Rescuing School Budgets with Renewable Energy

As the new Richardsville Elementary School rose from its foundations on a rural road north of Bowling Green, Ky., fourth-grader Colton Hendrick was watching closely. He would climb to the top of the playground equipment across the street and watch construction crews hauling in bamboo flooring and solar panels.
“He wants to be an architect some day,” recalled Manesha Ford, elementary curriculum coordinator and leader of the school’s energy team. “He would sit and draw, draw all the different aspects.”
But Richardsville Elementary would not only capture Hendrick’s imagination—it would come to inspire his classmates and school districts around the world. When Richardsville opened its doors in fall 2010, it was the first “net zero” school in the nation, meaning that the school produces more energy on-site than it uses in a year.
Solar tubes piping sunlight directly into classrooms eliminate much of the school’s demand for electric light, while a combination of geothermal and solar power cut down on the rest of the energy bill. Concrete floors treated with a soy-based stain don’t need buffing. The kitchen, which in most schools contributes to 20 percent of the energy bill, houses a combi-oven that cooks healthier meals and eliminates frying. This means an exhaust fan doesn’t pipe the school’s temperature-controlled air to the outdoors all day long. Meanwhile, “green screens” in the front hall track the school’s energy usage so kids can see the impact of turning off a light in real time.
These and other innovations make Richardsville better than net zero. It actually earns about $2,000 a month selling excess energy to the Tennessee Valley Authority.
But building a green school isn’t enough, according to architect Philip C. Gayhart, principal in the architecture firm Sherman Carter Barnhart, which built Richardsville and has helped the Warren County School District achieve Energy Star ratings for 17 of its 24 schools.
Three factors are essential to making a green school work: First, you need the participation of the community and the local power company; second, you can’t forget that a school is a dynamic learning environment; and third, you need to speak the language of money.
Green by necessity
Since the economic recession began in 2008, school districts have suffered. Local tax bases were shaken as property values plummeted, and states have cut back on funding to districts, which were pushed to cut funds wherever they were able. Addressing energy use made a lot of financial sense.
Few states have been harder hit than Arizona, where the 21.8 percent decrease in per-pupil spending was the highest in the nation.
Sue Pierce, director of facility planning and energy with the Washington Elementary School District in Phoenix, watched as teacher positions were cut, furlough days were scheduled, and $6 million in annual facilities funding disappeared.
“We saw that energy was really an area where we could perhaps save money by simply changing behavior,” Pierce said. “I approached the superintendent and asked permission to develop a program.”
The district’s new energy policy aimed to cut energy consumption district-wide by 10 percent in the first year and 40 percent over the next five years. As part of the program, Pierce began to distribute monthly reports on energy usage, which included every school in the district.
Some schools took to the program more quickly than others.
“Just by changing behaviors, they were showing 10 and 15 percent reduction the first or second month,” she said. The reports then fueled a competition between schools, and by the end of the first year, energy use had been cut 15 percent district-wide.
