This special issue of the Journal of Facade Design and Engineering (JFDE) is linked to the conference FAÇADE 2018 – Adaptive!, the fifth conference that has been organised by Lucerne University of Applied Science and Arts within the framework of the European Façade Network, EFN. FAÇADE 2018 is also the final conference of the COST Action TU1403 ‘Adaptive façades network’ (www.tu1403.eu) and dedicated to multifunctional, adaptive, and dynamic building envelopes.

The PowerSKIN Conference aims to address the role of building skins to accomplish a carbon neutral building stock. Topics such as building operation, embodied energy, energy generation and storage in context of envelope, energy and environment are considered.

The focus of the PowerSKIN issue 2021 deals with the question of whether simplicity and robustness stay in contradiction to good performance of buildings skins or whether they even complement each other: simplicity vs. performance?
