDI fans are versatile, and are housed inside the casing, thus forming an integral part of the Ecology Unit, whereas SWSI fans are ducted out, and provide extra safety towards fire hazard, since the drive remains out of the air stream. Also, certified and listed fans with extra features, such as temperature rating, inspection hatch, shaft – bearing heat slinger and casing drain plug – can be opted, depending on the criticality of the kitchen and building norms.
FIRE SAFETY – WALKING THE EXTRA MILE Fires in commercial kitchens are always catastrophic, because such fires have a significant amount of combustible elements, such as cooking fuel, grease, wood, décor furniture, etc. Such accidental fires not only mean serious threat to life and collateral
losses but also damage the reputation of the establishment, probably leading to business closure and rebuilding it. Therefore, keeping to proper maintenance schedules for exhausts ducts and filtration systems promotes their long-term performance and reliability. Other fire safety and prevention devices, such as sprinkler systems, smoke sensors or fire probe, fire dampers and control panels with alarms could also be included in the array of safety measures used. In addition, the overall system should be in compliance with fire, smoke and safety regulations, in accordance with civil defence and other applicable local norms and statuaries. On its part, the directive of the local municipality within the region, needs to ensure that all kitchen exhaust units are properly and effectively treated before deploying the systems. More and more stringent local norms are coming into effect in the Middle East. Also, the developers, owners and tenants are pressing into service suitable kitchen treatment units with the help of design engineers and consulting offices. Equally, renowned companies are developing their products to fill the gap in demand, and customising them as per customers’ needs.

ost chilled water plants today utilise electric-driven, constant speed centrifugal chillers with a primary/secondary pumping system. This type of system was developed to meet the chiller OEM requirements for the operation of chillers, while also meeting the chilled water pumping requirement to the cooling load. The primary/secondary pumping system, in general, consists of two hydraulically independent circuits connected by a de-coupler. The two circuits include a constant volume loop (primary), which circulates the Chilled water through the chillers and a variable volume distribution loop (secondary), which circulates chilled water through the distribution system. The hydraulic independence of each loop prevents variable flow in the secondary loop from affecting the constant flow in the primary loop. Each loop includes a set of pumps sized to deliver the same flow rate against the individual total dynamic head of each loop. The chilled water circulation (primary) pumps are constant volume and the chilled water distribution (secondary) pumps are variable volume, operating from a variable speed drive. This allows the chillers to receive the constant design chilled water flow rate, while the distribution system flow rate can vary to match the actual load. The de-coupler is typically located at the suction header of the secondary pumps and at the suction header of the primary pumps. When the secondary flow requirement is higher, the water will flow from the return water directly through the de-coupler and mix with the supply chilled water. When the primary flow exceeds the secondary flow,
the supply chilled water will flow through the de-coupler and directly back to the chillers. The optimum way to operate this system is in a neutral situation (no flow through de-coupler) or slightly positive (slight flow from supply chilled water back to chillers). Although this is a very good pumping system, it is not the best system when low Delta-T syndrome is an issue. The following is a list of disadvantages of a primary/secondary system: 1. It does not resolve low Delta-T Syndrome: The primary/secondary system does not allow an increase in flow through the evaporator above design and, therefore, does not adjust to chilled water return temperatures that are lower than the design. Today’s chillers are or can be designed for variable flow service. In addition, this pumping system can lead to huge problems during off-peak conditions. As the cooling load decreases, the secondary pump VFDs will ramp down to a lower speed, thus allowing these pumps
Today’s chillers are or can be designed for variable flow service
to produce less flow. The constant volume circulation pumps will, then overpump the primary loop, causing supply water to flow through the de-coupler and mix with return water. This mixing lowers the return water temperature and deteriorates the system Delta-T. 2. Capital Investment: The greater the quantity of pumps and the longer the piping run associated with this pumping system, the higher is the capital investment when compared to a VPF (variable primary flow) system. 3. Higher operating and energy costs: The primary/secondary system uses both constant speed and variable speed pumps to circulate chilled water through the plant as well as the distribution network. Because the primary loop will always have a constant flow, energy is wasted within this loop at off-peak loads. In addition, this pumping system does not allow for variable flow through the chillers, and is subject to

VPF PUMPING SYSTEM – A STUDY
Because the primary loop will always have a constant flow, energy is wasted within this loop at off-peak loads

April 2017
The use of VPF pumping (variable flow through chiller evaporators) in chilled water systems is increasing due to its potential to reduce energy consumption and initial cost relative to primary/ secondary pumping arrangements. Current thinking on the use of variable primary flow chilled water systems, and literature review of designers, owners and chiller manufacturers all seem to endorse this pumping arrangement. To quantify the energy use and economic benefits of variable primary flow system, an extensive parametric simulation study was conducted by Pennsylvania State University that compared VPF system energy use with that of other common system types. System types included in the study were constant flow/primary-only,
constant primary flow/variable secondary flow and primary/secondary with a check valve installed in the de-coupler. Parameters varied, included load type, number of chillers in the central plant, temperature difference versus part-load characteristics and climate.
PARAMETRIC STUDY FINDINGS Variable flow, primary-only systems reduced total annual plant energy by 3-8 per cent, first cost by 4-8 per cent and lifecycle cost by 3-5 per cent, relative to conventional constant primary flow/variable secondary flow systems. Several parameters significantly influenced energy savings and economic benefits of the variable primary flow system relative to other system alternatives. These included the number of chillers, climate and chilled water temperature differential. The following factors tended to maximise variable primary flow energy savings relative to other system alternatives: 8]^aaZY lViZg eaVcih l^i] [ZlZg X]^aaZgh Adc\Zg! ]diiZg Xdda^c\ hZVhdc AZhh i]Vc YZh^\c X]^aaZY lViZg temperature differential (low Delta-T Syndrome)
technology chillers installed and VPF pumping networks, the chilled water plant can run very efficiently even under low Delta-T conditions. On the building side, proper selection of equipment as well as proper installation and ongoing professional O&M will also reduce low Delta-T. On existing plants, even with primary/secondary pumping arrangements, I would suggest VFD (Variable Frequency Drive) retrofits on your existing chillers. It will make your plants more
efficient and, will, without question, resolve the low Delta-T inefficiencies. It will not eliminate low Delta-T, but will at least allow you to stop suffering the increased cost of low Delta-T.

The magnitude of savings was much larger for greater cooling loads, but when savings were standardised on a per design tonnebasis, the differences were relatively small. Chilled water pumps and chiller auxiliaries accounted for essentially all savings. Differences in chiller energy use were not significant from system type to system type. Variable flow, primaryonly systems chilled water pump energy use was 25-50% lower than that of primary/secondary chilled water systems. In systems with two or more chillers configured in parallel, chiller auxiliary energy savings were 13% or more relative to primary/secondary systems. The addition of a bypass check valve to the constant flow primary/variable flow secondary system resulted in total plant energy savings of up to four per cent and a lifecycle cost savings of up to two per cent. Savings occurred only when chilled water ΔTs were less than the design value. Chilled water pump savings was five per cent or less, and chiller auxiliary savings was 13% or less.

However, so many of the design decisions made every day have a climate implication; each one can help promote a low-carbon future that doesn’t rely on fossil fuels.

