Abstract
In Sapporo, Hokkaido, a snowy cold region that is handicapped by the external environment, we conducted an indoor environment survey and a questionnaire survey of office workers in an office building with ABW aiming to improve the comfort of the indoor environment. This report presents the results of a survey in the start-up phase of the operation. The study results showed that a comfortable indoor environment was realized by the thermal nesting system and hollow PC exteriors. As a result, the satisfaction level of the office workers with the indoor environment was also high. However, since this survey was conducted immediately after the start of the operation, we could not confirm the effects of Wellness office conversion and ABW introduction on intellectual productivity and Work Engagement.
