Optimization Of Natural Ventilation In Building As Passive Design Strategy For Health Security

Abstract

The use of natural ventilation strategy in a building is currently encouraged by the emergence of a pandemic Covid-19. In addition to its advantages in minimizing the use of electrical energy, the natural ventilation system is believed could reduce the possibility of spreading the virus. One design approach to this system is by using the window's design properly. Air movement inside a building should be utilized well to allow the movement from inlet to outlet. The position of the window was one of the variables examined in this study besides the types of the window. This study found that the use of a combination of 300 awnings produced the highest airspeed in the living room (R1), while a combination of horizontal sliding windows resulted in the highest air velocity in the bedroom (R2). Still, the airspeed generated from the two combinations less than the minimum level of it is generally required, 0.75 – 0.9 m/s.
