Research on the Light Environment of Chochikukyo (Part 1)：physical Environment Measurement

Chochikukyo is a residence built by architect Koji Fujii utilizing environmental engineering expertise, emphasizing harmony with nature. It was designated an Important Cultural Property in 2017. One key element is its light environment. The residence is positioned to maximize the surrounding natural environment, designed with careful consideration for natural light intake and airflow. While thermal environment measurements have been conducted, light environment measurements have not yet been performed. This study aims to clarify Chochikukyo’s light environment characteristics by measuring its physical environment during summer and autumn.
