The Research of Ecological and Economic Benefits for Green Roof

摘要

Green roofs are a passive cooling technique that stop incoming solar radiation from reaching the building structure below. Many studies have been conducted over the past 10 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. With review and summarized the description of its functional traits in our country, this paper discuss the necessity to carry out the research on the functional traits of green roofs, and gave some suggestions about how to do this. At last, we propose the estimate method for the cost of green roofs construction project and green roof's economic value and ecological benefit.
