This paper research applied to using energy-saving insulation in hot summer and warm winter area of sandwich wall panels, study on thermal insulation thermal insulation property of composite wall panel through 2 sets of thermal performance test, and the test results for comparative analysis with finite element analysis results. The analysis shows that the wallboard is not only good insulation properties, but also to meet the requirements prescribed by the state building energy-saving insulation and hot summer Cold Winter areas of building energy-saving insulation requirements.

A phase change material (PCM) is an energy storage mass with high heat storage performance. In buildings, PCMs can be utilized to save energy in radiant floor heating systems. This study aims to analyze the thermal performance and energy saving potential by the PCM radiant floor heating system based on wet construction method and hot water. For such analysis, EnergyPlus program was used. As for the results, it was found that the proposed system almost maintained the set point of indoor air and a floor surface. Moreover, when a 10 mm PCM was applied, it was possible to save 2.4% of heating energy annually compared to existing buildings. In particular, when a 20–50 mm PCM was applied, it was found that 7.3–15.3% of heating energy was reduced annually. If indoor air temperature exceeds the comfort range of the proposed system, this problem can be solved by adjusting the set point of the floor surface or by increasing the temperature of hot water.

Based on the energy saving design standards in hot summer and cold winter zone like Anhui province, a new type of sandwich insulation composite wall panel is researched, Influence on thermal performances of new sandwich insulation composite wall panel,due to in different thermal insulation material, different content of the oblique connection rebar, different thermal insulation layer thickness and different internal and external wall thickness, are analyzed. The results show that, in not take extra insulation measures, this kind of sandwich insulation composite wall panel thermal performance can meet the hot summer and cold winter area energy-saving design standard requirements. Research results and practical engineering contact tightly, It has a comparatively high practical value.
