A hotel founded in 1880s in a famous hot-spring area underwent a renovation of some guest rooms, corridors, big baths, and exterior after the Great East Japan Earthquake. Our tasks included: to build a comprehensive lighting design that makes the hotel unique and competitive; to design an extraordinary atmosphere in the rooms and stairs; to create gorgeous night view. Our lighting design concept was "The allure of Japan" All interior light sources are high color-rendering LEDs. The hotel's main feature is the beautiful waterfall and the garden stage view from the lobby and guest rooms. We created dramatic scenery throughout the garden. Preset one week lighting control system enabled easy operation and energy saving.

本研究は大きな窓面積を有するホテル客室における、暖房時の温熱環境を改善することを目的としている。暖房時の温熱環境を確保するためには、暖房気流の吹出角度と吹出風速が重要である。このため、上下温度分布予測モデルやCFDによる検証を踏まえ、こられを制御可能な吹出口を開発した。実測の結果、開発吹出口を用いることにより、室温立ち上げ時間を短縮するとともに、上下温度差を低減できることが判った。
