BREEAM – Environmental Assessment and Swimming Facilities Dr Ben Cartmell ASA – Pools for the Future Seminar Manchester Town Hall, 9th 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 Regulatory minimum Number of buildings BREEAM – An Introduction BREEAM Minimal 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 Bespoke BREEAM Ian Orme BREEAM International Catherine Arotsky BREEAM Offices Kathryn Greatorex BREEAM Schools Rachael Wilson BREEAM Retail Southfacing Services Ltd BREEAM Further Education Ben Cartmell BREEAM Industrial Lucy Harris BREEAM Prisons Rimante Okkels Code for Sustainable Homes Gale & Snowdon Architects EcoHomes David Gale LEED Alan Pither 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 Overview • Environmental Assessment Method • Certification scheme • Voluntary • Independent & credible • Holistic • Customer focussed • Credits based BREEAM Scoring • Transport • Water • Materials • Land Use • Ecology • Pollution Single Score • Energy Environmental Weightings • Health and Wellbeing Issue Category Scores Assessment Credits • Management BREEAM Score PASS GOOD VERY GOOD EXCELLENT Environmental Weightings BREEAM Scoring • Management 15 (0.75%) • Health & W’being 15 (0.83%) • Energy • Transport 25 (1.0%) • Water 05 (0.71%) • Materials 10 (0.58%) • Land Use • Ecology • Pollution 15 (1.25%) 15 (1.07%) BREEAM Ratings Pass Good Very Good Excellent Outstanding 25% – 40% 40% - 55% 55% - 70% 70%+ 80%+ (BREEAM 2008) BREEAM Update BREEAM 2008 • Fundamental changes expected • Minimum standards as per CSH • Green Guide to Specification (2008) • Information from May 2008 • Implementation from August 2008 BREEAM Schemes Scheme D&P PCR M&O Offices Schools Retail Industrial EcoHomes Bespoke Fit Out BREEAM in the design process Design Consultancy: Pre-assessment works Outline Design (A-C) Formal BREEAM assessment Detailed Design (D) Formal Assessment review Late design (D-E) Final Certification by BRE Late design (D-E) Post Construction Review 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 SMARTWasteTM System – Monitoring of site CO2 (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 40m2 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 NOx boilers Bespoke BREEAM setup process Bespoke BREEAM Assessment Process Bespoke BREEAM Setup Processes Pre-assessment works / Scenarios Formal Bespoke BREEAM Assessment • Assessment Delivery Report • Updated Status Report / Guidance • Final Assessment Report QA & Certification Post Construction Review QA & Certification The two sides to Southfacing London Reading Energy & Environmental Consultancy Design & Development of Design Tools Social Enterprise Projects Southfacing’s services Energy & Environmental Consultancy • Part L analysis and energy assessments (NHER, SBEM, Tas etc) • Feasibility for low carbon technologies (building and site) • Environmental assessments (BREEAM, Sustainable Code etc.) Software development • Carbon Checker (Southfacing) • Low Carbon Designer (London Energy Partnership / GLA) • Climate Lite (DTI / BRE) • Other at-risk projects….

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? www.southfacing.co.uk [email protected]
