[Bldg-sim] credit for space heating based on campus steam

[Ramana Koti]

Dear all,

For LEED EA Credit 1:

How does proposed design model take credit over a baseline design model in
terms of increased space heating efficiency in a setting where the building
is using steam from the campus central facility? Is there something in
ASHRAE 90.1 that addresses this?
Is the efficiency of the steam producing equipment and the source-to-site
efficiency constant between the two models?

Thanks,

Ramana Koti.
