The performance of ventilation in internal buildings affected by differences of building orientation

Abstract

Natural ventilation is a passive cooling strategy with maximize of airflow into the building. Profil of hills and building orientation are some factor that influences the air quality, and it can control the wind speed. By the author's previous research that building with configured in a grid pattern on the contoured land has enhanced the airflow quality than the grid pattern applied on the flat land. That condition affected building adaptation, such as good position of the opening in the building can optimize the utilization of airflow as the refreshment. This study purposed to evaluates performance of building ventilation of grid patterns on the hillside. This study using Jacky Chan Settlements that was located in Neuhen, Aceh Besar, Aceh Province, Indonesia. Computational Fluids Dynamics (CFD) Fluent used to analyze how far the performance of ventilation in the internal building. This study found that the pattern of airflow and the airflow quality in the room influenced by orientation. All orientation in the settlements created good cross ventilation with differences in wind speed. Contribute of this study is can be a reference for designing better settlements in a contoured land.
