Project: Air Tightness Testing – Mutton Lane, Potters Bar, London
Technicians: Cameron Milne & Mikey Crampton
4 Air Tightness Tests were required on a block of 4 Residential New Build flats for Nova Acoustics Ltd. We needed to measure and help increase the energy efficiency of the properties to determine whether they complied with the building regulations. Our focus was to pass the 4 flats to comply with Air Tightness Standard – ADLA1 – 2013. There was no target acquired from the client so it was assumed the target would be 5.
After being instructed to undertake this project, the first step of this process was to carry out a design concept review in order to determine any flaws in the design drawings. Issues were highlighted on the property as spot lights became a small problem with leakage however, it did not have a great effect on the overall scores. A thorough look around the property was required to make sure nothing would enable the property to fail. It is also a requirement to tape up all design ventilation so a fail would not have to be issued.
An On Completion Air Tightness Test was conducted and the 4 New Build flats all passed with scores:
The client will receive their pass certificate and be able to move on with their property.
