Lighting and ventilation of north-facing rooms
The angle of sunlight is sunny in the south and relatively dark in the north. Therefore, the lighting facing south must be ideal, not sunny in the east and sunny in the west. The ventilation in the north and south is also good, and it is of course comfortable to live in. Most of our country is in the north of the Tropic of Cancer, and the sun shines from south to north all the year round. There is basically no direct sunlight in the windows facing north, and the light is not enough. Especially in winter, under the influence of the northwest monsoon, the room facing north will be colder.
