Climate.OneBuilding.org is pleased to announce that we have updated our TMYx weather data set for building simulation with source data through 2018. More than 13,500 locations are available worldwide. For locations in the USA, Canada, Mexico, Central and much of South America, solar data from NSRDB PSM V3 (https://nsrdb.nrel.gov/) are included.
TMYx are derived from the ISD (US NOAA's Integrated Surface Database) with hourly data through 2018 using the TMY2/ISO ISO 15927-4:2005 methodologies. These TMYx include access to more data within the source ISD, improving their consistency and quality. More details on the numbers of locations by WMO region are shown below.
Climate.OneBuilding.org now provides a worldwide climate TMYx data for building simulation at no cost for more than 13,500 locations and another 3,200 from other data sources worldwide. All data have been through extensive quality checking to identify and correct data errors and out of normal range values where appropriate.
Each climate location .zip on Climate.OneBuilding.org contains: EPW (EnergyPlus weather format), CLM (ESP-r weather format), and WEA (Daysim weather format) along with DDY (ASHRAE design conditions in EnergyPlus format), RAIN (hourly precipitation in mm, where available), and STAT (expanded EnergyPlus weather statistics).
