Tired of hearing about building integrated photovoltaics? Well, the next wave of energy-producing architecture may look quite different. Strawscraper, a project currently underway in Stockholm, will see a building coated in a hair-like material that harvests energy from the wind. The process is known as piezoelectricity. Designed by Swedish firm Belatchew Arkitekter, Strawscraper is an addition to Stockholm’s Söder Torn building, which was completed in 1997. Once transformed into the Strawscraper, the building will stand at 40 stories tall and will act as an “urban power plant,” according to the architect’s website.

As the name suggests, the the building’s facade will be coated in thin straws, which will be agitated by the wind in a continual flowing movement. At nighttime, the building will be mde even more lively with colored lighting illuminating the swaying straws. This type of wind energy technology is much quieter compared to wind turbines and is able to collect energy from mere breezes. The Strawscraper will also feature a public observation deck offering views of the city below.The current Söder Torn building (Courtesy Belatchew Arkitekter)
