BLDG-SIM@gard.com<BR>Subject: [BLDG-SIM] LEED and evap chillers<BR><BR>I think
you're right. The problem with that is that it provides no incentive with
respect to EAcr1 to go with a more efficient evaporatively-cooled chiller if
you've already decided not to pursue a fully water-cooled option (due to
first-cost constraints, space limitations, etc.).<BR><BR>Would this be arguable
in a CIR?<BR><BR>Thanks,<BR>Wade<BR><BR><BR>> -------Original
