Improve the Summer Comfort Environmental Benefits of Green Roofs

The summer (July to September) green roof, The empirical plane area set long 4250mm x width 3000mm x Height 200mm, planting trough set on rooftop, planting trough bottom-up sequence laying raised, waterproof layer, drainage layer, filter layer (non-woven, water the pottery stone), medium layer and vegetation layer, around the planting trough hollow brick interval income side in order to reduce the load.12:00-13:00 green roof planting area (upright type, stolons type) on the roof of a building roof areas isolated of solar radiation heat will also arrive the cooling effect, That better green roofs cooling (12.1807 degrees C) efficiency for upright type planting. The building room temperature difference is the dependent variable, relatively independent variables, test-below than in the control area cooling 13.7483 degrees C, green roofs roof than in the control area cooling 13.125 degrees C, control roofs roof than in the control area cooling 5.6714 degrees C, Test-below temperature cooling efficiency best. Green roof summer during the day at 12:00 period can indeed significantly reduce the building's roof floor surface temperature 11.81-13.53 degrees C, maximum temperature can even cooling up to 22.47 degrees C,and then adjust the indoor temperature of saving energy and reducing carbon effect; City building on the top floor facilities for green roof summer indeed can reduce with power 58.73%, achieve the energy saving effectiveness.
