First, the location of the house is a very critical choice point. Many floors and living locations in high-rise buildings are now very non-standard, but real estate developers deceive consumers by saying that their houses are in a good location. In fact, what everyone needs to pay attention to is that the orientation of the house is related to the region, topography, wind direction, and the direction of the surrounding roads.
Second, the place where you live must have appropriate sunlight, and at the same time, the sun must not shine all the time, so the two must be suitable. Houses facing south can maintain sufficient sunlight, especially in winter. Sunlight can also reach the same depth, which is beneficial to the health of your family.
Third, another advantage of a south-facing house is that when the sun shines directly in summer, because it is a south-facing house, your house will not be exposed to strong sunlight, so the living environment at home will be Much better, improves the quality of life.
Fourth, the house facing south is the best house, so we should have a general direction when choosing. I personally suggest that you choose a house facing south or a house facing southeast. You can also choose a southwest-facing house, which is very suitable for lighting.
Fifth, when choosing a house, you can also look at the surrounding environment and facilities, because these factors are likely to affect the location of the building. For example, the roads around the building are not going due east or west. Then it may affect the orientation of the building.
Sixth, we also need to pay attention to the fact that the direction of the living room is very important when choosing a house. I personally recommend that the direction of the living room is south, because if our living room faces south, it can be used in winter. There is plenty of sunshine, and it is well ventilated and cooler in summer!
Seventh, when we choose a house, we should pay attention to the main bedroom orientation, or make our choice based on the orientation of most bedrooms. The best bedroom orientation is south, but it needs One thing to note is that it is best not to lean against an exterior wall, so everyone should pay attention to this.
Extended information:
Building orientation mainly refers to the front facade of the building, or the direction the main facade of the building faces. There are two situations here. One is for residential buildings, the main facade refers to the facade where the main rooms are located; the other is for public buildings, the front or main facade may refer to the most prominent image of the building. and the most important facade, or the facade where the main entrances and exits are located.
The so-called house orientation generally refers to the place with the largest lighting surface. In small Chinese rural bungalows, the door usually has the largest lighting surface. In urban houses, the main balcony is generally the largest lighting surface of each unit.
It will have a certain impact on the lighting, ventilation, noise, energy saving and other aspects of the building. A good orientation will keep you warm in winter and cool in summer, but a bad orientation will not only affect the comfort of living, but sometimes even endanger the health of residents due to ventilation and other issues.
The influence of orientation will be affected by indoor natural ventilation and orientation correction rate:
1. Indoor natural ventilation
Natural ventilation is the use of natural resources to change the indoor A purely "natural" means of adjusting the building environment for environmental conditions. Reasonable natural ventilation organization can effectively adjust the air flow effect and temperature distribution in the building, and can have a significant effect on changing the satisfaction of the indoor thermal environment.
However, since the realization of natural ventilation is a passive method that relies on architectural design, its application effect depends largely on the orientation, plane layout and other design effects of the building. Good architectural design helps to enhance the effect of indoor natural ventilation. Similarly, differences in architectural design will also have a greater impact on the building ventilation effect.
The choice of building orientation has a significant impact on the effect of indoor natural ventilation. Choose an appropriate building orientation so that the main openings of the building are located at reasonable positive and negative pressure positions under natural ventilation conditions, forming an organized structure. Effective air inlets and outlets will form a good air flow field inside the building.
Under the same conditions, when comparing the building orientation that is more conducive to natural ventilation and the original building orientation, the maximum airflow generated indoors increased from 0.24 m/s to 0.82 m/s, half Hours later, the indoor temperature is 0.9°C lower than in the original direction, making the indoor PMV value closer to comfort.
2. Orientation correction rate
At noon, the sun’s altitude angle is small, the path of solar rays through the atmosphere is short, and the direct radiation illuminance is large, the orientation correction rate value is large, as shown in the following: In terms of direction, the south direction has a larger correction rate; in the morning and evening, the sun's altitude angle is smaller, the distance is longer, and the direct radiation illumination is smaller, so the east and west direction correction rates are smaller.
The situation in the north direction is special. Generally speaking, the north direction envelope does not receive direct solar radiation. The main factor affecting its orientation correction rate is scattered radiation. From the calculation results, for example, the load in the Lhasa area The orientation correction rate is 5.3%. It can be seen that the scattered radiation of the sun has an important impact on the orientation correction rate of the heating building.
Therefore, in the actual heating design process, the northward orientation correction rate cannot be ignored as zero, otherwise it will affect the initial investment of the system and the thermal comfort of the northward room. And because the horizontal surface receives direct solar radiation during the entire sunny day, the amount of solar radiation obtained is larger. From the calculation results, it can be seen that both the horizontal load orientation correction rate and the energy-saving orientation correction rate are higher than those of the surrounding areas. The orientation correction rate of the protective structure is much larger.
