<div>Thank you, Joe, for more underlying drama from the Lab. I never claimed to be an expert, but certainly hung with those who WERE expert. You being one. And God save DrawBdl !! Never knew my models came out so WEIRD !!</div><div><br></div><div>I think the California Energy Commission, the City of New York, and the Green Building movement have asked WAY too much of simulation !! It is a F...ing estimate, not an exact science !!</div><div><br></div><div>Hope you can actually retire someday, Joe. Modeling to me has become more of a chore.</div><div><br></div>

<p>I was at LBNL for 27 years! The Lab always gave me just enough
inducements to keep me from leaving, but never enough to feel
really secure. I'm sure other former or current LBL employees
know the feeling.<br clear="none">
</p>
<p>I notice John still uses the old acronym LBL, as is still
found in Lab's e-mail address @lbl.gov - some things are sacred.
I liked Bruce very much. He came from an industrial rather than a
scientific background, having worked at Carrier for many years. I
remember one time he decided to give a 3-day lecture series (1
hour lectures for 3 days, not a 3 day filibuster :-) ) about the
history of air-conditioning starting from the 1930's. I think
Bruce got offended when Art Rosenfeld commented, "oh, that's just
engineering!" (Art came from a nuclear physics background).
Bruce's nuts-and-bolts no-nonsense approach can be unnerving. I
remember doing research on the Urban Heat Island Effect and asked
Bruce for some prototypical building models. Bruce brushed off
the UHI as something that's inevitable nobody can do anything
about, and then asked me for an account number to charge his time
:-) which I thought was fair.<br clear="none">
</p>
<p>I feel said when I visit the Lab these days, because all the
seminal people who developed DOE-2 are now gone, including all
those mentioned by John below. The original team was really quite
skillful - Zulfi Cumali (who was always a consultant, not staff
at LBNL) for coming up with the overall program structure, Ender
Erdem for doebdl, the two Freds (Winkelmann and Buhl) for loads,
Jeff Hirsch for system, and me (:-)) for pestering them when
things didn't work! <br clear="none">
</p>
<p>A classic Ender answer was when I found that my function stopped
working with a new DOE-2 version. I asked Ender whether the Zone
pointers have been changed and Ender said no! A few moments
later he came to my room, said, "oh, there is 'some' change!" and
wrote the new pointer location on a slip of paper. Classic
understatement, equivalent to being somewhat pregnant.<br clear="none">

<div>I would like to remember the LBL staff in the good
old days, which i believe Joe was a member. My personal
patient mentor was Bruce Birdsall. I had the pleasure of
having dinner with him several times and staying at his
apartment when visiting LBL. His apartment was one of
the first victims of the oakland Hills fire (198 ??).</div>
<div><br clear="none">
</div>
<div>Also remember taking my first class in DOE-2 (1982)
from Fred Buhl and Jeff Hirsch. I must confess that
after the two days, I still had no idea how to perform
models in DOE-2. Fortunately, Bruce patiently saved the
day.</div>

<div dir="ltr">Me, again, just got done with a personal
chore.<br clear="none">
<br clear="none">
Now that we're attempting to make energy simulations
funny, I thought <br clear="none">
I'd share what I remember from my almost 40 years (:-o)
experience that <br clear="none">
struck me as amusing. These are true stories, not "fake
news" :-) ;-)<br clear="none">
<br clear="none">
1. We were sitting around the room at LBNL talking about
converting a <br clear="none">
Fortran program from VAX to Unix. The fellow sitting
next to me asked, <br clear="none">
"isn't that just changing the extension from *.for to
*.f ??<br clear="none">
<br clear="none">
2. A new hire at LBL told me that he went to a party
where someone asked <br clear="none">
him what work did he do? So, my colleague said, "I
simulate buildings <br clear="none">
on a computer". The other person replied, "oh, that's
easy. Buildings <br clear="none">
don't move!".<br clear="none">
<br clear="none">
3. I was working with the late Art Rosenfeld in the
early 80's writing a <br clear="none">
paper on building energy efficiency for Art to present
at the first <br clear="none">
international energy conference in China in 1982. Art
was writing what I <br clear="none">
thought was a naive' comment that building energy
efficiency will pay <br clear="none">
for itself by the savings in coal. I explained to Art
the intricacies <br clear="none">
of China's fuel pricing system. Art thought for a moment
and then <br clear="none">
changed the sentence from "We believe that..." to "We
are confident <br clear="none">
that...". Art then nudged me and said, "frequently
wrong, but always <br clear="none">
confident!". (I've collected lots of Art Rosenfeld
anecdotes over the <br clear="none">
years).<br clear="none">
<br clear="none">
4. I learned DOE-2 for the first time in a class at UC
Berkeley in <br clear="none">
1980, and had the assignment of modeling a small cabin
picked from <br clear="none">
Progressive Architecture, using an input file from a
previous student as <br clear="none">
an example. It all made sense, but I wondered why the
file had double <br clear="none">
periods at the end each sentence, which I thought was
redundant. So, I <br clear="none">
wrote my file with single dots! The computer then spat
out that the <br clear="none">
file had 109 errors! I would never make that mistake
again.<br clear="none">
<br clear="none">
5. I was at ASHRAE in the early 80's listening to Ed
Sowell make his <br clear="none">
presentation about ASHRAE Weighting Factors, with the
title something <br clear="none">
like, "32,000 weighting factors for different room
configurations". An <br clear="none">
acquaintance standing next to me whispered to me, "now
that's a really <br clear="none">
big building"!<br clear="none">
<br clear="none">
6. (last one). I was involved in a DOE project in the
late 80s to turn <br clear="none">
DOE-2 simulation results into a simplified tool for
estimating <br clear="none">
residential energy use (PEAR), working with an A/E firm
Steven Winter in <br clear="none">
New York. One time I was talking to Steven Winter staff
about some <br clear="none">
technical minutae just when the Loma Prieta Earthquake
struck (1989). <br clear="none">
It felt good in a way to hang on them saying, "I can't
talk now. There's <br clear="none">
an earthquake"! Standing outside in the parking lot
watching plumes of <br clear="none">
smoke arise in San Francisco across the Bay felt like
being in a movie.<br clear="none">
