Salatiga is a city in the slope of Mt. Merbabu and has relatively low-average temperature throughout the year. This means that buildings in the city can have a low-energy consumption design by reducing the use of AC. This is good due to the rising of 0,50 C yearly temperature rise in Indonesia (via BMKG). Airflow is when a certain amount of wind speed which went in through an opening and flow past interior or objects inbetween another opening then make it to outside again. It is the premise of airflow in general with the variables being wind velocity, opening, interior, and the room shape itself. Wind velocity and openings both impact directly in how much the wind can cool the room, while interior and room shape impact the effective area coverage of the wind. Research is done by
changing the variation of the variables in digital experimental model, which is made in Grasshoper using Rhino 6. The application simulates the effects of corresponding variables to room temperature from height 1,5 to 2 meter. The
experiment shows how the variables affects each other. This research is useful to
design a low-energy usage building specificly in Salatiga.
