Air Tightness Testing
Air leakage is a main contributor to a building’s energy efficiency; therefore Part L stipulates that an air test must be taken to ensure the air permeability rating meets the target U-value set out in SAP. The test must be undertaken once all elements of the building’s envelope are sealed, so to ease the compliance process and provide support from design to completion, this is also integrated into the FSAP bundle.
Greenworks is offering a Part L compliant air tightness testing and consultancy. All the testing, calculations and consultancy required for compliance with Building Regulations are done for you.
Achieve compliance comfortably and economically by engaging with Greenworks from the outset. At the design stage the air tightness experts will provide constructive commentary on the proposed construction details, and facilitate a pivotal influence over the eventual testing outcome.
The service includes:
A comprehensive review carried out by experienced air-tightness consultants who will study and comment on the relevant drawn details.
A simple but effective method of interrogating the air-tightness strategy and key drawn details in the presence of relevant members of project teams on-site.
Short training presentations aimed at both designers and construction staff, which can be invaluable in raising awareness among those most able to influence the eventual outcome.
An inspection, prior to the tests carried out by our consultants, scrutinises the ‘air barrier’ details throughout the building and record all observations to be conveyed in a detailed, illustrated report.
Post-test Leakage Diagnosis
As required if a building fails to achieve the target permeability rate upon testing, our technicians will generally employ localised, internal smoke testing methods to identify remedial works required. Findings are then conveyed in an illustrated report.
UKAS Accredited Air Tightness Tests
Sample Area of ‘Comfort’ Testing: A ‘dress rehearsal’ air test carried out on a representative area to establish how the whole building will perform and what the key leakage issues will be.
Final Acceptance Air Leakage Test: The final test includes all necessary building envelope calculations and is carried out using multi-point testing methods to ensue even pressure distribution. In large, complex buildings, this approach, along with the ability to depressurise the building, can be vitally important.
