Veer, F.A. (author), Overend, M. (author), Sofokleous, E. (author), Noteboom, C. (author)Lack of knowledge about the properties of weathered (used) glass is currently a major barrier to glass reuse. This results in probably unnecessary recycling or down-cycling of architectural glass at the end of life. Avoiding this creates a significant opportunity to reduce resource depletion and decarbonize the built environment. This can be...journal article 2023

Justino de Lima, C.L. (author), Aldinger, Brandon (author), de Haan, Peter (author), Bristogianni, T. (author), Veer, F.A. (author)Among the environmental factors affecting glass weathering are humidity, exposure time, temperature, and the presence of pollutants in the atmosphere. Notwithstanding that the weathering produced depends on numerous factors, the important weathering effect of high humidity may be specifically mitigated by using a good chemical composition for...journal article 2022

Veer, F.A. (author), Romein, Ton (author), Buskermolen, P.J. (author)Neglecting the accidental soccer or golf ball hitting the window of the neighbors in a movie, actual impact on glass is rare. In architecture, the only significant case in the literature is where a fully tempered laminated panel of the New York Apple cube was hit by a small stone launched by a snow blower. Nowadays a lot of glass is used in...journal article 2022

Bristogianni, T. (author), Oikonomopoulou, F. (author), Veer, F.A. (author), Nijsse, R. (author)The emerging interest in the architectural applications of cast glass components reveals a knowledge gap on the mechanical properties of cast glass. Apart from its chemical composition, cast glass is characterized by its manufacturing history and thermal profile, often inheriting a set of defects that define its properties. The role that...journal article 2021

Veer, F.A. (author), de Krom, Diana (author), Nijsse, R. (author)A unique structural design was made for the glass façade of the Co-Creation Center building in Delft. The roof is completely carried by the glass fins. The fins are laterally stabilized by being included in the triple glazed façade. To certify the safety of the design full scale tests on the fins were done at Delft University of Technology. Due...journal article 2021

Bristogianni, T. (author), Oikonomopoulou, F. (author), Veer, F.A. (author)Cast glass has great potential for diverse load-bearing, architectural applications; through casting, volumetric glass components can be made that take full advantage of glass’s stated compressive strength. However, the lack of engineering, production and quality control standards for cast glass and the intertwined ambiguities over its...journal article 2021

Bristogianni, T. (author), Oikonomopoulou, F. (author), Yu, R. (author), Veer, F.A. (author), Nijsse, R. (author)Currently, tons of high quality commercial glass are down-cycled or landfilled due to contaminants that prevent close-loop recycling. Yet, this glass is potentially a valuable resource for casting robust and aesthetically unique building components. Exploring the potential of this idea, different types of non-recyclable silicate glasses are...journal article 2020

However, apart from glass bottles, unfortunately, that a large amount of glass will disappear into landfills. This large quantity of unrecycled glass indicates that there is a large potential in upgrading...conference paper 2020
