it was recently learned that the new standards for energy efficiency of residential buildings in Beijing have been approved and will be implemented from July 1. In the future, Beijing's buildings should pay special attention to building energy conservation. Through the adoption of new technologies and standards, the residential houses that can be used for stretching, tightening, zigzagging, tearing, shearing, 180 degree stripping and 90 degree stripping experiments should be as warm in winter and cool in summer as possible. Beijing will also become the first city in China to implement the 65% energy-saving building design standard

it is reported that the new standard has two characteristics: first, it has changed from the original energy saving of 50% to energy saving of 65%. The measures to further reduce energy consumption are entirely borne by the enclosure structure, external walls, roofs, external doors and windows, rather than shared by the enclosure structure and heating as before; Second, different from the previous standard which only considers heating in winter, according to the climate characteristics of Beijing, the principle of the new standard is to focus on heating in winter and give consideration to the energy saving of air conditioning and refrigeration in summer. In the future, the exterior window glass may be developed from ordinary single-layer glass and double-layer glass to hollow, inflatable and low radiation glass. The requirement for the wall is that the external wall insulation has developed from the internal insulation in the past to the current external insulation as the leading technology. It is reported that the implementation of the new standard will not significantly increase the construction cost of poly (butylene terephthalate)
