Recently, multiple free-to-use online tools have been developed to help practitioners and researchers analyze thermal comfort. This presentation covers two such tools: one is the official ASHRAE Standard 55 thermal comfort tool and the other is a mean radiant shoebox analysis and visualization model. Both include the recent Addendum G to Standard 55, which added a calculation method accounting for the comfort effects of direct solar on occupants. Topics will include: advanced visualization of the Standard 55 comfort zone, local discomfort determination, clothing ensembles, direct solar, LEED thermal comfort credit documentation, shortwave vs longwave radiation, glazing properties, and others.
