Weather Files for
SkyCalc 3.0®
The SkyCalc30 download comes with 16
California Climate Zone weather files. Additionally, weather files for
33 US cities can also be downloaded from this webpage. To use SkyCalc3.0®
for any other location, a weather file needs to be generated. This can
be done using the SkyCalc Weather File Generator utility in eQuest
3.61b (or higher). eQuest is available as a free downloaded
from the DOE2 website. A SkyCalc3.0®
weather file (.wea3) can now be generated for any location in the world,
as long as a DOE2 compatible weather file (.bin) is available for that
location.
To generate a SkyCalc 3.0® weather
file:
Step1: Start up eQuest
Step2: On the Startup Options
Screen, select "Generate SkyCalc Weather File"
Step3: In the
SkyCalc Weather file Generator Window, select the Coverage, Region and
City for the location of which you want the SkyCalc weather file.
Step4: The options for Energy Code
and Climate Zone are selected on their own. Review these options and
modify them if needed.
Step5 (Optional): Match the Roof
Type and Roof U-factor closest to your project in SkyCalc for which you
intent to use this weather file. This step is optional and need only
be changed from default if the intended project is known. Matching
the roof type to your project increases SkyCalc's accuracy in thermal
calculations. Roof U-factor may be modified within SkyCalc after a
weather file has been created under Optional Inputs Tab (Row 29).
Step6: Click the Generate
Weather File button to create the SkyCalc 3.0®
weather file for your location which gets saved in the location
indicated under SkyCalc Weather File to be Generated.
