he food control department of Dubai Municipality has revealed that it has begun the process of mapping cold storage warehouses as a precursor to inspecting them to ascertain whether they represent a source of abuse of temperature-sensitive food products or not. Even then, a senior official said, the agency would only look at lead indicators, like quality or test results of food samples, and work in reverse, because food can come from warehouses located outside its jurisdiction.

And therein lies the issue. The United Arab Emirates and the wider GCC region, for that matter, perhaps need a broader programme for mapping all warehouses to emerge with an airtight food safety programme. Often-times, food abuse is not the result of faulty refrigeration equipment but how they have been specified, installed and tested and commissioned, and eventually how they are operated and maintained (O&M). Prior to that, the very design and construction of the warehouses from civil and structural perspectives need to be evaluated. There have been instances where a food establishment has been fined for a food safety outbreak arising out of temperature abuse, when the fault probably is with the contractor, who likely cut corners to save on costs, which can affect O&M. At present, neither the contractor nor the owner is liable, which likely emboldens them to sidestep necessary measures in the proper design and construction of what really are mission-critical warehouses from a food hygiene perspective.

The region also could consider evolving a framework on transport refrigeration, Truck body hygiene and temperature control are essentials for upstream food safety.

If the two are compromised during long-haul, trans-border movement, the damage can be substantial, rendering most downstream initiatives as less effective. In the case of temperature control, a core issue is the age of the fleets. Typically, a reefer trailer’s lifespan is six years, which can be extended through refurbishment to eight years. In Europe, new regulation allows for 10 years of service, and that is because the methodology of manufacturing of the mounted bodies has improved, and because as always, they carry their wares in temperate ambient conditions. In the GCC region, on the other hand, reefer trailers older than 20 years are reportedly still being used to haul temperature-sensitive food products in high-ambient conditions. Over that long a period of time, the insulating property of the mounted body is likely diminished, possibly exposing food products to high temperatures. In that context, transport refrigeration as a topic needs to be discussed with vigour and a sense of purpose.

OVER STORY

With special attention to the HVACR sector, the story unravels the myths surrounding blockchain technology and attempts to gauge industry perception and the success of existing platforms, which use this technology.

By Ranjana Konatt

October 2018

I

n April 2018, the UAE Government launched the Emirates Blockchain Strategy 2021, where 50% of government transactions are to adopt a blockchain platform over the next three years. Recently, Smart Dubai (SD) and the Department of Finance (DOF) integrated blockchain technology into the online payment portal, DubaiPay, to allow reconciliation and settlement transactions to be performed in real time, officials say.

Andrew Schumer, Managing Director, Black Wit Cyber Solutions, applauds the UAE government for its openness to the technology. Schumer says: “The UAE is incredibly forward in the way it works. What’s interesting is that the UAE is pursuing the technology to test it, while putting money where their mouth is.” And, even though he’d like to see regulators continue to

work with the technology, he says that people are often confused about what blockchain means and its implications, if applied to the HVAC industry.

More than 99% of people associate blockchain with cryptocurrency, says Nesar Reza Khan, Executive Director, FP Global Developments, while highlighting the myths surrounding the application of blockchain to the HVAC industry. He says, “For a long time, blockchain was seen as a threat, and its application was believed to have the potential to introduce corruption and money laundering into the trading end of the HVAC industry.” The most common mix-up, he says, is with Bitcoins and cryptocurrency. “Blockchain is a software, a tool used as a database, while cryptocurrency is an online trading platform for assets like stocks, shares and bonds,” explains Khan.

Drawing connections between cloud computing and blockchain

technology, Harold Dickenson, Manager, Visualisation & Immersive Technology Group, AECOM, Middle East, says, “Cloud computing was the first gateway to blockchain and refers to the decentralisation of data-storage.” If applied to the HVAC industry, Dickenson says that it will create a whole new level of data sharing. He says that it is good to be optimistic about the technology; however, we must be aware of its positive and negative effects.

Joseph Aamidor, Managing Director, Aamidor Consulting, says that the differing views on the technology, can often leave a person confused, At its core, blockchain is a digital ledger.

What’s interesting, he says, is that the information fed into the system will be anonymised and immutable. Each stakeholder, he says, will have access to the system and the transaction history, making it both secure and easy to access.

October 2018

Arvind Srinivasan, Head, Global Strategy, Emudhra, says the first issue that the application of blockchain will address is the low quality of work within the industry.

“Blockchain will raise the standard of output with regard to manufacturing, supplying, installation and even servicing,” he says.

Pointing to the food-reviewing portal Zomato, he stresses the importance of having an open system and says: “Have you wondered what makes, Zomato successful? It is because of its reviewing and rating service, which is kept open to everyone.”

Khan, too, stresses on the need for an ‘open-for-all’ system and refers to it as the only way to fight corruption and wrong practices by middle men in the HVAC industry. He says that the technology will threaten corrupt middlemen and says, “The industry is fraught with ‘middle man’ corruption and this does not stem from manufacturers or end-users.” Referring to it as something intangible, he says that blockchain will weed out corruption. “Transparency is the greatest benefit, which translates directly to greater efficiency and lower costs,” he says. However, blacklisting a contractor will be an ‘after-the-fact tool,’ used to protect manufacturers in the future from fraudulent methods of working. This knowledge, he says, will only exist after a contractor has defaulted with a manufacturer. “Blockchain has to be integrated into every step of the HVAC industry," Khan insists. "If done well, there will be no room for blacklisting, as the technology will not allow a default in the first place.”

The greatest beneficiary of blockchain’s integration with HVAC, he adds, is the enduser, who could be either a developer or homeowner.

Roadblocks to the application of blockchain in HVAC “MEP contractors might be reluctant to share information on their projects,” highlights Sameer Daoud, CEO, MECIC, while talking about the challenges to the implementation of the technology. If left optional, he says, there could be a high chance where many won’t even attempt to make their presence known on the system. Aamidor echoes Daoud, saying that building owners and operators, too, might not be keen on sharing their performance data; however, he adds that the system might maintain some level of anonymity for them to do so. Daoud believes that transparency and sharing project details will give the HVAC and MEP

contracting space the much-needed push to innovate. “Cost is another influencing factor,” says Aamidor, who points out that, while the technology is thought to be the panacea, the cost and energy demand of running servers and processing blockchain transactions will be the other challenge to its smooth application.

In addition, Sougata Nandi, CEO, 3e Advisory, points to timely information updates as crucial to the blockchain. “If HVAC equipment is not registered or updated on the developer’s point of the ledger, then it falls off the blockchain,” he says. Calling it a disciplined task, he highlights that the technology alone does not blacklist a defaulter; instead, it just records the fact that a default has happened. Nandi also points to hacking as a huge threat and says, “Along with the safe storage of data, protecting it from being hacked is a major concern.”

He advises that any government adopting blockchain must ensure an investment in infrastructure to protect the system. In addition to hacking, Bobby Krishna TM, Senior Specialist, Food Permits and Applied Nutrition Selection, Dubai Municipality, singles out the overreliance on technology as a major challenge to the application of blockchain. He says: “There is an over-reliance on the internet, for instance, if there is no internet, the whole system stalls. However, in the case of the Food Watch Programme, we do have backup plans to ensure that it never shuts down.” Food Watch is an initiative by the government of Dubai, which uses blockchain to increase traceability.

Elaborating on the over-reliance of technology, Schumer says that today, there are ways in which the internet can be made redundant. Highlighting Content Delivery Networks (CDNs) as a useful tool to send out updates, he says, “CDNs are another breakthrough and are networks that use proxy servers, which have their own datacentres.” Today, he says, CDNs are widely used by cellular companies to send out software updates to their users.

‘Handling of information in Blockchain is crucial’ Dickenson highlights the implications of the technology on its stakeholders and explains with an example. He says: “Imagine you had a health condition and that it was recorded in a system. You don’t suffer from it anymore; however, every time you travel to a country where the condition is not allowed, it shows up on the system.” And this, he says, is bound to affect the stakeholder, no matter how well-placed the technology might be.

Raising a crucial issue, Dickenson says, “You don’t want one thing to affect your entire future.” He adds saying, “If when I was young I went with the wrong crowd, should that mar my record for good?” Here, he says, is where legislation plays a crucial role and the application of blockchain to any industry, demands several levels of security and is something that needs to be developed.

Echoing Dickenson is Nandi, who refers to trust and duplication, both as independent issues. He says, “[Blockchain technology can avoid] wasteful hours spent in updating the same information by multiple parties and can ease the access to information; however, if someone uploads a wrong set of information that goes undiagnosed, then holding blockchain technology responsible would not be fair.” Checks and balances, he says, are going to be crucial for the success of blockchain. He also points out to IoT and its extensive use in blockchain and says, “For the smooth link of IoT to the blockchain, it needs to be customised on a case-to-case basis.”

He says that IoT will enhance traceability,

improve manufacturing and will power a paperless society.

Blockchain and the Food Watch Programme

Sameer Daoud

Sougata Nandi

Bobby Krishna believes that blockchain is not the immediate solution to the lack of transparency in an industry. Drawing a fitting analogy, he says, “Blockchain is like Windows, an operating system on a computer, which helps get work done.”

The Food Watch Programme, he says, is something that uses blockchain technology, but eventually, the success depends on the data collected and how it is linked to the food chain industry. Calling the Food Watch Programme an excellent initiative, Schumer discusses how it might be too soon to tell whether the platform is a success. He says, “It will take time for people to see the true value of the Food Watch Programme.” What is visible, he says, is only the front-end of the application and the idea is to track every choice related to food safety and make it available to everyone.

OVER STORY

Bobby Krishna TM

Richard Sprenger

“Consumers and the general public are still not able to differentiate among blockchain technology, cryptocurrency and digital currency.

“The Dubai Smart Government is running 20-plus pilot projects with different government entities, while analysing various Proof of Concepts (POC). The Emirates Blockchain Strategy can be applied to any sector and will result in the conversion of information into valuable assets. The application of the technology will make manual storage redundant and will eliminate any risk related to the forging and loss of information. The strategy uses multiples kinds of blockchains, for instance private blockchain, which is visible to only a certain process; public blockchain, which is kept open to everyone and hybrid blockchain, which is a mix of private and public strategies.

But one must remember that the benefit derived from the application is relative to the nature of its application and the way it is used.

The beauty of having the technology is that as an open source and an entity, it is not owned by anyone and, hence, if applied to the HVAC sector it will definitely improve transparency in transactions among consultants, contractors and even end-users.”

Echoing Sprenger, Krishna adds that since the adoption of the programme, the technology has benefitted the system and that Dubai Municipality is in the process of making updates to it. “The vehicle certification will trace all the food transport vehicles, anywhere in Dubai, and will keep an eye out for the places they supply food to,” Krishna says. He adds that now, since the technology is in place, Dubai Municipality is exploring new models and is thinking of how best it can use blockchain in a cost-effective manner.

“I have to admit that initially, we were sceptical about the shift, because the Food Watch Programme demands complete transparency,” Krishna says.

And initially, he says, a number of people were afraid to share data, as they were afraid of being exposed.

He adds, “The platform is being made more user-friendly, and we must always remember that the technology and its application is a long-term framework.”

Takeaway message

Marwan Abu Ebeid

Krishna adds that today, “Data is governance” helps to get to the root of a particular problem. Speaking on the performance of the Food Watch Programme, he says, “The Food Watch Programme is relatively new and is a platform where every stakeholder can access the system using his or her personal account.”

Richard Sprenger, Chairman, Highfield Middle East, refers to the programme as an ambitious and world-leading initiative and is hopeful that the platform will make a significant contribution to food safety.

