(Sub)Ambient: The Planet-Centric Cooling Material
Sustainable Passive Cooling Material
Heat and cooling are bound together in a vicious cycle. The hotter it gets, the more energy is needed for cooling, and the more waste heat warms the environment. (Sub)Ambient solves this climate feedback loop by providing electricity-free cooling even in direct sunlight. Designed for roof installation, it is based on a combination of ultra-reflectivity within the solar spectrum and ultra-emissivity across the atmospheric window (8-13µm). Better yet, its unique combination of CaCO3 microparticles and cellulose nanofibers is derived from food waste (eggshells) and is 100% biodegradable.
This is a great example of a design solution that is both technically innovative and simple in its application. The designers just need to think about a form factor that can be better commercialized and a usage application that can be brought to market.
