Henriksen, T.N. (author), Lo, Stephen (author), Knaack, U. (author), Kirkegaard, Poul H. (author)The main bottleneck during the manufacture of complex geometry thin-walled GFRC structures is the time taken to make the timber or CNC machined moulds for each panel. Complex geometries are comprised of many unique panel forms and the extensive time and high costs of their manufacture often prevents their architectural intent from being fully...journal article 2022

Balderrama, A. (author), Kang, Jian (author), Prieto, Alejandro (author), Luna-Navarro, Alessandra (author), Arztmann, Daniel (author), Knaack, U. (author)Façades cover a significant amount of surfaces in cities and are in constant interaction with the acoustic environment. Noise pollution is one of the most concerning burdens for public health and wellbeing; however, façade acoustic performance is generally not considered in outdoor spaces, in contrast to indoor spaces. This study presents a...review 2022
