Telus building in Toronto certified LEED Gold
TORONTO
One of Toronto’s newest Class A office towers, 25 York Street, recently received its LEED CS (Core & Shell) Gold from the Canada Green Building Council, joining its largest tenant, Telus, whose office space received LEED CI (Commercial Interiors) Gold this year.
“In an advanced commercial real estate market like Toronto, tenants looking for premier office space are demanding LEED certification from the base building and often pursue LEED certification for the fit-up of their space as well,” says Jon Douglas, project manager for Enermodal Engineering, LEED consultant, commissioning agent and building performance monitoring specialist on the project.
“25 York Street is a great example of how a building owner and tenant can work together to create a building that is not only architecturally appealing and includes all the conveniences of a modern office, but also proves its sustainability through third-party certification.”
The $250 million 25 York Street project was designed by Adamson Associates and is operated by Menkes Property Management Services Ltd.
Enermodal Engineering oversaw the post-construction services of commissioning and building performance monitoring to ensure the building performed up to the LEED energy predictions.
As a result, the building achieved a metered 46-per cent energy cost savings compared with a conventional office.
In terms of actual energy use, the building uses 211 ekWh/m2 (equivalent kilowatt hours per square metre) compared with the Canadian commercial building average of about 400 ekWh/m2.
Enermodal said the building includes a number of green features. These include combination green roof and white reflective roof components, rainwater cistern for irrigation and toilet flushing and occupant-controlled ventilation diffusers.
Other features are occupancy and daylighting sensors, energy-efficient lighting design with individual fixture controls and dimmable ballasts, and low-emitting sealants, adhesives, paints, coatings, laminates, composites and carpet.
More than three-quarters of wood is Forest Stewardship Council certified.
Menkes Property Management Services Ltd. is currently working with Enermodal in pursuing LEED EB: O&M (Existing Buildings: Operations & Maintenance) certification for 25 York Street.
