Description

Energy standards and codes, including ASHRAE/IES Standard 90.1 and ANSI/ASHRAE Standard 90.2, have used cooling degree-day (CDD) and heating degree-day (HDD) values, and representative weather files, in the development and specification of criteria. Since the selection of the previous CDD and HDD values and representative weather files in 2002, climate data has become available for a more-recent period of record and for a more-extensive set of U.S., Canadian, and other international locations. The CDD and HDD values for individual locations and the representative weather files for those locations have changed, in some cases, markedly. Consequently, it was necessary to update the CDD and HDDvalues and the representative weather files being used for the development and specification of criteria. This is the second paper in a two-paper series. The first paper explains how the CDD and HDD baseline values were updated and provided those values for the various climate zones. This second paper explains the process used to select representative weather files for the various climate zones, including the use of the degree-day-radius metric and minimum population thresholds. This paper lists three sets of representative weather files: global, U.S., and Canadian.
