All new buildings including some Conversions and extensions now require a SAP rating prior to the building stage. The SAP assessment is used to determine if the complies to local buildings regulations for energy efficiency.
Various parts of the UK follow their own buildings regulations with energy efficiency guidance detailed in the following sections;
‘Part L’ for England and Wales
‘Section 6’ for Scotland
‘Part F’ for Northern Ireland
SAP works by assessing how much energy a dwelling will consume, when delivering a defined level of comfort and service provision. The assessment is based on standardised assumptions for occupancy and behaviour. This enables a like-for-like comparison of new dwelling performance against a target building of the same size and shape.
Related factors, such as fuel costs and emissions of carbon dioxide (CO2), can be determined from the assessment. 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
CO2 emissions (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.
We would recommend that the SAP assessment is undertaken early in the design process, this will help to prevent any costly re-design of the dwelling.
A SAP assessment for a new dwelling is a desktop exercise, the client or their designer start by submitting a full set of drawings, plans and the full specifications of the development.
the following is a full list of the information and data required.
Site address and postcode.
Site plan to include orientation of the dwelling(s).
Plans of each storey, normally at 1:100 scale.
Elevations drawings for each elevation.
Sectional drawings of the dwelling.
A written design specification.
