<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Keep in mind that the model for the baseline
building requires heating and cooling for conditioned spaces. The boiler room
itself may qualify as a semi-heated space, which will change the cooling
requirement. Take a look at Appendix G of ASHRAE 90.1-2004 for details.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>The huge process load will definitely make
it hard to reduce the overall energy consumption. You may be able to limit the
process load in the model to 25% of the overall load. Take a close look at the
LEED-NC Reference Guide. Good luck!<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I recently received a request to model a large boiler plant.
The plant is actually a major renovation, so major the project is going for
LEED-NC. Before I start gathering materials for the model I want to make sure I
have the correct approach in place.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>My understanding is that I will need to model the whole
building with the mechanical portion being served by ventilation fans and the
auxiliary spaces served by heating/cooling systems. The boilers will be metered
as process loads and all other mechanical equipment will act the same as in a
“standard” energy model. I am concerned about meeting and exceeding
the two point requirement for EA credit 1.<o:p></o:p></span></font></p>
