Séminaire du Sacré-Cœur, located in the Pointe-au-Chêne area of Grenville-sur-la-Rouge, is a co-educational private secondary school, recognized for its exceptional setting overlooking the Ottawa River. The institution serves approximately 480 students in facilities spanning over 8,300 m².
Challenges and objectives
Séminaire du Sacré-Cœur occupies a school building dating from the 1950s, expanded over the decades and now housing teaching spaces, sports areas and common services. The institution was still operating with aging mechanical equipment, including an oil-fired boiler used for space heating and domestic hot water, ventilation units without centralized control and a lighting network consisting primarily of T8/T12 fluorescent tubes and incandescent bulbs.
Several installations showed signs of end-of-life, manual operation and significant inefficiencies, both in terms of energy performance and indoor comfort. The absence of automatic regulation created temperature variations, inadequate ventilation and burdensome operation for technical staff.
In this context, the Seminary sought to modernize its infrastructure, reduce its dependence on oil, optimize its energy consumption and upgrade its systems in a coherent and sustainable manner, while improving comfort for students and staff.
Our solution
To address the identified challenges, we proposed a complete and integrated modernization of the Seminary’s mechanical and electrical systems. The solution aims to replace end-of-life equipment with high-performance technologies, while restructuring the building’s entire energy operation. At the heart of the project, the oil-fired boiler is replaced with a high-efficiency propane gas boiler, enabling the unification of heating and domestic hot water production in a single, more reliable and simpler-to-operate system.
This new energy architecture is supported by the addition of centralized control, capable of automatically managing temperatures, schedules, heated zones and air flows, thereby eliminating the numerous manual operations that made operation burdensome and inefficient.
Simultaneously, all interior and exterior lighting is converted to LED technology, significantly reducing electrical consumption, while improving lighting quality.
All of these interventions transform a building that was once energy-intensive and difficult to operate into a modernized school infrastructure, better controlled and oriented toward sustainable performance.
Significant Reduction in Operating Costs
The modernization of heating, conversion to propane and LED lighting transition enable a significant decrease in energy expenses, while reducing dependence on aging and energy-intensive equipment.
Improved Comfort and Air Quality
Through centralized control and new, higher-performance equipment, temperature is more stable, fresh air better managed and spaces better lit, improving comfort for students and staff.
Simplified operation and fewer manual interventions
Heating and ventilation systems, previously operated manually, are now automated, greatly facilitating the work of technical staff and reducing the risk of error or oversight.
Sustainable Modernization of Mechanical Assets
Replacing boilers, unifying networks and commissioning new controls extends the lifespan of installations, reduces the risk of breakdowns and supports a greener energy transition.
