Second, the use of renewable building materials. Most of the buildings in Germany are treated using local native wood as the main building material. Such materials consumed in the growth process with minimal energy and produce the least carbon dioxide, both at the house after the demolition and reuse can be degraded. Third, focus on energy-saving renovation of existing buildings. On the one hand the development of relevant rules and regulations Shijiazhuang insulation board manufacturers, to boot from the policy level to encourage businesses and individuals to modernize the energy-saving technological transformation of the old building, and the compulsory retirement measure; on the other hand the introduction of the energy-funded projects to promote legislation implementation and universal. Fourth, using a variety of eco-energy saving technologies. Germany developed and implemented a variety of ecological energy-saving technologies, including rainwater recycling, sewage waste recycling, building insulation process, biodegradable technologies. As an important building energy-saving technologies, exterior insulation has been highly worldwide attention Laizhou insulation board manufacturers, countries have begun the implementation of the actual wall of the building energy conservation target. Tracing the source of the insulation board manufacturer, in the 1940s in Sweden and Germany, has been 70 years of history of this technology originated, after years of practical application and the test of time under different climatic conditions worldwide, the use of such proof insulation system architecture, either from outside the building or the decorative effect of the degree of comfortable living, is a worthwhile worldwide promotion and application of energy-saving technologies.
