CS-2009 EAp2: Minimum Energy Performance
Advanced Energy Modeling for LEED states "Existing buildings with less than 50% renovation should not be rotated,...". How can one calculates renovation percentage of an existing building?

For an existing building, do I need to rotate the model?
Our process load is higher than 25%. Do we have to justify that?
Our local code references ASHRAE 90.1-2010. Should I use that for my documentation, or 90.1-2007?
Can mezzanines open to floors below be excluded from the energy model?

Existing building in general do not need to be rotated. The percentage of renovation should not matter.
If you could cite the page where this quote comes from that would be helpful. I searched the document using the quote above and it did not turn up.

Thanks Marcus, It is on page 7 under Baseline Case, Building Envelope column at the end of second paragraph.

The percentage of rennovation makes no sense at all. Perhaps it was attempting to refer to an addition that is greater than 50% of the exisiting triggering the rotation. I don't know of any requirement to do so but maybe it is in a LEED Interpretation.
