This is a non-traditional greenhouse designed specifically for northern climates characterized by extensive summer sunlight and cool nights. These greenhouses are not all glass or plastic, but instead have an opaque northern wall made out of a material that will collect and radiate solar heat into the greenhouse throughout the cool nights, and a roof that actually provides some shade from the intense mid-day sun!
Check out this blog post from Verge Permaculture describing the design and construction of their backyard greenhouse in Calgary.
The Invermere Community Greenhouse (photos to the right!) is a stellar example of passive solar greenhouse design! Check out this You Tube video chronicle!
