Customer success stories
Innovation is the name of the game for the
Université de Sherbrooke
 |
The Université de Sherbrooke, a Hydro-Sherbrooke customer, puts a high priority on sustainable development. It has carried out four projects under Hydro-Québec’s Building Initiatives Program – Major Customers. Energy-optimized buildings The university chose geothermal energy for its new life sciences complex. Under the Building Initiatives Program, it was able to complete two projects thanks to financial assistance from Hydro-Québec. The university also wanted to increase the energy efficiency of its existing buildings and two building optimization projects were also submitted for funding under the Building Initiatives Program. |
New building — Pavillon des Sciences de la vie
Project 1: Installation of a geothermal system with fourteen 160-m wells
The heat pump transfers the energy released by the ventilation exhaust systems to the heating and air-conditioning systems.
Existing buildings
Project 1: Transformation of a pair of two-duct, constant-flow ventilation systems into two variable-flow systems
Project 1: Installation of a geothermal system with fourteen 160-m wells
- Install a variable-speed drive (VSD) system on the ventilation system.
- Install a geothermal system for preheating and precooling.
The heat pump transfers the energy released by the ventilation exhaust systems to the heating and air-conditioning systems.
Existing buildings
Project 1: Transformation of a pair of two-duct, constant-flow ventilation systems into two variable-flow systems
- Install variable-speed drives on ventilator motors.
- Modify controls.
- Install variable-speed drives on main pumps.
- Convert three-way valves for coils into two-way valves.
- Eliminate secondary pumps.
- Replace several coils.

Conclusive results
The university’s energy efficiency projects not only resulted in substantial energy savings, but were also very cost-effective. With financial assistance of over $773,000 from Hydro-Québec, the payback period was cut in half.
