Fountain and Huizenga (1995) conducted a comprehensive literature review of thermal comfort models. Significant advances in thermal comfort modeling have been achieved since that review. The present paper summarizes the advances in thermal comfort modeling for both building and vehicle HVAC applications that have occurred since Fountain and Huizenga’s literature review. This paper is intended to describe the potential use of these models and to demonstrate their suitability for predicting comfort during complex transient and non-uniform environmental conditions. Promising areas for both basic and applied research are also discussed.Units: SI
