Green Roofs?
do they cool or heat a building? I totally don't understand about green roofing systems.
Yes they do cool buildings. Green Roofs/Oikosteges are a superior form of thermal insulation among many other things.
Green absorb solar radiation and in turn provide insulation. They help keep the heat out when the it is too hot and if it is too cold they keep the heat in. BTW, white absorbs less solar radiation than any other color.
I agree with both posters. It also prevents storm runoff and help miniminizes the urban island effect. The plants also perform other useful functions such as filtering pollution in addition to the insulating values.
Simply put it green roofing system saves money and cushions the environment from the impacts of man made structures.
i like the green roof ..it's good for our world..

Green roofs can be built using different materials,
A galvalume roof will reflect the suns beams away from the building keeping it cooler in the summer.
A cool white roof color will keep the building even cooler then the galvalume roof, it is the most reflective roof in the market.
Solar panels to supply the entire building with energy.
And the last step to having a green roof is some translucent panels/skylights they will save energy during they day.
All these options can get you a LEED certified roof.
Green roofs and indeed green walls have several purposes.
Primarily in most circumstances they provide a wildlife space, contribute to reducing carbon by turning it into oxygen.
Secondly protect the roof/wall from the effects of direct sunlight and wind/rain.
Thirdly it keeps the building cool in summer and warmer in winter, for example rain directly on walls increases the heat loss from the building so a plant acts as a barrier to the rain.
To get an idea search for green roof and green wall on your favourite image search engine so that you can see examples.
There is a french guy (forget his name) but he more or less made it commercially viable.
The most important point is that they look great, can't imagine anyone preferring to see brick or concrete
