In 2014/15 the École Heritage Immersion School in St Pierre-Jolys, Manitoba, underwent a major building envelope upgrade including complete removal and replacement of the west and north exterior walls plus the courtyard area.

Services Provided

• As part of this work, BETAC conducted a pre-retrofit test on the building in 2013 to quantify its air leakage characteristics and to identify significant air leakage sources on the building envelope.
• Following the retrofit, a second test was performed in 2016, allowing the impact of the test to be assessed.

Results

• The retrofit was able to reduce the measured air leakage of the building by over one-third, depending on the metric.
• The Equivalent Leakage Area (ELA₁₀) was reduced by 34%, or 0.39 m²(4.2 ft²).

The Public Schools Finance Board has expressed interest in collaborating with BETAC to further these research activities as they apply to schools around the province.
