LETTER<br />

TO THE INDUSTRY<br />

The Year of Sustainability<br />

In January, the President of the UAE, His Highness Sheikh<br />

Mohamed bin Zayed Al Nahyan, announced <strong>2023</strong> as the<br />

‘Year of Sustainability’. The announcement is fitting, given<br />

that the UAE is set to host the COP28 meeting later this<br />

year. As HVACR stands front and centre in discussions<br />

related to sustainability, especially in a region dependent<br />

on cooling, it is clear that our industry cannot sit on the<br />

sidelines and simply watch.<br />

The industry invests billions every year in research and<br />

development, and great advancements in sustainable<br />

cooling solutions have been brought forward over the<br />

past decade. But what more can the industry do if all<br />

these solutions, and state-of-the-art technologies, are<br />

ignored, misunderstood, wrongly selected and specified,<br />

badly installed and operated and maintained by untrained<br />

personnel? What sense does it make to discuss minimum<br />

energy requirements on legislative levels when we lose<br />

30-40% of efficiency in the field?<br />

We need to see a big push towards education and training<br />

to ensure our discussions related to sustainability do not<br />

equate to merely greenwashing. Over the years, Eurovent<br />

Middle East has organised numerous conferences,<br />

workshops, and webinars to increase awareness among<br />

MEP engineers and cultivate greater awareness of<br />

the latest standards, industry recommendations, and<br />

technologies. It has been a good and justified start, but we<br />

know we need more.<br />

Offerings for continued education and skill development<br />

for our industry are scarce in the Middle East. Yet<br />

we badly need better-informed engineers and bettertrained<br />

technicians. This is why our members invested<br />

significant time and efforts into creating a more substantial<br />

educational programme which we will launch in the fall,<br />

right ahead of COP28. It is time that this lack of education<br />

and training is addressed.<br />

The industry shows that by working together, putting<br />

competion aside for the benefit of all, great initiatives<br />

can happen. This is the spirit of an association, and this<br />

is what Eurovent Middle East stands for and is all about.<br />

Our members once more show their commitment to great<br />

corporate social responsibility, putting people first, and<br />

caring for the region and the planet.<br />

We invite all of you to join our efforts to educate the<br />

market. Let the Year of Sustainability be marked by action,<br />

and not merely words. It is time to make a difference.<br />

LEAD STORY<br />

Setting the right limit: temperature<br />

control in the UAE<br />

Several years ago, the UAE implemented a regulation which intended to limit the<br />

lowest temperature set point to 20 degrees Celsius. While a laudable attempt to<br />

cultivate more conscious energy consumption, the regulation has its difficulties.<br />

Eurovent Middle East speaks to experts to know more about this requirement and<br />

