Chapter 14, Climatic Design Information, from the 2013 ASHRAE Handbook—Fundamentals

Worldwide Climate Data for HVAC Calculations

Includes climatic design information tables (from ASHRAE Research Project RP-1613) for 6,443 locations in the United States, Canada, and around the world—information used for design, sizing, distribution, installation, and marketing of HVAC and dehumidification equipment, as well as for other energy-related processes in residential, agricultural, commercial, and industrial applications.

Tables, included as a .zip file with the purchase of the chapter (.pdf), include dry-bulb, wet-bulb, and dew-point temperatures; wind speed with direction at various frequencies of occurrence; monthly degree-days to various bases; precipitation; and parameters to calculate clear-sky irradiance. Information includes monthly and annual percentiles, to provide seasonally representative combinations of temperature, humidity, and solar conditions.

Weather Data Viewer, Version 5.0

This DVD provides comprehensive climate data for the 6,443 locations listed in the 2013 ASHRAE Handbook—Fundamentals.

Files format: XLS

With Weather Data Viewer 5.0, users can display the tables in numeric form or plot the frequency distribution, cumulative distribution, and mean coincident functions. Also available are joint frequency matrices of dry-bulb temperature and time of day (also known as temperature bin data). The data can also be extracted into text format for batch processing using the included tblxpand utility.

Standard 169-2013, Climatic Data for Building Design Standards


ANSI/ASHRAE Standard 169-2013, Climatic Data for Building Design Standards, serves as a comprehensive source of climate data for those involved in building design, and provides a variety of climatic information for designing, planning, and sizing building energy systems and equipment.

Standard 169 is accompanied by online supporting files for climatic data and design conditions, as well as tables and figures. Data and tables have been completely revised for the 2013 edition.

The standard includes climate zone maps and data for the entire world. An additional "Extremely Hot" Climate Zone 0 with humid (0A) and dry (0B) zones has been added, and the standard includes climatic data for 5564 locations throughout the world (from ASHRAE Research Project RP-1453, as published in the 2009 ASHRAE Handbook--Fundamentals).

The standard provides dry-bulb, dew-point and wet-bulb temperatures; enthalpy; humidity ration; wind conditions; solar irradiation; latitude; longitude; and elevation for locations worldwide. Standard 169 also includes statistical data, such as mean temperatures; daily ranges; degree hours; and seasonal percentages within ranges of temperatures.