The important thing is to raise these questions early, such as when choosing a building’s site or selecting a material for a new product
UNDERSTANDING THE PROBLEM Climate change is real and progressing: 2016 was the hottest year on record, for the third consecutive year. The effects of climate change are evident in rising sea levels, more frequent and intense storms, droughts and floods. Changes in weather patterns create resource scarcity, displaced communities, increased risk of disease and political and economic turmoil – all profoundly impacting people’s lives. Global warming is more than an environmental issue; it’s a human issue. And it is also a business issue. Energy is one of the largest contributors to climate change, accounting for 84% of greenhouse-gas emissions in the United States. And as temperatures rise,
so will energy costs, the US EPA (United States Environmental Protection Agency) predicts. Fortunately, the 2015 Paris Agreement is an encouraging step towards ensuring those rising energy needs don’t mean catastrophe for the planet. The Agreement forged a consensus among 197 nations (despite recent claims that US President Donald Trump is preparing to withdraw) to keep average worldwide temperatures from rising more than two degrees C, thus averting climate calamity. But to achieve that, there’s work to be done.
DESIGN AND CLIMATE CHANGE The most significant way designers and engineers can address the climate-change challenge is by designing for higher productivity. Increased productivity requires maximising value (output) while minimising costs (inputs, such as energy and material resources). In terms of architecture and construction, that could mean designing buildings that use less
Designers and engineers who use the process of whole-systems thinking consider the interrelationships between complex systems, instead of focusing on an individual part of the system
energy. On the manufacturing side, it could be designing products that last longer and use less virgin material. One thing is certain: Energy and resource productivity is paramount in all forms of design. Designers and engineers, who are designing for higher productivity – and, thus, addressing climate change – typically employ the five approaches discussed here:
1. ASK ENERGY-PRODUCTIVITY QUESTIONS UPFRONT From the start, asking questions, such as “What is the energy implication of this design decision?” or “How will this choice increase energy and resource productivity?” ensures that designers and engineers keep costs down while adding value. The important thing is to raise these questions early, such as when choosing a building’s site or selecting a material for a new product, and often, thereby setting the precedent for continued sustainable design choices throughout the life of

the project. Those seemingly small decisions add up to big impacts. Shanghai Tower, China’s tallest building, saved 25% of its material costs, because the architects focused on how to make the structure lightweight while maintaining its strength. And they did that by analysing how wind would strike the building and, then, shaping it into a twist so that it would cut through the wind. Those decisions were planned from the beginning of the project, not tacked on as a “green” afterthought.
2. MODEL, SIMULATE AND REPEAT It is now easier than ever to evaluate early design decisions by using simulation technology to quickly model and test alternatives. Electronics company Opto 22 discovered this firsthand. The company analysed the electronic cooling for its Groov hardware interface (used to control the Bellagio Hotel fountains, among other things) with the goal to give the device a smaller form factor. The redesigned interface eliminated all moving parts, including two

fans, resulting in greater energy efficiency, reduced raw-material requirements and lowered costs for assembly and labour – a full 70% savings in labour costs. If designers and engineers, like Opto22, use the simulation tools available today, they can run the early analyses that yield similar energy, material, or time savings, while also saving money. But project stakeholders must be aware of the gains so that they start to expect and even demand sustainable practices throughout the design and engineering process.
3. TAKE THE LONG-TERM VIEW It is important that designers and engineers make long-term decisions that consider the product or project lifecycle. Take industrialfan manufacturer, Howden France, for example. The company analysed its fan wheels, accounting for fatigue and adjusting their thickness and weight. Optimising the
wheels’ weight enabled Howden to reduce the fan’s inertia, leading to better lifetime performance and reducing the power required for the motor. And that led to lower operating costs – a big win for customers. Designing for repair is also key; after all, the most sustainable product is often the one that lasts the longest. HP knew this when it released the Elite x2 1012 GI tablet. The company offers online repair documentation and readily available replacement parts so that users can repair their units themselves.
4. CONSIDER THE WHOLE SYSTEM Designers and engineers who use the process of whole-systems thinking consider the inter-relationships between complex systems, instead of focusing on an individual part of the system. This is important because most of the challenges that we face in society, like climate change, represent a set of interconnected issues that cannot be solved in isolation. By taking a big-picture view and considering the whole system, the most important opportunities often arise, and can be incorporated, early in the process. The team behind the Urbee hybrid electric car applied wholesystems thinking to the goal of producing an affordable, fast and safe method of personal transportation that runs on a small amount of energy. By taking into account all the interdependent factors and uncovering issues they could address upfront, they were able to deliver a fuelefficient hybrid that gets 150 miles to the gallon (241.4016 kilometres to the litre) and weighs just 1,200 pounds (544.3108 kilogrammes).
5. COMMUNICATE Designing for higher productivity will result in cost savings for customers and more value delivered. But those victories must be communicated to customers. It is up to designers and engineers to educate their clients, suppliers, subcontractors and colleagues about the choices that can make a real difference to the bottom line – and to climate change. Global architecture and engineering firm, HOK has taken significant steps in this area by signing on to the AIA 2030 Commitment. This national framework tracks progress towards meeting the Architecture 2030 Challenge, which charges the worldwide design-build community with achieving carbon neutrality on all new buildings, developments and major renovations by 2030. “More of our designers are engaged in energy discussions with clients, engineers, contractors and consultants,” says Anica AVcYgZcZVj! =D@¼h 9^gZXidg d[ HjhiV^cVWaZ Consulting. “Having discussions about energy efficiency earlier and more frequently in the design process has enabled us to identify significant first-cost and operational savings for our clients.” Simply put, sustainable design is good design. And responding to climate change is much more pressing today than ever before. If more designers and engineers commit to asking efficiency questions early, using simulation and analysis tools, and taking a long-term and whole-system view, the climate-change needle will move. And the best part is, they will be reducing emissions while increasing value for their customers.

HE BACKGROUND
Abdali is Amman’s new downtown district that provides the Jordanian capital with the central business, social and residential destination it needs as a regional business and tourism hub. An ample investment for the creation of modern and luxury buildings, towers, residences, business centres and commercial areas has been developed with a total value of more than USD 5 billion. A lot of green areas, parks and a central boulevard have also been included in the project for people to get around on foot and enjoy the scenery. Araner, an engineering group specialising in refrigeration, cooling and heating, was tasked with finding thermal comfort solutions.
CASE-IN POINT The challenge – what did Abdali need? The weather in Amman is quite extreme – incredibly high temperatures during summer and freezing night-time temperatures in winter make it difficult to live indoors without heating and air conditioning.

was calculated to be 52,000 TR. Efficiency is a crucial parameter for these kinds of plants, as the amounts of energy consumed throughout the year is very high. Any improvement in efficiency would result in huge savings in any developer’s running costs. Reliability was also a must, as so many residences, hotels, people and businesses depend on it. Those requirements are typical of any District Cooling plant worldwide. The original solution considered in the early design stages was a District Cooling plant with centrifugal chillers and cooling towers. Cooling towers constitute the traditional solution implemented in District Cooling plants in order to increase the chiller’s efficiency. However, the disadvantage of cooling towers is that they have a very high water consumption rate. The original design concept would have implemented a grey water supply from the municipality that would be treated in a water treatment plant inside the District Cooling Plant. The problems with this solution were threefold: I]Z XVe^iVa Xdhi d[ i]Z lViZg igZVibZci plant I]Z deZgVi^dc VcY bV^ciZcVcXZ Xdhi d[ the plant, mainly due to the extensive chemical treatment required and the cost of the waste management LViZg igZVibZci eaVcih jhjVaan Zb^i undesirable odours, which are not compatible with the level of luxury desired for the new developments.

April 2017
In order to avoid the problems of water consumption and a water treatment plant, Araner proposed a design based on aircooled chillers with zero water consumption. It is commonly understood that aircooled chillers are less efficient than chillers with cooling towers, and this is true for most design conditions. However, out of the design conditions, the benefit of a cooling tower when compared with an aircooled chiller is not that high, and may not really compensate for the additional water consumption. This is the case in Amman, where the temperature at night decreases drastically, and it is close to the wet bulb temperature.

