< Previouswww.mepmiddleeast.com30 MEP Middle East | December 2024 DATA CENTRES generation becoming an essential part of the energy mix. At the start of 2024, the Dubai Electricity and Water Authority (DEWA) launched the D33 Industry-Friendly Power Policy, enabling manufacturing, agritech, and data centres to build larger solar systems than permitted under the Shams regulation (capped at 1.2MW). This supports reduced energy costs and Dubai’s decarbonisation goals. With over 100 data centre facilities in operation or under construction across the UAE and Saudi Arabia, on-site solar rooftops and ground-mounted solar installations could significantly contribute to their energy and cooling requirements, minimising costs. To manage demand spikes, data centres can also utilise tailored battery storage, benefiting from a flexible, scalable ‘as-a-service’ model for energy storage. Despite these challenges, the region’s data centre market is growing rapidly, driven by increased digitalisation, regulatory demands, and government support. IMPROVING ENERGY CONSUMPTION AND SUSTAINABILITY OF DATA CENTRES Ironically, one area driving the sharp rise in data centre consumption could also offer solutions. Achieving a sustainable balance between digitalisation and decarbonisation requires a focused strategy that integrates “ To manage demand spikes, data centres can utilise tailored battery storage, benefiting from a flexible, scalable ‘as-a- service’ model for energy storage” from the International Energy Agency (IEA), indicate that data centres contribute nearly 1% of energy-related greenhouse gas emissions. Hyperscale data centre facilities typically require energy capacities of 20- 50MW and use up to five million gallons of water daily. CHALLENGES FOR ENERGY CONSUMPTION WITHIN UAE DATA CENTRES The UAE has a particularly hot desert climate, scarce in water, which presents a unique challenge for data centres. These operations already produce a lot of heat and require effective cooling for optimal performance. With summer temperatures regularly exceeding 40 degrees celsius, novel cooling approaches are needed, with distributed solar power digital innovation with environmental responsibility. Here are three ways data centre operators in the region can mitigate environmental impacts while adopting advanced technologies: • Data Handling: Artificial intelligence can be used at data centres as part of energy efficiency measures to optimise energy consumption, making real-time adjustments to electricity usage and cooling based on demand. Advanced data monitoring and analysis can improve the distribution of cooling across data centres, minimising energy use while maintaining performance. • Cooling and Efficiency: Data centres Unlike other industries where digitalisation helps reduce emissions, data centres can, paradoxically, contribute to higher carbon emissions if not managed sustainably MEP_Dec2024_28-31_Data Centres_13444387.indd 30MEP_Dec2024_28-31_Data Centres_13444387.indd 3025/11/2024 17:0725/11/2024 17:07www.mepmiddleeast.comDecember 2024 | MEP Middle East 31 DATA CENTRES Using renewable microgrids or distributed solar generation allows data centres to integrate with the grid while keeping carbon emissions in check primarily use air cooling and liquid cooling methods. Air cooling involves systems like CRAH (Computer Room Air Handlers) with chilled water or CRAC (Computer Room Air Conditioning) units using refrigerants. Liquid cooling, on the other hand, involves systems such as Coolant Distribution Units (CDUs) and rear door heat exchangers to cool specific components or submerge entire racks in cooling fluids. While combining these methods is highly effective, it requires significant initial investment. Many data centres are thus opting for “Cooling-as-a-Service” solutions, providing cooling without large capital expenses. • Renewable Power: Renewable energy is crucial to prevent data centres from becoming a major emissions source. Using renewable microgrids or distributed solar generation (such as solar rooftops) allows data centres to integrate with the grid while keeping carbon emissions in check. According to IEA data, Amazon, Microsoft, Meta, and Google are the four largest corporate purchasers of renewable energy PPAs (Power Purchase Agreements). Amazon Web Services, for example, already operates a fully renewable-powered data centre in Bahrain. These companies recognise the social, environmental, and economic advantages of using renewable energy for data centres. As energy demand for next-generation ICT rises, balancing this need with renewable energy adoption and energy efficiency improvement is essential. Managing energy and data demands in data centres will be vital for meeting regional and international Net Zero targets. Digitised energy management systems, decentralised renewable energy infrastructure, and energy efficiency ‘as- a-service’ models are key components for reducing costs, lowering emissions, and providing scalable performance.

