Building Air Tightness & Facade Leakage Testing

As leaders in Building Air Tightness Testing, we offer advice, solutions and on-demand testing to deliver the results you need for your project.

Why is Building Air Tightness Important?

As Indoor Air Quality (IAQ) and energy efficiency of buildings becomes increasingly important, building standards and rating systems have been upgraded to regulate and drive improved air tightness in the construction sector.

In addition to the environmental and financial advantages of air tight and energy efficient buildings, minimising outside air infiltration will lead to improved IAQ by controlling moisture levels (to decrease mould and microbial risk) and a reduction in external particulates such as smoke and pollen. There many also be an additional payoff for an air tight building, due to the subsequent improved productivity outcomes.

Constructing non-permeable building envelopes becomes critical for technical and sensitive facilities such as research facilities, hospitals, and laboratories. In these environments, the introduction of unwanted outside air to the workspace via the building envelope can be detrimental to the research taking place or the health of patients and occupants.

Core Service

We can test your building envelope and facade to determine air permeability rates to achieve WELL or Green Star credits. Our certified people conduct testing to a number of standards including ATTMA TSL1 and TSL2, ISO 9972, ASTM E779, Passivhaus and ASHRAE requirements.

Furthermore, we employ a combination of techniques to determine air leakage points such as smoke testing and thermal imaging. 

Specialist Consulting and Expertise

In addition to the assessment of building air tightness or building envelope leakage (BEL), commonly known as blower door testing, CETEC also utilises similar methodologies to assess the air exchange effectiveness of occupied spaces.  This is an important tool for understanding occupant comfort, the development of methods to cope with “stale air” or “dead pockets", and is also becoming progressively more important for building accreditation schemes such as Green Star.

CETEC provides specialist consulting advice with respect to the permeability of building envelopes or the facade leakage and the advantages and disadvantages for the building and its occupants. As part of our service we are able to advise on the design of the building envelope to ensure that the detailed drawings identify a fully continuous air and vapour barrier that is the key element to create an airtight structure. 

We quantitatively assess the building envelope during construction. This has become increasingly important for verification of building techniques during construction, and assists with the awarding of Green Star credits (Design & As Built and Performance) for certification by the Green Building Council of Australia.

We also consult and provide a testing service for Duct Leakage and Facade-Section Leakage.
