Prospect Sierra School implements a school-wide program that includes efficient water usage, conservation of electricity, and reduction of waste, using, among other tools, the EPA Energy Star Portfolio Manager and UC Berkeley's Cool Climate Calculator to track energy and water consumption. The school has installed solar panels, waterless urinals, and an energy efficient boiler, and is piloting a new low-emissions transportation system for students to get to school. The facilities manager oversees the safe disposal of batteries and fluorescent tubes. In their place, the school retrofitted lighting that now brightens 44,000 square feet of buildings with energy-efficient ballasts and tubes. In addition, the school is moving away from desktop computers toward lap tops and iPads, reducing computer waste.
