ast month, I went into considerable detail on the extensive editorial campaign Climate Control Middle East initiated on the state of the MEP consultancy and contracting disciplines, which began by dissecting the issues reportedly preventing them from offering optimal performance.

The culmination of a certain stage of the campaign will be The Consultant Contractor Conference, on September 18 and 19, 2017. It will see MEP consultants and contractors, general consultants and contractors, government officials, master developers, developers, building owners and technology-solutions providers gather on a neutral platform for a discussion on the same issues but in a manner that only a conference setting allows, including instant feedback and possible resolution – or at least the groundwork towards that.

One of the aims of the conference will be to open up channels of communication, because most of the conflicts avowedly owe their origin to a general lacuna in fully understanding and appreciating one another’s point of view. The specific issues could be related to the way contracts are drafted and the manner in which they are interpreted, leading to payment delays.

Further, during one of the earlier discussions in the campaign, MEP consultants and MEP contractors specifically raised the point of a greater scope for regulators and enforcement agencies than the current one, which to a great extent focuses on the equipment side of things, including on energy efficiency, air quality and fire safety. For instance, they suggested that as a business-enabling measure, regulators consider establishing an escrow account for general contractors. Such a step, they said, would ensure that the funds allocated to a particular project were used for the project alone, thus guaranteeing that all the stakeholders down the chain were paid on time. Yet another suggestion of theirs was to set up an evaluation and certification framework, similar to the one established by Dubai’s Knowledge and Human Development Authority, to measure and report the performance of schools in the emirate. The merit-based framework, they said, could apply to all consultants and contractors and would help investors identify the best among them, when it came time to select resources and expertise for any given project. The positive pressure the framework would exert, they added, would compel the consultants and contractors to raise their game and, from a big picture point of view, usher in greater market maturity

New silicon-based heat insulation panel, with thermal conductivity (λ) of just 0.019 W/mK and incorporated with ‘core hydrophobisation’ technology, which makes the entire pore structure – and not just the surface – water repellant, is being presented as a solution for the construction industry, additionally because it reportedly is not susceptible to mould and its mineral-based raw materials offer high fire-retardant properties

hen it comes to unused potential for saving energy, buildings can’t be beat: They are responsible for 28% of the world’s energy consumption, a figure that rises to 45%, when only Western countries are taken into consideration. According to the German Environmental Agency (UBA), an energy-retrofit programme can reduce a building’s primary energy demand by up to 90%. The European Union (EU) has responded by strengthening its directives for the overall energy efficiency of buildings: Starting from 2021, for instance, all new buildings in the EU are to be constructed to meet virtually the same standards as zero-energy buildings.

These buildings should produce electricity in an amount corresponding to their energy consumption.

Given the established fact that good thermal insulation is a key factor in making buildings more efficient, growing demand for building efficiency is resulting in thicker and thicker insulating materials. However, space is particularly limited and expensive in city centres, and fire-safety standards are high.

For this reason, architects are on the lookout for lean solutions that can meet the twin demands, while leaving as much room as possible for creative design.

The recognition of the trend has given rise to a silicon-based heat insulation panel, made of synthetic, amorphous silica. Its thermal conductivity (λ) of just 0.019 W/ mK makes it by definition a super-insulator, performing even better than air at rest, which has a λ value of roughly 0.025 W/mK. This means that the insulation panel can be up to 50% thinner than conventional mineral insulating materials and yet achieve the same effect.

In addition to having super-insulating properties, the panel is categorised as a Class A building material (non-flammable), which presents quite an unbeatable combination. What makes this possible are the mineral nature and the fine porous structure of silica. We have long known that a form of synthetic, amorphous silica is an established first-class insulating material for radiant heaters, where the temperature of the heating coils can reach several hundred degrees Celsius. A layer of the silica, up to a maximum of only about two centimetres in thickness below the stovetop, absorbs the heat to the point where electric cables can be placed, nearby.

The high-tech insulating material is hydrophilic, however. If it comes into contact with water its inner adhesive forces become so powerful that they can destroy the fine porous structure. When this happens, the material not only changes its macroscopic form – it also loses its excellent insulating properties, which is why the

construction industry has long resisted its use as an insulating material.

The breakthrough to solve the challenge posed by water came in the form of a new technology called ‘core hydrophobisation’, which makes the entire pore structure – and not just the surface – water repellant. As a result, water vapour can diffuse through the material without destroying the structure or condensing inside it. And that paved the way for its use in the construction industry.

Plus, thanks to core hydrophobisation, the new insulating material is not susceptible to mould, which eliminates the need for fungicides and biocides. The fact that it is based on mineral raw materials not only explains its strong fire-retardant properties but also emphasises the fact that unlike other types of insulation, it is recyclable. If preferred, it can also be easily disposed of as part of normal construction waste – a cost benefit in the construction industry, which always has its eye on the bottom line.

EFFECTIVELY SUPPRESSES HEAT TRANSFER There are three ways that undesirable heat conductivity can arise in insulation: Solidstate thermal conductivity, heat transfer via gases (which is inhibited, for instance, by the vacuum in multi-glazed windows), and heat transfer via infrared radiation.

The insulation material effectively limits thermal conductivity and heat transfer.

The solid-state matrix of the silica used is specially treated in such a way that the contact surface – and, thus, the transfer paths between individual solid particles – is kept as small as possible, minimising thermal conductivity. In addition, the very tiny pore spaces limit the energy transferred by gaseous conduction. Thermal radiation doesn't stand a chance with the insulation panel, either.

The material and its fine pore structure confer a second advantage: Its thermal conductivity, unlike that of traditional insulating materials, is almost not

temperature-dependent. As a result, the new insulation panel not only prevents the interior from cooling during the winter, but it also keeps it from heating up in the summer, when building exteriors can easily reach temperatures of up to 80 degrees C. This pays off especially in buildings made of lightweight panels. Here, rooms easily become overheated, because the shade from blinds alone is not enough.

STRENGTH IN INDOOR ENVIRONMENT AND FIRE PROTECTION The reason why the thermal conductivity of the new insulation panel is almost not temperature-dependent is its favourable temperature-amplitude ratio – a complex interplay of specific storage capacity, density and thermal conductivity. The ratio describes the phase shift in the temperature maxima, observed when heat is transferred through an external wall. Studies conducted by the Bavarian Center for Applied Energy Research (ZAE), in Würzburg, Germany, have shown that in walls insulated with the insulation panel, heat takes eight to 12 hours to reach the interior wall – in other words, not until nighttime, at which point the air outside has cooled, and ventilation from windows provides a pleasant ambient temperature.

Since the time of emergence of the new panel, the team of developers of the panel has taken an intense look at the needs of customers and end consumers. Using numerous reference objects, the team members have been able to demonstrate its performance.

The most recent example can be found in the historic centre of Düsseldorf, where the team insulated the ceilings of the basement and the underground parking garage of a historical landmark building, to which a modern extension had been added. The structure of the underground garage and the sprinkler system of the building were to be preserved to keep costs down, even though they left little space for thermal insulation or fire-protection. The structure of the modern annex needed to be updated, accordingly.

The project played to the strengths of the new insulation panel, which offers strong fire-retardant and thermal insulation properties for the basement ceiling while protecting the sprinkler system from freezing temperatures – all in a very little space. The insulating layer is only 40 mm thick, whereas traditional insulation would have required a much thicker layer.

▶ HTE Plant Coatings by Evonik SUITABLE FOR INSIDE AND OUTSIDE THE BUILDING ENVELOPE

The team of developers is currently working on adjusting the granulation process for silica in order to optimise density, pore size and mechanical stability

The new insulation panel is suitable for cavity insulation for load-bearing, external walls, for interior insulation, for insulating rainscreen cladding and for concrete sandwich elements. Within the facade itself, the insulation can be combined with ceramic tiles and with elements made of glass, metal or concrete – even with PLEXIGLAS. In quite a path-breaking move, the combination of the insulation panel and PLEXIGLAS has been used for building exteriors. Thanks to its heat transfer coefficient of 0.15 W/m²·K, the panel only has to be 12 cm thick to achieve passive building standards, using 90% less heating energy than a traditional building.

MORE FREEDOM FOR COMPONENT GEOMETRY Research work on the new insulation panel hasn’t stopped there. In order to free up more options for component geometry, there are plans to offer the material in granulate form. Their ability to fill cavities means that granulates can be used for insulating reactors or boilers, for example.

For this to work, the granulate must be mechanically stable, and it must be possible to control its pore structure, as

this has a critical impact on its thermal insulation properties – if the structure is destroyed by stirring or shaking, the insulating properties will be lost. The team of developers is currently working on adjusting the granulation process for silica in order to optimise density, pore size and mechanical stability, while maximising cost effectiveness.

Overcoming the hurdle would also clear the way for its use as insulating filler for mineral-based construction products and coatings. This, in turn, would open up the possibility of manufacturing safe-touch and thermal insulation coatings, which differ in terms of thickness. For safe-touch coatings, just a few millimetres are all it takes to prevent a hot surface from damaging skin on contact. Industrial occupational safety would be one potential application.

Thermal insulation coatings take this a step further. Unlike safe-touch coatings, they prevent energy from being lost in the form of heat transferred to the surrounding air. This, however, requires thicker coatings of several centimetres.

While these developments are far from being ready for the market, the team behind the development of the panel has already sent granulate samples to an initial group of customers.

