Jianke Environmental Energy Technology Co., Ltd. (hereinafter referred to as "Environmental Energy Technology") is a technology-based enterprise under the China Academy of Building Sciences Co., Ltd. (hereinafter referred to as "China Academy of Building Sciences"). The predecessor of the enterprise, the Air Conditioning Research Institute and the Building Physics Research Institute, were established in 1957, and the Building Environment and Energy Research Institute was integrated and established in 2006. In the "Science and Technology Reform Demonstration Action" of state-owned enterprises, Environmental Energy Technology is integrated and established based on the Institute of Building Environment and Energy, shouldering the core mission of "responding to the national carbon peak and carbon neutrality strategy goals, leading the development of the building energy and environment industry". It is a technology-based enterprise that continuously promotes the transformation and technological progress of China’s construction industry, has sustained innovation capabilities, and market competitiveness. In February 2023, it was selected as one of the first batch of "world-class specialized, refined, and innovative demonstration enterprises" by the State owned Assets Supervision and Administration Commission. Currently, Huaneng Technology has 456 employees on duty, of which 65 hold senior professional titles, 120 hold deputy senior professional titles, and 142 hold intermediate professional titles; On the job, 49 people hold doctoral degrees and 203 people hold master’s degrees. Huaneng Technology has attracted overseas students from well-known universities or research institutions in countries such as the United States, the United Kingdom, Japan, and Canada, and has introduced multiple high-level professional technical and management talents from China. Currently, it has formed a hierarchical research team consisting mainly of young and middle-aged experts, and a combination of old, middle-aged, and young talents. Environmental Energy Technology focuses on application research and technological development in the fields of building environment, building energy, green buildings, intelligent buildings, low-carbon buildings, etc. It is committed to solving key technical problems in HVAC, building sound, light and thermal engineering, and has a strong industry influence in sub sectors such as heating and air conditioning, biopharmaceutical purification, near zero energy buildings, zero carbon buildings, and renewable energy building applications. In the field of scientific research and standards, Environmental Energy Technology has completed 973 research projects of various types and levels, including 12 national key research and development projects, 26 projects, and 51 sub projects, leading the industry nationwide. A total of 423 standards have been completed, and 107 standards are under development. At the same time, the internationalization of standards is promoted through the International Organization for Standardization, and international technical exchanges are strengthened based on international standards and English versions of standards; To carry out national academic exchange activities through platforms such as associations, associations, and international academic organizations, and provide a public welfare platform for the development of the industry. In the field of design and planning, we mainly engage in design businesses such as comprehensive architectural planning and design, specialized planning and design, biological purification and safety. In the field of consulting and services, we mainly engage in technical consulting services in the fields of building environment and energy, zero carbon buildings, near zero energy buildings, intelligent buildings, green buildings, biopharmaceutical purification, renewable energy applications, building curtain walls, and sound, light, and heat.
