Abstract

An energy-efficient building ventilation system is presented that integrates semi-transparent organic photovoltaic (OPV) technology and solar chimney technology. It achieved a wind velocity of 0.25 m/s and electric power generation of about 1.03 W at an artificial light intensity of 320 W/m2, which corresponds to cloudy weather. These results support the basic study of systems combining ventilation and power generation. The integration of solar chimney ventilation with OPV power generation could be a promising system for energy savings in the future. The proposed integration could contribute to the generation of sustainable and renewable energy. View Full-Text
