Energy Performance

Better Buildings Challenge Partners are tracking their energy use at a facility-level, demonstrating the power that data can bring to managing energy and reducing energy bills. Partners have shared data from their baseline year to current energy usage to document progress towards meeting their energy reduction commitment. Based on first year results, Partners improved the energy intensity of their portfolios by more than 2.5% per year since their baseline years, in line with President Obama's goal to reduce by 20% the energy intensity in the commercial and industrial sectors by 2020. The energy performance improvements equate to 8.5 trillion Btus and $58 million in savings per year. The substantial facility-level improvements achieved by all Partners are summarized in the graph below. Partners that have provided energy data for 2012 are listed at the bottom of this page. Detailed results on progress to date can be viewed for many Partners, with additional results coming soon.

Understanding Energy Use Intensity (EUI)

Program progress is measured in terms of energy use intensity (EUI) to account for changes in Partner portfolios over time. For commercial buildings, EUI is generally measured in terms of energy use per square foot, and can be useful in comparing energy use of facilities of different sizes. Industrial facilities also use EUI to measure progress, but alternative EUI metrics are generally used to reflect the outputs and processes at the plants. Some common metrics for measuring energy intensity in industrial facilities include energy use per pound of product, vehicles manufactured, labor hours, or dollars of revenue. For both commercial and industrial facilities, EUI values are commonly adjusted to account for changes in weather from year to year and changes in operating conditions over time.
