The Housing and Urban-Rural Development Bureau of Shijiazhuang City indicated that the energy-saving design standard for newly-built residential buildings will be raised to 75% from October 1, 2116, and the integrated technology of solar energy, light and heat buildings will be popularized compulsorily, the rainwater recycling of buildings will be strengthened, and the construction of a "sponge city" will be promoted.

in p>2115, the energy-saving design standard for residential buildings in Shijiazhuang was 65%, and the new standard of 75% will be implemented from October 1, 2116. All new buildings in the main city should be designed and built according to no less than a green building standard, and construction will not be allowed if the design standard is not up to standard.

the municipal housing and construction bureau issued the notice on strengthening building energy efficiency (hereinafter referred to as the "notice"), which pointed out that in 2116, Shijiazhuang will further strengthen the application of renewable energy in buildings, and force the promotion of solar light-heat building integration technology. All new residential buildings and hospitals, schools, restaurants, swimming pools, public bathrooms (bathing places) and other large hot water consumers in the city must adopt the technology of solar hot water system and building integration. Combined with the actual situation, we will vigorously promote renewable energy and waste heat application technologies such as solar photovoltaic power generation, geothermal energy, sewage source heat and industrial waste heat.

the circular requires that new projects in the city must consider rainwater recycling and adopt the technology of "infiltration, stagnation and drainage", and on this basis, encourage the use of "storage, purification and utilization" technology for rainwater recycling and promote the construction of "sponge city". All new projects use reclaimed water recycling technology in accordance with relevant policies and regulations, and strengthen the maintenance and management of reclaimed water equipment. Vigorously promote the technology of building thermal insulation and structural integration, and accelerate the process of building thermal insulation and structural integration.