The move marks a return to familiar work habits – looking to the needs of the market, even at an early stage in the process, and incorporating customer feedback into the ongoing development process.

he Greek philosopher, Heraclitus rightly asserted, “There is nothing permanent except change." As construction projects evolve from the drawing board to the stage of delivery, changes, in the form of variations, direct the actual path of the project. Industry insiders have affirmed that there is always a significant difference between what was conceptualised and designed, and the closeout of the project.

Amid the exponential growth of the construction industry in the Middle East, a concretised road is yet to be established to deal with the dramatics of variations. One of the big questions that needs to be answered is, ‘Who should win the conflict among the contractor, consultant and developer, when variations occur in a project?’

THE USUAL SUSPECTS

Dr Ramiz Babus'Haq

Sameer Daoud

August 2017

The performance of a construction project can be fully optimised and the goals achieved if the work cycle invariably progresses consistently and strictly within the set timeframe and drafted budget.

Unfortunately, in most scenarios, this remains in theory, because most construction projects are blighted by variations. The usual suspects that drive variations range from design discrepancies to unplanned changes during the construction phase, often induced by ignorance of domain knowledge.

But who really takes the blame? V.S Chandra Shekar Reddy, CEO of Elemec Electromechanical Contracting, says: “There is a vertical split between the developer, the project management team, the consultant and the engineer, and all pinpoint the blame on the contractor for causing variations.

There is a serious lack of taking responsibility when a variation is caused because of the design flaw, and the contractor has to bear the cost. Very few consultants actually take the responsibility.”

In some cases, the project managers sound the ‘bugle of urgency’, and unwarranted pressure is exerted on the contractors by demanding quick completion of the work. As Reddy puts it: “In order to please the client, the project management team exerts unnecessary pressure on the contractor by demanding an undue urgency to complete the work. Sometimes, the contractor succumbs to this pressure and deviates from the master plan and causes a variation to occur.”

IMPACT OF VARIATIONS

Variations can have a negative as well as a positive impact on a construction project, but more often than not, they affect the time frame of the project and accelerate costs. Explaining the impact of any variation, Dr Ramiz Babus’Haq, Deputy General Manager at Hydro Engineering Consultants, says: “The magnitude of any variation can range from thousands to millions of dollars, depending on the type of variation and the amount of money invested in the overall project, even if it is a positive variation. It has a domino effect on the project, and it affects the time frame and the overall cost of the project and, at times, even the quality.”

Defending the impact of variations on a project, Sameer Daoud, Chief Development Officer and Managing Director of Drake and Scull International (KSA), argues: “Variations are not always a bad thing, when planned, progressed and addressed appropriately for the benefit of the project. Sometimes, variations could have an impact on the project with increased costs and time delays, as a result, but for legitimate reasons and, possibly, for long-term advantages.”

A BARRAGE OF ENCUMBRANCES

Variations can be an opportunity or a challenge for a contractor, but in most cases, it can be a nightmare of costs, and as Reddy says, “Variations are a joke”, because in most cases, the contractors are the ones who face the brunt of the cost of variations.

He says: “In good faith, the contractor proactively carries out the work, but there is an inordinate delay in formalising and finalising the variation amounts, as claimed by the contractor. There is no provision in the contract for the contractor to reject the engineer’s site instructions and engineering instructions, especially when they are not practical. Such practices put an enormous financial burden on the finances of the contractor, thus at times even impacting the project.”

Sharing a similar opinion on the challenges faced by the contractor, Daoud says: “Variation orders become onerous when the contractor is expected to carry on with the variations and discuss the time and cost implications at a later stage. This can certainly create confusion and lead to a negative impact on the project.”

Sometimes, the conflict is not between the consultant and the contractor; rather, it is between the main contractor and the subcontractor. As Hassan Younes, Technical

Amjad Mohammed Ibrahim

V.S Chandra Shekar Reddy

Hassan Younes

Director & Partner at Griffin Consultants, says: “The main contractor’s scope of work with the sub-contractor is not always transparent and well defined. Sometimes, there is confusion on who is designated to do what, and that could be the missing link. We often find out that variation-driven delays occur because of these discrepancies between these two entities.”

Younes says that when this critical communication is lacking between the two, the sub-contractor can deviate from the design, which may not have been part of their discussions, or may even misunderstand instructions, thus leading to a variation claim.

“If the communication is clear-cut between the two, even if a variation is needed, then the issue can be handled effectively, otherwise unnecessary delays would occur, and all stakeholders will suffer,” he says.

Despite the critical nature of the relationship between the main contractor and subcontractor, little attention is given to improve it. Voicing a similar view as Younes, Daoud says: “The subcontractor is considered as an extension of the main contractor, as they are all in the same boat.

The relationship will improve once there is clarity on the scope and commercial obligations.” Both parties, he says, must work in tandem to achieve the common goal of the construction, with planned coordination and proper disbursement of funds.

MISJUDGED EXPERTISE AND CAPACITY

Another aspect that places additional burden on contractors and consultants is the ability to self-gauge one’s own capacity and expertise, thus causing unnecessary variations. Agreeing with this, Kandasamy Anbalagan, Managing Partner of Proleed Engineering, says: “Many MEP contractors and even design consultants will bite more than they can chew by taking up huge projects, which are beyond their capacity and expertise. This practice is common among the new players in the sector. They need to self-analyse their capacity, understand the complexities of the project, evaluate their expertise and, then, bid for the project, instead of blindly jumping into the project by making tall claims.

“Domain knowledge and expertise play a fundamental role, otherwise after bagging a project, the design consultant can create a wrong design and cause the contractor to deviate from the master-concept and then come up with variations. It could also be the contractor misunderstanding the drawing and going as per his understanding, instead

18

August 2017

of clarifying with the design consultant what the drawing is about.”

However, Anbalagan adds that there appears to be a level of maturity among contractors and consultants in the GCC region. He feels they have a better understanding of the market and can discern how much load they can accept and sustain. Past economic collapses have taught them hard lessons.

When clients are offered the designbuild delivery model, they think it is an accelerated way to complete the project, without realising that it is dangerous

Agreeing with Anbalagan, Francis Alfred, CEO of Sobha Group, says that the key derailing factor that causes variations in a construction project is the non-performance of the designer and contractor, as portrayed during the initial stages. “This is purely due to the lack of judgement of their own expertise,” he adds.

THE STARTING LINE

Before a race begins, the participants practice, and there are discussions between the coach and the participants on how to strategically win the race.

Similarly, before the cycle of construction begins, there needs to be enough discussions among all the stakeholders to ensure smooth operations. Though discussions do take place, the connection often is not clear enough. Contractors,

consultants and developers need to fortify a uniform synergy to achieve the project’s goals, particularly in the initial stages. As Amjad Ibrahim Mohamed Ibrahim, Senior Engineer (Mechanical Department) at Al Qudra Real Estate says: “Developer engineers, consultants, and contractors should extensively discuss in detail the project design and specification, in accordance with the real requirements of the project and as per the standards of the authorities.

“The two critical drivers that propel variations are flaws in design and regulatory issues. It is understood that variations cannot be controlled owing to regulatory issues, especially if new amendments are passed after design and before inspection.

However, if there are flaws in the design that cause variations it adds unwarranted cost to the project.” Therefore, he suggests that designers must ritually ensure that a flawless design is developed, because that is the key component to controlling variations.

Analysing the level of involvement of contractors at the design stage, Ibrahim believes that the lesser the involvement of the contractor, the better it is for the project. He says: “If a developer uses the design-build model and goes with one contractor, the developer stands to lose out in millions, because he is restricted to only one contractor. But with the involvement of more than one contractor, the floor is open for better thought process.”

Agreeing with Ibrahim’s views, Younes says: “When the table of discussion is open to more than one contractor, you get a valued opinion from another eye. The feedback becomes more valuable, and you begin to get a different perspective, even if the contractor does not come on board.”

Even from a contractor’s standpoint, Daoud, too, believes that the role of the contractor at the design stage must be limited. However, he says, “The designer should be in close liaison with the contractor in developing the design documents, because what gets designed is not always possible to construct.

“The construction methodologies are consistently evolving and are not always reflected in the design. Objective coordination is required to avoid clashes where the consultant understands the construction methodologies and the sequence of the construction process to make better design documents that help to minimise the variations needed.”

Anbalagan, too, cautions against the practice of choosing the design-build model over conventional delivery models. He

August 2017

OVER STORY

says: “When clients are offered the designbuild delivery model, they think it is an accelerated way to complete the project, without realising that it is dangerous, because a bad contractor can take advantage and focus only on maximising his profits in every possible way, even at times putting the project at risk, with a compromise of quality.”

In this region, however, Anbalagan adds that the conventional design-bid-build is a preferred delivery model, as variations can be effectively controlled and managed.

PROTECTING THE INTERESTS

Keeping in mind the challenges faced by all, there are some legal mechanisms that have been established to protect the interests of all stakeholders. FIDIC (The International Federation of Consulting Engineers) is one such mechanism. As Dr Babus'Haq puts it, “This is a uniform code of protection for everyone, especially contractors.”

Explaining how contractors are protected under FIDIC, he says, “The preventive principle is the common law principle that protects contractors from delays caused by developers and consultants, who sometimes may change the design during implementation, causing variations to occur, thus increasing the time of the work.

FIDIC does protect all the stakeholders from variation penalties, but up to a certain extent.” Dr Babus'Haq says that sometimes, a variation may trigger a crucial delay in the completion of the project; therefore, in such cases, the contractor is entitled to a grace period, if he alerts the developer or employer in advance.

