1 B R E E A M Assessing the Environmental Performance of Buildings Roy Stewart Centre for Construction Innovation

2 Introduction What is BREEAM? Aims Building types Key drivers How it works BREEAM as a requirement BREEAM as a commitment Capital Cost Great to go green

3 What is BREEAM? Building Research Establishment Environmental Assessment Method Measures the environmental impact of a building throughout its life

4 What is BREEAM? Provides comprehensive method of measuring environmental performance. Differentiates developments with higher environmental performance Quality mark stating that a building is ahead of regulations. Low running costs and improved health and well being for occupants. Method of demonstrating environmental credentials to funding organisations, client, investor, planning authority etc.

5 Aims of BREEAM BREEAM Number of buildings Regulatory minimum Minimal Aspirational Environmental Standards

6 Types of BREEAM Two main types: - BREEAM for Offices EcoHomes But also: - BREEAM Retail Industrial BREEAM BREEAM Schools NEAT (Health Buildings) Bespoke BREEAM

7 BREEAM Certification scheme Voluntary Independent & credible Holistic Customer focused

8 What does it cover? New houses and flats at the design stage. Existing houses and flats during major refurbishment. Sheltered homes with individual servicing. Sheltered Homes with communal servicing. But not Existing houses and flats. Existing vacant offices New Build and refurbishment Existing and occupied At stages: - Core building performance Design & procurement Management and operation

9 EcoHomes key drives To demonstrate a sustainability commitment to partner organisations e.g. residents, communities, funding organisations, planning authorities Reduced maintenance costs Reduced running costs Provide affordable warmth Healthy and comfortable internal environment Increased level of occupant satisfaction Reduced dependence on private car ownership Outperforms market housing - increased saleability Improved developers image with public and investors

10 EcoHomes - How it works assessment at the design stage single environmental rating performance assessed against a broad range of environmental criteria the award of a visible certificate and detailed report carried out by independent assessors trained and licensed by BRE external or in-house

11 Assessment Stages Stage 1 - Specification Stage 2 - House Types Stage 3 - Site assessment Formal certification Stage 4 - Post Construction Review

12 The issues Performance assessed against a broad range of environmental criteria Energy Transport Pollution Materials Water Land use & Ecology Health and well being

13 The issues - examples Energy Minimise CO 2 emissions Improve the efficiency of buildings over whole life Transport Encourage use of public transport Pollution Reduce potential of pollution/global warming Materials Encourage use of timber from sustainable sources Water Reduce water consumption Land use & Ecology Ecological enhancement of sites Health and well being Improve quality of life

14 Single environmental rating Energy Assessment Credits Transport Pollution Materials Water Land Use and..ecology Health and well being Issue Category Scores Environmental Weightings Single Score EcoHomes Rating

15 Single environmental rating Pass Good Very Good Excellent

16 But why an environmental rating? A B C D E F G Energy Labelling Energy efficiency A = most efficient G least efficient

17 But why an environmental rating? Office of Government Commerce Common Minimum Standards for the procurement of built environments in the public sector Released 12 October 2005 Where a business case for a new programme or project includes a construction element, departments should ensure that this is undertaken with full reference to the CMS Standards for construction procurement mandated with immediate effect

18 But why an environmental rating? An appropriate environmental assessment process such as BREEAM must be carried out on all projects When BREEAM is used all new projects are to receive an excellent rating and all refurbishment projects are to achieve at least very good rating

19 BREEAM as a Requirement English Partnerships BREEAM VERY GOOD and EXCELLENT for all new developments involving their land Office of Government Commerce (OGC) BREEAM rating of EXCELLENT Housing Corporation EcoHomes GOOD mandatory from April 2005 Potentially VERY GOOD from April 2006

20 BREEAM as a Requirement Local Authorities Incorporating Environmental standards as part of supplementary planning guidance. Including in Section 106 agreements Regional Development Agencies SEEDA Sustainability Checklist NWDA are doing the same + Sustainability Guidance Housing Market Renewal Pathfinders Elevate - EcoHomes VERY GOOD on all developments

21 BREEAM as a Commitment Private Developers Countryside Properties is committed to building all of its new homes to a minimum standard of 'Good', with the intention of achieving 'Very Good' on all of its new homes over the next 10 years. NGO s WWF (World Wide Fund for Nature) One Million Sustainable Homes (OMSH) Campaigning for EcoHomes VERY GOOD to be set as the CSB standard

22 Code for Sustainable Buildings (CSB) Sustainable Buildings Task Force (SBTF) recommended the code should be based on BREEAM / EcoHomes ODPM concentrating initially on housing First version due Jan 2006

23 EU Initiatives COMING SOON.. EU Energy Performance of Buildings Directive (EPBD). Modifications to Building Regulations Part L (2005) Energy Performance Certification Early days to know how this will be implemented in the UK May stimulate a market in existing buildings (public buildings initially)

24 What about the cost? Capital Costs Research Social Housing Using Research by Sustainable Homes Published in a document called: A Guide to EcoHomes (2003) Private Housing Putting a price on sustainability - BRE Trust (BRE & Cyril Sweett) 2005 Part of this study considered the capital cost implications of achieving the different BREEAM / EcoHomes ratings

25 Social Housing: Costs to achieve each rating Rating Favourable site Unfavourable site Pass 0 30 Good Very Good Excellent Based on Social Housing compliant with HC s SDS

26 Private Housing: Costs to achieve each rating Rating Good Location Poor Location Pass 0 76 Good Very Good Excellent Based on Private house of 76,000 capital cost

27 RICS Green Value Report RICS makes the commercial case for green buildings 7 reasons why the RICS says green buildings are great to go green Building 28/10/05

28 RICS Green Value Report 7 reasons why the RICS says green buildings are great to go green They secure tenants quicker They bring in higher rents & prices They keep tenants for longer They cost less to operate & maintain They can attract grants & subsidies They improve business productivity They return 10 times the money that you invest in making them green
