ABSTRACT
Green roofs are a passive cooling technique that stops incoming solar radiation from reaching the building structure below. Many studies have been conducted over the past I0 years to consider the potential building energy benefits of green roofs and shown that they can offer benefits in winter heating reduction as well as summer cooling. Statistics have confirmed that a lawn placed on a roof top can reduce the cooling load. In this study, the eQUEST energy simulation program was used to determine the effects of roof gardens on the annual energy required for cooling, and annual electrical usage in a computer based model. In this case study two different cases were considered first one of only roof garden, later with 2inch XPS (Extended Polystyrene). It has been found that 3.79% of cooling load can be reduced by best case.
