Designed by Iranian architecture firm BMDesign Studio, the Concave Roof is a double domed roof that collects rainwater to keep homes cool. Perfect in arid countries such as Iran, the roofing system is an environmentally conscious way to keep interiors comfortable in very high temperatures. Consisting of two domes balanced on top of one another, the Concave Roof not only addresses rapid rates of evaporation with its bowl design, it also offers shade below.
The cooling system is an example of how living in an extreme climate can be made more efficient without the use of solar panels.
In the future, BMDesign Studio hopes to alter the domed roof to be suitable for partially submerged structures.
