Standard Assessment Procedure - What You Need To Know
SAP stands for 'standard assessment procedure'. SAP calculations are designed to measure the energy performance of all new dwellings, conversions and extensions.
You need these calculations to make sure your building complies with Part L Wales.
It is recommended that you get them as early in your project as possible, so if your building should fail, our team can advise you on how to improve.
The SAP methodology is broadly the same as in England however different thermal standards apply for Wales.
Whilst the Dwelling Fabric Energy Efficiency (DFEE) target is not applicable here, the elemental U-Value limits are stricter in Wales.
The main compliance metric overall remains the Dwelling Emission Rate (DER). However, the Target Emission Rate (TER) standards are stricter than in England, often requiring a form of renewable energy.
UKBC offers both L1A and L1B SAP calculations for new builds and extensions and conversions respectively.
