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

Abstract:

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.
