Abstract
Architectural lighting is a significant visual stimulus that impacts the occupants' moods and aesthetic experiences within the office environment. Previous literature suggests that the good quality of architectural lighting is considered an important factor that contributes to the visual aesthetic experience of an environment through psychological mechanisms. Lighting uniformity, luminance distribution, and direct/indirect lighting have been discussed in other studies, but lighting spatial patterns are unclear. In particular, assessing the combined effects of lighting parameters on human mood and visual aesthetic experience is challenging. Featured film scenes depicting office environments offer convenient material to study the effects of Lighting on occupants' visual perception and mood.This thesis presents the result of an exploratory mixed-method approach to determine how human-centered lighting design affects occupants' mood, visual aesthetic judgment, and visual preferences in open office spaces. Six spatial lighting patterns of open office workstations were analyzed using image content analysis of selected film scenes. The six rendered images were presented to 60 participants via an online survey to determine their preferences, interests, and aesthetic judgments. This research has revealed that two light spatial patterns were significantly preferred among the six lighting spatial patterns. The first lighting spatial pattern (LS-3) that the overall low average luminance environment, equipped with work view region lighting, which also has a higher luminance ratio (R), is visually preferred. In terms of the higher overall average luminance environment (LS-4), people preferred the overall uniform luminance without desk area lighting with a low luminance value (R). The study also indicated that subjects’ aesthetic judgment (mood repones) and the lighting spatial patterns (LS- 3) within lower overall average illuminance and only equipped with diffused pendant lighting and desk area lighting triggered visually felt more pleasant, relaxed, and satisfied.
