Energy Assessment

At BM3 we will carry out Standard Assessment Procedure (SAP) the methodology used to assess and compare the energy and environmental performance of dwellings. Its purpose is to provide accurate and reliable assessments of dwelling energy performances that will produce EPC Certificates. SAP quantifies a dwelling’s performance in terms of energy use per unit floor area, a fuel-cost-based energy efficiency rating (the SAP Rating) and emissions of CO2 (the Environmental Impact Rating). This can be used on new dwellings and existing using Design SAP 20212 software.

We have extensive experience within this important area and have worked with many clients and developers achieving high standards of Sap and Building Compliance.

The Government has set a target for the UK to reach net zero in carbon emissions by 2050 and has already identified that improvements to existing homes are required in order to achieve this. It is anticipated that PAS 2035 will need to be adopted for all retrofit improvement programmes in the future. We can guide you through how the process works and the quality standards that should be met when carrying out these works.
