How to determine the best floor based on the sun altitude angle? How much does the sun altitude angle affect the price difference between floors?
When buying a house, you must fully consider lighting and ventilation issues. Living on floors with good lighting will be more comfortable. If you want to have longer sunshine hours, you still have to learn to judge which floor is best based on the sun’s altitude angle. It is the best floor, so how do you determine the best floor based on the sun’s altitude angle? How much does the sun’s altitude affect the price difference between floors? Follow us to find out!

In order to obtain sufficient sunlight on the bottom floor of the building, generally speaking, the distance between buildings is smaller in areas with lower latitudes, and larger in areas with higher latitudes. Mainly because the higher the latitude, the smaller the sun's altitude angle, and the longer the shadow. In order not to affect the shadows between buildings, it is necessary to choose an appropriate distance between buildings. For example, in my country, when building a house in the area north of the Tropic of Cancer, in order to ensure that all rooms on one floor have sunlight all year round, the shortest distance between the two floors is related to the height of the building. It should be as shown in the picture on the right (α is the local noon sun height on the winter solstice), and L should be greater than or equal to h·cotα. Why should we choose the solar altitude angle on the winter solstice? Because in most areas of our country, the solar altitude angle on the winter solstice is the smallest and the shadow is the longest. If the shadow of the winter solstice does not cover the building, then the building will have sunlight all year round.
So, when choosing floors, try not to choose the bottom floor, because sometimes the floor spacing is not considered during real estate development, which will result in the rooms on the bottom floor not getting sunlight all year round. This also makes the price of low-rise houses in the same building generally cheaper. Finally, when choosing a house, you should also consider the direction of sunrise and sunset. For example, in the summer half of the year in my country, the sun rises in the northeast and sets in the northwest; in the winter half of the year, the sun rises in the southeast and sets in the southwest. Therefore, west-facing houses have the possibility of receiving western exposure, which will also lead to a lower price for west-facing houses. Of course, many times we cannot see the existing house, so if you buy a second-hand house, you must consider it carefully.

In order to obtain more sufficient sunlight, determine the orientation of the house relative to the position of the sun at noon. In areas north of the Tropic of Cancer, the noon sun is in the south and houses face south; in areas south of the Tropic of Cancer, the noon sun is in the north and houses face north. Therefore, most of the houses in our country face south, which is conducive to obtaining sufficient sunlight. Especially in the northern areas, it is recommended to buy a house facing south as much as possible. It won't be too cold in winter. In addition, our country blows cold and dry northwest winds (northeast winds) in winter, so it is best not to buy a house facing north. Therefore, in the same building, the price difference between the north and south directions will be 1000-2000 per square meter.
There are many factors that influence the price difference between floors. It is not decided by the developer’s mood, and of course it is not just due to the influence of the feng shui of the floor. A very important factor is the influence of the sun's altitude angle. If you want to have longer sunshine hours, you still have to learn to judge which floor is the best floor based on the sun's altitude angle.
How to judge the best floor based on the sun’s altitude angle? How much does the sun’s altitude affect the price difference between floors? The above is the relevant content we introduced. There are many factors that affect the price difference between floors. Generally, good lighting The floors are relatively expensive, so it is better to choose floors above the middle floor.
