  author={Jianli Chen and Godfried Augenbroe and Xinyi Song},
Hybrid ventilation, or mixed mode ventilation, is a technique that uses a mixture of natural and mechanical ventilation for maintaining a thermally comfortable indoor environment for building occupants. With its potential for improving both the energy efficiency and occupants comfort at the same time, its real application benefits across different US climate zones are still not clear, especially considering the possible variations of building context and building properties in real scenarios… Expand
