Services Provided

  • BETAC conducted a pre-retrofit airtightness test on June 30, 2016 and construction on the retrofit began in late 2016.
  • The post-retrofit airtightness testing will be carried out once the retrofit is completed.  This is anticipated to occur in 2017 or 2018.


  • BETAC will be using the results of this testing to further expand their growing data base on airtightness characteristics of large commercial-style buildings which began in 2013 with the testing of 26 buildings in Manitoba.
  • Manitoba Housing has expressed interest in collaborating with BETAC to further these research activities as they apply to their portfolio of buildings, located around the province.