He says, “The Food Watch Programme will provide an opportunity for stakeholders to participate completely while recording information in a timely fashion.” However, echoing Schumer, he says that it might be too early to confidently claim that the technology has achieved the stated objectives. But he asserts that it has the potential to provide evidence in a few years’ time.

“Today, advanced HVAC Management and Control Systems use IoT to gather buildingand energy-related data every 60 seconds.

This will enable blockchain to store the highly confidential data securely and ensure interoperability.”

Shilpa Basappa, Principal Engineer, 75F

Marwan Abu Ebeid, Senior BIM Manager, Turner Construction, believes that blockchain shows tremendous promise and proves to be most advantageous when applied to any supply chain across any industry.

Srinivasan shares the same feeling and insists that the application of blockchain to HAVC should show how a manufacturer, supplier, contractor and consultant have performed on a project and he says this will have serious implications for the future.

Calling it the greatest invention after the internet, Khan says that blockchain has an enormous amount of potential, while making a case for education and awareness. He says: “Education and awareness play a key role in ensuring that all the stakeholders understand, appreciate, adapt and innovate within the blockchain revolution as opposed to distancing themselves, thereby putting themselves at risk. If done well, the technology will most likely be the greatest anti-corruption tool that exists.”

‘The value of

Heat Island mitigation C is hidden from ould you provide me with an overview of the work GCCA is doing around the world on the issue of Urban Heat Island?

We are a nonprofit, and we do a lot on urban heat island mitigation, but the main focus is on reflective surfaces – roofs or walls. There has been increasing recognition in hot and cooler cities that extreme heat is a major problem, with significant research in over a year and a half that highlights the cost of inaction for cities to quantify the meaning the full way, not just to avoid the negative but to achieve positive outcomes. Estrada et al 2017, Nature, Climate Change – found that heat doubled the cost of local climate change. A median city of 1,700 studied would pay an additional 5.6% of its economic output by 2100, if heat goes unchecked.

decision-makers’ Kurt Shickman, Executive Director, Global Cool Cities Alliance (GCCA), speaks exclusively with Climate Control Middle East, on the importance of Urban Heat Island mitigation, the need for collaboration between the public and private sectors, the uptake of cool roofs in the last decade and bottlenecks facing adoption of cool pavements. Excerpts from the interview with Hannah Jo Uy… visits. In a paper, published in the Journal of Climate Change , they found that a moderate deployment of a cool roof and pavement programme would have a payback 12 times its cost. This includes maintenance.

There is a tremendous amount of benefit.

The challenge that must be eliminated is the fact that a lot of the value is hidden from decision-makers. It isn’t apparent on profit and loss statements. There’s a huge role here for policy to make people aware of these benefits and also to transfer the benefit to decision-makers through incentives. Until we realise the benefit, we won’t have adoption at the pace we need. We are doing a lot to raise awareness, to make cities aware of the benefits beyond what they are looking for.

Has awareness grown, owing to recognition of the economic paybacks that adoption of Urban Heat Island strategies might have for each respective country?

At first, cool roofs were driven by energy considerations and energy policy/codes – that value energy savings. When you peel back the onion and look at the cost benefit, you see something in the order of one-anda-half to one, in favour of cool roofs on base energy, not even peak demand reduction.

The cost benefit varies a lot by climate but is nearly always above 1:1, even in colder areas. In the US, the economic payback is anywhere between zero and six years on base energy demand reduction alone.

For energy savings with health requirements, it’s between 7x and 12x compared to the cost. We can look at data that shows reduced heat deaths and hospital

If you reflect light from the pavement, you may increase natural lighting, which reduces lighting load but increases cooling load, because more solar radiation enters a building real challenge. Heat is a weird topic in that sense. In New York, in the Urban Heat Island [meetings], aside from us there are also people from New York Emergency Services, police, city architects and planners, health department, community groups, researchers, universities – all these different groups have different ways of talking about what they do. It’s getting folks to think about it, as a common problem. That is easy to say but challenging to put into practice.

It’s almost never the numbers that drive it – it’s the stories. I won’t say the city, but I had a conversation with the public-safety group – the police, fire [department] and first responders. They started to look at the issue of heat in cities and found that there is a statistically significant increase in domestic violence calls in hotter areas. There is an actual impact on crime, if we do something about the heat. There’s a lot of different ways to look at it, there’s no one message.

Could you elaborate further on the role that policy plays in this regard and the need for collaboration between the public and private sectors?

Policy doesn’t mean regulating, it could be incentivising. There are different ways to structure policy, some voluntary and some involuntarily – a mix of the two is needed.

So far, no one is setting the ceiling, they are setting the floor. In most places, with a few exceptions, bringing up the floor doesn’t hurt the manufacturers.

We all default towards what is easy, to use and get benefit from one technology and strategy – but it’s a systems approach.

A lot of things need to work in tandem to make change. That’s hard to do without

collaboration among policy makers, researchers, to look at [the issue in a] more systematic way.

We don’t go and say, just do a cool roof; it has to be symbiotic with Green infrastructure.

You can’t go in with one solution; you need a policy-maker to spur that conversation, especially in the developing world. It’s also about the industry, manufacturer and the people on the ground, including the construction industry; it is important to make sure their voices are heard.

Could you comment on the uptake of adoption of cool roofs and pavements today, among contractors and consultants across the United States?

We are seeing two big changes in the market over the last 10 years. With regard to the membrane roofing, thermal plastic membranes that are placed on commercial buildings, there is the EPDM rubber, primarily black, and TPO and PVC, primarily white. It is naturally that colour. What we have seen, in the last 10 years is a flip-flop in the market, from being predominantly EPDM-dominated, to one dominated by TPO and PVC. This is driven by positive economics but also the fact that a cool roof is a LEED credit with the USGBC. So in UHI, there is a huge shift in what’s being specified for commercial roofs.

I will say from 35 to 65 the shift went from 68 to 32 in favour of white products. Not just in the warm climates but all the way up to the Canadian market there is a fundamental shift. Over the last five years, we have a couple of cities that have taken the next step.

In the US, in most of our residential peak roves we mostly use asphalt shingles, like black asphalt, some tar and granules.

Cool granules have been in the market but were prohibitively expensive. Some cities mandated cool roofs for residential developments. Two markets actually spurred a tremendous amount of innovation, to bring a product at a more mid-tiered price. There is also a lot of growth in areas outside where it is mandated. LA mandated cool roofs in 2015. A manufacturer told me they sold more cool roof shingles in a city outside LA, which is not under that regulation, than in LA. We are starting to see people do something about it.

Have you observed the same positive trend in cool pavements, as you do in cool roofs?

Cool pavements are much trickier. There is a lot less human interaction with the roof

than pavement. If you reflect light from the pavement, you may increase natural lighting, which reduces lighting load but increases cooling load, because more solar radiation enters a building. It could have more, or less, impact on pedestrians. You may decrease temperatures on the street level but increase thermal load on pedestrians.

LA, Melbourne and Tokyo are doing a lot.

They find the best conditions you can put a pedestrian in are cool pavements with ample shade trees and structure-reflected. Shady spaces [offer] the biggest reduction on a pedestrian’s thermal load. It’s worse when you have barren area. The same intervention could be for the best or for the worst. It depends – it’s really not a one size fits all.

However, we can’t just not address pavements – they are a huge part of our cities. On average, one in every three metres is some kind of pavement. There is a significant, impactful urban heat island mitigation benefit from cool pavements, but where we are, in terms of the technology here, there is also a global warming impact that may outweigh the benefits. There is a need to innovate. When you turn a surface from dark to light you create a cooling effect on earth but also a warming impact on the atmosphere. If I create this cooling effect on a road, from dark to light that cancels the warming effect of x tonnes of greenhouse gases in the atmosphere. There is a sustainable way to look at this. When you factor [the global warming effect on the benefits], it trumps it 150 times.

A lot needs to be done on cool pavements.

We need to be mindful of how they are applied– specifically, as well. If your goal is urban heat island mitigation, there is tremendous benefit. If you were to ask what I recommend as a minimum, for cool roofs, I would say “yes” in nearly every climate zone, unequivocally. For the same question on pavements, I wouldn’t say that’s my answer. I’m not against it. For me, what I would like is the transportation department to study and look at cool pavements. We do need to study the local-level impact of cool pavements. No question, we need an UHI solution for pavements. It’s too big a part of the cities, but we can’t just say, “Make them all light coloured”. We need a much better local understanding.

he ICE Group's Mission Statements and Objectives, which appear below, are taken directly from their materials:

The Independent Contractors Exchange Group The Independent Contractors Exchange Group is a group of contractors specialising in installation, operation, repair and maintenance of large commercial and industrial cooling systems and building and process control systems. ICE Group's mission is to improve our people, our companies and the industry through technical support and training, sharing of best practices and maintaining positive relationships with strategic partners in the industry.

ICE Group's Objectives 1. Improve our people through education and training, technical support and sound leadership.

2. Improve our companies through education, sharing of best practices and best management practices.

3. Improve the industry through positive engagement with stakeholders and partners.

4. Assemble a group of the best companies with the highest quality people, doing the highest quality work and with the highest ethical standards in the industry.

The power of this group is unprecedented.

The group consists of members from the 50 most proficient independent chiller services companies in the United States, who come together annually to share technical and business best practices, so that the group members’ customers receive the finest solutions and services available in the industry. The last meeting was the most technically encompassing meeting I have attended in many years. The sharing of information in this group is something I have never seen in the HVAC industry. It is also something, unfortunately, that I have never seen in the Gulf region. It seems to me chiller services companies, whether OEM or independent, rarely if ever, want to come together and collaborate on technical and business best practices. In my opinion, this is what will thwart us in the Gulf region to reach our full potential, to be the very best that we can be. It is a disservice to the entire region, and we should all try and put aside our commercial and competitive issues and try to make the Gulf region’s District Cooling

The power of groups:

we all need to work together in the Gulf region In all of my years working in the HVAC industry, I have known that groups and shared information can sometimes be very powerful. I feel that even more so now, since I recently had the pleasure of attending the Independent Contractors Exchange (ICE) meeting, from September 12 to 14, 2018, in Tampa, Florida, USA.

and chilled water industry, number one in the world, because we can. Most readers of this are all members of or are familiar with, IDEA (International District Energy Association), which is a great organisation; however, the ICE group brings additional, in-depth, technical and chiller knowledge and experience of service, repairs and O&M of chillers and chilled water systems that complement and bring value above and beyond what other groups do. The ICE group specialises in chillers, something no other organised group does. I would like to outline what the ICE group covered in the intensive three-day conference that I attended,

highlighting just some of the topics covered, so readers have an idea of the power of this group and how it would benefit us in the industry to develop a similar group in the Gulf region.

The topics covered in the meeting were: 1. Safety and rigging 2. EPA rules and refrigerant conversions 3. Oil-less magnetic centrifugal compressors 4. York YT upgrades with non-York microprocessor control systems for better performance 5. Smart oil-less magnetic chiller retrofits for best efficiencies in the industry 6. Alternatives for chemical water treatment 7. Inductive absorbers to prevent bearing failures with VFD technology 8. Service management and accounting management 9. Internet 10. Bitzer screw compressor retrofits with VFD technology and microprocessor upgrades 11. Financial risk management 12. Refrigerant recovery/recycling to ARI 700 Standard 13. Clean up of refrigerants to ARI 700 standard in the field 14. Heat recovery chillers vs boilers 1.1 kw per tonne vs 3.7 kw per tonne for boiler heating.

