n the span of three weeks, two personalities on completely unrelated occasions spoke on the virtues of the ‘Wait, watch, act’ approach. Dr Nacer Achaichia of Honeywell, while participating in the 3rd edition of Refrigerants Review conference on March 24 in Dubai, said: “One of the mistakes Europe made when they moved from R-22 was to adopt R-404A, which has a very high global warming potential (GWP). So, it is good the Middle East has come in late on the action that needs to be taken, because you can learn from the mistakes Europe made.” The second personality was Ismail AlMarzooqi, the Chief Executive Officer of South Energy, the newest District Cooling utility in Dubai. He spoke of how South Energy has evolved a model based on watching and learning. He elaborated on how he had spent years observing a common trend in the GCC region of building ‘monolithic monsters’, a term Ken Currie, a senior industry professional in the region, used to characterise large District Cooling plants. Out of that learning, AlMarzooqi said, he decided to take the route of building plants that are around the 20,000 TR mark, and establishing a network of such capacities that allows for distributed cooling. Such a model, he said, works well for him in mitigating risk and optimising cost in the objective of cooling the facilities that make the Dubai South project, which spread over an area of an astonishing 145 square kilometres, is arguably the largest land area by a single developer. In mid-June, we shall be conducting the next edition of DC Dialogue, one of the oldest meetings of District Cooling professionals in the region, with the first edition held in May 2007. AlMarzooqi, it is expected, will be a participant and will elaborate on his approach. Broadly speaking, the conference will discuss the policies and technologies that can help reduce primary energy use by 70%. Al Marzooqi’s expected participation is all the more relevant, because at South Energy, the move is to harness and use solar energy to meet at least five per cent of the requirement for operating the entire District Cooling regime. Now, five per cent may be akin to a drop in the ocean, but it is a start and perhaps a harbinger of something exciting.

he 3rd edition of Refrigerants Review, which took place on March 24, 2019, at the Falcon Ballroom, Le Meridien Hotel & Conference Centre, Dubai, UAE, examined the refrigerants emerging in the landscape and fostered discussions involving government bodies, building owners, consultants and contractors in the Middle East on how to time a switchover to a set of refrigerants that are specifically suitable for high-ambient conditions, while simultaneously addressing the need for aligning with global efforts towards mitigating climate change.
24 MARCH 2019 FALCON BALLROOM, LE MERIDIEN HOTEL & CONFERENCE CENTRE, DUBAI, UAE
n January 1, 2019, the Kigali Amendment to the Montreal Protocol, ratified by 65 countries (as of December 21, 2018), came into effect. The amendment aims to reduce HFCs in air conditioning, refrigeration and other related sectors by more than 80% in the next 30 years. A UN report on this says: “If fully supported by governments, the private sector and citizens, the Kigali Amendment will avoid up to 0.4 degrees C of global warming this century while continuing to protect the ozone layer.”*
‘If’ is the operative word in the UN statement. Undoubtedly, there is a growing consensus among the international community on the need for urgency in addressing climate change; however, the ‘right path’ in terms of climate action remains a highly debated topic, especially in certain countries. Classified under the Article 5 Group 2 of the Amendment, Bahrain, India, Iran, Iraq, Kuwait, Oman, Pakistan, Qatar, Saudi Arabia and the United Arab Emirates were given a 2028 freeze date for the import and consumption of HFCs, four years later than the 2024 deadline given to other developing countries, in recognition
Following the enforcement of the Kigali Amendment to the Montreal Protocol, stakeholders from the international HVACR industry are left having to navigate an increasingly complex refrigerant landscape in view of looming targets. Although for many countries in the Middle East the freezedate for the import and consumption of HFCs, set at 2028, is some years away, decisionmakers reflect on opportunities for futureproofing equipment and buildings, with an eye on managing cost and ensuring safety. Will the extended deadline given to these Article 5 Group 2 countries serve as a cushion for complacency? Or, will the region use the time to get ahead of the curve? Hannah Jo Uy draws key insights from participants of the 3rd edition of Refrigerants Review, held on March 24, in Dubai…

“Independent tests were conducted on RS-70 and six other refrigerants under the same conditions. The results demonstrate that RS-70 has good energy efficiency and provides high cooling capacity with a lower power input. So, it can be used satisfactorily as a replacement for R-22.”

“Our protocol to prevent leakage involves having an in-house contractor staying with us 24/7, and it is part of our annual planned preventive maintenance. Part of our daily task is to do leakage inspection. Due to geographic reasons, we are receiving salty, humid condensation, which enhances the process of corrosion of the pipe, so we replace it every 4-5 years to prevent leakage. We are, unfortunately, using an old method for leakage detection for daily inspection. We don’t have a real defined standard given to us to follow, when it comes to refrigerant management, but we really care about global warming and the environment. We are trying to keep inspection of the gas going to prevent it from leaking. We recently received a letter from a local agent that R-22 will be pushed out and they cannot support us in case of any shortage. It will be at the end of 2020.”

The challenges in Lebanon are very common to other countries, such as lack of awareness of the efficient cooling opportunities, costs, lack of expertise, and of legislation and enforcement. Other countries go to product standards, MEPS and product labelling. Evidence shows prices declined when energyefficiency standards were enforced. Studies showed that the decline in prices is attributed to standardinduced innovations and not market competition. Despite impressive progress on uptake of standards, many countries have weak or no energy-efficiency standards, making them vulnerable to dumping of wasting equipment.”

“When we do renovation for R-410A, we make sure the contractor complies to recover [the refrigerant] with a certified facility, and to give us the certification that it has been recovered. That is an important step we are doing, so the refrigerant is recovered and disposed of [properly].”

(A collection of quotes from the 3rd edition of refrigerants review on March 24, in Dubai) R-22 is the most used among HCFCs in Oman. Its consumption has increased from 321.82 MT to 535.1 during the period from 2007 to 2010. There was a sharp increase from 2008 to 2009. The major use of HCFC is in the servicing sector, where the servicing of small air conditioners accounts for a substantial portion of the overall consumption. The baseline of the HCFC consumption was established as 31.5 ODP tonnes by the Government of Oman, using the average of the 2009 consumption of 30.7 ODP tonnes and the 2010 consumption of 32.2 ODP tonnes. HFC gas emissions in Oman was reported at 332 in 2010, according to the World Bank report. HFC 134a is mainly used in the air conditioning sector.
While HFO chillers options are available with equipment suppliers, the transition to this refrigerant option is expected to pick up gradually. The reason for the delayed transition is the competitiveness of the HFO chillers in Middle East conditions and availability of the complete range – not all suppliers have the product in the portfolio.

So, those are the larger chillers, and before the agreement, we were using the refrigerant R-123, and since that time we have rolled out two new refrigerants, R-1233zd (E), which has a GWP of zero, and R-514a. We have got a window with R-1233zd (E) machines, which we could reuse in our existing portfolio. For both refrigerants, the GWP is less than one; and they are non-flammable. Another is that R-134a is used in the rotary chiller and goes up to 400 tonnes. Today’s refrigerant, for instance, is R-134a, and the next-gen refrigerant would be R-513A, and its GWP is under 700. The CenTraVac chillers have a low-pressure refrigerant and are different from the medium-pressure refrigerant chillers. The medium-pressure refrigerant chillers go from R-134a to R-513a. And for the R-513a, the GWP is under 700, so we would probably have to go one more time, but today we have 700, which is a big step forward from where we are.
When do you plan on making the further transition? Right now, there’s no pressure in North America to go lower. We led the way with R-513a, so in Europe, we do R-123ze, and its GWP nears zero, and that hasn’t made it here yet.
Codes will change in time for California, but not before that. It is a three-year cycle for them to change, and we’ll be ready for California and will make a choice between the three non-flammables and the other refrigerants under consideration. We are evaluating three non-flammables right now and will make a decision soon.
You’re saying there’s no pressure, but wouldn’t Trane want to take the initiative of going lower? Chillers are likely to get more expensive, so we will likely have an alternative before we have to but not at this time. And right now, no competitor is selling the ‘ze’ refrigerant here in North America, so where we are active right now is with R-410a with residential units and with unitary products. It looks like California is going to help us change with some regulation, and several other states like Washington, Massachusetts, along with four others are going to ask us to go faster. And so, we have several alternatives – three of those are similar in terms of GWP. Once you get a little below 700, all are slightly flammable, which is not allowed by the Building Codes. I’d say we’re evaluating the refrigerants, and we believe the Building
The leadership in the United States has a different opinion on climate change. How much is that influencing your research and development as a company at a national level? It’s not affecting us, because we listen to our customers. And our customers need green alternatives. There are large companies, who are all ready to make a climate commitment. We’re going to go based on our customers and on the market.
Could you elaborate on Trane’s initiative with regard to 3D printing? I’ve been out of project management for two years now, so what I tell you might be old, but we were using 3D printing for prototyping in design. For instance, 3D-printing a new control panel for a new product, wherein we print a new product or a new component, as opposed to ordering it.

Strategic urban planning iS critical for SuStainable development
Rapid urbanisation, which restructures economies and the lives of billions of people, poses significant challenges, says Pradeep Singh, Manager – Business Development & Technical, Etihad ESCO
ore than half of the global population live in urban areas today, with millions of people being added to this number every week. Urbanisation in developing countries, which restructures national economies and lives of billions of people, is a defining feature of the 21st century and is seen as the most remarkable demographic shift our century has witnessed. Cities are undoubtedly the nerve centres of economic growth. They play a vital role in the development of nations and lives of people and have immense potential to achieve the UN Sustainable Development Goals (SDGs). Nevertheless, the rapidity and scale of urbanisation present significant challenges, which include the need for affordable housing, sustainable and comprehensive transport systems and related infrastructure, basic amenities and employment. The unprecedented growth in terms of new urban built-up area calls for urgent action from all stakeholders. Climate change being observed globally, and its current and future consequences on life, property and progress pose major challenges for human society over the next century. If no significant investments are made to enhance the resilience of urban centres around the world, climate change may result in urban population living in poverty, according to the United Nations. Cities consume two-thirds of the world's energy, considerably increasing global greenhouse gas (GHG) emissions.
The physical form and land use patterns of cities cannot be changed once they are built, and they grow in ways that are not harmonious with the ecosystem surrounding them. Unsustainable sprawl, an outcome of rapid, ill-conceived development, hinder the accomplishment of development objectives. There are several misperceptions associated with urbanisation and sustainability. Urbanisation, by itself, is not bad, and the migration of people to cities becomes a burden only if they are ill-prepared to accommodate a spike in the number of inhabitants. Planning and preparation, therefore, are extremely important. Cities can be eco-friendly and costeffective, if planned and budgeted correctly. This can be achieved through successful public-private partnerships, investments, foreign assistance and joint efforts. Growing prominence of energy service companies in urban markets also plays a crucial role in managing energy consumption, while simultaneously contributing to sustainable development of these cities. Sustainable urban management and planning is imperative, regardless of a city’s reputation as a booming economy or the speed with which it is growing. Furthermore, sustainability and better livability can be achieved at any point of a city’s development in an inclusive manner. Also, it is important to remember these changes cannot be introduced overnight. This transformation is a cumulative build-
up, based on behavioural changes or changes in our social attitudes. Creation of a sustainable, healthy, livable space is everyone’s responsibility. Partnerships and interactions in grass-root levels and engagement are necessary to build people’s faith in governance systems, teamwork and collaboration, needed for the success of such efforts. Development must be driven by affordable, accessible and sustainable energy resources to ensure a viable, healthy and environmentally sound future. Some developed nations have already managed to separate economic growth from energy consumption to cut down resource inputs and to alleviate environmental impacts. Increased adoption of renewable energy in urban settings is highly significant as it helps in meeting rising urban energy demand and achieving reduction of emissions. Also, renewable energies are expected to become more efficient, user-friendly, costeffective, accessible and sustainable with the advancement of technology. We are optimistic that this will further drive the adoption of renewable energy. There is no denying that sustainable urban energy is the future and is the only means to bridge the gap between urbanisation and sustainability. Hence, it is time we focus on the bigger picture.

