Wärmetransport und andere bauphysikalische Aspekte im Membranbau.

Research activities with regard to membrane construction at HFT Stuttgart In the presented article we give an overview to some of the recent and ongoing research projects at Hochschule für Technik Stuttgart (HFT) in the context of membrane buildings. One of the major challenges in the context of membrane building is the regulation of the radiative heat flux entering the building as well as thermal losses across the building envelope while still providing comfortable room temperature and daylight use for the inhabitants. The accomplishment of this task, investigated by means of measurements and numerical simulation was the scope of several research projects at HFT Stuttgart. Within the research project "SoFt" the compatibility of insulation and translucency was investigated and realized within the roof construction of a sports center in Germany. One of the objects of the research project "FMESG" was the realization and numerical simulation of an angle‐selective static solution for partial shading, analogous to a miniature saw tooth roof configuration, up to the point of a working prototype. The project "Follow‐e2" tackled the influence of low emissivity surface coatings on the energy balance of membrane constructions by means of numerical simulation. Within the project "FLEX‐G" the potential for reduction of energy demand by dynamic shading with electrochromic elements was investigated by means of dynamic building simulation and heuristic optimization.
