Surveying impacts of adaptive facades on acoustical quality of classrooms

Acoustical quality greatly affects the performance of classrooms. Classrooms with decent acoustics will provide good communication between students and teachers as well as between attendants themselves. In order to meet the requirements of user-amenity acoustical quality assessment standards such as United Kingdom Building Bulletin 93 or ANSI Standard S12.60-2010 was introduced. The usage of adaptive façades for buildings is a passive design solution for improving natural daylight, energy intensity and also partially impacts speech intelligibility inside classrooms. In this study, a typical classroom model was placed in Ho Chi Minh City to survey the Reverberation Time (RT) and Sound Pressure Level (SPL) through the effects of adaptive facades, particularly in the form of Kinetic Adaptive Facades. The façade phenotypes showed better improvement in SPL and RT than the case without Kinetic Adaptive Facades, and at each phase change of façades also showed a decrease in RT and SPL
