The Standard Assessment Procedure (SAP) is adopted by Government as the UK methodology for calculating the energy performance of dwellings within Approved Document L1A - Conservation of fuel and power in new dwellings and Approved Document L1B - Conservation of fuel and power in existing dwellings.
The calculation is based on the energy balance taking into account a range of factors that contribute to energy efficiency:
- Materials used for construction of the dwelling
-
Thermal insulation of the building fabric
-
Ventilation characteristics of the dwelling and ventilation equipment
-
Efficiency and control of the heating system(s)
-
Solar gains through openings of the dwelling
-
The fuel used to provide space and water heating, ventilation and lighting
-
Energy for space cooling, if applicable
-
Renewable energy technologies
We are now in a position where we can offer to carry out your SAP calculation for an additional cost starting from £200 including VAT.
