China 14th Five Tender

The Ministry of Housing and Urban-Rural Development issued the 14th Five-Year Plan for the development of science and technology for housing and urban-rural construction. Goal By 2025 the technological innovation capability of housing and urban and rural construction will be greatly improved the technological innovation system will be further improved and the supporting and driving role of science and technology in promoting the green development of urban and rural construction achieving carbon peaking goals and tasks and the transformation and upgrading of the construction industry will be significantly enhanced. Research on regional building energy efficiency improvement technology based on accurate prediction of building user load and multi-energy complementation and develop efficient and intelligentPhotovoltaic buildingIntegrated utilization construction of a new type of building power system with light storage direct flexibility building-city-grid energy interaction technology research and application and development of urban wind power geothermal low-grade waste heat and other clean energy building efficient utilization technologies.The plan proposes that by 2025 prefabricated buildings will account for 30 of new urban buildings that year the installed capacity of solar photovoltaics in new buildings nationwide will exceed 50 million kilowatts and the application area of geothermal energy will exceed 100 million square meters.The policy is focused and optoelectronic building materials welcome development opportunitiesWith the goal of supporting green development of urban and rural construction and carbon neutralization it focuses on key areas such as energy system optimization low-carbon operation of municipal infrastructure zero-carbon buildings and zero-carbon communities and urban ecological space to increase sinks and reduce carbon. Strengthen the research and development of green and low-carbon technologies at different scales and levels such as county towns villages communities and buildings and form a green low-carbon and circular urban and rural development mode and construction model.Box 1 Key tasks of green and low-carbon technologies in urban and rural construction1.
