An Energy Statement is a detailed calculation report submitted with planning application which shows that a development will achive the local authority’s emissions target.
New houses or apartment blocks will each need a Standard Assessment Procedure (SAP) calculation to be completed. Any building, which is not a dwelling, will require a Simplified Building Energy Model (SBEM) calculation. These calculations should ideally happen as early as possible in the design stage. They lead to the Energy Performance Certificate (EPC).
