To understand how transition across different thermal zones in a building impacts the thermal perception of occupants, the current work examines occupant feedback in two work environments — nursing staff in hospital wards and the workers in an office. Both studies used a mix of subjective surveys and objective measurements. A total of 96 responses were collected from the hospital wards while 142 were collected from the office. The thermal environment in the hospital wards was perceived as slightly warm on the ASHRAE thermal sensation scale (mean TSV = 1.2), while the office workers rated their environment on the cool side (mean TSV = 0.15). The results also show that when the transitions were across temperature differences within 2 °C, the thermal perception was not impacted by the magnitude of the temperature difference — as reflected in occupant thermal sensation and thermal comfort/thermal acceptability vote. This would imply that the effect of temperature steps on thermal perception, if any, within these boundaries, was extremely short lived. These findings go towards establishing the feasibility of heterogeneous indoor thermal environments and thermal zoning of workspaces for human comfort.

Activity-based work environments are widely adopted; however, research shows mixed findings regarding privacy issues, satisfaction with the work environment, and task performance. To further our understanding, two complementary studies drawing on Person-Environment fit theory were conducted: (1) A field study using experience sampling, and (2) A lab study in a virtual reality studio. The results from both studies confirm that perceived fit is a function of activity, work setting, and personal need for privacy, with indirect effects on satisfaction with the work environment (Studies 1 and 2) and task performance (Study 2). Across both studies, a misfit was perceived particularly among workers high in personal need for privacy when performing high-complexity tasks in an open office work setting. Hence, we recommend that organizations facilitate and stimulate their workers to create better fits between activities, work settings, and personal characteristics.

This research paper looks at a selection of science-fiction films and its connection with the progression of the use of television, telephone and print media. It also analyzes statistical data obtained from a questionnaire conducted by the research group regarding the use of communication media.
