Repository of free climate data for building performance simulation

From the Creators of the EPW


February 2019 - New Simulation Climate Data set (1791 files) for the following countries: China, Hong Kong, Macau, Japan, North Korea, South Korea, and Taiwan.

February 2019 - New Simulation Climate Data set (3683 files) for the following countries: Russia (both Europe and Asia), Asia: Armenia, Azerbaijan, Georgia, Kazakhstan, Kyrgyzstan, Mongolia, Tajikistan, Turkmenistan, Uzbekistan, Europe: Albania, Belarus, Bosnia and Herzegovina, Bulgaria, Croatia, Moldova, Montenegro, North Macedonia (FYRO Macedonia), Romania, Serbia, Slovenia, and Ukraine. We were helped (tremendously) with the Russian names by Sergey Zhukovskiy.  Any mistakes in any of the countries are ours, of course.

November 2018 - New Simulation Climate Data Set for "Middle East" (499) - Countries: United Arab Emirates, Bahrain, Iran, Iraq, Oman, Qatar, Saudi Arabia, Yemen, Israel, Jordan, Palestine, Syrian Arab Republic.  This in addition to the earlier posting for Kuwait.

October 2018 - New Simulation Climate Data Set for Africa (1525), South Asia (878), Western Asia-Kuwait (47), Southwest Pacific/Australasia (1953), portions of Europe (1352), and updated Antarctica (172)

July 2018 - 22 Korean (South Korea) climate files are available - from PHIKO - Passive House Institute Korea

Apr 2018 - New Simulation Climate Data Set for Mexico, Caribbean, Central and South America and Antarctica Available

A new simulation climate data set (TMYx) is now available for locations in Mexico, Caribbean, Central, South America and Antarctica, derived from the ISD (US NOAA's Integrated Surface Database) with hourly data through 2017. TMYxs for more than 1600 locations in the Americas are available. There may be two TMYxs for a location, e.g., MEX_MEX_Cuidad.Mexico-Juarez.Intl.AP.766793_TMYx, and MEX_MEX_Cuidad.Mexico-Juarez.Intl.AP.766793_TMYx.2003-2017. In these cases, there's a TMY for the entire period of record and a second TMY for the most recent 15 years (2003-2017). Not all locations have recent data.
