Abstract

This paper investigates the potential of 3 market available transparent insulation materials (TIM) in building retrofit by the case study of the iconic1970ies housing estate Terrassenhaussiedlung in Graz, Austria. To achieve this, different façade configurations are modeled in a 2D-simulation environment (HTflux) and tested in a dynamic simulation environment (IESVE) for different orientations and overshading situations. The results show that that even low-tech TIM can outperform conventional insulation materials in terms of heating energy demand, when applied to façade areas with high solar exposure, while only transparent aerogel can compete with conventional insulation materials on badly exposed areas.
