Piping and equipment insulation thickness revision in GB 50189-2015 Design standard for energy efficiency of public buildings

GB 50189-2005 Design standard for energy efficiency of public buildings has been issued for 10 years. With the in-depth development of national energy saving work, the development of HVAC technology and rising of energy price, the terms on piping and equipment insulation in original energy design standard can not meet the actual demand. Therefore, the revision is based on different conditions, such as medium temperature, energy price, climate conditions and insulation materials. In the HVAC and water supply and drainage project, proposes the insulation requirements for common used cooling and heating pipes and equipments, and these requirements are with more extensive application and more detailed division.
