1. Daylighting: If the windows in the basement are small, you can make sinking space outside by yourself to increase daylighting, but the cost is high.

The quality of the windows in the basement is very high, because the underground space is most afraid of water. The sealing and waterproofing of the windows are very important. The windows with low quality will be harmful to the living space after being eroded by sunlight and rain.

2. ventilation: in the semi-basement, if windows are opened, it is easy to get dust in the room because it is close to the ground, so most of the time the windows are not opened in the basement. In this case, the indoor air and the outside air can be exchanged by installing ventilation fans, and more fresh air can be introduced into the room.

You should use a high-powered range hood and a ventilator in the kitchen. Actually, the fume problem can't be solved much with a ventilator, so it's best not to cook food with large fume often in the kitchen.

3. Moisture-proof: To be on the safe side, you'd better waterproof the ground and walls before you move in.

it is best to use bricks instead of wooden floors.

4. heating and air conditioning: the basement is grounded in summer, which is very cool.

But it's very cold in winter. When heating, the amount of radiators must be more than the above-ground space, and heating should be stronger than the above-ground space.

if air conditioning is used, the power should be higher than that in the same space on the ground.