Dr Udo Huenger, BASF
SuStainable SolutionS, digitaliSation are the way ahead Dr Udo Huenger gives an overview of the company’s roadmap, following his new role as Vice President, Middle East, BASF By Ranjana Konatt | Features Writer
s the new BASF Vice President for operations in the Middle East, could you take us through the roadmap of the company? BASF is an active partner in the industry in the UAE. We have been present in the region for over a century, and our office in the UAE dates back to the 1970s. You can, therefore, say that we are deeply rooted in the region. In addition to our regional headquarters in Dubai, we have offices in Abu Dhabi, Al Khobar and Cairo. In the UAE, we operate a state-of-the-art polyurethane system house in Dubai Industrial City and a production facility for construction chemicals in Dubai Investment Park. Our construction chemicals business also has sites in Saudi Arabia, Jordan and Egypt. In Bahrain, we operate a production facility for customised plastic additives. We have always aligned our business with the strategic vision and economic agenda of the governments in the region. What the visions have in common is not only a strong drive towards growth and economic diversification but also the realisation that having a commitment to sustainability is key to achieving long-term growth. We see unprecedented opportunities in various sectors to support these national priorities, and hence, we share our knowledge and expertise. After all, our commitment to sustainable solutions is anchored in the corporate purpose of BASF, which is to create a sustainable future.
To what extent is BASF reinforcing its commitment to sustainability, innovation and digitalisation, while also expanding its footprint across the region? Our new strategy, which we presented in November 2018, aims at profit and a CO2-
neutral growth. This means that we will decouple our greenhouse gas emissions from organic growth. To achieve this, we will improve the management, efficiency and integration of our manufacturing sites, and wherever possible, we plan on purchasing a greater share of electricity from renewable energy sources. We have already reduced emissions by 50% in absolute terms, compared to 1990 levels, while doubling our production in this period. In addition, we are working closely with a number of relevant stakeholders to drive sustainable water action and have been awarded a top ‘A’ rating by the international organisation, CDP, formerly the Carbon Disclosure Project. We also want
contributes to climate protection and energy efficiency. Another example is Elastocool, a system made for the insulation of fridges and freezers. The material has a low-thermal conductivity by approximately 0.5 mW/mK, which enables the achievement of energy classes A++ and A+++. The fast cycling time leads to higher output in production, while high compressive strength values lead to lower material consumption per unit. In addition, digital solutions are helping us achieve our sustainability-related goals. Digitalisation presents opportunities, and by using digital technologies and data, we are able to create additional value for our customers and increase efficiency along with the effectiveness of our process. Digitalisation makes our business smoother and, eventually, makes it cheaper.
You mentioned that there is a strong drive towards localised, advanced manufacturing. What are the challenges you foresee, and how do you plan on tackling them?
Dr Udo Huenger
to grow our share of so-called ‘accelerator’ products, including in the Middle East. Across all customer industries, we have identified 13,000 accelerator solutions. These are products that have made a substantial contribution to making the value chain more sustainable. An example of an accelerator product that is performing very well in this region is Neopor, an insulation material that offers improved insulation performance and
When we look at Egypt, a key market in our region, we are increasingly serving local customers, whereas, in the past, a large part of our customer base was multinationals with a presence in Egypt. Other countries in the region, including countries in the Gulf, are also moving in a similar direction. Therefore, I see opportunities for BASF, rather than challenges. One driving factor will be localisation. We are already producing locally and will expand this in the future with the mixing, blending and packaging of materials. Local storage is also becoming increasingly important.

the impact of EMR and how to minimise it. On our part, we have already reached out to several corporates and universities for awareness programmes.
Do you believe that end-users are willing to invest in technology and HVAC equipment, so as to contribute to bettering IEQ? What are your observations? The concept of Geopathic Rectification or Electromagnetic Rectification is fairly new knowledge in the region; however, we are beginning to see more acceptance of this science. People are applying the concept personally and are noticing positive changes in their health, well-being and performance, and an increasing number of people are considering this as an option, convinced that the IEQ would be enhanced. From our experience, our clients are quite open to Rectification. Now, the new thinking is that Smart Buildings should be well-equipped to counter the EMR and Geopathic Stress and their adverse effects.
Are we neglecting or ignoring the impact of Electro Magnetic Fields (EMF) on our body? What action is being taken from a global standpoint? The most integral factor overlooked is the effect of Electro Magnetic Fields (EMF) in office environments. EMF crosses 528 hertz, where plants manufacture oxygen and release carbon dioxide. Therefore, if we are sitting in structures with over 3,000 hertz, we are actually exposed to very high negative energies, so effectively we can’t completely ‘Go Green’ until we counter this element. While the knowledge of Geopathic Stress Rectification is widely accepted in Germany, there are no structured facts or figures on how many buildings are Geopathic
Stress-free. However, while studying in Australia to be a building biologist, I found many students deeply interested in such studies. World over, there are several products that are manufactured for Geopathic Rectification and Electro Magnetic Rectification. For example, there are curtains that can block EMF, or mattresses that are fluffed up with 36,000 litres of oxygen as a replacement for spiral beds, or even paints that neutralise EMF in structures. The GCC and Middle East region need to look at sustainability with the
knowledge of Geopathic Stress Rectification and Electro Magnetic Rectification. Smart buildings cannot be completely Smart without sustainability, and we need to focus on ways to counter GS and EMR. For example, in many countries, WiFi and EMF exposure is limited and gadgets, such as iPads, are completely banned in schools and other public places. We need to incorporate these values, along with protecting our structures against EMR and GS. The visionaries of the region have put every effort to have growth with
sustainability hand-in-hand; however, itâ€™s up to people to choose and not use these smart gadgets excessively, as they will create an imbalance in our well-being. The awareness of Geopathic Stress and Electro Magnetic Stress is very relevant, and the solutions are available, especially in the West, which we can adapt for the United Arab Emirates.

We have devices that can communicate, but you need to pair the devices first. Yes, it is true, you can hack the signal, but we have the ability to limit the range of the signal. Wifi are spread wider than Bluetooth, so, the chance of doing something with a Bluetooth is much smaller, and you might need to be in the building. We regularly engage hacking companies to hack our systems, and based on their reports, we modify. We have a security team that takes care of us.

If you are still concerned, you can remove the display, and there is no power, and so, there is safety in that. We offer remote support through the app. We can remotely see what the drive is doing. We try to put additional safety measures. ABB is a very motivated company when it comes to digital solutions in the electronics industry. I am very comfortable with the safety we have. We can address the concerns our customers have and manage that. In a sensitive industrial environment, like the manufacturing of semiconductors, I would be very cautious about using wireless. But if you are looking at our industry, we are talking of services, and central infrastructure of air control systems are not going to go wireless.

THINKING IN MULTIPLES I
have been in the HVACR industry for 17 years and witnessed how the AC industry, in general, and Variable Refrigerant Flow (VRF) systems, in particular, have evolved over the last couple of years. The year 2008 was when the United Arab Emirates started looking at implementing sustainability in the construction industry. Dubai and Abu Dhabi were at the forefront when it came to walking the green talk, with the introduction of Green Building regulations like Estidama. MEP consultants and local developers quickly understood the social and environmental responsibility required of them and started looking at energy-efficient AC systems in their projects. That’s when everybody started looking at VRF systems as one of the obvious solutions. It still wasn’t easy-going, though. I quite vividly remember the time when I used to present VRF technology, only to hear consultants and contractors say that it would not catch up here, as the initial capex outweighed the sustainability and lifecycle costs. They were right as, initially, the cost of VRF systems was high, due to a limited number of VRF suppliers. To counter that, we as suppliers had to go to lengths to explain how VRF systems would be economical from a holistic – lifecycle cost – perspective. After years of pegging away, today, VRF systems are viewed as one of the preferred choices in low-rise apartment buildings. There is no need to explain the basics of VRF systems, as most of the consultants/ developers are well-versed with the technology. But of course, we need to grow further. And for this, let us consider low- to midrise apartment buildings (2-12 storeys).
Dharmesh Sawant, pointing out to the limitations of installing one VRF outdoor unit per apartment in highrise projects, proposes the approach of multiple apartments connected to one VRF system and shares the benefits of this arrangement for stakeholders...
So far, most of the developers have been showing a preference for one VRF outdoor unit per apartment. The design eliminates the number of outdoor units on the roof by 50% on an average. This means saving valuable real estate footprint in the roofspace area, lower pipe lengths between outdoor and indoor units, lower connected electrical load and lower operating cost for the tenants. However, there is a downside to it. Most of the outdoor units for such a type of application are of smaller capacity, usually adopting single compressors. Any failure in the compressor would lead to the failure of the AC system for the whole apartment. However, the probability of such an occurrence is very rare, as the inverter compressors are more stable, and there are low failure rates in tropical climatic conditions. Another drawback is that we cannot take any diversity into account with such a small capacity (7–20 kW), defeating the very purpose of the VRF technology. The situation is further compounded by the fact that lately, the higher supply in the property market and an increase in land prices are putting pressure on the selling price, and
many developers are looking to go vertical. The choice of AC systems for a developer of highrise residential buildings (12-25 storeys) is either an air-cooled chiller or a VRF system. In today’s challenging times for the construction industry, VRF becomes the obvious choice, as it offers lower capex and opex compared to its counterparts. But, as explained earlier, if we adopt the current design of one VRF outdoor per apartment, there are several limitations. Having too many outdoor units on the roof (the number of VRF outdoor = number of apartments) will put too much pressure on the designers/installers to accommodate all the utilities on the roof. Longer piping and cabling lengths will be required between outdoor units on the roof and the respective apartments, eventually increasing the piping, insulation and cabling cost. No diversity is applied, and the outdoor capacity is the same as indoor units. This leads to an overall increase in the capacity and eventually leads to increased connected electrical load. A final limitation is that there is no redundancy. The one big advantage of challenging times is that it makes the engineers think and come up with innovative ideas. In order to counter the aforementioned limitations in some high-rise projects, the proposal I wish to make is for multiple apartments to be connected to one VRF system.
BENEFITS FOR BUILDING OWNERS So, what are the benefits for building owners through such an approach. Typically, they would include a reduction in the outdoor space that would need to be allotted – and this would be a 60% reduction. With this approach, instead of one VRF outdoor unit per apartment, the whole floor can be connected, and generally, these are top discharge outdoor units. The units can be located much closer to one another, compared to side discharge. The saving in the roof can provide space for a rooftop swimming pool, garden or solar panel installation. There can be a reduction in the electrical installation cost. With one whole floor connected to one VRF outdoor unit, diversity can be applied,
as all the apartments and all the rooms will not operate at the same time. This offers lower connected electrical load by 10-15% compared to one VRF outdoor per apartment. This can greatly reduce the connected fee. Also, since the outdoor units are connected to the building ownerâ€™s DB, there is no need to run the power cabling between each apartment to the roof. This reduces the electrical cabling cost. This can result in lower operating cost. Annual maintenance cost for this arrangement is 15-20% lower compared to one VRF per apartment, owing to fewer outdoor units.
BENEFITS FOR CONTRACTORS The benefits for contractors would include reduction in the installation cost. Fewer outdoor units would greatly reduce the piping, control cabling lengths and number of circuit breakers. Additionally, there would be a need for fewer Sub Main Distribution Boards (SMDBs). Over and above that, the AC installation work would be much faster,
with fewer outdoor units and smaller piping lengths.
BENEFITS FOR ARCHITECTS AND CONSULTANTS The benefits for architects and consultants would include relative simplicity in design, as it would be easy for the consultants to accommodate fewer pipe risers in shafts and other services in them. And fewer outdoor units on the roof would mean a significant reduction in costs related to the civil foundation. An added benefit would be fewer challenges in deciding the electrical and piping routes.
BENEFIT FOR THE ENDUSER The benefit for the end-user is that of redundancy. Since the whole floor is connected to one VRF system, it generally has multiple modules (3-4 per system). Even if one module fails, there would be two or more modules available to give sufficient cooling to all the apartments.
LIMITATION IN THIS ARRANGEMENT There is, however, one limitation in this arrangement. The AC electricity will be billed to the building owner, since the outdoor units are connected to his DB, much like the case with a chiller. However, all VRF manufacturers have their own billing system, which helps in distributing the proportional AC electrical consumption to each tenant. The building owner also has a choice of recovering the AC consumption charges, either as a service charge or as part of the rent. A further means of mitigating the limitation could be for the authorities concerned to introduce a standard to recognise or formalise a uniform billing methodology for all VRF manufacturers.

