What is a SAP?
A SAP (Standard Assessment Procedure) is a calculation carried out for new builds, Conversions, some extensions and Refurbs. It is a calculation for modelling your design, in correlation to a regional average dwelling and checking compliance with National CO2 targets.
The Calculation is carried out using design drawings, or even planning drawings, which are in accordance with building regulations (Approved Document Part L in England and Wales). To show compliance, the Dwelling Emission Rate must be equal to or better (lower) than the target. Conversions, Extensions and Refurbs do not need to meet this.
Why only ‘Some Extensions’?
Building regulations require that new glazing should account for no more than 25% of new floor area.
Of course, many extension designs will propose more than this, and therefore will not comply to this rule and therefore require a specialised array of SAPs, we at WM Diagnostics are able to help solve this problem for you.
