Is it better to sun the house facing east or west

Houses facing the sun in the east can be exposed when the sun rises in the morning. Generally, it is warm in winter and cool in summer, which is very popular with everyone. The sun in the west is not good, it can only be sunny in the afternoon, and it is better in winter, but it will be as uncomfortable as a steamer in summer.

When the sun just rises, the temperature in the east sun room is usually low in the morning, and there is less heat transferred from the outside to the inside. Although the sun shines directly on the east wall (above 60-90 degrees) at this time, the radiation intensity is also very high, but it belongs to the stage of boiling frogs in warm water, and people will not be too uncomfortable. The impact on the room is not too great.

Nanwu was radiated when it was very hot at noon, and the temperature rose a lot accordingly, which increased the heat conduction. However, the intensity of oblique radiation is much less than that of direct radiation because the sun's irradiation on buildings becomes oblique (about 30 degrees included angle). Relatively tolerable.

The laundry room in the west receives sunshine in the afternoon. After heating in the morning and at noon, the indoor and outdoor temperatures have risen to a certain extent, reaching a fairly high temperature of 30-40 degrees. Such a high outdoor temperature is transmitted to the room through the wall, and its strength reaches the maximum. At this time, as the sun moves westward, the sunlight becomes direct again, and the radiation intensity is greatly increased. In this case, the western wall is very hot, and the temperature of the house in the west is several degrees higher than that in the east. This is the root of the problem of sunbathing in the west.

Finally, I want to give you a suggestion. It is best to stick a glass insulation film on a particularly hot house. This is an excellent way to solve the problem of sun exposure, and it will not affect your lighting, saving trouble and money.
