Green roofs in detail. Green roofs (also called living roofs, brown roofs, eco roofs, sedum roofs, turfed roofs, grass roofs, vegetative roofs and biodiverse roofs!) are designed to provide a range of benefits that enhance the efficiency and ecological performance of the building.
As we become more aware of our impact on the environment, we begin to think about how we may make a positive difference. A green roof has beneficial effects on biodiversity, energy consumption, contributes towards mitigating climate change, and reduces Urban Heat Island Effect caused by human activity. A green roof also provides a habitat for various flora and fauna.
A rural green roof can be designed to blend with its surroundings, by using a planting scheme as close to the natural landscape as possible. A range of grasses may be used, or even a meadow-like carpet of colourful wild flowers. An urban roof may look good with a contemporary design of lawns and shrubs. And it’s not just about appearance – the carbon consumed by the plants during photosynthesis positively removes emissions, and the green roof can also capture gasses. Green roofs return moisture to the environment through evapotranspiration, reducing solar gain and improving air quality.
The green roof is a sophisticated modern structure: the finish is complimented by a waterproof membrane system. Felt, single ply membrane of liquid plastic can all be used depending upon the individual building’s needs. The result is an attractive, eco-friendly, waterproof and well-insulated roof, with positive benefits on the efficiency of the building and for the planet.
