Author Tatsuya Yoshino,Akihiko Oyakawa,Akira Hoyano
Summary The present paper describes a field measurement of investigate the heat radiation environment and illuminance in summer under a membrane roof of platform canopies at station. The thermal comfort and illuminance was evaluated using the measurement data of air temperature and surface temperature, etc. The result had a greatest impact on the thermal environment and illuminance under the membrane roof. The result under the membrane roof, which compared with the slat roof, was shown as below;
1) The Mean Radiant Temperature (MRT) was 15℃ lower.
2) The Operative Temperature (OT) was 3.5℃ lower.
3) The illuminance was 6 times or more.
