The construction industry and its members of the whole industrial chain must clarify the standards of carbon emission reduction and carbon neutralization in urban and rural construction projects, and minimize energy consumption and carbon emissions in accordance with the standards of carbon emission reduction and carbon neutralization in the whole life cycle of each precast building (including design, material selection, logistics and storage, processing and manufacturing, installation, maintenance, operation management and other links).

● prepare systematic solutions to reduce energy consumption.

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

The energy surplus generated by it can be exported to the outside world, trade energy and carbon emission indicators, create economic benefits, and meet the needs of national defense and disaster emergency.

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

It is entirely possible to formulate systematic solutions for them, so as to make a great contribution to carbon emission reduction and carbon neutralization.

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

● formulate carbon emission reduction and carbon neutralization standards.

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

Under the conditions of modern high-tech technology and industrialized manufacturing process, the assembled integrated building can produce new energy.

The main factors of carbon emission from existing buildings include: all materials, facilities and equipment used in the construction process 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, operation and management; Carbon generated in the process of building relocation, demolition or equipment transformation, installation, decoration, decoration and parts supporting..

● redefining precast buildings.

To study the carbon emission of the construction industry, it is necessary to clarify all energy consumption categories and quantities in the whole life cycle of buildings.

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

Grasp the key link of construction industry, implant dual carbon concept and technology, sort out ideas, formulate dual carbon target strategy and guide the implementation of the industry.

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

● factors causing carbon emissions from existing buildings.

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.

Welcome to leave a message at the bottom of the article to participate in the discussion and look forward to your voice ~ author Hu Yongsheng, chairman of the Professional Committee for urban and rural integrated development of China Association for the promotion of urbanization, China’s “14th five year plan” is based on the measures of carbon emission reduction, carbon neutralization and environmental sustainable development, strengthen the measures to control carbon emission, and walk out of a more scientific, healthy, environmental friendly, clean and low-carbon road of modern human living, production and life.

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

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

The development of all walks of life is inseparable from construction.

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

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

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

The scientific and technological R & D capacity, processing and manufacturing capacity, installation capacity and management capacity of China’s construction industry are in a leading position in the world.

In the era of traditional construction industry, the energy consumption, environmental pollution and carbon dioxide emission incidental to the transformation of natural resources into materials and products belong to an unlimited and unplanned way.

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

The steps for the construction industry to achieve carbon emission reduction and carbon neutralization include: formulating standards and evaluation objectives; Calculate the best value of carbon balance and strictly follow it; Optimize and simplify the cluster and low-carbon production and manufacturing process of precast construction industry; Reduce the use of building materials and the energy resource demand of logistics and warehousing; 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 resource-based classified collection, recycling and reuse of sewage and garbage at the source; Realize the digitization, integration and systematization of architectural design, production, manufacturing, installation, maintenance and operation management.

Therefore, we should re evaluate and plan the development of precast building manufacturing in many aspects and the whole system.
