SAP Appendix Q database
This webpage is known as the 'SAP Appendix Q database' and comprises a range of spreadsheets - see below
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 DECC’s 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 The data will also remain in the Appendix Q database until obsolete versions of SAP have been withdrawn or where it is impractical to include it within the PCDB.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.
Data held in the SAP Appendix Q database cannot currently be used in RdSAP assessments, which is a simplified version of the SAP assessment developed for assessing existing dwellings. Product performance data held in the SAP Appendix Q database will generally migrate to the PCDB when a new version of SAP/RdSAP is released, enabling RdSAP assessors to access this data.
Below are spreadsheets for various technologies recognised within SAP 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.
(1) ‘SAP’, ‘RdSAP’ and ‘Appendix Q’ are not approval schemes; no approval or endorsement is implied. If a product is recognised by SAP, either in the Product Characteristics Database (PCDB) or Appendix Q, it does not mean that equivalent or better results could not be obtained with alternative products or dwelling designs.
(2) BRE and DECC do not warrant the accuracy of data held within this website, or the Product Characteristics Database (PCDB) or Appendix Q database, where it is derived from data supplied by manufacturers or test laboratories.
(3) BRE and DECC do not accept any responsibility for fitness for purpose, safety, or any regulatory requirements applicable to products listed on this website, or in the Product Characteristics Database (PCDB), or in the Appendix Q database. BRE and DECC do not accept any responsibility for the installation of any of the products listed.
(4) Small differences in the calculated SAP annual efficiency values, SAP Seasonal Performance Factors or any other performance data held within the PCDB or Appendix Q database will generally be within the test uncertainty range and are therefore not significant and should not be relied on when comparing products.
