Pie Consults City of Fort Collins on New Air Tightness Code

Arvada, Colorado (March 29, 2012) – Pie Consulting & Engineering (Pie) recently consulted for and assisted the City of Fort Collins in assimilating a new whole building air tightness code requirement for commercial building envelopes into the local design and construction community.

Approximately one year ago on March 22, 2011, the City of Fort Collins adopted Ordinance No. 031, 2011 amending Chapter 5, Article II, Division 2 of the Code of the City of Fort Collins for the purpose of amending the 2009 International Energy Conservation Code (Ordinance).  Effective as of January 1, 2012, the ordinance now requires that all new commercial buildings, additions, and those undergoing major renovations shall be tested and have an air leakage rate that does not exceed 0.25 CFM/SF @ 75Pa of the total building envelope area when tested in accordance with the City of Fort Collins Air Leakage Test Protocol for Non-Residential Building Enclosures.

  • Assistance in the development of the City of Fort Collins Air Leakage Test Protocol
  • Consultation on testing agency qualifications development
  • Development of 8-hour training program for City personnel as well as local architects, engineers, contractors and sub-contractors.