ASE-IN POINT
Araner’s air-cooled chillers were able to achieve almost the same yearly average COP than a system based on cooling towers but with zero water consumption. Positive results were achieved by deploying three products: 1. Direct condensation chillers, which are more efficient than the traditional indirect condensation chillers (which is the case with centrifugal chillers with cooling towers) 2. The implementation of long-term thermal energy storage tank, which allows the chillers to work mainly at night with low ambient temperatures for more than 70% of the hours per year 3. R-717 refrigerant, which is more efficient than typical Freon refrigerants In addition, it is much more environmentally friendly.
PROJECT EXECUTION: The relationship between Araner and the Abdali District Heating and Cooling started in 2009 with the installation of a temporary plant with a capacity of 2,500 TR supplied by two chillers of 1,125 TR each, and one boiler of 5,000 KW. They could easily satisfy the demand that the developers had at the early stages of the District. Five years later, at the end of 2014, when most of the buildings had been occupied and the demands could no longer be satisfied with temporary chillers, the construction of the final plant started. In order to be able to provide cooling and heating at the right time, the project was defined by two key milestones:
The energy consumption all around the year is very similar to a system with cooling towers, but the water needs are eliminated
MILESTONES
The main challenge of the project execution was to achieve these two deadlines within a tight framework, bearing in mind that within 274 calendar days (nine months), only the skeleton of the building and half of the tank, where the electrical rooms should be placed, would be erected. In order to reach these targets, close coordination between civil, mechanical, electrical and control departments was undertaken to install all of the equipment with the required quality and within a very tight schedule. Araner’s personnel from different departments were mobilised to the site to supervise the installation and commissioning of the main equipment. For Milestone 2, the chillers installed in the temporary plant were dismantled and delivered to Araner’s workshop in Spain, in order to carry out maintenance and install all the improvements that had been developed by Araner’s engineering team during the past years. Changes to the discharge line, modifications in the oil separator supports, rearrangement of the interior piping or oil separator filters were just some of the modifications that were applied in the compressor units in order to improve their performance. Thanks to the quality of equipment installed in the compressor units and good maintenance performed by the company’s O&M team, the components were still in perfect condition after six years of working.

‘Projects have gone down, while competition has gone up’ Although research suggests that the HVACR accessories sector is poised for growth in the coming months, industry insiders concur that the sector is faced with a number of challenges.

npredictable oil price, inconsistent cash flow and pricing are some of the problems that stare at the HVACR accessories industry today. “One of the critical problems that this particular sector is facing is smooth cash flow,” admits Pramodh Idicheria, Executive Director at AZb^cVg 6^g 8dcY^i^dc^c\# ¹I]Z number of projects has gone down, while the competition has gone up, and we have the same number of competitors who are trying for less number of jobs. Although for 25 years, we never compromised on quality, and contractors are happy with the brands we offer, yet they do compare our products with others and ask us to match the price.”
PRICING, CASH FLOW AND OPPORTUNITIES Voicing similar concerns on cash flow and pricing challenge, other industry insiders agree that it is, indeed, a thorn in the flesh. Umesh Unni, Regional Commercial Manager (Insulation) of Hira Industries, says, “Banks are very strict on loans, and contractors are not able to function as how they used to, thus bringing a slowdown in cash flow.” On the pricing challenge, he says, “Price issues are skewing because contractors always try to get the lower price, and they put pressure on us to bring it down.” Raphael Khlat, CEO of Faisal Jassim Trading Company, elaborates, “Prices are being controlled by contractors, and it is a tight pricing market and when the client insists on a particular quality, the onus is on the contractors to deliver, who in turn, put pressure on us.” Kishore Deotarase, General Manager at Unigulf, adds: “The major challenge in the current market scenario is pointing towards the cash flow across the supply chain, and this is leading to delays in the projects’ execution.” Agreeing on the issues faced by the suppliers, Sibin James Chacko, Executive Director of EMCC, says, “There is a significant cash flow problem when you look at receiving advances or, for that matter, building owners wanting to cut down

maintenance cost because of low occupancy in buildings, thus vetting out contracting jobs.” On the price control issue, Chacko says: “Contractors do control the market, because we win a project based on certain criteria we price it at, thus getting squeezed by the client from that aspect, because we normally go for an auction, where we bid. Hence, we have the highs and lows of our criteria placed in every variable cost centres and fixed cost centres. We know our margins. And sometimes we will try to lower our margins to see where we can fit the specifications in, and that is where we get our foot in the door, because we can supply and install these specifications, which does have the upper hand than the manufacturers and suppliers.”
The Dubai Supreme Council of Energy has drafted a strategy to reduce the demand in power consumption by 30% by 2030. Industry experts confirm that their products align with this vision. For example, Deotarase says: “We are able to substantially contribute to the mission of
Kishore Deotarase
Suggesting a strategy to resolve the issue, Chacko suggests that manufacturers and suppliers must not be tied down to a certain kind of protocol but must be flexible and move in synchronisation with contractors when it comes to deliverables. From a contractor’s perspective, challenges may differ, believes Chaco. He says: “Currently, the main issue we face right now are product specs, because from the point of quotation to the point where it hits the ground, product specs are always changing. Hence narrowing it down to specs, I think there is a blank which needs to be fulfilled. The usual problem is that product specs are not mentioned in the required detail, which causes a hindrance to us when we quote for a project, and this is important because, after sharing a quotation, we have

clients who will initially scale up or scale down the requirement, and then they question the price, because it is different from the original quotation. On the flip side, we also have consultants who will point to us a clause mentioned on page 50 of an 800-spec sheet, and this is what throws us off in our pricing, and we try to battle it out as a variation versus part of the scope.”
Sibin James Chacko
the Dubai Supreme Council of Energy to save power consumption with our easy preinsulated panels that have minimum air leakage and excellent thermal insulation value. Therefore, electrical consumption results in up to 25% savings of energy because of good thermal insulation properties.”
REGIONAL PROSPECTS The question whether or not the two major upcoming regional events – EXPO 2020 Dubai and FIFA 2022 to be held in Qatar – will have a major impact on the sector has been under debate for long. About this, Idicheria says, “Though most of the infrastructure in Dubai is ready for the EXPO 2020, yet it will not take the market to a different level.” As for FIFA 2022, Idicheria adds that the country will offer more opportunities from 2018 onwards owing to the massive demand for construction and infrastructure. What will happen post these two events is another question. Expressing concerns, Chacko says: “We are all going by estimation of the number of people expected to come in for these events, but we must have a game plan, post the Expo 2020 or Qatar 2022. My fear is that if the enthusiasm is not sustained post each event, investors might lose interest in investing in the region.” Elaborating further, he says, “While 2020 is a good thumb rule to generate investor response, similar programmes must be conceptualised to boost investor interest.” On the challenges in the region, Chaco says: “While we can see that Dubai is well-positioned because of its progressive thought process, calculated strategies and
systematic implementation, thus attracting more investors, in Abu Dhabi, investors are challenged with new rules and sudden changes from regulatory bodies, hence hindering progress.”