For example, ENOC is established with ‘ENOC Design and Procurement Standards for Energy Efficiency’ in 2016, which will precisely guide the efficiency parameter requirements of each refrigeration process to be implemented. Third, country certifications, like ESMA in the UAE, APEX, UL/FM, EN, or any international certifications need to be implemented. For example, refrigeration units’ energy parameters shall be certified by the local body, ESMA. Finally, there are design codes and standards, such as ASHRAE, API, ASME and TEMA. In O&G, due to the above rigorous approach, conceiving the technical parameters of a refrigeration technology is completely unique and customised. The Middle East region has many specialised consultants who can propose, design and develop the engineering for innovative ideas and new technologies. However, there is a scarcity in skilled contractors, who can effectively deliver the requirements of the O&G sector across the Middle East, in terms of detailed engineering, installations, commissioning and, more importantly, maintaining the innovative refrigeration technologies for a life span. It is necessary to call for training and workshops on new refrigeration technologies in the market. Consultants and original equipment manufacturers need to work together to offer training on new installations and operational challenges for installers and operators in the marketplace.

WORLD EXPO STRENGTHENING DUBAI AS A REGIONAL HIGHPERFORMER Dr Marcus G. George, CEO, Partner, Engineering - Consortium Consulting Engineers, highlights the trends influencing growth within the construction sector, in addition to how Dubai can gear up for the upcoming World Expo 2020.
hat are the factors contributing to the growth of the construction sector in the UAE, and what are the aspects that make the sector resilient?
The construction sector in the UAE is stable, because it is encouraged by the Ruler’s wisdom. A major contributor to the sector’s growth is the responsiveness shown by the authorities and their support and encouragement to promote the construction sector. The UAE Government’s guidelines and policies help in providing much-needed flexibility, further enhancing the construction sector. It is easy to approach the authorities concerned to resolve the problem. In addition, Dubai and its strategic location, the great infrastructure – the modern roads, ports and airports – all help the construction business grow and develop.
In the UAE, are real estate developers better placed to withstand the constrained financial climate, as compared to contractors? What strategies have developers adopted to be able to sustain their business financially? Developers are reasonably well-placed to withstand the difficult financial climate, as they are allowed to collect money from prospective investors, provided they sell. Their initial investment will be limited, and the collections from the buyers can be used as per the guidelines laid down by RERA (Real Estate Regulatory Agency). Developers are intelligent and smart, they know the market trend, and can identify the location, the type of project and the price-band ‘in demand’ and, accordingly, can address their strategies. With costs being more or less stable, developers can closely monitor their costs, variations and the progress of the work; as a result, they can be in a better position to sustain themselves. Further, developers with financial muscle can further improve on their project quality and standard, which enhances their reputation. New products, technologies and new execution methods are strengthening developers.
Dubai is considered a regional high-performer, as it prepares to host the World Expo 2020. What is in store for the construction industry? What kind of an upward graph is the construction industry likely to experience? The World Expo is a significant international event, last held in Milan in the year 2015. This is the first time an international event of this magnitude is taking place in the Middle East, especially in Dubai. It will definitely be motivation to the region and to Dubai, in particular, and will further enhance tourism in the UAE. In addition to its busy schedule of activities and international events, the EXPO will help attract more businesspeople to the UAE,
which will be encouraging news for the hotel industry. The World Expo 2020 will definitely benefit the region and will attract more tourists. It will boost travel and tourism and will, most importantly, help give the much-needed push to the construction industry.
Previously, you stressed the importance of coordination and communication between the consultant and contractor while working on projects. What are the challenges the lack of coordination poses during the design phase among the architect, the MEP and structural engineers and contractors? And how can they be addressed? Close coordination is essential, as it enables the consultant to create a complete and more efficient design with fewer changes in the future. Poor coordination, on the other hand, leads to an incomplete design and will have a huge financial impact, eventually delaying the completion of the project. It is always advisable to have one consulting firm with all the disciplines – for instance, the architectural and the electro-mechanical department, which can work on the complete design. This will enhance close coordination within the disciplines, which also has a positive impact in completing the design on time. It avoids unnecessary problems through the construction period. In addition, using the latest technology and cost-effective products will have a positive impact on the project.
Could you elaborate on current challenges? How do protracted payment periods, less-favourable contract conditions and the increase in instances of contractrelated disputes impact the construction industry? Long payment periods pose a huge challenge to the entire construction industry. The developers often want long payment periods to accommodate their sale; as a result, the contractor has no choice but to accommodate it. If the contractor has sufficient
financial backup, there will be minimum challenges. This is where local banks play a big role. But if the contractor does not have financial power, the delay is carried to the subcontractors and suppliers; as a result, it becomes cyclical. The initial period of change from normal to long payment terms and its impact will be hugely felt. But when payments are delayed beyond the already-agreed long periods, it poses further challenges. This leads to fault finding. It can also lead to minor quality issues on product or workmanship being held against the contractor or subcontractor as the reason for the delay in payments, which then leads to disputes. Sometimes, issues arising out of inadequate planning in the initial stages of the project, and failure to allocate sufficient time for authority approvals and for obtaining various NOCs also lead to delays and, possibly, disputes. The significant challenges arising out of developers prolonging or delaying the payments are: ■ Undue and sometimes avoidable delays in the original project programme ■ Financial implications, as indicated earlier. If anyone in the chain – the contractors, sub- contractors, suppliers, manufactures and even the consultants, is badly hit, the situation can lead to further delays and disputes. ■ The impact on developers or clients in terms of their not being able to collect their revenue, as planned during the design stage. ■ The possible negative impact on the final product standard and finishes. ■ The impact on cordial relationship among developers, consultants, contractors and their supply chain, many a time leading to some of them deciding not to work together again. ■ The possible negative impact on the accreditation of the contractors, suppliers and manufacturers with regard to their banks, which leads to further strain on their financial standing. ■ Delayed delivery, or substandard product or poor quality of finishing, which affects the reputation of the developer or the client. The consultants must advise their clients about the problems arising out of delayed payments and the resultant delays and consequences. Delay in payments is certainly one of the serious issues faced by the construction industry today, but I believe that consultants and contractors, through properly estimating and understanding cashflow requirements, can go a long way in avoiding unforeseen problems.

pproximately 5,5007,000 air-handling units (AHUs) and 200,000250,000 fan-coil units are sold in the UAE every year. This comes from Faisal Shaikh, General Manager, Clima Uno Air Conditioning. He says that the figures with regard to the sale of the units have been steady over the last 2-3 years. T R Ganesh, General Manager, Blueair, Middle East and Africa, pointing to how AHUs and FCUs come under the scope of air purification, agrees with Shaikh that the overall air treatment industry is growing, not only in the UAE but also in the Middle East region. He puts the value of the air purification industry at USD 80 million in the Middle East. Overall, the air purification market in the Middle East, he says, is likely to experience growth of approximately 17% on a yearon-year basis. “The air purification equipment market in the Middle East is expected to touch USD 100 million by the year 2021,” he adds. There are others who contest the market figures provided, saying there is no structured way of estimating market size. The fact remains, though – the air treatment industry is on a growth trajectory. To maintain this growth, though, industry representatives say, there is a need to focus on specific aspects, such as the air filtration market. Suraj Kumar, Technical Manager, Air Solutions, LG Electronics Gulf, says: “Maintenance of such [air filtration] systems is crucial and necessary for the optimum functioning of equipment and for appropriate energy consumption.” Maintenance and operation of HVAC systems in commercial buildings, he adds, has traditionally been carried while complying with statutory requirements for health and safety. “Due to short-term commercial pressures,” he says, “the lowest tender price submission from maintenance contractors is often accepted, with little consideration given to long-term value for money.” Therefore, Kumar says, the opportunities for achieving energy-efficiency gains and lifecycle costs are subjects that are often neglected. Darren Naicker, Sales Director, Filters Division, Camfil Middle East, also stresses on maintenance as having a key role to play in the smooth operation of an HVAC system, including what Kumar describes as working to lower energy consumption. He says:

“Without timely maintenance, the system will suffer pressure drop, resulting in increased energy consumption and a compromise on IAQ (indoor air quality).” By monitoring the pressure drop, he says, all filters installed in the system will have a reduced energy consumption and an improved IAQ. Shaikh adds that proper maintenance plays a key role in the delivery of clean air. He says: “Condensation tends to happen across the coil, and the drain pan is always expected to be wet and damp, which then also leads to poor IAQ.” Pointing to preventive maintenance as one solution to the problem, Naicker says: “Preventive maintenance must be arranged in order to ensure that the equipment installed functions in accordance to the manufacturer’s operating standards.” Echoing the thought and stressing on the importance of preventive maintenance, Kumar says: “Having a preventive maintenance schedule will give tangible returns and will also add to the life of a system.” Additionally, he says, it lowers
energy and repair bills. Naicker adds that as a rule of thumb, the time spent on an AHU for preventive maintenance must be a minimum of 15 minutes every month. “We see that this is not the case, as most customers consider the time spent cleaning filters as preventive maintenance, which is incorrect,” he says. The best practice, Naicker suggests, is to replace the filter after it reaches its final pressure drop, which will ultimately increase efficiency. Shaikh highlights that within a preventive maintenance programme, ASHRAE standard
THE ISSUE, POST-CONDENSATION
180-2018 can be used for inspection in commercial buildings, while ASHRAE standard 62.1-2016 can be used to check for ventilation and acceptable IAQ. Jatin Sachdeva, General Manager, Au Pure IAQ Solutions, says there are additional aspects to the air treatment market that deserve attention. He says: “What we need is minimum IAQ standards, maintenance protocols and specifications, more costeffective maintenance options and disruptive design solutions.” These, he says, in addition to authorities encouraging a regime that allows for adopting new technologies and design approaches. Staying on a growth trajectory, representatives agree, is not easy. It requires constant intervention that furthers the cause of energy efficiency and IAQ.
he formation of algae and impurities causes the line to get clogged, and results in improper drainage of condensate water, says Suraj Kumar, Technical Manager, Air Solutions, LG Electronics Gulf. The answer to the situation, he says, is the timely cleaning of the filter. Faisal Shaikh, General Manager, Clima Uno Air Conditioning, explaining the science behind condensation, says, “The factors contributing to condensation can be attributed to infiltration caused by the pressure difference inside the air-handling unit.” Condensation, Shaikh says, can also take place due to uneven air temperature, untreated humid air – that is, moisture carryover that bypasses through the coil due to a high velocity across the cooling coil. “Designing and manufacturing units,” he says, “therefore must strictly follow guidelines, as prescribed by the ASHRAE design guides and handbooks, in conjunction with certification bodies like Eurovent or AHRI.” Besides poor maintenance practices and the need for more stringent design and manufacturing practices, nature’s intervention, in the form of high humidity in the region, is a significant challenge. The need to overcome the highly humid conditions in the region has necessitated a change in design parameters. This has resulted in an increase in costs of AHUs and FCUs. The cost of AHUs has especially increased in recent years, Kumar says, adding that there is a silver lining in that the market has been able to witness an improvement in IAQ. High-efficiency, double-wheel FAHUs, he says, are now becoming a standard for most projects.

