Abstract:
Green roof strategy is one of the sustainable practices that not only provides thermal comfort for occupants but also reduces energy consumption of buildings as well as add aesthetic values to the environment. Over the years, there has been substantial development in designing and constructing vegetated building envelop. Green roofs provide environmental benefits by protecting buildings against solar radiation and temperature fluctuations and by reducing building’s energy consumption by direct shading. As most of the existing building in Serbia was built before building regulations that require higher levels of insulation, it is older buildings that will benefit most from green roof retrofit. This article reviews the current literature and compares findings, based on type of the green roof and climate, to consider the potential building energy benefits of green roofs, and the acceptability of implementation on a wider scale in Serbia, on a basis of real economical application.
