Nine buildings that demonstrate sustainable building from across the country were recognized at the Canada Green Building Council (CaGBC) 2016 Canada Green Building Awards on June 6. the event, which was held at the Fairmont Royal York hotel in Toronto, ON, was hosted by Don Griffith, publisher of SAB Magazine and the CaGBC awards manager.
The winning structures were selected by four jurors.
The Ontario Regional winner and Technical Award winner was presented to the Bill Fisch Forest Stewardship and Education Centre. The centre is located in Whitchurch-Stouffville, ON. DIALOG Ontario Inc. is the architect for the structure, which features a high performance envelope with R-40 walls and an R-60 roof; a window-to-wall ratio of less than 30 per cent; and triple glazed windows oriented for optimal solar orientation. It is also net zero.
The Groupe Dynamite Atrium in Montreal, QC, is the Quebec Regional winner. The structure features a glazed atrium space, which makes use of natural light. The glazing helps to prevent overheating in the summer months and reduces heat loss in the winter. The high volume building encourages the stack effect and natural ventilation can be supplemented by mechanical means through two ducts. The architect for this project is Aedifica.
NSDA Architects designed the Budzey Building, which is located in Vancouver, BC. This building is a National winner. “This public sector project is a model for energy-efficient high-rise residential design. The 30 per cent window-to-wall ratio, the high performance envelope and heat recovery ventilation in each suite are strategies all private sector developers should try to emulate,” said the jurors.
Another National winner is the Jasper Place Library, designed by HCMA Architecture + Design and DUB Architects. Located in Edmonton, AB, it has achieved LEED Gold certification. The design incorporates innovative HVAC design to conserve energy and reduce heating demand. Ventilation air enters the building through a raised floor, and exhaust air travels through return grilles located at ceiling level.
Another national winner, Our House located in Toronto, ON, is a renovation of an 84 square metre home in the Roncesvalles neighbourhood. The house features a green roof over the front porch, two air changes per hour at 50 Pa, and a small ERV and boiler for efficiency. Solares Architecture Inc. is the architect for the project, and Our House is a national winner.
The Grange Triple Double, also located in Toronto, ON, is another residential national winner. The jury called the building a “flexible, multi-unit, multi-generational home.” The house allows for passive cooling and ventilation, and features an increased level of insulation at the brick façade. The high efficiency heating system has a 94 per cent AFUE natural gas forced air furnace coupled with an HRV. The architect for the project is Williamson Chong.
The SkyGarden House is a renewal of a century old single-family home in Toronto, ON, which transformed a small home into a three-storey, high efficiency house. It features natural ventilation, passive cooling, in-floor radiant heating, high-velocity cooling, low-flow plumbing fixtures and high-efficiency lighting. The architect is Dubbeldam Architecture + Design, and it is another national winner.
The British Columbia Regional winner is the Fort St. John Passive House located in Fort St. John, BC. Energy conservation for this house is achieved through the use of high performance triple pane wood windows, a wood structure with cellulose and mineral wool insulation and air-tight construction. The house features a heat recovery ventilation system, PV panels that generate power to run an air conditioner, and air source heat pumps with backup electric baseboards. The architect is Marken Projects.
The Atlantic Regional award was presented to the Dura House located in Terence Bay, NS. The house features fibreglass frame windows that have been placed and sized for solar heating, natural lighting, as well as ventilation. A heat recovery ventilator operates at 75 per cent efficiency and helps to drive ventilation. The architect is DR Coole Architecture Inc.
The awards ceremony kicked off a two-day CaGBC tradeshow event, which attracted 1000 guests. An opening plenary featured presentations from Premier Kathleen Wynne, Hon. Glen Murray, Ontario minister of the environment and climate change, Terry Homma, director general for public services and procurement Canada, and Vancouver city councillor, Andrea Reimer.
