The Standard Assessment Procedure (SAP
Calculation) is the UK Government’s approved methodology for calculating the
energy performance of new built of converted dwellings.
For compliance with Building Regulations PART L
2010, SAP calculations are required for all new dwellings together with the
ones that have been created through material changes of use involving building
work and extensions over certain sizes (consult with your building control
authority for this requirement).
A SAP EPC report is generated through the use of
Government Approved software and technical calculations to produce a Predicted
Energy Assessment (PEA) and an On Construction Energy Performance Certificate
(OCEPC) both of which are reports evaluated from the supporting SAP Calculations.
