Implementation of energy efficiency measures
The first buildings on the campus opened in 1907, including a steam plant, at the forefront of modernity at the time. “Over the years, the system had become increasingly inefficient. First, new buildings were built on the campus, farther from the plant, and this distance led to losses in energy. Later, some parts of the network had reached the end of their useful life, especially the tunnels, whose critical condition threatened the integrity of the steam distribution system,” says Jérôme Conraud, Energy Manager, Installations and Ancillary Services at McGill University.
Rather than simply modernize the heating, the university completely renovated all the buildings, based on in-depth audits. The steam was replaced by a low-temperature warm water network that needs less energy. Production was relocated near the users to reduce losses, and a new thermal power plant and a satellite boiler room were built.
Various consumption-reduction measures were implemented. For example, a variable air volume ventilation system now adapts the heating to the actual occupancy of each room. Heat recovery systems were installed on the appliances that generated the most heat. And controls were mostly computerized, to the great pleasure of employees.
