color:#1F497D'>Way back in the email chain, somebody said that what they did in
energy modeling had no effect on the construction drawings. That is a
realistic result for some projects, but unfortunate. I share the
frustration because I have worked on projects like that in the past. However,
if we energy modelers are doing our jobs, we should be pushing the designers,
and giving them feedback early on in the design process. But we have to
step up and do that. We can’t be a mouse and cannot just complain
about the architect and engineering design team members not paying attention to
the energy. Go educate them, & insert yourself in the design process.
Give them the feedback that Karen has described. Measure your success not
by how many LEED points the project earns, but by the fact that you helped the
design team change something about the building so that it is more efficient in
the real world (i.e. better wall insulation, better glass selection, better
light fixtures, higher efficiency HVAC equipment, etc.). I like how
somebody put it earlier in that energy modeling is for making decisions.
If you helped the design team make some decisions, consider your effort a success.
If your energy modeling resulted in nothing different in the construction documents,
figure out why and fast because you are not adding value to the design process,
which could be detrimental to your employment status. My personal opinion
is that I do not think an energy modeling profession will survive solely to estimate
LEED point for completed designs. If that is all we are doing, I think
the building owners will figure out a way to eliminate us and our corresponding
fees.<o:p></o:p></span></p>

differently than our energy models suggest. If you really care about
buildings using less energy, focus more on going into real buildings and
helping the operators and owners figure out the best way to operate them to
reduce energy. This gets into the M&V area, which I think all energy
modelers should be focused on going forward because it can add real value.
To that end, I will leave the group with one final bit of advice. Check

the Pacific Energy Center of PG&E.<o:p></o:p></span></p>

<p class=MsoNormal>One of my favorite approaches when things aren't designed
yet is to make a responsible assumption and use it in the model. With the
model results, my clients get a list of assumptions and inputs. This way
you can use the model to push the designers to create a responsible
design. The lighting designer hasn't finished designing yet? OK, enter
0.6 w/sf in your model push them to get their power density down while still
providing enough light! You can do the same with the building envelope,
mechanical systems, etc. If things are not finished, this also opens the
opportunity for you to get involved and help the design team create the design.
Show them the difference with model results between x and y. Show
them how good their building can be, if they want it to. This does mean
that the model has to be re-worked when it's time to submit LEED documentation
to reflect what is actually provided, but it's a small price to pay.<o:p></o:p></p>

<p class=MsoNormal>As the one who started this post, I must say I have learned
a lot.<br>
<br>
Thank you very much.<br>
<br>
What I have learned.<br>
<br>
1. I have been misusing energy modeling. I have been trying to use energy<br>
modeling for the sole purpose of earning LEED points.<br>
<br>
2. I use it late in the design. Late in the design I have found it easier
to<br>
tweak my model instead of my design. (in order to get the desired number of<br>
points)<br>
(I do have integrity, so it kills me to
"game" the system. But with<br>
so few rules it wasn't hard to rationalize inputs. I go home not feeling<br>
proud.)<br>
<br>
3. When the goal is a realistic energy modeling, a very good model can be<br>
created. When you are simply trying to reach compliance with some code,
the<br>
system can be gamed. This misuse and gaming of energy modeling is a waste of<br>
time, but this is the users (MY) fault.<br>
<br>
4. I need to get the other departments to realize that this isn't MY<br>
(mechanical engineer) energy model, but OUR energy model. (I'm trying to
get<br>
my model done and the electrical engineer still doesn't have his light loads<br>
and the Architect hasn't have a final roof design.)<br>
<br>
I'm like a monkey hammering with a wrench. The frustration was a<br>
misunderstanding of the tool.<br>
<br>
I hope I can get the other departments on-board and maybe start using the<br>
model as a design tool as it was intended.<br>
To those who are being asked to misuse modeling, it is rough.<br>
<br>
Once again, my frustration and stress with energy modeling was growing to the<br>
point it disturbed my sleep. Having this discussion helped. The
most<br>
helpful was all the responses I received about the benefits of the proper use<br>
of energy modeling, and empathy from others who know the pain of trying to<br>
create a model just to earn points.<br>
<br>
<br>
Thank you all,<br>
<br>
John Eurek<br>
