In no cities (regional) areas with insufficient central heating or heating capacity are encouraged to use renewable energy such as air source, solar energy and ground energy for heating.

Follow the principle of adjusting measures to local conditions, give full consideration to building types and use functions, encourage and guide qualified reconstruction and expansion buildings in old residential areas to carry out green transformation according to green technology standards in the reconstruction of old residential areas, the improvement of urban appearance and rural revitalization projects, and actively promote the construction of new agricultural houses according to green buildings in villages and towns Standard construction.

（2） Comprehensively improve the proportion of precast and passive ultra-low energy consumption buildings.

For the construction of commercial housing community, the proportion of precast buildings shall be increased by no less than 5% every year on the basis of 20% in 2020; By 2025, the proportion of construction in the central urban area will reach 40%, that in other counties and districts will reach 30%, and that in “Yanghe New Area” and key development areas such as development new areas and functional parks at all levels will reach 50%, making the precast construction method one of the main construction methods of new civil buildings.
