<br>
Your first statement is not quite correct. The California Energy
Commission had commissioned in 2009 the creation of a new set of
standard weather files to replace the pre-existing 16 CZXXRV2
weather files, for which I was the contractor. This work, which
was finished in December 2011, resulted in a set of 86 CZ2010
weather files and are available for public download on my company
Web site at <a class="moz-txt-link-freetext" href="http://weather.whiteboxtechnologies.com">http://weather.whiteboxtechnologies.com</a>, click on
CZ2010 (all files contain the same weather file in three formats
- archival *.TM2, *.EPW, and *.BINM).<br>
<br>
The California Energy Commission has yet to decide whether to
allow the use of all 86 weather files in Title-24 calculations, or
to limit it to a subset of 16, i.e., one standard file per Climate
Zone as before. From a technical point of view, I strongly
support the former position, although there are administrative
issues that need to be addressed to avoid creating confusion or
"gaming the system" that I hope the Commission will address in the
coming year.<br>
<br>
As an interim place-holder, I worked with the Commission staff and
consultants in late 2011 to assign representative locations out of
the 86 for each of the 16 Title-24 Climate Zones. This list was
shown at a Nov. 2011 workshop in Sacramento (see attached, full
PPT available on the Commission Web site - search for "Huang
Weather Data Presentation") and is probably the basis for what
you've heard about the CZ08 file changing from El Toro to
Fullerton.<br>
<br>
Although I am not violently opposed to such an interpretation, I
do wish to mention the following caveats:<br>
1) the pre-existing CZXXRV2 weather files were adjusted in the
early 1990's (that's the reason for the RV2 designation) to be
more representative of the climates within each Climate Zone;
therefore, it's incorrect to refer to any of them as being from a
specific location, i.e., CZ08RV2 != El Toro.<br>
2) the new CZ2010 weather files have not undergone any such
adjustment process (nor would I recommend so doing), and should be
regarded as "representative" rather than "average" weather files
for each Climate Zone, selected based primarily on population and
only secondarily on climate considerations.<br>
<br>
The last point I want to make is that the CZ2010 files are
different from the TMY3 weather files for the same stations in
many ways:<br>
1) uniform period of record (1996-2009) <br>
2) uniform typical months for all 86 stations<br>
3) solar radiation from remotely-sensed data, i.e.,
satellite-derived<br>
4) different software used to fill missing data <br>
<br>
So, to make a long story short, if you're concerned about the
Commission's change in standard weather data, please download the
new CZ2010 weather files at
