Investigating natural ventilation performance on apartment units in Jakarta based on field test measurements

The COVID-19 pandemic has changed the way of living many people across planet. In beginning pandemic, when strict lockdown was implemented, numbers individual were encouraged to work from home. city living, high rise apparent and became a global phenomenon. This paper evaluates natural ventilation performances existing apartment units in Jakarta, Indonesia by measuring indoor temperature, airflow relative humidity. research studied three different Jakarta form single-sided or cross ventilation. study conducted field test measurement on with various strategy room volume. Statistical analysis carried out investigate relationship influence between results external weather data collected ERA5. suggested that air condition, especially temperature where significant apparent. Furthermore, this contributed validation predicting airflow.
