   @article{Cheng2024, abstract = {In response to the global challenge of reducing carbon emissions and energy consumption from regulating indoor climates, we investigate the applicability of biobased cellulosic materials and bioinspired 4D-printing for weather-responsive adaptive shading in building facades. Cellulose is an abundantly available natural material resource that exhibits hygromorphic actuation potential when used in 4D-printing to emulate motile plant structures in bioinspired bilayers. Three key aspects are addressed: (i) examining the motion response of 4D-printed hygromorphic bilayers to both temperature and relative humidity, (ii) verifying the responsiveness of self-shaping shading elements in lab-generated conditions as well as under daily and seasonal weather conditions for over a year, and (iii) deploying the adaptive shading system for testing in a real building facade by upscaling the 4D-printing manufacturing process. This study demonstrates that hygromorphic bilayers can be utilized for weather-responsive facades and that the presented system is architecturally scalable in quantity. Bioinspired 4D-printing and biobased cellulosic materials offer a resource-efficient and energy-autonomous solution for adaptive shading, with potential contributions towards indoor climate regulation and climate change mitigation.}, author = {Cheng, Tiffany and Tahouni, Yasaman and Sahin, Ekin Sila and Ulrich, Kim and Lajewski, Silvia and Bonten, Christian and Wood, Dylan and R{\"u}he, J{\"u}rgen and Speck, Thomas and Menges, Achim}, day = 28, doi = {10.1038/s41467-024-54808-8}, issn = {2041-1723}, journal = {Nature Communications}, month = {11}, number = 1, pages = 10366, title = {Weather-responsive adaptive shading through biobased and bioinspired hygromorphic 4D-printing}, url = {https://doi.org/10.1038/s41467-024-54808-8}, volume = 15, year = 2024 }