What was also very interesting in this conference is that every major OEM of chillers participates in the conference and introduces their latest technologies and training to the group. In fact, the group receives preferential training and retrofit packages from all the major OEMs that no other service organisations have access to. The group also supports each member with sharing of resources, such as human resources, parts, service bulletins, manuals and technical solutions that no single organisation could amass, on each and every major chiller manufacturer’s equipment.

The group also has a ‘Technical Questions’ service, whereby any situation regarding chiller service, repair or troubleshooting, can be sent via email and someone who specialises in the subject, within the group’s over 1,000 individual members, will respond with the answer to support the other group members. This is the power of having the ability to reach out to over 1,000 of the most highly skilled and trained engineers and technicians, worldwide.

This is the power of independent chiller specialist companies as a group organisation. No single company, whether an OEM or engineering firm or chiller specialist company, can amass the collective knowledge that this group has on all OEM chillers and can react as quickly to support group member companies. The group collectively is by far the most technically competent group of talent in the industry and can solve any chiller issues quickly and professionally.

Having pointed out the massive value of a group such as ICE, I feel we should come together in the United Arab Emirates and Gulf region and form some regional group made up of DC companies, service companies, FM companies and OEM companies, to work together and collaborate for the greater good of the DC, chilled water plant and chiller industry in our region.

My whole purpose with this article is to impress upon the readers the importance of a ‘master mind/master community’ that could

dramatically assist us all in working together to make the United Arab Emirates, and the greater Gulf region, leaders in the chiller and chilled water plant industry. If anyone would like to form a group that addresses chillers and chilled water systems on a higher level, I, for one, am willing to participate in any way that I can.

The uptake of VRF technology in Saudi Arabia

What’s being said on the ground in the Kingdom…

More than 70% of energy is being consumed by air conditioning in Saudi Arabia. As a country, we are now looking at a big initiative to retrofit old buildings. This project is coming up, and we are thinking of achieving as a consultant more than 50% reduction in energy by 2030.

Khalid A Al Mulhim, Business Development Director, Suhaimi Design - Protecooling, Saudi Arabia

When it comes to labelling of products, we think there is always five percent that is trying to cheat. But the problem is that 75% will wait till the five per cent is caught, so compliance is slow.

If we compare maintenance between VRF and conventional systems, we cannot give figures till we have the typical size of the building and design. But maintenance for VRF is less than conventional system with regard to time and the situation of lack of labour.

Dr Moataz T Bakheet Director, Madinah Office & Western Region Projects, Zuhair Fayez Partnership

Out of 4.2 million residential units in demand worldwide, only seven per cent are inverter-based, so we have a long way to go.

Rui Fonseca, Consulting Sales Manager, Daikin Saudi Arabia

Michel Farah, Vice-Chairman, Eurovent Middle East

The technology here is very efficient when you have partial use, but when you have full load then it is comparable to other systems.

Dr Moataz T Bakheet Director, Madinah Office & Western Region Projects, Zuhair Fayez Partnership

I believe SEER should be followed. Part load is not being considered, where the most efficiency possibilities are.

Michel Farah, Vice-Chairman, Eurovent Middle East

11.2 EER for VRF is something we have to improve if we want greater energy efficiency in Saudi Arabia.

Rui Fonseca, Consulting Sales Manager, Daikin Saudi Arabia

The building physics is what drives the design of a building. SASO should not only assign targets for refrigerants with machine efficiency but also we need smart clever building physics, particularly with residential buildings.

Kristian Unger, Deputy Project Director, Faithful Gould

The future is about VRF. Initially, I saw only one project. Now, year after year, there is an increase in VRF projects by 30-40%, which I did not see in other systems.

Hamed Al Arfaj, Managing Director, Air Conditioning Division, Al Asasyah Basic Electronics Company, Gree Air conditioners

The future is where the systems will survive if they have a low refrigerant consumption. As much of possible, the amount of refrigerant in the system must be reduced.

Ahmad Arabiat, Research & Development Engineer, PETRA Engineering Industries Company

Training on proper installation of VRF systems is crucial. At the time the contractor is doing the job, we as manufacturers have to be there on piping, welding and commissioning.

Amr ElMasry, Regional Director, Marketing and Strategic Projects, Carrier Middle East Limited

It is important to be careful during the installation of VRF systems.

We must try to minimise the welding joints as much as possible; and the work needs to be carried out by professional contractors to ensure no mistakes are made.

Ahmad Arabiat, Research & Development Engineer, PETRA Engineering Industries Company

Passive reduction by improving envelop is very important, as is the role in ensuring the design is properly implemented. If all is done in a controlled manner, there is huge potential to reduce the load.

Mohamed R Zackariah, Chief Consultant, Suhaimi Design – Protecooling, Saudi Arabia

If you are using certified products, use certified contractors. Don’t allow any VRV to be installed by someone who had not received training.

Rui Fonseca, Consulting Sales Manager, Daikin Saudi Arabia

If installation of VRF system is done properly then it is a case of simple maintenance in the upcoming five years.

Amr ElMasry, Regional Director, Marketing and Strategic Projects, Carrier Middle East Limited

Theoretically, VRF can be applied to any project. But first of all, we need to understand the application, and we have to start with good design, and then implementation is going to be easier in terms of supply and contracting.

Averting the risk of

asphyxiation, acute toxicity

VRF/VRV systems have many advantages over traditional DX splits and waterbased systems, but the risk of refrigerant leakage in the occupied spaces should be fully assessed and provisions made, writes Dr Jason Shilliday

T

he first synthetic refrigerants, CFCs (with R-12 being one of them) were invented in the 1930s. They rode on the virtues of safety, in terms of being non-toxic and non-flammable gases, and on having the correct pressure-temperature relationship, which made them suitable to be used as refrigerants.

A lot has changed since that first batch of gases were produced. The Montreal Protocol, which came to be established in 1987, placed restrictions, then a ban, on the use of CFCs, owing to their high ozone-depleting potential (ODP). Their replacements, the HCFCs (with R-22 being one of them) were less damaging but still were restricted under the same international protocol and eventually phased out. The next batch of replacements, HFCs (R-410A, etc.) are currently being phased out due to their high global warming potential (GWP), as restricted by the Kyoto Protocol (2005).

HFOs (R1234yf) and HFCs with lower GWP (R-32) are the latest advancements in the area of synthetic refrigerants and have mostly been accepted due to their low GWP; however, issues have been raised due to their mildly flammable nature.

Different countries have applied different legislative measures to ensure the safe use of refrigerants in HVACR systems, and some – case-in-point the European F-Gas regulations – have gone a step further and regulated their use.

26

October 2018

Leaks of synthetic refrigerants from refrigeration and air conditioning systems are harmful to the environment due to their GWP, but they are also harmful to people. There are risks due to some of the gases being toxic and flammable, but there is also a high risk of asphyxiation in a confined space due to a leak. There would be significantly less health and safety risks in buildings, less environmental damage, and also more economical advantages if the refrigerant leakages from these systems were controlled more effectively. Early refrigerant leak detection is one way in which to prevent heavy leakages from occurring. It would alert operators to any refrigerant leak, giving them ample time to carry out repairs. That way, the quantity of refrigerant lost to the atmosphere would be limited.

In this article, I wish to explain some of the international standards related to refrigerant safety and use, which hopefully will help at the time of designing buildings or cooling facilities to international standards.

The advancement in the operational efficiency of direct expansion and VRF/ VRV systems has brought refrigerants in large volumes much closer to the public.

VRF/VRV systems have many advantages over traditional DX splits and water-based systems, but the risk of refrigerant leakage in the occupied spaces should be fully assessed and provisions made in the design to reduce the risks of acute toxicity, asphyxiation and flammability-related hazards.

Enter EN378 EN378 is a European standard that was updated in 2016 to include further design information to be considered for the planning stages, when using refrigerants with a low-flammability classification (A2L). The standard was also updated to include a design methodology on how to calculate the maximum refrigerant charge that should be applied to a refrigeration or air conditioning system. If an indoor unit or pipework passes through an occupied space, the whole gas charge could potentially escape into this space. The EN378 standard sets RCL (refrigerant concentration limits) to reduce the risks of acute toxicity, asphyxiation and flammability-related hazards. The following terms are required: QLMV: Quantity Limit with Minimum Ventilation in kg/m3 QLAV: Quantity Limit with Additional Ventilation in kg/m3 RCL: Refrigeration Concentration Limit in kg/m3 Table 1, in the opposite page, shows some of the common refrigerants listed in the standard, along with their allowable refrigerant charge. The total refrigerant charge divided by the room volume should not exceed these values. If the charge limit is exceeded, appropriate measures, such as ventilation (natural or mechanical), safety shut-off valves, safety alarms or gas-

system should be used in the hotel room. The maximum VRF/ VRV system charge equals 43.2 x 0.42, which equals 18.14 kg.

To comply with the standard, the VRF/ VRV system should have a charge less than this, or a refrigerant leakdetection system with safety alarms QLAV 3 should be installed. (kg/m ) At this juncture, I must highlight 0.50 the much lower RCL/QLMV/QLAV 0.58 values for R-32 and HFO R-1234ze.

0.42 In other words, split or future VRF 0.15 systems using these refrigerants 0.15 would result in a much lower maximum charge limit.

detection devices should be designed into the system or building. Further details on when each appropriate measure should be applied is given in the standard.

To elaborate by way of an example, let’s consider a VRF/VRV system charged with R-410a (an A1 refrigerant). The system is deployed in a hotel with bedroom sizes of 6m x 3m x 2.4m. The total room volume is 43.2 m3. For a hotel room above ground with a VRF system, the QLMV/QLAV values in Table 1 apply. If the total refrigerant charge exceeds these limits, then a leak-detection

ASHRAE 15 Typically, purpose-built machine rooms for compressor systems or water-cooled chillers contain the largest volumes of refrigerant, either in the liquid receivers, condensers or evaporators. For example, a large centrifugal water chiller used for District Cooling could contain up to 1500 kg of refrigerant gas.

Refrigerants are generally denser than air,

except ammonia, so if a leak were to occur the gas would concentrate on the floor rather than move upwards. Synthetic refrigerants have no smell, so the user would only know that there has been a leak if the chiller starts to lose its performance. As the refrigerant displaces the air, anyone working at the chiller would be at risk of asphyxiation. To lower this risk, ASHRAE 15, the EPA and many local building codes state the following: Each machinery room should contain a detector located at a point, where a refrigerant leak would concentrate. The detector should also trigger an audible and visual alarm both inside and outside the mechanical room and activate mechanical ventilation by way of remedying the situation and ensuring the safety of personnel.

Unravelling the upsurge in the insulation market Insulation is significant for better IAQ and energy efficiency. What role do innovation and overall perception assume, as the insulation market steers towards growth?

By Ranjana Konatt

I

nsulation plays a significant role not only in maintaining the temperature of a room but also in energy efficiency and Indoor Air Quality (IAQ). Industry representatives suggest that the growth of the insulation market is dependent on a number of factors.

Kishore Deotarase, General Manager, Unigulf, estimates the insulation industry in the United Arab Emirates to be approximately AED 300 billion. “Owing to the growth in demand for projects in the United Arab Emirates, the market is likely to grow by 15% in the next few years,” he says.

Echoing Deotarase is Umesh Unni, Regional Commercial Manager, Hira Industries. He insists that Saudi Arabia and Dubai are two major places seeing an increase in growth, as there are projects sprouting in these regions. Elaborating, he says, “Considering the Expo 2020, the UAE will most likely have a higher growth percentage in the years to come.” He estimates a hike in the growth of the insulation market by 15% to 25%, in this year alone. Unni adds that Abu Dhabi is dynamically slower, but not far behind, when compared to the other Emirates.

