There have been lots of studies on the relationship between office room environment and workers’ intellectual productivity such as room ventilation, temperature, humidity and sound noise, however, there are no established method of measuring the intellectual productivity. The authors have been developed CTR (Concentration Time Ratio) which expresses the time ratio of their concentration on the target intellectual work. In this study, a new index CDI (Concentration Depth Index) was developed to realize an analysis from a new viewpoint of concentration depth which is thought to have a relationship with the quality of concentration.
