3.4. General Results
- The lot perimeter wall affects the wind field surrounding the house. The lot perimeter wall results in a decrease of fresh air coming inside the house and its surroundings. This will result in a reduction of natural ventilation and fresh air, and will increase discomfort and lower indoor air quality. Hence, this also results in the application of mechanical means such as air fans and air-conditioning systems that result in the increase of energy consumption of the house.
- Opening the doors and windows is significant in the cross flow ventilation in the house, as shown in the different cases. As presented, it is very important to open the bedroom doors to increase the wind passing through the room for natural ventilation, particularly in the case of the rooms with windows on one side only.
- To avoid air recirculation and stagnation, particularly in the detached house with a very high lot perimeter wall, it is important to consider opening some portion of the wall to increase the wind passing through the house to minimize air stagnation and recirculation that might result in poor ventilation and air quality. The opening at the left of the lot perimeter wall, as presented in the study, shows the increase in wind passing through the house.
