Ever since I started doing building energy simulations in the early
1980's, I have always relied upon NREL's TMY weather files for US
locations. Over the years, NREL has led the way in improving the data
quality as well as coverage of weather files. Before the TMY2s, how
many of us thought that weather files should be self-describing, and
before the TMY3s, how many thought it was possible to have TMY files for
over 1,000 US locations?
Therefore, when I was contacted recently by Dr. Manajit Sengupta of NREL
to provide a letter of support for their proposal to DOE on continued
funding of their work on solar radiation, I said of course, but then
suggested that someone should point out to DOE Solar that the whole
building energy community has been heavily reliant on NREL's weather data.
After discussions with several organizations in which I'm involved, I've
concluded the best way to convey this message is to provide NREL a
letter of support signed by individuals, rather than in the name of any
organization. I have now written such an Open Letter that I am posting
on bulletin boards such as this one (see following and also here). If
you wish to add your name in support of this Open Letter, please go to
http://weather.whiteboxtechnologies.com/support-NREL . I will be
accepting names through Monday, after which I will close the sign-up
list and send the letter to NREL.
I want to be clear that this is an individual effort, and its appearance
on this bulletin board does not imply any endorsement by the bulletin
board, nor of the organizations with which any of the signatories are
affiliated.

Re: Letter of Support for NREL's proposal to SunShot
National Laboratory Multiyear Partnership
Dear Dr. Sengupta,
We the undersigned wish to express our support to NREL's research
proposal titled "Solar Resource Calibration, Measurement and Dissemination".
As engineers and architects dedicated to the design and operation of
energy efficient buildings, andas researchers and consultants in the
field of building energy simulations, we've relied heavily on the
meteorological data that has been developed by NREL going back to the
1970?s, including the various versions ofthe Typical Meteorological Year
(TMY) weather files and the National Solar Radiation Data Base (NSRDB),
as well as other climatological data summaries. We especially look
forward to seeing the outcome several aspect of your proposal pertaining
to the following areas:
?Maintenance and upgrading of the Renewable Resource Data Center (RReDC)
?Maintenance and upgrading of the National Solar Radiation Data Base
(NSRDB), in particular the new datasets using satellite based models
providing accurate grid-based solar data for any location in the United
States (as well as international locations if possible).
?Updated and expanded coverage of TMY data sets incorporating the
above-mentioned solar radiation data.
?Continuing your research work that is crucial to new ASHRAE standards
in climate zone definitions and energy efficiency standards.
?We perceive high value in NREL's updating of its best practice handbook
on solarresources for solar energy application as a participant in IEA
Task 46.
We believe that continued work by NREL in this proposal is unique and
extremely beneficial to the work that we undertake todesign, construct,
and operatemore energy-efficient buildings, and improve our ability to
analyze building energy performance. Furthermore, the proposed work also
supports other major efforts being undertaken in the setting of building
energy performance standards, rating systems, and incentive programs by
other organizations such as DOE, ASHRAE, or various utility companies.
Sincerely,
[please give your name, affiliations, and e-mail address]note thatthe
affiliation s are purely for identification, and do not imply their
endorsement of this letter, and that e-mail addresses are for my record
keeping and will not appear in the letter of support.
