| description | A field investigation of the indoor thermal environment and comfort in a typical office building in Qingdao was conducted. During the investigation, the indoor and outdoor environment physical parameters, such as air temperature and relative humidity (RH), were recorded in real-time. The occupants’ thermal responses, basic personal information, and adaptive behaviors were collected. The results showed that the indoor air temperature was from 18.8 °C to 21.6 °C, which was 2–3 °C lower than that during the heating season. Occupants employed heating personal comfort systems (HPCSs), such as electric heaters, air heaters, and leg radiators, to maintain thermal comfort. Based on their requirements for HPCSs, the occupants were divided into three groups-those without HPCS and did not prefer to use (Group A), those with HPCS (Group B), and those without HPCS but preferred to use (Group C). The results showed that the legs and feet thermal sensation of Group B was significantly higher than that of Group C, which made Group B more comfortable. The self-evaluated working efficiency of Group B was slightly higher than that of Group C. Notably, working efficiency was positively related to the overall thermal comfort vote (TCV). |
