Testing and Analysis on Thermal Performance for Prefabricated Thermal Insulation Composite Wall Panel of an Office Building

The main objective of this study is to explore prefabricated thermal insulation composite wall’s thermal performance in the project. Using infrared thermal imager and multi-point heat meter takes a test on office building envelope. The test results showed that the composite wall temperature change delay of 3 hours 12 minutes, the temperature change attenuation of 2.5 °C; The composite board exterior wall surface temperature attenuation is larger and the thermal stability of the structure is perfect; thermal bridge is the main reason for reducing the average thermal resistance of the wall.