its effects.<br />

In its constant drive towards<br />

sustainability, the UAE, some years<br />

ago, had implemented a paragraph<br />

requiring temperature controls<br />

to be limited to 20 degrees C. The<br />

regulation was created as part<br />

of the country’s strong initiative<br />

to pursue energy efficiency and<br />

sustainability. In its last revision, the<br />

regulation also required proof that<br />

the unit would cut off when the room<br />

temperature reached 20 degrees.<br />

While positive in its intention, the<br />

requirement raised concerns among<br />

manufacturers.<br />

A challenging limit<br />

Markus Lattner, Managing Director<br />

of Eurovent Middle East, explains<br />

the background: “Many people use<br />

air conditioning to its maximum,<br />

regardless of the actual need and<br />

going beyond comfortable levels.<br />

The best indoor temperature setting<br />

for maximum comfort lies between<br />

20- and 24-degrees C. However,<br />

many people still set the controls<br />

down to below 20, which is just a<br />

waste of energy and is, in fact, not<br />

even healthy for occupants. The<br />

regulation intends to enforce a<br />

technical stop to such practises.”<br />

Explaining the regulation in detail<br />

is Srinivasan Rangan, Director<br />

of Demand Generation, Strategy<br />

and Regulatory Affairs, Rheem<br />

Manufacturing: “Thermostats for<br />

the ducted and non-ducted DX<br />

Air conditioners below 65.000 Btu<br />

are required to have factory set<br />

temperature limits of 20 degrees<br />

C with a factory set lock or cut off<br />

limit at 18 degrees, which prevents<br />

it from being used below that point,”<br />

he says, referring to the UAE.S<br />

5010-1 regulation for residential air<br />

conditioning.<br />

From a technical perspective,<br />

there is no problem with limiting<br />

the set point to 20 degrees C, says<br />

Luay Ghussein, Senior Director of<br />

Engineering, Taqeef. “Whoever can<br />

set the limit at 18 degrees C, can<br />

set the limit at 20 degrees C,” he<br />

says, stressing that the complexity<br />

comes in doing this in the face<br />

of the lack of harmonisation in<br />

the region. Ghussein explains:<br />

“When you do something for a<br />

relatively small market, such as<br />

the UAE, that becomes a challenge<br />

to manufacturers. Because<br />

to make any price affordable,<br />

manufacturers worldwide try to<br />

unify their products so there is<br />

some compatibility crossover and<br />

to ensure the availability of spare<br />

parts. This is why it's much easier<br />

if the whole region has the same<br />

one. The limitation to one market is<br />

a barrier, and manufacturers aim<br />

Markus Lattner Rangan Srinivasan Luay Ghussein<br />

for the best solution in terms of<br />

commercial viability, rather than<br />

the ideal one.”<br />

Elaborating further, Ghussein<br />

says an important commercial<br />

consideration would be stocking<br />

material in the UAE. “With this<br />

regulation, we would have to<br />

manage the stock to know which<br />

controls can and cannot be sold<br />

within Dubai, and it becomes a bit<br />

of a logistics problem,” he says.<br />

“This could lead to an increase in<br />

price and situations wherein the<br />

air conditioning unit with controls<br />

that go to 20 degrees C will be<br />

more expensive than the ones that<br />

have the limit for 18 degrees C<br />

for no other reason than to absorb<br />

the cost of logistics and cost of<br />

compliance because there will be<br />

no other choice than to charge the<br />

end consumer.”<br />

Economies of scale, Ghussein<br />

explains, will mean the market<br />

with fewer units will always<br />

experience higher pressure in<br />

terms of price. “The market<br />

will be most viable and able to<br />

comply if such a regulation can<br />

be harmonised throughout the<br />

region, which is what we urge the<br />

bodies to consider,” he says.<br />

Areas of improvement<br />

Another point of possible Another<br />

point of possible contention<br />

regarding the regulation,<br />

Ghussein explains, is the testing<br />

method that should be used.<br />

“There is no standard that defines<br />

the test method they want to have<br />

or use,” he says. “AC discharge<br />

temperatures (air leaving the AC)<br />

are typically 12 or 13 degrees C<br />

to achieve a room temperature of<br />

20-24 degrees C, as air in the room<br />

must mix. The mix will give it the<br />

20 degrees C temperature, not the<br />

discharge, and it won’t be unified<br />

in the entire room. So, it’s about<br />

where you measure that 20 degrees<br />

C. The world usually tests it on the<br />

return air temperature, but the<br />

current regulation is unclear about<br />

this.”<br />

This is also a concern for Rangan.<br />

“Accurately measuring room<br />

temperature and controlling the<br />

air conditioning unit can also be<br />

a technical challenge to ensure<br />

compliance,” he says. “A testing<br />

standard and protocol must be<br />

clearly defined, including the<br />

location of sensors and measuring<br />

positions at return air temperature.<br />

We must consider the techno<br />

commercial and practicality<br />

that any password control for 20<br />

degrees C is applicable for 18<br />

degrees C, so keeping two separate<br />

provisions is challenging.”<br />

Ghussein underlines again that<br />

Ghussein underlines again that<br />

the only well-known standard<br />

tests the temperature based on<br />

a certain point at the return air.<br />

“Worldwide, this is how the set<br />

point is tested,” he says. “It’s<br />

not just any particular point. It is<br />

important for the regulation to be<br />

easily enforceable without burdening<br />

manufacturers. That means they<br />

don’t define a different test method<br />

or set point other than the globally<br />

accepted standard, or else it would<br />

not be realistic. The regulation is<br />

one aspect, but the testing method<br />

is equally important; the testing<br />

method should be the same for any<br />

set point, making the manufacturer's<br />

life much easier.”<br />

Rangan says another challenge<br />

is defining the room size and<br />

boundaries, especially for irregularly<br />

shaped or open-plan spaces.<br />

“Managing user behaviour is also<br />

important to ensure compliance<br />

with regulations, as it can affect<br />

the temperature in the room,” he<br />

says. “Overcoming these challenges<br />

requires understanding the<br />

regulations and air conditioning<br />

systems, as well as effective<br />

communication with users.”<br />

Working towards ease of<br />

enforcement<br />

Ensuring that test methods echo<br />

or subscribe to global accepted<br />

methods is not only critical to<br />

support manufacturers in the<br />

region, having a regulation that<br />

may be difficult to enforce can also<br />

have long-term implications. “If a<br />

regulation requests for something<br />

impossible to test for and especially<br />

difficult to comply with, people<br />

may cut corners,” says Ghussein.<br />

Rangan also points out that there<br />

is a potential risk that regulations<br />

would be bypassed through the<br />

use of non-compliant thermostats<br />

available in the free market, as they<br />

are sometimes procured separately<br />

by customers or via e-commerce.<br />

“There is a need for uniform<br />

regulation application on other<br />

cooling systems such as chilled<br />

water systems.”<br />

Rangan further underscored<br />

that a lack of compliance and<br />

reduced accountability could lead<br />

to decreased safety and comfort<br />

for occupants, increased costs for<br />

individuals and businesses, and<br />

negative environmental impacts.<br />

“A lack of enforcement can erode<br />

confidence in regulatory systems,<br />

leading to a loss of trust for<br />

regulations,” he says.<br />

How this regulation will be managed<br />

within Building Management<br />

Systems (BMS) is another important<br />

aspect that needs to be addressed.<br />

Ghussein and Rangan believe it will<br />

add another layer of complexity<br />

to the discussion. “It’s unclear<br />

how they will regulate all the BMS<br />

coming into the market,” Ghussein<br />

says. “There would be a need to<br />

connect the unit to the BMS, the<br />

system should also ensure that the<br />

AC doesn’t go below 20 degrees C.”<br />

Currently, adds Rangan, remote or<br />

BMS controls are not regulated.<br />

Recommendations on the best way<br />

forward<br />

Without a doubt, the regulation<br />

will go a long way in achieving<br />

greater savings. “As an industry,<br />

we support the regulation to that it<br />

saves energy,” Ghussein reiterates.<br />

“In some countries, such as Japan,<br />

building codes have even been<br />

forbidden going below 24 or 25<br />

degrees C, which underscores the<br />

clear value behind having such a<br />

regulation. So yes, it’s good to have<br />

such a regulation. The question is,<br />

is the current requirement effective<br />

and working?”<br />

Rangan says that the importance of<br />

Rangan says that the importance of<br />

clearly defining testing standards<br />

and protocols for all thermostats<br />

entering the UAE should be<br />

emphasised. “The regulations<br />

should be uniformly applicable<br />

to all types of thermostats,<br />

and the exceptions process<br />

should be clearly defined,”<br />

he says. “This is because<br />

some end-use applications<br />

may not be practical to apply<br />

the regulations, for example,<br />

cold storage, pharmaceutical<br />

or hospital applications.<br />

Additionally, suppliers should be<br />

well protected in case of misuse<br />

of the thermostat settings in the<br />

field.”<br />

According to Rangan, several<br />

According to Rangan, several<br />

measures can improve<br />

compliance with regulations<br />

related to air conditioning<br />

units not cooling below a<br />

certain temperature. “Clear<br />

and consistent definitions of<br />

key terms and standardised<br />

measurement protocols are<br />

critical to ensuring effective<br />

implementation,” he says.<br />

“Certified testing organisations<br />

should also be required to<br />

test compliance with the<br />

regulations, and the regulations<br />

should be part of broader<br />

energy efficiency standards.<br />

Public education and outreach<br />

can also help raise awareness<br />

and promote compliance.”<br />

Lattner sums up the concerns of<br />

the industry, “The regulation in<br />

its current form is not achieving<br />

its goals. It doesn’t address<br />

applications where you need<br />

lower temperatures, leads to<br />

unfair competition in the market<br />

and leaves way too much room<br />

for circumventions. People will<br />

not understand why their AC<br />

can’t go lower when at the next<br />

location, the room temperature<br />

is clearly lower due to nonregulated<br />

BMS systems or a<br />

third-party remote control. We<br />

absolutely support its intention,<br />

but this issue may better be<br />

addressed through building<br />

codes and public awareness<br />

campaigns.”<br />

Gopalakrishnan G, Operations<br />

Director, Emrill, an integrated<br />

facilities management company, is<br />

a firm believer in the importance of<br />

quality installation within the sector.<br />

“HVAC has many areas requiring<br />

specialist expertise,” he says.<br />

“Qualified and licensed technicians<br />

and engineers across the UAE<br />

possess the required skillsets to<br />

install and maintain HVAC systems<br />

efficiently.”<br />

However, complaints have emerged<br />

in the GCC region due to improper<br />

or inefficient installations, which<br />

not only put to risk the reliability<br />

of a system but also lead to<br />

costly maintenance or greater<br />

consumption due to it not operating<br />

as intended. Several common<br />

installation issues can be seen with<br />

DX air conditioning installations,<br />

says Srinivasan Rangan, Director<br />

of Demand Generation, Strategy<br />

and Regulatory Affairs, Rheem<br />

Manufacturing. “These include<br />

incorrect sizing, poor placement<br />

of the indoor and outdoor units,<br />

improper refrigerant charge,<br />

inadequate insulation, and poor duct<br />

design,” he says. “Additional factors<br />

that can contribute to issues with<br />

air conditioning systems include<br />

improper implementation,” he<br />

says, providing the example of low<br />

side static exceeding equipment<br />

design, hot air recirculation caused<br />

due to the equipment being placed<br />

too close, which does not follow<br />

the manufacturer‘s installation<br />

guidelines, as well as poor quality<br />

of refrigerant piping and inadequate<br />

brazing of joints or leakage in airflow<br />

ducts.<br />

For Hadi Ismail, Chief Sales Officer,<br />

Taqeef, improper installation<br />

practices are cost driven. “Often,<br />

when installers do not follow<br />

manufacturers' instructions or<br />

recommendations, the reason<br />

is purely economic,” he says. “A<br />

common example in the UAE is that<br />

they don’t install return duct to save<br />

money because it's expensive.”<br />

Gopalakrishnan points out, however,<br />

that with the number of HVAC<br />

solutions in the market, there is also<br />

an unavoidable learning curve. “FM<br />

is a fast-evolving sector,” he says.<br />

“With the implementation of any new<br />

product or service, there will be a<br />

learning curve across the industry,<br />

where support may be required from<br />

our original equipment manufacturer<br />

partners.”<br />

Why does it matter?<br />

NEWSLETTER<br />

What’s causing inefficient installations<br />

and why you should care<br />

Proper installation is a critical part of the project process that can significantly impact an<br />

HVAC system's efficiency, lifecycle, and overall performance. However, there are many<br />

cases in which quality installation is overlooked or simply not given the necessary attention<br />

it deserves. Eurovent Middle East looks at how poor installation processes lead to wrong or<br />

