Description of the tool
The method of calculating the SAP rating is set out in the form of a worksheet, accompanied by a series of tables. A calculation may be carried out by completing, in sequence, the numbered boxes in the worksheet, using the data in the tables as indicated. Alternatively, and for ease of completion, a computer program approved for SAP calculations by BRE can be used (and a few other companies are authorised by the Government to issue energy cost ratings and CIs, because they use software that has been approved by BRE and they have in place quality assurance systems) which results in a SAP rating and CI certificate bearing the official SAP logo.
A full SAP rating requires data entry of over 108 items however a basic SAP rating can be calculated using much less data. Although accuracy is lost when summarising information, SAP values calculated are useful as an assessment and to allow comparisons between dwellings and UK Government approved.
Adaption to the local context is not necessary since the tool is designed to cover all housing in the UK.
