本論文は、室内湿度を受動的に制御し淡水を生成する太陽光駆動の吸着フィルムを提案する。1時間で相対湿度を90.7%から21.6%に低減し、約1.1 kg/m2/日の淡水を生成する。世界規模の試算では、建物エネルギー消費を29.9 kWh/m2/年、炭素排出を16.5 kg/m2/年削減し、回収期間は48日である。この技術は湿度を負荷から資源へと転換し、自律的な植物灌漑も可能にする。
English
This paper presents a solar-driven adsorption film that passively dehumidifies indoor air and produces freshwater. It reduces relative humidity from 90.7% to 21.6% in one hour and generates ~1.1 kg/m2/day of freshwater. Global projections show energy savings of 29.9 kWh/m2/yr and carbon reduction of 16.5 kg/m2/yr with a 48-day payback. The film enables autonomous plant irrigation and reframes humidity as a recoverable resource.

📄 Abstract（原文）
ABSTRACT Indoor humidity strongly affects both building energy demand and occupant health in hot and humid climates, but it remains largely controlled by energy‐intensive mechanical systems and is seldom exploited as a source of freshwater. Here, we demonstrate a passive humidity regulation and freshwater harvesting strategy enabled by cost‐effective adsorption films (18.79$·m −2 ) that couple moisture capture, storage, and release within indoor environments. The films rapidly reduce relative humidity from 90.7% to 21.6% within one hour while maintaining long‐term operational stability and release the captured moisture to produce freshwater at a rate of approximately 1.1 kg·m −2 ·day −1 under ambient conditions. Leveraging the harvested water, an autonomous plant irrigation system is achieved, enabling sustained regulation of indoor CO 2 concentration (about 920.2 ppm) without manual intervention. Global‐scale projections indicate that this passive approach could reduce building energy consumption by up to 29.9 kWh·year −1 ·m −2 and associated carbon emissions by 16.5 kg·year −1 ·m −2 , with an exceptionally short payback period of 48 days. This work reframes indoor humidity from a latent load to a recoverable resource, offering an integrated route towards water harvesting, energy reduction and healthier indoor environments in sustainable buildings.