These spaces are not just rooms filled with advanced technology; they require precise engineering solutions that prioritise safety, efficiency, and patient care. The unsung heroes in these high-tech spaces are the MEP systems that make it all work. This piece draws insights from a whitepaper by RTM Engineering Consultants that provides invaluable information about the critical importance of MEP systems in the effective functioning of MRI suites. THE IMPORTANCE OF MEP SYSTEMS IN MRI SUITES As medical professionals increasingly rely on MRI for its precision and non-invasive nature, the significance of robust MEP systems to support the safe and effective operation of MRI suites cannot be overstated. The intricate interplay of MEP systems ensures that the sophisticated technology within MRI suites functions optimally. THE BASICS OF MRI SUITES An MRI scanner uses a powerful magnet to create an intense, stable magnetic field— usually 0.5 tesla to 3.0 tesla, roughly a thousand times the strength of the Earth’s magnetic field. An MRI scanner utilises the strong magnetic field, as well as radio frequency (RF), to look inside the body during the imaging process. An MRI suite typically consists of three critical areas: Magnet Room – An RF-shielded room that houses the MRI scanner. Operator Control Room – A space that contains the operating console and emergency discharge unit and provides a visual link between the operator and the magnet room. Computer Room – An equipment room that holds electronics, such as gradient cabinets and systems, to support the MRI scanner. The key to success in these environments? MEP systems that meet the unique demands of each space. MECHANICAL SYSTEMS In MRI suites, mechanical systems play a crucial role in maintaining a controlled environment as MRI scanning is expected to be a seamless operation. Achieving this requires meticulous attention to environmental factors like temperature, humidity, and air pressure. The MRI equipment is sensitive to temperature, humidity, and air pressure. It is crucial for the mechanical systems to meet the technical requirements of the equipment while ensuring a safe and protected environment for patients and healthcare staff within the facility. MEP_Dec2024_32-35_MEPinMRI_13412459.indd 33MEP_Dec2024_32-35_MEPinMRI_13412459.indd 3318/11/2024 14:2018/11/2024 14:20www.mepmiddleeast.com34 MEP Middle East | December 2024 WHITEPAPER Temperature and humidity Within the magnet room, proper temperature is vital for system operation, and MRI suites must have sufficient HVAC systems to regulate the temperature to the equipment vendor’s recommendations. To properly regulate the computer room, supplemental cooling may be necessary depending on the limitations of the base building systems. Due to the complexity of these systems, it is critical to involve HVAC experts. Similar to temperature, monitoring and regulating humidity is very important. Humidification or dehumidification may be necessary to keep the magnet room and computer room electronics within their tolerance levels, based on vendor or manufacturer requirements. The HVAC system must be analysed and tailored to meet the equipment’s needs, whether it be a new or existing facility. Emergency Exhaust MRI scanners use cryogens, usually liquid helium, to cool the magnet efficiently and reduce the power needed to operate it. In the case of an emergency shutdown of the magnet (a quench) and the loss of superconductivity, cryogens escape quickly and pose an immediate safety risk. Cryogen leaks can result in injury, entrapment, and asphyxiation. Dedicated emergency exhaust systems are designed to protect an MRI suite in case of cryogen discharge into the room. Emergency systems activate automatically or when an alarm or sensor is triggered, and cryogen vents quickly discharge gases from the building. Cryogen venting was an important design consideration when RTM partnered with the University of Chicago Medicine and Biological Science Division to install a new 3.0T MRI scanner in its radiology department. The University of Chicago MRI project required meticulous calculations to guarantee patient and staff safety. The installation involved significant building renovations, and RTM oversaw the process to ensure each element of the MRI suite— from shielding to emergency systems— met safety specifications. Air Change and Pressurisation To reduce the amount of dust the equipment is exposed to, all spaces should have positive air pressure unless adjoining areas have different requirements. All MRI spaces need a minimum number of air changes per hour. Air change rate (ACR) criteria should be reviewed for every facility based on adopted national, state, and