Standard 169 is a comprehensive source for a variety of climatic information used in the design, planning, and sizing of buildings\u2019 energy systems and equipment. The data presented in the 2020 edition are compiled from the 2017 ASHRAE Handbook\u2014Fundamentals, Chapter 14, \u201cClimatic Design Information,\u201d and from ASHRAE RP-1699, \u201cUpdating the ASHRAE Climatic Data for Design and Standards.\u201d Data and tables have been completely revised and updated from the 2013 edition. The standard now also includes weather and shielding factor (WSF) required by Standard 62.2-2016, as well as data for 8118 locations throughout the world, an increase of 2554.<\/p>\n

Annual climatic design conditions are contained in the first three sections following the top part of the table. They contain information as shown in the following subsections. <\/td>\n<\/tr>\n | ||||||
| 8<\/td>\n | A2. Monthly Climatic Design Conditions A2.1 Temperatures, Degree-Days, Degree-Hours, Wind, and Precipitation A2.2 Monthly Design Dry-Bulb, Wet-Bulb, and Mean Coincident Temperatures. These values are derived from the same analysis that results in the annual design conditions. The monthly summaries are useful when seasonal variations in solar geometry and in… <\/td>\n<\/tr>\n | ||||||
| 9<\/td>\n | A2.3 Mean Daily Temperature Range. These values are useful in calculating daily dry- and wet-bulb temperature profiles. Three kinds of profiles are defined: A2.4 Clear-Sky Solar Irradiance. Clear-sky irradiance parameters are useful in calculating solar-related air-conditioning loads for any time of any day of the year. Parameters are provided for the 21st day of each month. The 21st of the month is usua… A2.5 All-Sky Solar Radiation. All-sky solar radiation parameters are useful for evaluating the potential of solar technologies (e.g., solar heating, photovoltaics), which are valuable in the design of net zero energy buildings. Parameters listed in t… A2.6 Climate Filenames and Order. Tables A-3, A-5, and A-6 list the 8118 stations alphabetically for United States, Canada, and other locations, respectively. Climatic design conditions for each location in both I-P and SI units are located online at… A3. Climate Zone Definitions <\/td>\n<\/tr>\n | ||||||
