The Consolidated Forensic Laboratory in Washington D.C. was L.E.E.D.-Platinum certified when it opened in 2012. The $220 million facility has a 20,000-gallon cistern to collect greywater, and panes on the façade that aren’t solar panels like most people think, but are connected to a small weather station on the roof that monitors sunshine and cloud cover, and can be automatically opened or closed to let in just the right amount of solar radiation.
