New development – sustainable energy information requirements
All development proposals that require a Design & Access Statement should provide information about the proposed energy performance of the development. This can be included either within the Design and Access Statement or as a separate Energy Statement. The level of detail required will depend on scale of the development. Requirements for Major Developments, all other Developments requiring a Design and Access Statement, and stand alone renewable energy proposals are as follows:
Major residential, commercial & mixed-use developments
- State which building regulations the development is to be built to, taking into account changes in the energy requirements of Building Regulations over the build-out period.
- Provide an estimate of the energy demand and CO2 emissions of the proposed development, assuming construction to the minimum energy performance required by the applicable building regulation standards.
- Describe what measures are being included which will reduce the energy demand of the development beyond the building regulations requirement, with quantification of the additional energy expected to be saved and a simple explanation of how this has been calculated. This should include any passive energy measures that have been incorporated into the design.
- Describe what renewable / low carbon energy generation measures are being included, their installed capacity (kW), predicted energy generation (kWh/yr) and associated CO2 savings (tonnes/yr) and a simple explanation of how this has been calculated. State clearly if these have been included to meet building regulation requirements.
- Where required by Core Strategy Policy CS4, provide details of the viability of district heating. Where district heating is being included, provide details of the proposed extent and layout of the network, and arrangements for delivery.
- Provide a concluding section summarising why certain measures were chosen and the additional reduction in energy demand and offset CO2 emissions achieved through the measures being deployed compared with the baseline energy demand and emissions as allowed by the relevant building regulations.
All other developments that require a design and access statement
- State which building regulations the development is to be built to.
- Describe what measures are being included which will reduce the energy demand of the development over and above those required to meet the minimum building regulation standards, including any passive energy measures that have been incorporated into the design.
- Describe what renewable / low carbon / decentralised energy generation measures are being included, their installed capacity (kW) and predicted energy generation (kWh/yr).
Applications for stand-alone energy installations should state their proposed installed capacity (kW), predicted energy generation (kWh/yr) and associated CO2 savings (tonnes/yr). It is also helpful to state the number of ‘households’ equivalent.
