Just received an email about a new tool that may be helpful for teams pursuing this credit:

The Center for the Built Environment has developed a web-based thermal comfort tool, which is now available for use: http://cbe.berkeley.edu/comforttool/. This free online tool is useful for performing and visualizing comfort calculations according to ASHRAE Standard 55-2010. The tool has been validated against the official ASHRAE Thermal Comfort tool. The tool could be used for design, research and teaching. The tool works in Firefox, Chrome and Safari. Internet Explorer is not supported.
