　　Beijing to build energy-saving public rental apartments

　　北京建节能公租房

　　A reporter with Beijing Times recently reported that the public rental apartments in the Jiaohuachang area of Beijing will soon adopt new energy saving technologies.

　　根据北京时报最近的报告指出，北京焦化厂附近的公租房将采用最新的节能科技。

　　Three of the buildings will not be equipped with central heating systems. However, with the energy-saving technologies, the apartments in these buildings will nevertheless maintain indoor temperatures between 18 and 22 degrees Celsius. Such buildings are also called "passive homes." It is the first time that this technology is being applied to housing in Beijing.

　　其中三个小区将不配备中央供暖系统。然而，在新兴的节能科技的支持下，房屋室内将保持在18到22摄氏度。这样的房屋被称为“被动房屋”。这是北京房地产第一次采用这样的科技。

　　According to an official at the Beijing Security Housing Investment Center, a building’s outer wall insulating layer is normally 8 centimeters thick; however, the insulation in the energy-saving buildings will be 25 centimeters thick. It is like wearing a down jacket in winter; the heat inside cannot easily escape.

　　根据北京市保障房投资中心一名官员报道，房屋建筑的外围墙绝缘层厚度达到8公分，然而在节能建筑中，绝缘层厚度达到25公分。就像冬天穿着羽绒马甲一样，房屋内的热度是不会轻易扩散的。

　　Meanwhile, each room will be equipped with a central ventilation system, and one of the functions of the system is heat recovery. A special heat storage device will retain the heat and use it to raise the temperature of cool air drawn into the system.

　　然而，每个房屋将会装有中央通气系统，这个系统的一项重要功能就是恢复温度。这个热度储存设备将会保留热气，提升吸到系统中冷空气的温度。

　　During summer, the central ventilation system can be used for cooling, too. The system even has a refrigeration function that can blow cool air into rooms. Although the system has a cooling function, it consumes much less power than air conditioning units installed by individual households.

　　夏天，中央换气系统将可以用于冷却。系统甚至还有冷却功能，可以将冷空气吹入室内。尽管系统具有冷却功能，但是比家庭空调消耗电量要低很多。

　　Currently, the energy saving rate of Beijing’s standard buildings is 75 percent; however, the energy saving rate of these special buildings will be over 90 percent.

　　目前，北京标准住房的能源节约率为75%;然而这些特别的节能房屋的能源节约率可达到90%以上。
