Courtyard Placement for Maintaining Air Movement of Natural Ventilation inside a Transformed House

A courtyard has effectively induced fresh air into the interior of the house and hence is recommended for inclusion in an additional-room program in a house transformation initiative. However, because of the limited space and the vast choice of room programs that need to be considered in the transformation, it is necessary to formulate the right position of the courtyard. This article sets out the results of research that observed the most effective position of the courtyard. The research was conducted through Ansys 14.5 simulation. The 81 m2 house was simulated as an open lay-out design without any interior partitions. The open layout based simulation is aimed to make the visualization of wind circulation clearly seen. The 9 m2 courtyard is tested in 9 different positions. Based on the simulation, it can be concluded that there are 5 courtyard positions that give positive results for wind velocity, thereby promoting air circulation throughout the entire house area.
