The commissioning meant a process in which, after detailed study and analysis of the operational performance of the existing building, the client’s conditions were written down in such a manner that the document would provide the basis for renovation design and construction as well as for ongoing operation and management. By these means, the highest-standard equipment available at the time could be installed, and the building ceased to be an “energy intensive” building once and for all. 345Photography｜1: 提供 京都駅ビル開発 株式会社／Courtesy Kyoto Station Building Development Co., Ltd. ｜2–5: エスエス／SS　1 : 建物外観（北面）。｜2：再生可能エネルギーの活用を図るため設置した太陽熱集熱パネル。集熱したエネルギーは、給湯設備へ供給する水の予熱に利用している。｜3–5：今回採用した空冷ヒートポンプチラー、高効率ターボ冷凍機、ボイラー。既存システムの綿密な調査・分析をもとに、最適な熱源システムと熱源容量へ切り替え、低カーボンエネルギーへの転換を測った。1 : Exterior view of the building (north elevation).｜2: Solar thermal collectors installed to utilize reusable energy. e energy collected is used to preheat the water supplied to the hot water supply system.｜3–5: Air-cooled heat pump chiller, high eciency turbo refrigerator, and boiler selected for the project. Based on thorough study and analysis of the existing system, an optimum heat-source system and heat-source capacity were introduced, and the system was converted to a low-carbon energy system. 132019 AUTUMN40Feature | WORKS
