AEI is now offering Building Air Infiltration / Exfiltration test services that have only before been offered to the largest of clients by Engineering and Design-Build firms. Interest in energy efficiency and building envelope performance has required more attention to detail and has driven the need for our services. Even though air barrier incorporation into new commercial buildings has not yet become the norm, new building codes are rapidly moving in this direction around the country. Air barrier incorporation into new commercial buildings can both increase the longevity and durability of the building envelope. We can work directly with building owners, building enclosure consulting firms, architectural or engineering firms who do not provide building performance testing. We provide third party assessment to those who need answers.

When air barrier and air sealing requirements are specified into the design details of commercial projects, they are assumed to be properly completed. The only way to know that a building has the targeted level of air tightness is to measure the air leakage.

We provide the following test services:


  • Air Barrier Inspection and Consultation
