"Exploring the technical requirements of vacuum glazing for contemporary window constructions";
Poster: VSS VIENNA young SCIENTISTS SYMPOSIUM, TU Wien; 2018-06-07 - 2018-06-08; in: "VSS - Venna young scientists symposium", P. Hans, G. Artner, J. Grames, H. Krebs, H. Mansouri Khosravi, T. Rouhi (ed.); Book-of-Abstracts, (2018), ISBN: 978-3-9504017-8-3; 80 - 81.

Vacuum glass has been considered as a potential solution for energy-efficient transparent building assemblies. In recent years, the industrialized production of vacuum glazing has become more common. It can be expected that such products will be more frequently deployed in the building sector. Previous efforts in research and development mainly focused on the development of the vacuum glass itself, due to the challenges regarding durability of the glass (specifically, long-term preservation of vacuum in the interstitial space). Less attention has been paid to the construction detailing of windows equipped with vacuum glass. The properties of vacuum glazing are different from those of regular insulation glass. Thus different approaches to window construction are required. This contribution presents the structure and findings of a recent research project, focusing on design and construction of windows with vacuum glazing. Thereby, various performance aspects of different frame/glass constructions were examined. The thermal performance, one of the research foci within this project, was assessed in a two-fold manner: On the one hand, knowledge of previous studies pertaining to vacuum-glass application in historic window constructions was obtained and processed. On the other hand, numeric thermal bridge simulation was applied to evaluate different frame designs and to derive their performance indicators. Moreover, in the framework of the project, different innovative window detailing approaches were explored using simulation and functional prototypes. This contribution provides an overview of the research project, developed window construction designs, and their performance.