he Gulf countries are recently experiencing a contraction in business as a result of erratic oil prices. In response to this, oil exporting countries, such as Qatar have developed and implemented their own strategy in order to stay afloat. AVhi 9ZXZbWZg! FViVg¼h B^c^hign d[ ;^cVcXZ announced that the country will allocate QR 93.2 billion for its projects, divided across infrastructure and transportation programmes, FIFA World Cup-related projects, health and education and miscellaneous projects1. It is evident that public spending for the year is set to continue, as the country makes an effort to ensure that all major projects are finished on time. However, the market is proceeding with caution in its move to complete long-term goals.
We look forward to see District Cooling as the cooling technology of choice in the State of Qatar, building on the sustainable development pillar of the Qatar National Vision 2030
62
April 2017
“Qatar’s District Cooling market is surging in line with its National Vision 2030, wherein it aims to achieve an advanced, sustainable and diversified economy,” says Mohannad Khader, Director, Business Development Department at Qatar Cool. “The government is strongly supporting the growth of the District Cooling market, and an important indication of this is the establishment of the District Cooling Services Department within KAHRAMAA, which came into existence with the resolution from the Council of Ministers. This only proves the government’s recognition of the many advantages of the industry for its efficiency, and also due to its conservation of electricity.” Khader adds: “Although it may be difficult to directly compare the District Cooling efforts of each of the GCC countries, as it depends on the construction of projects taking place in each country, we should expect to continue to see a surge in the Qatar’s District Cooling market, as the use of the system is being considered, and in many cases, already selected as the method of air conditioning for several upcoming major projects, in the country, including the cooling of the new stadiums hosting FIFA World Cup 2022.” Salah Nezar, formerly involved in the building construction industry in Qatar, admits, “The market in Qatar is very slow, and the cash-flow is an issue. So, the focus now in Qatar is going towards the rails and infrastructure: Roads, bridges, and also stadiums. Compared to other countries, it is moving forward; they have a deadline. They move in a very optimised way.” Nezar explains that the District Cooling sector is progressing in light of the infrastructure projects, as one of the main stations, Msheireb, has opted for the District Cooling option, emphasising the need to ensure all aspects are optimised, including piping and reticulation. He reveals that the work on stadiums is also progressing steadily, with Khalifa International Stadium to be inaugurated with full-fledged air conditioning systems in the next 2-3 months, as also the jeXdb^c\ AjhV^a >Xdc^X HiVY^jb! l]^X] ^h hZi to host the final matches. Robert Miller, Technical Specialist, District Cooling, at Marafeq Qatar, affirms this: “These stadiums have to have large loads, and they have central cooling plants. In BVgV[Zf! lZ VgZ XdcXZcigVi^c\ dc AjhV^a City, which has one stadium for the FIFA World Cup. From that perspective, things are moving ahead in an orderly fashion.” Although Miller admits that oil prices are

Qatar Cool’s Integrated District Cooling Plant (IDCP) was inaugurated in November 2010, and is the largest cooling plant in the world.” Khader further adds: “One of our most recent and inspiring projects is our agreement with The Qatar Railway Company for the provision of District 8dda^c\ id hZkZc d[ 9d]V¼h bZigd GZY A^cZ

which are in the process of being reviewed by companies with interests in Qatar. The new rules will have a definitive impact across the sector. Miller observes that this additional factor has been worrisome, and will have people asking the questions: “What are these regulations going to look like? And how will they affect our plans?” All these things spell uncertainties, Miller believes. He voices this, when he says, “Regulations are coming into focus and the government agencies are not in step with each other, which is an impediment to us.”

An example of a regulatory challenge that we may face is related to the use of Treated Sewage Effluent (TSE) instead of potable water in our plants in the West Bay district.

The call for greater integration among regulation bodies is palpable, with Nezar offering his candid observations: “Yes, there is synergy. Optimal? I don’t think so, but they are trying.” Miller adds that there is a strong recognition towards the need for consistency, with a slew of public announcements championing efforts to work together, but there is still room for improvement, as it continues to affect all aspects of the industry. In Kumar’s opinion, there have been a few regulations for air conditioning units and ventilation fans in the past three months, and there has been a slowdown in terms of delivery in the market. “We have the Qatar Construction Standards; they have some of the regulations on voltage and reports and certification for ventilation fans and air conditioning impact,” Kumar says. “So it had an impact not on the order booking but on the delivery.”
INNOVATION – A NECESSITY Although the new regulations may pose a challenge, the move can play a vital role in driving innovation in Qatar to implement increasingly more efficient solutions and urge manufacturers to do their part with regards to meeting the long-term sustainability goals of the country as whole. 8dbeVc^Zh! hjX] Vh AZb^cVg!

It is a good move so the market becomes more organised.” Khader elaborates on the point:

COUNTRY REPORT
Qatar
“Considering the rate of development we are witnessing in the State of Qatar, it is imperative that new developments and projects adopt a more sustainable cooling technology that does not consume a lot of electricity, especially since 70% of the generated electricity in the region is currently used for air conditioning purposes. With the advancement of District Cooling in Qatar, new project owners and developers now have a choice to opt for a more sustainable and environmentally friendly cooling solution for their new projects. The increased popularity of District Cooling is continuously improving the prospects of the industry, and we have witnessed a sizable growth in new connections during the past few years. Accordingly, we have started working on our fourth District Cooling plant in Doha to satisfy the increasing demand.” Khader believes that Qatar’s ambitious development programmes, particularly in large residential and commercial developments in the West Bay area, will drive demand for District Cooling even further, which will most likely push for more government regulations and endorsement. “That said, it is very important to think wisely about erecting new District Cooling plants,” he stresses, and explains: “As we foresee some changes in market dynamics, we still believe that decisions regarding new plants will depend on different variables, such as geographical location, economic feasibility and population density. Nevertheless, we remain optimistic about the future of the

industry, and we look forward to see District Cooling as the cooling technology of choice in the State of Qatar, building on the sustainable development pillar of the Qatar National Vision 2030.”
ROOM FOR GROWTH AND DIVERSITY Despite a few bottlenecks, there is a strong drive for the country to proceed, slowly but steadily, championing the value of pragmatism and showcasing a preference for solid feasible projects over flashy undertakings. In this context, Miller says: “We have a much broader outlook on District Cooling i]Vc _jhi AjhV^a 8^in! Wji ndj ]VkZ id `ZZe ^c b^cY AjhV^a 8^in l^aa ]VkZ [djg eaVcih with 350,000 tonnes. So this is a massive undertaking, and it will stretch out to several decades. But we recognise other opportunities in Qatar and other GCC countries, we are looking at it from a business perspective.” It is evident that Qatar’s cooling sector is striving towards innovation as a solution to optimise all resources in the most effective manner possible, with established companies looking for creative ways to survive impacts of the market and gain a competitive edge. “Innovation has been in the DNA of our company since its inception, and we have brought that same focus and dedication to Qatar,” Hammouda says. “The company has operated in Qatar for nearly 40 years, and has a very strong and successful relationship with ENSRV Group – a well-reputed local company.” Hammouda also credits the
company’s “powerful marriage of OEM expertise and local know-how” in securing the large presence it enjoys within the country, highlighting its latest offerings on integration with system controls as part of the sustainable and efficient solution. However, the market still has room for new players, as it continues to cultivate a diversification as part of its preparation for a post-oil economy, with Kumar observing: “I’m quite sure there is room for innovation and new projects to come in. With the 2030 vision, there is a lot of scope for new projects. For someone coming new to the region, the barrier entry is hard. The major challenge in trading side is the lack of affordable warehousing. The cost of warehousing is high in Doha. So, for someone into trading that’s a huge impact, the barriers are definitely high, but once you’re in, you can overcome the challenge.” Nezar, sums up the situation, when he says that Qatar is aiming towards quality, not quantity. “They are looking beyond World Cup,” he concludes. “They are looking towards a legacy.” Cited source: 1. http://www.oxfordbusinessgroup.com/news/ qatar-year-review-2016

Farah, responding to this and emphasising their long-term benefits, said: “If you look at the lifecycle cost perspective, it [inverter-based split air conditioner] has bigger savings than the conventional ones. Although it is slightly higher in the initial
price, payback can be ensured within a year because of higher use.” In addition, inverter-based split air conditioners demand no change in terms of installations, ensuring that the new models can be handled and installed as other conventional splits, with no additional training needed for them to be integrated within building developments.
Is hollow core slab technology suitable for the GCC region? What is the standpoint of authorities?

