and question why you have such a peak demand. For instance if the peak
demand only occurs for 2-5 minutes and the rest of the day you average 20-40% off
your peak you might have a schedule problem (i.e. fans, pumps, heating coils,
all turn on at the same time). Otherwise if your peak demand is pretty
consistent with the actual load heating load this is entirely possible.<o:p></o:p></span></p>

While it is not common, sometimes depending on the utility rate structure
and/or mechanical systems this does happen. For example, the 1 Bryant
Park (Bank of America) building while it received many LEED EA credits (and a
LEED platinum rating) did not really save that much if any in total energy
use. The reason for this was its use of an ice storage system which
shaves off the peak demand and moves it to off-peak times such as during the
night. As long as the utility rates and model were built correctly, I
would rest assured that your results are accurate.<br>

structure is approximately 1 cent per kWh and $12 per kW. All the heating

Since LEED is based on energy cost, is it safe to assume that the my building
will achieve the 5 points? Has anyone run across this situation. <o:p></o:p></span></p>
