Hi,

This has been bogging us for a while, as we cannot figure out how to
interpret the various issues in ASHRAE 90.1.

If in a multifamily building the residential units are only heated but
not cooled in the actual design (climate is North Europe), how does the
baseline get modeled? I suppose Systems #9 and #10 (Heating Only) would
be out of the question as these are intended for ancillary spaces. So it
would have to be System #1 or #2, but with cooling as well?

More importantly, would the Proposed residential units be modeled with
additional cooling using identical systems as in Baseline?

Thank you in advance,
