S3 Sustainable Design Standards

  • Major and minor residential developments involving refurbishment or extensions are required to achieve a final (post-refurbishment) certified rating of Excellent under BREEAM Domestic Refurbishment 2014 (or equivalent scheme) and must make reasonable endeavours to achieve an Outstanding rating.
  • Major and minor new-build residential developments must achieve a four-star rating (as a minimum) under the BRE Home Quality Mark scheme.
  • All non-residential and mixed-use developments proposing 500sqm or more net additional floorspace are required to achieve a final (post-construction stage) certified rating of Excellent as part of a fully fitted assessment within BREEAM New Construction 2018 (or equivalent scheme), and must make reasonable endeavours to achieve an Outstanding rating. A ‘verification stage’ certification at post-occupancy stage must also be achieved, unless it can be demonstrated that this is not feasible.
  • Major non-residential and mixed-use refurbishment developments are required to achieve a final (post-construction) certified rating of Excellent under BREEAM UK Non-Domestic Refurbishment and Fit-out (or equivalent scheme) and must make reasonable endeavours to achieve an Outstanding rating. The scope of works of the development must include a full fit-out, unless it can be demonstrated that this is not feasible.
  • All developments assessed under BREEAM New Construction 2018 (as required by Part C) and Non-Domestic Refurbishment and Fit-out schemes (as required by Part D) are required to score the following minimum ‘credits’, in addition to the minimum acceptable requirements for a BREEAM excellent rating:
    1. At least 50% of credits on Environmental impacts from construction products (Mat 01);
    2. At least 1 credit on Responsible sourcing of materials (Mat 03), in addition to Criterion E(i);
    3. At least 50% of credits on Construction waste management (Wst 01);
    4. All credits on Water consumption (Wat 01), or a minimum of 3 credits where rainwater and/or greywater recycling is demonstrated not to be feasible;
    5. The second credit on energy monitoring (Ene 02 – Sub-metering of high energy load and tenancy areas), where feasible;
    6. Reasonable endeavours must be made to achieve two credits under the Ene 01 exemplary level criteria, in order to demonstrate zero carbon development; and
    7. BREEAM New Construction only - all 4 credits for Energy modelling and reporting as part of Reduction of energy use and carbon emissions (Ene 01).
  • All developments assessed under BREEAM Domestic Refurbishment 2014 (as required by Part A) are required to score the following credits, in addition to the minimum acceptable requirements for a BREEAM excellent rating:
    1. At least 50% of credits on Environmental impact of materials (Mat 01);
    2. At least 50% of credits on Responsible sourcing of materials (Mat 02); and
    3. All credits on Refurbishment site waste management (Was 2).
  • All minor non-residential new build developments and minor non-residential extensions of between 100sqm and 500sqm are required to demonstrate how all credits for Water consumption (Wat 01) would be achieved under the relevant BREEAM scheme. A minimum of 3 credits must be achieved where rainwater and/or greywater recycling is demonstrated not to be feasible, in order to achieve water credits equivalent to an Excellent standard.
