Reducing and preventing water waste
Date: August 2020
Details: In early 2019, the Unity Health Toronto Energy Team shared water data showing an abnormal increase in water use at Providence Healthcare. The Building Services team promptly took action; they investigated the entire facility and implemented effective correctional measures. Because of these efforts and the great work done by all of the teams involved, the water use at Providence decreased significantly in September 2019 to match previous years’ water consumption trends. See the graph above to see this trend.
- Prevented water waste per year: 14,800 m3
Providence LED Lighting Retrofit
Date: March 2020
Details: Providence had its first LED retrofit of 1,200 fluorescent lights in various corridors of the hospital. LEDs not only have a longer lifespan, but they also consume less energy while providing stronger lighting. This project is an important milestone towards sustainability at Providence.

New Chiller installed in the A-wing
Date: July 2018
Details: A new and highly efficient magnetic bearing chiller was installed to replace the existing A-Wing chiller. The new chiller uses less energy since it can operate without oil, which reduces the energy loss from friction and increases the heat transfer efficiency. The chiller provides cooling for the air handling units which provide 24/7 ventilation and cooling to all five floors in the A-Wing.
- Energy saved: approximately 65,000 kWh per year
- Incentive applied from SaveONenergy program, evaluation in progress
