Sustainability LEED vs BREEAM
standards saying that about 32 of the LEED credits will be mandatory according to the EHS [Environment, Health and Safety] standard – just below the Silver rating – and all EHS buildings are monitored post occupancy to ensure they do operate in a sustainable fashion according to the design, and deliver the benefits that the design promises. ‘So although this has just been an interim response
to Sheikh Mohammed bin Rashid al-Maktoum’s decree, it’s very LEED-focused and has done some of the things that LEED and BREEAM failed to do, such as the post-occupancy monitoring.’ Interestingly, Dubai World has publicly said every
region should be creating a rating system to suit its own needs. Nunn adds that despite BREEAM Gulf’s weighting
system being specifically tailored to the area and having a high percentage of water-related credits, LEED is capturing more market share and winning more projects, primarily for two reasons: ‘It’s just a cultural thing, but the Middle East is actually served by a lot of Americans so they’re preferring the LEED standard and promoting it. ‘But, more importantly, LEED has penetrated the regulatory frameworks of Dubai, with Dubai World
mandating the use of LEED in each zone, allowing LEED to capture that market share on the back of regulatory reforms which are proceeding at pace in the United Arab Emirates, as well as winning the backing of key players. ‘BREEAM Gulf remains a voluntary standard in a
market that’s rapidly incorporating aspects of LEED into regulations. BRREAM hasn’t been pushed by a regulatory body or by key development authorities, so it’s lost a lot of market share in Dubai.’ But there are downsides to LEED, says Twinn, who
argues that it is still too costly compared with BREEAM. Furthermore, LEED is tailored for large projects and geared towards conventional systems. It has also been accused of penalising innovation, although the US Green Building Council has added innovation credits to address this issue, he adds. LEED has also been criticised for being too
complicated and not thorough enough, relying too heavily on the US supply chain and operating a long and complex ‘paper chase’ to get everything signed off centrally, says Twinn. In comparison, BREEAM is considered to be of a
marginally higher standard and can be adapted more easily to different regions and countries, as well as
Left to right: Australia’s Dubai Pearl development achieved a LEED Gold pre-certification; a mixed-use scheme in India that’s aiming for a LEED Platinum; Pricewaterhouse Coopers’ offices are the first in London to achieve BREEAM Outstanding; Brighton and Hove Albion Football Club should achieve a BREEAM Very Good.
