SAP ASSESSORS
The Standard Assessment Procedure (SAP) is the UK Government’s National Calculation Methodology for assessing the energy performance of dwellings. Its purpose is to provide accurate and reliable assessments of dwelling energy performances that are needed to underpin energy and environmental policy initiatives.
SAP Assessments
The updated SAP:10 was released in June 2022 as part of the government’s commitment to increase the accuracy of SAP. This new update contacts the updated Part L of the Building regulations and incorporates various changes to the methodology including updated fuel prices, CO2 emissions and primary energy factors. SAP was developed by the Building research establishment (BRE) in 1992 as a tool to help deliver energy efficiency policies and provides a framework for calculating the energy consumption of a dwelling.
Do you need a SAP assessment carried out?
There is no escaping it! If you have a new residential development or conversion Building Regulation compliance requires you to have a SAP assessment on the property. This ensures the development meets both the carbon emissions and fabric performance standards set out in Part L of the Building Regulations. Good news is Stickland Wright can help you.
What is Part L of the Building Regulations?
As of 2022/2023 some key parts of the building regulations have been updated. Part L (fabric performance) deals with the thermal performance of the external envelope of a building. As buildings become increasingly better insulated and airtight, it becomes more important to consider internal air quality and the risk of overheating from the sun.
What does a SAP cover?
When we produce a SAP report we assess how much energy a new dwelling will consume. SAP’s are based on standard assumptions for occupancy and behaviour but it does deliver a apples for apples comparison for dwelling performance on new dwellings. It demonstrates building regulation compliance and produces EPC’s all needed in order to be able to market a new dwelling, build or conversion.
SAP quantifies a dwelling’s performance in terms of: energy use per unit floor area, a fuel-cost-based energy efficiency rating (the SAP Rating) and emissions of CO2 (the Environmental Impact Rating). These indicators of performance are based on estimates of annual energy consumption for the provision of space heating, domestic hot water, lighting and ventilation. Other SAP outputs include estimate of appliance energy use, the potential for overheating in summer and the resultant cooling load.
To produce a SAP report the assessor requires all build up and construction information from the Architect, this process can be time consuming but by running the assessments in house our Stickland Wright SAP assessors work with the Architects to deliver a seamless assessment process. Saving our clients time and money.
