Abstract: In order to overcome the energy consumption problem of energy-saving technology in traditional urban power supply system, a new passive energy-saving technology for building planning is proposed. Based on the Ecotect tool, the best orientation is obtained, the digital simulation method is introduced and combined with the characteristics of the building itself to carry out the digital simulation, so as to realise the design of photovoltaic array. The output cables of solar cell module arrays are connected separately, so that each connection has a certain order, thus improving the fault tolerance of the system. The experimental results show that the proposed method has a high photovoltaic power generation capacity of 1726 kW and a low annual energy consumption of about 15 Wh/m². It is proved that passive energy-saving technology has better performance and higher reliability in power supply system.

Keywords: building planning; passive energy-saving; power supply system.
