Learn about BREEAM, a voluntary environmental certification tool, that promotes best practices beyond legislation and improves the performance of buildings. Explore the background, administration process, scoring system, BREEAM schemes, and its comparison to LEED. Discover how BREEAM is applied in convention/exhibition centers and the future of sustainable development legislation.

Going Green – A UK Perspective Presented by Martin Jennings, Partner, Davis Langdon LLP
Introduction Building Research Establishment Environmental Assessment Method Voluntary environmental certification tool for buildings
Objectives Promoting best practice – beyond legislation Improving performance of buildings Benchmarking buildings Stimulating demand for sustainable buildings
Background • Developed by BRE & AECOM • 1990 : BREEAM Offices UK (~30 credits) • 2008 : BREEAM International (>100 credits) • 2009 : BREEAM International updates • 116 000 buildings certified • 710 000 buildings registered
Administration & overview • BRE • Accredit assessor • Provide guidance • Verify recommendations • Issue certificate • Assessors • Advise developer & design team • Liaise with BRE • Assess evidence • Recommend rating to BRE BRE own, maintain, develop and administer
Assessment process • Post construction • Site visit • Assessment meeting • Action list • Final report • Final certificate Mandatory Optional Design stage • Action list • Guidance report • Interim report • Assessment meeting • Interim certificate
Scoring system * weighting & credit numbers vary between schemes
Rating Unclassified Pass Good Very Good Excellent Outstanding 0% 30% 45% 55% 70% 85% 100%

BREEAM UK • Offices • Industrial • Retail • Healthcare • Schools • Education • Prisons • Courts • Bespoke • Data centres • Communities • EcoHomes • Code for Sustainable Homes
BREEAM International 2009 • Minimum standards Specific credits must be achieved to obtain a rating. • Post Construction Review PCR mandatory. Optional certificate at design stage. • Innovation credits Buildings exceed requirements or with innovative feature.
Olympics: Sustainable Development Strategy & Plan Basketball Arena, 2012 London Olympics BREEAM related targets: • Permanent venues to achieve a BREEAM EXCELLENT rating. • Olympic village to achieve Code Level 4 • Minimise embodied impact of materials through use of tools such as BRE Green Guide to Specification • BRE SMARTWaste to monitor/minimise construction and demolition waste.
UK Planning Policy The Government set out in its Building a Greener Future - Policy Statement (July 2007) that new homes will be net zero carbon from 2016. As steps to achieving this target, energy efficiency standards for new homes are to be improved by 25 per cent in 2010 and 44 per cent in 2013 relative to current 2006 standards. The Government also wants to introduce improved energy efficiency standards for new non-domestic buildings, and in its 2008 Budget announced an ambition for all new non-domestic development to be net zero carbon from 2019. (They) are therefore proposing a similar phased improvement beginning with 25 per cent reduction in 2010 and plan to consult on the further trajectory towards zero carbon new non-domestic buildings later this year.
BREEAM v LEED • LEED • Optional Standards • Percentage Thresholds • Based on US Dollars • Niche application in UK • Team involvement BREEAM Legislation/Best Practice Quantitative Thresholds Based on Carbon Dioxide Main application in UK Assessor involvement
BREEAM v LEED There is a lot of hype about the battle between BREEAM and LEED in the UK, but this seems to be unfounded. Both seem happy to co-exist and each has their niche areas or countries. They are even borrowing each other's ideas as they grow. BREEAM will probably always come out on top in the UK, simply because it is imbedded in the system. Government departments require BREEAM ratings of all their buildings; most local authorities require BREEAM as part of planning approval for developments over a certain size. Once projects are underway that aim to be zero carbon, the likes of BREEAM or LEED may have developed to become the global default methods of assessment
CONVENTION/EXHIBITION CENTRES • ACC Liverpool • New facility • BREEAM 2004, Bespoke Assessment, Very Good rating, 58% final score • Credits targeted based on value added within available budget • Difficult to achieve Excellent due to type of building and frequency of use • Did not achieve renewable energy credit • Manchester Central • Remodelled facility • BREEAM 2004, Bespoke Assessment, Very Good rating achieved • Location and budget constrained options
CONCLUSION • BREEAM is well established in the UK and has real credibility • BREEAM is focussed at a holistic level • Unlikely that a convention/exhibition specific model will be produced by the BRE • UK and European development legislation on sustainability and energy use will be more onerous in the coming years • The nature of convention/exhibition centres makes some sustainable solutions economically unviable • Is BREEAM’s holistic approach better than LEED for convention/ exhibition centres?