inefficient performance and operations and the reasons why…<br />

Gopalakrishnan G<br />

Subpar installation practices,<br />

unfortunately, has a number of<br />

consequences. Rangan explains<br />

that these issues he highlighted<br />

can result in inefficient operation,<br />

increased energy consumption,<br />

and costly repairs. “Proper<br />

installation, regular maintenance,<br />

and attention to these issues can<br />

help ensure optimal performance<br />

and longevity of the system,” he<br />

says. “If the air conditioning unit<br />

is not sized properly or has an<br />

incorrect refrigerant charge, it can<br />

lead to reduced efficiency, increased<br />

energy consumption, and a shorter<br />

lifespan. Similarly, insufficient<br />

insulation and poor duct design can<br />

cause inadequate cooling, increased<br />

energy consumption, and costly<br />

repairs. Regular maintenance<br />

and attention to these factors are<br />

crucial for optimal performance<br />

and longevity of the system.” All<br />

these factors, he says, will have<br />

an adverse impact on the cost of<br />

ownership and home comfort for<br />

end users.<br />

Ismail says there are also critical<br />

energy efficiency implications.<br />

“For example, when you don’t add<br />

a duct, the air is taking a path that<br />

it shouldn’t,” he explained. “And<br />

the way it was manufactured and<br />

tested, it was meant to have duct on<br />

the outlet and inlet, so having the<br />

air going through the false ceiling<br />

in either kitchen or bathroom, two<br />

typical places installed, is simply an<br />

inefficient use of energy.”<br />

What contributes to the issue?<br />

While the challenges listed<br />

above can lead to errors during<br />

installation, poor performance,<br />

reduced efficiency, and demotivation<br />

among installers, Rangan believes<br />

that proper education and training,<br />

fair compensation and working<br />

conditions, access to specialised<br />

tools, and opportunities for<br />

professional development are<br />

critical to overcoming them. “The<br />

two main factors behind this<br />

problem are a lack of training<br />

and, at times, improper tools<br />

and equipment,” he reiterates.<br />

“Additionally, technicians in the GCC<br />

come from different parts of the<br />

world, and there is no consistency in<br />

qualification,” he says.<br />

In this case, cultivating awareness<br />

is key, says Ismail, “We need to<br />

raise awareness across the entire<br />

value chain, from the consultant,<br />

contractor to the installer, so that<br />

they know that ensuring good<br />

installation does not have to be<br />

expensive,” he says. “Even as simple<br />

as ensuring the outdoor unit is<br />

installed in the shade and protected<br />

from direct sun exposure is already<br />

an example of how it could save<br />

money.” The problem, he says, is<br />

CAPEX vs OPEX, and contractors<br />

don’t do more than they are asked<br />

to do.<br />

Within Emrill, Gopalakrishnan says<br />

that they ensure their technicians<br />

undergo the required training and<br />

are qualified to install, repair, and<br />

maintain HVAC systems to deliver<br />

exceptional service and ensure<br />

client satisfaction. “As an essential<br />

asset in buildings, HVAC repair<br />

and maintenance is prioritised,<br />

especially in the summer months<br />

when the systems need to operate<br />

efficiently to meet the demand of<br />

higher temperatures,” he says.<br />

Rangan adds that this has been<br />

a priority for Rheem which trains<br />

and certifies technicians in the<br />

Rheem Innovation Centres across<br />

the Middle East. “Proper training<br />

of air conditioning installers can<br />

result in several benefits, including<br />

increased efficiency, improved<br />

quality of installations, enhanced<br />

safety, reduced call backs, and<br />

increased customer satisfaction,”<br />

he says. “Trained installers can<br />

Rangan Srinivasan<br />

work more efficiently, ensuring that<br />

installations are performed correctly<br />

and to industry best practices,<br />

which can lead to cost savings for<br />

customers and reduced repair and<br />

maintenance costs.” Rangan adds<br />

that proper training can also help<br />

identify potential safety hazards<br />

during the installation process,<br />

reducing the risk of accidents or<br />

injuries. “Reduced call backs and<br />

increased customer satisfaction<br />

can lead to positive word-of-mouth<br />

referrals and long-term growth for<br />

businesses,” he says.<br />

A holistic building code<br />

Although skill plays a role in<br />

ensuring efficient installation,<br />

Ismail believes a greater issue<br />

could be challenges related to<br />

building codes. “If people aren’t<br />

forced to do something, they often<br />

don't,” he says, pointing out that<br />

current building codes do not place<br />

accountability on the installer's<br />

role in the building operations. This<br />

becomes worse, he adds, given the<br />

move to cut costs. “Even if installers<br />

are aware of best practices, the<br />

imperative to drive costs down<br />

means that cheaper often wins,<br />

which often results in shortcuts.“<br />

As such, Ismail says a holistic<br />

building code that empowers end<br />

users would be helpful. “Sometimes,<br />

educating people to buy a more<br />

highly efficient machine is not<br />

always enough,” he says. “In the<br />

Hadi Ismail<br />

UAE, the end user rarely decides<br />

which AC system is installed or<br />

what kind of ducts are in the home.<br />

A more holistic building code that<br />

mandates installation according to<br />

manufacturers' recommendations<br />

would be very helpful.” Ismail points<br />

out that in Europe, even though<br />

energy savings and education were<br />

at the forefront of efforts to increase<br />

quality and standards, it had to be<br />

mandatory or enforced by law to<br />

avoid cost competition through cost<br />

savings. “You need to walk with both<br />

legs, not one. You can’t compensate<br />

for the weakness in one field by<br />

improving only one part,” he says.<br />

Gopalakrishnan adds that stronger<br />

integration among stakeholders,<br />

including consultants, contractors<br />

and the manufacturer would also<br />

be helpful. “We work closely with<br />

our clients and partners to ensure<br />

any challenges that may arise<br />

are planned for, appropriately<br />

managed, and suitable solutions<br />

are proposed” he says. “We always<br />

suggest the involvement of a FM<br />

service provider in the early design<br />

stages of a project to increase the<br />

benefits to stakeholders. Adopting<br />

this approach allows for input from<br />

a post-build operational perspective,<br />

with healthy challenges on design<br />

decisions that may cause variation<br />

costs at a later stage once the<br />

project is operational or inhabited by<br />

residents.”<br />

Eurovent Energy Label for Air Filters<br />

The Eurovent ‘Energy Efficiency Evaluation of Air Filters for General Ventilation Purposes’ is<br />

a valuable, effective, yet largely underutilised tool, especially in projects across the Middle<br />

East. Here’s how the guideline can unlock better energy saving, more sustainable operations<br />

