Katie, in order to convert weather files, you need to download the eQ_WthProc from the following location and follow the instructions on the website: http://doe2.com/index_wth.html

If you already have your epw file, then place it in the "SourceFiles" folder that will be created with this install. If you do not have an epw file, you can download one from here: http://apps1.eere.energy.gov/buildings/energyplus/cfm/weather_data.cfm

In the "Processor" directory, double click on eQ_WthProc.exe, click Run, you should then see the following:

In the EnergyPlus weather file box near the top, click the [cid:image003.png at 01CA9922.2D6A4F00]  and navigate to the SourceFiles folder and select the epw file you placed in there. Then click the big Convert button on the bottom left.

It will take a few seconds and then your dialogue box should look like this with writing in the bottom white area that says Formatted weather data successfully:

If you get an error saying "Invalid file name" or something like that, then you need to follow the directions on the first website I sent that talks about changing the .INI file. I did option 2 and opened up that INI file in a text editor, changed the path names,  and then it worked perfectly.

You new .bin file will be located under the EPW folder, I believe.

Hope this helps,

After reading through your directions, it seems you're going from a .BIN file to a .TXT file.  I need to MAKE a .BIN file from weather data (TMY2 or other).  Do you know how to do that?

Katy, as to you first question I am unable to answer, for the second part on

using the Converter I might be able to help



Once downloaded



- Navigate into the Util32 folder

- Put of copy of the tmy file you wish to convert in the Util32

- Right click on the MKAFT.BAT file

                -Edit

- Change  set doedir=  to the match  the file directory you are in (ex.

C:\documents and settings\my documents\ ....)

- Change  set weather.bin = (the file you wish to convert) ex.

MT_Gallatin_Field.bin

- Change  set weather.fmt = (the file you wish to convert) ex.

MT_Gallatin_Field.ft

- Save the file

- Double click MKAFT.BAT to run the program

- A .ft file will appear in the directory

- Rename as .txt (ignore warnings)



The first 3 lines are usually some junk, then the column headings from left

to right are



Month

Day

Hour

Twb

Tdb

Patmos

CLDAMT

ISNOW

IRain

Wind Direction

Humidity Ratio

Density

Enthalpy

Solar Radiation

Direct Solar Radiation

Cloud Type

Wind Speed



We have a Data base set up to import the data into the correct headings...



Hope this helps
