Montreal’s Sun Life Building has received LEED Silver certification in the Existing Building: Operations and Maintenance category.
Built in three stages between 1914 and 1933, the historic 24-storey office building is located at 1155 Metcalfe St. on Dorchester Square in downtown Montreal.
The following changes were recently made:
- Upgrades to the HVAC systems by automating and centralizing the control system for all thermostats (1,650 units), lighting switches and building accesses
- Electronic filters installed throughout the fresh air supply system
- Cooling units replaced
- Six cooling towers renovated
- Ongoing maintenance and replacement of heat pumps
- Lighting for the parking area with a view to improving energy efficiency
- Water-efficient sanitary devices installed
- Installing water meters – a first for a commercial building operating in downtown Montreal.
“Bringing the building into compliance with today’s standards while taking into consideration the many constraints presented by the heritage status of the structure calls for architectural sensitivity and infallible attention to detail in terms of eco-responsible operations and maintenance,” said Mario Bédard, senior vice-president for Quebec and the Maritimes at Bentall Kennedy, one of North America’s largest real estate investment advisors.
In the late 1980s, the building underwent its first major renovation, involving the replacement of its 1,600 exterior windows, the modernization of its mechanical and electrical systems and a thorough cleaning of the façade. In addition, all of the office floors were renovated.
More recently, the building was equipped with modern infrastructure to meet stringent environmental standards, and with technologically advanced telecommunications facilities.