By Hannah Jo Uy | Features Writer
ollow core slab technology can reportedly play a vital role in the thermal comfort of a development. However, is it able to withstand the harsh conditions of the GCC region? Anbalagan Kandasamy, Managing Partner at Proleed, expressed optimism, saying in this regard: “It’s feasible and there are successful insulations that have been carried out by this technology within the region. They have done it in Saudi Arabia and Muscat, and it has been done in Dubai also for an office building.” While highlighting the energy efficiency feature of this technology, Kandasamy shared his insight on challenges that Anbalagan Kandasamy prevent its widespread use “First thing in my opinion is the challenges related to structural integration of the hollow core technology," he said, “It has to be understood by structural engineers and architects.” He also pointed to the aesthetic limitation that comes with including the technology in the design process, affirming that proper execution would not be possible without the close coordination of architects, structural engineers and MEP specialists. The second challenge that Kandasamy observed is the mood of resistance due to lack of approval from authorities, as it is still a relatively new technology, “I’m talking from the point of view of consultants,” he said. “Unless this system is accepted by authorities, we cannot propose it in future projects. But it’s being taken up by manufacturers. If it gets approved by authorities, we have no objections to including it.”

Panasonic launches eco-water management solutions in UAE Energy efficiency pumps are designed to optimise water resources, says company CCME Content Team
esponding to the growing demand for water pumps in the UAE’s residential sector, Panasonic has introduced a new variety of water pumps designed to optimise water resources, while ensuring sustainable use of energy. The pumps were unveiled at a roundtable held on March 5 in Dubai. Yuu Kai, Panasonic’s Eco Solution Deputy Managing Director for Hong Kong, addressing media while at the event, said, “Designed in Japan, manufactured in Indonesia, our pumps have a high level of durability and are customised for harsh
R
climate conditions, such as the soaring temperatures in the Middle East, which can go as high as 50 degrees C.” Elaborating on the features, Kai said the pumps are dustproof to prevent sand particles from entering the equipment. The impeller, he said, is made of brass, which, he claimed, is anti-corrosion and has a low level of friction, thus making it rust resistant and waterproof. He added that it has a strong delivery capacity to pump water at high volumes. Highlighting the safety measures of the pump, Hidenori

He further added that sometimes in African countries, the supply voltage fluctuates and affects the functionality of the pump, causing a fire risk; hence this feature contributes to the safety of the pump. Speaking on the MENA strategy, Mausham Basu, General Manager of Al Futtaim Panatech, said, “After a collaborative period of 18 months, we now have a value-engineered product line of four models of pumps, ranging from 0.5 to 2HP, addressing mainly the residential sector for now. With our dedicated technical and sales teams, we will add tremendous value to the product.” Al Futtaim and Panasonic Eco Solutions would reportedly also be aggressively launching the product in Qatar. According to Panasonic, the demand for energy-efficient products is growing in the Middle East, with local governments formulating policies focused on energy efficiency and environmental sustainability. In light of this, Panasonic’s Eco Solutions, the company said, are poised to grow 20% in the Middle East region by 2018, with the launch of other eco-solutions, which conform to these policies.
Trane, Dallah enter JV; announce new manufacturing unit
New venture, Dallah Trane Manufacturing will operate out of Saudi Arabia’s western province to speedily serve HVAC customers in the Middle East and Africa region
By B Surendar | Editor
rane and Dallah Trading Company, a subsidiary of Dallah Al Baraka Holding Company, on March 15 announced a joint venture, called Dallah Trane Manufacturing, at a press conference in Dubai. The new company, to be based in King Abdullah Economic City (KAEC), in Saudi Arabia’s western province, will involve a 6,300-square-metre manufacturing facility on a 22,500-square-metre plot, which, senior officials from both the companies said, will become operational in November 2017. The new facility will manufacture Trane’s airhandling unit (AHU), the Quantum Climate Changer, which has an airflow range of
T
1,000-65,000 cfm. It will also manufacture Trane’s doublewall, low-height AHUs, which have an airflow range of 1,0008,000 cfm. Yet another product will be the company’s chilledwater fan-coil units. “We want to have our manufacturing to be as close to the areas [of supply] as possible, given the substantial transport savings we can pass on to our customers,” said Johan Samuelsson, Vice President & General Manager, Trane Middle East & Africa. “We have lower cost to serve, and faster deliverability, which would tremendously benefit our customers. The demand is very strong in Saudi Arabia, and we can now deliver within 2-3 weeks, as opposed to 12 weeks. There are people who are doing that, and we now
hope to displace that and get market-share.” Samuelsson pointed out to KAEC’s brand-new port facility, which he said, hopefully would ease the traffic and provide ease of access to the manufactured goods. Added Mohyuldeen Kamel, Deputy CEO of Direct Investment, Al Baraka Holding Company: “I thank Johan and Ayman [Kamel] for making this dream come true. As one of the leading air conditioning companies in Saudi Arabia, we are happy we are delivering even in difficult years, and this is a new milestone going forward.” Ayman Kamel, Chairman of Dallah Trading Company, further added: “I would like to thank Trane for this facility. We are talking of more than 35

Leakage in ducts – a silent parasite How manufactures support sustainable development goals by minimising leaks By Hannah Jo Uy | Features Writer
eakage in air ducts leads to both energy wastage and higher costs. As such, it negatively impacts the overall sustainability goals of a country. Many manufacturers are, therefore, looking to enhance the quality of ducts to ensure the safety and efficiency of buildings utilising their products. Vivek Unnithan, Consulting Engineer at Prime Air Conditioning Industries, commenting on this, said, “The problems we encounter with ducts with leakage is with insulation. Usually, we find the leakage at the seams of the ducts and the flange system. With rectangular duct systems, we encounter the problems in this area. We can’t quantify it; it’s not something people look at. But with international Green Building, people should be putting their
L
efforts towards minimising it.” Unnithan also provided an insight into how Prime Air Conditioning is addressing this issue. “What we do for Prime [Air Conditioning] is, we provide spiral ducting," he said, “As we have a specific factorymounted ceiling strip that makes the duct system easier to install and it reduces leakage as an additional benefit, because it creates a bubble. The ceiling strip is composed of EPDM rubber, which ensures an airtight and lasting seal. In addition, it has excellent
heat, ozone and weather resistance. The second company, Focus Air Conditioning, has this new flange system tested by the BSRIA laboratory in the UK, and it complies with DW144 standards. Because it is a certified product, we enhance the focus on minimising leakage in this area.” It is evident that ensuring the efficiency of a product helps ensure the competency of the system, and, ultimately, contributes to the over-all sustainable development of a country.
IEQ in hospitality – ‘most challenging sector’ High-occupancy rate makes duct cleaning in hotels difficult By Benwen Lopez | Assistant Editor
aintaining indoor environmental quality (IEQ) levels in hotels in the GCC region is a difficult task, according to IEQ service providers. 8Vaa^c\ ^i ¹i]Z bdhi X]VaaZc\^c\ hZXidgº! AZd Radford, Managing Director of Envida Technical Services, said that this is because, usually, hotel occupancy in the UAE is high, and barely drops from 100-80% in non-peak periods. Elaborating, Radford pointed out that duct cleaning is always challenging in hotels because it requires a shutdown of the HVAC system, and this is not possible even if it has a low occupancy rate. He added: “Although hotels will clean the fresh air systems, they will never usually clean the ducts in the rooms. And this is a critical issue from a guest point of view, because it is the guest who is sleeping in the room.” Suggesting that hotels should consider developing a customised IEQ programme, Radford said: “The occupancy rate between five-star hotels and budget hotels is similar, and it is not very expensive to develop a tailor-made IEQ programme; it can be drawn up in line with a client’s budget. However, we rarely find hotels pro-actively participating in indoor air quality (IAQ) testing programmes and charting strategic goals and a roadmap for better IEQ conditions. You also have some hotels who do participate in a programme, but usually go directly to the laboratories. But the challenge here is that while laboratories do conduct tests and give reports, they do not offer the required guidance to implement the changes, so that the IEQ is improved.” On regulations, Radford said, “The Dubai Municipality does have the Dubai Green Building Regulations, with a section devoted to building vitality and IAQ. However, enforcement of the standard is limited.”

