What is the target for air tightness testing?

When it comes to the target for you air tightness test, you may hear a few figures being used and its important to understand the correct target your development is required to meet. Building Regulations Part L stipulates that the maximum air permeability rate that is to be achieved for any new build development is 10m3.hr.m2. However the likelihood is that if your development achieves a rating of 10 this will not achieve compliance with your SAP Calculations or SBEM Calculations. Therefore get in contact with your energy assessor to get the exact target for your development.

How much does an air tightness test cost?

Air tightness testing cost can vary per development as the size and complexity of the development determine the type of air tightness testing required. as a rough guide a single simple dwelling can cost a couple of hundred pounds, whereas a complex commercial development could cost much more. Similarly if your development has multiple dwellings discounts can be applied.

Do I need to carry out air tightness tests on all the units in my development?

It is possible to carry out ‘sample’ testing on your development if you have a number of units of identical design, however a 2m3.hr.m2 penalty will be applied to each dwelling that is not tested, therefore it is important to check with your energy assessor that this is acceptable before having the air tightness testing carried out.
