<DIV><SPAN class=539082315-09122008><FONT face=Arial size=2>I have a 36 story
office building that I am trying to model the current energy usage in and have
run into a question about losses in a steam distribution system. Not having much
experience modeling large office buildings using a steam distribution system, I
was wondering what to use for my supply losses for the system. I know that it is
hard to make a generalization on a typical supply loss Delta T because so many
factors come into play depending on the system, but I just want to make sure I'm
in the right ball park on my estimate. I'm currently using a 1ºF temperature
loss. The pipe is insulated pretty well and all the traps were replaced about 10
years ago. I don't really know the total length of steam piping, but it is
distributed to 36 floors for perimeter heating only. Any suggestions or advice
would be helpful. Thank you.</FONT></SPAN></DIV>
