Has anyone entered November energy data in Portfolio Manager and looked at the score? I hope you weren't counting on the energy points your project had before November.
"New National Median Benchmarks
Effective November 7, 2011, EPA will introduce new National Median performance targets within Portfolio Manager. The median value represents the middle of a distribution: half of the buildings have better energy use intensity (EUI) values while the others have worse EUIs.
The new National Median performance targets will replace the National Average values that are currently in Portfolio Manager. That is, for all instances where a national average is currently displayed, the value will be replaced with a National Median. EPA is making this change because the National Median has been determined to be a better benchmark point of comparison for existing buildings."

Always good to print out a "Statement of Energy Performance" before any changes to Energy Star Portfolio Manager are scheduled to occur.

Chris,
If the period of performance is finished before the change and you take print screens of the portfolio manager data it might work out. The issue with the change from mean to median is that it appears for many of the building types the energy performance is harder by at least 24%. That's potentially a huge difference in resultant points for the same energy use. I'm all for accurate benchmarking, but I don't like the rule change in the middle of the game.

I noticed that the Case 2 Calculator has not been updated since the November Portfolio Manager update. Will buildings still be benchmarked against the average source EUI (instead of median source EUI)? We have a customer building in the entertainment/culture category and if we go by the case 2 calculator, which has an avg. source EUI of 265 to benchmark against, the project gets 15 or so points. If we benchmark against the median source EUI of 94, which is now in Portfolio Manager, the project doesn't even meet the EAp2 pre-req. Which should we go by?
