Comparison Between Dubai Green Buildings Regulations & LEED

Written by : Published in Blog

Launched in March 2000, Leadership in Energy and Environmental Design (LEED) is globally recognized as the first rating system for green buildings. The Dubai Green Building Regulations, however, are set of regulations that are imposed on all new buildings in Dubai on March 2014 with the purpose of improving the performance of buildings in Dubai by reducing the consumption of energy, water and materials, improving public health, safety and general welfare and by enhancing the planning, design, construction and operation of buildings to create an excellent city that provides the essence of success and comfort of living.

Despite the 14 years difference and the different structure and categorization approach, both LEED and the Dubai Green Building Regulations share similar environmental topics (See Table 1) such as Transportation, Ecological enhancement, Construction impacts management, Light pollution, Heat Island, Noise pollution, Ventilation, Air quality, Smoke control, Interior lighting, Thermal comfort, Water saving, Renewable energy, Energy saving, Conserving and extending buildings and materials life, Green buildings, and Waste management , as they all address the need for more sustainable buildings. However there are seven topics, that didn’t get the same level of attention in both standards either because of its relevance to the local context or its significance compared to other dominant issues.

LEED, for example, formalized in its latest version LEED V4.0 the need for formal cross-discipline coordination in order to support high-performance, cost-effective project outcomes through an early analysis of the interrelationships among systems. The same is not explicitly mentioned in Dubai green building regulations however most likely, it will be considered in future updates to the regulations as the green buildings practices become more mature among the industry professionals.

Natural system conservation is another topic which explicitly recommended in LEED in both Sensitive land protection credit and Site development - protect or restore habitat however no direct citation to specific regulation that refers to the same topic.

In terms of incorporating the special needs in the buildings requirements, Dubai Green Building regulations highlighted the importance of complying with Dubai Municipality Building Regulations, Administrative Resolution No.125-2001with regard to Special Needs. However, LEED didn’t explicitly include special needs provisions as requirements towards achieving any prerequisite or credit.

Rainwater management is extensively covered in LEED in rainwater management credit under the sustainable sites credits category. However, as expected, rainwater management is not highlighted in Dubai Green Building regulations due to the obvious reasons of rainwater scarcity in the region.

Another topic that is differently handled in both systems is the water management. While LEED focused on water saving through the water efficiency credit category, Dubai Green Building regulations gave equal attention to water quality and water saving. With respect to water quality, Dubai regulations focused on the local issue of the Legionella bacteria in Water Quality sections 406.01 Legionella Bacteria and Building Water Systems and 406.02 Water Quality of Water Features. Water saving is covered extensively in section six Resource Effectiveness: Water.

Vertical movement is another area which got more focused coverage in Dubai Green Building Regulations than LEED. With the intensity of high buildings and the dependence on vertical development, it is expected to give more attention to elevators and escalators efficiency due it is significant share in the overall building’s energy use. Accordingly, it has been covered in details in section five - Conservation and Efficiency: Building Systems (502.03 Elevators and Escalators).

One last point that also unequally covered in both standards - Conserving and extending buildings and materials life. While LEED gave specific attention towards extending the service life of buildings and materials in the Building life-cycle impact reduction credit, Dubai green building regulations focused on its seventh section - Resource Effectiveness: Materials and Waste on sustainability of new buildings and no specific reference was made to preserving existing buildings or materials.
