The hottest building energy saving industry report

Report on building energy conservation industry: potential building energy conservation theme 5. Long service life the Political Bureau of the Central Committee of the Communist Party of China conducted the 19th collective learning on the issue of achieving China's action goal of controlling greenhouse gas emissions in 2020 on February 22. On May 5, Wen Jiabao issued the "implementation of energy conservation and emission reduction targets in the 11th Five Year Plan". On June 8, Hu Jintao pointed out in the "eight key scientific and technological fields to promote" that the development and utilization of energy resources, science and technology, should develop energy-saving buildings

building energy conservation is divided into macro and micro considerations. The macro considerations are mainly from the overall structure of the building and the exterior of the building. Curtain walls, photovoltaic building integration (BIPV) and intelligent building design can be used. On the whole, samples with too wide energy-saving appliances are considered. Microscopic consideration of specific building materials

gypsum board: thermal insulation, sound insulation and fire prevention, low production energy consumption, mainly used as internal wall partition. Gypsum board enjoys the support of national policies, with tax reduction and exemption treatment. According to the data in 2004, the per capita consumption of gypsum board in the United States was 10 square meters/person, while that in China was 0. 244 m2/person, China is 1/40 of the United States and 1/20 of Japan. The main production enterprise is Beixin building materials

windows: there are two kinds of energy-saving profiles: plastic steel and Bridge cutoff aluminum. In terms of energy-saving performance, plastic steel is dominant, and the price of plastic steel is much lower than that of broken bridge aluminum, but the wind pressure resistance, fire resistance and durability of plastic steel are not as good as that of broken bridge aluminum. Therefore, both have their own advantages. Plastic steel production enterprises have conch profiles, and the broken bridge aluminum is the building. It is recommended to close 1 and cut other new materials of sequence beams

glass: Low-E glass has the most outstanding energy-saving characteristics. The domestic utilization rate is only about 6%, and that in foreign developed countries is generally more than 70%. It is estimated that the demand for Low-E glass will increase by 50% in 2010 and 72% in 2011. Demand is growing fast. The main production company is CSG

exterior wall thermal insulation materials: polyurethane is the main development direction of wall thermal insulation materials. Among the building thermal insulation materials used in developed countries in Europe and the United States, polyurethane has spent 1398.77 billion yuan on the main business of Enterprises above the manufacturing industry, accounting for 75%, and only about 10% in China. The most important listed companies are hongbaoli and Yantai Wanhua

curtain wall: the energy-saving type of curtain wall is mainly the double-layer curtain wall in the glass curtain wall, which can insulate and keep warm, reduce energy consumption and reduce carbon dioxide emissions. The main production enterprises are AVIC Sanxin, Yasha Co., Ltd. and Golden Mantis

photovoltaic building integration: integrate solar power generation with buildings to not only save energy but also produce energy. Foreign development is based on policy support, and China's policies also support it accordingly. However, at present, the cost of power generation is the bottleneck of promotion. Intelligent buildings: more than 60% of intelligent buildings abroad started in the 1990s in China, and the new construction and reconstruction market is huge

Porter's five forces model shows that the energy-saving materials of building materials with the best prospects are mainly Low-E glass, gypsum board, wall insulation materials, plastic steel and energy-saving curtain walls. Corresponding recommendations: CSG a, Beixin building materials, Yasha Co., Ltd., Dongliang new materials, conch profiles, and AVIC Sanxin. At present, the top four companies are relatively optimistic. These companies are also facing short-term real estate regulation and rising cost pressure

the real estate regulation policies affect the short-term demand for building energy-saving products, and the potential policies increase the long-term market capacity. At present, it is suggested to hide the building energy-saving theme and wait for the building energy-saving policies
