Performance of green roof against the global warming

Abstract

In the past few decades, scientists are seeking to overcome issues; occurring due to global warming, which has reached into an alarming level. Global warming has led to many environmental issues including rising sea level and increasing indoor thermal discomfort. These sudden changes badly affect the occupants; living in the tropical climate condition which leads to enhance the heat discomfort in the buildings. As a result, researchers are forced to move towards the concept of sustainable building development for achieving better indoor thermal comfort. As a reason, the green roofs are accepted as a better alternative for overcoming impacts of global warming. However, the performance of the green roofs in a tropical climate is not addressed in Sri Lanka under the effects of global warming. This study emphasized on experimental approach of the green roof and its performance was measured by using small scale models. Using these results, large scale buildings were developed to simulate the performance of green roof under the effects of global warming. It was discovered that green roof provides an acceptable indoor thermal performance for global warming analysis than traditional roof types in Sri Lanka and green roof can be proposed as an ideal solution for achieving better indoor thermal comfort against the global warming effects.
