Case Study: CHUM reduces energy use and carbon emissions with GDI Ainsworth's hospital energy retrofit

CHUM cuts energy consumption 43.5% with GDI Ainsworth

CHUM's Notre-Dame Hospital, a leading teaching hospital in Montreal, was challenged by an aging, costly energy infrastructure heavily reliant on carbon-intensive heavy fuel oil. The complexity of its eight interconnected buildings and the need to maintain continuous hospital operations made achieving its carbon reduction targets particularly difficult. GDI Ainsworth was engaged to perform a comprehensive energy audit and implement an integrated solution.

GDI Ainsworth modernized the thermal power plant, completely eliminating heavy fuel oil. Their solution included installing a closed-loop geothermal system, replacing thousands of lighting fixtures with LEDs, and converting systems to variable air volume. This resulted in a 43.5% reduction in energy consumption, an 80% reduction in GHG emissions (9,450 tons of CO2/year), and validated annual savings of $1,677,819.
