Post-Occupancy Evaluation of Several U.S. Government Buildings

摘要

A post-occupancy evaluation was performed on five small, low-rise U.S. government buildings at a site south of Washington, D.C. to evaluate environmental conditions including lighting, space, noise, and indoor air quality, and provide recommendations for change. In addition, a comparison was made of environmental conditions before and after renovation of one of the buildings. The study employed a questionnaire about the environmental conditions, physical measures of the space (lighting, space, noise, temperature, etc.) and interviews with personnel at the site. A total of 308 people participated (including measures before and after the renovation) and physical measures were taken at 92 work stations. Analysis of the physical measurement data indicated problems with limited space, lack of adjustable task lighting, and perceptions of poor indoor air quality in two of the buildings. The renovation was perceived to have improved the appearance of one building substantially, however. Suggestions for improvements to the buildings at the site were also made.
