How about the ventilation and lighting of serviced apartments?

Generally, only one side of an apartment project has windows, so single-side lighting and ventilation will also be affected.

The relevant departments have strict requirements on the lighting and ventilation of houses, but there is no requirement for serviced apartments, so there will also be apartments without ventilation and lighting in the north.

In terms of ventilation, air convection can be improved by reforming doors or installing security doors and adding many fences or meshes outside. Lighting can only be compensated by lighting.
