Public Flats With Implementation of Cross Ventilation In West Jakarta

Abstract

Flats are a strategy that can be implemented to address housing needs on limited land, one of which is public flats. There is a problem with the lack of airflow rate which makes occupants use artificial ventilation to increase the airflow rate in flats units. Natural ventilation can solve airflow problems, with minimal energy use. The use of the cross-ventilation method is more effective than the use of one-sided ventilation. This study aims to discuss the size and location of the openings that can affect the airflow rate in flat’s units so that public flats with good airflow can be created using a quantitative simulation method. The simulation was carried out using the Rhinoceros software and the Butterfly plug-in with a model of an apartment unit with a different configuration of the size and location of the openings. The results of the simulation can be used to design residential flats with different heights, such as with an opening configuration ratio of 2:1:2.5 for a height of 9-24m and 2.5:1:2 for a height of 1-16m.
