The Glacial Drumlin Middle School construction was audited by Alliant Energy and received their highest rating, both due to its energy efficient construction with a well designed building "envelope", daylighting and a highly efficient HVAC system with geothermal source. Alliant is certain that the building will receive Energy Star certification. More importantly they estimate savings of $114,000 per year (at current energy costs) over more conventional construction. The extra investment in energy efficient construction will be paid back in savings pretty quickly.
Based on these savings Alliant is offering us a low interest loan that we could use to perform energy efficiency improvements elsewhere in the district. Hopefully we can net additional savings while at the same time reducing the environmental footprint of the district.
