FOREWORD

Standard 169 provides a comprehensive source of climate data for those involved in building design. It has been established to provide a variety of climatic information used primarily for the design, planning, and sizing of buildings' energy systems and equipment. This standard is referenced in other standards, such as Standards 90.1, 90.2, and 189.1.

The data presented in this standard are compiled from the 2017 ASHRAE Handbook-Fundamentals, Chapter 14, "Climatic Design Information," and other data developed specifically for this standard from ASHRAE RP-1699, "Updating the ASHRAE Climatic Data for Design and Standards."

The data and tables have been completely revised and updated from Standard 169-2013. The standard now also includes the weather and shielding factor (WSF) required in Standard 62.2-2016. The standard includes data for 8118 locations throughout the world, an increase of 2554.

Where changes are shown in the text, new text is shown by underline and deleted text shown by. Due to the large increase in the number of locations covered in this station and the resulting changes, some tables are replaced in their entirety rather than using strikeout and underline, indicated by italics.
