Abstract

Abstract Nearly Zero-energy residential buildings have attracted widespread attention due to their superior energy-saving performance. In order to achieve a balance between energy production and demand in residential buildings, the application of renewable energy is essential. This paper optimizes typical zero-energy public buildings in hot summer and cold winter locales using the concepts of passive priority, active optimization, and 100% renewable energy supply guarantee. The importance of passive energy-saving techniques like heating, shading, and heat recovery; in accordance with local resource conditions; analysis of building renewable energy utilization systems like solar energy and air energy; and recommendation of the most technologically efficient building energy system. According to the simulation results, if the criteria for zero-energy buildings are met, the annual energy consumption index per unit area is 37.6 kWh/m2, and the 8.9 kW building photovoltaic system can generate 36.4 kWh/m2 of power annually.