Ajit S Abraham, Directory Manager, Leminar Global, offers a different opinion, highlighting that projects have not increased, but the number of players in the market has. “The market is seeing the entry of new polymers and insulation solutions, with closed cell insulation and

From traditional to advanced solutions

An evident trend, Unni says, involves seeing manufacturers and end-users move from traditional insulation solutions to more advanced options. “Advanced solutions, such as closed-foam insulation, not only meet the need for long-term energy efficiency but also help to save on costs in the long run,” he says.

And today, he says, end-user preferences are steered towards energy efficiency and durability. Deotarase reveals there is a lack of awareness in the way end-users understand insulation solutions. He says, “An end-user's understanding of insulation solutions is limited to the brand; however, insulation as a subject can get technical.” Even though the consultant might be able to influence the end-user’s choice of insulation, he says, the final decision still lies with the end-user.

Echoing Deotarase is Tomasz Kulik, Global Technical Manager, Hira Industries. He says, “Especially when it comes to technical aspects like condensation, anti-condensation, the level of insulation-thickness as per requirement, they are all important factors.”

Hence, he says that awareness and education are of the essence, if consumers are to save time, energy and money.

Stressing on the need for insulation solutions to adhere to the UAE Fire and Life Safety Codes, Sarmad Fakhri, Managing

Director, Kingspan Insulation, says, “There is an emphasis on fire testing and approval for insulation solutions, and we see this through the increase in awareness for stringent fire testing and results.” Elaborating on the Fire and Life Safety Codes, he says that Chapter 10 of the Fire Code: Smoke Control Systems, addresses HVAC systems and must be considered when choosing insulation solutions. Making a call for awareness, Fakhri says that there is a lack of drive to work towards energy efficiency. He says, “As long as energy bills are low and, as in most cases, the tenants pay the DEWA bills, there exists no real incentive for building owners to look at energy-efficient solutions, such as pre-insulated ductwork.”

Tomasz Kulik

Innovation and contribution to HVAC “The latest is pre-insulated ductwork,” says Fakhri, while highlighting the latest in insulation technology. “Ductwork has traditionally been constructed using galvanised sheet steel with insulation and is usually installed as a separate activity; however, pre-insulated ductwork has integral insulation, which ensures minimum thermal bridging,” he explains. The solution, he says, has low levels of air leakage and, when fabricated correctly, it runs more efficiently while also conserving energy. Elaborating on the benefits of pre-insulated ductwork, he says, “It is extremely lightweight, weighing as little as 18% of the equivalent of galvanised sheet steel ductwork and its lightweight nature means that several sections can be joined together at the floor level before being installed.” A side benefit, he adds, is that it is particularly well-suited to projects where space and structural loading is an issue, for instance, projects with long-spanning roofs, such as airports and malls.

Using non-fibrous, closed-cell materials has IAQ benefits, highlights Fakhri. “A nonfibrous rigid insulation core, minuses the risk of loose fibres entering the air stream through the ductwork,” he says. Since

Umesh Unni distributed air does not come into contact with the insulation material that produces loose fibres, he says, the built-in antimicrobial protection negates the risk of bacterial growth on the ductwork system.

Energy efficiency and insulation Energy efficiency in insulation refers to avoiding energy loss, says Abraham. “The level of thickness used in an insulation solution is crucial and differs for internal and external pipework. For internal pipework the thickness should ideally be 19mm and 25mm for external pipework,” says Abraham. Using reflective material, like jackets, helps, he says, and, when coupled with the right thickness, prevents gaps between the insulation.

“Low ductwork air-leakage can yield significant electrical consumption and savings,” says Fakhri. Pre-insulated ductwork, he says, can have a fraction of air leakage rate, offering energy efficiency and cutting operational carbon dioxide (CO2) emissions, he adds. This, he says, can also reduce the overall energy used to operate the building.

Governments today are talking of setting targets to reduce emissions, in order to tackle climate change, he says. Dubai’s Integrated Energy Strategy and Abu Dhabi’s Vision 2030 are all examples of such steps.

Even though new technology and innovation might be available, the level of acceptance in some cases is slow, highlights Kulik. He says, “Some companies are very adventurous and like to try out new technology, while others take time and prefer to stick to old methods.” Innovation, he says, has played a significant role in contributing to energy efficiency; however, education must, at all times, take the front seat. “If we are to make an impact, we must be welcoming to new technology and insulation solutions, he says.

Highlighting another challenge, Abraham points to insulating large facilities, as yet another area where compromises are made.

“Condensation is a huge problem," he says.

"If you notice, a number of new buildings, nowadays, have droplets coming in, and this is because the thickness of the insulation material has been compromised upon.” This is done to save on initial costs, but such compromises, Abraham adds, can have an effect on IAQ. “The end-user will have to bear the brunt of such mistakes by paying for maintenance and repair," he says. "It is important that zero fire rated products are used, which undergo both factory and thirdparty testing.”

Echoing Abraham, Unni reiterates that cost has always played a major role when a client makes a decision. He says this also meant that energy efficiency often used to be compromised on. However, Unni says, “Today, local manufacturers offer insulation solutions, which are premium in quality and are reasonably priced, hence there arises no need for a compromise.”

‘An attractive

Sliding Up the chord

he Sultanate of Oman has been on a steady path towards economic diversification, effectively pushing a number of industries into the spotlight. Shaikh Raid Bin Abdullah Al Araimi, Vice Chairman, Al Raid Group, an Oman-based developer, cites tourism, light industries, fisheries, agriculture and mining as key sectors in the government’s focus.

As a result, Al Araimi says, these sectors are witnessing an inflow of foreign direct and indirect investments, which can be attributed to a number of factors, namely, “Oman’s political stability and business environment, flexible laws and regulations and state-of-the-art port services and logistics that make it an attractive investment destination of global standards”.

Geeju Paul, General Manager – Air Conditioning Division, Muscat Electronics, holds a similar view with regard to tourism, citing it as a segment where the company has also seen strong growth. Additionally, Paul says, the investment in retail segment is expanding, with a number of luxury shopping malls cropping up. Al Araimi provides Al Raid’s Al Araimi Walk, as an example. Scheduled to be completed in 2020, Al Araimi Walk sits on 140,000 square metres of leasing space and is set to host a number of restaurants, retail stores and entertainment facilities. Its strategic location, Al Arami says, allows it to remain accessible to people from Batinah region, as well from interior regions of Oman. The company shares a projected footfall of 10 million.

In addition to an expanding retail sector, Ahmed Al-Mazrouy, CEO, Al Majis Industries, says that there has been a noticeable uptake in real estate projects at major cities, such as Muscat, Salalah and Sohar. Claudia Massei, CEO, Siemens Oman, weighs in, saying, aside from hotels, shopping malls and industrial facilities, the healthcare sector is booming. Paul seconds this, saying there are a growing number of private hospitals in the pipeline.

In view of such trends, Paul says that projects are steadily picking up in the Sultanate, describing the contracting and tenders segment within the country to be at a “stable scenario”. This spells good news for the HVACR sector, Paul stresses, as relevant products towards the end of projects, are “sliding up the chord”.

Al Araimi, in discussing HVACR requirements of recent and upcoming projects, says the company recognises the importance of proper cooling and ventilation systems for the comfort and satisfaction of customers, especially in view of the luxury developments under its portfolio. “Ideally, the temperature must be 22.5 degrees C, with a minimum of fresh air [changes] of 18%,” he says. “However, anything under 100% is always ideal with dispersed fragrant spritzers to distribute and refresh senses.

Apart from these, energy-efficient HVAC systems are extremely important. The best of water-cooling systems that use centrifugal technology and environmentally-friendly refrigerants must be chosen, as well.”

Currently, the developer is working closely with the District Cooling company, Tabreed Oman, for its projects, particularly with regard to Al Araimi Walk. Al Araimi says that water-cooled chiller systems for the project were developed in partnership with Tabreed Oman, who will also make the capital investment, undertake the implementation and manage operations for a two-year period. “A District Cooling company always provides 24-hour maintenance service, with highly specialised teams, stocks and spare parts, to minimise its initial investment,” he says. “This will ensure cooling services are provided year-round without disruptions. Furthermore, an HVAC package will be tendered and a capable, experienced contractor will be selected at a later stage to implement the design intents.”

While comfort and reliability are vital, especially in the move to be a

investment destination of global standards’

The Sultanate of Oman is taking on a more proactive role managing supply and demand of energy, all while cultivating new industries in an effort to promote economic diversity. What trends among HVACR consumers have emerged as a result? Hannah Jo Uy has the story…

hub for luxury projects, energy efficiency is also emerging as a strong requirement among consumers. Paul says this is a natural reaction following the withdrawal of government subsidies in both private and commercial segments.

Dr Floris Hendrikus Schulze, Managing Director and Head, CESI Middle East, says there has been a reduction in electricity demand in 2017 over the predicted development, as a result. “The sector is seeing a reduced demand from customers subject to Cost Reflective Tariffs (CRT) pricing scheme, where the actual costs now support investments in energy efficiency,” he says. Dr Schulze says that in residential developments, new, energy-efficient “white goods” and efficient lightning solutions are also curbing demand growth.

The commitment to curb energy demand was especially felt, following the Oman government’s announcement that it will implement GSO 2530:2016 on ‘Energy Labelling and Energy Performance Requirements for Air Conditioners’ by November. Oman’s 11.5 minimum energy performance standards puts the country one step behind Saudi Arabia, which has moved to MEPS 3 at 11.8, and on the same level as Bahrain.

Paul says that while initial compliance with new regulations may result in consumers having to pay 30% more, having to opt for newer and more energy-efficient products, eventually the price gap will reduce as manufacturers get into mass production.

“As we have seen before in how the price [difference] between inverter and conventional split units used to be higher, but now the difference is very small, it’s only a matter of time,” he says. “The market has to switch to a new series, and as the volume goes up, the prices will stabilise.” Paul adds that, overall, there has been growing consciousness among people towards more environmentally friendly solutions, as well, with an observable move towards non-HFC or Freon-based refrigerants.

These requirements, Paul adds, makes a case for VRF technology, which continues to enjoy steady growth, gleaning from the company’s observation over the past decade. “The shift is happening from the split side and from the chillers side,” he says, “Customers

using chillers in medium-sized projects are shifting to VRF systems.” Similarly, Paul says, projects that traditionally use split ACs have also opted for VRF technology, because the number of outdoor units is significantly reduced.

Massei adds that with a lot of projects concentrated in and around the economic free zone area, there is a steady demand for other solutions related to building envelop as well, as part of the trickledown effect.

Looking at trends going forward, gleaning from Siemens’ long presence in the Oman market, Massei shares that there has been increasing demand for fire and safety systems, especially following the emergence of new regulations. “Every single building needs fire and life-safety systems, which may not have been true 10 or 15 years ago,” she says. “[Demand for] security systems as well, is growing a little bit. In the hospitality sector, some buildings are starting to install BMS. In general, there is a trend towards increasing the level of technology within a building.”

The demand for greater automation and controls may also be attributed to the subsidy withdrawals, which has prompted stakeholders not only to choose more energy-efficient equipment but also to optimise its usage within the building.

“There were definitely some concerns because electricity subsidies were being cut off,” Massei admits, “so any savings would be going back to the people’s pockets.” She says, however, the move towards greater automation has also been exhibited by those unaffected by subsidy withdrawals, specifically government buildings, which are responsible for heavy usage on the national energy grid. “They conducted an audit for a lot of buildings and found that often air conditioning and lights were left on during the weekend,” she says. “So, they have undertaken several actions to try to [minimise] energy waste.”

