This paper describes a new climate classification for use in characterizing the performance of energy efficiency measures for buildings. The classification is designed for use in energy codes and standards, design guidelines, and building energy analyses. This is the second paper in a two-paper series. The first paper contains background on climate classification and describes the development process for the new classification. This second paper presents the zone definitions both descriptively and mathematically, describes related climatic materials that have been developed, such as maps, and provides a comparison of the new classification with existing classifications. Significant advantages of the new classification are highlighted.
