Outline of Final Research Achievements

In this research, we developed the system that organizes information to encourage indoor environmental adjustment behavior that is expected to improve comfort, energy efficiency, and satisfaction while placing a low burden on building users, and nudges them of appropriate environmental adjustment behavior. The system was constructed based on the results of simulation in an actual office, and its effectiveness in encouraging the operation of window accessories to introduce daylight was verified. The response was generally positive, with office workers reporting that they felt an improvement in indoor brightness, openness, and viewability. In addition, a reduction in lighting power consumption was achieved.

Academic Significance and Societal Importance of the Research Achievements

世界的に脱炭素社会への移行が急務となっている中、建築分野における温室効果ガスの削減目標は特に高いハードルが課せられている。こうした社会的背景により、建築外皮性能の向上や設備システムの高効率化といったハード面からの省エネルギー化は当然として、建物の利用者が建物や設備の特徴を理解して使いこなすことによるソフト面からの省エネルギー化にも取り組む必要がある。本研究成果は建物利用者に対して、外部環境の変化に応じて適切な運用方法をわかりやすく示して、快適性向上や省エネルギー化に寄与する取り組みとして有用な知見が得られたと考えられる。