However, despite the mechanisms that are in place, some contractors, like Reddy, deal with the issue of claiming variations with a pessimistic attitude. He says: “The limit to the claim is up to 20%. However, the general attitude is ‘take it or leave it’. Therefore, a more accommodating attitude must be developed to understand the struggle of the contractors.”

BEST PRACTICES

Although inevitable, variations can be controlled through a set of ethical and strong practices. Industry voices unanimously agree that there is a huge scope to improve the control of variations, by going even beyond FIDIC and implementing a set of good industrial practices and standards.

Ibrahim says that beginning from the drawing board, a strong design, along with a strong engineering team, who are committed and can objectively make decisions is one of

20

August 2017

To evolve better, the sector has to unshackle itself from rigid methods and adopt holistic engineering approaches

the ways variations can be controlled. The drawing, he adds, must be easily understood, and the engineers must maintain vigilance to prevent unwanted variations.

Voicing a similar view, Anbalagan believes that the designer should have the full freedom without worrying about contractors.

But a good consultant should not allow a half design to reach the contractor; it must be an absolute blueprint plan. He says that a few bad apples do give the industry a bad name by not sharing all the documents; and yet, the industry is evolving in the right direction.

Agreeing on the need for a strong design element, Younes says, “Variations can be controlled to the minimum if the design is accurate, unless the client changes the direction, or we have an independent commissioning authority making recommendations.” He also points out to the crucial aspect of transparency and early

interactions between the contractor and consultants, leading to a better control and understanding of the project.

Daoud believes that another good practice is to reinforce the consultantcontractor relationship. “Accountability, improved documentation, and a well-defined initial scope and understanding of the roles and liabilities of all parties will ensure that a healthy relationship is fostered,” he says, “and not least of all, ensuring that the necessary funds are available. There should not be any nasty surprises.” He further emphasises the need for intense engagement between the consultant and contractor from the initial stages. “It is better to make it clear from day one or to take the initiative to start a discussion when you can foresee variations coming,” he says. “That is how we pave the way for smooth resolutions. When you coordinate between the various parties, you are continuously mitigating the risks

for delays and cost overruns by clearing out ambiguities.”

SUMMING UP

It is not rocket science: Variations can be controlled with efficient communication channels, transparency, integrity, and strong commitment and harmonious relationships between all stakeholders. To evolve better, the sector has to unshackle itself from rigid methods and adopt “holistic and honest engineering approaches”, as Ibrahim suggests, which will control variations. If not, as Reddy puts it, “Variations will remain a joke."

Off-line cleaning methods require periodic shutdown of the process for heat exchanger cleaning via hydro blasting, scrapers, nylon or metallic brushes or chemical cleaning.

Automatic tube-cleaning systems can be the answer…

22

C

hillers are the largest consumers of power at commercial, residential and industrial facilities, worldwide. Be it a hotel, mall, hospital, university, school, airport, office building or a factory, you name it… if it has a chiller, nine times out of 10, it is the largest consumer of power.

With a water-cooled condenser, such as a centrifugal chiller, and with the harsh and dusty conditions we face in the GCC region, reducing the fouling and the scaling, increasing the heat-transfer efficiency and reducing the kW/tonne consumption should be the primary consideration.

In HVAC applications, fouling of the chiller condenser tubes has a substantial impact on the power consumption of the centrifugal compressor. Even with good water treatment programmes, it’s common to find chillers that appear to be in good working order operating at a fouling factor of 0.0025 hr-ft2-F/Btu, or higher – causing the compressor power consumption to increase by 25% or more.

Fouling occurs, because cooling water contains minerals, such as calcium and magnesium that precipitate to form deposits on heat-transfer surfaces. Cooling water systems are also commonly plagued by biological growth that form slime (bio-film) or algae on heat-transfer areas. Additional foulants include mud, silt, sand, corrosion products and petroleum products. These foulants reduce the heat-transfer efficiency of even the best-designed heat exchangers; induce localised corrosion, leading to early equipment failure; and force shut-downs of the chiller.

Several methodologies are commonly used to mitigate or reduce fouling in chilled water plants. Typically, these include off-line mechanical or chemical cleaning or on-line mechanical cleaning systems.

Off-line cleaning methods require periodic shutdown of the process for heat exchanger cleaning via hydro blasting, scrapers, nylon or metallic brushes or chemical cleaning.

Automatic tube-cleaning systems can be the answer, leading to significant savings for chilled water plants.

Automatic tube-cleaning systems can solve condenser fouling and scaling problems that can cost you thousands upon thousands of dollars in unnecessary energy costs. The fact is that annual – which is most often the case – or periodic manual cleaning of a chiller’s condenser requires the chiller be shut

down and taken out of beneficial service.

However, after the exchanger is cleaned and returned to beneficial service, the fouling and scaling starts to develop almost immediately, lowering the efficiency of the condensers and chillers and increasing the chiller’s kW/tonne consumption until the next condenser cleaning, again, generally, 12 months later.

I will now discuss two types of automatic tube-cleaning systems…

The flow diverter or four-way diverting valve is housed within the condenser piping to and from the heat exchanger.

It is “custom” designed for various piping configurations. The valve allows for periodic flow reversal through the heat exchanger at preset times, without reducing or stopping the flow through the condenser and without taking the chiller out of service or interrupting its operation.

The valve’s operation is initiated by the programmable control panel, based on the cleaning frequency it is set up for. Once it is initiated, the valve changes the flow direction through the condenser, shuttling the brushes out of their basket position into the tube, until they are captured by the basket at the opposite end of the tube. The valve keeps the flow in the reverse direction for a few

BRUSH SHUTTLE CLEANING SYSTEM

There are many types of these Brush Shuttle Cleaning systems available in the market by different manufactures. The following is a generic explanation of the system, as they all basically operate and perform the same.

Each condenser tube is equipped with a brush and two catch baskets. The baskets are attached to each tube end by means of special epoxy. The baskets are designed to allow for easy removal and replacement of the brushes, when they wear out. The baskets are designed to hold the brush outside the tube and away from the condenser water path to avoid flow restriction and prevent measurable additional pressure drop across the heat exchanger.

Repeating the on-line cleaning cycle many times each day will prevent debris, sand sediment and scale to build up in the inner surface of the tube

minutes, until it is returned to its normal operating position, returning the flow inside the tubes to their original normal flow direction. Once the normal flow cycle is established, the brushes return to their start position, while brushing the tube again. The brush has a small interference fit within the tube, gently brushing away any foulant and scale that is built inside the tube between each cycle of operation. The cycle of operation is repeated as many times as necessary, based on the conditions and the severity of fouling and scaling. Repeating the on-line cleaning cycle many times each day will prevent debris, sand sediment and scale to build up in the inner surface of the tube, and will keep the condenser efficiency at its design condition, increasing the condenser’s real world performance.

BALL AUTO CLEANING SYSTEM

▶ Brush type cleaning system

August 2017

Sponge ball-type automatic tube-cleaning systems were originally conceived by German engineers in the 1950s for application in the power generation industry. Since they are effective at maintaining the heat-transfer efficiency of large-scale condensers, and applicable to once-through cooling systems that may have limited or no chemical treatment, they have been widely adopted in the power generation industry around the world.

Globally, more than 15,000 sponge ball-type tube-cleaning units have been placed in service in the power generation sector alone, with 50% of total generating capacity in Europe and 40% of generating capacity in Japan. For liquid chillers, the operation of sponge ball-type automatic tubecleaning systems is based on the passage of elastomeric balls through the condenser tubes. The balls are slightly larger than the tube diameter and prevent the deposition of scale and fouling materials. The sponge balls are periodically injected into the cooling water inlet line and are circulated through the condenser tubes by the cooling water flow. The balls are designed and injected in a method that enables a uniform distribution of balls across the tube sheet.

Since the diameter of a ball is slightly larger than the inner diameter of the tube, accumulation of deposits in the condenser tube is prevented by shear forces between the ball and tube wall and the wiping action of the cleaning balls. The balls are constructed of material that is much softer

than the tubes, preventing tube erosion.

The balls are collected at the outlet of the condenser in a ball trap, which includes a strainer or screen that allows water flow to continue but prevents the balls from escaping downstream. These ball trap designs utilise perforated screens of unique geometry that require no moving parts and can ensure that no balls escape to downstream processes.

After the balls are accumulated in the ball trap, they are returned to a ball collector through the operation of a recirculation pump, which supplies the necessary pressure differential for conveying the balls. The collector serves as a holding vessel between ball injections and also as a method for replacing balls in the system. The entire injection and collection process is fully automated and controlled by means of a single programmable logic controller. The controller also provides monitoring and alarm functions to ensure the system is continuously operating optimally.

Again, the sponge ball-type tubecleaning system technology has been a widely adopted best practice for optimising condenser performance in the power generation industry for decades. Advances in tube-cleaning system technology have resulted in more effective and reliable systems with enhanced scalability for the liquid chiller industry.

he five-star hotel and resort, Viceroy Palm Jumeirah Dubai is operational now and stands as a representative of a structure that features Displacement Ventilation.

Developed by SKAI/Zaya and with P&T Architects & Engineers as its Lead Consultant and MEP Consultant, the hotel, a G+17 structure, features 477 guest rooms, 211 high-end residences, six villas and four townhouses. Located in Palm Jumeirah, Dubai, and with a total built-up area of 187,347 m2, it is the fruition of a brief from the client to deliver a sustainable and energy-efficient luxury hotel.

The project has been designed as per Dubai Municipality’s Green Building Regulations and Specifications, EHS/Trakhees standards and LEED New Construction 2009.

