| Abstract Different radiation types are present in everyday environments, and have a major impact on human thermal perception and ultimately on comfort. In a study with participants, we found that humans perceive long-wave radiation (e.g. a warm wall) differently from short-wave radiation (e.g. sunlight). Straightforward comfort models do not directly account for this difference. In more complex thermal simulations, it is possible to consider such different radiation types. To evaluate this modelling approach, the experimental conditions are recreated and assessed in simulations. In analogy to the study with participants, in the simulation a human manikin with a comfort model predicts human thermal perception. Then, participants’ responses are contrasted to the comfort model predictions. Comparison of simulated and participant-reported results allow identification of deviations between the model and the actual perception, and thereby suggestions for further enhancements of simulations are derived. |
