ScholarBank@NUS Repository.||Abstract:||In 1972, the late Asian architect Geoffrey Bawa designed a naturally ventilated 12-storey office building in Colombo, Sri Lanka, The building incorporated many environmentally responsive design principles long before the buzzwords of bioclimatic and sustainable architecture became commonplace. Bawa designed a monsoon window façade that would allow airflow into the building even when the windows are closed during rain. The building construction completed in 1978 but unfortunately, it was not used as originally intended. Shortly after the expatriate occupants moved in, air-conditioning units were installed. The office interior was partitioned up into many sub units instead of an open plan layout, thus impeding airflow. The paper investigates the effectiveness of the façade profile for natural ventilation as originally designed and lessons we can learn from it. It examines the performance of each element of the façade. Measurements are done using a physical model in wind tunnel tests. The project details of this building is obtained from archival research, visit to the building and interview with the original design team.||Source Title:||Sun, Wind and Architecture - The Proceedings of the 24th International Conference on Passive and Low Energy Architecture, PLEA 2007||URI:||http://scholarbank.nus.edu.sg/handle/10635/45490||ISBN:||9810594003|