As the project is on Palm Jumeirah, it does not qualify for LEED certification.

Apart from the usual heat-recovery devices, demand control ventilation for larger spaces, dual-flush WC with low-flow mechanisms, regulated flow mixer taps, energy-efficient lighting (LED, CFLs), daylight and occupancy sensors, the project features other sustainable design essentials, such as solar collectors catering to the hot water requirements of the hotel, and a grey water treatment plant that is providing

treated water for irrigation and for flushing toilets. All these systems have resulted in a facility that will be using up to 30% less energy, annually, when compared to similar builds – that is, luxury five-star hotels and resorts.

These systems are discussed in more detail, as follows…

DISPLACEMENT VENTILATION

Displacement Ventilation is not a new concept, but it’s something that is not very often employed in the Middle East, owing to the complexity involved in the design.

Displacement Ventilation is an airdistribution system that takes advantage of the natural air buoyancy, in which cool air is introduced into the occupied space preferably at low velocity and often also at a low level and extracted above the occupied zone. Typically, supply air temperature is higher than compared to the overhead mixing systems.

In the case of the Viceroy, the system was a result of inherent challenges that a 15m (L) x15m (W) x15m (H) Glass Cube of 3,325 m3 volume, located within the 13-storey tall gateway entrance would bring with it (Figure 1).

Among the challenges were the fact that there was no provision to locate the supply/return air ducts and associated grilles discreetly without obstructing the view through the glass panes. Also, as there was a sculpture to be installed inside the cube, the intent was that the visitors and guests should be able to see the sculpture from the outside. The situation was further complicated by a requirement that the cooling load was not to exceed by a great deal when compared to a typical hotel construction.

Considering these limitations, we recognised that Displacement Ventilation would be a viable option. Indeed, placing floor grilles to supply air at the periphery closer to the glazing (see Figure 2) would solve one of the main requirements.

Several CFD (Computational Fluid Dynamics) models were produced to study the behaviour of the supply air, note the temperatures in the Cube at different levels and to ascertain the best possible location to place the floor grilles (Figures 2 and 2a).

CFD analysis also allowed us to visually understand thermal stratification (Figure 3) and to position the return air inlets, which were then located at high levels within the frames of the entrances to the two receptions, either side of the Cube (Figure 4).

By locating the return a little over the occupancy level, we were successful in avoiding the need for cooling the entire volume of the Cube, and this resulted in a reduction in the cooling load by at least 55%. The air ducts are located in the floor void, and the AHU plant room is in the first basement.

Figure 5, above, shows a clear view of the sculpture from the pool side without any services in sight, and so, we were able to meet all the requirements successfully.

RENEWABLE ENERGY: SOLAR THERMAL COLLECTORS

The hotel features 304 solar thermal collectors, which produce hot water for the hotel, which results in an estimated energy savings of 2,600 kWh/day.

To generate hot water, flat plate solar collectors have been installed on the roof of the hotel (Figures 6 and 7). This probably is the most natural way of making use of solar energy. This technology is based on using solar thermal energy directly for heating water.

Fifty per cent of hot water generation is through the solar water heating system and the remaining through a gas-fired boiler. The 50% limitation was dictated by the available space on the roof.

GREY WATER TREATMENT PLANT

Sources of grey water for the facility include sinks, showers, baths and washing machines.

Grey water is being collected using a separate plumbing system. The installed system allows waste water to be cleaned and treated. Following the filtration process, water is used for flushing toilets and for irrigation.

The grey water treatment plant is designed to collect and treat 360m3 of grey water per day and provide 322m3 of treated water, which is around 40% of the total daily demand (at 100% occupancy).

CONDENSATE RECOVERY SYSTEM Condensate water from AHUs/FCUs is piped separately and collected in the storage tank. This water is also used for irrigation after filtration. It is believed this will further reduce potable water demand with low (almost zero) running costs.

COMMENTARY

Considering all the measures that have been adopted to conserve water and energy for the Viceroy, it would be safe to say that an energy-hungry

development, such as a luxury hotel and resort, can also be designed and constructed using available design solutions and technologies in a way that it is classified as a sustainable and energy-efficient building.

Grilles & diffusers

THE AIR MOVERS & SHAKERS Without grilles and diffusers, the purpose of any HVAC equipment is defeated. Industry insiders share their insight on the nitty-gritty of the two gizmos and on prevailing market conditions.

Benwen Lopez reports‌

August 2017

A

tired executive on a business trip checks into a luxurious hotel expecting to have a comfortable sleep but, shockingly, finds the room ambience muggy. This incident occurs very often across the world, but it has puzzled hoteliers, although the answer screams at a person when entering the room. Studies show that the problem lies in the miscalculation of airflow design in the room.

If one looks at a broader picture of an HVAC system, airflow designs rely heavily on important peripherals, such as grilles and diffusers. These apertures play a key role in enhancing the ventilation system while ensuring the comfort level of the occupants. Industry insiders point out that if accurate selection of these two components is not done, then even a sophisticated HVAC system will be fruitless.

TOWARDS GREATER IAQ

Indeed, grilles and diffusers affect the indoor air quality (IAQ) of the room, because they control the distribution of air in the room. As Eoin Crowley, Business Development Manager at TROX Middle East, says: “From an IAQ perspective, grilles and diffusers have a very important role to play. The job of the air outlet is to ensure the effective distribution of ventilated air.

Their importance should not be overlooked, as the vast majority of complaints attributed to IAQ can actually be as a result of inadequate air distribution.”

Given their importance, it is essential to consider various aspects related to them. Aspects like the materials used while manufacturing grilles and diffusers are much deserving of attention, owing to their possible contribution to the contamination of air. Concurring with this, Ahmed Alghas, Managing Director of Tecnalco, says: “As manufacturers, we ensure that the materials and the coating used for the grilles do not contaminate the air that is discharged in the room. This is critical from a safety and air pollution perspective.”

Voicing a similar view, Krikor Ohanian, Division Head of Flowtech of Faisal Jassim Group, says: “Various regulations and standards, like Estidama or Dubai Green Building Regulation and Specifications, are followed while manufacturing the grilles

and diffusers. For example, ensuring that the volatile organic compound (VOC) level of powder coating in a grille or diffuser is within the approved limit.”

Another contributing factor towards good IAQ is the acoustics in the room, and the role of diffusers in this cannot be overstated. Now, to ensure that they contribute to ensuring good acoustics, diffusers need an ally. Shpak Kostya, Marketing Manager at Aldes Middle East, explains that the baseline for preventing noisy diffusers is ensuring a balanced distribution of air. “A typical issue faced is a noisy diffuser,” he says. “If you supply too much air, it creates more noise. And even with the right selection, you can get noisy diffusers, because of poor air balancing, which results in some rooms becoming overventilated and some rooms receiving poor ventilation. As a result, you will not have desired IAQ in those rooms.”

Kostya adds that it is equally important to choose the right location for the supply and exhaust diffusers, otherwise “one can lose up to 30% of cooling duty by passing of cold air directly from the supply to the exhaust”.

Mirroring the opinion on the acoustics aspect of diffusers, Taher Saeed, Managing Director of Reetaj, says: “As the industry spirals upwards, there is a higher focus on manufacturing soundless diffusers.”

it's important for manufacturers to continue to develop and design new and aesthetically pleasing air outlets.”

Speaking of available solutions, Crowley adds: “A perfect example of this would be our new TID invincible diffuser. A finely perforated tile conceals all the technical parts, such as the swirl element, which ensures uniform air distribution. Since the technical parts are invisible, the ceiling looks smooth and as if made from one piece.”

Offering another example, Jawhari says, “Our louvred, perforated and similar-face diffusers are suitable for projects, where the control of air flow is required in a generally small area, like a classroom, a hotel room or an office.”

Cautioning on overlooking the aesthetical aspect of the room, Sriram C.M.P, Director of Betec Cad, says, “In terms of room aesthetics, ideally grilles and diffusers must be placed on flat surfaces, as irregular surfaces can restrict the ‘Coanda Effect’ and result in cold air dumping.”

Offering a different view, Ohanian believes that while aesthetics are crucial, it is also important to focus on the performance of the diffusers. He says: “Aesthetics are very important while selecting a grille, especially to match the interiors or theme of the area in which it is installed. But performance should be given more priority, because without comfort the aesthetics cannot be thoroughly enjoyed.”

DYNAMICS OF ROOM AESTHETICS

Jamal Jawhari

August 2017

When it comes to grilles, an essential consideration in their selection is the design aesthetics of the room or the building.

Elaborating on the importance of the design aesthetics, Jamal Jawhari, CEO of Safid, says: “Both shape and colour of the grilles are very important and need to be verified for different aesthetics. Air outlets are mostly looked at as an architectural product, despite their technical properties.

And grilles are the most visible product amongst the HVAC product chain.

In view of this, Jawhari says, “We have developed many shapes of air devices, not only to meet air-distribution requirements but also to fit in with the overall design look of a room or building, something which architects advise us, and it helps to integrate the devices into their design.”

Voicing a similar view, Crowley says: “Aesthetics have now become an overriding factor when selecting air outlets. Designers typically have to work within the architect’s scope, even if this has a negative impact on air distribution within the space. Therefore,

Energy efficiency needs to be carefully considered when selecting air outlets.

