Occupant evaluation of commercial office lighting: Volume 2, Preliminary data analysis
- ed.
This report presents the preliminary results of a post-occupancy evaluation of office lighting environments. It explores the relationship between quantitative measures of lighting in occupied environments and qualitative measures related to occupant satisfaction. The report analyzes several types of data from more than 1000 occupied work stations: subjective data on attitudes and ratings of selected lighting and other characteristics, photometric and other direct environmental data, including illuminances, luminances, and contrast conditions, indirect environmental measures obtained from the architectural drawings and the work station photographs, and descriptive characteristics of the occupants. The work stations were sampled from thirteen office buildings located in various cities in the United States. Many tentative findings emerged from the analysis, including the following: (1) within the range of values examined here, there is a tendency for lighting satisfaction to decrease as lighting power density increases; (2) occupants who described their work station spaces as bright also tended to be satisfied with their work station lighting; (3) occupants who were most bothered by bright lights and glare were most likely to express dissatisfaction with the lighting at their work stations; (4) there is no relationship between work-related activities of employees and indicators of lighting quality. More research is needed before firm conclusions can be drawn and before guidance regarding lighting standards and other policy issues can be derived. 3 refs., 9 figs.
