<P class=MsoNormal><FONT color=navy size=2 face=Arial><SPAN
style="FONT-FAMILY: Arial; COLOR: navy; FONT-SIZE: 10pt">Expanding on what Bruce
said, consider that equipment nameplate electric values tend to be substantially
higher than in real life. If you are currently using nameplate equipment values
as the basis for your <st1:place w:st="on">Watts</st1:place> / sf model inputs,
it could be unrealistically increasing both the electric energy consumption of
the equipment itself and the energy required to condition the space.

<P class=MsoNormal><FONT color=navy size=2 face=Arial><SPAN
style="FONT-FAMILY: Arial; COLOR: navy; FONT-SIZE: 10pt">FYI, if you have an
ASHRAE 2009 Fundamentals Handbook, check out Tables 6 and 7 on pages F18.11 for
nameplate and recommended heat gain rates from typical medical equipment (or see
attached). You’re probably not modeling each individual blanket warmer (I hope!)
but it gives you an idea of how substantially actual conditions can differ from
nameplate. <o:p></o:p></SPAN></FONT></P>

<P class=MsoNormal><FONT color=navy size=2 face=Arial><SPAN
style="FONT-FAMILY: Arial; COLOR: navy; FONT-SIZE: 10pt">As Bruce also
mentioned, make sure a utilization schedule is applied to whatever peak value
you come up with so that it is not running at 100% all the time. It sounds from
your email like you may already have a schedule applied to prevent them from
being “used” very often though… <o:p></o:p></SPAN></FONT></P>

<P class=MsoNormal><FONT color=#1f497d size=2 face=Calibri><SPAN
style="FONT-FAMILY: Calibri; COLOR: #1f497d; FONT-SIZE: 11pt">If you have a lot
of large equipment; CT’s, MRI’s, etc. then you’ll be closer to the 35%. If you
have a small clinic or medical office building that shares equipment between
locations, then you’ll be closer to 20%. <o:p></o:p></SPAN></FONT></P>

<P class=MsoNormal><FONT color=#1f497d size=2 face=Calibri><SPAN
style="FONT-FAMILY: Calibri; COLOR: #1f497d; FONT-SIZE: 11pt">Another
consideration is that your large equipment might be water cooled. If that’s the
case, you should put about 10-15% of the electric load in the space, and then
85-90% of the load as an external load similar to exterior lights. Make sure to
put an equivalent cooling load on you chilled water loop as a process load.

style="FONT-SIZE: 13.5pt">Hi Chen,<BR> I don't do much medical work or
LEED but the medical equipment should be modelled like a process load and have
it's own schedule you can manipulate. 60% sounds like a lot. With
it's own schedule you can change it to reflect its actual loads and locations in
the building. Process loads, like industrial loads don't effect
LEED. But they do effect the sizing of your HVAC equipment. So you
do have to model them realistically. You could put them on their own sub
meter as well. This might make separating from the LEED parts of your
project simpler. LEED or not, your building has to work well. That
is your primary focus. 60% is a big effect, make sure it is realistic and
make sure your systems can handle it.<BR>Bruce Easterbrook P.Eng.<BR>Abode

Care model and have a question about the electric of medical
equipments. After I modeled the equipments, the electric consumption of Misc.
Equip. is about 60% of total electric but the medical equipments are not
used very frequently. Do I have to add the medical equipments to the
model or where can I plan a schedule for the medical equipments? Did
anyone have the experience of modeling a LEED Health Care model? It's my first
time building a Health Care model, is there anything I need to look
over ? Any suggestion will be
