Whole-Building Air Barrier Testing and Compliance

With up to 30% of your building’s energy usage to compensate for air leakage, the need to control the air entering and leaving your building is more than an air quality issue. It’s a building efficiency and cost issue. By making a building more airtight and incorporating a balanced ventilation strategy, less of the conditioned air is lost through the building enclosure, reducing the load on the mechanical systems. This not only puts less stress on ‌the mechanical systems but also allows for more efficiently sized equipment.

With Intertek’s “Whole Building Air Barrier Solutions”, building owners can be assured that their building enclosure is airtight, meeting required performance targets required by code and high-performance building standards.  This will all lead to obtaining optimal energy efficiency for the whole building.

Whole Building Airtightness Testing

Detailed airtightness testing is the foundation for understanding your building's performance. We conduct rigorous testing aligned with industry standards (ASTM, USACE, ISO) to precisely measure air leakage rates. This data helps you verify code compliance, target improvement efforts, and optimize the sizing and operation of mechanical systems for ultimate energy savings.

Air Leakage Identification and Resolutions

Hidden air leaks can be challenging to pinpoint. Intertek employs advanced techniques, including infrared thermography and diagnostic testing, to locate leaks accurately—even those concealed within the building structure. Additionally, our Building Science Solutions team provides proactive consulting during the design and construction phases, minimizing the risk of air barrier failures and costly repairs down the line.

Building Performance: Compliance and Energy Efficiency 

Navigating the complex world of air barrier codes and testing standards can be overwhelming. Intertek's experts guide you through the requirements, helping you design an air barrier system that matches your building's needs and performance targets.  We develop holistic strategies that prioritize energy optimization alongside other essential building health considerations.