cRITIcAl SpAcES Precise HVAC control solutions are essential in healthcare facilities, writes Syed Taqi Hussain
n today's healthcare facilities, flexible, customised, stringently controlled spaces serve the needs of patients, healthcare providers, staff and support services. Safety is paramount; cost-effective sustainability is equally so. Dependable precision performance is required to meet all the goals of facilities. Valves and support devices that are consistently accurate reduce energy consumption and lower operating costs. Valves maintain airflow by adjusting to internal changes in static pressure; some valves enable response times under one second.
MONITOR PRESSURE, ALARMS, OCCUPANCY CONTROL The first concern for a facility is maintaining a healthful environment for patients and caregivers. The basic requirements in a healthcare suite are:
Operating Room GZeZViVWaZVXXjgVXn BdgZjei^bZ :cZg\ndei^b^hVi^dc Isolation Room EgZhhjg^hVi^dchV[Zin 8dYZ"Va^\cZY ;aZmheVXZ Patient room :ck^gdcbZciVaXdcigda EVcYZb^Xdei^dch CdgZ\jaVgbV^ciZcVcXZ Room pressurisation is increasingly becoming more critical throughout all hospital spaces, not just isolation rooms and operating rooms. In view of the above, the control platform proposed leverages the improper airflow control made possible by variable
air volume (VAV)s or fan-powered VAVs used in healthcare facilities. Using pressureindependent VAVs in critical areas will provide an unsafe, most ineffective solution for control of temperature, room pressure and humidity. GddbegZhhjg^hVi^dc·CZ\Vi^kZ situation is compromised, as the actuator time for opening and closing the standard pressure-independent VAV is above 90-120 seconds. KZci^aVi^dc^hXdbegdb^hZY!Vhi]Z fan-powered VAV will use the existing flow within the isolation room; this scenario should be completely avoided, as the pressure in the room should be maintained as negative and any mixing of air is completely avoided. Standard VAV box control is based on actuator time for opening and closing within 120 seconds.
▶ Pressure Independent Control Logic for the Damper Actuator
THE SEQUENCE OF OPERATION – TYPICAL FOR CRITICAL AREAS: 1. Room schematics: The following figure shows a schematic diagram of a typical room without CAV.
of the space by measuring the space and/or a duct-mounted temperature sensor(s), comparing it to one or more temperature set-points and regulating cooling, heating and auxiliary temperature control outputs to maintain a consistent space
from cooling/heating minimum flow setting to cooling maximum flow setting. Negative or Positive zone pressurisation is maintained by controlling the exhaust valve to a flow equal to the supply valve’s feedback plus the design offset entering the space
[Exhaust Flow = Supply Flow + (Offset)]
A drop in temperature to the room set-point causes the supply and exhaust valves to decrease flow until their minimum positions are reached, as listed on the room schedule sheet. On a further drop in zone temperature, the valve will modulate the electric duct heater to maintain the set-point.
▶ Typical room without CAV
2. Zone Pressurisation Control: As the static pressure in the exhaust and supply duct systems fluctuate, the pressure independent cone/spring assembly of each valve shall modulate to maintain a fixed set point flow within one second. The Zone Balance Control function is responsible for summing the feedback of all the supply and exhaust valves, factoring in the desired offset value and commanding the valves under control to flow set points that satisfy the simplified equation:
Beyond the desired ventilation rates and offset, Zone Balance Control may also be influenced by thermal override and occupancy status in order to keep the space comfortable and in “balance”. Emergency modes override zone balance to drive the valves to predetermined positions. The supply valve flow command shall be generated by comparing the minimum ventilation demand, the makeup air for hood demand and the thermal demand signals, and selecting the highest of these three settings. Negative zone pressurisation is maintained by controlling the exhaust valve. The general exhaust valve shall open when additional exhaust flow is required to maintain zone pressurisation.
temperature. There are four temperature control loops, which are designated as: Eg^bVgnXdda^c\WnlVnd[i]ZgbVa override of conditioned air with supply and exhaust maintaining desired offset Eg^bVgnXdda^c\WnlVnd[Xdcigda of cooling device using analogue output Eg^bVgn]ZVi^c\WnlVnd[Xdcigdad[ a reheat coil using analogue output or floating point triac output 6jm^a^Vgnadde[dgZ^i]ZghjeeaZbZciVa heating or cooling by way of either an analogue or digital output >[bdgZi]VcdcZiZbeZgVijgZhZchdg input is used, a straight-line average of all inputs is used as the Effective Temperature set-point, which serves as the basis for all temperature control functions. :VX]eg^bVgniZbeZgVijgZXdcigda loop operates independently, and has its own set-points and PID control parameters. The Auxiliary Temperature Control set-point may be configured as either an absolute value or an offset value relative to the appropriate temperature set-point (cooling or heating). Auxiliary temperature control may be configured for either modulating or two-state control, as well as standalone or staged operation.
3. Temperature Control: The lab, operation theatre, isolation room controls system will control the temperature
A rise in temperature above the room set-point flow causes the supply valve to increase the airflow into the room linearly
[Total Supply] = [Total Exhaust] – [Offset]
4. Occupancy Control: Occupancy control consists of changing the minimum ventilation rate and temperature set-points based on commanded occupancy state. There are three occupancy modes (Occupied, Unoccupied and Standby) plus an override state (Bypass). If an occupancy schedule is desired, it must reside in the BMS system. Lets look at the four modes... Occupied mode: Ventilation rates are set to maintain a safe environment, assuming normal working conditions and users are present, and there is optimum temperature control for occupant comfort. Unoccupied mode: Ventilation rates may be reduced considerably, assuming that no work that would generate undesirable fumes or vapours is being conducted and no users are present. Temperature control setpoints may also be relaxed, as comfort in an unoccupied space is not critical; indeed, allowing a greater dead band between cooling and heating set-points will reduce energy consumption. Standby mode: Allows the setting of cooling and heating set-points for a state between the occupied and unoccupied setpoints. Ventilation rates are the same as the occupied mode. Temperature control set-points are the same as the occupied mode but with a separate programmable dead band to change effective cooling and heating set-points. An example might be a space that is out of service or has been decommissioned.
Bypass mode: A means of locally overriding an unoccupied command to set the space to the occupied mode for a predetermined time period (also known as bypass time). In the occupied mode, the ventilation rate should be calculated to provide the air changes necessary to maintain a safe environment under worstcase conditions. Cooling and heating commands will be driven to maintain the space temperature to within ±1 degree C of the desired set-point. In the unoccupied mode, the ventilation rates may be reduced. Also, since comfort of a space with no inhabitants is less critical, the temperature control parameters may be “set back” to a lower set point and/ or a wider cooling/heating dead band, thereby reducing energy consumption. In the bypass mode, a local occupancy override button will allow users to override the occupancy mode and set the space to occupied mode for a predetermined interval.
5. Emergency Mode Control: Emergency mode control consists of valve-level and zone-level control functions that allow the flow rate of any or all valves in the space to be overridden to a predetermined percent of flow, or shutoff set-points. There are four Emergency mode states and 1 Pandemic mode that are independently configurable. Thermal override for temperature control is inhibited, while an Emergency Mode is active. The airflow control system will provide a means of overriding temperature and pressurisation control in response to a command indicating an emergency condition exists, and airflow control devices are to be driven to a specific flow set point. The system will support up to nine emergency control modes. They are prioritised from 1 as the highest to 9 as the lowest. The emergency control modes may be initiated either by a local contact input (E Modes 1-4) or BMS command.
Once an emergency mode is initiated, the valve(s) will move to their pre-programmed set point until the input that triggered the emergency mode returns to its normal state. The local contact input takes priority over the BAS command. Each node may have up to nine emergency mode set-points configured. Each node may be configured separately. Emergency modes are initiated based on the nodes defining a pressurisation zone. Therefore, if Emergency Mode 1 is activated, only those devices that have an Emergency Mode 1 set-point in that specific zone respond to the command. Once initiated, the emergency mode is “locked” and can only be reset, or returned to a normal state, by the device that initiated the command. All emergency modes must be cleared before the system will revert to normal operation.

adding that load centres in Baghdad, Basra and Mosul were built almost 50 years ago. As such, he says, the distribution network was not designed to meet the requirements of the current number of residents and the load of modern necessities such as air conditioning, all of which must be taken into consideration to reduce the financial loss from such inefficiencies. Placing the current capacity in the country at 16,000 MW – 18,000 MW, Istepanian points out that demand for power is only set to increase 8-10% annually, in view of the GDP and population growth. He emphasises that the requirement for reliable power must be addressed, since Iraq, similar to its
Road to Re A new, enthusiastic and dynamic Iraq is emerging from years of conflict and uncertainty, yet challenges lie ahead, as the quality and number of existing infrastructure is unable to meet the current needs of its citizens and the requirements of a government working towards economic self-sufficiency. Hannah Jo Uy of Climate Control Middle East takes a closer look at the nation’s road to rehabilitation…
esopotamia was once home to a myriad different cultures and civilisations, with a rich history dating back thousands of years. Now known as Iraq, the fabled land between the two great rivers, the Tigris and the Euphrates, is more concerned with its future rather than its past. For more than a decade, the country was the battleground of wars that have left the once prosperous nation devastated. Today, Iraq and its people are eager to write a better story for the next generation. The years of fighting scarred the land, as revealed by the destruction of infrastructure, the deterioration of whatever remained, and the insufficient number of facilities, all unable to meet the basic requirements of the population. Harry Istepanian, Senior Fellow, Iraq Energy Institute and an independent power consultant based in Washington D.C., USA, puts the number of Internally Displaced People (IDPs) in Iraq at between two million
and 2.5 million – a conservative estimate, he neighbours in the Middle East, is subject says, as the figure may be higher.

we will get there again in a couple of years, as long as governments and companies keep improving the relationships,” he says. As Timothy McLaren, Senior Commercial Contracts Engineer, Ramboll, puts it: “Iraq is open for business for anyone that has a preference for them." Dr Tarik Al-Omran, Professor, Material Sciences, Baghdad University, echoes this saying that as the country makes a move to enhance its nonoil sector, manufacturers from all over the world have an opportunity to take part in the country’s rehabilitation, which is encouraged by the government through a number of incentives.
The energy crisis is only the tip of the iceberg, with Mills emphasising that the government also has a pressing need to develop infrastructure related to the water sector. Moustafa Hassan, General Manager (Iraq and Jordan), Metito, echoes this, pointing out that there has been an increase in demonstrations in Basra, as thousands were hospitalised from bad quality water. Currently, Hassan says, the Total Dissolved Solids (TDS) in the water in Basra range from 25,000 to 30,000 PPM. According to the World Health Organisation (WHO), the acceptable range of TDS is only 1,000 PPM. This, Hassan stresses, is a relaxed version,
been a steady increase in the sale of inverter splits in Iraq – with market share increasing year on year from one per cent in 2014 to almost 10% in 2018. “While the retail market currently accounts for 90% of our business,” he says, “we are anticipating that will shift and our light commercial segment will gain popularity as the new commercial projects in the country get realised.” Al Ghussein says there is big opportunity for VRF technology in villa and hotel developments, adding that the company is looking to contribute energyefficient cooling solutions to the country’s retail, hospitality, leisure and residential sectors.
as more conservative implementation of WHO standards even require TDS below 500 PPM. Hassan says the company, which has a long history in Iraq, is proposing long-term solutions to address TDS and make tap water acceptable for drinking and irrigation, to government entities. Previous projects, Hassan says, were put on hold, as funds were diverted for military spending, but that Metito resumed work in three out of the seven ongoing projects and expects work to resume for the remaining four in Baghdad soon.
The construction sector has attracted new names, as well. Arda A SOURCE FOR FUNDING Haçaduryan, Deputy Manager – Director While interest in entering the Iraq market After Sales Service, Metrology Group, says is palpable, much of the momentum is that the company’s interest restrained by questions in Iraq grew following its surrounding the reliability of cooperation with Reftrade, the funding for projects in a company that represents the pipeline.

