This report discusses energy efficiency enhancements made to a low energy, high performance office building. The building studied is the Iowa Association of Municipal Utilities headquarters located in Ankeny, Iowa, just north of Des Moines. Monitoring the energy use of the building for over six years has revealed that it has an average annual site energy use of 29, 300 Btu/ft2. This is 68% less energy than that used by the average U.S. office building and 74% less energy than the average office building in climate zone 2, the location of Ankeny.Table 3.2 shows the present value of the natural gas used by the HVAC systems, the present value of the electricity used by the entire IAMU office building over the life of the systems, the present value of the operating and maintenance costs ofanbsp;...
