Original Abstract

Buildings are subject to strongly time variable solar radiation impacts, which are phenomena that typically occur at a characteristic timescale resolution. Recent technologies and advances which are currently being used to produce polycarbonate-based materials may be used in applications where it is useful to activate the solar transmittance functions of building envelopes. In general, systems utilizing polycarbonate as a type of transparent insulation material exhibit the thermal performance of standard glazing systems. This study is focused on the optical characterization of several polycarbonate panels for buildings that are based on different numbers of chambers and differing geometries. The optical performance was analyzed in order to monitor the long-term solar properties of polycarbonate panels, by means of outdoor measurements in order to demonstrate the impact of year-round aspects on solar transmittance. This represented a specific methodical approach incorporating real full-scale components. Finally, the solar transmittance is evaluated with regard to the various outdoor time scales (hourly/daily, monthly and year-round). The studied multi-wall polycarbonate panels indicate that they may have very specific characterization from the solar transmittance perspective regarding the solar radiation that penetrates throughout their internal structure. The solar transmittance of polycarbonates, to which the timescales of the outdoor conditions respond, may significantly vary. Overall, the differences in total solar transmittance for laboratory, declared and outdoor test methods are very obvious; they differ by tens of percent. The study provides an initial insight into the optical behaviour of polycarbonate multi-wall panels and a very large set of data in order to make careful use of these parameters concerning their specificity and time dependent characteristics in thermal analysis of building integration.
