Tahoe Truckee Unified School District
Independently verified results for Tahoe Truckee Unified School District Administrative Building (Truckee, CA) yielded a 76% reduction in energy usage.

E-minus fitted the Wilo Stratos D 3×3-40 to replace two B&G 7.5 HP 1510 pumps. The ECM motor/pump design considerably reduces space requirements, material and labor cost for owners, contractors, plumbers and electricians. The Stratos D will stage/rotate every 24 hours and optimize the impeller speed according to load. There is no need for external controls; the pump, motor, and computer are self contained and ready to run right out of the box.
