A brief description of energy use standards and controls employed by the institution:

As part of its Sustainable Development Plan 2018-2022, the Université de Sherbrooke has implemented actions to update its energy efficiency standards, particularly for construction projects. The university's standards aim to surpass the 2015 National Energy Code of Canada for Buildings. In addition, the University systematically integrates renewable energy sources and/or specific energy efficiency measures into its construction and renovation standards for any project exceeding CAD 2,000,000 by allocating a certain amount of the budget provided for in the University's Real Estate Master Plan.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

The geothermal installations were built using techniques employed by the Université de Sherbrooke to improve the energy efficiency of its buildings. The University also has a Solar Park resulting from a research project.

1-Solar Park

As part of a construction-research project, the University has a solar park and photovoltaic panels located in various places on the Main Campus and at the Parc innovation-ACELP. The Solar Park of the Université de Sherbrooke has a capacity of 1 MW and is the largest dedicated to applied research in Canada. At the heart of the Main Campus, an intelligent solar thermal plant has been installed, while an experimental plant with thermal storage is located at the Parc Innovation-ACELP. Solar panels have been installed on the roof of the Yvon Lamarche Sports Centre. The Innovation Park-ACELP is also equipped with 23 solar trackers, as well as 2 trackers located in the traffic circles of the Innovation Park-ACELP and the Main Campus. A solar thermal panel was also installed on the roof of the power plant to preheat the water for the boilers.

As a true technological demonstration site, the Université de Sherbrooke Solar Park reproduces the reality of isolated networks and connected microgrids. It can be used to test different configurations: energy storage, transmission to the grid, and battery mode. It features five cutting-edge solar technologies: Monocrystalline, Polycrystalline, CPV, Bifacial, and Solar Thermal.

2-Geothermal Facilities

The Université de Sherbrooke Geothermal Facilities are deployed on four sites: the Longueuil Campus, the Life Sciences Pavilion on the Main Campus, the School of Music on the Main Campus, and the Gymnasium on the Health Campus. A project to deploy a geothermal plant is underway for the Health Campus.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:

From 2002-2003 to 2020-2021, the University enjoyed a period of growth in both surface area and student numbers. The Université de Sherbrooke has taken advantage of this opportunity to deploy an ambitious energy efficiency program on its campuses aiming to reduce energy consumption while also reducing the associated GHG emissions.

Between 2002-2003 and 2020-2021, some 45-energy efficiency projects or measures were carried out on the three campuses, representing investments of some $21 million. These projects include the installation of heat recovery and optimization systems such as heat pumps, heat wheels, heat pipes, runarounds, equipment replacement (higher efficiency boilers, windows, energy-efficient lighting), control optimization and recommissioning of mechanical systems, conversion of boilers to hydro, and geothermal systems. Some examples of the projects that have been implemented are:

• The installation of a heat pump in the Office of the President and the Central Library Building, and in the Georges Cabana Building on the Main Campus
• The installation of a geothermal system at the School of Music and complete replacement of steam heating with hydroelectric heating
• The complete renovation of the Student Life Pavilion (E1)
• The addition of an electric boiler to Pavilion Z5, on the Health Campus
• The modernization of the heating system in the student residences on the main campus (G1 to G15)

Construction and major renovation projects also include high-performance energy efficiency measures. Since 2002-2003, all of these measures have reduced the energy consumption of the Université de Sherbrooke's buildings by 44.4%. Overall, it can be observed that the reduction in energy consumption has been achieved by making optimal use of hydroelectricity.

Together these projects explain the significant reduction in “Imported steam, hot water, and/or chilled water” and “Stationary fuels used on-site to generate electricity and/or thermal energy” between the performance year and the baseline year.
