The basement of high-rise residential buildings is public electricity. High-rise houses and basements are generally two meters. Residential electricity consumption is large, generally need to do storage in the basement, electricity consumption will not be very high. Generally, several households use a meter box, and almost all of them use a large meter box in the basement for collective use among storage rooms. Electronic meters are regularly displayed in many places. An electric meter controls all basements and shows the electricity consumption of a basement for several seconds. However, villas and single-family basements generally share electricity with the owners' homes.

Basement means that the floor height of the room below the outdoor floor exceeds half of the clear height of the room. Multi-storey and high-rise buildings need a deep foundation. In order to make use of this height, building a basement under the ground floor of the building can not only increase the usable area, but also save the backfill soil in the building center, which is relatively economical. Building a basement below the ground floor of a house can improve the efficiency of building land. Some high-rise buildings have deep foundations. Making full use of this depth to build a basement has good economic and practical effects. Basement is divided into ordinary basement and air defense basement according to function. According to structural materials, there are brick walls and concrete basements, and according to structural forms, there are full basements and semi-basements.
