SAP Calculations & EPC’s

Over the last 60 years we have gained considerable experience in the design of mechanical & electrical (M+E) services installations for residential accommodation projects, including social housing developments for various Local Authorities and Housing Associations, as well as private houses and flats. As part of the design process our engineers undertake SAP calculations to demonstrate compliance with current building standards. These calculations look not only at the thermal transmittance of the proposed structures but also at thermal bridging and construction detailing which can have a significant impact on the energy efficiency of each property. All SAP calculations and EPCs are generated by one of our approved energy assessors using Elmhurst Energy Software, which is independently checked and approved by the Government and compliant with current regulations.

As well as meeting and often exceeding current building standards, many of our clients are looking to achieve increased levels of sustainability as part of their new development. The current sustainability standard our clients typically require is ‘Silver Active’, with elements of the ‘Gold Active’ standard achieved on several projects. On completion of each residential project we reassess the energy performance of the properties based on actual construction details and issue EPCs and Sustainability Labels for each individual property.
