The green development of industry is imperative. In response to the "dual carbon" goal, practicing green and low-carbon social responsibility, and complying with the trend of industry transformation under the concept of green energy conservation, on July 19th, Haier Air Conditioning, in collaboration with Xinhua Network and other relevant authoritative institutions, held the "High Quality Development Forum and Variable Diversion New Technology Release Conference of the Air Conditioning Industry" at the Xinhua Network Media Creative Workshop with the theme of "Green Technology and Low Carbon Life".

Xu Wei, a master of national engineering exploration and design and the president of the Institute of Building Environment and Energy of the Chinese Academy of Building Sciences, stated at the meeting that carbon reduction in the construction field is a prerequisite and important component for China to achieve the "dual carbon" goal. Energy conservation priority is a key means to achieve "carbon peak and carbon neutrality" in the construction field, and it is also the best choice for technology and economy. At present, China's building energy efficiency standard system is complete and has the conditions for large-scale promotion of ultra-low/near zero energy consumption buildings. Considering that the total energy consumption of China's building operation will continue to increase, stronger energy-saving and emission reduction measures should be taken immediately.

Xu Wei believes that architecture is an important carrier for economic transformation, economic development, and the improvement of people's living standards, as well as an important department for achieving the dual carbon strategy. Calculating the total carbon emissions from building operations involves multiple factors such as building area, energy intensity, proportion of fossil fuels, energy emission factors, and carbon sinks. Setting aside external factors, the internal factors that affect building operation carbon emissions include building energy-saving technology, building heating electrification, equipment efficiency, building non heating electrification, and renewable energy utilization.

One of the key tasks of reducing building energy intensity is to improve the quality and efficiency of new buildings, existing buildings and rural buildings. The specific Critical path method includes improving the national mandatory building energy efficiency standards, promoting ultra-low/near zero energy consumption buildings and Zero-energy building, accelerating the in-depth energy-saving transformation of existing buildings, and promoting green and low-carbon rural construction, Increase the proportion of non fossil fuels.

Currently, the world is moving towards ultra-low energy consumption and near zero energy consumption buildings. After several generations of struggle, a solid foundation has been laid in the field of building energy efficiency in China, slowing down the huge demand for building energy brought about by the large-scale development of urban buildings.

Specifically for residential buildings, Xu Wei believes that increasing energy efficiency in air conditioning is to reduce energy consumption, and building energy efficiency is the top priority for improving quality and efficiency. Therefore, it is necessary to use more efficient products and equipment. For over a hundred years, air conditioning technology has been continuously improving and products have been iterating. The variable flow technology released by Haier Air Conditioning today takes into account both summer cooling and winter heating, and the intermediate conversion also considers how to achieve optimal energy efficiency. The pursuit is to improve energy efficiency and dynamic efficiency, in line with the mandatory standards for building energy conservation, which require the use of more energy-efficient energy-saving products and equipment.

China, guided by the goal of achieving carbon peak and carbon neutrality, has promoted green transformation and contributed to the continuous expansion of the global green landscape, becoming an important participant, contributor, and leader in the construction of global ecological civilization. At this forum, numerous industry experts, scholars, and industry leaders interpreted the key decisions for the high-quality development of the air conditioning industry, jointly promoting the green transformation and upgrading of the industry.
