A green roof is an engineered surface usually above a building that slows down the flow of rainwater and reduces the risk of storm surges after intense rainfall. Whilst they have been used for many years in mainland Europe and Canada they are becoming more and more popular in many urban environments around the world due to increasingly large areas of hard/impermeable surfacing in towns and cities. However there are other benefits to having a green roof:
- increases biodiversity;
- saves energy by improving insulation and reducing the need to artificially cool a building in summer (and heat in winter);
- lengthens the life-span of the roof;
- reduces the Urban Heat Island Effect;
I would like to shamelessly promote the good work of the The Green Roof Centre who provided me with some excellent practical training on the concept of having a green roof.
I now have to think of way in which I can incorporate a small area of green roof - maybe i'll start with my bug box.
