GB 50189—2005《公共建筑节能设计标准》至今已发布执行10年了。随着国家节能工作的深入开展、暖通空调技术的发展和能源价格的提升,原有的节能设计标准中关于管道与设备绝热条文的内容已不能满足使用的需求。为此,本次修编依据介质温度、能源价格、气候条件、绝热材料等不同条件,对暖通空调和给排水工程中常用的冷热管道和设备提出绝热要求,其适用范围更广、划分更细。 GB 50189-2005 “Design standards for energy efficiency of public buildings” has been released for 10 years. With the deepening of national energy conservation work, the development of HVAC technology and the promotion of energy prices, the contents of the original energy saving design standards on the insulation of pipes and equipment can no longer meet the needs of use. To this end, this revision based on medium temperature, energy prices, climate conditions, thermal insulation materials and other different conditions, the HVAC and water supply and drainage projects commonly used in hot and cold pipelines and equipment adiabatic requirements, its wider scope of application, the division thinner.
