Air Tightness Green Star Points
Ask any ESD consultant to list the most important aspects of an energy efficient commercial building, and near the top of the list will be air tightness/build quality.
Implementing airtightness can be more cost-effective and longer lasting than installing
- Solar panels
- LED lighting
- even a high-efficiency mechanical system
One of the major reasons why a building may fall short of its energy efficiency goals is that it may be leakier than anyone had imagined. The best way to ensure a building actually ends up airtight is to test it.
Up until now, air tightness testing is actually one of the least awarded points for the Green Building Council of Australia’s Green Star program. We are hoping to change this. In the two years since the airtightness testing points were introduced, approximately 211 total Innovation Challenge points were awarded to 84 Green Star projects but only ONE point was for Building Air Tightness.
Air sealing introduces benefits for:
- energy use,
- environmental, and
- comfort benefits.
- lower maintenance
Buildings can get a Green Star point for just testing the airtightness of the building. If you achieve an airtight building, you can get additional points.
There are changes coming up for the Green star points associated with Air tightness/Blower door testing.
Common questions we love talking about…
- How much does an airtightness test cost?
- How much can a project save by air sealing?
- What’s a typical result for a project like mine?
- Should I use a blower door fan setup or should I pressurize the building envelope with the HVAC system instead?
Efficiency Matrix has “actual” experience in testing/remediating some of the largest commercial building for Airtightness in Australia. We have demonstrated assisting our customers to achieve some amazing results.
