The air barrier is an important component of a building envelope system that can improve heating, ventilating and air conditioning (HVAC) system performance, increase occupant comfort, improve smoke and fire control, and perhaps most importantly, reduce energy consumption.
With more than 475 facilities tested to date, totaling over 29 million square feet of building envelope, Pie’s air barrier consulting and performance testing services include:
The air barrier is defined by the Air Barrier Association of America as an assembly to “control the unintended movement of air into and out of a building envelope.” By reducing the uncontrolled passage of air through the building envelope to almost negligible amounts, the air barrier lowers energy consumption by reducing the associated heating and cooling loads as well as allowing designers to reduce the size of the HVAC system.
Since 2008, Pie Consulting & Engineering has provided industry leadership in the advancement of air barrier performance. Pie was a primary technical consultant to the United States Army Corps of Engineers (USACE) in their development of the air tightness testing protocol, ensuring our clients that our large building testing methodology and equipment will conform to the requirements of their project (USACE Protocol, ASTM E 1827, ASTM E 779, ASTM C 1060, ASTM 1186 and ISO 678).
“Thank you for your contributions in technology innovation by introducing building air tightness and pressure testing to Army facilities worldwide. The US Army is the first major building owner in the U.S. to require continuous air barriers with a maximum leakage rate in their new and retrofit buildings. This requirement will improve occupant health, comfort and productivity in their new and retrofit buildings. Your efforts reflect a high level of competence, dedication, and professionalism and are a credit to yourself and the US Army. I thank you for a job well done!”
