An Empirical Study of the Effects of Green Roof on the Outdoor and Indoor Thermal Environment of a College Buildings in Winter

With the continuous progress of urbanization, urban ecological problems have been widely concerned. The heat island effect produced in cities affects people's lives, and it is increasingly urgent to solve the problem of heat island. Roof greening is closely related to buildings. It is a new greening method, which has advantages in improving ecology, regulating climate and building energy conservation. The campus not only meets the greening needs of teachers and students for the environment, but also pays more and more attention to the energy-saving utilization of teaching buildings, college buildings and other buildings. In this context, campus roof greening came into being. In different seasons, roof greening will have a certain impact on the indoor and outdoor thermal environment of campus buildings. By means of on-site measurement, this paper scientifically and quantitatively explores its impact, and then analyzes the data to obtain experimental conclusions such as the insulation effect of the top floor indoor. It is hoped that this article can provide some reference for whether to use roof greening in buildings.
