Study on Sponging Renewal Strategies for Older Neighborhoods in Changsha City
At present,China is in the key stage of ecological environment construction,and sponge construction can improve the water environment and thermal environment,improve thermal comfort,so as to reduce the construction energy consumption.The paper carries out a field survey on the sponge transformation status of 24 representative old neighborhoods in Changsha,classifies the old neighborhoods into three grades:poor,good,and excellent,and systematically analyzes the sponge background conditions of the old neighborhoods in each grade.With the goal of improving the outdoor water and thermal environments of old neighborhoods,and taking insufficient greenery,restricted space,and poor drainage as the entry point,using sponge measures such as rain gardens,planted roofs,rainwater ponds,and permeable paving,we formulate sponge renovation and renewal strategies for Changsha city's old neighborhoods at different levels to renew and optimize the environment of old neighborhoods,and to provide references for the construction of sponge renovation projects in the future.