The need for automation and better controls could also be attributed to growing recognition of LEED certification across the Sultanate. Massei points to the Oman Convention and Exhibition Centre as an example as being a LEED-platinum project, where Siemens provided the BMS, stressing that it features 5,000 data points to ensure the temperature is constant and there are no deviations. “They have environmental standards they want to comply with, and that makes them more technologically driven,” she says.

Al-Mazrouy says that he is pleased to note a number of projects in Oman certified under LEED, showcasing the stakeholders’ growing appreciation of its importance.

“Green Buildings [are becoming] a necessity in Oman and some Green specifications are already in the present building code,” he says. “Such specifications include insulated roof, land scrapping, reflector light painting and double glassing.” He stresses that it is important for people to realise the value of change, advocating for more pilot projects demonstrating stakeholder benefits. “For example, the immediate and direct benefit from Green Buildings is the reduction in electricity and water consumption and also reduction in the cost of building materials.

These reductions will be visible to the bill payers and subsidy provider.”

Al Mazrouy adds that there is still more to be done in changing the consumer culture.

“Change is difficult and requires continuous dialogue and networking, using all available media to spread the message,” he says. For their part, Al Mazrouy says, Majis Industrial Services has taken a number of initiatives on electricity demand-side management, including replacing conventional lighting to energy-efficient type (LED), adding that the company is also working to have an energy mix for water solutions, and is aiming at least 20% of energy consumption from renewables by the end of 2020.

“However, the tariff of renewables must be commercially viable for the company,” he stresses.

Supply side: The progress of renewables This falls in line with Oman’s move to set renewable targets in the power generation mix. Dr Schulze adds that the most imminent development is for the contracting of grid-connected PV in the coming years, in tranches of 500 MW each. “The development of the renewable energy potential from Oman’s vast wind resources will require an interconnection from the Dhofar region to the main interconnected system,” he says adding that PDO and Shell development are actively supporting renewable energy projects in solar PV. Dr Schulze says that CESI Middle East has been, and continues to be, involved in supporting several utilities in Oman, and the Regulator of Oman in setting up rules for a safe and adequate integration of small-scale and larger-scale renewables into the grid. “This includes rooftop solar and hybrid systems in which diesel generation is combined with solar,” he says. The company,

he says, is also supporting Shell in rolling out the Nationwide Solar into Schools programme, a project involving the use of solar power for domestic consumption in public schools.

Dr Schulze says CESI is also supporting Nama Group Oman with its Automated Meter Reading (AMR) technology implementation project, which is closely monitored by the Authority for Electricity Regulation, and serves local distribution companies, such as Muscat Electricity Distribution Company (MEDC), Mazoon Electricity Company (MZEC), Majan Electricity Company (MJEC), Rural Areas Electricity Company (RAECO) and Dhofar Power Company (DPC). “With a goal of enhancing the quality and speed of processing metering data, this AMR rollout will work towards improving billing accuracy, mitigating losses, lessening query related costs and reducing debtor days,” he says.

Other interesting projects of note in Oman, Dr Schulze says, include the interconnection between the north and south of Oman and support for several distribution companies in the reduction technical and commercial losses. “The company is also heavily involved in technical and commercial feasibility projects to connect the GCC interconnected grid to neighbouring regions, which will boost and support the trade and exchange of energy,” he says. Dr Schulze says industrial consumers have expressed interest in their own solar PV deployments, as a business case, lowering the electricity cost and are considering entering into a new source of income by generating green energy, which in the future, may be exported through interconnected links to neighbouring countries and regions.

Al-Mazrouy says that while there are a number of successful initiatives, the market remains relatively conservative. “One of the deceleration factors is cost of renewable in comparison to conventional,” he says.

“Majis is working on a renewable initiative of 1.3MWhr and soon will float the tender.

The bidders will be limited to those who are approved by the distribution companies via Distribution Code Review Panel (DCRP).”

As the country continues in its move towards economic diversification, new trends continue to emerge as the Sultanate looks towards a future free from dependence on oil.

to improve indoor air quality. Do regular inspection and testing for gases, particles and microbiological organisms, and take immediate actions to rectify the problems, if any. Provide local hooding with exhaust for bathrooms and kitchen. Routine monitoring of various parameters of HVAC systems, proper maintenance of all parts of the system and regular inspection and cleaning of air conditioning ducts are some of the airborne infection control techniques. Examination of floor and wall surfaces for cleanability, regular ‘deep clean’ after infectious patients leave the site, measurement of air quality periodically and regular microbiological testing are some of the routine monitoring strategies for infection control.

Involvement of hospital infection control team Effective functioning of an infection control committee in a hospital – in which a pathologist, infection control officer, head of nursing affairs, representative from the surgery department and hospital engineer are the members – is very crucial to monitor IAQ in healthcare institutions. The infection control team of the healthcare unit is to be involved at all stages of the hospital's construction, from pre-design through to opening, and adequate time for commissioning should be built into the schedule, including an allowance of time for microbiological assessments, particularly in hospital operation theatres. Commissioning is a task for both the engineering department and the infection control team, and cooperation and coordination between them is important. The infection control committee has to review the surveillance data routinely in order to identify/detect problems with regard to inherent potentials for unusual epidemics, clusters of infections, infections due to unusual pathogens or any occurrence of nosocomial infection that exceeds baseline levels, and also to ensure strict compliance by all departments with the hospital’s infection control policies and procedures.

• Use of eco-friendly cleaning products – encourage the housekeeping and cleaning unit of the hospital to use eco-friendly cleaning products, as industrial cleaners can leave residue that will affect air quality badly.

Conclusion A healthy solution should be achieved if good standards of design, commissioning, operation and maintenance are followed and proper functioning of the infection control department of a hospital is ensured.

A common strategy to maintain a proper IAQ in healthcare units is required. The strategies, once ready, can be enforced through local government regulations. The strategies should include various codes, practices, documents, procedures and commissioning formats.

Awareness among healthcare service staff Create awareness among the staff and public about the importance of IAQ and encourage them to observe the following: • Do not bring non-sterile objects into the room – particularly in designated clean areas.

• Do not open windows unnecessarily – frequent opening of windows allows external pollutants in.

• Change prescribed clothes before entering into the clean areas and wash hands after touching infectious items.

• Do not allow too many visitors around patients.

A few easy tips to improve IAQ • Ventilate – airflow is crucial for good indoor air quality.

Use proper ventilation requirements, as per the healthcare standards.

• Keep HVAC system spotless – it is critical to regularly clean filters according to the manufacturer's instructions.

• Use of activated charcoal – activated charcoal reduces air contaminants. It is present in many HEPA filters used in HVAC systems.

• Plant houseplants – some houseplants can help to remove toxins from the air, whilst providing additional oxygen.

Identify such plants and keep them at appropriate locations in the hospital.

of maintaining the cooling tower with least power consumption and preserving water. We have our own maintenance team, and we can certainly help in this regard.”

Weighing in, Talal Damerchi, General Manager, Hamon Cooling Tower Company, said that the answer may lie in a more collaborative approach involving all stakeholders: “Manufacturers’ councils exist in many countries, where manufactures provide an integrated approach to resolve issues and work with regulators to provide input on pending legislation,” he said, “We would also welcome and support a more collaborative approach between manufacturers and Facility Management (FM) companies so that we both share in the best way to maintain the equipment. That is not happening, currently, to the degree we would like.”

Damerchi said that the company believes FM companies can be a good ally in providing value-added services to building owners. “The FM companies have a much larger scope than the manufacturer in the maintenance and operation of the plant,” he said, “and it will be to everyone’s benefit if the FM companies started to cooperate with the manufacturers on the best way to maintain the equipment.”

Damerchi added that the company is very active in providing aftermarket solutions and is now cooperating with Dubai South to upgrade the plants, which have Hamon cooling towers. “We have also worked with Empower on the upgrade of the Palm and JLT plants,” he said. “We are currently bidding on

several upgrades for plants, and we intend to expand in the maintenance and repairs, upgrade, spare parts and maintenance contracts as we are fully capable of performing these services because of our presence in the country and [by virtue of] having our own team here.”

Sankary stressed that upgrades should not be confused with replacement. “Replacement typically means replacing parts as much as

possible,” he said. “Upgrade, on the other hand, involves not only replacing parts with a better, more efficient component; it goes much deeper into analysing the requirement of the plant currently versus the original requirement and to study the performance of the existing cooling tower to establish if it meets the current requirements of efficiency, environment, water consumption, water quality, water source, etc.” Sankary said that

the company’s strategic offering is due to efforts to navigate the price-driven market by offering a value proposition. “We are not just going to maintain it as it is, we try to make improvements, so their operating cost would go down. By using this approach, we hope we can become a partner rather than just a supplier.”

Al Nimer said that the consultant and contractor seminars will focus on the SAC line-up, control system solutions and application, operation management, reference sites, optimisation of DVMS for energy efficiency by design and solutions for sustainable buildings, highlighting low-energy consumption products.

Lastly, Al Nimer said, the vertical-specific training will explore industry-specific trends in hospitality, government and education sectors. The topics covered, he added, include Samsung’s AC

business vision, control system solutions and applications, operational management and sustainable building practices.

Shofil Abdul Rahiman, Manager, B2B, Pre/Post Sales, Samsung Electronics, said that the Academy will publish a calendar of events through a dedicated online portal that allows attendees to access results and receive further invitations. Rahiman said that a major area of focus will be on VRF technology, adding that while the market is now mature enough to see and recognise the benefits of VRF technology, training is needed, especially with regard to installation. The Academy, he said, will facilitate sessions from theory, pre-installation to commissioning of VRF technology, in the move to advance the technical skills and knowledge of distributors.

Al Nimer added that all training sessions are free of charge and that the Academy’s main goal is to cultivate best practices in the industry and share innovations within Samsung. Al Nimer said, the plan is to hold monthly training sessions for the local market and the region, inviting experts from other markets to underpin the Academy’s commitment to be a regional hub, and in line with its commitment to cultivate best practices in the regional market.

Providing an exclusive tour of the facility, Al Nimer highlighted the live systems within the Academy, including control solutions and different applications, ranging from small and medium to big projects. The facility, he said, also includes stations featuring service, commissioning and installation tools and has a capacity of 30-35 people per class. Rahiman also highlighted the custom-designed simulation kits, developed especially for the training programme, which mimic the electronic parts of an air conditioner. Rahiman added that it allows trainees to familiarise themselves with the controllers and gain confidence that they are able to handle the machine, once it arrives on site.

Al Nimer said this is especially useful for new engineers who are apprehensive about managing equipment, such as VRF equipment, as the outdoor and indoor simulation kits allows them to practice. Al Nimer said the Academy will also launch an education campaign, and will look to invite engineers at the university level to the Academy, so that they can benefit from the live system facilities and hands-on training sessions.

urovent Middle East discussed the inroads VRF technology is making in the market, during the latest installment of its ‘HVACR Leadership Workshop’ series, on September 19, in Dubai. During the opening address, Markus Lattner, Director, Eurovent Middle East, spoke about the association’s recent milestones, and its profile of activities as a voice for manufacturers “for the region, out of the region and in the region”. Lattner outlined the agenda of the seminar, which featured presentations from multiple stakeholders on key issues regarding VRF technology.

