What are the requirements of Jiangsu green building evaluation standards for indoor environmental quality of public buildings?

In order to implement the economic policy of saving resources and protecting the environment, promote sustainable development, standardize the evaluation of green buildings in Jiangsu Province, and formulate the evaluation standards of green buildings in Jiangsu Province. It is suitable for evaluating newly built, rebuilt and expanded residential buildings and public buildings (office buildings, shopping malls and hotel buildings) in Jiangsu Province. Among them, what are the requirements of Jiangsu Province's green building evaluation standards for the indoor environmental quality of public buildings? The following is a detailed introduction to the requirements of Jiangsu Province's green building evaluation standards for indoor environmental quality of public buildings brought by the construction network for reference.

Ⅰ control term
