John, you army guy you...<br><br>I suggest that you embrace the art part and get good at the science. Your model will be just as good as your input. Whats that old saw? When you point the finger you have 3 others pointing back at you. While some modeling tools might be close to beta and hard to use, eQUEST isn't one of them. Each new version has bugs, but those are relatively few and are fixed quickly. You use energy modeling to predict the energy use and energy cost of a baseline and proposed buildings. Here in Oregon we actually do follow-up and make sure the predicted came close to the actual. We call it model verification. I would recommend that you spend more time learning the art, gathering the info, creating an actual weather file if the typical one's aren't good enough for you, and very carefully inputting the data into your modeling tool of choice. I'd be happy to offer you peer review services if you ever want to make sure your work is accurate.<br>

<br>
"Energy programs are external to the design process. The results are not used<br>
to generate construction drawings." This may be my #1 beef with energy<br>
modeling. What is the purpose?<br>
<br>
If you say, to save energy... It does not.<br>
<br>
I think of an artist who "wants" a glass box building. Then some intelligent<br>
people come along and explain that this design would waste energy. They<br>
convince him to have a smaller building with less glass. The change of design<br>
just saved a lot of energy..... Is this counted in the model? No.<br>
<br>
Why do we compare our buildings to themselves? I can design a turd and<br>
polish it to LEED standards. Where are the points for having a well designed<br>
building over a poor design? The baseline should have 20% glass... Period.<br>
If I use 10% glass I am saving energy. Even better would be a set BTU/Ft^2,<br>
you can do whatever you want as long as you meet the GPM like measure.<br>
<br>
As an engineer, I think about the numbers a lot. With LEED (energy modeling)<br>
if I have very efficient equipment I can show more energy savings by<br>
increasing windows. (The more my model uses the equipment, the more the<br>
efficiency difference shows up.) Then I can play all day with people<br>
schedules, infiltration, and ect. (All I have to do is justify what I used.)<br>
<br>
<br>
I have been involved in only 4 buildings which required energy modeling. We<br>
used innovative new technologies. 3 of the building could not be modeled due<br>
to limitations of the energy modeling programming. (One design used the<br>
rejected heat from the heat pump for reheat instead of going into the loop<br>
field. The other I used a split system and placed the condensing unit in the<br>
mechanical room for free heat.)<br>
<br>
Why are we being made to follow LEED (energy modeling) when the tools to do<br>
it are so primitive. Some (Blankety blank blank *$%#!&$) is having us go<br>
someplace where the technology is not reached. (Beta testing sucks)<br>
<br>
It feels like we are smoking unfiltered cigarettes, driving cars with no<br>
seatbelts, and painting with lead paint. People are going to look back at<br>
what we did and wonder how we couldn't see how dumb we were. I see it now.<br>
<br>
There has got to be a better way. A better way to show we are saving energy.<br>
The sooner we find it, the better.<br>
<br>
I found out last week that the person who's position I filled left because of<br>
LEED (energy modeling). I can't stand this obvious misguided attempt to save<br>
the world. As a person who values logic, every day suffering this ill-logic<br>
is torturous.<br>

P.S. Eric the energy model IS a statistical analysis. You assume a weather<br>
pattern, you assume a occupantacy schedule, you assume the activity level,<br>
you assume the amount the printer is used, the computer use, the number of<br>
times the elevator is used. You assume everything about a pretend senario<br>
and get a pretend number.<br>
<br>
There must be a better way to prove an energy efficient design. (My company<br>
usually works late hours, most people do, are we to model this? We could, we<br>
could not, we can make up so much.) We need a solid baseline... Not<br>
statistical models.<br>
<br>
P.P.S. It will all be smoke and mirrors until start looking at actual energy<br>
usage per square foot. If you want to use models to predict it, okay.<br>
Results matter, but not in LEED (energy modeling).<br>

Academia institutions and research centers tend to attach disproportionate<br>
amount of importance to energy modeling. Most them have not dealt with real<br>
buildings. Attached are my views on energy modeling.<br>
