Abstract
Productivity has become popular in Japan as the new axis for evaluating office environment. In this study, we have applied an original questionnaire based on SAP (Subjective Assessment for workplace Productivity, Version1.2) in existing medium class office building. In this case, the location of the reporter has been collected, and we have examined how to use the information and necessity in the future. In addition to these examinations, we have suggested the effect of energy conservation by improving indoor environment quality.