local codes. ELECTRICAL SYSTEMS MRI equipment must also be protected from electrical interferences that can disrupt the magnetic field and the imaging process. Keeping the equipment running is critical, and it is important to understand that primary and secondary power supply systems, along with proper distribution channels, create the heart of a safe and reliable facility. Lighting MRI room lighting fixtures utilise DC (direct current) power instead of AC (alternating current) power. An MRI scanner produces a radio frequency signal, which must be protected from interference. AC power has been known to result in RF interference and distortion of images. RTM combines sophisticated engineering techniques with in-house lighting design experts. Voltage drop, electromagnetic interference, RF filtering, energy efficiency, and egress lighting are all components of a well-designed lighting system that meets the needs of MRI rooms. As in every hospital care space, lighting levels should be carefully reviewed; RTM utilises in-house lighting designers to run photometric calculations to assure proper light levels. RF Shield MRI equipment requires RF shielding to prevent radio frequencies from entering the magnet room and disrupting the imaging process. RF shields are typically thin sheets of copper foil, aluminum, or galvanised 34343433 MEMEMEMEPMEMEPEPEMMMiMiMiMiMMiMiMiMiM ddlddlddlddlddlddlldddddlddlddld eEeEeEeEeEe Ee Ee Ee EEe asasasasastastastastasastastasastst |||| DeDeDDDDDDDDDeDeDeDeDeDeD cemcemcemcemcemcemcememcemcemcemcemcemcece berberbereberberberberberberberberberer 202020202002020202020202020202 24242424422422222224 MEP_Dec2024_32-35_MEPinMRI_13412459.indd 34MEP_Dec2024_32-35_MEPinMRI_13412459.indd 3418/11/2024 14:2118/11/2024 14:21www.mepmiddleeast.comDecember 2024 | MEP Middle East 35 WHITEPAPER steel that cover floors, ceilings, doors, and windows in an MRI magnet room. Any penetrations into RF-shielded areas (for example, HVAC, power, exhaust, plumbing, and piping) pass through RF filters or waveguides. All ductwork, hangers, and supports within the RF shield must be non-ferrous, as ferromagnetic materials can interfere with MRI operations. Emergency Power and UPS Individual hospitals, along with building codes, determine the type of emergency power MRI equipment will need in the event of a power outage. Hospitals frequently use uninterrupted power supply (UPS) systems to maintain constant power to equipment during an outage or when transferring from one source to another. The UPS helps maintain power when switching to and from generator-backed power. RTM typically utilises a flywheel UPS for imaging equipment that is connected to the emergency generator. PLUMBING AND FIRE PROTECTION SYSTEMS MRI suites require unique plumbing and fire protection systems that meet the facility’s health and safety needs while accommodating the equipment’s distinct specifications. As with all other systems, plumbing must be harmonised to suit objectives for sustainability, patient convenience, project cost constraints, and physical space limitations. Designing plumbing systems around an MRI magnet room without interfering with sensitive equipment is particularly challenging. Water and drain lines must be installed in a way that will not interfere with the RF shield, including passing through RF waveguides and dielectric breaks. All sprinkler system components in MRI rooms must be constructed of non-ferrous materials such as copper, brass, and stainless steel. Careful consideration should be given to piping in adjacent spaces. From MRI suite renovations to building new medical centres, every design decision in healthcare impacts patient care, facility operations, and cost. MEP designs must be tailored to ensure easily maintainable, energy- efficient systems that support long-term cost savings. This approach is driven by an engineering strategy that prioritises listening to client needs, understanding the unique requirements of each facility, and overcoming challenges throughout the process. The emergency power requirements for MRI equipment during power outages are determined by individual hospitals and local building codes The intricate interplay of MEP systems is essential for optimal operation of MRI suite technology MEP_Dec2024_32-35_MEPinMRI_13412459.indd 35MEP_Dec2024_32-35_MEPinMRI_13412459.indd 3518/11/2024 14:2118/11/2024 14:21www.mepmiddleeast.com36 MEP Middle East | December 2024 PROJECT PRECISION ENGINEERING We speak with Meraas to uncover the advanced engineering and sustainable strategies behind the BVLGARI Lighthouse project Please share some key details about the project, including the main contractor and lead consultant?