Should schools pay closer attention to the built environment? Improved IEQ results in better scholastic performance By Benwen Lopez | Assistant Editor
rystal Pereira, seven, a student in Dubai, often falls ill with chest congestion and chronic cough. Her parents believe that she usually picks up the ailments from other students in her class. But is there a deeper problem than just kids passing on infections? Studies by experts point out that one of the main contributing factors towards a student’s scholastic performance is superior indoor environmental quality (IEQ). With students, teachers and support staff studying and working in a school building for an average of 6-10 hours daily, risks of respiratory disorders are high, if no attention is paid to the built- environment. IEQ in schools relies heavily on the maintenance of HVAC systems, according to a study carried out by Nazanin Behzadi. The study, conducted across four schools in the UAE, also reveals that children are most vulnerable to health issues when exposed to poor IEQ conditions in schools. Her report shows that since children’s bodies are still in the development stage, they tend to breathe more rapidly than adults, and since they are closer to the ground level because of their height, the inhalation of pollutants, including tiny particles, is more aggressive. The report further says: “They spend most of their time in a school building. Thus, appropriate
C
IAQ for school environment is an exceptionally important matter.” Experts also suggest that a student’s performance is closely related to IEQ. According to a white paper authored by B Surendar, Editorial Director and Associate Publisher, CPI Industry, when a classroom has poor IEQ, it could comprise more than 500 chemicals and microbes and unseen and odourless gases among other dangerous pollutants. The white paper suggests that these cause chronic respiratory disorders, which result in absenteeism, which in turn, leads to the child lagging behind in studies, gravely affecting student performance. However, the scenario can change if schools pay more attention to the builtenvironment of classrooms. Although regulatory bodies do monitor building aesthetics, both IEQ, too, needs to be regulated. The white paper recommends school administrators to “adopt adequate IEQ principles and to embrace strategies and solutions.” Behzadi’s study, on its part, suggests that IEQ is often a forgotten subject, and that prolonged exposure to unhealthy conditions can lead to long-term health disorders among children. Hence, school authorities need to ensure that HVAC systems are adequately maintained on a regular basis.

Acoustics in schools – crossing the sound barrier Greater awareness and action needed, says expert By Benwen Lopez | Assistant Editor
oor acoustic systems impact indoor environmental quality (IEQ) in schools, thus affecting the performance of both students and teachers, say industry experts. Citing a global acoustic study report, Paul Schwarz, Chairman of the Middle East Acoustic Society, said, “There is an alarmingly large number of classrooms within schools right across the fee-spectrum, which have very poor acoustic systems, and poor room acoustics is a constant barrier to effective learning.” Calling it “a big problem”, Schwarz said, “It has been identified as requiring serious consideration and solutions immediately, if we are to improve educational standards, especially as the number of children per class continues to grow, and as school budgets are increasingly put under pressure.” Explaining the dynamics of the acoustic
P
system, Schwarz said that acoustic codes are the driving force behind the system, because they govern the maximum decibel level of noise, ranging from air conditioning units in classrooms to the quality of the walls that segregate the rooms and corridors, including the maximum reverberation time – the length of time it takes for a sound to die in a closed space – in every room. “Hence, regulations place a big emphasis on ensuring that a highquality learning environment is provided for every child in every school, including a greater need for a quality design for children with learning difficulties,” Schwarz said, an area, in his opinion, that needs greater attention. Elaborating on the subject of regulations, Schwarz said: “The good news is that regulations have now been adopted by the municipalities of Dubai and Abu Dhabi. As
of January 1, 2014, it is now also mandatory for all new school developments to comply with UK Building Bulletin ’93 (BB93), which sets out minimum design and performance standards for acoustics in all buildings used for educational purposes, not just schools.” However, despite regulations, in Schwarz’s view, the challenge still lies in implementation and raising awareness. He pointed out: “There seems to be a delay in adoption of these standards by school developers and architects in the UAE, either simply because they are unaware of their responsibilities to ensure this code is adhered to, or they are aware of it but, disturbingly, decide to take their chances, hoping that the local authorities will not check if the appropriate studies have been included in the design process, and so choose to save time and money by value-engineering this step out of the project.”

What does the new UAE Fire and Safety Code mean for the HVAC sector? It will affect bigger buildings, says expert By Hannah Jo Uy | Features Writer
ore than ever, the UAE is dedicated to promoting fire safety, affirming the strategic objective of the Civil Defence department to reduce the incidence of fire accidents significantly during the timeframe of 2017-2021. This was revealed at the recent Fire Prevention Conference1 held in Abu Dhabi to mark the World Civil Defence Day that is celebrated internationally on March 1. The conference highlighted proactive measures towards installation of fire detectors as well as the launch of the UAE Fire and Safety Code, which aims to encourage cooperation among contactors, consultants and residents. With new changes on the horizon, what does this mean for the HVAC sector? Alexander Castellanos, Associate Director, WSP Parsons Brinckerhoff, shared his insight into the impact these changes will bring, saying, “There are two things that will happen: It will affect the amount of locations where you need smoke control, but you can’t say it’s a significant new requirement; it is just clarifying that they need it in more locations but the message of self-control is not going to change. So, it is not like we are going to require new systems; the systems in the market will be in more places.” In Castellanos’ view, the important thing is to properly put to use the equipment available in the market and install them in new locations. “It won’t affect the HVAC industry as a whole,” he said, pointing out that bigger buildings will have a bigger impact.

By Hannah Jo Uy | Features Writer
uilding Information Modelling (BIM) joins the ranks of recent technological innovations that can play a vital role in improving the over all efficiency of various developments. Indeed, there is no shortage of tools that can help raise the standards of comfort cooling in the UAE. However, the question
B
remains: What is hindering the proliferation of BIM and other valuable tools in the design process of buildings? Henrique Pereira, Managing Director at SEABRA Middle East, observed that despite being aware of the availability of BIM, the knowledge gap lies in the clients’ lack of awareness with regard to the long-term benefits of these tools. This, in his opinion, is essentially what is hindering their decision to opt for them, as it means incurring greater cost. Though SEABRA is open to its use, BIM has not been integrated into the company processes at the moment, Pereira revealed. “We need to know what the market requires and what customers want,” he said. “It’s not a question if it is available. It is a question if they are ready to pay for it or not. We are suppliers; we can give it to them and easily fulfil the expectation. But if they are not prepared to pay for it, then we cannot supply them.”

