EASTLEIGH BOROUGH COUNCIL LOCAL DEVELOPMENT FRAMEWORK Environmentally Sustainable Development SUPPLEMENTARY PLANNING DOCUMENT ADOPTED 5 MARCH 2009 APPENDIX 1: SUSTAINABLE DEVELOPMENT: Technical Guidance CONTENTS Definitions 1. General Sustainable Development 2. Water 3. Energy/CO2 4. Materials and Waste 5. Green Infrastructure 6. Health and Wellbeing 7. Sustainable Management 8. Major Developments DEFINITIONS [The Code for Sustainable Homes This is for for ‘Residential development’ (all new houses and flats but not extensions and conversions nor institutional accommodation). The Code is an environmental assessment method for new homes based upon the BREEAM ‘Ecohomes’ which it replaced (in England) in April 2007. Each development to be assessed against the Code needs to be registered with the BRE by a BRE-licensed Assessor, who is employed by the developer. The development is assessed by the Assessor who awards credits when sufficient documentary proof has been supplied to satisfy each credit requirement. The Code covers 9 areas of environmentally sustainable development, namely: • Energy/CO2 • Water • Materials • Surface Water Runoff • Waste • Pollution • Health and Wellbeing • Management • Ecology There are minimum mandatory standards for Energy/Co2, Water Consumption, Waste, Surface Water Run-off and Materials at Level 1. There are further minimum mandatory standards for Water Consumption at levels 3 and 5. Energy/CO2 has mandatory APPENDIX 1: GUIDANCE: CODE FOR SUSTAINABLE HOMES minimum standards at each of the levels culminating in level 6 which requires “carbon neutral” development. Lifetime Homes compliance is mandatory at level 6 The BRE audits the assessments and awards a certificate according to the final point score. Seven levels are possible (see table 1): RATING Minimum Score Required (%) FAIL < 36 Level 2 36 Level 2 48 Level 3 57 Level 4 68 Level 5 84 Level 6 90 Table 1: Code FSH Ratings Certification is compulsory at both the design stage (interim certificate) and at the post construction review stage (final certificate). A certificate is issued for each individual dwelling rather than for the whole development. Dwellings can be grouped into ‘Code Dwelling Types’ that share the same features and hence receive the same credits to save unnecessary repetition. For more general information about the Code and finding an Assessor refer to the BRE website, link below: The Code for Sustainable Homes, Technical Guide, published by DCLG (October 2008), can be found on the following link: http://www.planningportal.gov.uk/uploads/code_for_sustai nable_homes_techguide.pdf The Code Technical Guide, describes the aim of each category, the number of credits to achieve for each category and whether they are mandatory or optional. It explains the assessment criteria, lists the information that the BRE licensed Assessor will require from the development to demonstrate compliance and describes the assessment methodology for the design stage and post-construction stage and calculation procedures. 2 APPENDIX 1: GUIDANCE: BREEAM BREEAM For ‘Multi-residential’ (institutional accommodation such as student halls of residence or sheletered housing for the elderly) and ‘Non-residential’ devlopment (all other building uses such as offices, retail buildings, schools, industrial buildings etc.) The Building Research Establishment Environmental Assessment Method (BREEAM) is an independent appraisal method to certify the environmental performance of a building. BREEAM Buildings can be used to assess the environmental performance of any type of building (new and existing). Standard versions exist for common building types and less common building types can be assessed against tailored criteria under the Bespoke BREEAM version. BREEAM covers 8 areas of environmentally sustainable development, namely: • Management • Health and Wellbeing • Energy • Transport • Water • Materials and Waste • Land Use and Ecology • Pollution The issues within these areas vary according to the specific assessment model being used but there are a lot of issues in common. One aspect that is strikingly different from the Code for Sustainable Homes (see below) is the BREEAM credits for access to the site, particularly for non-car users and its location in relation to key facilities. To achieve a BREEAM rating, the