References to Industry Guidance and Codes • CIBSE: ventilation rates, lighting levels, legionellosis, thermal comfort, energy modelling, commissioning. • HVCA: Maintenance and commissioning requirements. • Environment Agency: Pollution, ecological protection. • BSRIA/CIRIA/BRE: Commissioning regimes; Construction site management; Construction waste, construction materials, energy management • Considerate Constructors Scheme and other similar independently auditable schemes • FSC/PEFC: Timber certification
Regulatory minimum Number of buildings Mass market Minimal Aspirational Environmental Standards
What is BREEAM? Which building types can be assessed? • Homes • Crown Courts • Offices • Shopping Malls • Job Centres • Light Industrial Buildings • Heavy Industrial Buildings • Schools / FE • Health Buildings • Sports Facilities • Prison House Blocks • Libraries
Types of BREEAM Assessments Scheme D&P Fit-Out PCR M&O Offices Schools Retail Industrial Healthcare Bespoke
The stages of the BREEAM assessment
• Covers: • New build • Major refurbishments, i. e. building works that would significantly change the environmental performance of the building, like changing the windows, substituting part of the fabric, adding insulation, changing the services • Extensions • Existing buildings in operation

How do you get the higher BREEAM ratings? • • • Early Forward planning Know BREEAM Build relationships Capitalise on project opportunities – Cost effective credits – Consider weighting • Takes time • Pre-Assessment Estimator BREEAM
The price of sustainable schools • BRE and Faithful+Gould – funded by BRE Trust and DCSF • Information Paper IP 1/08: ‘The price of sustainable schools: how much does it cost to achieve BREEAM schools ratings? ’ • Summary of the capital cost implications of achieving BREEAM Schools ratings and low/zero carbon for: – Primary school – Secondary school • IP now available from BRE bookshop £ 9 www. bre. co. uk/brebookshop
Summary of results • Percentage increase in capital cost to achieve a BREEAM Schools rating: Good Very Good Excellent Zero/low carbon 0 – 0. 2 0. 5 – 0. 8 1. 4 – 2. 5 4. 5 – 7. 6 2. 1 – 9. 8 0 – 0. 1 0. 2 – 0. 7 1. 0 – 2. 6 4. 1 – 5. 6 2. 7 – 15. 3 Pass Primary school Secondary school
Putting a price on sustainable schools • Publication FB 15: ‘Putting a Price on Sustainable Schools’ • Detailed outline of capital cost per BREEAM Schools credit and cost of low/zero carbon solutions for two case studies: – Primary school – Secondary school • Available April 2008
Any questions?
Scope of BREEAM FE • All further education / adult / vocational colleges, standalone sixth form buildings and 14 -19 schools with vocational facilities. • The LSC has stated: ‘To qualify for LSC capital funds all proposals will need to address Sustainable Development by ensuring that the completed development meets the criteria to achieve 'Very Good' Building Research Establishment Environmental Assessment Method (BREEAM) rating. ‘
Further Education Tool
Credit Criteria Function Areas Applicability of the credits: whole site / function area
BREEAM update 2008 • From May ‘ 08, BREEAM Schools and BREEAM FE will be incorporated in one scheme, BREEAM Education • Filtered credits • One assessment tool / one manual • This might also include BREEAM HE – when developed
Pembrokeshire College
BREEAM – Bespoke Assessments • Area weighted – Whole building credits are most valuable and offer best value – Specific ‘Area’ credits can often be of low value – FMSDG identified the ‘best value’ credits to be targeted – Now to be BREEAM FE – semi Bespoke – still area weighted
BREEAM – The important bit • Every credit must be robustly evidenced before it can be awarded • Design Team & Client responsible for providing evidence for all credits to be pursued • Pembrokeshire College evidenced in 3 weeks!
Excellent Wasn’t easy! • 100% of credits weren’t available • Several site related BREEAM credits not fully achievable – Transport Links – didn’t fit the BREEAM mould – Ecology – not contaminated! • Some BREEAM credits not available due to the design/specification – Re-used Facades & Structures – Pollution (NOx)
Pembrokeshire College – How Excellent was achieved Highly sustainable basic design • • • Low energy use and renewables Water efficient Re-use of land Good location Good contractor Additional Requirements • • • Ecology Further water efficiencies Transport

Management, Water & Waste High level of site management specified of the Contractor. Client commitment to consultation and publication of information. Water Leak Detection system through BMS. Significant space for recycling storage of as part of campus recycling programme.
Energy, Pollution & Ecology Sedum Roof attenuates water & contributes to the ecological value of the site. Focus on lighting and thermal comfort control & zoning reduced overheating and electricity use. Predicted 6. 99% improvement in Carbon Emissions beyond the Part L Building Regulations Requirement. Air conditioning with leak detection system. Super Low NOx (nitrous oxide) Boilers
Key Lessons Start Early Client Commitment Campus-Wide Future-Proof
What other elements / issues would you cover in a Higher Education environmental assessment? • Some issues to be considered: à Specific functions: Laboratories, others? à Transport patterns – open longer hours? à Car parking à Use of facilities for conferences, lectures, etc? à Commercial scale catering facilities à Campus-wide issues à Others…?