However, this will take time. “It’s not something you will see by end of the year,” he says. “It may take 5-10 years.” While Iraq looks to foreign investment to stimulate the construction sector, Istepenian points out that ith a population approaching 40 million, Iraq has a unique advantage currently, owing to the low oil over its counterparts in the GCC region, says Robin Mills, CEO, Qamar prices, the country has a deficit of Energy, and Senior Fellow, Iraq Energy Institute, emphasising that this USD 22 billion dollars [based on means the country will not be reliant on expatriates for its workforce.

Harry Istepanian, Senior the government is expecting the Fellow, Iraq Energy Institute, and an independent power consultant based in Washington D.C., private sector will participate in USA, puts the unemployment number between 20 and 30%. addressing the deficit. However, Istepanian stresses that the massive gap in unemployment can be addressed through greater Mills believes that the current support for the construction sector, which is highly labour-intensive and creates a requirement for market is not as “private-sector friendly” as one would hope for, builders, electricians, plumbers and engineers.

adds that policies would be effective so long as they balance cost and promote technically acceptable standards that do not compromise on safety and quality, while allowing companies to remain competitive. Pointing to another issue plaguing the market, Hassan says local stakeholders do not have the necessary expertise to properly evaluate technical specifications of tenders. Decision makers, Hassan says, often opt for the cheaper option, despite it not being the best solution, for fear of being questioned on why a project was awarded to a higher bidder, as they are unable to explain the long-term technical, financial and operational benefits of one solution over another. As distributors of European brands, Haçaduryan says this serves as a challenge for the company “as convincing for the best quality is never as easy as it seems to be”. Dr Al-Omran echoes the importance of directing investment towards high-quality products, saying that the market has long suffered from installation of bad quality equipment in the previous years. For many stakeholders education is the best antidote to safeguard the industry from skewed, cost-centric thinking. Istepanian supports the value of training, saying that many local stakeholders are not proficient in contract management, owing to lack of experience, leading to mismanagement of projects and existing resources. Hassan believes this can be addressed through the exchange of knowledge, and that it is important to have international consultants enter the country to share knowledge and to conduct trainings. He adds that there is a need for assessment of technical qualifications before proposals are submitted, so the consultant is liable and responsible for decisions. This creates an ecosystem that will make it easy for the Iraqi government to procure good-quality and long-lasting products and equipment at competitive prices. Al Ghussein says, “While the challenges of the Iraq market are huge, so are the opportunities.” Indeed, as Iraq and its people usher in a new era for the country, the international community, particularly those in the GCC region, could play a vital role in helping the country move forward and, most importantly, do so in the right fashion.

THAT SQUEAKY, SQUEALING, NOISY THING AGAIN!
Gerald Stewart, Principal Acoustics – Inhabit Group, adopting an introspective tone and through posing questions to himself, shares his insights on the need for acoustic certification with Climate Control Middle East…
veryone has a five-year plan, right? Acoustics and the Middle East region should not be any different, so is it time for a rethink, or are we doing okay?
From the outset, one of the most noticeable things I have seen is the change in attitude amongst architects, developers and builders alike, regarding acoustics. They all want it included in the design stages, now that it is included in many federal decrees with the various building regulation minimum and ‘Green’ requirements, but at the same time, I still see the VE axe cutting a fair swathe through our good intentions, at the cost-planning stage or slightly after – that is when the tenders come back in.
So, why is this still the problem? Years ago – to be specific, in a 2013 article in Climate Control Middle East – I had mentioned that controls weren’t in place to ensure compliance with regulations and, despite writing these criteria into design and specification documents, the actual times I’ve been asked to go in and measure a completed building for acoustic compliance here in the Middle East is countable on my
fingers (and I would have a few left over to hold my morning coffee!). The number of designs the Middle East region’s other acoustic consultants and I have provided far outweighs the signed confirmations of meeting the required compliance standards, at building handover.
I ask again, ‘So, why is this still the problem?’ Again, there really isn’t a one-size-fits-all response to this question, but I suspect it comes down to ‘it isn’t actually law, so why should we’. This is not the correct answer, as in the United Arab Emirates the federal decree by the implication of the various named standards does ‘make it law’, as the standards state that a building or portion of it must be tested on completion. So, why does this not occur? I believe it comes down to one or two major reasons – cost and continuation. The cost is that a builder would need to procure the services of a third-party acoustic consultant, and this brings in the second reason, which is that in many projects the acoustic consultants probably aren’t going to want to give away work to someone else. This attitude is being driven by acoustic consultants, because we are all protective of our patch, and this giving away of work doesn’t gel well with the effort we must go through to win a client, work on the project and see it all to fruition, only to be ‘marked and assessed by someone else’. To this, I say: “Hold on! What if you have to go and mark and assess another consultant’s building and so on and so on? Aren’t the acoustics of the world going to get better? Isn’t this why we’re all here? To do good for the world? This is certainly the underlying desire of my office.” So, dare I say that some simply need to let go a little bit to gain a lot, and the world benefits, too. Everyone loves ‘win-win’, but everyone loves ‘win, win, win’ even more, don’t they? Well, it seems not. I can’t believe that I am the first person putting it out there, so maybe it isn’t the reason, after all? Let us explore the natural alternative. Let us all forget about acoustics and not worry about it at all forever more. I can hear right now the thundering feet of 10,000 acoustic consultants beating down my door, to tar and feather me, but the sharp reality is that few people really understand what it implies, even fewer know how to spell the word, and even fewer among the fewer still want to pay for any of it, because they can’t see it. The norm seems to be: ‘Let us forget it and cut the standards out. Let us make everything as cheaply and as quickly as possible, with the materials we are used to using and have readily available.’ Indeed, almost everyone seems to be saying, ‘Let’s not try to make it better, let’s just build it, until we move into our new AED 5 million apartment, that is, and all we can hear is the noise from our neighbours, and our children can’t study, because they can’t hear themselves think.’ I was standing in an apartment recently, near a new high-end part of town, and a nightclub was booming along happily quite a long distance away, and with the windows and doors of the apartment closed all I could hear (and almost feel) was the noise of the music. The time was around 8pm, well
before that particular nightclub really gets going! Forget about buying a TV for this one, I thought, it would be a waste of money. But then I dug deeper and graciously excused myself and told the seller that with that noise in the background, buying this apartment would be a waste of my money. I like the sound of the music of my choice, at my time, and not the sound of a nightclub going crazy, well into my sleep time. On discussion, the seller said he had been trying to sell since a month after buying, because the noise had ruined his life for the last six months. He bought off-plan and didn’t realise what he’d gotten himself into. He was not able to upgrade the façade or make any changes to his apartment to block the noise. I felt sorry for him but not enough to want to buy his apartment. As nice as the view was and as wonderful as I could imagine it to be living there without the noise, it was a definite no-go zone for me. Money, it appears, is the realm of those rich enough to have it and the rest of us need to accept what they want us to have, which is why I suspect these new apartments, built under the current law, if measured, would fail to meet the standards. So again, I come back to measurements for compliance – why bother, and yes, I can still hear the thundering feet of 10,000 acoustic consultants, but the reality is that sustainable design, and new and practical ways to build buildings bring us to this level. “Cut out what you can’t see and delete everything unnecessary, no one cares.” I did hear a developer make this very statement and was pretty much in agreement with his last words, “no one cares”.
I still believe this all comes down to the one simple missing link – we don’t have municipality people in place to support the sign-off process. We have Civil Defence and an army of municipality engineers to sign-off all other parts of a building, but we perhaps also need to have the right people with the right qualifications in the right positions to administer and sign-off the various noisecontrol objectives. This is clearly a big ask for any government to implement quickly, as there are very few available and highly trained acoustic practitioners for the consulting market, let alone to have Arab nationals in each region to facilitate the acoustic sign-off process, but we do have the means to solve this problem. I take it right back to the start, where we have plenty of suitably qualified and registered acoustic consultants and enough work to go around that a third-party assessment process could easily be invoked and mandated with a paper-trail process put in place in municipality departments, to make sure that people can live in peace and harmony and that the night clubber in all of us can still go somewhere to enjoy music that is far too loud for comfort and can then come home at any time – day or night – and not be woken up by someone next door dropping a pin on the floor of their apartment.
If we all had this attitude, where would we be. Probably ‘existing’ in an unsafe building with no services, no safety, no security, no fire control, no roof, no windows, no doors… hmm… isn’t that a cave? So, why is it that we have fire codes and sign-off, we have electrical codes and sign-off, we have mechanical codes and sign-off, we have sustainability codes and sign-off and we have architectural codes and sign-off. Why do we still not have sign-off for the acoustic codes we already have in place? We have cinema builders in Saudi Arabia making sure that their designs comply by ensuring there are qualified acoustic consultants going in to measure both during and on completion, and tests to ensure they meet codes. In 2016, 18-24 year-olds went to the movies an average of 6.5 times over the year, up 0.6 from 2015. This was the largest increase of any age group. Per capita attendance was next highest for 12-17 year-olds (6.1). Per capita attendance also increased for 25-39 year-olds and 50-59 year olds compared to the previous year. Per capita attendance increased for African Americans and Asians/Other Ethnicities compared to 2015. In 2016, Asians/Other Ethnicities reported the highest annual attendance per capita, going to the cinema an average of 6.1 times in the year. (source MPAA-Theatrical-Market-Statistics-2016) We spend a “frequent average” of 12 hours per year/per 11% of humans in a cinema, and these are tested not once, but often twice, for compliance, yet every one of us spends 2,920 hours at home per year trying to sleep, and we still have no acoustic compliance-testing in many regions. We even have a higher rate of testing for offices than we do for residential apartments and co-joined residences, so where exactly are we missing the point?
The choice, of course, is a cave; there are a few of those still available, but I’ve heard they can get a little uncomfortable and damp at times, though if you go far enough inside, you may get rid of most noise. The approaches repeated – note these options were presented in the original text from five years ago and, surprisingly, we have the laws in place now, but they are still not being checked for compliance at the end of a project – that is, in the handover stage.
PRESCRIPTIVE APPROACH – DEEMED-TO-SATISFY SYSTEMS This option uses only systems that comply with Deemed-to-Satisfy Provisions. These building elements would be constructed and installed as outlined in the regulations. The construction of the building elements should be inspected, and evidence documented that the building elements are in accordance with the provisions of the regulations. The evidence can be in the form of a summary of building materials used on site, regular memorandum of inspections, overall list of defects, construction photographs of key elements and a summary of the rectification measures undertaken on the project. Acoustic certification for occupancy is issued when all defects have been rectified to the satisfaction of the acoustical consultant.
PRESCRIPTIVE APPROACH – LABORATORYTESTED SYSTEMS These building elements would be constructed and installed as those systems tested in the laboratory. The construction of these building elements would be inspected, and evidence documented that the building elements are in accordance with the tested systems. The evidence can be in the form of a summary of building materials used on site, regular memorandum of inspections, overall list of defects, construction photographs of key elements and a summary of the rectification measures undertaken on the project. This option uses only systems, which have been verified by testing in an approved testing laboratory.
PERFORMANCE APPROACH – VERIFICATION METHODS – FIELD TESTING The building elements would be constructed as recommended, including any additional detailing to limit flanking noise. Inspections would be conducted, defects rectified, and documentation produced, which demonstrates compliance with the construction requirements. Testing is then conducted on a suitable number of building elements. Typically, at least 10% of all wall systems should be tested. For some complicated sites, this may be 40–50%. The documentation can be in the form of a summary of building materials used on site, regular memorandum of inspections, overall list of defects, construction photographs of key elements, a summary of the rectification measures undertaken on the project and a copy of the results of acoustical testing.
For this option, it is expected that only systems that are likely to comply, when tested on site, would be used.
PERFORMANCE APPROACH — CHECKING FOR COMPLIANCE — EXPERT JUDGEMENT This option uses only systems, which in the opinion of an expert acoustical consultant, would meet the required performance scheduled in typical standards. The ability of a consultant to make an expert judgement needs to be documented, as does the basis of their opinion. Typically, testing would need to have been conducted on the proposed system. The consultant would, then, need to form an opinion that the proposed system complies with the provisions of the regulations. The building elements would be constructed as required. Inspections would be conducted, defects rectified and documentation produced, which demonstrates compliance with the construction requirements.
PERFORMANCE APPROACH — COMPARISON WITH DEEMED-TO-SATISFY SYSTEMS This option uses only systems which, in the opinion of an expert, would match the performance of Deemed-to-Satisfy Systems. The ability of an expert to make an expert judgement needs to be documented, as does the basis of his/her opinion. Typically, testing would need to have been conducted on a proposed system, and an expert would have formed an opinion that the proposed system is no worse than a Deemed-to-Satisfy System based on these test results. The building elements would be constructed as required, inspections would be conducted, defects rectified, and documentation produced, which demonstrates compliance with the construction requirements. The intent of this approach is to consider treatments for services relating to noise insulation and for impact rating of walls. An example is to measure the noise intrusion level from waste pipes adjoining the room and comparing these levels with the equivalent level from a Deemed-to-Satisfy System. The impact rating of walls is a more difficult undertaking, as no test method is universally acceptable to all interested persons.
EmpowEr rEnEws commitmEnt to cut cooling Emissions “As a key partner of UN Environment’s ‘District Energy in Cities Initiative’, we are dedicated to reduce harmful emissions generated by heating and cooling systems,” says CEO of the utility company By CCME Content Team
ubai-headquartered Emirates Central Cooling Systems Corporation (Empower), is reaffirming its commitment to cut cooling emissions in response to the fresh strides made by UN Environment, the District Cooling utility said through a Press communiqué. In a recent statement, Ahmad Bin Shafar the global environmental authority has announced new developments in the efforts to curtail cooling and heating emissions worldwide. The very latest is that the UN Environment plans to support new District Cooling projects in India and in Bosnia and Herzegovina as part of its ‘District Energy in Cities Initiative’. Over the last few years, UN Environment has cautioned that the expansion of middle class in developing economies will place heavy demands on heating and cooling systems worldwide – particularly as temperatures across the planet climb to unprecedented, dangerous highs – and will result in ballooning the greenhouse gas emissions. According to the organisation, traditional cooling systems consume over 50% of building energy, as well as run on the excessive use of fossil fuels that further exacerbates global warming. District cooling has been selected by UN Environment as an unparalleled energy-efficient and energy-saving solution. Empower said through the communiqué that in line with UN Environment directives, it is committed to decreasing emissions by cultivating a culture of efficient District Cooling systems across the UAE and beyond. By partnering with UN Environment’s ‘District Energy in Cities Initiative’ – an initiative targeted at delivering significant environmental benefits around the world – Empower has scaled up its
efforts to a larger and global level, the utility company said through the communiqué. “As a key partner of UN Environment’s “District Energy in Cities” Initiative, we are dedicated to reduce harmful emissions generated by heating and cooling systems,” Ahmad Bin Shafar, the CEO of Empower, said through the communiqué. “We are committed to implementing our strategy to reduce the harmful emissions from cooling systems by working and joining forces with our strategic partners, including UN Environment.” Bin Shafar stressed that Empower highlights the importance of promoting environmentally sound practices and sustainable developments across the UAE, as well the rest of the world. Empower, the communiqué said, also provides financial aid to conduct a study to evaluate the potential of District Energy Systems in certain parts of India. Meanwhile, here in the UAE, Empower is actively contributing to the implementation of the UAE Energy Strategy 2050 and the Dubai Clean Energy Strategy. Empower became a partner of UN Environment in the District Energy in Cities Initiative as a multi-stakeholder to extend its efforts beyond the UAE. Coordinated by UN Environment, the initiative is supporting efforts to shift the heating and cooling sector onto energy-efficient and renewable energy solutions, the communiqué said. It aims to double the rate of energy efficiency improvements for heating and cooling in buildings by 2030 and helping countries to meet their climate and sustainable development targets, the communiqué added. The initiative also supports local and national governments to build expertise and implement policies geared to accelerate investment in modern, low-carbon and climate-resilient District Energy systems. UN Environment is currently providing technical support to cities in eight countries including Bosnia and Herzegovina, Chile, China, India, Malaysia, Morocco, Russia and Serbia.

