Summary: The embedded Google map feature helps you find the closest (TMY) weather station when your location is close to a state/province or national border and the closest station is actually in a different state/province/country. These are the same weather stations that are used in the ASHRAE 62.2-2013 and 2016 tools, for example. Additionally, the tool’s interactive table and chart help you explore the Typical Meteorological Year (TMY) data for each of 1,100 weather stations in North America. This hourly data is the foundation for most building energy simulation software. See Tool Guide. Click on any input or result label for help.
