Upcoming ENERGY STAR Portfolio Manager Updates
Did you know 1-100 ENERGY STAR scores are based on average nationwide energy performance? The latest data is in, and U.S. buildings are becoming more energy efficient! Portfolio Manager will be updated on August 26, 2018. Portfolio Manager users will see changes in ENERGY STAR scores and source EUIs. To learn more and get tips to prepare, visit www.energystar.gov/scoreupdates.
What does this mean for Better Buildings partners?
- Since the U.S. building stock is becoming more energy efficient, buildings will see, on average, a drop in their ENERGY STAR scores. The change in score will depend on each property’s energy use, fuel mix, business activity, property type, and other variables. See the ENERGY STAR website for additional details. While the ENERGY STAR score provides a valuable comparison to peers, Better Buildings uses Source EUI rather than ENERGY STAR scores to track progress toward energy goals, so score changes will not impact Better Buildings results.
- Source EUI values will be slightly lower across all years while improvement over time will remain generally consistent. This is because the source energy conversion factor for electricity is changing from 3.14 to 2.80 in the baseline and current year as well as all interim years.
- Additional use details will be available for several property types noted below. These should be updated in order to get the most accurate adjusted source EUIs and ENERGY STAR scores.
- Worship facilities
- K-12 schools
How can I prepare for these changes?
- Historic data used in previous Better Buildings Data Review Reports are already saved.
- You can also download “before and after” score changes for individual buildings or portfolios from Portfolio Manager. See these step-by-step instructions for how to generate the “Performance Highlight” report (a portfolio-level, multi-year summary) and the “Statement of Energy Performance” (a building level, 12-month performance period) in Portfolio Manager.
