This chapter and the accompanying data summaries in PDFformat provide the climatic design information for 9237 locations in the UnitedStates, Canada, and around the world. This is an increase of 1119 stations fromthe 2017 ASHRAE Handbook—Fundamentals. As in previous editions, thelarge number of stations made printing the whole tables impractical. Consequently,the complete table of design conditions for only an “example city” appears inthis printed chapter to illustrate the table format. However, a subset of thetable elements most often used is presented in the Appendix at the end of thischapter for selected stations representing major urban centers in the UnitedStates, Canada, and around the world. The complete data tables for all 9237stations are included with both the PDF version of this chapter and the Handbook Online version.