Mohammed Essa Bundakji, Group Managing Director, Initial Saudi Group, an exhibitor and platinum sponsor of the event, commended MEFMA’s efforts to drive FM standards and initiatives with learning institutes in the region, and highlighted the growing number of projects in the country, which is still the largest consumer market. “MEFMA is attracting more and more Saudi
engagement, because the FM industry in Saudi is growing,” he said. Al Suwaidi echoed this saying it is important to enhance quality of FM providers in view of the strong project pipeline in the region, highlighting projects from Saudi Arabia’s Ministry of Interior worth up to SAR 40 billion, all of which will require asset management professionals, and those relating to new developments in Egypt, which is emerging as a strong FM market. “The construction boom in the whole region in the last 15 years is phenomenal,” he said, “This is where we feel that it is really a sector that will grow – it will never disappear, because you have services you have to provide to buildings of different sectors, like retail, hospitality, commercial, residential and educational. You have a huge sector that needs FM professionals to have the right strategy to manage their buildings.”

ASHRAE Falcon Chapter translates Standard 55-2017 into Arabic The translation of the Standard will help further raise awareness on indoor thermal comfort, an aspect that is not being addressed sufficiently right from the design stage of a building in the GCC region, ASHRAE says By Ranjana Konatt | Features Writer
team from ASHRAE, led by Dr Ahmed Ala’a Eldin Mohamed, Director and Regional Chair, Region At Large (RAL), Board of Directors, ASHRAE, recently translated the ASHRAE Standard 55-2017, on Thermal Environmental Conditions, to Arabic. Elaborating on the reason for translating the standard, Osama Khayata, Translator and General Coordinator, ASHRAE member, Dr Ahmed Ala’a Eldin said: “Indoor thermal comfort, especially in hot and humid Mohamed zones, such as the GCC region, is an issue that is not being addressed sufficiently right from the design stage of a building.” Elaborating, he said, that after having translated Standard 62.1 to Arabic, the team decided that it was time to work on ASHRAE Standard 55 and bring its content to Arabic speakers. “The translation of Standard 55,” he said, “will help raise awareness of its requirements, especially since the Standard has been partially implemented by government bodies such as the Dubai Municipality.” Pointing to another aspect, Mohammad Al Hemide, Translator, ASHRAE member, said: “Standard 55 specifies the acceptable conditions for thermal environments, and its use can be found in design, operation and commissioning of buildings, in addition to other occupied spaces.” Adding, he said, that the Standard addresses six factors to achieving thermal comfort – the metabolic rate, clothing insulation, air temperature, radiant temperature, air speed and humidity. Highlighting how the majority of issues related to thermal discomfort arise, he said that appropriate air temperature, humidity and air speed have a vital role to play, and the Standard will help design engineers understand thermal comfort conditions better. However, Standard 55 has been re-written since the year 2013. Highlighting the changes brought to it, Khayata said, “The requirements of the 2017 edition of the ASHRAE Standard 55 have been simplified and clarify the three comfort calculation approaches in Section 5.3.3 ‘Elevated Air Speed’.” The 2017 edition, he added, includes new requirements needed to calculate the change in thermal comfort from direct solar radiation. Elaborating on how achieving thermal satisfaction within an indoor space is essential for good IAQ, Mohammed Khalil Haleemeh, Translator, ASHRAE member, said: “Thermal satisfaction is one of the challenges that the HVAC designer faces during the design process.” However, he added, thermal satisfaction depends on many factors, two of them are the metabolic rate and clothing insulation. “These factors vary,” he said, “depending on a person’s activity and the clothes he wears.” Elaborating, he said, that means in some cases, it is not possible to find one set of conditions suitable for everyone at the same time.

