Our cities are heating up nearly twice as fast as the global average. By 2050, the urban population exposed to extreme temperatures is estimated to increase by 800%. This growth will yield a corresponding momentous increase in energy demand for cooling. Meanwhile, our prevailing cooling technology contributes to a warming globe, exacerbating the very issue it seeks to mitigate. Oversky is a project that explores the capacity of a new urban infrastructure system, leveraging passive technologies, to cool our cities. Inspired by clouds, the modular system is designed to canopy and mitigate the effect of the areas largely responsible for the urban heat island effect, road networks and parking lots, reclaiming this space for people while cooling down the city.
