SAP Appendix Q database

This webpage is known as the 'SAP Appendix Q database' and comprises a range of spreadsheets.

Appendix Q of SAP provides a means whereby validated individual branded product performance information can be accessed and used as an adjunct to the SAP calculation. A product’s performance information is determined by testing against a specification that has been agreed by the Department for Business, Energy & Industrial Strategy's (BEIS) NCM contractor, the relevant manufacturer(s) and industry sector representatives. Product data listed in this database may migrate to the PCDB when a new version of SAP, incorporating the relevant calculation process, is released. The data will also remain in the Appendix Q database until obsolete versions of SAP have been withdrawn or where it is impractical to include it within the PCDB.

Product data will be used in preference to any default value to determine the energy performance of the dwelling, providing the product is installed in the dwelling being assessed and can be recognised and identified by the Dwelling Assessor. Acceptance of product data as an input to the NCMs does not denote any form of endorsement, nor does it imply that the dwelling’s energy performance rating is better than that obtained using alternative products.

Below are spreadsheets for various technologies recognised via Appendix Q. Typically, since technologies migrate from the Appendix Q database (this webpage) to the PCDB with new versions of SAP, an Appendix Q spreadsheet is no longer necessary for migrated technologies.
