What is SAP Appendix Q?

If you are in the process of building your own home you will have come across SAP Appendix Q, but what exactly is it?

Well in simple terms SAP appendix Q is the way in which information, which was not available when SAP was published, is accessible to energy performance assessors. It measures product performance and set boundaries in which only the most efficient products comply with.

What does it mean in terms of a heat recovery ventilation system?

Continuous mechanical ventilation products with or without heat recovery have to be independently tested by the BRE or an approved independent test house, in order to comply with SAP Appendix Q. Every product that does comply is featured on thesap-appendixq.org.uk website.

Look for the logo on our datasheets to see which of our products have been approved by SAP appendix Q.
