Software news New Global Simulation Climate Data Set from Climate.OneBuilding.Org In September 2019, Climate.OneBuilding.org completed a worldwide data set with more than 13,500 TMY (Typical Meteorological Years) locations for building performance simulation with data through 2018. In September 2021, the entire data set was updated with weather station meteorology data through 2020 and corresponding solar radiation from the ERA5 reanalysis data set (www.ecmwf.int/en/forecasts/datasets/reanalysis-datasets/era5). The ERA5 data, courtesy of Oikolab (https://oikolab.com/), provides a comprehensive, worldwide gridded solar radiation data set based on satellite data. With more than 1500 new locations (>10% increase), this brings the total to more than 15,000 locations. These TMYx are derived from hourly weather station meteorology data through 2020 in the ISD (US NOAA’s Integrated Surface Database) and ERA5 reanalysis gridded solar data using the TMY2/ISO ISO 15927-4:2005 methodologies. There may be two TMYx for a location, e.g., Washington Dulles Intl AP, VA, USA: USA_VA_Dulles-Washington. Dulles.Intl.AP.724030_TMYx and USA_VA_Dulles-Washington.Dulles.Intl.AP.724030_ TMYx.2006-2020. In these cases, there’s a TMY for the entire period of record and a second TMY for the most recent 15 years (2006-2020). Not all locations have recent data. With this update, Climate.OneBuilding.org now provides TMYx climate data at no cost for more than 15,000 locations worldwide and another 3,200 from other data sources. 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 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).
