How to determine the orientation of the house?
Secondly, the place where you live must have suitable sunshine, and at the same time you can't keep sunshine all the time, so the two should be suitable, while the house facing south can keep enough sunshine, especially in winter, which is beneficial to the health of your family.
Third, the house facing south has another advantage. In summer, the sun shines directly. Because it is a house in the south, you can't get strong sunshine at home, so the living environment at home will be much better and the quality of life will be improved.
Fourth, the house facing south is the best house, and you should have a general direction when choosing it. Personally, I suggest you choose a house facing south, a house facing southeast, or a house facing southwest. The lighting is very suitable.
Fifth, when you choose 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, if the roads around the building are not due east and west, it may affect the orientation of the building.
Sixth, we also need to pay attention to the fact that the orientation of the living room is very important when choosing a house. Personally, I suggest that the living room faces south, because if our living room faces south, we can get enough sunshine in winter, but it is well ventilated and cool in summer!
Seventh, when choosing a house, we should pay attention to the orientation of the master bedroom, or use most bedrooms to choose for ourselves. The best bedroom is facing south, but it should be noted that it is best not to rely on the external wall of the house, which everyone should pay attention to.
Extended data:
Architectural orientation mainly refers to the facade of the building, or the direction of the main facade of the building. There are two situations here. First, for residential buildings, the main facade refers to the facade where the main room is located; Second, public buildings, the facade or main facade may refer to the most prominent and important facade in the image of the building, 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. Small houses in rural areas of China generally have the largest lighting area at the gate. In urban housing, the main balcony is generally the largest lighting surface of each unit.
It will have a certain impact on the lighting, ventilation, noise and energy saving of buildings. A good orientation will make you warm in winter and cool in summer, while a bad orientation will not only affect the comfort of living, but sometimes even endanger the health of residents because of ventilation and other problems.
Orientation will be affected by indoor natural ventilation and orientation correction rate:
1, indoor natural ventilation
Natural ventilation is a pure "natural" means to adjust the indoor environment by using natural resources. Reasonable natural ventilation organization can effectively adjust the airflow effect and temperature distribution in the building, and can obviously improve the satisfaction of changing the indoor thermal environment.
However, because the realization of natural ventilation is a passive method that depends on architectural design, its application effect depends largely on the design effect of architectural orientation and plane layout. Good architectural design helps to enhance the effect of indoor natural ventilation. Similarly, the difference of architectural design will also have a greater impact on the ventilation effect of buildings.
The choice of architectural orientation has an important influence on the effect of indoor natural ventilation. Choosing the right building orientation will make the main opening of the building in a reasonable positive and negative pressure position under the condition of natural ventilation, and form an organized and effective air inlet and outlet, thus forming a good air flow field in the building.
Under the same conditions, compared with the original building orientation which is more conducive to natural ventilation, the maximum airflow generated indoors is increased from 0.24 m/s to 0.82 m/s, and the indoor temperature is 0.9℃ lower than the original orientation after half an hour, which makes the indoor PMV value closer to comfort.
2. Direction correction rate
At noon, the sun's altitude angle is small, the distance of solar rays passing through the atmosphere is short, and the direct radiation illumination is large, so the correction rate of the direction is large, that is to say, the correction rate of the south direction is large; In the morning and evening, the sun's altitude angle is small, the distance is long, the direct radiation illumination is small, and the correction rate in the east-west direction is small.
The northbound situation is quite special. Generally speaking, the northbound envelope can't receive direct solar radiation, and the main factor affecting its orientation correction rate is scattered radiation. From the calculation results, for example, the load orientation correction rate in Lhasa is 5.3%, which shows that the scattered solar radiation has an important influence on the orientation correction rate of heating buildings.
Therefore, in the actual heating design process, the north orientation correction rate can not be ignored to zero, otherwise it will affect the initial investment of the system and the thermal comfort of the north room. Because the horizontal plane receives direct solar radiation throughout the sunny day, the amount of solar radiation obtained is large. It can be seen from the calculation results that both the horizontal load directional correction rate and the energy-saving directional correction rate are much greater than the directional correction rate of the surrounding envelope.
