at the forum of "smart technology for china's sustainable development" held during the fourth china international expo, johnson controls released the white paper on double carbon goals and sustainable mission of chinese architecture. the white paper focuses on the sustainable transformation of the construction industry, summarizes the seven challenges faced by china's construction industry in the process of implementing sustainable upgrading, and puts forward building life cycle solutions and industry ecological co construction models suitable for multiple application scenarios.
in the outline of the 14th five year plan, construction, industry, transportation and other high energy consuming departments are juxtaposed to become key departments for sustainable transformation. through the analysis of a series of data such as energy consumption in the whole process of chinese buildings, the white paper puts forward the viewpoint of "sustainable city, building first": green and sustainable future urban development largely depends on intelligent and sustainable buildings. the construction industry, one of the main sources of urban carbon emissions, is facing unprecedented challenges. reducing carbon emissions until it is close to "zero carbon emissions" has become the key to the development of the industry.
based on the investigation and research on china's market industry, the white paper on double carbon goals and sustainable mission of china construction puts forward that china has great sustainable potential in reducing building energy consumption demand, optimizing regional energy structure and improving energy efficiency. for example, in terms of optimizing the regional energy structure, the energy foundation estimates that by 2050, about 75% of china's building energy can be used through the electrification of power supply, heating, cooking and water heating terminals, which will effectively control the direct carbon emissions in the building operation stage. in terms of improving building energy efficiency, china began to put forward rigid energy efficiency indicators for new buildings by carrying out pilot work in low-carbon provinces and cities as early as 2010. the ministry of housing and urban rural development predicts that the proportion of green building area in new urban buildings will reach 70% by 2022.
the white paper also summarizes the seven challenges faced by china's construction industry in the process of implementing sustainable upgrading from three aspects: market mechanism, technical path and multi-party cooperation, that is, in terms of market mechanism, construction has great potential for emission reduction but high investment cost; the value of sustainable buildings needs to be recognized and shared. in the technical path, it focuses on the design stage and ignores the whole life cycle; the energy-saving potential is unknown, and there is no way to improve and transform; insufficient data collection and analysis affects judgment and decision-making. in terms of multi-party cooperation, there are challenges to improve the design and implementation level of building energy efficiency across industries; the same is true of coordinating multiple parties to achieve regional emission reduction targets.
combined with the experience of enterprises in the field of construction technology, the white paper makes suggestions on the sustainable development of buildings from the three dimensions of "full life cycle", "full scene application" and "whole industry ecology". the openblue digital solution of johnson controls runs through the whole building life cycle. its products, services and solutions cover green building energy-saving certification consultation, regional energy, efficient products and energy-saving technology, efficient computer room, remote zhilian service, building energy-saving transformation, etc., which can realize all-round support for sustainability and help realize the sustainability of the whole building life cycle.
at the same time, building sustainability can also enable different application scenarios such as medical treatment, industry, transportation and housing, which requires the solution of sustainable building to flexibly penetrate into various scenarios, activate the urban potential and realize the sustainable upgrading of the city and society. in addition, the synergy of sustainable development of the whole industry can be further realized by expanding the participation of sustainable projects, promoting multi-party linkage, and efficiently mobilizing and using resources.
