The importance of the office well-being has been widely discussed. There are many factors that affect the productivity of office workers, and the well-being of their working space is a significant factor. The indoor environmental comfort is also evaluated in several certification systems. On the other hand, these environmental factors are generally evaluated for the entire space and are not evaluated according to the location and intentions of individual person.
To achieve sustainable office management, it was deemed necessary to consider both the working environment and energy efficiency. We assumed that a new office well-being index by seat-specific task would contribute to enhance workers’ satisfaction, and less energy consumption could be evaluated by considering those satisfaction together. Task are classified into three forms based on work content: F (focus), N (normal work), and R (relaxation). The index is scored based on six office environmental elements (temperature, humidity, illumination, noise, equipment, and privacy) selected from preliminary studies, and the significance of the difference in rankings is confirmed through a ranking survey. We used
directly evaluative methods to determine the usage-specific weighting coefficients of each element. From January to August 2022, we conducted surveys in the model office located in Tokyo and determined the model equation based on the usage-specific weighting coefficients. Secondly, based on the indicators for improving well-being by seat/task and with the aim of achieving energy efficiency while maintaining satisfaction, we conducted a field experiment in the model office. Illumination and temperature were set in certain degrees, followed by verifications of a significant change in the index evaluation results due to changes in the office environment, and a reduction in power consumption of PAC indoor units and illumination.
