BREEAM – Environmental Assessment and Swimming Facilities Dr Ben Cartmell ASA – Pools for the Future Seminar Manchester Town Hall, 9 th April 2008
The next 45 minutes Why BREEAM? The Environmental Assessment Consortium Introduction to BREEAM and future changes How to optimise a BREEAM score The Bespoke BREEAM process Associated considerations
Why BREEAM? Building Research Establishment Environmental Assessment Method Aims: Improve environmental performance of buildings Improve internal environment for occupants
BREEAM – An Introduction Number of buildings Regulatory minimum Minimal BREEAM Aspirational
Why BREEAM? Planning Policy PPS22 Renewable Energy PPS1 Planning & Climate Change (consultation) The London Plan / The Mayor’s Energy Strategy / ODA EPBD Building Regulations Part L Energy Certification / Labelling Code for Sustainable Homes (Buildings?) Building a Greener Future: Towards Zero Carbon (Consultation)
The Environmental Assessment Consortium Rickaby Thompson Associates Ian Orme Catherine Arotsky Kathryn Greatorex Rachael Wilson Southfacing Services Ltd Ben Cartmell Lucy Harris Rimante Okkels Gale & Snowdon Architects David Gale Alan Pither Bespoke BREEAM BREEAM International BREEAM Offices BREEAM Schools BREEAM Retail BREEAM Further Education BREEAM Industrial BREEAM Prisons Code for Sustainable Homes EcoHomes LEED BRE Training
The EAC BREEAM Operation Over 220 assessments (complete or in progress) Over 100 live projects Workload growing rapidly International projects underway Assessment team expanding
Bespoke BREEAM example projects
BREEAM International Client: Dubai Maritime City / BRE Development: Office, Retail, Industrial & Residential. Bespoke BREEAM assessment on five towers. Assistance to developer and BRE in developing a BREEAM standard for Dubai.
BREEAM Scoring Management Health and Wellbeing Energy Transport Water Materials Land Use Ecology Pollution Management Health and Wellbeing Energy Transport Water Materials Land Use Ecology Pollution Assessment Credits Environmental Weightings Single Score Issue Category Scores PASS GOOD VERY GOOD EXCELLENT BREEAM Score
BREEAM Scoring Management Health & W’being Energy Transport Water Materials Land Use Ecology Pollution 15 (0.75%) 15 (0.83%) 25 (1.0%) 05 (0.71%) 10 (0.58%) 15 (1.25%) 15 (1.07%) Environmental Weightings
BREEAM in the design process Design Consultancy: Pre-assessment works Formal BREEAM assessment Formal Assessment review Final Certification by BRE Post Construction Review Outline Design (A-C) Detailed Design (D) Late design (D-E) Post Construction (H)
BREEAM in the design process Specific credit consideration
Optimise Management Credits Commissioning Whole Life Costing Building Users Guide Construction Site Impacts –Considerate Constructors Scheme –Construction Waste e.g. BRE SMARTWaste TM System –Monitoring of site CO 2 (site energy and transport), water and control of dust and noise.
Optimise Health & Wellbeing Credits Indoor noise (requirements for specific functional areas) 80% of relevant areas need to be adequately daylight Glare Control Openable windows in order to ensure a potential for natural ventilation Air pollution – location of air inlets
Optimise Health & Wellbeing Credits cont. Minimising risk of internal air pollution 40m 2 Lighting zones (4 workplaces) Thermal zoning Openable windows CIBSE lux levels Occupant controllable blinds Good daylighting
Optimise Energy Credits Improvement over building regulations U-values better than current Building Regulations Sub-metering of major energy uses Tenancy sub-metering Pool covers (?)
Optimise Transport Credits Green Transport Plan Minimise car parking/occupant ratio Provide secure and sheltered cycle locking spaces and facilities for cyclists
Optimise Water Credits Dual flush WCs Waterless urinals and WCs PIR controls Spray or Aerating taps <9litres/min showers Rainwater and Greywater usage Automatic water shut off systems Sanitary supply shut off Water recycling including pool backwash (?) Install a water meter !!
Optimise Materials Credits Refurbishment rather than new building Provide storage area for recyclable materials Use of recycled aggregate material (for fill, hardcore etc) Use of A rated materials from the Green Guide to Specification or use ENVEST Design for robustness 2008 Update
Optimise Materials Credits cont. Responsible Sourcing of Materials Use materials with suitable sustainable certification Timber should be certified under a recognised scheme, FSC and PEFC are best Other materials should be EMAS or ISO14000 compliance Credit is assessed based on proportion of certified materials Tiered structure favours timber i.e. maximum credits cannot be achieved with non-timber construction
Optimise Land-use and Ecology Credits Careful site selection Assess before on-site work commences Identify contaminated land Involve an appropriately qualified Ecologist Protect existing ecology Promote species diversity, native species, habitat creation Biodiversity management
Optimise Pollution Credits Specify use of insulation materials with zero ODP and low GWP Install oil interceptors No refrigeration Build in an area of low flood risk and/or mitigate any flood risk Use of locally generated renewable energy Low NO x boilers

In Summary Most benefits taken through early consideration of BREEAM. Use your assessor – they are there to provide guidance and to work with the project team. Major changes are coming with tighter standards. BREEAM should not be considered in isolation. BREEAM should be a collaboration between those setting the targets and those designing to the targets. ASA / Authorities – What are your specific issues?
