The background of the topic is to compare the colour changes at different irradiances and temperatures at constant relative humidity. The issue is important because evaluation in terms of irradiance has not been studied in more detail. Irradiation intensities were reported in many studies but tended to have metadata status. The concrete influence of the irradiance on chemical and colour changes in the wood remains open. This paper presents an approach to inquiry-based teaching within a basic research project. Initial results from a large-scale data series are presented here. Irradiance is the term for the total power of incoming electromagnetic energy striking a surface, related to the size of the area, measured in watts per square metre [W/m²].
Keywords: artificial irradiation, wood, indoors, temperature, CIE Lab, colour changes