and ensure greater quality of health.<br />

The undeniable savings of energy-<br />

efficient filters<br />

The energy savings that can be<br />

unlocked with more efficient filters<br />

have long been proven. Providing<br />

numbers to back this claim,<br />

Stephane Ruiz, Managing Director,<br />

Camfil Middle East, shares that<br />

generally, for commercial buildings,<br />

50% of the energy bill is related to<br />

the HVAC system and 30% of this<br />

cost is roughly linked to the air<br />

filters. “Using energy-efficient filters<br />

will usually provide a +20% of energy<br />

savings,” he says.<br />

Sami Akaydin, Technical Manager,<br />

TROX Middle East, agrees, further<br />

explaining that investing in quality<br />

energy-efficient filters essentially<br />

means investing in filters that offer<br />

less resistance than standard filters.<br />

“Filters are supposed to separate<br />

particles in the air – and they are an<br />

obstacle to the airflow,” he says. “As<br />

the differential pressure increases,<br />

the energy efficiency decreases.<br />

The goal is minimising the loss.” He<br />

further explained that filter media<br />

with extremely fine pleats and<br />

aerodynamically optimised filter<br />

units could help to save up to 50%<br />

energy compared to conventional<br />

filters.<br />

savings, high-quality filters also<br />

improve the overall efficiency of<br />

HVAC systems and ensure the<br />

systems' cleanliness while reducing<br />

the associated maintenance costs,<br />

says Ruiz. “HVAC’s component<br />

lifespan will be extended with quality<br />

air filters,” he says. “Furthermore,<br />

high-quality filters don’t need to be<br />

replaced as often as lower quality<br />

filters, which result in less waste<br />

disposal and lower maintenance<br />

costs.”<br />

However, the benefits of quality<br />

filters on occupant health are<br />

perhaps of the most significant<br />

concern for those who advocate for<br />

using quality air filters. “Effective<br />

and highly efficient filter systems<br />

filter dust, bacteria and pollen out<br />

of the ambient air, ensuring that we<br />

can breathe clean air in enclosed<br />

indoor spaces,” Akaydin says.<br />

“Alongside the system efficiency<br />

Sami Akaydin<br />

factor, the air quality achieved by<br />

the air handling unit system is<br />

increasingly becoming an important<br />

focal point for regulatory bodies<br />

worldwide.” Ruiz reiterated this by<br />

saying, “The aim is to protect people<br />

by reducing sick leave, increasing<br />

their productivity and ensuring<br />

wellbeing at the same time.”<br />

The increasing focus on the<br />

importance of thermal comfort and<br />

room air quality among legislators<br />

could also be traced to proven<br />

economic benefits, Akaydin adds,<br />

pointing to the work of William J.<br />

Fisk, 'Health and Productivity Gains<br />

from Better Indoor Environments’.<br />

The report, he explains,<br />

demonstrated the economic returns<br />

of good indoor environmental quality,<br />

such as a 20 to 50% reduction in sick<br />

A valuable yet underutilised tool<br />

Given the holistic benefits of<br />

quality air filters, consultants and<br />

project owners must choose the<br />

most optimum filters for their<br />

respective facilities. This may not<br />

always be straightforward, given<br />

that each project is different, and<br />

many solutions are available in the<br />

market. “Filters look the same<br />

from the outside, but the way they<br />

behave from one to another can<br />

present many differences,” says<br />

Ruiz. “It is crucial for consultants to<br />

understand the effect and benefits<br />

of the filters on the HVAC system,<br />

and its impact on sustainability,<br />

energy use, waste disposal and<br />

occupant health.”<br />

Eurovent offers excellent guidance<br />

for consultants and project owners<br />

to navigate the thin line between<br />

energy efficiency and filtration<br />

requirements. The ‘Eurovent<br />

Recommendation 4/23 – 2022:<br />

Selection of EN ISO 16890 rated air<br />

filter classes’ provides clarity on<br />

implementing the newest global<br />

standard on air filtration, while ‘The<br />

Energy Efficiency Evaluation of Air<br />

Filters for General Ventilation’ gives<br />

a good understanding of how the<br />

filters perform but also will point out<br />

some technical differences between<br />

several filters.” says Ruiz.<br />

Eurovent Certification tests and<br />

certifies air filters according to their<br />

filtration and energy consumption<br />

characteristics and provides an<br />

energy label that helps consumers<br />

make the best choice. It is based on<br />

ISO 16890-1:2016 and is a third-party<br />

certification providing information<br />

such as pressure drop, ePM<br />

efficiency, energy rating and annual<br />

energy consumption. This is crucial<br />

to understand the saving potential of<br />

filters without reducing the filtration<br />

efficiencies.<br />

Providing an example, Ruiz says,<br />

“If we look at a standard ePM1 60%<br />

filter that is B rated, with an energy<br />

consumption of 1054kWh/a and<br />

compare it to the same efficiency<br />

filter that is A+ rated with an energy<br />

consumption of 811kWh/a. By simply<br />

switching filters, a company can save<br />

over 240kWh/a per filter.” Compared<br />

to lower classes, the energy saving<br />

outnumbers the higher investment<br />

costs, usually within few months,<br />

significantly reducing operational<br />

costs.<br />

What the guideline has to offer<br />

Akaydin adds that the tool is<br />

especially valuable considering the<br />

standard testing procedure for large<br />

and fine dust filters has changed.<br />

“Filter performance is now no<br />

longer assessed based solely on a<br />

laboratory test method but on real<br />

application conditions,” he says.<br />

“Previously, in accordance with EN<br />

779, a synthetic aerosol was used<br />

for testing, with a standard particle<br />

size of 0.4µm. The new ISO 16890<br />

standard is based on a range of<br />

particle fractions, and tests are<br />

conducted using DEHS and KCl test<br />

aerosols.”<br />

Under the evaluation, Akaydin<br />

explains that filters are divided into<br />

four groups:<br />

• ISO Coarse (rated<br />

containment capacity against ISO A2<br />

dust)<br />

• ISO PM10: Fine dust<br />

particles ≤ 10 µm<br />

• ISO PM2.5: Fine dust<br />

particles ≤ 2.5 µm<br />

• ISO PM1: Fine dust particles<br />

≤ 1 µm<br />

• Filter performance is now<br />

measured with three different<br />

particle fractions (PM1, PM2.5,<br />

PM10).<br />

“This test scenario allows the<br />

tester to examine the local fine<br />

dust pollution more closely, based<br />

on data from official measuring<br />

stations, for example, and to select<br />

a filter appropriate for the quality of<br />

the supply air,” he says.<br />

Akaydin adds that alongside<br />

the filter performance, another<br />

important aspect to consider is the<br />

energy performance of the filter in<br />

day-to-day use. “The outdoor air<br />

(ODA) quality requirements have<br />

also been redefined,” he says. “The<br />

categories ODA 1 to ODA 3 must now<br />

be determined based on loading<br />

with O-zone, NO2, SO2 and PM10,<br />

in accordance with the revised<br />

regulations published by the WHO<br />

in 2005 (superseding 1999 version).<br />

These categories are important in<br />

determining which air filter should<br />

be fitted in the AHU. The definition of<br />

supply air (SUP) quality, divided into<br />

five categories, has also been added<br />

to the standard.”<br />

Akaydin also says the New Energy<br />

Efficiency Classification table from<br />

Eurovent, which shows kWh's<br />

annual energy consumption (AEC)<br />

based on standard test conditions,<br />

is very beneficial for projects. “Air<br />

filters of the lowest energy efficiency<br />

Class E consume more than twice<br />

as much energy as the best Class A+<br />

filters,” he says.<br />

Providing an example, filter of<br />

category ePM1 > 50% (previously<br />

F7) could give both results<br />

below depending on the different<br />

efficiencies:<br />

• One piece Class A+ filter that<br />

consumes up to 800 kWh incurs<br />

energy costs of AED 328 per<br />

year.<br />

• One piece Class D filter that<br />

consumes up to 2,000 kWh<br />

incurs energy costs of AED<br />

820 per year. (Considered<br />

commercial rate per kWh of<br />

AED 0.41 in the UAE)<br />

The difference in energy costs,<br />

therefore, is AED 492 at a volume<br />

flow rate of 3,400 m3/h, ensuring<br />

60% is saved per year per filter.<br />

“Filters are more than just an<br />

investment in room air quality –<br />

they‘re an investment in efficiency,<br />

too,” he adds.<br />

A critical tool for the Middle East<br />

While an effective and advantageous<br />

tool, experts believe the guideline<br />

remains underutilised in the Middle<br />

East. “We are living in a beautiful<br />

region which is close to the desert,<br />

but, unfortunately, this brings its<br />

challenges, such as a cocktail of<br />

sand and wind, which is not so good<br />

for our lungs,” says Ruiz. “Indoor<br />

air quality can even be worse than<br />

the outside air quality, and looking<br />

at the outdoor dust concentration<br />

values in UAE, we can imagine why<br />

efficient air filters are so important.”<br />

However, Ruiz says, quite often<br />

in the region, the selection and<br />

procurement of air filters are made<br />

on the acquisition cost and not based<br />

on a Total Cost of Ownership vision<br />

and strategy, “Projects driven by<br />

multinationals usually involve strong<br />

requirements when it comes to the<br />

air filtration part, mainly because<br />

these companies refer to their<br />

internal guidelines and processes,”<br />

he says. “For them, Energy Efficient<br />

Filters have many benefits for their<br />

facilities, processes, and people, and<br />

they understood this principle a long<br />

time ago.”<br />

Akaydin is optimistic that awareness<br />

on the importance of investing in<br />

quality filters will grow as the world<br />

becomes more conscientious of<br />

energy use. “Indeed, high-quality,<br />

efficient filters are not being used as<br />

they should be,” he says. “However,<br />

we expect an increase in demand<br />

as energy efficiency initiatives<br />

are becoming an essential part of<br />

government strategies worldwide<br />

as part of efforts to promote<br />

sustainability. The UAE's vision to be<br />

a global hub and a successful model<br />

of the new green economy is just<br />

one such example.”<br />

The silent killer<br />

Ruiz adds that even among<br />

consultants and property developers<br />

in the regions, efficient air filters,<br />

in terms of both energy and<br />

particulate matter, should be<br />

considered the key to sustainability.<br />

“Protecting people’s health and the<br />

next generation, making energy<br />

savings and generating less waste<br />

should be one of their priorities,”<br />

he says. “The COVID situation<br />

reminds us also how important it is<br />

to protect ourselves from airborne<br />

contamination.”<br />

As a final word, Ruiz offers a crucial<br />

reminder of air quality's massive<br />

impact on human health. “According<br />

to World Health Organization<br />

(WHO), more than 6.5 million people<br />

worldwide are dying prematurely<br />

each year due to air quality,” he<br />

says. “It is one of the major human<br />

threats, which was classified in 2013<br />

as carcinogenic by the International<br />

Agency for Research on Cancer, and<br />

unfortunately, we are not focusing<br />

enough on it. I think it isn't easy to<br />

understand and speak of something<br />

we cannot see. Air contamination is<br />

a silent killer that needs to be higher<br />

up on decision-makers agenda<br />

today. “<br />

Sponsoring an event? Here’s what you<br />

should do to get the most out of it.<br />

With exhibitions and conferences in full-swing post-pandemic, so is the efforts of events and<br />

organisers to lock in sponsorships. Mahyar Ebrahimi, Head of Content at Strategic Intelligence<br />

Forum, explains why a successful conference is not a one-sided journey and what most<br />

