Conceived of as an ‘intelligent, all-electric’ building, The Crystal -- built by Siemens, that global powerhouse in renewable energy tech, among other things — is the center of London’s new Green Enterprise District in Newham. The building, which opens on September 19, was intended to serve as a showcase for innovative green building tech running the gamut from solar power arrays (which cover the roof of the building) to ground source heat pumps tied to geothermal wells (buried beneath the building site). As you might imagine, the development also showcases sustainable building technologies from the Siemens’ Environmental Portfolio, characterized as ”the largest and most comprehensive in the world.” The Crystal treats all of its own wastewater on site, and was designed to take top marks in both LEED and BREEAM (UK) certifications; no fossil fuels will be used to power the building.
