The Greening Of Toronto’s Roofs
image

Now that Toronto is sliding precipitously towards hotter days year round, we all might want to consider ways to reduce our energy consumption. It turns out that one great way of doing that is with green roof technology. Simply put, a green roof is a living membrane that absorbs light and heat from the sun and converts that energy into living plants. This living layer of insulation helps keep buildings cool resulting in lower air-conditioning costs.

Paradoxically to a North-American reader, auto manufacturer Toyota (you know, the one that makes the hybrid Prius and is about to become the world's biggest car manufacturer because it builds cars people want) is leading the market in green roof technology. Can you imagine Hummer-maker GM doing this?

Inhabit.com has more on Toyota's remarkable technology:
But the folks from Toyota Roof Gardens (a subsidiary of the Prius-creating car company) have solved your green roof installation qualms with a tile-based system that’s as easy as laying down carpet. The TM9 self-watering turf tiles measure twenty inches square, and connect directly to irrigation systems, making them entirely self-watering. And at a slim 2 inches thick, the tiles lightweight and do not require any additional structural upgrading to your existing roof.

At only $43 per tile, the TM9 system provides a modular, easy-to-install, cost-effective option for green-minded homeowners. In terms of maintenance, the tiles need only be cut once a year, thanks to a special breed of Korean velvet grass. And of course, like all green roofs, you’ll rest easy knowing that your easy installation is providing a natural cooling effect, thermal insulation, and a little extra flora in your home environment.
