Evaluation of the thermal performance of composite insulated panels with metallic skin through steady-state numerical analysis - Part 1

Abstract

The energy performance of the buildings is a wide spreaded area on which many research is done nowadays. However, because of the relative new large scale interest on it, there still are subjects that have limited research data available. One of this topics is the thermal performance of composite insulated panels with metallic skin, usually a closure solution for industrial halls, production buildings, commercial buildings or even office buildings. Because of the mandatory request of the Energy Performance Certificates (EPCs) in the European countries and in Romania as well, is highlighted that is a lack of informations regarding the thermal behaviour of this type of technical solution and also, synthetic working data for building energy auditors, as linear thermal transmission coefficients values (Ψ-values) for the usually constructive details that compose a regular industrial hall is missing. Therefore, this paper aims to provide an insight about the thermal behaviour of this type of solution, by offering results of Ψ -values for four different dimensions of sandwich panels, which represents appropriate data for a thermal bridges catalogue that may be used directly by the building energy auditors.
