Accreditation in Heat Recovery Ventilation

As we started the process of developing our own heat recovery ventilation units in the 1990’s, our goal was to provide the market with the best solution possible. This ethos has not changed as we invest heavily in R&D and provide new and improved products to match the demand in this developing area.

The ProAir 300 & 600 heat recovery ventilation units were among the early listings on SAP (Standard Assessment Procedures) Appendix Q, when it was instigated back in 2006. The ProAir 600LI has supereceded the ProAir 600 unit and it is also listed on the SAP Appendix Q database.  This is the route through which product performance data is made available to SAP assessors.

In order to achieve a listing on Appendix Q, the product is tested by the Building Research Establishment (BRE) in the UK. This test is primarily an assessment of the energy efficiency of the unit, but is also rigorous in its treatment of other aspects of H.R.V.

It is also the means by which test and calculation methodologies can be agreed that can be used to measure product performance and when and how that performance can be treated in SAP. Both the heat exchanger efficiency and the motor efficiency (specific fan power – SFP) have been verified by tests carried out by the Building Research Establishment (BRE) in the UK. The results are posted in their online database which acts as Appendix Q of the SAP and DEAP systems. These tests have been done in accordance with the EN 13141-07 Standard which is rigorous in its treatment of other aspects of HRV as well as energy efficiency.
