Building-integrated fog collectors
Building-integrated fog collectors (BIFCs) are systems that incorporate fog-harvesting functions into architectural elements such as façades, roofs, or shading devices. Unlike freestanding large fog collectors (LFCs) deployed in open terrain, BIFCs aim to capture airborne water droplets directly on the external skin of buildings. In this way, building envelopes perform a dual function: they provide protection from weather and climate while simultaneously acting as devices for collecting water. BIFCs belong to a broader class of building-integrated environmental technologies that seek multifunctional envelopes.