Omar Dawood, Technical Sales Manager- System Air Conditioners, Samsung Gulf Electronics, kicked off the seminar with a comprehensive presentation on the benefits of VRF technology and the need for better performing equipment following consumer demand for energy-efficient solutions.

Dawood spoke on the merits of VRF technology, with regard to addressing temperature fluctuations and its architectural benefits, and highlighted how the system offers itself as a modular equipment solution. Dawood stressed that increasing awareness of global warming and the need for environmental protection

have paved the way for the technology in the region.

Dr Asit Kumar Dutta, Manager, Technical and Engineering Department, Fujitsu General (Middle East), delved deep into VRF specifications in the move to unravel the misperceptions associated with the technology. Dr Dutta touched on issues related to key components, such as the compressor, expansion valve, fat motors and the printed circuit board (PCB). Dr Dutta also highlighted the main criterion driving the selection of VRF technology, such as energy efficiency, installation freedom, ease of transportation, availability of software and user-friendly controls. Dr Dutta concluded his session by highlighting how preventive maintenance can increase the longevity and extend the lifetime of the unit up to 15 years. Proper tuning of the main parts can also determine best cooling performance, he added.

Bibin Thomas, Business Development Manager, Adel Electronics, spoke on how VRF installers can add value to the overall operation and efficiency of the technology, providing audiences with a step-by-step overview of the installation process and best practice in this regard. Thomas provided a number of installation recommendations, in relation to testing and commissioning

reports, alternative piping and insulation materials. Thomas stressed that demand for qualified installation professionals is growing, citing the 17% increase in VRF jobs between 2015 and 2017 as an example of the gap in the market. He emphasised that skilled installers play a vital role in optimising product performance.

Michel Farah, Vice-Chairman, Eurovent Middle East, Director – Corporate Environmental and Social Responsibility, Daikin Middle East and Africa, provided a comprehensive overview of VRF regulatory requirements in the GCC region, in a move to provide attendees with greater clarity on the different parameters being specified by respective authorities. In discussing current regulation and labels of countries in the region, Farah emphasised the burden of cost placed on manufacturers that look to enter new markets, driven by the need to comply with the spectrum of labels and regulations.

This, he said, is why Eurovent supports efforts to unify regulations in the GCC region. Farah also spoke on how MEPS regulations and labelling programmes help shift the market towards higher efficiencies, why revisions of GCC regulation need to involve stakeholders to be efficient and how air conditioning variable speed trends can play an important role in achieving energy efficiency and carbon reduction targets. Farah also called for a gradual move from EER to SEER for T3 conditions, to demonstrate the real yearround energy efficiency and savings.

Dharmesh Sawant, Senior Manager, LG Electronics, spoke on the feasibility of VRF in residential applications, urging stakeholders to look beyond capital cost and take into account other factors that offer long-term gains. He presented a case study of a luxury villa to highlight how VRF technology was able to address client requirements, including compliance with Green Building guidelines, system longevity and latent load control, especially as the villa, being close to the sea, suffers from humidity and reduced electricity consumption. Sawant also highlighted the considerable opex savings the technology offers, the importance of redundancy, in the event there is a failure in a module, as well online remote monitoring features, in order to reduce service downtime.

To conclude the event, Midea provided an overview of numbers and figures related to the uptake of VRF technology in the context of the global HVACR market and made a case on how the product can be optimised as a retrofit solution to address inefficiencies in existing building stock.

raining lies at the heart of every strong FM solutions provider, and Mahmood Hussain Rasheed, COO, Imdaad, said the company has invested heavily in this regard, especially when it comes to adding specialised HVACR FM solutions to the company’s expanding portfolio. “We have allocated a separate budget for our training department,” Mahmood Hussain Rasheed Rasheed said, “because if our technicians are trained, and they know how to handle the problem, especially with the ACs, the pumps, [and similar equipment] we can repair whatever is at fault from the first visit. But if they are not trained, our cost will be higher, as we will keep coming back for the second time, the third time, etc.”

Avoiding the long-term inefficiency that comes with inadequate training is a strong driving force behind Imdaad’s investment, Rasheed said, stressing that in addition to basic and theoretical courses, personnel are made to undergo hands-on training sessions. “We have a small room, with all equipment where we see how they fix and repair the AC unit or the pump, so when they go to the site, they will not be surprised. Some of the technicians you bring from overseas, the first time they see certain equipment, they would be surprised. They may know the theory, but once they have to physically handle it, what would require only 10 minutes will take one hour.” Rasheed said this is why Imdaad simulates a real-world environment that will allow technicians to be ready once on the field. “Yes, we may be spending a little bit more on the training,” he admitted, “but we are saving on time, [reducing] the calls, and saving on the repair. This is the payback of investing in training. It may be intangible at first, but in the long-run, it will be tangible.”

Rasheed said that while the market has matured over the years, showing greater appreciation for the role FM solutions play in optimising building operations, cost remains an issue, with clients demanding more, yet often reluctant to pay for higher quality services.

Communication gaps can lead to inefficiencies in the construction industry Stakeholders stress the value of involving Facilities Management companies in the design stage of a building

By Hannah Jo Uy | Assistant Editor

F

acilities Management (FM) providers play a vital role in optimising building operations, yet as they enter a development after hand-over, there often is a communication gap between the stakeholders, who design and install the equipment in a building, and those who inherit and operate it.

The gap can lead to inefficiencies, especially when it comes to equipment that requires technical knowledge, such as those in the field of HVACR. This was the perspective Saad Ali, General Manager (Middle East and Africa), SPX Cooling Technologies, which specialises in cooling towers, shared, stressing that not all FM companies are equal, especially when it comes to cultivating the necessary skill and technical knowledge for specialised products.

"There are good companies that work well and come to manufacturers to ask how they can improve the systems and meet performance standards," he said.

"However, some FM companies accept projects without looking carefully at the product portfolio to be managed and what they are skilled at handling. It's a recipe for disaster and can get them in trouble."

Ali added that there have been instances, where the facility manager approaches the company and buys parts to rectify certain performance issues in order to meet the responsibilities. "But that's backward," he said. "You build something new; you discover it's not doing the right job. I can't blame the FM company. They should have the capability to assess the facility before they accept the project." Ali stressed that FM managers should be given the opportunity to review

facility equipment lists and performance reports in advance before accepting the documents of a newly constructed building.

Darren Farrell, Regional Sales Director, ME, Africa and ASEAN, Greenheck, which manufactures air movement, air conditioning and air control equipment, spoke on the value of involving FM companies even sooner, by highlighting the financial payback of a collaborative approach from the very beginning. “It’s all going to come down to the cost of the building,” he said. “If something is installed incorrectly and FM come in and do their measurements and redo the piping, for example, that’s a huge cost.

If they’re involved sooner, you can check and ensure it doesn’t happen, which will have potential cost implications.” Farrell added that FM companies can share key insights based on their experience in operating buildings, which could be especially valuable in conjunction with third-party bodies, which he believes should be involved in stricter guidelines and practices to provide a level playing field. “As a manufacturer, who abides by all the rules and ethical practices, it’s difficult for us to compete in markets, where that is not there,” he said. “As for FM’s role maybe, by law, the building has to be passed by FM, as well. That is, for us, the ideal situation.”

Providing an FM company’s perspective, Mahmood Rasheed, Chief Operating Officer, Imdaad, echoed the value of a collaborative approach.

“There is always a conflict between the commercial needs of the client and the operational needs of the facility end-

user,” he said. “To ensure value for money, the project or construction team must clearly define the needs of the client and end-user for optimum balance. This is possible by connecting all involved parties and bridging the gap in the design stage itself. The involvement of FM companies in the design stage will eliminate unnecessary expenditure for any design modifications or alterations at a later stage and maximise the performance of facilities.” FM companies, Rasheed said, eventually have to respond to the needs of the end-user, and thus, their initial involvement in any project will make it easy to run, maintain, control and manage.

Rasheed said emerging technologies, such as Building Information Modelling (BIM) and Additive Manufacturing, will further underpin the importance of a collaborative approach. Citing an example of the Dubai government's move to improve productivity by mandating the use of BIM in construction projects of more than 20 floors, as well as those with areas larger than 200,000 square feet, Rasheed also pointed to plans of using 3D-printing to build a skyscraper. “We believe this technology is a harbinger of a new future for the FM industry,” he said. “BIM and 3D-printing, along with additional building construction innovations in laser scanning, drone technology and machine control, all have the potential to boost construction productivity.” Ultimately, Rasheed said, integrating FM providers into the project team at the beginning of the process can be seen as a safety mechanism to eliminate the emergence of problems at a later stage.

SASO Standard 2874 adopts AHRI standards for all applicable products

Exclusive “Path A” compliance for AHRI-certified manufacturers established, AHRI official says

By Hannah Jo Uy | Assistant Editor

ir-Conditioning, Heating, and Refrigeration Institute (AHRI) has closely collaborated with Saudi Standards, Metrology and Quality Organization (SASO) in the development and implementation of SASO Standard 2874 (Air Henry Hwong Conditioners – Minimum Energy Performance Requirements and Testing Requirements), said Henry Hwong, Senior Vice President, Standards and Global Operations, (AHRI).

Speaking on Saudi Arabia’s updated regulations and level of collaboration between the two bodies, Hwong said Standard 2874 not only adopted AHRI standards for all applicable products but also established an exclusive “Path A” compliance for all manufacturers that are AHRI-certified. “AHRI worked closely with SASO to demonstrate the stringency and the applicability of its certification programs to establish the

exclusive path, which allowed AHRI-certified manufacturers to register and meet compliance without having to submit test reports for each model,” he said. “In addition, for configured applied products, such as chillers, AHRI worked with SASO to establish an exclusive web portal, whereby AHRI-certified manufacturers can provide validation of performance to SASO directly.”

Hwong said AHRI, in recognising the importance of providing tested and certified performance data in real time, has made significant investments to provide the data, developing the necessary IT infrastructure, so that portals, “such as what was provided to SASO at no cost can be provided to other regulatory bodies also”. As a non-profit industry association, Hwong said, AHRI’s goal is to provide industry services that will facilitate global trade, while ensuring the integrity of the market place and a level playing field for competition.

ENGIE Refrigeration makes waste heat usable

Company’s air-cooled Quantum chillers also available with heat recovery features, official says

NGIE Refrigeration has announced that its air-cooled Quantum chillers can now be equipped with heat recovery as well, in a Press communiqué. This makes it possible to reuse up to 100% of the generated waste heat, the communiqué said. In July 2018, the first air-cooled Quantum chiller with heat recovery was put into operation in France, at an international industrial plant, the communiqué further said.

According to ENGIE, for many years, the company has been equipping its watercooled Quantum chillers with heat recovery as an option. Many Quantum chillers with heat recovery are successfully operating around the world, the communiqué said.

Now ENGIE is making this option available for air-cooled Quantum chillers, as well, the communiqué further said.

According to ENGIE, a heat exchanger integrated in the air-cooled Quantum chiller,

as an addition, makes it possible to conduct the heat, which is generated during the cold generation process, to a defined heat process, such as heating or the warm water supply. That means an air-cooled Quantum with a refrigeration capacity of 1,300 kilowatts can create a heat capacity of

1,480 kilowatts, the communiqué said.

The heat generated during the refrigeration process can be used either completely, or partially, in what is referred to as mixed mode, the communiqué said. To this end, the waste heat is transferred to a heat circuit via a parallel flooded shell and tube condenser, the communiqué further said.

As the chiller fans are now running at partial load or not at all, this makes it possible to save power and money, the communiqué added. At the same time, users take advantage of the thermal energy that is generated and, as a result, heat recovery is not just sustainable but also conserves resources, the communiqué further added.

