The American Society of Heating, Refrigerating and Air-Conditioning Engineers have updated its Standard No. 169, “Climatic Data for Building Design Standards.”

Dru Crawley, chairman of the standard-writing committee, said all the data and tables included in the former version of the standard were completely replaced using the results from a society research project.

 “With this major revision, Standard 169 now includes climate zone maps for the entire world, as opposed to the 2006 standard which only included a U.S. climate zone map,” Crawley said. “This allows users outside the U.S. to more easily determine which climate zone their location is in.”

The revised standard now includes climatic data for 5,564 locations throughout the world and features statistical data including mean temperatures; daily ranges; degree hours; and seasonal percentages within ranges of temperatures.

The standard also covers dry- and wet-bulb temperatures; dew point; enthalpy; humidity ration; wind conditions; solar irradiation; latitude; longitude; and elevation for locations worldwide.