companies get wrong when participating in an event…<br />

Challenge the 'why'<br />

The conference landscape across<br />

the UAE has been booming, much<br />

to the excitement of communities<br />

eager for physical meetings<br />

following the long event slumber<br />

imposed by the Covid-19 pandemic.<br />

However, as events experience<br />

a post-Covid renaissance in a<br />

country that has already positioned<br />

itself as a hub that attracts<br />

Meetings, Incentives, Conferences<br />

& Exhibitions (MICE) participants<br />

worldwide, experts believe it’s<br />

also a ripe time for participants<br />

to thoroughly reflect on their<br />

participation to break the monotony<br />

and challenge the why of their<br />

investment.<br />

Mahyar Ebrahimi, Head of Content<br />

for Strategic Intelligence Forum<br />

is one such expert. Ebrahimi has<br />

worked on many large-scale and<br />

technical conferences in the region,<br />

including the Abu Dhabi Smart<br />

City Summits, the Retrofit Tech<br />

series of events, the RAK Energy<br />

Summit, and many more. Based<br />

on his observations, Ebrahimi<br />

urges companies to remember<br />

that successful participation<br />

in conferences is not a onesided<br />

journey. He explains that<br />

companies need an accurate and<br />

clear idea of such investments'<br />

tangible and intangible benefits, as<br />

mismatched expectations can lead<br />

to dissatisfaction. Thus, Ebrahimi<br />

challenges each company looking<br />

to participate in or sponsor an event<br />

to ask themselves: “Do you really<br />

know what you went to get out of<br />

it?”<br />

A missed branding opportunity<br />

Ebrahimi says this step is crucial<br />

as he believes not enough is done<br />

by companies to properly assess<br />

the unique benefits the different<br />

types of events have to offer.<br />

Differentiating between exhibitions<br />

and conferences, Ebrahimi<br />

points out that while exhibitions<br />

can have a conference element,<br />

and conferences often have a<br />

small exhibition outside, they’re<br />

fundamentally different to both<br />

audiences and potential sponsors<br />

and exhibitors.<br />

Touching on the typical packages<br />

companies opt for during these<br />

conference schemes, Ebrahimi says<br />

that companies commonly sponsor<br />

to get a speaking slot with an<br />

added option of an exhibition booth<br />

which they may or may not forego.<br />

Combined, they are a branding<br />

opportunity that would be unique to<br />

the sponsors, given that networking<br />

is a benefit available to both<br />

sponsors and paid delegates.<br />

However, what separates a<br />

successful participation from an<br />

unsuccessful one is determined by<br />

the quality of people designated to<br />

optimise the opportunity. Ebrahimi<br />

says, “Companies need to ask<br />

themselves; do I have the right<br />

people speaking? I’ve seen many<br />

companies that waste thousands of<br />

dollars for a speaking slot for 15-20<br />

minutes by having people that don’t<br />

have the skill set to make the most<br />

of the time they are given. If I had<br />

one piece of advice, as a consultant,<br />

I would say, to take the time to fix<br />

your presentation and have a good<br />

Mahyar Ebrahimi<br />

presenter that can communicate<br />

well in English. Even if you have the<br />

most technically knowledgeable<br />

expert presenting, if they are<br />

unable to communicate effectively,<br />

the audience will only capture<br />

the information they effectively<br />

communicate – the rest is always<br />

lost in translation.”<br />

Ebrahimi says the same thinking<br />

applies to sponsors investing in<br />

conference exhibition booths.<br />

“An exhibition slot increases your<br />

chance and provides an opportunity<br />

to meet clients, but it’s not magic,”<br />

he stresses. “For companies that<br />

say they didn’t get any sales, I’d<br />

urge them to look closer at their<br />

sales force. Are they well-equipped<br />

and well-informed to speak to the<br />

right people in the right way? That’s<br />

one of the most common problems<br />

in the Middle East.”<br />

For larger exhibitions, the lack<br />

of targeted audiences, partly<br />

due to broad attendee profiles,<br />

limited representation from key<br />

stakeholders and difficulty in<br />

reaching decision-makers can be an<br />

issue. Ebrahimi admits that HVAC<br />

audiences are not as abundant in<br />

many large-scale exhibitions. “I’ve<br />

had many people say I get more<br />

job applications than leads,” he<br />

says. “So, the metric for measuring<br />

audience quality is connected<br />

to measuring ROI. However, as<br />

mentioned, some exhibitors have<br />

no business development people<br />

at their booths and instead, opt<br />

for hired hosts or ushers. Others<br />

have their most junior salespeople<br />

manning the booths, while the<br />

more effective ones set out to get<br />

meetings and meet clients. And so,<br />

when they say they had the wrong<br />

audience in the room, I’d argue that<br />

they had the wrong people at their<br />

booths too.”<br />

He says this sets events and<br />

conferences in the Middle East<br />

apart compared to parallel events,<br />

such as ISH, largely considered the<br />

world's leading trade fair for HVAC<br />

and Water held in Germany, which<br />

often sees the best salespeople that<br />

companies have invested in training.<br />

Gauging interest and managing<br />

expectations<br />

The intention for pointing this<br />

out, Ebrahimi says, isn’t to deter<br />

manufacturers from participating<br />

and sponsoring events but merely to<br />

encourage more active participation<br />

to capture the opportunities in the<br />

market truly. “When it comes to<br />

branding, it’s about being seen,”<br />

he says. “Many consultants or<br />

developers have remarked that if a<br />

particular company is not in an event<br />

they are participating in, they might<br />

consider them not big enough of a<br />

player or think, ‘Oh, they must not<br />

be trying to get our business’. That’s<br />

often the binary factor in branding.”<br />

The second factor is placement,<br />

says Ebrahimi. “Sponsorship has<br />

a higher dollar value, but the<br />

conversion rate is much higher than<br />

if you were just an exhibitor,” he<br />

explains. “If you sponsor one event<br />

as opposed to exhibiting at two, you<br />

get more exposure in that one event.<br />

Of course, geodiversity also plays a<br />

key role; you can’t compare events<br />

in Dubai to events in Abu Dhabi, for<br />

instance.” Which is why, he says, it’s<br />

crucial for companies to properly<br />

assess what the event has to offer.<br />

“Companies often get event “FOMO”<br />

(fear of missing out) because of the<br />

first binary factor: branding. So, if<br />

they have USD 30,000 to spend in<br />

events, they can spend USD 5,000 to<br />

exhibit at 6 events. That’s fine, each<br />

company has their objectives and<br />

strategy, but there must be a clear<br />

idea of what each event has to offer.<br />

There are scenarios where spending<br />

that USD 30,000 on sponsoring two<br />

or even just one highly relevant<br />

conference in a significant way can<br />

bring in more business and provide<br />

a better ROI.”<br />

Branding, as it relates to events,<br />

can be measured in dollar value, he<br />

says. What many exhibitions do, is<br />

measure how many ads were placed<br />

and how many mentions were used<br />

on social media. These are metrics<br />

for a portfolio of events' success. “In<br />

terms of PR,” he further explained.<br />

“It’s about the number of news<br />

An ear to the ground:<br />

The user experience of cooling<br />

From dealing with cheap fixes to bearing costly consumption, how do tenants and property<br />

owners in the UAE feel about their cooling? Eurovent Middle East shares the accounts of<br />

everyday people and looks at the complex relationships between tenants, landlords and<br />

maintenance companies and their impact on comfort, energy efficiency and IAQ.<br />

