Yes, all scores, including all historical scores, will be updated in mid-August 2018. We need to do this so you can see your change in energy use over time. If we didn't update historical scores, you would not be comparing "apples to apples" in your metrics.
After we do the update, your previous scores will no longer be accessible in Portfolio Manager. If you want to save your current scores before they're updated, run the “Performance Highlights” report or create a custom report in July 2018. We will send out reminder emails to all Portfolio Manager users in advance of this update.
Previous ENERGY STAR certifications will not be affected by these score updates.
We recommend pursuing 2018 certification prior to June 2018, in case your property’s score changes, rather than waiting for the 2018 update to go into place.
