Uau Studio's Algae Tower: A Bio-Facade That Grows, Shades, and Generates Energy

Uau Studio, led by Gianluca Santosuosso, has designed the Algae Tower, a proposal for an office tower in Melbourne, Australia, that integrates photo-bio-reactor technology into its facade. The bio-facade, inspired by tree canopies, uses micro-algae cultivated within transparent containers to provide shading, absorb carbon dioxide, and generate renewable energy through photosynthesis. The system adapts seasonally: denser in summer to improve shading and biomass production, more transparent in winter to allow passive heating. The design analyzes solar radiation across the building envelope to optimize module density, dimensions, and placement for both energy production and environmental performance. The project addresses heat waves' impact on the built environment, offering an alternative to static glass facades that contribute to solar heat gain and cooling demands. The facade functions as a large-scale photo-bio-reactor, producing biomass for biofuel and capturing CO₂, with potential to reintegrate emitted CO₂ into the cultivation cycle.
