After conducting a five-month audit of energy usage at the City/School Administration Building in Rapid City, students from the South Dakota School of Mines and Technology identified $10,000 worth of potential savings annually for the city. As reported by the Rapid City Journal, some of the recommendations made by the student team include updating the current lighting system to LED technology. The initial cost of updating the lighting would be $49,000 and would be recovered in three years’ time.
Additional recommendations included an excess of office equipment and use of space heaters and fans as a result of inefficient heating and cooling systems. Students conducted the energy audit at no cost to the city.