According to ENGIE, integrated heat recovery in an air-cooled Quantum chiller is highly suitable for all industries that can utilise waste heat, such as production plants, hospitals and hotels.

Masahiro Tsujimoto, Managing Director, Ziehl-Abegg Japan, said, during an international conference in the German Fan Valley. “We must be able to reduce the big energy consumption of cooling machines in Japan and reduce the noise of these machines,” he added.

“The requirements changed during the past 100 years,” Tsujimoto said. “In the beginning, the focus was on the life period, later on the ventilation system performance. The energy consumption has been important for roughly 20 years. Furthermore, people evaluate noise as pollution of the environment or as noise disturbance in the past few years.”

Tsujimoto explained: “There are two possibilities – the planning of new buildings and the refurbishment of existing buildings. The ventilation system of old buildings is often too noisy and consumes too much energy.

he use of CFCs in refrigerants was the topic of discussion for a prolonged period of time, until their ban, following the agreement of the Montreal Protocol. However, the Environmental Investigation Agency (EIA) recently released an investigative report, entitled ‘Blowing it: Illegal Production and Use of Banned CFC-11 in China’s Foam Blowing Industry’, revealed Julian Newman, Campaigns Director, Environmental Investigation Agency (EIA).

Julian Newman Elaborating on the investigation, Newman said, EIA has been investigating and exposing illegal trade in ozone-depleting substances, such as CFCs, since the late 1990s. He said: “Our expertise lies in understanding illegal trade routes and smuggling methods. It appeared to us that the problem of illegal trade in CFCs had diminished from a peak of 38,000 tonnes a year, in the late 1990s, to the global phase-out of CFC production in 2010.” It came as a surprise, he said, when a scientific paper, released in May 2018, revealed a mysterious rise in CFC-11 emission into the atmosphere, which he insisted, should have not been the case, if the Montreal Protocol (the United Nations agreement on tackling substances that deplete the ozone layer) had been complied with.

Newman said, “The scientific paper suggested that the rise in emissions was due to a new and unauthorised production of CFC-11 somewhere in East Asia.” Based on these findings, he said, the EIA sought to verify the scientific findings by conducting an investigation into the illicit production of CFCs, turning its attention to China, as it was the world’s largest CFC producer at the time, during the phase-out in 2010. He said: “We felt the need for a research to help us pinpoint the cause of the CFC-11 emissions. This, in addition to help assisting the parties to the Montreal Protocol, so that appropriate measures to tackle the problem could be taken.” Adding, Newman pointed out to the need for clear evidence, which was provided by the investigation.

Elaborating on the techniques used to conduct the research, Newman said: “The investigation involved identifying potential target companies, which might have been producing or using the banned CFC-11 substance and, then, contacting them by posing as potential buyers over telephone and e-mail.” The next stage, he said, was to meet the selected target companies, based on the response they provided to the initial approach.

Through this, he said, the EIA obtained a testimony from the representatives from 18 companies in China, who were actively using CFC-11 as a blowing agent to produce PU foams.

Elaborating on the effects of CFC emissions, Newman said that once they rise into the stratosphere, they are broken down by Ultraviolet (UV) radiation, resulting in the release of chlorine atoms. This, he said, destroys the ozone molecules, which make up the Earth’s ozone layer, which can have a disastrous impact on all life forms on Earth.

Offering a remedy to the situation, Newman pointed out to regulation as the ideal solution. He said: “Regulation is vital in protecting the environment, and the Montreal Protocol has been a successful global agreement in terms of phasing out ozone-depleting substances and allowing the ozone to recover.” China, he said, has played a very important role in the success of the Montreal Protocol, and there are indications that the government has already taken steps to tackle the illegal production and use of CFC-11 in the country.

“Support,” Newman said, “is needed for the thousands of small and medium foam manufacturers in China to switch to more environmentally friendly alternatives.”

HVAC industry needs skilled workers

Education and quality training within the HVAC industry is the need of the hour, says EGIA Foundation

By Ranjana Konatt

“I

f you ask just about any contractor of what their biggest pain point is, they’ll tell you that it’s finding good people to hire,” said Erin McCollum, Development Director, EGIA Foundation, while discussing the need for quality training within the HVAC industry.

According to EGIA, 115,000 HVACR workers will Erin McCollum be needed by the year 2022. McCollum said: “Skilled workers in the industry are ageing and retiring at a rapid rate. Not only does the industry need more skilled workers, but it also needs more young people to join the HVAC workforce, who are prepared, passionate and committed to making a positive impact.”

Commenting on the factors influencing the HVAC industry, McCollum said, “The industry is greatly influenced by globalisation, environmental regulation and consumer urgency.” This, she said, is what gives rise to the desire for smart spaces, which use innovative applications of IoT. Stressing the need for a skilled workforce, she added, “The use of technology has made the HVAC industry look smart, and this will definitely lead to an increase in demand for IoT-enabled system communication; however, to deliver on market demand, there will have to be a rise in the number of skilled persons joining the workforce.”

EED v4.1 emphasises on the improvement of IAQ through the impact category health and human experience said Marisa Long, Vice President, Communications, U.S. Green Building Council (USGBC). She added: “Requirements and options within the Environmental Quality (EQ) section, balance the need for prescriptive measures with more performance-oriented credit requirements. Also, low-emitting materials credit is performance-based and measures the actual emissions from the product, instead of only the VOC content.”

While highlighting how LEED v4.1 has been positive in the market, demonstrating leadership, she said, “Buildings today are responsible for an enormous amount of energy use, resource consumption and greenhouse gas emissions, but LEED 4.1 continues to be a cost-effective solution that transforms the builtenvironment.”

Data centres need to go Green, says DigiPlex It is important for data centres to have a strategic, long-term, focus on sustainability, says company’s representative

progressive data centre must do what it can to reduce its environmental footprint, said Geoff Fox, Group Chief Innovation and Engineering Officer, DigiPlex Data Centres, while stressing on the importance of energy efficiency and the need for data centres to go Green. “Data centres today account for two per cent of the world’s annual CO2 emissions and three per cent of its power consumption,” Fox said. “Hence, it is important for data centres to have a strategic long-term focus on sustainability and take up measures to combat global warming,

which can be achieved only through innovation.”

Explaining how DigiPlex decided to run Geoff Fox data centres on clean and renewable energy, Fox said, “The whole grid in Norway runs on renewable energy from hydro sources by harvesting rainwater.” The most effective mechanism, Fox said, is the air-to-air cooling mechanism. The technology, he said, capitalises on the cool atmospheric conditions of the Nordics to deliver efficient cooling.

Describing the role of technology in saving energy, Fox said, “The air-to-air technology enables energy savings of up to 25%, as compared to the industry average, globally.” Highlighting another innovation in the field of intelligence, he said that Concert Control, an application DigiPlex has introduced, uses an algorithm to optimise the performance of the company’s proprietary evaporative cooling system, thus controlling the provisions of the data hall, based on the electrical power consumed by the data servers.

ortum Oslo Varme’s 60-mile thermal energy distribution system and data centre operator, Digiplex will cater to the heating needs of approximately 5,000 apartments, said Geoff Fox, Group Chief Innovation and Engineering Officer, DigiPlex Data Centres. Elaborating on the project, he said: “The energy efficiency factor comes from using modular, series-mounted heat pumps, rather than large cumbersome centralised chillers, hence reducing running costs. In general terms, Fortum will bring the system, piping it into the DigiPlex site, which terminates in a heat exchanger.

After which DigiPlex will provide heat at the prescribed temperature on to the facility side of the heat exchanger.”

Explaining how waste heat re-capture improves data centre efficiency, Fox said, “The benefit comes from capturing high Megawatts (MW) of energy and instead of releasing it into the atmosphere, we will recycle it into a usable form.” Highlighting that the project uses the Indirect Evaporative Cooling (IEC) system, he said, “Special coils are placed in the air plenum where heat in the

exhaust air is captured by cold water running in the coils, lifting the temperature to 68 degrees C, using heat pumps.” However, he mentioned that DigiPlex might introduce a system that recovers waste heat with the help of generators, instead of heat pumps.

Fox also pointed at retrofitting of existing data centres as a good solution to using waste-heat for local district heating.

Elaborating on the subject, he said, “One example is the DigiPlex and Stockholm agreement, where an operational data centre was retrofitted to heat approximately 10,000 residential apartments.”

He said that, in the future, DigiPlex plans to cater to 10% of Stockholm’s heating needs just by creating a synergy between recovered data centre heat and the city’s heating needs. He added: “One of the city of Stockholm’s environmental objectives is to be fossil-fuel free by the year 2040. Using by-product heat is an efficient way of generating heat through data centres, which might encourage end-users to ask for clean and green data centres in the near future.”

Airedale launches new adiabatic cooling solution for data centres Traditional leak-detection systems don’t always work efficiently, making the need for innovation essential, says representative

By Ranjana Konatt

L

eaks are one of the biggest downtime threats for data centre operators, and preventing them is a fundamental area of concern, said Jon Martinez, Commercial Controls Manager, Airedale Air Conditioning. Standard technology and traditional leak-detection methods, he said, often don’t work efficiently, making the need for innovation essential. “There is a need for constant development, where even the slightest difference in volumes of water moving through the various points in a data centre cooling system must not go unnoticed,” he said.

Elaborating on the new Tire 4 Treated Water Distribution System (T4TWDS), Martinez said that the mechanical control

solution monitors and controls water treatment, storage and distribution for adiabatic cooling units in data centres. He said: “The T4TWDS was designed using a complex algorithm of volumetric flow monitoring to detect leaks and faults, while ensuring that a data centre’s cooling system is never disrupted.

The solution can be used across independent control panels, while operating a series of valves, pumps and water treatment plants, where water is taken from the main water supplier, treated, stored and then delivered to adiabatic cooling units in data centre buildings.” The valves and pumps, Martinez said, operate automatically, based on the demand from the cooling units, and the introduction of the anti-vortex device, at various points in the system, eliminates the possibility of air, allowing an increased stability in flow-meter readings.

Martinez highlighted that the data cooling industry is driven by energy efficiency and that there is a rise in demand to reduce its carbon footprint. He said, “Data centres today are becoming more reliant on adiabatic cooling, as a primary cooling medium, and adiabatic cooling systems have functioned as an external back-up to the more traditional cooling system.”

ir conditioning solutions provider, Carel’s new plant in the SND district of Suzhou, China, will help increase the availability of new products, while providing its customers with improved services, said Luciano Marzaro, Managing Director, Carel.

Luciano Marzaro Marzaro said that customers will benefit from shorter lead times, while the availability of locally manufactured products will increase.

“With a goal to continually improve our service, the new plant is in a strategic position, which will be a boon not only to the Chinese HVAC market but also to the Asia-Pacific region,” he said.

Elaborating on the role of the laboratory of the new plant, Marzaro said, “The laboratory will be large enough, not only to carry out testing but also to show customers the real-time benefits during the application of a particular product.” He added that the local research and development department will use innovative technology, and the solutions provided will have high energy-efficiency levels, with respect to sustainability and the environment.

