Urban and rural construction is one of the main areas of carbon emissions. Recently, 8 departments including the Provincial Department of Housing and Urban Rural Development and the Provincial Development and Reform Commission jointly issued the "Action Plan for Carbon Peak in the Field of Urban and Rural Construction in Henan Province" (hereinafter referred to as the "Plan"), which clearly proposes to further increase the contribution of green buildings, green communities, green building materials, energy and resource utilization to social carbon reduction.

8 departments in Henan jointly issued a document! Fully implement green building standards for new urban buildings by 2025

In order to further accelerate the development of green buildings, in recent years, our province has successively introduced a series of demonstration and promotion policies and technical standards for ultra-low energy consumption buildings, proposing policy incentives in areas such as financial subsidies, non capacity area incentives, and green credit. Building energy use has gradually achieved clean and low-carbon, and the proportion of clean energy and renewable energy applications has gradually increased.

The Plan points out that by 2025, a new pattern of green development in the field of urban and rural construction will initially take shape. New buildings in cities and towns will fully implement the green building standards, and the proportion of prefabricated building will strive to reach 40%. The transformation of old residential areas that need to be transformed will be basically completed before 2000. The creation of urban green communities will reach more than 60%. The collection, transportation and harmless treatment of urban domestic waste will be fully covered, and the utilization rate of resources will reach more than 60%, We will basically achieve full coverage of rural household waste classification and resource utilization. By 2030, the direct carbon emissions in the field of urban and rural construction in the province will reach a peak, and the policy system, institutional mechanisms, and standard system for green and low-carbon development in urban and rural construction will be basically established. The structure and methods of building energy use will be more optimized, the quality of buildings and engineering will be further improved, the quality of ecological environment and living environment will be significantly improved, green lifestyles will be widely formed, and green and low-carbon operation will be preliminarily realized.

To achieve the expected goals, the Plan proposes two key tasks: to carry out the construction of green and low-carbon cities, and to create green and low-carbon counties and villages.

Carry out the construction of green and low-carbon cities

By 2025, the proportion of green buildings in newly built buildings in the province will reach 100%

Urban morphology, density, functional layout and construction mode have an important impact on carbon emission reduction. The plan requires optimizing the urban spatial layout and promoting cluster development. Scientifically control the density and height of urban construction, promote the "white space and greenery" of cities, strictly restrict the construction of buildings over 250 meters, and construct buildings over 100 meters in a relatively concentrated layout that is suitable for the size and spatial scale of the city. For existing buildings, strict demolition management should be implemented, and the area of demolished buildings in urban renewal units (areas) or projects should not exceed 20% of the current total construction area.

Improve the operational efficiency of municipal infrastructure, promote waste classification, reduction, and resource utilization, and achieve full coverage of urban household waste collection, transportation, and harmless treatment by 2025, with a resource utilization rate of over 60%. Promote the green construction of urban lighting, and by 2030, the proportion of efficient and energy-saving lighting fixtures such as LEDs will exceed 80%, with over 30% of cities having digital lighting systems. Strengthen the construction of ecological garden cities and strive to create four national ecological garden cities by 2030. The urban built-up areas have greenways with a length of over 1 kilometer per 10000 people.

We will comprehensively improve the level of green and low-carbon buildings and promote green and low-carbon construction. By 2025, the proportion of green buildings in new buildings in the province will reach 100%, and the proportion of newly started prefabricated building in the area of new buildings will strive to reach 40%. The renovation of old residential areas that need to be rebuilt will be basically completed before 2000. By 2030, the proportion of star rated green buildings will reach over 30%, and government investment in public welfare buildings and large public buildings will all reach one star or more. Projects invested or participated in by the government will fully adopt green building materials.

Promote the construction of complete communities, and increase the coverage rate of complete residential communities in prefecture level and above cities to over 60% by 2030. Optimize the energy consumption structure of urban construction, vigorously promote the application of solar energy technology, and strive to reach 50% of the photovoltaic coverage of the roof of new buildings and new plants of public institutions by 2025. Use geothermal energy according to local conditions, and guide the development of building electrification.

Building green and low-carbon county towns and villages

By 2025, we will basically achieve full coverage of rural household waste classification and resource utilization

The "Plan" requires the province to carry out the construction of green and low-carbon county towns. The population density of the built up areas of county towns located in ecological functional areas and main agricultural product production areas should be controlled between 6000 to 10000 people/square kilometer, and the ratio of total building area to construction land should be controlled between 0.6 to 0.8. New residential buildings should mainly have 6 floors, with a maximum of 18 floors. The proportion of building area for residential buildings with 6 floors and below should not be less than 70%. The width of the red line of the internal roads in the county seat shall not exceed 40 meters, and the area of concentrated hard land in the square shall not exceed 1 hectare.

Promote the construction of green and low-carbon villages and green and low-carbon rural houses, guide the promotion and application of the "Energy Efficiency Design Standards for Rural Residential Buildings", and improve the energy efficiency level of rural houses. Encourage the use of local materials and local materials, promote the use of green building materials, and encourage the use of prefabricated building. Improve the collection, transportation and disposal system of rural household waste, ensure the normal operation of "cleaning, transportation, treatment, and maintenance", and basically achieve full coverage of rural household waste classification and resource utilization by 2025. Promote the application of solar energy, geothermal energy, air thermal energy, biomass energy and other renewable energy in rural gas supply, heating, power supply and other aspects.