articles or TV coverage, that’s<br />

how we measure dollar value by<br />

saying you got USD 350,000 worth<br />

of ads, but you paid USD 8,000, so<br />

companies must remember the<br />

benefits might not always translate<br />

to a company objective metric.”<br />

A reminder of why content and<br />

case studies matter<br />

These issues are further<br />

compounded by the increasing<br />

number of HVAC conferences in the<br />

UAE, overlapping event schedules<br />

and fragmented attendee base<br />

and overall difficulty in standing<br />

out and attracting attention amidst<br />

competition. Against this backdrop<br />

and as a final word, Ebrahimi says<br />

it is important to remember that<br />

content is key for a successful<br />

conference at the end of the day.<br />

The agenda and speaker line-up, he<br />

says, will always be the biggest draw<br />

for people, especially as not enough<br />

emphasis on content and too much<br />

emphasis on sales pitches can be<br />

demotivating for audiences.<br />

Ebrahimi also firmly believes that<br />

case studies are the most effective<br />

tool in the presenters’ toolbox.<br />

“From a sales, marketing, and<br />

even psychological perspective,<br />

case studies are the way to go,” he<br />

says. “The number one thing I say<br />

as a consultant is case studies are<br />

the best type of content because<br />

this is the most effective way to<br />

show why your product or solution<br />

works and how it tangibly helped<br />

someone. Combining this with<br />

good communication – and even<br />

story-telling skills – is how you win<br />

psychologically; if you can highlight<br />

a challenge a past client faced and<br />

tell a success story about how your<br />

solutions helped them, any audience<br />

who is listening and faces the same<br />

challenge will feel like you’re talking<br />

directly to them. Your message will<br />

resonate far more effectively in this<br />

way”.<br />

Ebrahimi says that this is a far more<br />

effective method of persuasion<br />

than simply listing the features<br />

and functions of your products<br />

and solutions, leaving with a final<br />

reminder to “speak more on the<br />

how, and not just the what”.<br />

Mahyar Ebrahimi is an experienced<br />

Over the years, Eurovent Middle<br />

East has advocated for minimum<br />

standards and stronger enforcement<br />

of critical building regulations<br />

in relation to the HVACR sector.<br />

Markus Lattner, Managing Director<br />

of Eurovent Middle East, says,<br />

“From ensuring better equipment<br />

to secure the reliability and energy<br />

efficiency of operations to supporting<br />

training for better maintenance of<br />

installed systems, we, along with<br />

our members, have cultivated strong<br />

partnerships with government<br />

regulators and organisations to<br />

create better pathways and support<br />

the sustainability objectives for the<br />

built environment.”<br />

The objective of the association has<br />

always been to improve the quality of<br />

life of inhabitants aside from working<br />

towards better energy efficiency<br />

and sustainability. This is a critical<br />

topic in a region like the Middle<br />

East where cooling is not a luxury<br />

but a necessity, and in this article,<br />

Eurovent Middle East investigates<br />

the diverse range of personal<br />

experiences that everyday people<br />

have when it comes to their cooling<br />

and ventilation systems and the real<br />

cost behind them.<br />

One such person is Olivier, a tenant<br />

and owner of both new and older<br />

developments. “We bought an<br />

apartment in the Marina, which<br />

had a centralised AC system at the<br />

building level, with a thermostat<br />

in each of the two bedrooms and<br />

one in the living area,” he shared.<br />

“Only the one in the living area had<br />

an automatic function, and I never<br />

could get proper quotes to replace<br />

the ones in the bedroom that had the<br />

fan permanently on or off.” In over 3<br />

years in the apartment, Olivier says<br />

the overall system was very reliable,<br />

and due to it being centralised at the<br />

building level, it cost an average of<br />

AED300/month year-round.<br />

Olivier’s tenanted villa in Jumeirah<br />

Park, however, has been the cause of<br />

more headaches, and more money.<br />

“We have 8 AC units there, and<br />

although we've made some proper<br />

maintenance on ducts, frequent<br />

AC servicing on all units, and even<br />

redone windows sealing, we still<br />

have some humidity and noise<br />

issues,” he shares. “In one of the<br />

bedrooms, we have spent a couple<br />

of thousand (dirhams) on diagnostic<br />

and to rebuild a blower fan. Our<br />

tenants are still experiencing<br />

excessive noise.” Olivier shares that<br />

“well-known companies" wanted<br />

to charge him over AED12,000<br />

to change all the piping without<br />

pinpointing the problem, while<br />

others a couple of hundred just to<br />

investigate further.<br />

At the mercy of the landlord<br />

Maintenance, or even replacement,<br />

of cooling systems, is a problem<br />

many UAE tenants have encountered<br />

at some point or another. Eva is one<br />

such tenant, sharing her experience<br />

campaigning to replace the air<br />

conditioning units in her 3-bedroom<br />

villa in Ras Al Khaimah. “At its peak,<br />

in the heat of summer, we paid AED<br />

3000 a month,” she says. “After the<br />

replacement, our bill was reduced<br />

to AED 1500.” Thankfully, Eva says,<br />

the landlord showed initiative in<br />

trying to procure higher quality units<br />

instead of the cheapest available in<br />

the market.<br />

Landlord responsibility is a critical<br />

topic, and Rafiq, both a tenant and<br />

a landlord for several properties,<br />

believes it’s important for both<br />

parties to clearly understand<br />

their respective responsibilities.<br />

he says. “So, if they want to clean<br />

or fix their ducts, they will need to<br />

invest in that because they use it.”<br />

Olivier echoes this by saying that as<br />

per their tenancy agreement, the<br />

tenants do preventive maintenance<br />

servicing, while he, as the<br />

landlord, takes care of corrective<br />

maintenance and servicing.<br />

Harry is familiar with the hit-ormiss<br />

situation when it comes to<br />

maintenance companies. “I have<br />

had to have my AC units in one of<br />

my old apartments repaired and<br />

eventually replaced completely,”<br />

he says. “Thankfully, the company<br />

that owned the building had its<br />

own FM and HVAC teams, so they<br />

managed the maintenance and<br />

repair processes entirely. I carried<br />

out a regular annual cleaning and<br />

servicing programme with them.<br />

However, I also faced common<br />

issues such as leaking pipes/vents,<br />

condensation build-up, frosting,<br />

and on one particularly memorable<br />

occasion – a faulty bracket that<br />

brought the entire unit through the<br />

false ceiling!”<br />

Reiterating the importance<br />

of investing in skilled and<br />

quality building maintenance is<br />

Gopalakrishnan G, Operations<br />

Director, Emrill, an integrated FM<br />

company, who says that working<br />

with industry-leading FM partners<br />

that understand building operations<br />

and how to manage assets efficiently<br />

is essential to reducing the risk<br />

of breakdowns and extending an<br />

asset’s lifecycle. “Through investing<br />

in the correct maintenance regime<br />

for HVAC assets, you will not only<br />

increase the asset's life but can also<br />

achieve a saving of between 20%<br />

to 30% on energy bills according to<br />

recent studies,” he says. “A wellmaintained<br />

system will also improve<br />

reliability and contribute to lowering<br />

the carbon footprint of a building.”<br />

Finding the right partner<br />

Although the value of proper<br />

maintenance is clear among<br />

property owners themselves, many<br />

find it difficult to find the right<br />

partner. Olivier says, “As an owner,<br />

we now have found a company that<br />

is performing the maintenance<br />

and repairs to the level that we<br />

expect. But this took years and cost<br />

us significant expenses for major<br />

repairs that did not solve the issue<br />

completely, rather only enough<br />

for the maintenance team to deny<br />

support.”<br />

Olivier’s Jumeirah Park villa has<br />

faced recurring problems that seem<br />

hard to diagnose and have been<br />

going on for years, underlining<br />

his frustration with the building<br />

maintenance landscape. “It's<br />

very difficult to find maintenance<br />

companies that would neither do<br />

some dodgy quick fix nor throw<br />

money at the problem by changing<br />

everything,” he says. “Most<br />

companies I have been in contact<br />

with over the years are either<br />

focusing on cheap, quick fixes or<br />

changing everything laughing at<br />

the unprofessionalism of other<br />

companies. In my opinion, both<br />

approaches are wrong, if your<br />

car has a wheel bearing problem,<br />

recommending to change car<br />

doesn't make you a good mechanic it<br />

makes you a good car salesman, and<br />

this is not why I called you. Very few<br />

companies do proper investigation<br />

and address the problem properly<br />

without over-engineering the<br />

solution.”<br />

Eva quickly points out that while<br />

good, reliable landlords or building<br />

managers try to look for quality<br />

HVAC maintenance, they are more<br />

of an exception than a rule, as many<br />

do not fulfil their responsibility.<br />

“Several years back, we moved into<br />

an attractive villa on the surface<br />

level, but on the inside, it was very<br />

badly built,” she recalled. “The<br />

AC systems were badly fitted and<br />

inadequate to cool the villa. The<br />

worst was that we had permanent<br />

black mould in ceilings, and this<br />

was a health hazard because my<br />

husband has asthma. The landlord<br />

would not do anything, even after<br />

multiple complaints. At most, they<br />

would send someone to clean it, but<br />

they didn’t do a very good job. My<br />

husband got an independent person<br />

Gopalakrishnan G<br />

to give a report, and they found that<br />

there were sections missing. They<br />

skimped on corners.”<br />

Gopalakrishnan agrees that it can<br />

be very challenging for tenants in<br />

the UAE to have control over the<br />

maintenance and repair of their<br />

HVAC systems and assets without<br />

their landlord’s support. “This<br />

is because, in most cases, the<br />

landlord owns the HVAC asset and<br />

is responsible for its maintenance<br />

and repair unless stipulated in<br />

the tenancy agreement,” he says.<br />

“For tenants residing in large,<br />

multi-household developments,<br />

the community management<br />

organisation may require a NOC<br />

(no objection certificate) from<br />

the landlord to allow work to<br />

commence. Property owners may<br />

also face challenges when it comes<br />

to property modifications, as they<br />

are required to take approval<br />

from the developer before any<br />

modification work occurs. These<br />

rules and regulations may vary<br />

between different communities.<br />

However, compliance with<br />

community rules and regulations<br />

usually forms part of property and<br />

tenancy agreements in the UAE.”<br />

Harry admits that in his experience,<br />

it’s been quite difficult to exercise<br />

greater control over the cooling<br />

units and equipment as their<br />

ownership tends to be quite<br />

complicated. “For example, in my<br />

previous apartments, the building<br />

was owned by a private developer,<br />

but the cooling units were installed<br />

and operated by a separate, semigovernment-backed<br />

entity, who<br />

exercised complete authority over<br />

the equipment, he says. “While<br />

maintenance and repairs were<br />

allowed within the apartments<br />

themselves, any equipment in public<br />

areas, such as hallways, was the<br />

responsibility of the provider. As<br />

such, it was impossible to establish<br />

any autonomy over saving on energy<br />

costs. But, this would absolutely be<br />

something I’d like to have control<br />

over.”<br />

What do tenants want?<br />

Gopalakrishnan says it is important<br />

to note that any changes or<br />

modifications made to the HVAC<br />

system without the landlord's<br />

consent could be considered a<br />

breach of the tenancy agreement.<br />

“Therefore, the landlord may have<br />

the right to take legal action against<br />

the tenant,” he says. “However,<br />

by creating and maintaining<br />

beneficial stakeholder relationships<br />

and working with community<br />

management and landlords, many<br />

challenges can be overcome and<br />

often avoided.”<br />

In the event that the relationship<br />

between landlord and owner is<br />

too fragmented, tenants often find<br />

themselves on the losing end,<br />

says Eva who has had to face a<br />

cumbersome legal battle with her<br />

old landlord. “We told him that we<br />

would not pay him in advance if he<br />

didn’t fulfil their side of the bargain<br />

of fixing the issues such as the black<br />

mould,” she says, “He was furious,<br />

and he took us to local court. It’s so<br />

stressful because you’re only asking<br />

for the basics.” Even if landlords<br />

make an effort, Eva says, tenants<br />

don’t have power over the quality of<br />

maintenance. “Many of them choose<br />

maintenance people they send based<br />

on cost, not on the quality,” she says.<br />

“They work with the cheapest guys,<br />

not real tradesmen.”<br />

Currently, Eva says that she does<br />

not feel there is an existing body<br />

she can go to mediate the problems<br />

she has faced. “Many people have<br />

a problem with their landlords and<br />

lack of clarity on what rights they<br />

are afforded, and there are those<br />

that fight back that find themselves<br />

being evicted because landlords<br />

know they can always find someone<br />

else to rent,” she says. “RERA<br />

is responsible for ensuring they<br />

enforce aspects of the rent, but<br />

there isn’t a particular body you<br />

can go to if you have a query or<br />

difficulty about something related<br />

to maintenance of buildings.” Eva<br />

hopes that one day there could be<br />

an official body they could go to if<br />

landlords are not doing their part in<br />

the case of repairs.<br />

Markus Lattner<br />

For Markus Lattner, Managing<br />

Director of Eurovent Middle East,<br />

these accounts demonstrate the<br />

critical role of quality products and<br />

skilled technicians. “Many times,<br />

manufacturers, brands, are blamed<br />

for bad user experience, while the<br />

problem solely comes from bad<br />

installation and cheap, unskilled<br />

labour.” He underlines the need for<br />

better requirements, driven either<br />

by market mechanisms, regulatory<br />

intervention, or both. “We need<br />

minimum qualification requirements<br />

throughout the supply and value<br />

chain.”<br />

Lattner stresses, “Bad user<br />

experience is ultimately a different<br />

indication that HVAC systems don’t<br />

work as projected, and that always<br />

means that we waste a lot of energy,<br />

people’s energy in fighting bad<br />

installation and significant amounts<br />

of electricity. It's time to clarify<br />

responsibilities. Energy certificates<br />

for buildings, minimum qualification<br />

requirements for technicians, and a<br />

code of conduct for FM companies<br />

are examples of tools that can be<br />

used by authorities in their efforts<br />

to cultivate more sustainable<br />

INSIGHTS<br />

Regulatory developments in the GCC<br />

Regulatory bodies in the region are back in full steam to revise existing regulations for air<br />

conditioners after two more quiet years owed to the pandemic. Markus Lattner, Managing<br />

Director of Eurovent Middle East, shares insights into discussions, developments and the<br />

