Online Thermal Comfort Compliance Tool Included in New ASHRAE User's Manual

ATLANTA – A new User’s Manual for ASHRAE’s thermal comfort standard provides an overview for new users while also including more detailed information for those more familiar with its requirements.

The User’s Manual, based on ANSI/ASHRAE Standard 55-2013, Thermal Environmental Conditions for Human Occupancy, provides detailed information on the requirements of the standard. It includes tables, illustrations and examples to aid users in the design, commissioning, and measuring and rating of thermal comfort in buildings.

The manual includes a free online thermal comfort tool that can be used as the official tool for showing compliance with Standard 55-2013 along with all of the published addenda. This online tool is available only to those who purchase the User’s Manual and can be accessed from any internet connected device. The web-based CBE/ASHRAE Thermal Comfort Tool was developed by the Center for the Built Environment at the University of California Berkeley.

“For a new user of Standard 55, the manual provides a great overview of what it takes to make a space thermally comfortable for the occupants,” Abhijeet Pande, chair of the Standard 55 committee, said. “This includes descriptions of how to account for the environmental, occupant and local factors that impact comfort. For an experienced user of Standard 55, the manual provides insights into requirements that are sometimes hard to understand in the standard. The User’s Manual provides examples of calculations that will help even the most experienced user who may struggle with figuring out where and how to get an input needed for thermal comfort calculations.”

The manual also includes:

• Information on the intent and application of Standard 55

• Guidance on applying the principles of acceptable thermal comfort and effective thermal control
