This Concave Roof System Collects Rainwater in Arid Climates

Iran-based BMDesign Studios has unveiled Concave Roof, a double-roof system with steep slopes resembling a bowl for the purpose of rainwater collection in arid climates like Iran, where a lack of water could lead to mass displacement in the future.

Because precipitation in this area is less than one-third of that of the world average, and evaporation is more than three times higher than the world average, the concave roof system is designed to “help [make] even the smallest quantities of rain [flow down] the roof and eventually coalesce into bigger drops, just right for harvesting before they evaporate” explained the architects.
