The energy surplus generated by them can be exported for energy and carbon emission index trading, creating economic benefits and meeting the needs of national defense and disaster emergency.

Therefore, it is necessary to re evaluate and plan the development of the precast building manufacturing system.

used in the construction of buildings and the carbon generated by their production processes; Carbon generated during construction logistics, storage, manufacturing and installation; Carbon generated in the process of building use and operation management; Carbon generated in the process of building relocation, demolition or equipment transformation and installation, decoration, decoration and parts supporting..

● redefine precast buildings.

Change the traditional construction concept through the upgrading and transformation of the concept, reposition the construction industry, promote the precast integrated building, so that the building is no longer an energy consumer, but a space carrier for the production of new energy.

It is completely possible to formulate systematic solutions for them, thus making great contributions to carbon emission reduction and carbon neutralization.

The scientific and technological research and development capacity, processing and manufacturing capacity, installation capacity and management capacity of China’s construction industry are all in the leading position in the world.

Under the conditions of modern high-tech technology and industrialized manufacturing technology, precast integrated buildings can produce new energy.

● formulate green and low-carbon development strategies and put them into action.

● factors of carbon emission from existing buildings.

The construction industry and its members of the whole industrial chain must define the carbon emission reduction and carbon neutralization standards in urban and rural construction projects, and reduce energy consumption and carbon emissions to the minimum according to the carbon emission reduction and carbon neutralization standards during the whole life cycle of each precast building (including design, material selection, logistics and storage, processing and manufacturing, installation, maintenance, operation and management).

According to statistics, the carbon emissions of the construction industry account for 38% of the global carbon emissions, but the total carbon emissions of the upstream and downstream supporting parts, facilities and equipment, decoration and other industries of the comprehensive construction industry account for 70% of the global carbon emissions.

● steps for the construction industry to achieve carbon emission reduction and carbon neutralization.

China adds about 2 billion square meters of building area every year.

In the era of traditional construction industry, the energy consumption, environmental pollution and carbon dioxide emissions generated by the transformation of natural resources into materials and products are unrestricted and unplanned.

We should grasp the key link of construction industry, implant double carbon concepts and technologies, sort out ideas, formulate double carbon target strategies, and guide the implementation of the industry.

Promote the development of renewable new energy industry, energy transportation and storage industry and low-carbon industry under the premise of low carbon, and promote the comprehensive development of green low-carbon precast buildings and urban and rural construction.

● formulate carbon emission reduction and carbon neutralization standards.

In the process of urban and rural construction, precast buildings can play a leading role.

It is expected that in the next 10 to 20 years, China’s new precast buildings will account for more than 50% of the global total.

The main factors of carbon emissions from existing buildings include: all materials, facilities, equipment, etc.

By changing the concept, integrating various professional technologies, processes and equipment in the construction process of precast buildings into an integrated system, clarifying the target positioning of “double carbon” planning and evaluation, systematic and scientific integrated design, industrial cluster processing, manufacturing, installation, maintenance, and digital whole process operation management, the energy input demand of buildings can be effectively reduced and the production function of green new energy can be increased.

● prepare systematic solutions to reduce energy consumption.

If we do not formulate planned and restrictive systematic solutions to the energy consumption of the construction industry, the energy consumption and carbon emissions of the whole industrial chain of the construction industry will rise correspondingly.

The construction industry must clearly define the plans and limits for reducing energy consumption and total carbon emissions, so as to ensure that the overall environmental level of China remains within the scope of sustainable development.

China’s 14th five year plan is based on carbon emission reduction Carbon neutralization and environmental sustainable development initiatives, strengthen measures to control carbon emissions, and embark on a more scientific, healthy, environmental friendly, clean and low-carbon modern human living, production and life path.

The development of all industries can not be separated from construction.

Reducing energy consumption and carbon emissions of China’s construction industry and buildings and further refining carbon emission reduction actions are very important for achieving carbon emission reduction and carbon neutralization goals.

In order to reduce the energy consumption and carbon emissions of the construction industry, it will be very important to take further actions to limit the total carbon emissions to achieve the goals of carbon emission reduction and carbon neutralization.

The steps to achieve carbon emission reduction and carbon neutralization in the construction industry include: formulating standards and norms and assessment objectives; Calculate the best value of carbon balance and strictly follow it; Optimize and simplify the industrial cluster and low-carbon production and manufacturing process of precast buildings; Reduce the use of building materials and the energy resource demand of logistics storage; Select green materials and new energy products that have little impact on the environment; Use energy-saving and low-carbon materials and technologies to reduce the demand for electricity, water and gas in buildings, take buildings as the space carrier for the production of new energy, and realize the classified collection of sewage and garbage sources, recycling and reuse; Realize the digitization, integration and systematization of architectural design, production, manufacturing, installation, maintenance and operation management.

Construction ideas under the “double carbon” objective to study the carbon emissions of the construction industry, it is necessary to clarify all energy consumption categories and quantities in the whole life cycle of the building.