It is an unseen aesthetic of our design

DRIVING UP ENERGY EFFICIENCY

Krikor Ohanian

Shpak Kostya

Taher Saeed

Although non-mechanical in nature, grilles and diffusers do play an important role in driving up energy efficiency. For Sriram, it is the cycle of design and quality manufacturing that drives up energy efficiency. He says: “It is important to come up with an effective design in order to make sure there is a low pressure drop, which leads to high system efficiency.

“Apart from design, manufacturing of components are a very important factor, in order to ensure efficiency of the product. If inferior quality materials are used during the manufacturing process, the energy efficiency is affected, and the life span of the product is decreased, too.”

For other manufacturers, as well, energy efficiency is an embedded aspect of their manufacturing philosophy. As Crowley says: “As with everything we do now, energy efficiency needs to be carefully considered when selecting air outlets. It is an unseen aesthetic of our design.

“Our swirl diffuser, which has specially designed, three-dimensionally profiled contour blades, allows for high air volumes, achieving both low pressure drop and reduced noise levels. Therefore, by keeping pressure to a minimum, we can reduce energy consumption.”

CONSIDERING ADPI

Brian Suggitt

40

August 2017

The Air Diffuser Performance Index (ADPI), as defined by ASHRAE, is a critical rating for air diffusers, because it aids the selection process of the right diffuser. Studies show that a higher ADPI – above 80 – is always better, but it depends on the type of environment.

Concurring with this, Jawhari says: “It depends upon room load and the type of air devices required. Our thumb rule is based on ASHRAE’s fundamentals: For 20 Btu/hr-ft2, T50/L for maximum ADPI (between 85 and 90) is 1.0-1.5, in case of high-side-wall grilles, straight-vane grilles and ceiling diffusers, and 0.3-0.7 in case of linear-slot diffusers, and T50/L can be at 1.5-2.0 for perforated ceiling and similar diffusers.”

Agreeing with Jawhari, Ohanian says that the higher the ADPI, the greater is the comfort level within the space. Generally, an ADPI of 80 and above is recommended for this region, he adds.

However, Kostya believes that the ADPI index is not very popular in the GCC region, and the main criterion to select diffusers is noise and terminal velocity in the occupied zone.

Consultants usually provide a perfect specification, but the problem crops up when the contractors change the specification and use a low-quality product

TESTING AND QUALITY

Testing and quality are two fundamental business tenets, without which the entire business could collapse for manufacturers of grilles and diffusers. Different manufacturers have adopted different practices, yet most of them conform to general international standards, such as the ISO 9001:2015, OHSAS 18001: 2007, Intertek USA, AHRI, AMCA, UL certification, in addition to Dubai Civil Defence and other independent testing facilities in the region.

THE JOURNEY OF CHALLENGES

As the GCC region is experiencing a tense economic climate, the challenges are mounting, yet the industry players have a sanguine attitude that the oasis is coming closer. As Sriram puts it: “Global oil prices have fallen sharply over the past few months, leading to significant revenue shortfalls in many energy-exporting nations. The impact seems to be temporary, but it would take some time to bounce back to its previous state.”

Citing the Saudi Vision 2030 as a beacon of hope, Jawhari says: “We are very optimistic with the Vision 2030, and we are confident that the Saudi market will witness a lot of improvements in the coming years due to the strategic economical plans set by the government. Hence this roadmap will provide new opportunities and key projects in the Kingdom.

Brian Suggitt, Managing Director (Middle East) of Systemair Trading, adds: “The challenges now are no greater or smaller than they have ever been. Technology has enabled us to be more aware of, and sensitive to, market conditions and, hopefully, deal with the volatility prevailing. We have to assess and acknowledge market conditions and continually plan to deal with them.”

Also identifying the volatile oil prices as the main culprit for the market tremors, Crowley says: “Fluctuating oil prices and disturbances in the region do have a negative impact on the market. Nevertheless, with the Expo 2020 coming up, our market predictions remain strong.” He further adds that his company is currently maintaining a strong market position, with projects lined up for 2018.

However, Ohanian points out to the aftereffects of the challenging market conditions.

He says: “The main challenge in the current market circumstances is the price and the unfair competition. The trend in finalising

the orders is more price-oriented rather than other important factors, such as quality, standards, certifications and service level.”

Another market challenge is the on-going tug-o-war among the consultants, contractors and clients over what type of grilles and diffusers need to be installed. Explaining this on-going issue from a trader’s perspective, Saeed says: “Consultants usually provide a perfect specification, but the problem crops up when the contractors change the specification and use a low-quality product.

It affects the entire system when cheap products are used.”

Elaborating on the challenges faced by traders, Saeed adds: “When an order with a particular specification is placed, the manufactured product is not always 100% accurately matching the given specifications, because some manufacturers are looking to cut down cost.”

Sharing a similar opinion, Suggitt adds:

“In the general day-to-day market for these products, local manufacture throughout the region has driven the market pricing down. There are some very good local manufacturers and others not so good.”

THE WRAP

Despite the rollercoaster ride the market is going through, with the fluctuation in oil prices, manufacturers of the twin peripherals expect to witness substantial growth. As Alghas says: “Every industry will be affected in one way or another by the oil prices, but what matters is if you are known for your quality and service, you will manage even through tough economical climates.”

Bahrain offers clarity on GCC Low Voltage Regulation for ACs Says enforcement of the regulation at the moment is limited to window and split air conditioners

By CCME Content Team

Markus Lattner

he Bahrain Standards and Metrology Directorate has announced that the enforcement of the GCC Low Voltage Regulation for Air Conditioners is limited to window and split air conditioners with HS code 8415 10, Eurovent Middle East said in a statement issued in the end of June.

Lack of clarity and different interpretations of the regulation in GSO member states have resulted in blocked shipments, as manufacturers tried to comply, Eurovent Middle East added. In that context, the announcement from Bahrain is a welcome development.

Eurovent Middle East has been discussing with GSO, ESMA, the Bahrain Ministry of Industry and the EU Trade Delegations regarding the regulation and its implementation in several countries. “We are happy to see that our activities contributed to this rather quick reaction on behalf of the Bahrain government, which will bring more clarity for our manufacturers.” said Markus Lattner, Director of Eurovent Middle East.

The Directorate will enforce the GCC Low Voltage Regulation for other Air Conditioners, including ducted-split, rooftop package and multi-split systems at a later stage, the announcement further said.

Lattner said Eurovent Middle East will follow up and inform its members on any new developments. He also underlined the advantage of a joint industry approach. “Rather than calling in individually and upsetting people,” Lattner said, “we could put forward an official statement and ask for our position to be taken into consideration.”

Misrepresentation of UL certification What’s causing all the confusion?

By Hannah Jo Uy | Features Writer anufacturers in the GCC region showing a commitment to acquire UL certification for their products often bemoan the rampant practice of misrepresentation of certification by some manufacturers, and how it is affecting them. Speaking to Climate Control Middle East on the issue, Jonathan Gonzalez, Project Engineer for Building and Life Safety Technologies, Laboratories (UL) Middle East, said the confusion was the result of a unique and particular twist on the language.

“UL certifies, but it also develops test standards,” he said. “So, anyone can test [according to] UL standards and say, ‘I can do UL’ – that’s where the confusion lies. Other people can test to meet UL requirements. Even our competition, they can test [according to] UL, but what they cannot do is provide a UL label.”

Gonzalez emphasised that UL makes the products undergo the same type of tests, but it doesn’t necessarily mean they have the official UL certification, and that they have been vetted by the organisation. “We have laboratories across the world that test to UL standards,” he said. “Every lab can test to a UL standard. Nowhere will they say that only UL can test for UL. Here, locally, there is a lab that can test to UL standards.”

It is for this reason, Gonzalez said, that UL, as a third-party certification company, places strong emphasis on the certification scheme, which includes the testing and certification standard development. He added that UL can also test according to different standards but that, at the end of the day, only the organisation is able to give the authentic UL certification. Gonzalez conceded that UL certification does not come cheap, adding that the high cost is owing to the great value UL places in what it does. An important part of the certification scheme, he said, is not just the testing, but the rigorous follow-ups on the samples to ensure their consistency.

Empower signs Global Cooperation Agreement at IDEA’s Annual District Energy Conference The Agreement brings together countries such as Canada, China, Colombia, Denmark, Germany (European Union), Japan, Singapore, United Arab Emirates, United Kingdom and the United States

By CCME Content Team

n an effort to enhance the conservational impact and development of District Cooling in the UAE, utility provider, Empower, which is a member of the Board of Directors of International District Energy Association (IDEA), and a partner of the United Nations Environment Ahmad Bin Shafar Programme’s (UNEP’s) Global District Energy in Cities initiative, signed a Global Cooperation Agreement at the 108th IDEA Annual Conference & Tradeshow, held from June 26 to 29 in Scottsdale, Arizona, in the United States.

Earlier this year Ahmad Bin Shafar, CEO of EMPOWER, was chosen

by United Nations to become the special advisor on District Cooling within its “Global District Energy in Cities” initiative.

The Agreement defines common objectives and a collaborative framework intended to increase deployment of District Energy in countries around the globe to increase energy efficiency, reduce emissions, strengthen local and regional economies, and deliver the social and environmental benefits of efficient District Energy systems.

Speaking on the occasion, Bin Shafar said: “At Empower we’ve always been committed to accelerate deployment of District Energy.

The signing of the Global Cooperation Agreement is a testament to support Dubai’s Integrated Energy Strategy, directed by His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai, to build a green economy in the UAE and transform Dubai into a global centre for clean energy and green economy.

