Abstract: In this article we report on our investigations on the impact of dynamic shading, integrated into ETFE fenestration elements, on the energy demand of buildings, via numerical simulation. The numerical investigations are carried out with the dynamic building simulation suite TRNSYS. The dynamic shading mechanism is based on electrochromic elements. The modelling of the electrochromic dynamic shading mechanism is based on data from commercial as well as newly developed elements. We explore the general potential for the reduction in overall energy demand in relation to various switching algorithms. The influence of the switching algorithm is explored by employing the optimization tool GenOpt.
