The choice of building orientation should meet the requirements of more sunshine in winter and avoiding too much radiation in summer. According to the geographical location of our country, buildings facing south and its adjacent direction can meet this condition. However, due to the limitation of terrain, some rooms will be exposed to the west.
The solution to the problem of sun exposure is to use curtains with shading screens. This method can prevent the entry of sunlight heat to a considerable extent, but the disadvantage is that there is no natural light indoors at all.

The harm of western photos:
1. The intense west facing in summer will make the temperature of the west facing room rise a lot. The huge heat released by sunlight through the glass exposed to the room will lead to huge energy consumption of air conditioning operation and increase the electricity bill.
2. Every house facing the sun in the west is not ventilated and the wind does not enter the house in summer. In winter, the northwest wind blows, and even if the windows are closed, the wind will get into the house.
3. The indoor temperature of Xiyang Light Room is 2-3℃ higher than other rooms in summer.
