Sidewall radiant heating creates a non-uniform thermal environment. In office buildings, it is important to know how to supply fresh air to reduce radiant asymmetry without causing draft. As a solution, diffuse ceiling ventilation (DCV) is used to supply fresh air into a sidewall radiant heated room. 20 subjects (10 males and 10 females) were recruited and subjective assessments were obtained. The results show that under the influence of sidewall radiant heating, there are differences in the subjects’ requirements for airflow and wall temperature on both body sides. Skin temperature and thermal sensation of the same body parts decrease differently when the subjects move away from the radiant heating panels, especially in forearms, shanks and feet. DCV airflow with low supply momentum interacts with thermal plume formed by radiant heating panels.