By Benwen Lopez | Assistant Editor

By Hannah Jo Uy | Features Writer n a deal signed with Enova, four malls belonging to Majid Al Futtaim, will be powered through solar panels by 2018, the company said through a Press communiqué. The malls include the Mall of the Emirates, Mirdif City Centre and Deira City Centre. The deal adds to the existing three malls being solar powered by Enova.

Speaking on the development, Anne Le Guennec, CEO of Enova, said: “With our energy management solutions, we help firms achieve their best performance and environmental targets, based on a comprehensive package of services, including design, commissioning, strategy and long-term maintenance.”

Sharing the details of the project, she said: “Under this deal, about 12,500 panels will be installed across the buildings, covering an area of 25,000 square metres, including 1,020 carports.”

Le Guennec added that the solar panels would also be powering up the HVAC systems of the malls.

Explaining the dynamics of the solar-powered HVAC systems, Amin El Najjar, Director – Operations at Enova, said: “The solar PV plant generates electrical power in compliance with the utility grid and according to the following specifications: Three phase AC 230 to 400V 50Hz, which is exactly the same as what DEWA supplies to any consumer. This is how we will be powering all the HVAC systems and other electrical equipment, with the exception of medium-voltage centrifugal chillers.

“The power to be supplied from the PV plants to all HVAC equipment is an open system, interconnected with the DEWA grid.”

Le Guennec said that she expects a reduction in carbon dioxide emissions by 3,200 tonnes per year.

in data centres are designed not to set the return temperature but only cool the hot air entering it. It does not cool mixed temperature air.”

Explaining the dynamics of air mixing, Sainani said: “You have cold air being consumed from the front of the rack, and hot air being exhausted from the back of the rack, but when there is no proper segregation done to prevent air mixing, a mixed temperature air develops and leads to creation of hot spots.

“As in most cases, data centre operators do not understand the physics of cooling, and accelerate the problem even further

by lowering down the temperatures of the chilling systems, leading to freezing temperatures, and this results in some racks getting very cold, while some remain hot.

Therefore, it is critical to prevent air mixing from occurring, in order to reduce the load on chillers and improve energy efficiency.”

Suggesting a solution for improving energy efficiency, Ajay Rathi, Head of Information Technology at Meraas Holding, added: “The problem is that energy efficiency is not built in traditional data centres. Thus, the answer is modular data centres.” They are highly energy efficient and even cost effective, he said, adding that modular

solutions constitute an emerging trend and present themselves as alternatives to brick and mortar data centres.

Elaborating on the energy efficiency boosters, Sainani added: “Better behaviour towards energy efficiency can be driven through regulation, such as a carbon tax.

We can take an example from a country like Singapore, which has come up with an energy star rating and a Green Mark Award for data centre efficiency.”

Rathi added that standards, such as power usage effectiveness (PUE), would encourage data centre operators and managers to drive towards energy efficiency.

Is steam cleaning healthy for HVAC systems?

Industry representatives have mixed opinions

By Benwen Lopez | Assistant Editor

lthough steam cleaning is one of the trends when it comes to cleaning HVAC systems, the question is whether it is effective enough or not? Industry representatives have a mixed opinion on the subject.

Highlighting the benefits of steam cleaning of HVAC systems, Meraj Asad Khan, Sales & Product Head of Retail Sales Channels (UAE) at Karcher, said: “Steam is pure, and it condenses into simple water and not only cleans but sanitises the HVAC equipment, as well. The main benefit is that it is healthier than using chemicals, which have harmful effects. It is also known to have a low impact on the environment.”

Differing from Khan’s view, Leo Radford,

A

Managing Director of Envida Technical Services, said: “If using steam cleaning process, it depends on which components of the system need cleaning. Components like coils and filter racks can be steam cleaned, and it is more economical than environmental friendly.

“Steam should never be used for cleaning of ducts; rather, dry cleaning methods need to be adapted, as prescribed by the National Air Duct Cleaners Association (NADCA) standards, because steam cleaning can invite moisture and mould problems.”

Radford further added that it is important to have periodical cleaning of equipment rather than once every few years.

he design-build model is expected to dominate in the GCC region in the coming years, over the traditional design-bid-build or design-tender model.

Christopher Seymour, Regional Development Director of Mott MacDonald, expressed his firm opinion in this regard: “Design and Build, or adaptations of it, will become the procurement route of choice over the next few years.” Seymour emphasised that in light of this, the supply chain, in general, will need to become more proficient in understanding the roles of the various parties to enable more accurate pricing and apportionment of risk.

“Technology is at the ‘front of mind’ of most people in the industry,” he said, “but the industry is still some way from the level of adoption of BIM, in particular, being universal.” Seymour emphasised that currently, there is a lack of sufficient and widespread use of common data environment for project documentation. He noted that this is a vital aspect to ensure that the supply chain is able to address the needs of clients at greater speed, with better quality and in a more cost-effective manner, as demanded by the market today.

Carrier notes increased demand for higher efficiency products in the Middle East Demand driven by efforts underway by multiple stakeholders to reduce the financial burden arising out of increasing power tariffs in the region, says company

By Hannah Jo Uy | Features Writer

he Middle East region is expressing a greater demand for higher efficiency products. This was revealed by Giorgio Elia, Vice President and Managing Director, UTC Climate, Controls & Security Middle East, who added that the leadership in the region is steadily enhancing efficiency standards. Overall, he said, the demand was owing to enhancements in technology and a determination to help reduce the financial burden arising out of an increase in power tariffs in the region.

Elia said the shift has led to an increased demand for higher efficiency air conditioning solutions from regulators as well as end users and contractors.

“The trend is prevalent across the region,”

Giorgio Elia

he said, “and has had an impact on every product category within HVAC.” Highlighting key trends in the region, Elia noted the trend is towards evaluating chillers on an IPLV (Integrated Part Load Value) basis, which is leading to a shift towards variable-speed technology in centrifugal chillers. He commented: “Upcoming projects in the GCC region focusing on higher IPLV plants will help in delivering lower building annual energy consumptions to the users.”

Elia said this has also made District Cooling plants increasingly popular in the Middle East, “taking advantage of their higher efficiency and diversity”. He added that currently, most plant operators also want heat recovery in the airside, and it is important to them that the equipment is Eurovent-certified, demonstrating equipment performance (for example L1/ D1/T2/TB2 classification for Air Handling Units) through third-party certification.

Elia said that the US Green Building Council’s LEED standards and regulations are also driving better IEQ and energyefficiency across the Middle East, as LEED standards grow in popularity.

By Hannah Jo Uy | Features Writer

nderwriters Laboratories (UL) is on a global expansion mode. Jonathan Gonzalez, Project Engineer for Building and Life Safety Technologies, UL Middle East, while speaking on the global expansion of the company, said it is moving to strengthen its position in the Middle East, including the UAE, which is home to diverse certification standards.

U

n recognition of the potential of the Middle East data centre market, Munters is collaborating with Built Environment (BE). Julian Iosifescu, Sales Engineer for Data Centres, Munters, described BE as “a reliable and knowledgeable Munters representative firm for the Middle East”. He added that Guy Crasnier, Georges Seguin, Aleks and Dusan Cvijic, the owners of BE, represent an excellent combination of knowledge in the Munters data centre product line and a comprehensive understanding of the Middle East market.

Iosifescu said the company’s technology is able to operate efficiently under weather conditions in the Middle East. He added that aside from operational savings, the systems will allow data centre clients in the Middle East to save on the total cost of ownership “by reducing the electrical infrastructure of the data centre and, implicitly, of the electrical grid”.

Jonathan Gonzalez

Gonzalez said that the company, founded and headquartered in the United States, continues to enjoy a strong presence in its home country, as it remains indispensable among manufacturers that want to distribute their products there. However, he also said that it has since expanded exponentially. “We are now a global company in over 38 countries, with 170 offices and inspectors around the world, he said. “So, traditionally, we did just have a monopoly in the US but now, for the past 50 years, we have been a global company and, I would say, there’s more global employees in UL than in the US.” He added that while UL has a strong presence in the GCC region, the UAE features a more diverse market and is, as a result, a bit more competitive. “In the UAE, you have options,” he said. “They have consultants, contractors and architects, from all around the world. So, they are flexible with regard to accepting UL standards, British standards, etc.”

He also said that, from his observations, the country seems to favour a European-based approach, and, thus, UL is aiming to present its case to local regulators and authorities and showcase the standards that have made it dominant in the United States. Currently, Gonzalez said, certification in the country is mandatory only in the sense that products should be tested and certified, but not necessarily to UL, owing to the availability of other standards and certification.

or regulation on energy consumption,” he explained. This, he said, means that there are many systems that are not consumer-friendly and which require a lot of electricity. As a result, the company is proposing to replace existing systems with VRF technology, promoting it as a possible solution by calculating the savings building owners will achieve through doing so.

The department, said the company, will have a dedicated team conducting comprehensive energy surveys to identify the energy profile of the assets and to propose customised techno-commercial solutions with the aim of providing savings of up to 50%

and with pay back periods down to less than three years. Taqeef also said it will provide cooling solutions as “value engineering for new constructions” and adequate energy conservation measures, in line with LEED and Estidama requirements and measurement and verification.

Ghussein added that every customer has different expectations with regard to what could be considered a ‘reasonable payback period’, following investment on upgrades, but that Taqeef is committed to studying the possibility of the system. Ghussein said the first trial of the VRF system has confirmed that there is a lot of savings possible in existing buildings. Retrofitting them, he emphasised, can be a significant factor in helping them slash energy consumption.

