Abstract

With the rapid development of urbanization in China, ecological problems in cities are increasingly alarming. In order to test the ecological benefits of roof greening on reducing energy consumption, cooling, humidifying, and controlling rainwater runoff, this chapter takes a roof garden at the Fujian Agriculture and Forestry University as a case study. This work verifies the effects of cooling, humidification, and lower energy consumption achieved by roof greening. Also, rainwater in the roof garden was monitored to test the utility of the rainwater collection system. Humidifying and cooling were effected significantly in the roof garden, where the temperature dropped by 1.8–4 °C and relative humidity increased by 5–10%. There was also a significant indoor temperature drop after the roof was greened. Furthermore, roof greening can have a significant insulating effect and is able to reduce energy consumption effectively. The monitoring results show that the roof garden also plays a significant role in controlling rainwater runoff.
