Weather Data Viewer version 6.0 enables users to view the frequency tables and joint frequency matrices for all 8,118 stations provided in the 2017 ASHRAE Handbook-Fundamentals. Using Microsoft® Excel®, users can display the tables in numeric form or plot the frequency distribution, the cumulative distribution function, and the mean. B uilding energy simulations require weather data as an essential input. ASHRAE, in collaboration with White Box Technologies (WBT), now provides web access to ASHRAE's IWEC2 'typical year' weather files for 3,012 international locations outside of the US and Canada. IWEC2 weather files can be purchased individually, as sets by country. ASHRAE climatic design conditions station finder. ASHRAE CLIMATIC DESIGN CONDITIONS 2009/2013/2017. Jul 01, 2017 The Weather Data Viewer (WDView) DVD (ASHRAE 2017b) has been upgraded to version 6.0, containing data from all 8118 stations. Beyond access to all the printed climate elements, WDView contains the joint frequency distributions from which the elements are calculated, allowing calculations at other probabilities.
Climate Data Download Center
There are many different weather data formats available. EQUA currently offers a selection of climate files for IDA ICE, using the formats described below.
To download weather files, use the menu to the left.
Test Reference Year (TRY)
The TRY weather data are composed from measured data of representative months to form a whole representative year.
ASHRAE IWEC
The ASHRAE IWEC 1.1 database contains 'typical' weather files for 227 locations outside the USA and Canada. The International Weather for Energy Calculation (IWEC) files are derived from up to 18 years of DATSAV3 hourly weather data originally archived at the National Climatic Data Center.
ASHRAE IWEC 2
The ASHRAE IWEC 2 database contains 'typical' weather files for 3012 locations outside the United States and Canada. The files are derived from Integrated Surface Hourly (ISH) weather data originally archived at the National Climatic Data Center.
EnergyPlus Weather Data
Weather data for more than 2100 locations are now available in EnergyPlus weather format — 1042 locations in the USA, 71 locations in Canada, and more than 1000 locations in 100 other countries throughout the world. The weather data are arranged by World Meteorological Organization region and Country.
