Research on the Effect of Enclosure Greening on the Building Energy Saving

Two same concrete experimental models are made to simulate solid buildings with the control variable method, by making 100% coverage of roof greening and 50% coverage of wall greening on the enclosure of one model, and taking the other model as the reference without arrangement of greening. Then collect the data of the temperatures inside and outside the models. The analysis shows that during the period from October, 2010 to March, 2011, the average accumulated temperature of the test model is 1.31°C∙h higher than that of the control model, and the green plantations can effectively reduce the heat transfer coefficient of enclosure structure, and improve the thermal resistance of the enclosure. The greening method used in this experiment can improve the thermal insulation of the enclosure by about 10%.
