SAP stands for Standard Assessment Procedure and it is the United Kingdom government’s procedure for calculating the energy performance of dwellings. These calculations are needed to demonstrate that your building complies with specified energy targets set down in the building regulations.
In a brief overview, that’s basically it.
Sap Assesments are usually required for 3 main reasons
- For all newly built properties.
- For a dwelling change of use, such as modifying a commercial building to residential flats.
- For overglazed extensions|{Sap calculations are usually required for 3 main reasons.
There are two main targets that the sap calculations are required to demonstrate. Firstly that the dwelling emission rate (DER) and the dwelling fabric energy efficiency (DFEE) comply with certain targets.
A good set of building drawings must be given to the Assessor, because all the calculations are done from the building drawings . Your Assessor will advise you of precisely what is needed.
After the calculations are finished, an Energy Performance Certificate or EPC can also be produced.
Your Assessor can provide you with further advice if the calculation show your dwelling isn’t compliant, as well as explain to you which would be the most effective changes to make.
It could be costly if you find out at a late phase in the construction that your building is not compliant. So it’s wise to liaise with the Assessor as early on in the project as possible.
