SAP (Standard Assessment Procedure)

A SAP (Standard Assessment Procedure) calculation is a method used to evaluate the energy performance of new residential buildings. It assesses various factors influencing energy efficiency, including building fabric, heating and hot water systems, ventilation, renewable energy use, and occupancy patterns. The calculation results in a SAP score and a Predicted Energy Assessment (PEA), indicating the building’s energy efficiency and estimating annual energy costs and carbon emissions. SAP calculations are essential for ensuring compliance with building regulations and promoting sustainable building practices.
