Air Leakage Testing the Evergreen Brickworks

At the behest of Ryerson University’s Graduate Building Science Program, we were approached by master’s student Thomas Moore to test the new Evergreen Brickworks.

The Centre for Green Cities and the Younge Welcome Centre form one building that is LEED Platinum rated.  The vintage 1950 parts include the multi-wythe brick structure The Young Welcome Centre, some program rooms and a commercial kitchen. The addition to the main floor is at the back, the BMO Atrium and the upper floors for meeting and office space. We tested the two sections of building all together as part of this study.

Using industry standard metrics to estimate expected leakage, we set up 8 fans – moving 4900 cfm each – praying the building science gods would not fail us. Thankfully, we only needed 7 fans to depressurise and pressurise the building. Results will be published with Thomas’ thesis so stay posted!

Two fans were set up on in Meeting Room 1.

P1030355 (Large)

Three fans were set up on the ground floor.

P1030352 (Large)

We set up the control centre and 3 fans in the door way of Meeting Room 2. We were projecting the results live from TECLOG on the screen with one computer collecting data from each fan and manometer while also controlling the fan speed. Results were good with an R square of 1.000 for each the pressurisation and depressurisation tests.
