Presented by Dave Bohac P.E. | Director of Research

The energy required to heat and cool outdoor air and infiltration air is a significant fraction of thermal loads. This project has developed diagnostic procedures to identify air leaks and methods to calculate the savings from air sealing large commercial and institutional buildings. Envelope air sealing could significantly reduce large building energy consumption, but no systematic research has identified the most cost-effective strategies for Minnesota buildings.

Director of Research Dave Bohac presents research findings and the procedures used for conducting air leakage testing. The findings speak not only to potential cost-effective energy savings, but also to tools and programs that may be developed to help capture these energy savings.

Target Audience

  • Utility Program Managers and Auditors
  • Architects and Engineers
  • Commercial Contractors 

Webinar Outline

  • What was the range of envelope leakiness found during testing?
  • What impacts does this have on energy usage and utility costs? 
  • What are the effects of mechanical systems on building pressure and how might it affect design practice?
  • The degree to which air sealing can be a cost effective measure in a cold climate
  • Opportunities to incorporate air leakage testing into current commissioning and retro-commissioning activities
  • What tools might be developed to effectively communicate these findings to building professionals?
