(Waupun) The Waupun School District commitment to energy efficiency was recognized with a check for $90,000. During a ceremony Monday night, the renewable resource program Focus on Energy presented the school with the check following energy-saving upgrades the district undertook as part of a $36-million dollar referendum. Improvements included lighting enhancements to classrooms and office spaces in all district buildings, lighting upgrades to the gymnasium, locker rooms and the newly constructed greenhouse and TechEd Center at the Waupun Junior/Senior High School. The annual savings on utility costs is estimated to be around $78,000 and equates to reducing carbon dioxide emissions by over 1,000 tons, the equivalent of taking 154 cars off the road. Waupun District Administrator Steven Hill says these improvements will help the district save money on energy costs for years to come and helps make their buildings comfortable during inclement weather conditions. The $90,000 will go towards funding projects such as building improvements, furnishings or equipment.
