3ARK is committed to improving the comfort and energy efficiency of Australia’s buildings. 
We do this by:
  • Advising on how to design and build airtight buildings – so that air infiltration is controlled rather than unplanned air-leakage which affects comfort, air-quality, and requires greater consumption of energy to maintain desired air temperature due to loss of conditioned air.
  • Performing a verification test of the building envelope performance. i.e. a quantifiable figure to measure against best practice.
  • When the air-leakage is greater than planned, we can identify air-leakage locations so that remedial action can be taken
  • Assessment of existing homes using the Victorian Residential Efficiency Scorecard which will enable you to obtain a star rating for your home which is an assessment of your home’s building shell and a representation of the running cost of the fixed appliances in your home. It will guide you to make home improvements efficiently and cost effectively.​

Although the Airtightness industry is very much in its infancy in Australia, 3ARK have worked with a variety of stakeholders including constructors, various industry groups, engineering firms and design teams, at various stages of the building life cycle, to air pressure test a diverse cross section of buildings in the commercial/private and government sectors.

We can also assist via:
  • Engagement as SME’s to advise teams on managing Airtight builds
  • Advice on Sealing methodology and correct use of specified sealing products
  • Provide budgetary pricing and estimates
  • Input to design scope by conducting baseline air- leakage testing and identification for Refurbishment/Retrofit projects
  • Collaboration on proposals
  • Demonstration of Airtightness testing to clients and project teams
  • Feedback on the practical impact of design to the building envelope and risk mitigation
  • Objective assessment of building envelope in client/builder dispute
