SAP calculations

SAP energy calculations and compliance support for new dwellings and residential building work.

The service

Clear technical work.
Useful outputs.

SAP calculations assess the predicted energy performance of a dwelling from its design information. They are used to demonstrate compliance for new homes and can also be required for conversions, extensions and material changes of use.

We review the drawings and specification, model the dwelling and identify where the design may need adjustment before the final compliance documents are produced.
