"Numeric thermal bridge simulation in Window Construction Assessment: A Case Study Pertaining to Vacuum-Glass Windows";
Poster: Vienna Young Scientist Symposium 2019, TU Wien, Vienna, Austria; 2019-06-13 - 2019-06-14; in: "VSS - Vienna Young Scientist Symposium June 13-14, 2019", K. Ehrmann, H. Mansouri Khosravi (ed.); (2019), ISBN: 978-3-9504017-9-0; 36 - 37.

This contribution is a work report on recent efforts in the field of computational assessment of contemporary, highly insulating window designs based on vacuum glazing. Thereby, recent developments of the third-party funded project FIVA (Fensterprototypen mit integriertem Vacuumglas - window prototypes with implemented vacuum glazing), follow-up of the successful MOTIVE and VIG-SYS-RENO projects (reported on in previous contributions at the VSS conference series), are discussed.
As already indicated in past publications [1][2], the availability of durable vacuum glass panels allow for the construction of new window constructions, which - if designed in an appropriate fashion - offer a similar thermal performance than conventional triple glazing windows, but featuring smaller system size, thickness, and weight. Based on the ideas developed in the MOTIVE project, the authors could assemble a research and development team together with stakeholders from renowned window construction companies (Internorm, Gaulhofer, Katzbeck, Svoboda, Wick) as well as with stakeholders of supportive technology suppliers (IeB Eisele, Maco). This R&D team is now (ongoing efforts from 2018 - 2020) investigating into progressing the ideas of MOTIVE into higher technology-readiness-levels toward new window constructions for the market that implement vacuum glazing. The project consists of several work packages addressing different aspects, such as fundamental construction principles, implementation of supportive technologies, acoustical performance, and thermal performance of different construction concepts. To successfully establish useful and operable window construction, an iterative ping-pong-process between the technical design work and virtual testing of the thermal performance via numeric thermal bridge simulation was implemented. The specifics of the simulation efforts of window constructions that integrate vacuum glass are illustrated in this contribution.
