This download area also provides access to a wide variety of weather data that is compatible with eQUEST, DOE-2.x, PowerDOE and COMcheck-Plus. eQUEST will automatically download data from this area, except the non-us directory, when available. The pre-processed weather data available includes: CTMY (Canadian TMY, 12 locations, derived from Canadian Government data) CTMY2 (CTMY, updated 40 location version, derived from Canadian Government data) CZ2 (California Climate Zones Revision 2, 16 zones, 1992 supplied by the California Energy Commission) TMY (Typical Meteorological Year, 238 locations, derived from US NOAAs NCDC TMY datasets) TMY2 (Typical Meteorological Year version 2, 238 locations, derived from USDOEs NREL datasets) TRY (Test Reference Year, 60 locations, derived from US NOAAs NCDC datasets) WYEC (Weather Year For Energy Calculations, 51 ASHRAE locations, derived from US NOAAs NCDC data) WYEC2
(WYEC version 2, 51 ASHRAE locations, derived from US NOAAs NCDC datasets) Note on WYEC and WYEC2: these are not the ASHRAE files -get those from ASHRAE. NON-US (various ZIP
archives containing undocumented data for locations outside |

eQ_WthProc: Convert EnergyPlus EPW Files into eQUEST and
DOE-2 BIN Files
eQ_WthProc can convert
EnergyPlus (epw) files into eQUEST/DOE-2 (bin)
files. Download
the program archive into your eQUEST/Weather subdirectory; this can be done
by right clicking on the above link and selecting “save target
as” then navigating to your eQUEST installation directory and its
Weather sub-directory and selecting save. Then unzip the program archive into
your eQUEST weather directory retaining its directory structure. If your
eQUEST directory is not in the \Program Files\eQUEST 3-5 directory, or you
install the program in an alternate location, you have two alternatives for
correct program operation:
Sample epw source and bin/ft converted files are included to
illustrate program operation. epw files are placed into the
EPW/SourceFiles directory, then processed on the
“EPW Weather Files Conversion” tab by pressing the
“Convert” button after selecting the file in the
“EnergyPlus weather file” control. After conversion the resultant
bin files can be found in the EPW directory for convenient access by eQUEST. The
processor includes the ability to graphically review the
processed weather data. This is an important step in assuring the
quality of the weather data and should be done each time a weather file is
converted. After
file conversion, the hourly weather data is graphically viewed on the
“Review Converted Data” tab. If multiple files have been converted
during a program session, press the “List All Results”
button to populate the pick list with all converted weather
sites. The "View Detailed Chart" button brings up a more
detailed chart that allows for a thorough examination of the data,
including comparison of original and final data. Missing or out-of-range
data in the original file will be replaced with interpolated or previous-day
data. Use the left and right mouse buttons and drag the cursor to zoom
in and out of the hourly data. The
temporary data used for the graphics are deleted when the
program is closed, so only those sites converted during the current
session are available. If you want to save the graph data click on the
"Save CSV files" checkbox. You will find two files, one with
the original data used from the EPW file and one with the final data used to
create the BIN file. Be sure to copy or move these files to another
directory if you want to save them. The
processor includes the ability to have direct normal solar data
re-calculated. Some epw files contain questionable
direct normal solar values while having seemingly good horizontal solar
values; this problem can be diagnosed using the “Review Converted
Data” tab (described above) and noting direct normal values that often
or significantly exceed 1000. To correct problematic direct normal values
just check the “Calculate Solar Direct-Normal based
on Global Horizontal” check box on the “EPW Weather Files
Conversion” tab and re-convert the data. |

DOEWth: Convert NOAA/NCDC and Other Common Format Files
into eQUEST and DOE-2 BIN Files The DOE-2
processor that can convert a variety of standard formats, obtained from
NOAA/NCDC and other sources, into DOE-2 bin files. This utility can process
TMY2, WYEC2 CZ2 and other common formats but is a DOS box tool that does not
include a windows user interface. Download
the program archive onto your hard drive; this can be done by right clicking
on the above link and selecting “save target as” then navigating
to the top most directory and selecting save. Then unzip the program archive
onto the hard drive retaining its directory structure. A DOE22 directory will
be created with a util32 subdirectory containing a number of batch p[procedure to utilize the DOEWth processor. These are described in the Readme.txt file
in the util32 sub-directory, and include: v
LSTABIN-
used to list a DOE-2 bin file v
LSTATMY-
used to list a NOAA TMY format text file v
LSTATRY-
used to list a NOAA TRY format text file v
MKAFT- used
to create a text file (.ft format) from a bin file v
PKAFT- used
to create a bin file from a text file (.ft format) v
PKATPE- used
to process a NOAA text file into a DOE-2 bin file v
STAT - used
to create a weather file statistical summary of a bin file
