FAQ
As with new build dwellings, the SAP Calculations assess overall thermal efficiency whilst also determining the amount of energy that will required for the internal services such as heating, cooling, lighting and hot water systems. The SAP Calculation also determines carbon (CO2) emissions. Unlike new build properties conversions do not have to fall under any prescribed limit.
As well as demonstrating compliance with Part L1B of the Building Regulations the SAP Calculation is used to produce the Energy Performance Certificate which is required as part of the Building Control sign off procedure whilst also being required for any marketing of the property (for sale or rent).
