Air Barrier Performance Testing Report
Dear Mr. Stolte:
In accordance with our agreement for professional services, Pie Consulting & Engineering (Pie)
has conducted performance testing of the air barrier system for the Foothills Mall
Redevelopment Block 13A in Fort Collins. The purpose of this performance evaluation was to
provide Heath Construction a building air tightness performance value of the as -constructed air
barrier.
This report provides The City of Fort Collins Certification of Compliance, a summary of the air
barrier test procedure, and results of our performance testing. The purpose of the performance
testing was to quantify the amount of air leakage occurring through the air barrier test
envelope.
The testing was performed on June 5, 2015 by Scott Terry of Pie.
