NC-2009 EAp2: Minimum Energy Performance
Hello,
Can someone let me know if ASHRAE 90.1 2010 is acceptable to use in relation to lighting or is 90.1 - 2007 still required to be used? I have read the FAQs above, but want to make sure that information is still true.
Thanks,

A portion of our building envelope is historic. Can we exclude it from our model?
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?

You can use any addendum to 90.1-2007. I am not sure if any of the lighting changes resulted from an addendum. If not then you should not be using them. I am not sure why you would want to do so as they will likely reduce your energy savings due to the more stringent baseline.

Hi Marcus,
Thanks for the reply. I probably should have put a little more context in the question. This question is actually in relation to CI 2009 EA1.1, but the NC page seems to get more traffic, so I figured I would ask here. Our COMcheck LPD was done using 2010 standard because of local code, so I wasn't sure if I needed to have the MEP redo the calculations with 2007.

The 2010 would probably get accepted because it would be a conservative approach, however you may score better if you use 2007.
