Scope

Building energy-saving materials are an important foundation for achieving green building, low-carbon development, and the "double carbon" strategic goals. Their thermal performance directly relates to the insulation and heat insulation effect of building envelopes and the overall energy efficiency level. Key indicators such as the thermal conductivity, thermal resistance, and heat storage performance of materials not only determine the energy consumption during the operation phase of buildings, but also affect living comfort and environmental quality. With the continuous emergence of new energy-saving materials such as high-performance insulation boards, composite insulation walls, vacuum insulation materials, aerogels, and phase-change energy storage materials, the application scope of building energy-saving materials has become more extensive, and their performance characteristics have become increasingly complex. Compared with traditional materials, these new materials place higher demands on testing methods, requiring not only attention to conventional physical parameters but also consideration of durability, environmental adaptability, and functional stability. At present, there are still differences in the detection methods of the thermal performance of building energy-saving materials. Different laboratories lack unified standards in testing conditions, equipment selection, and data processing, resulting in insufficient comparability and authority of testing results. Some testing institutions also lack experience in test design and quality control, which easily leads to data deviations and affects engineering application and market promotion. To solve the above problems, this document proposes key points for the detection of the thermal performance of building energy-saving materials, systematically sorting out the aspects from detection preparation, method application, quality control to result determination. The document aims to provide a unified techni
