The Canada Green Building Council has certified 270 Albert Street in Ottawa as its first existing commercial building to be certified under its LEED v4 for Building Operations and Maintenance: Existing Buildings (LEED O+M: Existing Buildings) rating system.

Located in downtown Ottawa, the 14-storey, multi-tenant building was constructed in 1975. Since then it has undergone several major retrofits and was already operating efficiently when an energy audit was conducted in 2013. WSP Canada were the LEED consultants for the building owner Blackwood Partners.

The recommendations of the 2013 audit were implemented within a year. They improved the building’s energy performance by a further 25%, resulting in an energy use intensity of 20ekWh/sf,  an Energy Star score of 91, and a LEED Gold Existing Building rating of Gold.

Mark Hutchinson of the CaGBC, says:  “Projects like 270 Albert set a strong example of leadership in action. They demonstrate how LEED v4 is providing project teams with a rigorous set of requirements and guidelines that, when successful, can lead a 40-year-old building to become a top-performer, saving energy and thereby reducing carbon and combating climate change.”

The CaGBC saw another big milestone in the third quarter of 2016. It surpassed 6,000 LEED registrations in Canada, for a total of 6,096. There were 70 new certifications between July 1 and September 30, with the cumulative total of LEED certified projects across the country at 2,854.

In addition to 270 Albert Street, other projects of note that earned LEED certification during the third quarter include:

  • The Halifax Central Library in Halifax, NS, certified LEED Gold.
  • Kwayatsut (at 2465 Fraser Street) in Vancouver, BC, certified LEED Gold.
  • 120 & 130 Adelaide West (Richmond-Adelaide Centre) in Toronto, certified LEED Gold for Existing Building.
