color=#0000ff size=2>The responses generally told me what I expected to here,
that most simulation software was not to the point yet where people were
comfortable in using it for load calculation and system sizing, with the
exceptions of Trace700 and Carrier's HAP4 as some have

<DIV dir=ltr align=left><SPAN class=792541913-29012008><FONT face=Arial
color=#0000ff size=2>The following issues seemed to resonate strongest from the
responses as to why <EM><STRONG>not</STRONG></EM> to use software like DOE2 or
eQUEST for sizing equipment:</FONT></SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=792541913-29012008><FONT face=Arial
color=#0000ff size=2>1) Difficulty in setting up model (complicated, clumsy,
more susceptible to errors) and cumbersome organization of

<DIV dir=ltr align=left><SPAN class=792541913-29012008><FONT face=Arial
color=#0000ff size=2>2) Model zoning generally combines similar HVAC zones and
does not require detailed zoning usually required in load calculations
(simulation models too detailed and will take too long to
run)</FONT></SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=792541913-29012008><FONT face=Arial
color=#0000ff size=2>3) TMY weather data is generally not representative of

<DIV dir=ltr align=left><SPAN class=792541913-29012008><FONT face=Arial
color=#0000ff size=2>4) Schedules (occupant, lighting, equipment, etc.) for

are different</FONT></SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=792541913-29012008><FONT face=Arial

<DIV dir=ltr align=left><SPAN class=792541913-29012008><FONT face=Arial
color=#0000ff size=2>1) I agree that for novice (or even
many intermediate) users, you would be asking for trouble if relying upon
the results of a simulation model for sizing equipment. Though your chances of
success improve as you learn to check, and double check the output, and
interpret results.</FONT></SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=792541913-29012008><FONT face=Arial
color=#0000ff size=2>2) Getting into a hundred+ zones in a building could
be difficult to manage, but for a Core and Shell building with block loads
it should not be excessively burdensome</FONT></SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=792541913-29012008><FONT face=Arial
color=#0000ff size=2>3) eQUEST does allow for the creation of Design Day weather
conditions (directly adding to the .inp file is the only way I know how to do it
but there may be another way)</FONT></SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=792541913-29012008><FONT face=Arial
color=#0000ff size=2>4) eQUEST also allows for Cooling Design Day schedules and
Heating Design Day schedules (again by adding to .inp file)</FONT></SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=792541913-29012008><FONT face=Arial
color=#0000ff size=2>5) I too look forward to advances in the software that can
take the detail that goes into a model and gain more from it that just a few

<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">I would clarify two
things. First is that the load calculations are done, or should be done,
for the design condition, not the worst possible condition plus safety
factor. For cooling that normally means the ASHRAE 97-1/2% condition; for
heating, the 2-1/2% condition. Some programs list adjustments as safety
factors, but there is really a higher purpose. One is a morning warm-up
factor that allows night setback energy savings to be realistically
achievable. Similarly, a cool-down factor can be applied to the cooling
load and comes into play often on Monday morning when the system has been off
over the weekend and the building mass has gotten quite warm. If you can’t
cool it down, then you can’t save as much energy by letting it get or stay warm
for as long prior to occupancy. The warm-up and cool-down factors are
largely a function of the space mass (the greater the mass, the larger the
factor needed). There is also the possibility of either adding capacity
for future building or process load additions or designing for the ability to
add the capacity in the future. It is best to do that in a modular way the
does not penalize efficiency until the future load is
on-line.<o:p></o:p></SPAN></FONT></P>
<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial"><o:p> </o:p></SPAN></FONT></P>
<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">Second is that load
programs do have schedules for people, lighting, appliances, and power
equipment. It is proper to set those realistically for the highest
anticipated conditions, but not higher. If set higher, or at 100%, then
the result will have compounding additional capacity (safety factors multiplied
upon each other resulting in grossly over-sized systems). Heating is
traditionally treated differently in that internal loads are normally not left
on for the design condition. It is possible to turn off all lights and
internal gains during a heating requirement. Cooling is a little different
in that some loads are simply never all on at the same time. People move
throughout the building and they also come and go, so diversity factors are also
appropriate.<o:p></o:p></SPAN></FONT></P>
<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial"><o:p> </o:p></SPAN></FONT></P>
<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">I would expect, or at
least want, a program that does both load calculation and energy modeling to be
able to account for morning warm-up and cool-down (including after a power
outage) by sizing the systems to have sufficient reserve capacity to recover in
a reasonable period of time (and have that time adjustable). It would need
to consider building mass, and look at setback/setup differentials vs. recovery
time and reserve capacity.<o:p></o:p></SPAN></FONT></P>

<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Summer load calculations are done at
the worst summer design conditions (outdoor air temperature, outdoor humidity,
solar gain, etc.), and all of the internal gains are assumed to be on 100%

may not have 100% of the internal gains on during the peak summer conditions,

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Winter load calculations are done at
the worst winter design conditions (outdoor air temperature, nighttime, etc.),
and the internal gains are all assumed to be 0% (e.g., no people, no lights, no

<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Some load programs allow the user to
add a safety factor to the heating and cooling loads (not just the equipment
size). So the heating/cooling load in your zone is increased, therefore
your air supply cfm is increased, your AHU is increased in size, your plant
size is increased, etc.). I don't know how to do this
directly in any of the energy analysis programs that I
use.</SPAN></FONT><o:p></o:p></P>
<P class=MsoNormal><FONT face="Times New Roman" size=3><SPAN
style="FONT-SIZE: 12pt"> <o:p></o:p></SPAN></FONT></P>
<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Because of these and other
differences, I have found that energy modeling programs will give smaller
equipment sizes than do load programs. Engineers typically error on
the side of safety, and therefore they prefer to size equipment for the worst
possible scenarios as described above. When I was designing building
mechanical systems, I would never count on 25% of the lights being on at
night when it's -20 degrees F outside so that I could reduce my boiler
size. My loads program would give me a larger boiler, whereas my
energy modeling program would give me a boiler sized as if the lights will be
on. Also, the local TMY2 weather file that I use for energy modeling
doesn't even have -20 degrees F as an outdoor air temperature, and this is the
temperature that many engineers use to design their heating systems. M
loads programs allow the outdoor design conditions to be input
directly.</SPAN></FONT><o:p></o:p></P>

<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Load programs require much less
input than energy programs, and generally don't require any special knowledge,
art, or workarounds. Energy modeling programs require much more
input, require very specialized knowledge and experience, and always require
workarounds and creative inputs (art) to get the correct
results.</SPAN></FONT><o:p></o:p></P>

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">All that being said, Trane's Trace
700 program does an acceptable job of being both a loads program and an
energy analysis program, although it does have strengths and weaknesses in both
areas. In Trace, when running loads, you can disable the energy
related inputs. After you are satisfied that you have the correct loads,
then you can proceed to working on the energy parameters and inputs. You
can easily switch between running loads only and loads + energy at any
time.</SPAN></FONT><o:p></o:p></P>

experiences or precautions in using simulation models (particularly eQuest,
DOE2.1e, EnergyPlus) for load calculations? Any advantages/disadvantages,
tricks, or warnings in using these simulation models as opposed
to dedicated load calculation software like Elite's CHVAC? Any studies
comparing the two?</SPAN></FONT><o:p></o:p></P></DIV>
