Abstract(in English) It has become a major challenge of the 21st century that productivity improvement of service and knowledge workers. In this study, using big data of 88 people, 552 days and 5 million points from wearable sensor, we discovered that the room temperature is correlated to happiness for the first time. Moreover in individual level, the correlation coefficient, and its signs are found to be different. Based on this result, we propose productivity improvement system by changing the temperature adjustment of each individual.