Taqeef noted that the company has a number of retrofit case studies and operational experience, and that it aims to increase awareness in the market and utilise technologies like VRF systems to “provide optimised efficiency, greener technology, environmental friendly refrigerant and flexibility in design”.

Erin Mezle Highlighting the features of the tool, Mezle said: “The Fujitsu Airstage VRF systems can now be controlled through the IntesisHome app, which can be accessed through either an Android or an iPhone.

Additionally, users can access the app through its website and control the systems from a computer. A cloud server manages the entire process.”

Explaining how the solution works, Mezle added, “A wired device is installed near each unit, which controls its operation and communicates over Wi-Fi to the Internet router all the data of the system to the end-user.”

Highlighting the benefits of the tool, she added: “The end-user has a better control of the various functions of the HVAC system, which include scheduling of the cooling or heating of the room or building. It also allows the user to set the desired temperatures, and it provides instant alarm notifications and error reporting in several languages.”

Bitzer offers digital support for using its Varipack frequency inverters Company says the precise coordination of its compressor and frequency inverter increases compressor efficiency in full-and part-load conditions

By CCME Content Team

itzer has published a video explaining how to design, configure and commission its Varipack frequency inverters, the company said through a Press communiqué. The video can be found on the YouTube video platform and offers valuable assistance when it comes to using the external frequency inverters.

The video shows Bitzer employees designing a Varipack frequency inverter for the requirements of a refrigeration system with Bitzer compressor. There are two versions to choose from, with the required steps explained in English or German. Users also require the Bitzer software, BEST (Bitzer Electronics Service Tool) and a BEST interface converter or an Ethernet cable. The two software tools are available free of charge on the Bitzer website, the company said. Once the Varipack has been installed and wired as recommended, it can be commissioned and configured, the company added.

According to Bitzer, in combination with its reciprocating compressor, the Varipack frequency inverters belong to its IQ product range and offer an intuitive commissioning process that doesn’t require any specific knowledge about frequency inverters. Its advantage is that it adjusts to ideally suit the system’s current cooling demand, reducing both energy consumption and running costs, the company said. The precise coordination of compressor and frequency inverter saves additional energy and thus increases compressor efficiency in full-and part-load, the company added. The external Varipack frequency inverters are also designed for modern motor concepts, including the permanent-magnet motors of the Bitzer Ecoline+ reciprocating compressors and other motors modified specifically for frequency inverters, the company further added.

ioclimatic’s air-purification system principle yielded compelling results again at the Hanover Fair, in early July, with energy- and cost-efficient air purification and sterilisation solutions stoking considerable international interest, the company said through a Press communiqué. According to the company, the system runs on the bipolar-ionisation principle, which eliminates the use of chemicals or fragrances, thus accommodating contemporary user requirements on sustainability and cost-effectiveness. The company said demand proved especially high for air conditioning and ventilation applications, such as its aerotron system for whole buildings.

“We saw an overwhelming response to our products, said Carsten Feuerhake, Sales and Marketing Manager, Bioclimatic. “There’s already a lot of interest in our technology, and this has expanded in the international arena.”

Bipolar ionisation takes advantage of the natural process of ionisation, working in a similar fashion to electrical discharges in a storm in cleaning air. According to Bioclimatic, the system is highly effective with low energy requirements. Positive and negative ionisation, the company said, also significantly reduces harmful airborne bacteria, mould spores and pollen. Air duct pressure is maintained, the company added, greatly increasing efficiency. Annual visual inspections and duct cleaning can be carried out by users, making servicing and maintenance easy and cost-effective, Bioclimatic further added.

According to the company, the aerotron range, in particular, attracted much interest at the Fair. Built to specification, the integrated systems are generously dimensioned with a range of effectiveness well-suited to large indoor spaces, the company said. An aerotron air sterilisation and purification system, the company added, integrates into existing or new ventilation ducts and air conditioning systems, but it can also be flange-mounted from outside. Restaurants, wellness centres, conferencing facilities, commercial kitchens, shopping malls and warehouses are prime sites for installing an aerotron system. “It’s not just air conditioning, Feuerhake said. “Natural ways of fighting germs have been gaining in focus.”

US Chiller Services awarded full O&M of Empire State Building Company also enters into a joint-venture agreement with The BP Group to offer full range HVAC services to New York City tri-state area

By Hannah Jo Uy | Features Writer

S Chiller Services has been awarded full O&M of the Empire State Building. Dan Mizesko, Managing Partner of Al Shirawi US Chiller Services, confirmed this and said that the scope of the agreement includes maintaining a mix of electricdriven VFD centrifugal chillers, steamturbine-driven centrifugal chillers and oil-less, magnetic-driven centrifugal chillers as well as the entire chilled water plant and ancillaries. Mizesko added that, equally as important, they are also tasked with “achieving energy (electricity, steam and water) reductions and efficiencies”.

The contract’s start date, he said, was on July 1, 2017 and features a five-year agreement.

Mizesko shared that US Chiller Services has entered into a joint-venture agreement with New York-based HVAC specialist, The BP Group, to offer the full range of HVAC services for large- tonnage chillers and equipment to an expanded client portfolio in the New York City tri-state area. “The new joint venture,” he said, “will offer an independent alternative solution to the large-tonnage market in the New York metro area, inclusive of New Jersey, Westchester

U

and Connecticut from the Original Equipment Manufacturers (OEMs) currently dominating this market area.” He emphasised that the portfolio of services and energy solutions offered

by US Chiller Services, combined with The BP Group’s strong reputation in client services, is the “key to the future success of US Chiller Services NY”.

Mizesko said that the new development is a “watershed moment” for the company in New York. “It means everything to us,” he said. “To be frank, the Empire State Building is without question, the most iconic building in the world. When we met with the Empire State Building, the key factors that they wanted to achieve were reliability and energy savings. This is our whole focus at US Chiller Services. So, after almost a year of due diligence, we were selected as the service provider for Operation and Maintenance of the Chilled Water Plant.

Our experience in Operation and Maintenance of some of the largest and most sophisticated chilled water plants in the world allowed us to differentiate ourselves from any competition.”

He said that the company is looking forward to delivering to the Empire State Building the “savings and reliability that we assured them we would provide and that a facility of this stature deserves”.

Roman maritime insulation practices and ‘sweaty’ ships Industry expert explains ancient paradox of solar load

August 2017

ncient shipbuilders did not have access to the sophisticated technologies readily available to us today, yet they apparently managed to design efficient ships that crossed continents, leading to the discovery of new worlds. For centuries, these shipbuilders’ understanding of insulation was confined to tar mixed with cork. Harley O’Neill, Owner and Director of SuperyachtME, noted that cork served as the first form of insulation and also provided sound insulation,

A

because it had a damping effect.

O’Neill provided an ancient background of seafarers, as he segued into a comprehensive discussion on the paradox of solar load within the maritime industry, highlighting key points that require greater awareness from the sector. “The industry needs a better understanding of what a ship goes through over time,” he said. It also needs to have a better grasp of how existing insulation products, mass conventional materials, go through a reduction in their ability to provide

US-based CMS issues Legionella directive Encourages facilities to utilise ASHRAE Standard 188, which establishes Legionellosis risk management requirements for building water system

By CCME Content Team

o reduce cases of Legionnaires’ disease in health care facilities, the Centers for Medicare & Medicaid Services (CMS), USA, announced that Medicare-certified healthcare facilities in the United States must develop and maintain water-management policies and procedures to reduce the risk of growth and spread of Legionella and other opportunistic pathogens in building water systems. The directive has an immediate effective date, CMS said through a Press communiqué.

Legionnaires’ disease is a serious type of pneumonia caused by bacteria, called Legionella, that live in water. Legionella can make people sick, when they inhale contaminated water from building water systems that are not adequately maintained.

The announcement was made in a recent memorandum to the State Survey

T

Agency Directors and includes hospitals, critical-access hospitals and long-term care facilities in the United States.

Most notably, CMS called for the utilisation and compliance of ASHRAE Standard 188: Legionellosis: Risk Management for Building Water Systems, which was developed to assist designers and building operators in developing a water-management plan that includes practices specific to the systems that exist in a particular building, campus or health care facility.

The timing of CMS’ decision is significant, as the Centers for Disease Control and Prevention (CDC), in the United States, released a report last month stating that more than 76% of Legionnaires’ disease cases acquired from Legionella exposure in health care facilities can be particularly harsh, including possible fatal risks to patients.

“Incorporating good design, operations and maintenance procedures that prevent the growth and spread of Legionella is vitally important in all buildings, especially health care facilities,” said Michael Patton, member of ASHRAE Committee SSPC 188.

“These are regarded as the best methods for preventing this potentially fatal disease.

ASHRAE has been at the forefront of

a predictable insulation value, he added.

O’Neill elaborated on what he considers an ‘age old problem’. He said that as the sun continues in its rotation, it impacts the ship. As the external hull side of the vessel, which was cooled throughout the night, is exposed to the rising sun, it heats up. As the hull hits saturation temperatures, the points of which vary depending on the material, it then radiates into the insulation, which was cooled all night long. “It starts latent and turns into heat flux,” he said.

establishing best practices through ASHRAE Standard 188. We are pleased that CMS is taking a strong stance on this issue.”

