Chris - Sure, go right ahead and write a joint article for CIBSE and
ASHRAE.<br>
<br>
I know ASHRAE is working on interviewing those with a long-time
perspective (old-timers) to document early ASHRAE work.<br>
Jeff H - anything related to weather data happening in the history
effort? Maybe some members of the weather data TC would contribute.<br>
<br>
Linda - Does the forward of Engineering Weather Data have any
mention of the motivation for that data? Is that where the concept
of using 99% etc. was first used?<br>
<br>
Anyone out there have a copy of the Fluor Products publication? It
was cited as the source of the US design data in the 1972 HOF.<br>
Evaluated Weather Data For Cooling Equipment Design, Addendum No. 1,
Summer and Winter Data (Fluor Products Company, Santa Rosa, Calif.,
1964).<br>

<font size="3">I have a copy of the Engineering Weather Data
document (1978
version). (Thanks, Bob H). <br>
<br>
And many other historical "weather data" documents though not
sure how many discuss heating/cooling design data.<br>

You know what Michael. I
think you have the makings of an ASHRAE journal atricle! I
want to do
something similar for CIBSE. I'd love to use your findings. <br>

<dd>I haven't seen a reply yet to this, so here goes . . .<br>
<br>
</dd>
<dd>The oldest ASHRAE handbook on my shelf is a 1972 HOF
(thanks Bob
H.!). Chapter 33 is Weather Data and Design Conditions. The
reference
list includes these two primary sources:<br>
<br>
</dd>
<dd>Evaluated Weather Data For Cooling Equipment Design,
Addendum No. 1,
Summer and Winter Data (Fluor Products Company, Santa Rosa,
Calif.,
1964).<br>
</dd>
<dd>and<br>
</dd>
<dd>Engineering Weather Data (Army, Navy, and Air Force Manual
TM 5-785,
1963).<br>
<br>
</dd>
<dd>You can buy a copy of the 1958 edition of Evaluated
Weather Data on
amazon<br>
</dd>

<br>
<br>
</dd>
<dd>I bet someone out there has a copy of the Engineering
Weather Data
manual on a shelf. Some quick searching leads to this later
online
version.<br>
</dd>

<br>
</dd>
<dd>which says:<br>
<br>
</dd>
<dd>"The Engineering Weather Data (EWD) and other products
were
developed by the Air Force Combat Climatology Center
(AFCCC). Data is
provided for approximately 800 stations worldwide. Intended
to support
design and construction of DOD facilities, the format is
slanted toward
professional engineers, but could have numerous other uses.
"<br>
<br>
</dd>
<dd>Searching AFCCC leads here to a fascinating history.<br>
</dd>
<dd><a

moz-do-not-send="true">
https://www.airweaassn.org/Library/afwa/history.html</a><br>
<br>
</dd>
<dd>"The mission of AFCCC is one of military applied
climatology. We
collect, maintain, and apply worldwide weather data,
creating
climatological products to strengthen the combat capability
of America's
warfighters. AFCCC's support to America's warfighters has a
long
history."<br>
<br>
</dd>
<dd>And a fitting excerpt on the 75th anniversary of D-Day:<br>
<br>
</dd>
<dd>"There was probably no WWII operation, major or minor,
that did
not include climatological input. The planning for every
landing,
mission, and offensive, including the D-Day invasion in 1944
and the
atomic bombing of Japan, required extensive climatological
preparation
and analyses."<br>
<br>
</dd>
<dd>So, Chris, your impression appears correct. Weather data
statistics
were motivated by military requirements (for better or
worse), and
marketing cooling equipment.<br>
<br>
</dd>
<dd>Mike<br>
<br>
</dd>
<dd>p.s. The pages from the 1972 HOF are included in a
digitized NBSLD
manual (one of the great mother programs of building
simulation), pdf p.
287ff.<br>

<dd>Does anybody have any interesting background on the
sources of (and
motivations for calculating) the outdoor design
conditions now available
in ASHRAE HOF?<br>
<br>
</dd>
<dd>My impression is that it was possibly derived for the
purposes of
keeping B52's and allied v-bombers ready for action at a