“T

he research comes as a surprise, as it’s been years since we’ve heard of the use of CFC refrigerants by HVAC manufacturers,” said Biagio Lamanna, Manager, Carel HVACR Knowledge Centre, in response to the recent report by the Environmental Investigation Agency (EIA). The report entitled, ‘Blowing it: Illegal production and Biagio Lamanna use of banned CFC-11 in China’s foam blowing industry,’ exposes the illegal production and use of CFCs by select HVAC manufacturers in China, said Julian Newman, Campaigns Director, EIA. According to Carel, the company recently announced its upcoming new plant in the SND district of Suzhou, China, and said that it had made a precise decision to discourage the use of CFCs. Further, its range of products is not compatible with the banned substance, Lamanna said. “Our Research and Development department has been focused on new features and solutions that are fully compatible with natural and low-GWP refrigerants. As members of associations that promote the use of natural refrigerants, we are regularly involved in events that support the efficient use of natural refrigerants,” Lamanna added.

Lamanna pointed out that the report meant bad news for the Chinese HVAC market and finding an ideal solution will not be easy. He said, “The findings of the report have been an unexpected development; however, we haven’t been involved with CFC applications for nearly 25 years now, and this means that a lot has been done to prevent the use of CFCs.”

he Chinese Ministry of Finance announced that 5,207 separate tariff lines of the harmonised tariff schedule – amounting to USD 60 billion worth of goods from the United States – would be subject to additional tariffs of 5-10%, in response to the United States Section 301 tariffs on Chinese goods, AHRI said, in a Press communiqué. These tariffs are the final version of the preliminary tariffs announced on August 3, the communiqué said. The Ministry of Finance also announced that China will "respond accordingly" to the United States administration's plans to increase the third round of Section 301 tariffs from 10% to 25% on January 1, 2019, the communiqué further said.

The communiqué said China's retaliatory tariffs affect a variety of goods manufactured by AHRI members, including compressors, refrigerators and freezers, water heaters, boilers, heating equipment, heat exchangers, air conditioners, cooling equipment, control equipment, refrigerants, radiators, fans and vending machines. The communiqué further said that AHRI encourages members to review the original tariff annexes, published by China's Ministry of Commerce, to ensure a complete analysis.

ith refrigerants being emitted into the environment during production processes, due to leakages, as well as during end of life (EOL) disposal of the appliances, measures must be taken to reduce their negative ramifications on the environment.

This was the stance Kevin Bayuk, Senior Financial Fellow, Project Drawdown, shared as he highlighted key takeaways from the Refrigerant Management Technical Report authored by Kapil Narula. With refrigerant management ranked the number one solution in the move to reduce greenhouse gases, Bayuk outlined the five main recommendations to move the dial on the issue: 1) Lowering demand/use of appliances and, thereby, production of refrigerants, 2) Replacing refrigerants with low GWP HFC/new cooling agents/nonHFC substances, 3) Increasing efficiency of refrigeration in appliances, thereby lowering the use of refrigerants, 4) Controlling leakages of refrigerants from existing appliances by good management practices and 5) Ensuring recovery, reclaiming/ recycling and destruction of refrigerants at EOL. Bayuk said Drawdown’s analysis, report and solution models the lasts two options, and discussed some aspects of the second solution, specifically in the context of the recent Kigali accord.

Bayuk said the solution is restricted to refrigeration, heat pumps and air conditioning applications and takes into account CFC, HCFC and HFC gases separately, as these have different GWP and phase-out schedules. “The solution consists of two parts,” he said, “emissions that can be avoided by controlling leakages from refrigerant banks and emissions that are avoided by destroying refrigerants, which are recovered at end of life of the equipment.”

Focusing on the strategies modelled by Project Drawdown, Bayuk said literature suggests that refrigerant management is difficult to implement as the appliances are

distributed. “There are weak regulations on controlling leakage of refrigerants, EOL recovery and destruction of refrigerants,” he said. “Further there are no economic incentives for the recovery of refrigerants.

Funding, training, technical and informational barriers are also some of the limitations for adoption of the solution.”

Kevin Bayuk

Bayuk said in order to increase adoption, policies and regulations on recycling/ management of refrigerants need to be formulated and implemented. “Strong regulations, such as a complete ban on venting of refrigerants and accountability of refrigerants, have to be introduced in national legislation,” he added. “Economic incentives for recovery, recycling and destruction of refrigerants, such as issue of carbon credits under the Kyoto Protocol would help increase the adoption in developing countries.

Capacity building in these countries, including technology transfer, would help aid faster adoption of the solution.”

Informational barriers, Bayuk said, is another bottleneck. “Increased adoption of better practices is needed,” he said. “Service technicians need to be equipped and trained and have to be informed of the safety risks associated with handling refrigerant gases.”

He added, there can also be informational barriers for large consumers or end users on the safe disposal of equipment at EOL, including the location of nearest reclamation/ destruction facilities. Additionally, he said, due to absence of national certification procedures for personnel, availability of trained person power is also a barrier.

Spanish market adopting to F-gas regulation in record time, says AEFYT Industry making an effort; taxes are a bottleneck, says Deputy Manager

By Hannah Jo Uy | Assistant Editor

T

he Spanish HVACR market is adapting to market conditions, despite the increasingly stringent policies being rolled out across Europe in compliance with the F-Gas Regulation, said Félix Sanz, Deputy Manager, AEFYT. “Like other European associations, AEFYT thinks that the roadmap imposed [by F-gas regulation] has not taken into account state-of-theart technology,” he said, “but the industry has made a great effort and is reacting in an exemplary manner.”

Félix Sanz

Speaking on emerging trends in Spain, Sanz said that commercial refrigeration has seen a shift towards new refrigeration systems with CO2, propane and ammonia.

“As far as refrigerant gases are concerned, we detect that natural refrigerants will coexist with the new mixtures that have a low (global warming potential) GWP,” he added. Sanz said that the maintenance of refrigeration installations also takes centre stage under the premise of recovery and recycling, all in the interests of energy efficiency, which, he said, is a main concern for stakeholders in the refrigeration industry.

Sanz said that a negative consequence that has been of concern of late, is the expanding black market related to HFC gases, in Spain and across Europe, owing to a tax on fluorinated gases making things difficult for stakeholders in the industry.

LEED rating system will soon become an international standard LEED v4.1 is an incremental update, which enhances the rating system’s inclusivity and transparency, USGBC says

By Ranjana Konatt

T

he LEED rating system will soon become an international standard for the construction, design and operation of high-performance structures, said Marisa Long, Vice President, Communications, U.S. Green Building Council (USGBC), while talking about the latest version of the rating system. “LEED v4.1 is the newest update to the rating system that debuted earlier this year and is not a full version change, rather it is an incremental update, which enhances the rating system’s inclusivity and transparency,” she said. The new updates will make achieving the certification more accessible, while encouraging continuous improvement and emphasising on performance, said Long.

Long said, “LEED v4.1 focuses on a performance-based approach that calls for measurable results throughout a building’s lifecycle.” She explained that in addition to looking at strategies, it is about understanding how the strategies affect the people living inside the building. She further said that LEED v4.1 encourages smart grid thinking and rewards projects that participate in demand-response programmes, while understanding how the materials used in construction impact health and the environment. “LEED is a cost-effective solution that continues to transform the built-environment and space, where people live, work, learn and play,” said Long.

While explaining how the certification is likely to give a boost to the zero emission school of thought, Long said, “Existing buildings and transit projects using LEED v4 have the option of pursuing certification using Arc, a state-of-the-art digital platform which benchmarks, tracks and monitors performance.” She further said that the platform provides building owners and operators with a way to track net-zero carbon emissions associated with energy and transportation, in addition to an array of other performance data, including water, waste and human experiences. Elaborating on the platform, she said, “Arc generates a performance score between zero and 100 and provides greater transparency, while holding projects accountable for their actions.” The score, she added, helps communicate progress to stakeholders and helps identify areas for improvement.

“Net-zero cities are the future, and LEED provides a holistic approach, which will help buildings and cities take the necessary steps to reach that goal.”

These issues, he added, were part of the key takeaways that will be highlighted in the Symposium of the Spanish Refrigeration and Air Conditioning Industry, which, he said, will address the new Spanish and European regulations related to the circular economy, security and digital transformation.

“These include the Directive on Ecodesign and Energy Labelling of Refrigerated Furniture, the certification of supermarket furniture and numerous issues related to energy efficiency,” he added. These issues, Sanz said, are being discussed in the move to highlight the refrigeration industry, as a leading sector, in a sustainable economy, at the service of society.

N

ew York and Maryland made announcements on September 11 that they will follow in California's footsteps, by adopting regulations aimed at phasing out hydrofluorocarbon (HFC) refrigerants, AHRI said in a Press communiqué. In New York, Governor Andrew Cuomo tasked the Department of Environmental Conservation (DEC) with promulgating the regulations, the communiqué said. In Maryland, the Department of the Environment will take the lead, the communiqué further said.

According to AHRI, Governor Cuomo announced that the phase out will be implemented from 2020 to 2024, with the intended goal of reducing HFC emissions by more than 20% by 2030. The DEC has said that, as part of a preproposal phase, it plans to schedule an initial stakeholder webinar and would like to begin collecting comments before the end of the year, the communiqué said. Following this initial outreach, the DEC will release a first draft of the rules, kick-starting a 60-day comment period, before issuing a final rule, the communiqué further said. The DEC will likely schedule public hearings at the State Capitol in Albany to provide an opportunity for comments from interested stakeholders, the communiqué added.

Maryland has yet to share the specifics of its plan, but will likely conduct a similar public rulemaking process, the

more cost-effective solution to customers in the precinct.”

Evans said the system also offers increased reliability. “About a year ago there were severe black outs in the state of South Australia, due to large storms, which damaged the transmission infrastructure of the electricity grid,” he explained. “What we have done to combat this in the future, is provide the site with its own generation and storage. We insulate the development from reliance on one source of energy. ” Eventually, Evans said, the project will house 2,000 individual homes, businesses and universities as part of the overarching scheme.

communiqué said. The Maryland Department of the Environment has indicated that it intends to adopt regulations similar to California, the communiqué further said. This effort will help Maryland achieve the goals set forth by the state's Greenhouse Gas Emissions Reduction Act of 2016, the communiqué added.

According to AHRI, the governors of California, Maryland and New York all belong to the U.S. Climate Alliance, a coalition of governors from 16 states and Puerto Rico, who have committed to undertaking various initiatives aimed at reducing greenhouse gas emissions. The communiqué said it is possible that other states involved in the Climate Alliance will announce similar plans to phase down HFCs. The communiqué added that AHRI has been actively involved in the rulemaking process in California, and will be similarly monitoring and engaging throughout the rulemaking processes in Maryland, New York and any other states that announce similar initiatives.

Evans added that the company was committed to providing energy to costsensitive connected customers at a competitive price, especially with recent substantial increases in electricity and gas prices. “We have committed to making sure that there are discounts with the cost of energy supplied to customers and the combination of grid and on-site generation ensures we provide a cost-effective solution,” he said. In addition to providing electricity, Evans said, the company is providing thermal energy for District Cooling and heating. “For the chilled water we are intending to provide a District Cooling system using chilled water,” he said. “We are also proposing to implement smart city infrastructure to provide additional amenities and convenience to the precinct.”

Evans said he believes there is great scope for similar schemes in other parts of the world. “Generally, where there is a degree of energy intensity, such as cooling, there is

great scope to provide an economic District Cooling system,” he said. “The challenge is bringing the smarts as to how it is designed and operated and to create savings that can be passed on to customers.”

Collaboration, Evans said, remains critical and design is continuous. “This really has been a true partnership with the government and we worked closely to understand what they wanted to create in the first instance and also to ensure we had a good understanding of how the development is working,” he said. “The state government is responsible for selling the land and we need to know what it is thinking.” Evans added that the state government played a vital role in engaging developers that were going to be connected to the scheme, providing a clear idea of the business they aimed to bring, stressing that upfront engagement has been important for a successful outcome.