brandagnostic approach best in an epc-driven market, says enova We work with leading manufacturers and engineers and offer custombuilt solutions, says company’s representative By Ranjana Konatt | Features Writer
The company said it has added key projects to its portfolio and that it has acquired a cooling plant and pipeline network in Al Barari, established by the project’s main developer, in 2018. Empower has initiated its work for major projects, including Deira Waterfront, Al Barari Development and the designing of a 40,000 tonnes of refrigeration (TR) District Cooling plant for Dubailand Residence Complex. It also has contracts worth AED 250 million to expand its pipeline network in some of its projects, like Sheikh Zayed Road, to transfer District Cooling services from its plant located in Business Bay to serve Dubai Arena as well as some towers. Said Ahmad Bin Shafar, CEO, Empower: “The network of District Cooling transmission pipelines is steadily growing from year to year, reflecting the increase in number of projects Empower is implementing and its proven approach to develop its infrastructure further. The growth highlights the confidence of investors and developers in District Cooling systems and in its role as an environmentally friendly solution due to the high efficiency, and reduced operating and maintenance cost, while improving Empower’s overall competitiveness.” Bin Shafar noted that the innovative solutions and technologies that Empower is developing, particularly in the pipeline network, are part of its efforts to implement the UAE Green Growth Strategy, launched by His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai. The initiative is divided into six main tracks, and
Ahmad Bin Shafar
aims to make the UAE a global hub and a successful model of the new green economy, and support global efforts to reduce carbon emissions. District Cooling, he said, is one of the energy efficiency accelerators, as announced by the United Nations. Empower, he said, has succeeded in creating smart solutions for the challenges it faced due to the special technologies that it uses for equipment and pipes to pass without causing any road damage, or disrupting traffic flow. Empower, he said, is keen on using innovative technologies to control the water flow, through faucets and special equipment, to complete the process of switching cooling systems without interrupting the service. Empower's new pipeline technologies, Bin Shafar said, contribute to reducing carbon emissions and reducing water and energy consumption by providing efficient and environmentally friendly District Cooling services that allow the company to maintain cooling, without being affected by external factors and high temperatures, especially in summer.
n Energy Performance Contracting (EPC), each market is different, and in order to enable a certain level of flexibility, we follow an approach that is brand-agnostic, said Francisco Ramalheira, Director, Business Development and Marketing, Enova. In an EPC market, he said, the ESCO guarantees the level of savings, which translates into the economic Francisco Ramalheira aspect of things. Elaborating, he said: “We work with leading manufacturers, engineers and offer custombuilt, in-house solutions and also consider requirements based on the local market.” Pointing to the importance of having quality equipment in projects, Ramalheira said: “The first thing is that Enova offers a different range of solutions, which are customised to the client’s requirement.” Often, what tends to happen as a result of functioning in an evolving market, he said, is that there will be service companies with less experience. As a result, he added, a sort of natural selection of equipment takes place. “We recommend to look at all the elements for the selection of the most suitable provider, instead of taking a price-driven decision,” he said. With regard to Enova’s experience with the EPC market in the MENA region, he said, we have never had any dispute over performance obligations and are committed to delivering our guarantees as per the contract agreement.
BASF moves regional headquarters to JAFZA One New office will foster collaboration and creativity and will also help us serve our customers better, says VP, BASF By Ranjana Konatt | Features Writer
Dr Udo Huenger
ASF has moved its regional headquarters to a new office in Jafza One, said Dr Udo Huenger, Vice President, Middle East, BASF, while giving an update on the company. “The new space,” he said, “is designed to foster collaboration and creativity, and I am sure that it will allow us to serve our customers in the region better.” In addition, Huenger said that BASF recently broke new ground by producing materials using recycled plastic feedstock. Mechanical recycling, he said, is limited because of an increase of residues in the material in each cycle. “A team at BASF has developed the ChemCycling project,” he said. With chemical recycling, Heunger added, fossil resources for chemical production can be replaced with recycled material from plastic waste. “At our largest manufacturing site at our headquarters in Germany,” he said, “we are already developing pilot products with 10 customers from various industries.” This, he added, includes refrigerator elements and insulation boards.

italy pavilion for expo 2020 aims to tackle global sustainability challenges, says ambassador Architect associated with the design of pavilion provides special preview during keynote address at AUD By Hannah Jo Uy | Assistant Editor
he Italian tradition is a mix between beauty and function, said His Excellency Liborio Stellino, Ambassador of Italy to the UAE, following a special preview of the Italian Pavilion for EXPO 2020, presented by Carlo Ratti, Professor, Massachusetts Institute of Technology; Founding Partner, Carlo Ratti Associati, and one of the architects that designed the Pavilion during Italian Design Day on March 19, at the American University in Dubai. Stellino stressed that legacy is an important element driving Italy’s participation in EXPO 2020 and that the Pavilion aims to showcase key learnings related to food safety and security and future energy gained from previous Expos in a bid to address the global challenge facing sustainability in a more holistic manner. Providing a brief history on the country’s long-standing commitment towards sustainable practices, Stellino said: “The importance of energy started in 1973, when we had the first oil crisis. From the time we tackled problems of energy efficiency, we developed a lot of techniques, technologies and expertise. Today, in Italy, despite the lack of oil and natural resources, we save 20% [of electricity], thanks to better efficiency of buildings.”

Stellino said that despite being associated with classic and traditional buildings, Italy has made great strides in integration of technology for modern infrastructure, owing to the expertise of the engineering and architectural community, stressing that innovation is in their DNA. “The close link between entrepreneurship and art has oriented our design in a more functional way,” Stellino said. Ratti discussed the vital role sustainable cooling plays in modern infrastructure, adding that while the Italian pavilion will be generally cooled using air conditioning, there is a move to incorporate passive cooling design elements to make the most of the time of the year, when the UAE has cooler temperatures.
stakeholders must battle cost-centric thinking in cold chain, says tssc Company official outlines challenges facing the sector; highlights importance of regulation, training to ensure best practices By Hannah Jo Uy | Assistant Editor
he UAE, largely considered a hub for the GCC region, is well-positioned to take a leadership role with regard Miro Donabedian to food safety practices, provided stakeholders address cost-centric thinking plaguing the cold chain sector, said Miro Donabedian, General Manager, Technical Supplies and Services Company (TSSC). “When you want to make things better, hygienic and more energy efficient, there is cost associated to it,” he said. “A lot of times, unfortunately, people are abstaining from putting those options in a bid. They want to bid, and the energy efficiency part is overlooked, because people want to have the lowest cost.” Donabedian added that efforts to enhance energy efficiency only come afterward during retrofits, by changing motors and refrigerants, and only when certain customers specify. Donabedian said that commercial pressures also created greater demand for leasing of transport refrigeration vehicles, as stakeholders are less willing to invest and buy
their own trucks. He said that in such cases, quality of the trucks would be dependent on the end-user, who would specify features to the leasing companies, who are forced to comply. This, he said, can be a problem as not all customers have the same view of investing in proper specifications to ensure the quality of the cold chain. “Also, the way you care for the truck is not the same as when you own the truck,” he said, especially with regard to loading practices impacting the floor, adding that there is more repair and damage on leased trucks that are often abused and used for 24 hours a day. Another niggling problem, Donabedian said, is the lack of skilled personnel in the market to facilitate installation of the boxes, which may lead to inefficient performance and, potentially, leakages. There is a similar need for skilled personnel to ensure proper commissioning and maintenance, as well, he said. For Donabedian, regulation, training and technology play a vital role in addressing these prevailing issues in the market. Providing recommendations on the type of regulation needed, Donabedian said that the government should ensure that boxes and trucks are tested in qualified testing centres before being allowed on the road to

ensure some sort of minimum standards. This, he pointed out, can be an annual exercise to ensure the quality of the trucks. Such a mechanism, Donabedian said, will also safeguard the market from imported trucks coming from countries, such as those in Europe, which are not designed for ambient conditions of the UAE. “Even the cooling units are probably not for these temperatures,” he said. “I suspect the box construction and cooling unit are rated for the conditions there, and there is a risk in running them in the UAE and the GCC region. There should be a test to expose the trucks to ambient conditions and to make sure they are able to do what they are supposed to.” With regard to the lack of skilled personnel in the market, Donabedian said that he believes manufacturers and even distributors of cooling units should initiate proper training for relevant stakeholders and conduct refresher courses through workshops to update the knowledge of technicians involved in installing, commissioning and maintaining the units. Speaking on monitoring, Donabedian said that the growing trend of using telematics will pave the way for a leaner cold chain and that “smart trucks” are the way of the future.
audi Arabia’s entertainment industry is going to play an important role in upcoming HVACR projects, said Faizal Babu Pallathody, Managing Director, VTS Clima. Pallathody said there are especially strong growth opportunities in cinemas, given that Vox Cinemas will invest SAR 2 billion, approximately USD 533 million, to open 600 theatres in the next five years, starting with Riyadh Park Mall. Faizal Babu Pallathody Pallathody added that construction companies expect Dubai-based developer Majid al-Futtaim to tender the estimated USD 1.5-2 billion contract to build the Mall of Saudi development by the end of October. “The retail centre in Riyadh will be one of the largest in Saudi Arabia when completed,” he said. “It involves the construction of a mall on an 866,500-square-metre site that will include a 26,000-square-metre indoor snow park and 300,000 square metres of shops, restaurants and entertainment areas.” Pallathody said that the above developments are only a few from the wide range of projects in the country, adding that the sector has also seen a growing number of construction projects related to expansion and redevelopment of existing structures.

french energy companies eye middle east market The country’s SMEs aim to share key learnings, best practices in the field of renewable energy By Hannah Jo Uy | Assistant Editor
iting the fact that many countries in the Middle East region are placing greater importance on improving energy efficiency and setting definitive targets related to renewable energy, Manoel Zenon, Trade Advisor, Infrastructures, Transport Industry, Business France, said that he believes French companies are well positioned to provide the technical knowledge and expertise required to achieve the regional public sector’s ambitious targets. Zenon said this is owing to the experience smalland medium-sized enterprises (SMEs) in France have in navigating stringent environmental requirements in Europe, which he said, they are eager to share with the regional market. Vinoth Ramanujam, Regional Sales Director, AEG, represents one such company. Sharing the company’s history in the region’s renewable energy sector, Ramanujam said that AEG was active in solar projects around seven years ago but that the influx of competitors from the east did not allow them to be competitive and that the company is now concentrating on UPS systems, with a solar division focusing on grid and storage applications. On whether energy storage will see the same downturn in price as solar panels, Ramanujam said that the main challenge is to educate people in the market to move away from “20-yearold specifications” and put a premium on quality over cost.

He said that the company aims to work with end-users and consultants during the specification and design stage to highlight its value as an additional layer of protection for sensitive equipment in critical
applications, such as hospitals and data centres. The added cost, he stressed, pales in comparison to the cost of repairing damage and downtime from loss of services. “Not having it means there is risk of damage and premature ageing of sensitive equipment,” he said, adding that this extends to HVAC equipment, which is particularly vital for operations of infrastructure in the region.
Sustainable cooling vital for smart cities, says MIT professor Carlo Ratti Associati highlights value of leveraging IoT technologies to optimise climate control; shares case study on customised environmental bubble By Hannah Jo Uy | Assistant Editor
lthough cities occupy only two per cent of the world’s surface, they host up to 50% of the world’s population and are responsible for 75% of global energy consumption and 80% of CO2 emissions, said Carlo Ratti, Professor, Massachusetts Institute of Technology (MIT), and Founding Partner, Carlo Ratti Associati, during his keynote address for the ‘Design and the City of the Future’ event on March 19, at the American University in Dubai (AUD). During a comprehensive discussion on how IoT is shaping the built-environment, Ratti underscored the important role that sustainable cooling must play in cities of the future. “Fixing energy usage and occupancy is vital,” he said, “when you think about how much energy you spend cooling your homes.” Ratti said trends in modern architecture are steadily placing greater emphasis on the importance of designing better ways to control temperature with minimum use of energy. This, he said, is especially the case in office spaces, which continue to evolve based on digital connectivity and individual
requirements. Providing an example, Ratti pointed to the redesign of the Agnelli Foundation headquarters, in Turin, Italy, where Carlo Ratti Associati developed a customised environmental bubble that provides personalised heating, cooling and lighting systems to occupants throughout the building. By leveraging IoT technologies, Ratti said the building was able to optimise space and energy usage. While the company was deeply involved in the overall architecture of the historic structure, Ratti said the implementation of key technologies related to heating and cooling was done by Siemens Italy, which equipped the building with sensors for different data sets, including the location of the building’s occupants, temperature, CO2 concentration and the availability of meeting rooms. Ratti said that he believes such an approach is scalable for other projects. “I really see it happening in high-end buildings,” he said. “Monitoring occupancy in a very fine way to create a climate around ourselves.” This, he said, is a best way to harness energy otherwise wasted from cooling in an inefficient manner.

amca takes the initiative to train professionals on the fEi metric The Fan Efficiency Index metric will require learning, as it has different complexities as an operating point metric, says Senior Director, Global Affairs, AMCA International By Ranjana Konatt
he Fan Efficiency Grade (FEG) metric was developed through AMCA and was published in the year 2010,” said Michael Ivanovich, Senior Director, Global Affairs, AMCA International, while highlighting the new Fan Efficiency Index (FEI) metric. The new-style FEI metric, he said, works with any amount of motor-driven load, be it with fans, pumps or air compressors and is also known as the wire-to-air metric. “The Fan Efficiency Index (FEI) metric takes a step further,” he said, “and is called the operating point
About the workshop instructors:

