Green roofs have been widely used in Europe proved to be beneficial. However, in the US they are not
widespread. Previous studies have concluded that the main obstacle that makes architects, developers, etc. reluctant
to introduce vegetative roofs is their preference for the traditional roofing since it is a tried-and-true technology. A
positive feedback on the performance of vegetative roofs will encourage developers and possibly government
authorities to invest more in them. Therefore, a survey was conducted to determine the performance of green roofs
in existing buildings in hot and humid climates. This paper presents the results of this survey of around 40 buildings.
The methodology and pertinent questions are also presented.
Due to the many parameters involved in determining the rate of energy consumption in a building, a definite
conclusion regarding how much exactly they can effect on saving can not be drawn, however, the results showed
that green roofs can result in saving in the annual energy consumption and using shrubs as well as increasing soil
thickness were found to be most effective in reducing building energy consumption.
