Water-Filled Glass: Fluid Architecture and Liquid Engineering

Water-filled Glass (WFG) is an innovative glazing system that transforms glass from a passive barrier into an active energy regulator. By circulating water, WFG absorbs and redistributes heat, reducing energy demand. In summer, it captures heat before it enters; in winter, it prevents heat loss. Inspired by natural intelligence, WFG mimics Earth’s climate system and stabilises temperatures through movement rather than resistance. WFG is ideal for retrofitting, installable inside buildings without major disruption. This scalable solution could cut emissions by 500 million tons annually, redefining energy efficiency beyond insulation-based approaches.
