Distance between buildings
When buying a house, it is necessary to pay special attention to the distance between surrounding buildings. Priority should be given to apartments that are not blocked by high-rise buildings in front, as this directly affects the ability to receive wind and circulate air. Apartments that are blocked from front to back often find it difficult to create convection, easily falling into a situation where there is draft but not airy.
Building location and wind direction
In some buildings, the pressure difference between the wind-receiving surface and the wind-hidden surface is not large enough, making it difficult for air to circulate naturally. Therefore, apartments with airy spaces both in front and back should be chosen to ensure more effective ventilation.
Building structure
Buildings designed with each elevator serving 1-2 apartments/floor often have better ventilation systems than those serving many apartments per floor. Among large apartment floors, apartments in the middle are often the most airtight. Therefore, it is advisable to prioritize corner apartments or apartments with few neighbors sharing corridors to increase ventilation.
Layer selection
The higher up, the better the ability to receive wind and natural ventilation. However, it is also necessary to avoid some ideal floor spaces: Floors 1-4 are easily shielded by green trees or surrounding structures. Floors 9-12 are often areas where dust accumulates in the air.
Therefore, floors from 5-7 or from floor 12 and above are often considered a more reasonable choice.
House direction
Houses with a North-South ventilation direction are often highly appreciated for taking advantage of natural winds all year round. However, an important condition is to have windows that can be opened on both sides to create cross-wind.
In case you cannot choose a house with this direction, you should prioritize: South direction (more airy and stable). Then Southeast direction (welcoming cool winds but possibly humid in the rainy season).
Conversely, houses without cross-wind directions are often cold and dry in winter (North and Northwest winds), but hot and humid in summer, affecting the quality of life.