association’s positions.<br />

Currently, regulations for both small<br />

and large-capacity air conditioners<br />

(GSO 2630, SASO 2663, SASO 2874,<br />

UAE.S 5010-1, UAE.S 5010-5) are<br />

under revision by the respective<br />

bodies and technical committees,<br />

which are working in full steam. To<br />

fully understand the implications<br />

of regulatory developments, it is<br />

important to dissect a technical<br />

regulation into its major parts.<br />

Normative References<br />

For one, normative references<br />

ultimately determine under which<br />

standards and test methods a<br />

product is allowed to enter a<br />

market. The references commonly<br />

used internationally in the HVAC<br />

sector are ISO, EN and ANSI<br />

standards. The decision of which<br />

one specifically to apply is a<br />

challenging one. In this globalised<br />

time, products and components<br />

are manufactured and shipped<br />

around the world. For instance,<br />

most air conditioning equipment for<br />

IT cooling sold in the Middle East<br />

is produced by European factories.<br />

However, that doesn’t mean they<br />

are European companies.<br />

Most of the big international players<br />

from Asia, Europe and America have<br />

production lines all over the globe<br />

and produce for local and regional<br />

markets, but also beyond. The<br />

industry is not divided along political<br />

borders but rather bound to what<br />

the markets demand. Inclusivity<br />

in terms of normative references<br />

thus is preferred by manufacturers<br />

to allow flexibility in regards to<br />

their supply chain. As long as the<br />

standards referenced reflect the<br />

latest versions and are comparable<br />

in terms of testing methodology and<br />

results, it provides much-needed<br />

fairness in market access.<br />

For some products, ISO standards<br />

have been agreed to by most<br />

of the players and became the<br />

preferred option, while for other<br />

products EN or ANSI standards still<br />

prevail, mostly due to weaker or<br />

lacking ISO coverage. Additionally,<br />

environmental conditions<br />

demand regional adjustments of<br />

international standards to reflect<br />

the increased requirements for<br />

energy performance and durabilites<br />

in the region.<br />

Normative references also have<br />

significant impact on market<br />

surveillance and regulatory<br />

Markus Lattner<br />

compliance. In itself a crucial<br />

point for a closer look, which I<br />

will get back to in a bit. Overall,<br />

it is important to address such<br />

references on a product-by-product<br />

basis, to clearly understand the<br />

origins of equipment and avoid<br />

interruptions of supply chains.<br />

Minimum energy performance<br />

requirements<br />

Minimum energy performance<br />

requirements (MEPS) are core and<br />

purpose of such regulations. They<br />

define minimum efficiency values<br />

for products in the market and are<br />

the basis of any energy labelling. In<br />

the current revisions, authorities<br />

are set to change from EER to SEER<br />

(Seasonal Efficiency) calculations.<br />

The industry fully supports this<br />

transition as SEER provides a more<br />

realistic calculation of energy<br />

consumption, especially with more<br />

variable speed technology in place.<br />

As SEER is based on weather<br />

bins, it can be fully adjusted to<br />

local requirements. Eurovent has<br />

looked at various weather bins in<br />

the region and concluded, from<br />

sample calculations, that the<br />

differences among weather bins<br />

of Saudi Arabia, Kuwait and UAE<br />

lead to only marginally different<br />

SEER values, opening the door<br />

for a regional unified weather bin<br />

and harmonisation of regulations<br />

across the GCC, even for Kuwait.<br />

In terms of defining minimum<br />

requirements, the discussion is<br />

ongoing. While split units have<br />

taken a leap with the inverter<br />

technology, the region still<br />

holds on to window-type ACs,<br />

widening the possible range of<br />

energy efficiency labels. Here the<br />

question stands if an energy label<br />

which starts at a SEER value of<br />

8 and rises in steps up to above<br />

19 is really effective. After all, it<br />

would do little to push the market<br />

to better performances.<br />

As an industry association, we<br />

believe a bolder push to raise<br />

efficiency levels is possible.<br />

Not taking any side for or<br />

against technology, but some<br />

manufacturers have shown<br />

that also window types can be<br />

fitted with inverters, improving<br />

their efficiency significantly over<br />

non-inverters. The technology<br />

is freely available and would<br />

allow also local producers to<br />

adjust. Increasing the minimum<br />

requirements would therefore be<br />

feasible. But this, ultimately, is a<br />

decision the government has to<br />

take.<br />

Compliance<br />

Compliance requirements make the<br />

third major part of a regulation and<br />

the part which can inflict the highest<br />

costs on suppliers. The Middle<br />

East depends a lot on pre-market<br />

testing of imported products. This<br />

means that before a unit is shipped,<br />

manufacturers must apply, register<br />

and get their products approved by<br />

the authorities, or else shipments<br />

would be denied entry into the<br />

country. This adds substantial<br />

administrative, testing, and<br />

certification costs.<br />

In a price-sensitive and highly<br />

competitive environment, one can<br />

imagine that the interpretation<br />

and execution of regulatory<br />

requirements can make a huge<br />

difference. The industry needs a<br />

fair and level playing market. Every<br />

manufacturer wants to ensure<br />

that his competitor follows the<br />

same rules. Thus, ensuring that all<br />

products are fully in line with the<br />

laws and regulations is absolutely<br />

critical.<br />

Owing to the lack of local testing<br />

capabilities, market surveillance<br />

is not a strong point in the region.<br />

Furthermore, it only really works<br />

for consumer goods, not custommade,<br />

larger equipment. This<br />

aspect underlines the advantage of<br />

independent third party certification<br />

as offered by organisations<br />

like AHRI and Eurovent. Both<br />

have established certification<br />

programmes in cooperation with the<br />

industry, allowing an independent,<br />

objective and neutral certification<br />

of product performances, which a<br />

majority of manufacturers already<br />

use.<br />

These certifications are requested<br />

by planners and consultants<br />

and are, therefore, already in<br />

wide use. And such certificates<br />

are also in place for customised<br />

equipment, which otherwise<br />

wouldn’t be possible to assess<br />

if not for a unit by unit testing,<br />

for which neither enough testing<br />

capacities exist, nor would it<br />

make any financial sense. So, why<br />

are we not using these already<br />

existing certifications to prove<br />

compliance with regulations?<br />

Eurovent for instance, has already<br />

adapted its certification to Middle<br />

East requirements, reflecting<br />

the need for T3 conditions in<br />

testing methods. It would allow<br />

governments to bring up to 80%<br />

of the market under regular<br />

surveillance, as both AHRI and<br />

Eurovent are based on recurrent<br />

testing, and allows that limited<br />

budgets for market surveillance<br />

can be used to focus on noncertified<br />

products.<br />

It also would relieve<br />

manufacturers from the<br />

requirement of having their<br />

products tested again and<br />

again, with no added benefits.<br />

All it would need is a directive<br />

to notifying bodies that such<br />

certificates are recognised as<br />

proof of equipment performance,<br />

based on which these bodies are<br />

allowed to establish compliance.<br />

It again requires flexibility in the<br />

normative references to make room<br />

for ANSI and EN standards and<br />

the respective testing standards of<br />

Eurovent and AHRI.<br />

Country-specific requirements and<br />

harmonisation<br />

Other critical aspects of regulations<br />

usually refer to country-specific<br />

requirements, which equally can<br />

become very costly. Kuwait’s<br />

understandable insistence on<br />

specifying T4 conditions or the<br />

UAE requirement for a 20-degree<br />

cut-off limit for ACs, or the need<br />

to accommodate varying voltage<br />

declarations on name plates and<br />

country-specific energy labels,<br />

are making life difficult for<br />

manufacturers.<br />

Harmonisation would substantially<br />

reduce air conditioning costs in<br />

the region while increasing the<br />

number of available options in<br />

the market. The T4 requirement<br />

in Kuwait is prohibitive for many<br />

suppliers, as the low market volume<br />

renders investment in extra testing<br />

and certification not feasible. The<br />

20-degree temperature limitation,<br />

while in itself a very worthwhile and<br />

valuable political consideration,<br />

brings about a number of concerns.<br />

As only applied in the UAE, it<br />

requires extra stockholding<br />

and costly processes to fulfil.<br />

Additionally, its effectiveness in<br />

achieving the original intention<br />

of implementation is doubtful, as<br />

Eurovent Middle East has outlined<br />

in another article. (See the article<br />

“Setting the Limits”)<br />

Harmonisation is the top priority<br />

for the industry and could unlock<br />

more energy-saving potential<br />

through regulatory intervention as<br />

is currently achieved in the bespoke<br />

regulations. It would reduce unit<br />

prices considerably making room<br />

for more ambitious performance<br />

requirements. After all, what is the<br />

point of different requirements in<br />

each GCC country if ultimately the<br />

products sold are exactly the same?<br />

Stakeholding – the importance of<br />

working together<br />

Eurovent Middle East is involved in<br />

all current technical committees<br />

providing inputs by the industry.<br />

Within several open meetings in<br />

the past months, we called upon<br />

members and non-members to<br />

provide us with their comments<br />

and we have established the main<br />

positions of the industry, which<br />

we will bring forward to each<br />

committee. But if the industry<br />

wants to see more harmonisation<br />

and be heard by regulators, it is<br />

crucial to show support and work<br />

together.<br />

Stakeholding processes are<br />

complicated and take their time.<br />

Equally, authorities need to<br />

understand that due process is<br />

vital to better regulations and that<br />

an industry association needs<br />

time to discuss and consent on<br />

positions with manufacturers.<br />

There is room for improvement on<br />

either side, but overall I see many<br />

steps in the right direction. It is a<br />

long way to go, but at least we are<br />

on the right road.<br />

Uncovering the savings from<br />

certified cooling towers<br />

Emmanuel Timothy, Senior Project Engineer, BAC Middle East L.L.C. and Rafael Van Eijcken,<br />

General Manager, BAC Middle East L.L.C., write on the actual savings that can be unlocked<br />

from opting for Eurovent or CTI certified cooling towers compared to cutting cost with<br />

