Wow, has it been twenty years already?? It doesn't feel like it. I still remember a time
back then when there was an informal meeting about the future of building energy
simulation programs at the ACEEE Conference, probably in the late 80's or early 90's. Jeff
Haberl looked at me and said that the DOE-2 Group should have a? Home Page.? I looked back
at Jeff and asked, "what's a? 'home page'" ?

Yes, time flies like an arrow but fruit flies like bananas.

I began my modeling journey in the fall of 1994. I was given a rolling ruler, a tape measure and a clip board to audit a small commercial building. Having gathered the building information, I went back to the office and opened the DOE2 Basics, fired up the old 8086 DOS box and started typing. We were using Acrosoft DOE2.1e and Brief for the text editor. I still program my text editor to use the Brief keystroke short cuts. The 40 MB hard drive filled up pretty quickly. Upgrading cost $1 per MB ? a 350 MB hard drive cost $350.

I was very grateful when I discovered DrawBDL for debugging the geometry ? thanks to Joe!

Bill,

I wonder if there are any real buildings that look like
that? I can imagine a school maybe.

Thanks

Chris,

You're welcomed! The history behind DrawBDL was that I got tired of
drawing little sketches on paper to visualize what a model looked like,
and wrote a little program that read the coordinates and turned it into
an input file for a Unix-based sketching program at the Lab (TELLEGRAF).
I then showed it to a programmer friend who said he'd try turning it
into a PC program using Turbo Pascal. In 3 weeks time he had a working
prototype, but being a real computer programmer Jim said that we were
only half done.? So true that was!

One reason for the gaudy primary colors for the surfaces was that Jim
was concerned about what graphics processors people had on their PCs and
so stuck with 16-bit color. PCs were so limited in power then that when
I went to DOE in the early 90's and demo'd DrawBDL on somebody's PC
there, the drawing was so slow (blink ! another window! ) that I stopped
the demo to avoid losing the audience.

Those were the days.

Y?all don?t know me but I see you know each other well.

As an infrequent contributor but avid reader of the lists, I write to thank the list progenitors and all contributors for sharing your experience, knowledge, and humor! I?ve become a bit maudlin over the text mining graphs as I see the end of an era? whence cometh the phoenix?

I am a latecomer to DOE2. In the 1990s at ADL we used the DOE2 hourly load profiles for commercial buildings (I believe done at LBL by Joe, etal) in all kinds of building equipment studies for the DOE. Discovered the guis even later, VisualDOE in 2005, and finally eQuest in 2010. As I change my mind frequently and want to look at all the angles I am way too impatient for Open Studio and EnergyPlus. As far as modeling goes, dark roast (with a shot).

Cheers

BTW, Man-Fraction is why too high on these lists.

Melissa,

Wow, when you mentioned hourly load profiles for commercial buildings, that really brought
back to me memories from that time long ago!? For years, the work I did on load profiles
was funded by the Gas Research Institute in Chicago (now I think merged with GTI), exactly
for the purposes that you apparently used it for, i.e., as a convenient way for engineers
and manufacturers to evaluate their equipment without having to do building energy
modeling.? For a while, there was a slow but steady stream of people who were interested
in the load profiles, each of whom wanted some level of customization - like a heat pump
guy who didn't want a night setback, etc.? The realization struck me to make the building
prototypes as flexible as possible, since very few people wanted just to rerun the model
with no changes at all!??? So, I kept "macro-tizing" the building models so at the end, it
was just a collection of macros and include files that people can switch out.?? Then,
there was one consultant who came by my office to say he wanted to get the whole set of
hourly load profiles and asked if I could put it on the Web so he could download it (mind
you, this was in the 1980's).? I told him I thought that would be incredibly slow, but his
response was, eh, we'll just let the machine sit there for a night. Amazing how much data
are now transferred over the Web every single moment.

Thanks Jeff.

Here is a great database of school designs I've been looking
at for a recent project:

FYI...Jason's right about schools...

In the 2009 Dissertation by Piljae Im there's a summary of the most common types of school buildings...and some of the come pretty close to the odd looking building below...
