summary |
This research explores adapting architectural material systems as passive dehumidifiers using hygroscopic coatings and material geometry. The study validates increased passive dehumidification through an experimental hybrid lattice system. Human comfort is affected by temperature, humidity, and metabolic heat. In hot and humid climates, elevated tempera¬tures and humidity pose health risks like hyperthermia and mortality (Mora et al. 2017). Historically, vernacular architecture in tropical regions used hygroscopic materials like mud and thatch (Little and Morton 2001; Monzur 2018), to enhance passive cooling through natural ventilation. In contrast, modern construction often relies on mechanical air condi¬tioning, overlooking passive cooling strategies (Korachy 2020). Inspired by vernacular approaches to the built environment, this experiment adapts Isothermal Membrane-Assisted dehumidification (IMAD) technology (Qu et al. 2018) used in mechanical cooling systems to passively extract moisture through hybridization of geometry and matter. While membrane selectivity is adapted to many applications (Woods 2014), its integration into architectural design remains underexplored. Drawing inspiration from Indian Jaali systems, a lattice scaf¬fold is tested to study lattice morphology, and hygroscopic material properties for effective dehumidification at a building scale. Using computational simulation and physical testing, this proposal integrates IMAD into material geometry, focusing on increasing air velocity and passive dehumidification effectiveness (Figure 1).Ultimately, this research aims to rede¬fine architectural design by integrating innovative, passive dehumidification techniques, thus promoting survivability, enhancing human comfort and reducing reliance on mechan¬ical cooling in extreme climates. |
