Green Roofs
An even better alternative to cool roofs (albeit one that requires more time and effort) is to turn waste roofs into landscaped
Green Roofs. Green roofs having the same cooling effect of white roofs, with the added benefits of:
◆Providing amenity space for building
◆replacing a yard or patio
◆Increasing roof life span
◆Reducing storm water run off
◆Providing noise insulation
◆Filtering pollutants and CO2 out of the air
◆Providing locally grown food (with roof-top vegetable gardens)
◆Increasing wildlife habitat in built up areas
◆Reducing heating (by adding mass and thermal resistance value) and cooling (by evaporative cooling) loads on a building
◆Reducing the urban heat island effect
越查资料,发现Grass roof的好处越多,甚至让人有点激动,是肯定要做了,有了些初步想法,但是,还要进一步计算。
