AirEx smart air brick impact recognised in EPCs

Following the inclusion of Airex’s Floorvent system in SAP Appendix Q it is now possible to include the system in a home's EPC. The up to 12% reduction in heat loss that Airex Floorvent results in equates to a 2-5 SAP point increase for a home, depending on its characteristics.

AirEx Floorvent uses Airex’s unique smart air brick technology to regulate otherwise uncontrolled airflow beneath a suspended floor. The air bricks close to maximise thermal efficiency and open to ensure adequate airflow to assist with damp prevention. The system has been designed to be simply retrofitted into homes with existing sub-floor air bricks to improve their energy efficiency. The installation can be completed by a trained installer in around an hour. 

The Standard Assessment Procedure (SAP) is the method for assessing the energy and environmental performance of a home used to produce Energy Performance Certificates (EPCs). SAP Appendix Q is a mechanism for incorporating new technologies into SAP. The findings of the AirEx’s ECO3 Demonstration Action trial were used as the basis of Appendix Q inclusion with the BRE, Ofgem’s Technical Advisory Panel (TAP) and the SAP Scientific Integrity Group (SAPSIG) all validating the impact of the Airex Floorvent system.

Inclusion in SAP opens the door for the Airex Floorvent system to be installed through a range of energy supplier and government funded programmes. Having been recently approved for installation under the Scottish government's Warmer Homes Scotland programmes such as ECO4, LAD, HUG and SHDF offer the opportunity for more fuel poor households to benefit from the energy bill reduction Airex’s technologies can provide.

Agnes Czako, CEO & Co-Founder of Airex, said: “Recognition within SAP is a major milestone for Airex. This will enable our customers to quantify the impact our technology has in improving the thermal performance of their homes as well as helping them access funding and meet EPC targets”
