Residential Conversion, Barn Conversion ,Change of Use
A SAP Calculation will be required to demonstrate compliance for a barn conversion, or a change of use from a commercial property to a residential dwelling, or from a single dwelling into flats.

Psi-Value Calculations Thermal Bridging modeling
From the 15th June 2022 ,Building Regulations Part L 2021 and SAP 10 come into effect and one of the changes will be removal of the option to use Accredited Construction Details for the thermal bridging in a building
Thermal bridging is the movement of heat across an object that is more conductive than the materials around it. Thermal bridging can be a major source of energy loss
