Why Should I download Climate Data Files from Climate.OneBuilding?
- Annual and monthly design conditions from Chapter 14, 2021 ASHRAE Handbook-Fundamentals
- Design conditions from another location in the 2021 Fundamentals substituted when none are available for that location
- Annual design conditions calculated from source weather data in absence of ASHRAE design conditions.
- Frequent updates as new weather data sets and design conditions are released
- Consistent, validated, specific location naming:
- USA_VA_Arlington-Reagan.Washington.National.AP or USA_VA_Sterling-Washington.Dulles.Intl.AP instead of Washington, DC
- Additionally, WMO (World Meterological Organization designation is included)
- Hourly precipitation in a separate file for direct use in simulations (where source data includes precipitation)
- Extensive quality checking to identify and correct data errors and out of normal range values where appropriate. All changes -- alternate design condition locations and corrections to data -- are documented on the web site for each data set.