Steve Tredinnick, P.E., Member ASHRAE, is an industry leader advocating for increased reliance of District Energy facilities as a vital component of energy security, efficiency and grid stability.
metric.” For instance, he said, when a manufacturer produces a fan, its rating point is its operation, and that makes it a unique and exciting metric. “When an engineer is designing an air system,” he added, “the duty point is specific to the air flow, litres per Michael Ivanovich minute and pressure in Pascals.” The engineer’s software, Ivanovich said, will offer five different fan sizes, and FEI optimises the fan size, as per the pressure and airflow requirement. “One of the things AMCA realised is that the FEI metric is going to require a lot of learning in the industry,” he said. “But because it is an operating point metric, it has different complexities. Presently, we have developed a microsite to train people and help them understand the standard and the regulations in place for the year 2019,” he added, concluding, “If anyone is interested and wants to learn, we’ve made our standard 208, which defines how to calculate FEI.”

chEmours upbEat about dr-12 Low-pressure refrigerant is non-flammable under normal operating conditions and has a low-GWP, says company's representative By Surendar Balakrishnan | Editor
relatively recent report spoke of Chemours developing a lowpressure refrigerant – the DR-12 – which is non-flammable under normal operating conditions and with a low GWP. The report further described the refrigerant as offering stability and compatibility with polyester oil and with such metals as aluminium, copper and steel during tests carried out at 175 degrees C. It raised interest, given the prospect of a high-speed compressor working with a low-pressure refrigerant. The news of the
refrigerant raised the questions, ‘Could it be used in VRF systems, with its avowed non-flammable and non-toxic nature unburdening contractors and building owners from the need for installing leak detection and specific ventilation technology?’ Allison Skidd, Marketing Manager, Fluorochemicals, Chemours, clarified that the refrigerant is in the early stages of development and that several OEMs are evaluating it. “It has a GWP of less than 10,” she said. “And we expect it to be classified as ASHRAE Class A1. We have been encouraged by the feedback.”
When asked when it would be introduced in the market, Skidd said, “I can’t share timelines on when it would be released, and I don’t know the success report on equipment performance.” Skidd said the refrigerant would be a significant game-changer for particular types of equipment. Of course, she added, there could be technical aspects that may be limited to certain fluid systems.
coolth can contribute to lowering power consumption, says eco-structures The effectiveness of a building’s thermal mass is enhanced, when the concrete floor slab is utilised for energy storage, says Director, Eco-Structures International By Ranjana Konatt | Features Writer
ir conditioners operating in the GCC region account for 70% of available power capacity, making them the single largest consumer of energy, driving investment in hydrocarbon extraction, processing and import, said Dr Ghassan Al Nimry, Director, Eco-Structures International, while highlighting the benefits of TermoDeck, Eco-structure’s energy-saving solution, which involves saving energy by storing it (coolth) in concrete slabs during off-peak periods. Elaborating, he said, “Over the next five years, a further 70GW of power, costing USD 140 billion, is required to exclusively meet the demand for AC, with LNG feedstock costing USD 25-30 billion/year.” Reducing the installed AC capacity on new builds by 50%, he said, creates an effective demand-side and supplyside management strategy, which
extends along the entire energy value chain. On a national scale, he added, it also contributes to savings in capital and recurring operating costs, which exceed tens of billions of dollars. Explaining how TermoDeck works, Al Nimry said, the slabs that have the potential to store the energy can absorb surplus energy during peak times and radiate coolth, thus reducing the installed AC capacity and the total amount of energy needed to cool a building. Every single unit of cooling energy is now able to cool a larger space from the average 16-25 m2/TR for conventional AC to TermoDeck’s 35-70+ m2/ TR, he said. Elaborating further, he said, TermoDeck provides a large component of cooling during off-peak time, when ambient conditions are more favourable for cooling and when internal loads are lower compared to
Dr Ghassan Al Nimry
the daytime peak and chiller efficiency is higher – to be specific, higher annual chiller COP – so the amount of energy required or consumed and cooling efficiency is improved. In addition, elaborating on the benefits of integrating the TermoDeck system into the concrete structure, while using building structural mass to regulate internal temperature, Nimry said, “The effectiveness of the building’s thermal mass is enhanced by passing supply air through the slab even before it enters the room.” The slabs, he added, work as a heat exchanger between the supply air and the rooms. “As a result,” he said, “the effectiveness of the building’s thermal mass is enhanced as the whole concrete floor slab can be utilised for energy storage.” The reason is that the supply air is cooling it from the inside,
therefore the total surface of the cores exposed to the supply air is very big, he said. The concrete slab can effectively be cooled overnight and dissipates the surplus heat generated from people, lighting, computers and solar radiation that is stored during the daytime, he said. There is no risk of overcooling the room, as the cold supply air is cooling the slab and is, therefore, heated up before entering the room, he said, adding that during cold periods, the stored heat is used to keep the building warm overnight. And the concrete floors, he said, thus, act as an energy store. Elaborating, he said, “All this energy that has been stored in the slabs during the daytime can be removed during the night.” He added that this leads to a saving in installed cooling capacity by approximately 50%.
engie announces new version of the quantum air The new air-cooled unit is more efficient, quieter and lighter, company claims By CCME Content Team
NGIE Refrigeration is redesigning its entire air-cooled Quantum series, the company said through a Press communiqué. The new Quantum air models will be available worldwide from June 24, the company added through the communiqué. “The requirements for the refrigeration industry have changed in recent years,” said Jochen Hornung, CEO, ENGIE Refrigeration. “Our customers are placing increasing value on greater efficiency and performance in their chillers, for example. We are accommodating these changing conditions by redesigning our aircooled QUANTUM series.”
On the launch date, ENGIE Refrigeration will offer 28 basic models of the Quantum Air. Fourteen of these models use the refrigerant R-1234ze, and 14 models use the refrigerants R-134a and R-513A; all of them require lower quantities of refrigerant, the communiqué said. Like its predecessor model, the revised chiller is ideal for use in a variety of industries – from automotive manufacturers and suppliers to the chemicals and pharmaceuticals industry, industrial production and data centres, the communiqué said. According to the communiqué, customers will benefit from additional important advantages in the future – ENGIE Refrigeration has combined the individual machine components in a new way, so that the Quantum Air surpasses even the exceedingly high efficiency of the current series. The chiller is also suitable for applications from 250 kilowatts to two megawatts, the communiqué quoted the company as saying, adding that with this refrigeration capacity, the Quantum Air outperforms not only its predecessor but also all air-cooled chillers from other manufacturers that are currently on the market.
Carel’s provides noninvasive approach to sensitive castel project Company shares the inherent challenges in undertaking HVAC-retrofit projects in historical architectural structures By Hannah Jo Uy | Assistant Editor
ny work on HVAC systems in historical buildings and in museums is critical by definition, said Giandomenico Lombello Giandomenico Lombello, Group Managing Director, Carel. “The simple fact of having to work in contexts with considerable architectural and structural constraints makes these operations very complex, and requires the use of tools and products that are suitable for conserving our artistic heritage,” he said. Lombello shared that recently Carel has completed a project in Castel Sant’Angelo, a historical building in Rome, installing a measurement and supervision system. “The customer’s request was very challenging and required the work to be non-invasive and totally concealed from visitors, while ensuring high standards of efficiency and high reliability,” he said. Lombello explained that the rooms, due to their structure, had different thermal and humidity loads, and the works kept in the building required different set points for optimum conservation. “The solution,” he said, “made it possible to fulfil the customer’s requests regarding the aesthetics of a historical site and the safeguarding of works of art, while at the same time complying with the highest standards of efficiency, reliability and system performance.”

If this had not been the case, it would also have been unable to make its long journeys through the world's oceans without having to feed. The latest generation of centrifugal fans at Ziehl-Abegg is now benefitting from this knowledge of biomimicry, the communiqué said. The developers at Ziehl-Abegg, the communiqué said, also drew inspiration from Professor Claus Mattheck. The 'tree whisperer' or 'tree pope', as the media call him, creates a bridge between nature and technology. The professor is, after all, a pioneer of the science of biomechanics. Trees are a prime example of optimum strength with minimum use of materials. The five blades of the centrifugal ZAbluefin fan, the communiqué said, merge into both the cover and back plate in exactly the same way as trees grow upwards – at a slight radius to the ground. This is scarcely visible to the naked eye, because the curves, which mimic a tree, are minimal. Nevertheless, these bionic approaches in the blade transition provide the same strength as heavy wings – enabling the use of materials to be significantly reduced. Less material consumption in production also means a lower carbon footprint, the communiqué said. According to the communiqué, the air flow in centrifugal fans hits the fan blades at different angles, depending on the volume flow.

an angle to the opposing current, strong turbulence would result in the water separating from the fins. “High flow losses and noise are characteristic features of strong turbulence,” said Dr Walter Angelis, Technical Director, Ziehl-Abegg. The design of the fins on a humpback whale has been optimised over millions of years. That’s why the leading edges of the whale fins contain golf ball-sized nodules (technical term: tubercle). This allows an animal weighing 25 to 30 tonnes to swim very quickly and nimbly using its long pectoral fins. “We recreated this aspect at the leading edge of the fan blades and implemented it in the form of a rippled surface,” Angelis said. The flow engineers also took a closer look at the whale’s tail fin, the 'fluke', the communiqué said. The V-shaped contour of the tail fin section, the communiqué said, delays any potential flow separation, which enables the fan to be used for numerous pressure ranges. The latest generation of centrifugal fans at Ziehl-Abegg, the communiqué said, is now benefitting from this knowledge of biomimicry.

ACEEE: TRUMP 2020 BUDGET WOULD JEOPARDISE CLEAN ENERGY US President’s proposed budget would mean a drastic 86% cut in new funding for the US Department of Energy’s office By CCME Content Team
he Trump administration’s 2020 budget request, released on March 12, proposes a drastic 86% cut in new funding for the US Department of Energy’s office that handles popular and cost-saving energy-efficiency programmes, the American Council for an Energy-Efficient Economy (ACEEE) said through a Press communiqué. It would also seek to fund the popular ENERGY STAR programme entirely from user fees, the communiqué added. “This proposal, if enacted, would cause Americans’ energy costs to rise, while killing jobs around the country,” said Steve Nadel, Executive Director, ACEEE. “Energy efficiency directly supports 2.3 million US jobs and, indirectly, many more. In addition to putting these jobs at risk, these cuts run counter to the administration’s own goals of promoting economic growth and reducing wasteful spending. We hope Congress will stand up for business owners, workers, and consumers by blocking the proposed 2020 budget cuts.” The administration proposes USD 343 million in new funding for the Office of Energy Efficiency and Renewable Energy – an 86% cut from the prior year’s funding level, the communiqué said. The office runs many programmes that could be severely impacted; as usual, it would carry over additional funding from previous years, the communiqué added. While the US Department of Energy has not yet released detailed numbers, the US Environmental Protection Agency would eliminate the SmartWay programme, Combined Heat and Power Partnership, and other voluntary programmes, as well as seek to make ENERGY STAR self-funding and cut funding for its vehicle emissions programme. ACEEE’s Federal Energy Efficiency Programme Fact Sheet estimates the impacts of seven programmes:
Winters requalifies for ‘Best Managed company’ status
1. The US Department of Energy (DOE) appliance standards programme sets minimum efficiency levels for about 60 consumer and commercial products. It already saves the average family almost $500 each year in energy and water bills. 2. The US Environmental Protection Agency vehicle emissions programme sets emissions requirements and fuel economy labels for cars and trucks.
