Cutting-edge eco-friendly prefab tours Canada

Coming soon to green living shows in Yorkdale, Canada (June 5-15) and Toronto (September 25-26), the Canühome is an example of cutting-edge eco-friendly home design. The Canühome website explains:

The 850 sq.ft. exhibition contains a kitchen, living room, dining room, bathroom and bedroom.

The exhibit includes interpretive panels which highlight the features of the design for the public...

Why is this exhibition so helpful? Ecolectic sums it up:

Made largely of FSC certified plywood and other wood materials, the modular home is assembled with the aid of steel brackets. Being modular you can hook up as many or as few units as you like should your need for space grow or diminish. The engineering behind the design is quite ingenious. Its shape allows for convective and radiant heating, and they proudly announce that "air is a building material"!

And Toronto's Globe and Mail newspaper goes into further detail:

...canühome's most intriguing feature is its passive solar "double envelope." Air passing between the two exterior walls on the south side is heated via the dark metal panels of the outermost skin. This heated air travels up and is vented out of the top in summer but, in winter, continues around the other side and into the radiant floor, which keeps the house about 10 degrees [50F]....

Canühome's "breakthrough" was the invention of a new fastener called a "Porcupine." These attach to the wooden structural ribs, extend outward to create the air gap and terminate where the outermost metal panels clip on. Not only is this method much cheaper, it's flexible.

Treehugger likes the idea:

...the designers have used the latest CNC technology and a lot of other ideas that make it one of the more interesting test beds we have seen.
