High performance air barriers and low infiltration rates are essential for ensuring healthy, comfortable, durable and efficient buildings and enclosure systems. Take this intensive one-day workshop with members of a team that has done more large-building air tightness testing than anyone else in Ontario!

Air tightness testing of commercial and multi-residential buildings is required for low-carbon, near-zero energy building codes and volunteer efficiency building programs (ie, ENERGY STAR Multifamily, LEED), and many Provincial building codes will soon require air testing of large buildings prior to occupancy.
Benefits of Large building air testing:
 - Significant reduction in heating and cooling loads
 - Preservation of the building enclosure by limiting moisture transport through air leakage
 - Notable reduction in occupant comfort concerts (ie, fewer drafts and easier control of interior conditions).

What you will learn:

- Ontario Building code requirements
 - Future potential code and program air testing requirements
 - Air testing / blower door operation and testing protocol
Best practice air barrier details, scopes of work and contracts.

  • Builders
  • Contractors
  • Site supervisors
  • Foremen
  • Site service
  • Architects and designers (BCIN designates)
