Simulated Study On The Potential Of Building Energy Saving Using The Green Roof

With the expansion of the scale of urbanization, a large amount of energy consumption and human activities seriously affected the outdoor thermal environment and air quality. The study of green roof has been greatly taken into account by reducing the building energy consumption. This paper mainly introduces the influence of green roof on exterior surface temperature taking a residential area in Jinan as an example. This study analyzes the heat transfer model of a building, uses the PHOENICS software to establish 3D building model and simulates thermal environment under the different green conditions. The results show the differences of building surfaces temperature under the different conditions of green roof. It proves that green roof can reduce building energy consumption. It provides a theoretical basis for energy-saving design in hot-summer and cold-winter zone. (c) 2017 The Authors. Published by Elsevier Ltd.
