OTTAWA — The Canada Green Building Council (CaGBC) has announced that a building at 100 Murray Street in Ottawa has been awarded Canada’s first Zero Carbon Building (ZCB) Performance certification.
The Bentall Kennedy-managed, Class A commercial office building located in the Byward Market achieved LEED Gold for Existing Buildings certification in 2016 and, through continued energy efficiency and carbon reduction measures, was able to demonstrate a balance of zero carbon emissions to achieve the new certification, a recent media statement said.
The building owner is Sun Life Assurance Company of Canada, Urban Equation is the sustainability consultant and Energy Profiles is the energy engineer.
Among the measures that contributed to the building’s zero carbon certification are its near total use of electricity as the primary energy source, the establishment of an advanced building automation system, and the use of efficient lighting and control systems throughout the property. Electricity from Ontario’s low-carbon grid accounts for 95 per cent of the building’s energy use.
The building performs better than 92 per cent of comparable structures, said the statement. In addition, Bentall Kennedy is nearing completion on a costed plan to replace equipment and phase out the remaining use of natural gas in the building.
ZCB-Performance certification requires buildings to demonstrate they did not generate any carbon emissions over a 12-month period of operations, with performance verified annually.
“This certification is representative of Bentall Kennedy’s commitment to delivering value for our clients while, through tenant partnership, achieving remarkable things from a sustainability standpoint,” said Anna Murray, vice-president, sustainability at Bentall Kennedy in the statement.
The CaGBC has also announced it has signed on as a new tenant at 100 Murray, with plans to relocate its Ottawa headquarters to the building in summer 2018.
“I would like to congratulate Bentall Kennedy on achieving Canada’s first ZCB-Performance certification and showing their commitment to zero carbon buildings. This project clearly demonstrates that LEED certified buildings are great candidates for a zero carbon retrofit, taking performance to the next level,” said Thomas Mueller, president and CEO of the CaGBC.
