From The Lexington Herald-Leader: The doors at the new Wellington Elementary School in Lexington, Ky., opened today. Wellington, one of two new schools joining the Fayette County system, is loaded with green features in keeping with the district's growing emphasis on sustainability. Solar tubes collect and focus sunlight into the building. Windows are oriented to make maximum use of daylight. Rainwater from the school's roof is routed into an underground 50,000-gallon storage tank. It will be used to flush toilets, reducing the building's city water costs.
