I'm not sure if this belongs here or in EC1. This is for a LEED-S 2009 renovation project with an addition. We have updated our energy model input based on the initial design review comments. The Percent Energy Cost Savings are reporting as 26.36% but the points documented is reporting as 9. According to the table for a renovation project, savings above 26% should be worth 10 points. Is it possible that the LEED template is rounding somewhere and is either under reporting the points or over reporting the % savings? I saw a discussion in the water savings calculation with this type of problem.

Assuming the addition is new construction that may be adjusting the thresholds just enough to change the points. With a combination of new and renovation the % savings needed for the points gets adjusted automatically by the form based on a weighted average of the area of new and renovation. The EAp2 form does these calculations correctly as far as I know.

Thank you. This seems to be what is happening, I was not aware that it did a weighted average for this; I guess it makes sense. I wish they were more clear about that when reporting the total points.

Yep it is pretty opaque to the user.
