usage. I am certain that ice storage systems have been submitted and
approved in LEED projects. As currently set up you don’t get full
credit since both models must use the same rate structure but you could get
some credit against standard cooling systems if the rate structure favors
off-peak usage.<o:p></o:p></span></p>

since even though these systems save money (which is the basis for
EAcr 1 compliance), they frequently use the same or even more energy than a
standard chiller plant/system design. In other words, in principle, if
your proposed building uses the same or more energy than your baseline, but
shows a $ savings relative to the baseline, is that still valid.<o:p></o:p></span></p>

working on. But, before we run down that route, I'm trying to determine
if LEED considers it an acceptable way to meet EAcr1 and if anyone has been
successfully awarded LEED certification with it. I tried
searching the CIRs, but the LEED search engine didn't return any
matches. There was a little traffic on Bldg-sim on it, but
that was pretty old (2005). I also sent LEED customer service
the questions along with a brief description of ice storage and the
not-so-green as well as green aspects of it. But, it was obvious by
their reply that they had no idea what I was talking about?!?!? <o:p></o:p></span></p>
