What is a SAP Report?
A SAP report (Standard Assessment Procedure) is used as a means to show compliance with the Current Building Regulations for any new build or renovation project. The report takes into account the buildings insulation levels, heating systems, size, etc. and calculates what the buildings CO2 emissions are. These are then compared to a target CO2 emission rate for the building characteristics and if the actual CO2 levels are lower than this the building passes Building Regulations.
SAP calculations can be used to give an accurate sizing for a heat pump, as they contain detailed heat loss information about the building. The relevant information is contained on the “SAP Work Sheet” and the important figure for Kensa, is line 37 - The Heat Loss Coefficient. A snap-shot of a typical SAP calculation is below:-
Kensa can provide an accurate quotation for the heat pump kit if you send the SAP work sheet to us.
Without a SAP report an initial sizing can be done, based on the floor area of the building, however, we would always recommend a SAP report is forwarded to us to ensure the sizing matches the building load, especially for renovated building where the heat loss is harder to estimate.
