BSRIA provides a cost-effective ventilation testing service which can be conducted alongside our airtightness and sound insultation testing for minimal site disruption. We provide:
- nationwide coverage with regionally based engineers
- fully accredited engineers to provide certification recognised by Building Control
- rapid response and immediate results
The tests must be undertaken using UKAS calibrated equipment and should be conducted by an engineer registered with a competent scheme with respect to 'domestic ventilation technologies'. Where the engineer undertaking the testing is not registered a 25% penalty will be applied within SAP. All BSRIA Compliance engineers have successfully completed the BPEC Domestic Ventilation course.
These tests are required not only for system 4 (Continuous mechanical balanced system with heat recovery), but also for system 1 (Background ventilators and intermittent extract fans) and system 3 (Continuous mechanical extract).
In order to ascertain the correct ventilation rates required BSRIA will need the following information:
- SAP calculation worksheets for each dwelling
- ventilation type
- floor plans and sections for each dwelling
- occupant schedule
BSRIA only uses methods as described in Domestic Ventilation Systems as this is the only way to cost effectively obtain accurate readings. Also see video below for explanation.
