Energy efficiency and geothermal energy

Project description

Improving energy efficiency and implementing measures such as closed loop geothermal energy with electric heat pump for the main building, and geothermal energy with gas heat pumps in the CHSLD (residential and long-term care centre). Energy is also recovered from the chilled water network to heat the ventilation systems’ hot conduits. The project was carried out in collaboration with Johnson Controls and was divided into three main phases:

  • Main building’s boiler room.
  • Ventilation and geothermal energy for the main building.
  • The CHSLD care centre.

Challenges and Solutions

  • Very existing buildings that posed important restrictions (location of exterior air inlets, reduced space in ceilings, and asbestos).
  • Project carried out in an existing building without interrupting operations.
  • Establishing measures to prevent the risk of infection in the occupied zones.
  • Meeting a very tight schedule and an unalterable delivery date, despite modifications and additions to the initial project.
  • Planning shutdown periods in order to minimize interruptions to user services.