minimum percentage score (see table 2) must be achieved and the minimum standards (i.e. number of credits achieved) applicable to that rating level complied with. 3 APPENDIX 1: GUIDANCE: BREEAM BREEAM Rating/ Mininum number of credits BREEAM Issue PASS GOOD VERY GOOD EXCELLENT OUTSTANDING Man 1 - Commissioning 1 1 1 1 2 Man 2 - Considerate Constructors 1 2 Man 4 - Building user guide 1 1 Man 9 - Publication of building information (BREEAM 1 Education only) Man 10 - Development as a learning resource 1 (BREEAM Education only) Hea 4 - High frequency lighting 1 1 1 1 1 Hea 12 - Microbial contamination 1 1 1 1 1 Ene 1 - Reduction of CO2 emissions 6 10 Ene 2 - Sub-metering of substantial energy uses 1 1 1 Ene 5 - Low or zero carbon technologies 1 1 Wat 1 - Water consumption 1 1 1 2 Wat 2 - Water meter 1 1 1 1 Wst 3 - Storage of recyclable waste 1 1 LE 4 - Mitigating ecological impact 1 1 1 Table 2: Minimum BREEAM standards Each development needs to be registered with the BRE by a BRE- licensed Assessor, who is employed by the developer. The development is assessed by the Assessor who awards credits when sufficient documentary proof has been supplied to satisfy each credit requirement. The BRE audits the assessments and awards a certificate according to the final point score. Five levels are possible (see table 3): RATING Minimum Score Required (%) UNCLASSIFIED <30 PASS ≥30 GOOD ≥45 VERY GOOD ≥55 EXCELLENT ≥70 OUTSTANDING ≥85 Table 3: BREEAM Ratings 4 APPENDIX 1: GUIDANCE: BREEAM Certification is compulsory at the design stage and is optional at the post construction review stage. A certificate is issued for the whole development rather than for individual buildings. More information including pre-assessment estimators and technical guides for each of the BREEAM assessments can be found on the following website: http://www.breeam.org/ The current models of BREEAM Assessment available are shown in the table 4 below. BREEAM: Healthcare BREEAM Healthcare can be used to assess all healthcare buildings containing medical facilities, and at different stages of their lifecycle. An additional tool BREEAM Healthcare XB also offers a solution for existing buildings in operation. BREEAM: Industrial BREEAM Industrial can assess storage & distribution, light industrial units, factories and workshops at the design stage and post construction. BREEAM: Multi-residential BREEAM Multi-Residential can assess student halls of residence, sheltered housing for the elderly, supported housing and hostel type accommodation at the design stage and post construction. BREEAM: Prisons BREEAM Prisons can assess high and standard security prisons, young offenders institutions, local prisons and women's prisons at the design stage and post construction. BREEAM: Offices BREEAM Offices can assess new build or major refurbishment and existing offices, at the design stage, post construction and in use. 5 APPENDIX 1: GUIDANCE: BREEAM BREEAM: Retail BREEAM Retail can assess new build or major refurbishment, post construction, tenant fit-out, existing (occupied), management and operation. BREEAM: Education BREEAM Education can assess new schools, major refurbishment projects Table 4: The current BREEAM Assessment Models relevant to this document © Copyright Building Research Establishment Ltd 2008 6 APPENDIX 1: GUIDANCE: 1.1 GENERAL SUSTAINABLE DEVELOPMENT 1.0 GENERAL SUSTAINABLE DEVELOPMENT 1.1 Minimum Code For Sustainable Homes and BREEAM Requirements Certification under the Code FSH and BREEAM provides a good indication of a certain level of sustainable development over a broad range of sustainable measures. Where the Council has more specific requirements these may be found within the detail of the assessment methods (specific credits required for a particular issue) or are requirements not specifically covered by the Code FSH or BREEAM. These specific issues are covered in subsequent Essential Requirements in this document. The general sustainable development requirement needs to escalate over the next decade to keep pace with expected Building Regulations changes and the target for Zero Carbon Homes by 2016. The development industry also needs some time to employ new design strategies and use new technologies and materials before the top levels of the assessment methods are required for all development.
