One of the joys of pedaling through different countries is seeing the way other people live. I fell in love with these green roofed homes in Norway:
Not only are green roofs beautiful, they have many Eco-friendly advantages:
- Dramatically reduce heating and cooling costs
- Extend a roof’s lifespan
- Filter heavy metals out of rainwater
- Filter pollution and carbon dioxide from the air
- Reduce storm-water run-off
- Provide habitat for insects (we need more bees) and other wildlife
- Help to stabilize a house
- Blend into woodland/rural surroundings
- Lower urban air temperatures
The cons are that green roofs cost more to construct than non-green roofs.The biggest cost being the waterproofing membrane(s).
Cities around the world are jumping on the green roof bandwagon:
- Toronto is the first City in North America to have a bylaw to require green roofs on new development.Toronto also offers green roof incentives.
- Copenhagen requires new flat-roofed buildings to have green roofs.
- London’s Mayor Boris Johnson (whose hairdo rivals Donald Trump’s) proposes that all major new developments within London are required to have a green roof.
- The city of Basel in Switzerland has the highest area of green roofs per capita in the world.
- Many German cities provide subsidies to developers who use green roofs.
- British Columbia Institute of Technology (BCIT) in Vancouver offers courses in green roof technology.
Wouldn’t it be nice to see more green roofs in our communities?
