1 1 Start-up Options Two primary choices Simulate a new or pre-existing building model Multiple pages of inputs Create a weather file for the SkyCalc skylighting spreadsheet One page of inputs

2 2 Generating weather files for SkyCalc3 SkyCalc3 available to download at Select climate file, energy code, and roof U-factor to generate a SkyCalc Weather file

3 3 Generating weather files for SkyCalc3 Building Location – Coverage Select the weather file set. There are three choices for this input: "California/Title24" limits the weather file choices to the sixteen California climate zones "All eQUEST Locations“ provides U.S.-wide weather file choices "User Selected" allows the user to browse his/her machine/network for any standard DOE-2 weather file

4 4 Generating weather files for SkyCalc3 Building Location – Region/City Select the weather region and city. Region lists the sixteen California climate zones or the 50 U.S. states, plus Canada, the Pacific Islands, Puerto Rico, and the Virgin Islands :

5 5 Generating weather files for SkyCalc3 Energy Code Select the Compliance code for the location California Title24 - provides climate zone choices of sixteen California climate zones. ASHRAE provides climate zone choices of eight ASHRAE 90.1 climate zones

6 6 Generating weather files for SkyCalc3 Climate Zone Select the Climate zone for the energy code. This input is used to calculate the default roof U- factor. The default selection for the California Title-24 energy code is based on the Region selected by the user and the default ASHRAE climate zone is selected based on a mapping of city (selected by the user) to HDD and CDD values

7 7 Generating weather files for SkyCalc3 Roof Type Select the type of roof. Displayed only if Energy Code = “ASHRAE ”. Choose from one of the three roof types, or specify a custom U-factor

8 8 Generating weather files for SkyCalc3 Roof U-factor Input the roof U-factor. A default U-factor is provided based on previous inputs. User may change the Roof U- factor here. The maximum allowed U-factor as per the selected energy code, climate zone and roof type, is reported on the side for reference. Note: Roof U-factor can also be changed in SkyCalc, however choosing the correct U-factor at the creation of the weather file will ensure more accuracy.