The CMS memo calls on State Survey Agency Directors to conduct a facility risk assessment, implement a water-management programme that considers ASHRAE Standard 188 and the toolkit developed by the CDC entitled, “Developing a Water Management Program to Reduce Legionella Growth and Spread in Buildings: A Practical Guide to Implementing Industry Standards.” The directive also requires facilities to specify testing protocols The CDC toolkit – initially released in 2016 and updated in June 2017 – is based upon ASHRAE Standard 188 and provides a checklist to help building owners and managers identify if a water-management programme is needed, examples to help identify where Legionella could grow and spread in a building and ways to reduce risk of contamination.

This produces two different temperatures, he said, and leads to condensation in between the hull and conventional materials. “It heats up the insulation material all day long,” he added, “and throughout the day your ship combats temperatures that shouldn’t be there. People say ships don’t sweat, but every ship sweats.”

O’Neill explained that as the hull pushes and contracts it crushes the internal movement of the hull, flexing the weight of that conventional material. If that moisture is absorbed in that rock wool, he said, it moves. As it moves, it begins to bounce, and as it bounces it crushes the material. He emphasised that the ultimate ‘doom for the ship’ is that as the gapping opens up, the condensation turns to “excess weight, bacteria, electrolysis – all that excessiveness shouldn’t happen”.

WEG introduces new K1W water-cooled motor Company says its 700 kW motor from its subsidiary, Antriebstechnik KATT Hessen features high efficiency and many application options

By CCME Content Team

EG, manufacturer of motor and drive technology, has recently launched the new K1W series of water-cooled motors. The newly developed K1W motors are available up to energy efficiency class IE3 with rated power up to 700 kW and compact dimensions.

They are suitable for a broad spectrum of applications, including mixers, extruders, injection-moulding machines, printing presses, paper machines and wire-drawing machines. The new series of motors was developed by WEG’s German subsidiary, Antriebstechnik KATT Hessen, commonly known as AKH. “The K1W series is a completely new line of water-cooled motors, which are cost-effective and meet the needs of a large number of applications, thanks to numerous options,” said Uwe Guthardt, Managing Director of AKH. “Among other things, they are a good choice when a lot of power is needed in a small space and the lowest possible noise level is desired.

The K1W series is ideal in situations where an external fan is not possible due to a high dust burden in the air or the motor heat cannot be dissipated directly to

and bearing shells of the standard version are made from steel.

The electrical options include optimisation for variable-speed-drive operation as well as special voltages and frequencies, WEG said.

The mechanical options of the K1W motors, WEG added, include water-cooled shafts, electrically isolated bearings, automatic lubrication, and foot or flange mounting.

ederico Muñoz Sánchez, Technical Commercial Director, CEIS, has revealed to Climate Control Middle East that the company is set to launch a laboratory for air-to-air equipment in Madrid, Spain, which, he says, will be the largest in Europe. Sánchez spoke on the history of CEIS and values that underpinned this recent move: “CEIS (Testing Innovation and Services Centre) is a 100% Spanish private testing laboratory, leading the air-to-air testing technologies in Europe. Since 1994, CEIS has tested and evaluated more than 4,000 samples to check their energy performance. With this background, Federico Muñoz CEIS decided last year to increase Sánchez its testing capacities, not just in terms of units under tests but also in terms of power of the units.”

Munters introduces air-side economisers for data centres Move follows the publication of ASHRAE TC9.9

By Hannah Jo Uy | Features Writer

unters recently introduced air-side economiser systems for the data centre market.

Julian Iosifescu, Sales Engineer for Data Centres, Munters, noted that the business opportunity presented itself following the publication of the new ASHRAE TC9.9 Thermal Guideline for Mission Critical facilities, which increased the temperature range allowed inside the data centres.

Iosifescu emphasised that the company’s success has been based on the 40-plus years of experience of Virginia, US-based Des Champs Technologies in the field of air-side economisers.

Munters acquired Des Champs in 2007. “Keith Dunnavant is Julian Iosifescu the person who started the DC field at Munters/Des Champs,” he said. “Keith has earned a tremendous amount of success due to his outstanding efforts. It has been a groundbreaking job to convince the engineers and end users to adopt the new ASHRAE Thermal guideline and include the Munters indirect Air Side Economiser (IASE) units into their projects.”

Iosifescu noted that with regard to the penetration of IASE technology into the data centre market, the company has passed the pioneering and early-adoption stages. “Right now, our products are at the beginning of the large adoption phase,” he said.

Data centre engineers, he said, have realised the notable operational and capital savings that can be had through designing data centres based on the new ASHRAE Tc 9.9 Thermal guideline. “The increase of the Supply Air Temperature from 55 degrees F to 75 degrees F (from 12 degrees C to 23.8 degrees C), and even higher, has placed the data centre projects in the sweet spot of the IASE operational parameters,” he said.

Iosifescu also said that in the last few years, Munters has observed a shift in the data centre market from CRAC (DX-based) units to different forms of economiser systems.

Since Munters is able to offer wet and dry IASE solutions, he said, the company is able to address the unique needs of their data centre clients.

M

The introduction of the regulation, which will force energy labelling in Europe for air conditioning units above 12 kW, he said, has also had a major influence on the CEIS decision. "In the coming months, CEIS will launch the largest European laboratory for air-to-air equipment, including a VRF technology testing facility, at Móstoles in Madrid, Spain,” he added.

Sánchez added that CEIS, as a test laboratory, will be carrying out the evaluation of VRF technology based on the SEER approach and that it will be able to test equipment up to 100 kW, which in the case of the VRF, means having eight cassette indoor units or 12 ducted indoor units. He added that the laboratory is backed by both strong investment and comprehensive knowledge on test methods. He said that since the number of VRF manufacturers is not so high, CEIS will be able to utilise its facilities in Spain to address the needs of leading manufacturers in Japan, Korea and the Middle East region.

TROX supplies acoustical solutions to Hamburg’s Elbphilharmonie concert venue “The aim was to prevent visitors from feeling or seeing the room air conditioning system – and under no circumstances were they supposed to hear it,” says company official

In mature markets, like the United States, retrofits probably account for 70% of installs, says company official

By Hannah Jo Uy | Features Writer

ROX has provided air quality, air comfort and acoustical comfort systems to the Elbphilharmonie concert venue in Hamburg, which opened its doors to the public, earlier in the year. Matthias Kasprowicz, Regional Managing Director of TROX, spoke with Climate Control Middle East on the project and how, among other features, TROX was able to minimise unwanted sound at the venue.

Designed by Jacques Herzog and Pierre Meuron, the venue is home to two concert halls, a smaller hall with a capacity of 550, and a Grand Hall, that can house up to 2,100 people. “The project was, indeed, a major challenge,“ said Kasprowicz, “and was handled by my colleagues in TROX Germany.

The aim was to prevent visitors from feeling or seeing the room air conditioning system – and under no circumstances were they supposed to hear it.“ Contractors chose the fire protection and ventilation technology products from TROX, he said. The company installed around 400 fire dampers and around 90 smoke dampers in the periphery of the large concert hall as well as swirl and slot diffusers, which he said, provide silent air supply. To manage the air distribution, TROX supplied irs Varycontrol controllers.

Regulations driving R&D in US, says Tecumseh

faced, Kasprowicz said that the Grand Hall was constructed on the basis of the vineyard principle. To address the peculiarities associated with this, he said a plywood model of the hall was constructed, incorporating 2,000 little dolls dressed in felt garments. “Tiny caps were used to simulate hair,” he said. “Every element was precisely recreated on a 1:10 scale – including the wall structure, flooring and reflectors.”

Based on this work, he said, 10,000 wall and ceiling panels were developed using highly compressed material made from gypsum and waste paper. “Individual reliefs, created on a computer, were milled into the surfaces of the panels and indentations incorporated into them,” he explained. “The irregular faces that are the result of this, disperse the sound in every direction and distribute it evenly throughout the room – so that one reflection is multiplied into several, and the echo effect disappears, as a result.”

Kasprowicz emphasised that the innovative wall elements weigh between 35 and 200 kilograms, making them heavy enough to reverberate bass tones in the hall. “Not only that,” he said, “but they are also thick enough to absorb sound from the ventilation ducts, behind them.”

The rows of audience seating, he explained, are separated by wood panelling that conceal 10 centimetres of concrete.

“This ensures that the frequencies of even the low-pitched instruments are reflected into the hall,” he said. “The stage itself acts as an amplifier by absorbing vibrations, particularly from instruments, such as cellos and double basses.” This design, he added, ensures that the overall effect is one of a “warm sound”.

im Rutz, Director of Global Platform Management, Tecumseh, spoke on current trends in the United States and how the regulation, shaped by trends, is driving R&D among companies. “In mature markets, like the USA,” Rutz said, “retrofits probably account for 70% of installs. It’s one reason why the most recent energy regulations are constructed to include minimum standards on retrofit systems.

In nations with higher GDP growth, the retrofit percentage is certainly lower, but is often still significant, 30% or more.”

Rutz said that while these new regulations do drive R&D, the challenge for companies is working with different agencies to ensure that demands are not contradictory. He gave an example of how the US Department of Energy (DOE) may mandate minimum efficiency levels while the Environmental Protection Agency (EPA) may dictate the use of refrigerants that are inherently less efficient. “[The] Industry is left to figure out how to reconcile the competing demands,” he said, “You can say that regulations motivate companies to be innovative.

Occasionally, federal, state and local governments will offer incentives – tax credits, grants or subsidies. Often these are short term and dependent on the current political party in power and, therefore, are somewhat fleeting in their effects.” He added that utilities may also offer various incentives to promote the use of a more efficient product and that most probably there is greater incentive to adopt efficiency gains than eco-friendly content.
