Quebec City University Hospital Center (CHU de Québec)
Projects in healthcare environments require an exceptional level of organization and professionalism. At the Quebec City University Hospital Center, several factors made this challenge even more complex: the large size of the hospitals, an ambitious scope of work, and the presence of critical areas (operating rooms, trauma centers) meaning there was no room for error.
Ecosystem reengineered four of the center’s hospitals, which included boiler replacements, upgrades to the thermal plants, and reconfiguring numerous electromechanical systems. Efficient communication with the material resources team and precise procedures for project implementation ensured that the patients’ safety and comfort were maintained at all times.
Guaranteed Annual Savings
Implementing energy efficiency projects of this magnitude simultaneously in four hospitals was only possible in such a short timeframe with an integrated approach to project design and management.

Customized Performance Measures
The steam heating system—which was energy intensive and subject to leaks—was converted to a hot water system, which uses less energy to reach the required temperature. In one of the hospitals, the Laval University Hospital Center, over 1000 radiators were replaced on 6 floors. This was made possible in a live hospital environment through close collaboration with the client and meticulous construction management. The remaining steam systems in the hospitals, supplying equipment such as sterilizers, were optimized for improved energy efficiency.
Installation of a system that recovers heat generated by electromechanical equipment. This energy that would otherwise be lost is now redirected to the heating system.
Installation of a new geothermal heat pump that transfers heat from the ground to the building during the heating season, and rejects the building’s excess heat into the ground during the cooling season. For the three sites, more than 50 km of piping was installed in the ground.
Upgrade of Building Automation System in order to maintain occupant comfort and better manage energy consumption.
Upgrade of ventilation system to efficiently deliver warm and cool air where it is most needed, and maintain appropriate levels of fresh air.
Lighting: Replacement of older generation bulbs and fluorescent tubes by efficient luminaires providing better lighting quality.
Installation of solar thermal collectors that capture free energy from the sun and use it to pre-heat air entering the building.Share
