To start the green building work comprehensively; to investigate the technology application, industrial development and work progress of green buildings in Chongqing; to clear and definite the development status of green buildings; to further clarify the development idea of green buildings in Chongqing; to put forward scientific and feasible development planning of green buildings in Chongqing; to promote the effective progress of green building work in Chongqing and to plan to launch development planning research of green buildings in Chongqing.

The national demonstration project of renewable energy building in Huazhong University of Science and Technology, approved by the Ministry of Finance and the Ministry of Housing and Urban-Rural Development, is achieved to build up a teaching or office building with renewable energy use to adjust temperature and comfortableness all year in Hot-summer & Cold winter area. There is used the Active Dynamic Air Envelope with air inter-layer. Fully use the advantage of underground temperature balance in a year and utilize renewable energy to adjust the flesh air temperature. The Underfloor Air Distribution System is including circle water with underground cool or hot source, underfloor radiator and flesh air vent. The used power of comfort adjusting system is equal or smaller than generated solar energy all year from photovoltaic cell on building roof. This project will store up solar hot in autumn and air cool in spring into underground for anti-reason use.

The project aims at quantifying the method of energy efficiency and CO2 emission reduction of cool roof in urban regional of China, and providing the theory and data support.

Large-scale application of river water source heat pumps in buildings.The research involves the research and analysis on river water resources (including Yangtze River, Jialing River, Wujiang River, etc.) in Chongqing, to make clear the quantity, quality and distribution characteristics of river water resources, analyze their availability and usable amount, provide suggestions on the appropriate zone, guarantee mechanism and incentive measures for the planning implementation based on geographical features, climatic environment, local resources, forms of building structures and other characteristics of Chongqing, and sequentially provide a guarantee for promoting the technology promotion and application of river water source heat pumps in Chongqing as well as improve the quality of energy utilization for air conditioning and reduce the energy consumption.
