The Green Roof movement is gaining momentum in the city of Vancouver. More and more people are educating themselves when it comes to the environment and what they can do to help. Helping the environment helps us and not only in the ways we've been led to believe.
Why is a Green Roof greener? Aside from the obvious...
Lasts Longer: A green roof can last up to 3 times longer than a conventional roof. Possibly more. Because of this a green
roof will be less expensive and will result in less material in landfill.
Regulates Temperature: A green roof has amazing insulation properties helping to keep your home warmer in the winter and cooler in the summer. In a city environment it will help reduce the heat island effect.
Reduced Electromagnetic Radiation: New studies are showing that green roofs can almost eliminate electromagnetic radiation penetration.
Noise Reduction: The plants on a green roof block higher frequencies while the soil blocks lower frequencies. The result can be a total noise reduction inside a building of about 40 decibels. Great if you live by a freeway or an airport.
Storm Water Management: A green roof can absorb up to 60% of rainwater throughout the year and what little runoff there is will be delayed which reduces stress on city water systems.
Air Quality: Green roof plants have been proven to capture dust and other pollutants. They can also filter out harmful gases such as carbon dioxide and then release oxygen back into the air. Mmmmm, more oxygen.
Urban Agriculture: What a great place to grow veggetables! It's sunny and open and normally a space you wouldn't use.
Look Nice: Really? What more can we say? Population density is a wonderful thing for the environment. It keeps all the people in a smaller space so we damage less of the world. The bad part is that we are looking down on a lot of roofs. Wouldn't it be so much nicer to look down on green spaces that are constantly changing with the seasons?
Green roof plants are not your average run of the mill garden plants. The roof is a harsh environment with little moisture and a lot of sun so plants need to be chosen with care.
