Abu Dhabi Cooling Manual Targets Oversized AC Costs Without Adoption Date
Abu Dhabi’s Department of Energy launched a Cooling Load Manual for new buildings, saying oversized air-conditioning systems can raise equipment and electricity costs. The guidance includes a verification tool for developers and designers, while the public record still lacks enforcement penalties, a mandatory adoption date or measured savings from completed projects.
Abu Dhabi Cooling Manual Covers New Projects
Abu Dhabi's Department of Energy has launched the Abu Dhabi Cooling Load Manual, giving developers, designers and government entities technical guidance for sizing air-conditioning systems in new buildings.
The department said the manual supports the Abu Dhabi Energy and Water Efficiency Strategy 2030.
It is aimed mainly at new developments, but the guidance can also be applied to retrofit projects and reviews of existing systems.
Economy Middle East reported that air-conditioning systems account for about 60–70 percent of electricity consumption in UAE buildings, while those systems are often oversized by 25–35 percent.
The department said better sizing can cut installed air-conditioning costs by up to 35 percent.
Economy Middle East put that potential saving at AED560 million each year across all new buildings in Abu Dhabi.
Villas Could See Lower Equipment And Power Costs
Economy Middle East reported that a residential villa could see a reduction of up to AED56,000 in air-conditioning equipment cost, along with lower connection fees and electricity-bill savings of up to 25 percent.
Ahmed Mohammed Al Rumaithi, undersecretary of the Abu Dhabi Department of Energy, said the department's work is part of a broader effort to build a more efficient, resilient and sustainable energy system in the emirate.
The manual addresses oversizing by giving clearer methods for calculating cooling loads and selecting equipment.
It also points designers towards more accurate assumptions, lower safety margins, better treatment of load diversity and earlier use of passive design measures such as orientation and shading.
The Department of Energy said the guidance can be used from early concept through detailed design, before equipment is purchased, connection fees are set or building systems are locked into project budgets.
The department identified proper zoning and more accurate heat-gain assessment as design steps that can cut cooling demand when they are integrated early in the process.
Verification Tool Benchmarks Cooling Calculations
The Department of Energy also developed a Cooling Load Verification Tool.
The department said the tool lets developers, designers and government entities benchmark cooling calculations against the manual, identify possible overdesign and estimate potential savings.
The guideline aligns with Abu Dhabi codes and international standards, including ASHRAE and CIBSE.
Developers, designers and government entities can use the verification tool to compare proposed cooling loads with the new manual.
Al Rumaithi said the manual is intended to help stakeholders in construction and urban development adopt more efficient solutions, improve energy demand management and use resources more effectively.
The Department of The public record leaves enforcement penalties, a mandatory adoption date, project-level compliance targets, or measured energy savings from buildings already designed under the new manual undisclosed.