undersized cooling towers…<br />

Although cost is a critical<br />

consideration for customers, there<br />

is a need to encourage a more<br />

holistic procurement strategy that<br />

considers long-term savings over<br />

first-time payments. The initial cost<br />

is not the best, nor should it be the<br />

only measurement of the product's<br />

true value, especially when it<br />

comes to critical HVAC equipment<br />

such as cooling towers, where the<br />

performance and operation will be<br />

responsible for the majority of the<br />

total cost in the long term.<br />

This issue becomes very applicable<br />

and visible when choosing between<br />

certified or non-certified equipment.<br />

Certified equipment differs from<br />

non-certified equipment not only in<br />

terms of the initial purchase price,<br />

with the former typically being more<br />

expensive, but also in terms of size,<br />

weight, performance, and other<br />

aspects. The reluctance of some<br />

stakeholders to invest in Eurovent<br />

or CTI-certified cooling towers is<br />

primarily due to the need for more<br />

awareness and understanding of<br />

the value it offers to their bottom<br />

line in the long term. However,<br />

having a clear understanding of<br />

the importance of certification and<br />

the available supporting tools for<br />

customers to verify and choose<br />

certified models would help prevent<br />

the selection of incorrect cooling<br />

towers, which will have severe<br />

consequences due to performance<br />

issues in the installed site.<br />

To provide background, Eurovent<br />

Certified Performance (ECP)<br />

Programs' main aim is to promote<br />

fair competition and provide<br />

customers with reliable information<br />

about the performance of equipment<br />

in the market. To achieve this,<br />

manufacturers' claims regarding<br />

product ratings are verified through<br />

independent testing of randomly<br />

selected production models in<br />

external laboratories. The objective<br />

is to ensure that each certification<br />

program is effective and trustworthy<br />

enough for the market to recognise<br />

and demand ECP-certified<br />

equipment when making investment<br />

decisions. Eurovent, in collaboration<br />

TECHNICAL ARTICLE<br />

Rafael Van Eijcken<br />

Institute (CTI), has developed a<br />

certification program specifically for<br />

the thermal performance of factoryassembled<br />

open, and closed-circuit<br />

cooling towers. These program<br />

models consist of individual units<br />

with published thermal rating<br />

capacities and associated input fan<br />

power levels.<br />

Looking at the numbers<br />

Let us consider a typical example<br />

in the Middle East of an HVAC<br />

application that operates year-round<br />

with a load variation from 100%<br />

in summer to 75% in winter. The<br />

summer condition to cool 100 LPS<br />

from 40°C to 35°C at an ambient wet<br />

bulb temperature (WBT) of 32°C. In<br />

this case, the cooling capacity to be<br />

rejected would be 2093 KW.<br />

For this scenario, the selected<br />

cooling tower, which we can refer<br />

to as Cooling Tower A (CT-A), will<br />

have a length of 2585 mm, 5500<br />

mm wide and 3653 mm high with<br />

29 KW absorbed fan power and a 30<br />

KW installed fan motor. The overall<br />

sound power level of CT-A would be<br />

104 dB(A).<br />

Now, let us consider an undersized<br />

model Cooling Tower B (CT-B),<br />

which would only deliver 85% but<br />

with a lower initial cost than CT-A.<br />

Typically, this unit would be 15%<br />

smaller in physical size or have<br />

the same size as CT-A but with an<br />

absorbed fan power of only 20.1 KW<br />

Emmanuel Timothy<br />

with a 22 KW installed fan motor.<br />

The overall sound power level of<br />

the CT-B would be 102 dB(A).<br />

For 2093 KW, which has to be<br />

dissipated at WBT 32°C, CT-B will<br />

supply a 1.35°C warmer outlet<br />

than designed. Or it will deliver<br />

the design temperatures up to a<br />

WBT of 30.79°C only.<br />

For projects where undersized<br />

cooling towers are installed, which<br />

are also typically non-certified<br />

cooling towers, when customers<br />

face a shortage in capacity<br />

and contact that cooling tower<br />

manufacturer about the problems<br />

faced on site, the response will<br />

typically be that the supplied<br />

cooling tower is “correctly<br />

sized” and that the issue is most<br />

probably related to poor operation<br />

and maintenance. This risk is<br />

taken by some manufacturers in<br />

the belief that the customers will<br />

not make an effort to request and/<br />

or verify third-party certification<br />

documents, as their main priority<br />

is choosing a system with the<br />

lowest initial cost. Initially, the<br />

problems caused by an undersized<br />

cooling tower unit might be<br />

minimal until the project requires<br />

its full cooling load which may<br />

take several years. In time,<br />

however, the problem of capacity<br />

shortage will be aggravated and<br />

create serious problems onsite.<br />

Although the customer may be<br />

misled by small power savings<br />

on the fan motor KW for CT-B<br />

compared to CT-A, they may not<br />

be aware that such an undersized<br />

cooling tower will trigger extra<br />

work on the chiller by increased<br />

compressor lift linked to the 1.35°C<br />

warmer water supplied to the chiller<br />

by CT-B. This increased compressor<br />

work increases the chiller power<br />

consumption significantly during a<br />

year-round operation by more than<br />

6%. With the chiller compressor<br />

motor being a multiple of the CT<br />

fan motor, this situation causes<br />

significantly higher operational<br />

costs for the customer.<br />

Let us also look at the annual<br />

economic impact the customer<br />

will face with CT-A and CT-B if<br />

both cooling towers use variable<br />

frequency drives and run with a<br />

water concentration factor of 5<br />

cycles.<br />

The fan kWh requirement-based<br />

year-round operation for CT-A will<br />

be 55,540 kWh, and for CT-B, it<br />

will be only 50,800 kWh. However,<br />

looking at the electrical energy<br />

needed for the chiller, for CT-A, we<br />

need 1,114360 kWh, but for CT-B,<br />

the chiller requirement goes up to<br />

1,178,700 kWh, which is 6% more.<br />

Therefore, by adding the chiller and<br />

fan kWh the CT-B system still needs<br />

5% more electrical energy annually.<br />

A typical AED 0.38 fils/kWh cost will<br />

represent an annual operating cost<br />

of AED 22,648.00.<br />

In addition, CT-B will have more<br />

water consumption, as the chiller<br />

will need to work harder, and<br />

therefore more waste energy is<br />

dissipated, resulting in more water<br />

evaporating. Ultimately, the CT-B<br />

water consumption will be 300 m3<br />

[65,991.00 Imperial Gals] water<br />

more than CT-A. Considering the<br />

water rate at AED 4.6 fils/IG (plus<br />

the sewerage charges) this will add<br />

approximately another AED 4,500.00<br />

per year.<br />

Below is a chart illustrating the<br />

additional cost vs energy and water<br />

costs with a 3% year-on-inflation<br />

rate price increase.<br />

The total operating cost difference<br />

for water and electricity for<br />

the system with CT-B will be<br />

AED 27,148.00. This number is<br />

typically near to half of the first<br />

cost difference with CT-A. From<br />

this, it is clear that a small price<br />

advantage for CT-B melts away when<br />

considering energy and water costs<br />

Keep in mind<br />

Thus, it is essential to remember<br />

that value for money does not just<br />

come by looking at the first cost and<br />

mindlessly accepting manufacturer<br />

documents with self-declared<br />

thermal performance. A customer<br />

must be able to challenge such<br />

manufacturer declarations by<br />

questioning whether the thermal<br />

performance is Eurovent/CTI<br />

certified or insist on a performance<br />

field test (acceptance test)<br />

according to the Eurovent/CTI<br />

standards to confirm or verify the<br />

declared thermal performance.<br />

Only by insisting on a field<br />

performance test carried out by<br />

certified testing agencies, even<br />

with the additional cost, will the<br />

customer determine whether the<br />

cooling tower can provide the listed<br />

performance. However, suppose<br />

the results lead to a failed test. In<br />

that case, the customer’s misery<br />

will just begin, as this often leads to<br />

many unpleasant discussions with<br />

the manufacturer, often with no final<br />

resolution. Selecting a cooling tower<br />

which has Eurovent / CTI Certified<br />

Performance via either the third<br />

party or internal lab testing ensures<br />

the buyer before the purchase that<br />

they will not have higher operating<br />

costs due to underperformance.<br />

Certified thermal performance<br />

testing removes risk towards<br />

system economics and removes<br />

the guesswork. It also removes the<br />

problems of litigation, penalties and<br />

compensation should an already<br />

purchased product be found to<br />

underperform because it’s too late<br />

by then.<br />

Remember to look for the Eurovent<br />

/ CTI Certified Performance mark<br />

to ensure optimal cooling tower<br />

selection. Eurovent includes yearly<br />

factory certification conformity<br />

audits of the Cooling Tower<br />

manufacturer. At the end of the<br />

day, purchasing a Eurovent / CTI-<br />

Certified model ensures that the<br />

cooling tower will perform as<br />

specified. In all instances of thermal<br />

certification, the purchased model,<br />

or a model within the same line, will<br />

have been thoroughly inspected and<br />

tested by a Eurovent / CTI-licensed<br />

testing agency, and customers can<br />

rest assured that their system will<br />

operate as intended.<br />

MARKET OUTLOOK<br />

Dubai's Construction Boom:<br />

A Resurgence Fueling<br />

Opportunities<br />

By BNC Network<br />

Here are three key themes worth<br />

exploring for HVAC companies<br />

planning their strategy for the region:<br />

The first is the resurgence of Dubai,<br />

the second is sustainable construction,<br />

and the third is KSA’s ambition to be<br />

a leader in all spheres in the years<br />

ahead. We’ll touch upon each of these<br />

briefly along with some key stats.<br />

The Resurgence of Dubai<br />

The sharp decline in the size of the<br />

Dubai construction market post the<br />

expo was expected but so was an<br />

announcement of what would come<br />

next. The pandemic and global<br />

instability have delayed some of<br />

these plans, but Dubai is back and<br />

firing on all cylinders. In the last<br />

5 months, there have been 149<br />

contract awards worth USD 8.5<br />

billion in Dubai alone and there are<br />

several more expected to follow.<br />

Add to this an increase in activity<br />

in Abu Dhabi and cornerstone<br />

projects such as the USD 3.9 billion<br />

Wynn Resort in Ras Al Khaimah<br />

and you have the makings of a new<br />

construction boom.<br />

Contract Awards - UAE:<br />

Sustainable Construction<br />

With COP 28 around the corner,<br />

there is a fresh impetus to drive<br />

sustainability in construction.<br />

While the big move is the energy<br />

transition from fossil fuels to<br />

renewable sources, the<br />

construction sector is a major<br />

contributor to carbon emissions<br />

and has a key role to play. While<br />

there is growing interest in LEED<br />

certification and other standards<br />

that would tout the sustainability<br />

of the project, there are also more<br />

grassroots-level discussions<br />

underway to find practical solutions<br />

to save energy and water consumed<br />

by HVAC systems, which are one of<br />

the biggest energy consumers.<br />

This is an opportune time to connect<br />

directly with project owners who are<br />

now increasingly open to listening to<br />

ideas and learning about products<br />

that would reduce the lifecycle<br />

cost of the projects that they are<br />

creating.<br />

KSA: A whiteboard for new<br />

solutions<br />

KSA does not want to be fantastical<br />

just in terms of tourism, it wants<br />

to be a market leader in several<br />

spheres - the foremost of these is<br />

construction given the hundreds of<br />

billions of dollars that the country<br />

is committing to its giga-projects.<br />

While announcements of major<br />

projects have continued this year,<br />

there has also been an uptick in<br />

contract awards which will translate<br />

into tangible and significant work for<br />

HVAC suppliers in 2024 and beyond.<br />

Awards & Announcements - Saudi<br />

Arabia<br />

KSA’s ambition to lead lends itself<br />

well as a virgin test site for every<br />

supplier who has a magical new<br />

transformative solution that the<br />

market was not willing to pay for<br />

in the past and for commoditized<br />

products it has the volume to offer<br />

through the massive developments<br />

that are underways through the<br />

housing program being orchestrated<br />

by Roshn.<br />

In closing, a two-pronged KSA-UAE<br />

sustainability enablement strategy<br />

is the recipe for success that your<br />

Boards of Directors will probably be<br />

appreciative of at your next board<br />

presentation.<br />
