[Bldg-sim] FW: LEED system selection for GSHP<BR><BR>Thanks for all the
comments. This is for LEED EA Credit 1. The system has no fossil
fuel supplementation, so PSZ-HP it is. The poor baseline benefits the
project in terms of LEED points, however, this leads to something I've been
thinking...<BR><BR>Why not use the same baseline for all buildings? Or
at least make baseline system selection appropriate for different climate
zones. This baseline would make choosing electric resistance heat look
somewhat reasonable in this climate. Use of electric resistance heat is
actually no longer legal in the state of Vermont for commercial
construction.<BR><BR>~Karen~<BR><BR>

interpretation -- the system would be 4-PSZ-HP – assuming you are using the
2004 edition of ASHARE 90.1. The User's Manual states that if the heating
energy source for the proposed building is electricity, then the heating
energy source for the baseline building has to be electricity too. This
system would not actually be used in Wisconsin either. Fortunately for me,
the utility programs that I model for allow me to use "engineering judgment"
(common sense), so I can use a realistic system for the baseline. But if you
have to go by the book, then 4-PSZ-HP it is! I can see how this could
overstate the savings for a ground-source heat pump system in a cold climate
like ours.</SPAN></FONT><BR><FONT face=Arial color=navy><SPAN
