I learned of a rather fascinating building in downtown Cleveland today. The five-story office complex is being billed as a “green building” and is being used as a model. There are solar panels and raised bed gardens on the roof. Energy saving motion sensor lights are used in the hallways. Parking lot runoff, sometimes tainted with car oil an anti-freeze, is filtered through a green space as opposed to just emptying directly into a storm sewer. The interior walls are painted with a non-toxic, vegetable paint base — with just a faint smell of broccoli.
