Hygroscopic Envelope explores how 3D printed ceramic facades can enable climate adaptation and resilience by collecting, retaining, and controlling release of stormwater. The research seeks to extend lessons from Landscape-based Stormwater Management Practices and other techniques for storing and infiltrating water, to the architectural facade. It advocates a paradigm shift for the building envelope, away from the conventional “rain screen” notion that facades must repel and shed water off the building, to one that directly engages and manages water in ways that benefit broader infrastructural and ecological systems that are vulnerable to the impacts of climate change. The research explores ways to alleviate the burden on municipal stormwater systems and the demand for intensive mechanical pumping systems that both consume significant amounts of energy and contribute to land subsidence over time. The work operates at three interrelated scales–the micro (material), the meso (component), and the macro (aggregated assembly)–to develop an integrated understanding of how material performance and the design of modular systems can beneficially interface with buildings, landscapes, and other stormwater infrastructures. Two demonstrations are planned, one in Ann Arbor at The Nichols Arboretum and another in New Orleans at the Smart Center.
