Procaccini, Giulia (author), Prieto, Alejandro (author), Knaack, U. (author), Monticelli, Carol (author), Konstantinou, T. (author)The European building stock demands urgent renovation due to the age of the buildings, their expected lifetime, and their excessive energy consumption, which accounts for more than a third of the EU’s total emissions. However, the complexities involved, such as time, costs, and structural modifications, often discourage clients, tenants, and...journal article 2024

Bierach, C.B. (author), Alberts Coelho, A.A.C. (author), Turrin, M. (author), Așut, Serdar (author), Knaack, U. (author)Under urgent sustainability targets, the building industry craves for renewable and recyclable biomaterials as cellulose is a fiber; Lignin is a plant-derived low-cost polymer with remarkable properties, yet its valorization is in its infancy. Recent studies have shown potentials to combine cellulose and lignin into a renewable bio-based...journal article 2023

Hamida, H.B. (author), Konstantinou, T. (author), Prieto, Alejandro (author), Klein, T. (author), Knaack, U. (author)The global attention to solar cooling systems has increased during the last years as a result of the expected growth in the world cooling demand. Such systems encompass the use of renewable energy as the main driver for mitigating indoor temperatures. Currently, some of these technologies are mature enough for their commercial application in...conference paper 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

de la Barra Luegmayer, P. (author), Luna-Navarro, Alessandra (author), Prieto Hoces, A.I. (author), Vásquez, Claudio (author), Knaack, U. (author)Several studies performing building simulations showed that the automated control of façades can provide higher levels of indoor environmental quality and lower energy demand in buildings, in comparison to manually controlled scenarios. However, in several case studies with human volunteers, automated controls were found to be disruptive or...journal article 2022

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
