This topic was discussed in a Tuesday debate at the TH-OWL with Mic Patterson, Prof. Dr.Winfried Heusler and Prof. Daniel Arztmann as panel members on 8th June 2021 in a transatlantic online forum, sponsored by Schüco. The discussion was conducted by Prof. Jasper Jochimsen on what shall be the future of façade skins.
The debate started by statements of the panelists who introduced keywords like embodied energy, circularity, resilience, climate change and healthy buildings and environments. According to the following panel discussion carbon emissions need to be cut down by 7.5% each year for over a decade to keep global temperature rise to under 2°C. In addition to carbon emissions in the operational phase, construction materials include large amounts of embodied carbon which must be considered in life cycle assessment. A holistic design approach that considers the long-term durability potential of the diverse and Ambiguity) are challenges for the future what necessitates the design of resilient facades which are proactive, responsive, flexible, robust and adaptive.
Modularity of facades was another key concept discussed by Prof. Dr. Winfried Heusler. While talking about post pandemic trends, health aspects are coming into focus and will have a significant influence on future architecture and thus also on developments in the field of building envelopes. To make this development sustainable, we need climate-neutral building envelopes that ensure an optimal quality of life inside and outside buildings, even with changing requirements as suggested by Prof. Daniel Arztmann.
