Water scarcity is a conundrum that affects every continent. Approximately 1.2 billion people (or 1/5 of the world’s population) live in areas of physical scarcity, and another 1.6 billion people face economic water shortage, relays UN-Water. To help remedy this conundrum, BMDesign Studios developed an innovative roof that is capable of collecting rainwater and cooling homes in arid environments.
The Concave Roof which looks like a bowl sits on top of a domed roof. When it rains and water is collected, the life-saving resource is funneled through the bowl into cooling reservoirs. Space between the double roofs allows for wind circulation and shade.
The architects explain that the 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.” Considering hot, dry climates can be almost unbearable for residents during the summer, this intriguing concept has a variety of positive implications.
