Studies on the Heat-Resistance and Energy-Saving of the Eco-Roof in Southern Urban Districts

Roof is one of the main structures of a building, and it plays an important role in improving the degree of indoor thermal conformability so as to reduce the using of air-conditioner. Through a contrastive study on eco-roof and the common roof in a certain living district in Xiangtan City, the article comes to the conclusion: the water-storing green roof can enhance the urban eco-environment, modulate the indoor thermal property and decrease the using of air-conditioner.
