As China Energy Reduction work progresses, Building energy efficiency Unprecedented attention. Recently held in Tsinghua University and academic sixth week, the experts said, and comprehensively promote building energy efficiency can not only contribute to energy conservation, and will bring building materials, energy-saving products and other related industries, new opportunities for development. Information shows that the total construction in China is the world's largest country, of which 95% are high energy consumers, only existing homes for energy saving on hold the more than 2 trillion yuan of business opportunities. Not blindly praise the new technology Low carbon buildings do not have to use a lot of new technology, a large number of energy-saving construction is not necessarily new technology used in energy, this concept has become part of the Building Energy Conservation Week participants academic consensus. Recent years, renewable Energy Use has been the key energy-saving architecture evaluation, the industry appears blind pursuit of new technology, the result is a number of projects in the use of renewable Energy Technology, the actual energy consumption rise, not fall. "We do not praise those who piled up a lot of new technology, zero-energy, negative energy buildings, but to the idea of harmony with the natural environment from the start, as far as possible to rely on passive means to create human life and working space." Ministry of Housing and Urban and Rural Construction Energy Conservation and Technology Deputy Director Hanai Xing said. Engaged in green building assessment system of the Department of Architecture, Tsinghua University, Professor Zhu Ying mind that many renewable energy is low grade energy, but the process has to be high-grade energy consumption, such as Heat Pump Water heat recovery, exhaust heat recovery wheel, Solar Energy Collector techniques must consume a large amount of electrical energy. Therefore, in considering the benefits of renewable energy when the cost must be considered. Ying-Xin Zhu said that building the use of renewable forms of energy should have a choice, should encourage low-cost energy-saving construction example of conventional technology, including low-cost passive means should be preferred. Should encourage low-cost, efficient and appropriate technology, to avoid the blind pursuit of high-tech, the building into a pile of expensive high-tech products, in fact, fail to meet the purpose of energy saving. Seize new opportunities for the development of New building energy efficiency of the idea of making people reconsider building energy efficiency, will also create new opportunities for development. China Project Academy Yi Jiang said that in recent years in building energy efficiency in the practice of many effective techniques, but some technology not yet mature. China has a huge market space, hope and commitment to building energy-saving technological innovations of equipment manufacturers be able to grasp business opportunities, positive development. To accelerate energy conservation, and Commerce will be expanded this year, the green and carbon exchange of technical cooperation with the United States and Canada, Germany, Britain, Sweden and Japan, Australia and other countries in green building and low-carbon Ecological City Construction exchanges and cooperation in the field, through the exchange of exploring for energy in China's construction industry development approach. Yi Jiang that China in resources, energy, population, economic development levels, cultural traditions have their own characteristics, therefore, promote energy conservation, the method can not blindly copy foreign to our own realities. On the one hand to learn from other countries of advanced energy-saving technology and experience, we must also proceed from the actual situation in China, to explore with Chinese characteristics, adaptation to climate and cultural characteristics of China's energy-efficiency, to promote science, sustainable energy use habits and life. Urgently improve the evaluation system and evaluation criteria Industry experts point out, our support and promotion of energy efficiency in the green building aspects and the lack of an effective incentive mechanism, especially to improve the low-carbon green building assessment system and evaluation criteria. Zhu Ying mind that building energy efficiency as the future development trend of the real estate industry, real estate developers have not caused enough attention and active participation, mainly because of lack of domestic evaluation criteria and incentives. Hanai Xing, this year China's green building rating will be identified as the main handle, accelerate the improvement of evaluation standards, strengthening evaluation mechanisms to promote the evaluation of identification systems, organizational reporting "low-carbon eco-city planning and construction of key technology research and demonstration" projects and launched a low-carbon eco-city grade evaluation criteria, planning and construction of key technology R & D and demonstration. Present, public buildings, energy conservation has been some success. In 2005, the former Ministry of Construction and the State Administration of Quality Supervision jointly issued a "public building energy efficiency design standards," which is the first public building comprehensive national standards for energy efficient design. The standard building energy-efficient technology as the basis and guidelines. In the industry, improving building energy efficiency standards at the same time, the need to gradually improve the certification rules, the field of building energy-saving green building materials relevant to the needs of technical and product certification system. The building energy model of development, China has conducted a number of attempts. However, the development needs of local governments and energy efficient building strong co-operation of real estate developers, will the Government policies to promote and guide the market advantage and real estate developers in the capital, technology, technology and personnel to combine the advantages of establishing a sound and green benefits associated with the system architecture to fully mobilize the enthusiasm of all parties. Order to comprehensively promote energy efficiency, building energy efficiency of Housing and Urban Rural Development and Technology Division will increase this year, implementation of energy efficiency standards for new buildings the supervision, actively promoting energy management contract pilot demonstration, start high-energy public buildings for energy saving. In addition, will develop and implement building energy policies promote the use of new materials.
