10 Canadian companies that specialize in sustainable, eco-friendly architecture

Anyone who lives in Canada knows the natural environment plays a huge role in its citizens' lives. Hiking, camping, canoeing, skating and skiing are commonly enjoyed (as weather allows), and most Canadians take great pride in their country's natural wonders. Not coincidentally, the nation also tends to be a hub for environmentalists, so Canada has its fair share of "green" buildings. 

Several larger projects and initiatives have gained international attention, such as North America's first carbon-neutral hospital (Sechelt Hospital in B.C., below, by Farrow Partners in association with Perkins+Will) and another North American first: Toronto's Green Roof Bylaw, in effect since 2010. "The T-Dot" – as locals call the city – was recognized by the Annual Green Roof Industry Survey (2016) for installing the most green roof area of all North American cities (more than 600,000 square feet), followed by Chicago  in second place.

Naturally, many grassroots architectural companies in Canada are engaged in green-building practices, but many are best known locally and often their most innovative projects are outside major cities. The Canadian "cottage culture" spans from coast to coast – usually a small cabin or farmhouse near a lake, river or other natural feature; remote hunting retreats are also fairly common. Straw bale, passive solar and off-grid, self-sufficient buildings are becoming more popular especially in remote areas, where access to supplies and utilities is often extremely expensive or, simply, unavailable. These humble structures have evolved into "second homes" often used as a country residence primarily during summer weekends, but with rising housing costs in Canada's major cities, many families are moving to rural properties that enable a less expensive, and more eco-friendly, lifestyle. With digital communication and remote offices, this often means commuting into the city (and the accompanying "carbon footprint") can be kept to a minimum.

In many cases these successful sustainable building projects have encouraged similar efforts in urban areas, either renovations to optimize energy efficiency or full-scale developments that achieve LEED Platinum and/or Passive House ratings. The resulting structures may not appear on the cover of magazines, but their appeal can be seen immediately in their low energy bills and low-impact building methods.

These 10 Canadian companies are at the forefront of sustainable construction and eco-friendly design:

After renovation, energy savings are estimated at close to 50 percent, with the installation of solar panels, LED lighting and energy recovery ventilators.
