Low-Cost Building Skin Cools While Using No Energy

Imagine a building that self-regulates its temperature without electronics. A building that adapts, allowing outside air in as needed and eliminating the need for air conditioning, but that uses no energy in doing so.  A University of California-Berkley research team has developed a new type of “building skin” that can do just that, and they are offering their skin as a low-cost option specifically for developing countries.

The team developed SABER, a membrane that wraps around a building instead of walls, filled with micro-scale valves and lenses that open and close as they sense light, heat, and humidity.  It works with no power at all – not even solar PV panels – and keeps the temperature comfortable and light bright inside.
