In view of the current situation of excessively rapid growth of building energy consumption, a control strategy of external shading louvers based on comprehensive energy consumption is proposed to deeply tap the potential of building energy saving. First, the architectural design software Ecotect is used to establish a simulation model of a shading building in Zhengzhou and import it into the lighting analysis software Daysim and the energy consumption simulation software Energyplus to simulate the annual lighting energy consumption and air-conditioning at 11 kinds of blind angles (15∼165°). For heating energy consumption, take the blind angle corresponding to the minimum comprehensive energy consumption as the opening angle of the dynamic blinds and analyze the comprehensive energy consumption for the whole year under dynamic sunshading. The results show that, compared with the conventional control strategy, the optimized control strategy based on comprehensive energy consumption can greatly improve the building's energy-saving rate.
