Overview
A SAP assessment models the energy performance of a dwelling and is used to demonstrate the applicable Part L requirements. The useful part is not simply the result: it is understanding which parts of the design are driving it, and resolving them without losing sight of buildability, cost or architectural intent.
Project requirements vary by building type, location and timing. Send us the project information and we will confirm the right assessment route before providing a quotation.
Particularly useful for
- New dwellings and applicable conversions
- Single homes and small residential developments
- Design-stage checks before specifications are fixed
- As-built assessment and coordination of final evidence
