The first purpose of this paper is to verify a new method of the post-occupancy evaluation in an office by field survey. The second purpose is to find the effects of building moving and a time lapsed on occupants' evaluation of their working environment. The environmental variables(thermal, sound, light, air quality, color and space conditions) were measured and the questionnaire with 39 questions was conducted on the occupants at the same time. The office occupants' evaluated that the new office environment was better than the previous one at building moving, but there wasn't a significant difference between the previous and new buildings in the factory occupants evaluation. The effect of the time lapsed was found in the evaluation of spaciousness, color coordination, neatness etc.. These occupants' evaluations fairly coincided with physical environmental conditions. Consequently, the effect of working environment on the occupants evaluation can be found by this study's method.