Most of the equipment is reportedly still being sent to landfills. But there is no established procedure in place to confirm whether or not the refrigerants have been removed from the equipment before they are discarded. Thus, in case there are leakages, they could lead to refrigerants being released directly into the atmosphere. It is evident that such equipment require specialised waste management methods to ensure their safe disposal. “There are three aspects to the recycling of HVACR equipment: First is the gases stage, the second is the compressor oil and the third is the metals,” said Stuart Fleming, Managing Director, Enviroserve. The process begins with the removal of CFC and HFC refrigeration gases from the air conditioning units prior to decommissioning, he explained, followed by extracting the compressor and compressor oil and, finally, dealing with the leftover metals. “Why throw it away when you can recycle it?” asked Fleming. Each aspect is crucial, as the gases lead to global warming and ozone depletion, and the oils can seep through the soil to contaminate the water table. However, despite technology and expertise in place to ensure proper waste management, and despite the UAE government’s support Make climate in this regard, a general planning lack of awareness prevails part of an among those disposing of air economy-wide conditioning equipment. strategy “There’s no excuse for the country,” said Fleming. “We do have the facility for all three areas of recycling – the gas, the oil and the metal.” In his view, it is merely lack of EURACTIV Energy education and a case of non@eaEnergyEU conformity to legislation.
The Energy Budget – a book offering critical solutions for global warming In his new book, George Berbari outlines a radical path towards energy efficiency By Benwen Lopez | Assistant Editor
ritten against the backdrop of the acceleration of global warming, George Berbari, CEO of DC PRO Engineering, in his book The Energy Budget, has issued a clarion call for an establishment of a collective approach towards environmental sustainability. The book was released on March 2, 2017 in Dubai, UAE. On the occasion, Berbari said: “Global warming has always been a complex problem, and it is way beyond the understanding of engineers or politicians to explain it to ordinary people. Hence, I have translated this critical issue for commoners, and offered a joint
W
solution.” About the solutions offered, he said: “It is only over the years I developed a singular common solution for global warming, and we can selffinance it by developing an energy budget in every city and country, and across the world.” In his opening remarks at the event, B Surendar, Editor, Climate Control Middle East, and editor of the book, George Berbari said: “George is a rare mind that seeks out solutions in a structured and contemplative way. His is a mind that ponders over social, economic and environment-related issues, always briskly weeding out myths and perceptions to reveal the facts. I appreciate this rare approach to intellectual pursuit, and it is this that shines bright in The Energy Budget.” Speaking to Climate Control Middle East on the sidelines of the event, Anil El Sayed, Managing Director of ACE International Consulting Engineers, said: “We all have to be very conscious about what is going on, and this book will shed some light and be a guide for us, since we are consultants of different trades … and it is one step towards educating all engineers about the risks that we are living in, and we should implement it in our business. This book and similar other books aim towards the same direction, and it is a collective effort, and everyone should work towards this common goal.” On his part, Ashraf Abdalla, Vice President and General Manager (Middle East and Africa) at Johnson Controls, echoing Haq’s sentiments and lauding the work as a good reference book which represents the region, said, that as an industry, there is a tendency to transfer models from other regions, which could be good but may require certain customisation to fit the regional ambient profile. “Hence,” he said, “this book will contribute immensely in sending the message across, because this is not just about cost but it is also about saving the environment.” Raphael Khlat, CEO of Faisal Jassim Trading Company added, “The figures that George speaks of are scary, and governments need to implement initiatives towards this complex problem of global warming, and I believe that this book can be used to achieve the environmental goals.” He further said: “While technologies to achieve high efficiencies exist, it all boils down to awareness. And, as a company, we create awareness among consultants about the efficiencies that we can really achieve using certain technologies, but then, it really lies in the hands of the developer, because it depends on them if they have the will to achieve 80% efficiency or 50% efficiency.” In conclusion, Berbari said: “Through this book, I offer a message of hope that we will not fail in this mission, and we will prevail. However, we do need to accept change, and soon.”

from this pricier option. Paul McGarrigle, Strategic Account Manager Middle East & Africa at Thermo King, affirms this, saying, “Although it is a standard in Europe, it is not currently a standard for the Middle East for the very reason that availability is not high at the moment. Nobody is obliged to use it at the moment, so the suppliers haven’t brought it in the region.” In Europe, the use of refrigerants has been regulated, which has made R452A a necessity, not a luxury. Thermo King continues to advocate the use of R452A in the UAE, through actively reaching out to Dubai Municipality, as well as to other
government entities and decision-makers, to help incentivise its use by highlighting its long-term benefits to the environment, McGarrigle revealed, and added, “I think the Municipality has the right mentality, and they want to introduce process and legislation. As of today, we are still in the early stage of supporting them.” Thermo King, said McGarrigle, remains confident that with proper guidance, in the next few years, R452A can be the new standard for the region. And as for the price, he believed that the volume that comes with increased demand will make the refrigerant more accessible cost-wise.

Countering the counterfeit – the war continues Identify and report, say authorities By Benwen Lopez | Assistant Editor
O
ne of the critical problems plaguing the HVACR industry is the flood of counterfeit products in the market. Experts point out that these fakes pose a serious threat to the environment, economy and to the
consumer. In this regard, Naveen Sivakumar, Marketing Manager at Danfoss, said, “Counterfeit products do not just affect the economy, but there are significant concerns, such as safety issues and the impact on the environment, because they lack the engineering, testing and meeting of specific industry standards.” He added that the fake systems do not have lasting stability. Citing an example, Sivakumar said, “In refrigeration, expansion valves are considered to be the brain of the system, and if this particular valve is faked, it can have adverse effects on the consumer.” In Sivakumar’s view, 95% of the fake products come from China, while five per cent are from Taiwan. Voicing similar concerns, a source from Dubai Municipality
said, “Although the fakes come cheaper than the originals, yet they pose a serious safety issue to consumers and the environment.” On regulations, the source said, “Whenever anyone identifies a supplier of fake products, they should report the person to the authorities, after which, a joint investigation between multiple agencies is carried out, following which, raids are conducted and criminal charges are pressed, if necessary.” Sivakumar, on his part, added that Danfoss, along with the Dubai Police and other government agencies, conducted sting operations in Dubai, and got the counterfeit product dealers arrested. The source also said: “With technology, it has become easy to produce counterfeit products. However, the composition of raw materials in these products is of inferior quality.” On spotting fakes, the source suggested that consumers should look for identification marks, irregularities in engineering designs of the finished product and differences in logo designs.
Montreal Protocol: How prepared is the hospitality industry in the region? Basic ethical education is mandatory for consultants, contractors and suppliers, says industry insider By Benwen Lopez | Assistant Editor
t has been more than five months now since world leaders and climate experts, while in Kigali, signed the Montreal Protocol to phase out hydrofluorocarbons (HFCs), globally. Although the programme is being implemented in different phases worldwide, the question is: What is the level of acceptance and implementation by the hotel industry in the GCC region? Speaking on the measures taken towards addressing the issues regarding HFCs, Ramamurthy Thevar, Group Director of Engineering of Abjar Hotels International, said: “Hotel engineering directors and chief engineers do address the need for arresting global warming as well as lowering HFCs, but as it is barbed- wired from execution and implementation, it either slows down or doesn’t move. However, this can be effective if law enforcement agencies, owners and financiers are involved.” Regarding the onus that needs to be

shared by others, he said: “Engineers are, indeed, very proactive. But this should also start from the design consultants, architects, builders and owners at the design development phases, where the building envelope designed is built to utilise half the energy during the construction phase itself.” Suggesting a strategy towards the phasing-out process in the GCC region, Thevar said: “To meet the phasing-out deadlines, firstly, the alternative steps need to be taken to reduce the current and increasing levels of carbon dioxide-equivalent emission, then retrofit with alternative solutions instead of HFCs.” On retrofitting old buildings, Thevar was of the opinion that old Existing Buildings can be enveloped by way of adding solar reflective coatings, which can reduce heat
penetration into the building, thus reducing the cooling load by 30%. Suggesting other retrofit methods, he said, “Various other methods, such as full solar cooling and heating, hybrid cooling technologies and other non-toxic solutions are also available.” Stressing the need for creating more awareness on the issue in the industry, Thevar said, “Basic ethical education is mandatory for consultants, contractors and suppliers, and they should not just have a money-making attitude.” Thevar added that as an organisation, the engineering team identified in the chain of nine hotels, that certain MEP designs had been overdesigned, and upon evaluation, they decided to scale down the design from a six-pump operation to a one-pump operation.

