An energy audit of three North Wasco County School District 21 schools has found some mixed results. The Dalles High School and Colonel Wright and Chenowith elementary schools were studied. D-21 Chief Financial Officer Randy Anderson said one recommendation is to modernize the control units of their heating systems. Colonel Wright was of particular concern, with the energy usage 226 percent of average for a school of its size. D-21 officials will now examine the results and begin to prioritize projects that can be undertaken to make the facilities more energy efficient that are also cost efficient, and also weave them into the district’s overall facilities planning process.
