Air Tightness Study

Thank you for your interest in our Air Tightness Study.

The air tightness of your home affects how much energy is needed for heating and cooling. A less air tight or leaky home allows more conditioned air to escape and more external air in, which can raise your energy bill by up to 20 per cent.

Currently there is no minimum requirement for air tightness in newly built homes or apartments, so an assumed level is used in energy efficiency modelling for building code compliance.

This study will investigate how air tightness levels in newly built dwellings compare to these assumed values.

What does participation involve?

Your participation involves granting access to an accredited technician to perform an air tightness test on your home. This takes approximately one hour and requires all doors and windows to remain closed during the process.

There will no cost to the homeowner and a copy of the test report will be provided, which is normally $600.

Sounds interesting, what are the next steps?
