IWEC

The International Weather for Energy Calculation (IWEC), developed by ASHRAE to represent typical weather data for building energy analysis for 227 locations outside the United States and Canada. This weather data is derived from up to 18 years of DATSAV3 hourly weather data originally archived at the National Climatic Data Center. The weather data is supplemented by solar radiations estimated on an hourly basis from earth-sun geometry and hourly weather elements, particularly cloud amount information.
