When we buy a new house, the most important thing is to consider the lighting of the house. If the houses with poor lighting will be rejected, what factors will affect the lighting effect of the house? Let's have a look
Indicator 1: floor spacing and floor height
On this issue, a general principle is: the greater the floor spacing, the higher the floor, and the better the daylighting.
The probability of being blocked by other buildings is very low when the building spacing is large or the building is large. The sun can shine into the house without blocking.
As for the building spacing, you just need to pay attention to the time when the sun can shine into the room in the morning and leave in the afternoon.
For projects without occupancy, you can stand outside and observe to see whether the floor spacing between the two floors is reasonable (usually the floor spacing should be more than 1.2 times the building height). If the spacing is too small, the daylighting will be affected.
Loudu is talking about buying a house on several floors. Generally speaking, the tower is good to buy a house with more than 6 floors, while the plank building is no less than 3 floors.
I would also like to remind you that high-rise floors have good daylighting and direct sunlight in summer. In the early morning, the house will be brighter, especially in the east or southeast, which will affect everyone to sleep in;
In the middle floor, the sun will be blocked by the front buildings in the morning, and after a while, that is, in the morning, the sun shines obliquely, which is more convenient for drying clothes and more in line with people's living habits.
Indicator 2: the orientation of the house
South: sunny, transparent from north to south, warm in winter and cool in summer; It seems to be an ideal direction.
Southeast: good daylighting, slightly insufficient ventilation, easy to be wet;
Eastward: there is sunshine only in the morning, the ventilation is poor, and it is not warm enough in winter. Because after all, the sunshine temperature in the morning is still very low.
North: poor daylighting and cold winter. The advantage is that it is cool in summer and saves a lot of air conditioning electricity.
Westward: the daylighting time is short. It is hot in the West in summer, but warm in the West in winter. This mainly means that after a whole afternoon of drying in the house, people come home at night. It's very uncomfortable in summer. It's better in winter. They can feel the residual temperature of the sun.
Southwest: good daylighting and serious problem of western sun exposure.
Indicator 3: house type layout of the whole floor
Try not to choose the house with concave facade on the same floor, and the daylighting will be blocked by adjacent rooms.
Indicator 4: the number and area of daylighting windows of the house type itself
Only through windows and balconies can the sun shine in. Theoretically, houses with three daylighting in the southeast and West have good daylighting effect.
The larger the window, the better the daylighting. For example, French windows not only have good lighting and landscape, but also make the whole room look tall. But we should pay attention to this point: Although large-area daylighting windows are good, we should pay attention to the thermal insulation and sealing performance of daylighting windows. If the thermal insulation and sealing are not good enough, it is easy to make the temperature and humidity in the house unstable, and it is also impossible to obtain a more comfortable living space.
Indicator 5: the space and depth of the house
Traditionally, we call the main lighting surface of the room as the Bay, and the one perpendicular to it as the depth.
For example, for a house with a pure south direction, the south facade is the main lighting surface, and this horizontal wall is the Bay, or face width.
The larger the Bay and the smaller the depth, the better the daylighting of the house; The lighting of houses with small bays and large depth is not ideal. This should also be taken into account when buying a house.
Indicator 6: it is necessary to consider surrounding factors
If the overall buildings of the community are low, the surrounding tall buildings will more or less affect the daylighting.
