NC-2009 EAp2: Minimum Energy Performance
The CIR 10426 (http://www.usgbc.org/content/10426) creates the impression that in locations where the local code does not require vestibules they are not mandatory, if a "a narrative explaining how infiltration and exfiltration of air through building entries is addressed in the design" is provided and the defined energy penalty is applied to the modelled energy savings.
Is this interpretation correct?

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?

That is what I read.

If I am not mistaken by including vestibules we do not have to calculate the infiltration through the entrances and therefore it is not required to include this in the energy model, is this assumption correct?
