The Department for Business, Energy and Industrial Strategy published on 16 November 2016 a Public consultation on proposals to amend the Standard Assessment Procedure (SAP).
This consultation proposes changes to how Standard Assessment Procedure (SAP) assesses the energy performance of homes.
The SAP is a methodology used to assess the energy performance of homes and thereby helps deliver many of Government’s energy and environmental policy objectives.
The SAP assessment is used for many purposes – including compliance with Building Regulations, and to produce Energy Performance Certificates.
Reduced data SAP (RdSAP) is the methodology used to produce Energy Performance Certificates, which are required at point of sale or rental and used to support policy delivery for many Government schemes, including the Feed in Tariff and the Renewable Heat Incentive scheme.
Depending on policy development, changes to SAP or RdSAP may require consequential changes to legislation, for example relating to Green Deal or the Energy Company Obligation.
It is proposed to make changes in respect of the following technologies or parts of fabric of the house.
Amendment 1 – Carbon Dioxide Emission Factors
Amendment 2 – SAP Heating Regime
Amendment 3 – Distribution Loss Factors for Heat Networks
Amendment 4 – Lighting calculation
Amendment 5 – Thermal bridging
