ANOTHER KIND OF SOLAR PANELS
// FACC 3.0
a speculative design rooted in biophysics, questioning form and function
problem
most building facades are static surfaces. when they produce energy, it’s usually through solar panels that only capture light. this leaves other environmental resources unused, while cities continue to rely on fossil-based grids.
concept
living facades use algae bioreactors embedded into panels or glass systems. instead of just harvesting sunlight, they convert carbon dioxide and water into biomass, creating a renewable source of energy and heat while also filtering air.
design logic
the system works by circulating microalgae in transparent modules on the facade. sunlight drives photosynthesis, biomass can be collected for biofuel, and the process generates thermal energy as a byproduct. unlike pv, algae integrates biological cycles into architecture, turning the building skin into an active organism.
potential impact
algae facades could transform buildings into urban biofactories: reducing carbon, producing energy, and reshaping how we see city surfaces. beyond performance, they challenge the idea of facades as inert. the message: energy generation doesn’t have to be silicon. it can be alive.