thus giving them data that can be used to improve their expertise and future projects. Younes pointed out that several factors, such as energy efficiency and the functionality of the HVAC equipment are monitored during this period, and the data collected become an excellent resource. He said, “While it is up to the consultants to offer the Soft AVcY^c\h ;gVbZldg` Vh Vc option, it is ultimately up to the clients to accept it, since many customers do see this as an added cost due to the additional burden of fees, such as the Estidama and Green Building costs.” Younes further suggested, “Engineering and consultant communities should

FIDIC: A complex ‘jigsaw’ puzzle for the GCC region A uniform code of contract needed By Benwen Lopez | Assistant Editor
espite the complexities in the current use of FIDIC (The International Federation of Consulting Engineers) contracts in the GCC region, there has been a ‘hesitant’ support among experts in the UAE towards implementing a localised FIDIC contract Regarding this, VS Chandra Sekhar Reddy, CEO, Elemec Electromechanical Contracting, said: “Any documentation can be localised. However, the implementation is the crucial factor, because currently, each individual developer and contractor is re-drafting FIDIC for their own convenience and, ultimately, it is the MEP industry that is at the receiving end.” Reddy added, “We do understand that FIDIC is for builders, but overall there can be an improvement. However, it needs to be honoured and implemented, and nobody should be allowed to re-draft the content of the document to their advantage.” In Reddy’s opinion, if a local FIDIC is to be drafted, it should have a strong legal backing to protect the client, the contractor and the consultant. Voicing similar concerns, another industry expert, Ramesh Kumar,

said, “While a localised FIDIC is required, yet there is a long way to go because of the different complexities of the issue.” Highlighting the complexities, Kumar pointed out that while most businesses use the 1987 version of FIDIC in Dubai, the 1999 version is used in Abu Dhabi. Differentiating between the two versions, Kumar said, “The 1987 version offers more protection to the client, while the 1999 version offers the balance, where all parties involved are protected.” On the flip side, in Kumar’s view, the government version of the ‘bespoken contracts’ derives its data from the current two versions to suit particular requirements; hence there is no uniformity in the market. Kumar indicated that if FIDIC is localised, then it should follow a uniform code of contract endorsed by government bodies, and followed strictly, else, its purpose would be defeated.

Temporary turbulences expected By Benwen Lopez | Assistant Editor
ith the GCC states all set to roll out the value-added tax (VAT) in January 2018, the HVACR industry anticipates a temporary drop in business. Biju Joy, Financial Controller of Refrigeration Equipment Enterprises, said, “Although there is no clarity yet on how VAT will be applied and how it will be calculated, we do anticipate a slowdown of business during the initial three months, but we are positive to bounce back.” Joy also pointed out that quality, consistency, efficiency and sustainability, according to industry standards, are the key factors to sustain during the time of market changes. Sharing Joy’s concerns, another industry expert, Rajendra Kumar Verma, Divisional Manager at Technical & Trading EST, said, “The GCC region has so far been tax-free, and with the introduction of five per cent VAT, there is bound to be some market turbulence, because of consumer reaction, but for a temporary period.” He further said: “Usually, the validity of our quotes is 1-3 months.

Gen Next HVACR businesses in India form a group Aim to establish bigger footprint in the Middle East and globally, members reveal to Climate Control Middle East By Pratibha Umashankar | Associate Editor
he Gen 2.0 of HVACR businesses in India, some of whom already have a substantial presence in the GCC region, are looking to come together for informal chats to swap notes on the sector’s business scenario in the region, Climate Control Middle East has learnt. “The HVACR Gen 2.0 is a group, whose members are the second generation of family businesses in India in the field of HVACR,” said Varun Pahwa, speaking to Climate Control Middle East. “The members are a mix of consultants, contractors and suppliers.” Sharing their initial thoughts, a few members of the informal group said that they are chalking out a programme to get those interested to start contributing ideas on the aims and objectives and what the group can collectively accomplish. The rationale behind forming the group is two-fold, they revealed: Within India, they want to get to know each other better, as

the aspiring members have inherited the industry and have a lot in common in terms of background and knowledge from Gen 1.0, as their parents have worked together. They, therefore, believe that forging new bonds and reinforcing old ones among the next generation could prove rewarding, both for the members individually, and the HVAC industry as a whole. Secondly, they want to turn their gaze on the industry globally, by networking with family HVACR businesses in the Middle East and Africa region, as well as Europe, South and South East Asia, to have future alliances, partnerships, assistance for market entry and opportunities, both for services and products through closer and frequent introductions and contacts with like-minded people and/ or businesses, and have access to countryspecific HVACR market and knowhow. The long-term goal of the group reportedly is to, as SMEs, organise
programmes to assist and inspire growth and build on the foundation laid by Gen 1.0 and enjoy the growth India is touted to witness through 2025 and 2030, establish ‘Brand India in the HVACR space and encourage ‘Make in India’ through potential alliances. The avowed lofty aims of the group also include encouraging best business practices, products and services and set the bar high. “In April, members of the HVACR Gen 2.0 will be meeting in the Indian state of Goa,” Pahwa informed. “The group plans to meet again during The Big 5 Dubai 2017. Considering that many of the businesses have a strong presence in the Middle East, we want to have a Middle East group going,” Pahwa said, and added: “There’s no structure to the group. Business is not the driving force. It’s about the future of the industry and how we can shape it together. We are in it for life.”
Artificial Intelligence – is the HVACR sector catching up?

rtificial Intelligence plays a key role in enhancing the functionality of HVACR systems, mainly because of the data it shares so that appropriate action can be carried out. However, the big challenge is whether we are progressing fast enough to catch up with Artificial Intelligence or not? “Artificial Intelligence has been around for 20 years; however, before it can be used, it needs implementation,” says Vijay Kumar, President – International at Cylon Controls. He points out that the lack of growth for its use is mainly due to lack of awareness about it. Kumar adds that although Artificial Intelligence is available for different systems, such as the Building Management System and HVACR system, yet there does not seem to be a will to implement it aggressively. In conclusion, Kumar cites the lack of training as the main reason for failure in deploying Artificial Intelligence in the HVACR sector.

In the case of big chillers (of 150-4,000 TR capacity), Trane is using R-1233zd and R-514a, Thompson said. “Our drive is towards non-flammable HFO solutions, which are more efficient,” he said. “They will be expensive, but we expect prices to come down in the coming years.” Some products, Thompson said, will be easier to transition. ¹>c i]Z XVhZ d[ aVg\Z"idccV\Z X]^aaZgh AI8h ! ^c i]Z cZmi ild years, you will see chillers with new refrigerants, which will have better efficiency,” Thompson said. “Trane has been able to develop chillers that are 10% more efficient and with a GWP that is less than two.”
