Steam and noise at the downtown powerhouse due to boiler tests

As part of McGill’s efforts to reduce its greenhouse gas emissions, a natural gas boiler in our downtown powerhouse has been replaced by two electric boilers. Additionally, we have installed equipment that allows us to conduct annual boiler combustion tests. These tests might cause a large steam plume and high levels of noise. It is important to note that the tests will not pose any health or safety risk. The first test will take place on Saturday, October 28, in the morning from 9 a.m. to 1 p.m.

During these tests, we will temporarily increase steam demand beyond normal levels. This helps us simulate the impact of adding more buildings to our network, such as the New Vic, and ensure that our equipment can safely handle this increased demand. On October 28, a first test will be carried out to verify whether the installation’s muffler functions as it should.  

While the tests are conducted, you may observe a large plume of steam coming from the powerhouse (at the Ferrier Building, behind the Arts Building), and hear noise levels up to 120 decibels, which is comparable to the noise generated at a rock concert, and is likely to be heard across campus. Despite their imposing appearance, these elements are not a cause for concern. 

Depending on weather conditions, the steam plume may remain close to the ground and possibly impact visibility. Please be assured that our on-site teams will closely monitor conditions and postpone the tests if necessary. 

A second, similar, boiler combustion test will be conducted at some point in the following months.  

We regret any inconveniences this situation may cause. If you have questions or concerns, please contact your building director, who will connect with us.
