Building Benefits
Energy savings
In hot climate, a green roof acts as a buffer that protects the building from extreme solar radiation, and hence reduce, the net heat gain Therefore it helps in cooling the surrounding area, as well as regulating the internal building temperature and decreasing the amount of energy required to cool the building. The implementation of a green roof reduces the requirements for traditional insulation.
Roof Membrane Protection and Life Extension
Green roofs help to protect roofing membranes from extreme temperature fluctuations, and reduce the negative impact of ultraviolet radiation, thus double the life span of a conventional roof, and decrease the need for re-roofing. These are direct operational cost savings for the building owner.
Sound Insulation
Green roofs can be used as acoustic barrier; with the plantation medium Ike soil blocking lower frequencies of sound, and the plants blocking the higher frequencies. Tests show that 12 cm of plantation medium alone can reduce sound by 40 db.
Additional Benefits
A Green Roof transforms an underutilized area into an opportunity to have an outdoor space with fresh air, or a gathering area. In highly urbanized areas, Green Roofs add aesthetic pleasure, and correspondingly - added property values. For example, accessible green roofs, which provide added amenity space for the occupants, can help to increase the unit value of condominiums, in addition to the increase of marketability to office or residential suites for buyers.
