SAP Calculations
SAP is the Governments 'Standard Assessment Procedure' for energy rating of
dwellings. SAP, was designed to be included in the 1995 Building Regulations
and it is now a compulsory component in Part L of the Regulations. Every new
house has to have a SAP rating.
SAP is calculated by a procedure contained in the Building Regulations, which
predicts heating, and hot water costs. These depend on the insulation and air
tightness of the house and the efficiency and control of the heating system.
The calculation uses the Building Research Establishment's Domestic Energy Model
(BREDEM).
