Abstract

The need for zero-energy building is increasing as a means of actively responding to climate change. Since pipe insulation is a factor that minimizes heat loss of cooling and heating facilities, it is necessary to check pipe insulation standards and prepare improvement plans of preparation for certification of zero energy buildings. In this study, domestic pipe insulation standards were checked to prepare new insulation standards based on energy performance. Through the development of a pipe insulation calculation program, the heat loss according to the insulation thickness of the piping for mechanical facilities was compared and reviewed. As a result, applying the insulation thickness of the KCS standard for the same conditions increased the heat loss by an average of 10% compared to the ASHRAE standard. For this reason, it is necessary to revise the pipe insulation thickness standard in consideration of heat loss due to thermal conductivity and pipe insulation thickness. Using the program in this paper, it is possible to design pipe insulation based on energy performance and help to determine the standard for pipe insulation thickness.
