metric in LEED (ASHRAE 90.1) is energy cost not energy 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>

<DIV>
<P class=MsoNormal><SPAN
style="FONT-SIZE: 10pt; COLOR: black; FONT-FAMILY: 'Arial','sans-serif'">I'm
just curious if they considered this a valid way to meet EAcr1 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></DIV>

<P class=MsoNormal><SPAN
style="FONT-SIZE: 10pt; COLOR: black; FONT-FAMILY: 'Arial','sans-serif'">We're
considering looking at ice storage for a LEED project I'm 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></DIV>
