The unit electricity consumption index of office buildings is 30~70W/m (du50~100VA/m). This index can be used to calculate the electricity consumption of office buildings.
The electricity consumption of an office building is: area × electricity consumption index.
Assume a 3000m2 office building
Then the electrical load is: 3000m2 × 60W/m2=180kW (3000m2 × 80VA/m2=240kVA) (inclusive Electricity for lighting, sockets, air conditioning and other equipment).
For details, please refer to the National Civil Construction Engineering Design Technical Measures "Electricity" 2009, Table 2.7.6 Electricity consumption indicators per unit building area of ??various types of buildings. Office building: The power consumption index is 30~70W per square meter, and the transformer capacity index is 50~100VA per square meter.
Extended information:
The electric charge of an electron is e=1.60*10-19. Experiments have pointed out that the charge of any charged particle is either equal to the charge of an electron or a proton, or an integer multiple of their charge, so the 1.60*10-19 library is called the elementary charge.
Electricity can also refer to the amount of electrical energy required by electrical equipment, which is also called electrical energy or electrical power. The unit of electrical energy is kilowatt·hour (kW·h). W=P*t (W represents electric energy; P represents active power, the unit is kW; t represents time, the unit is hours h). The electricity here is also divided into active electricity and reactive electricity. The unit of reactive power is kVar·h.
