Design and operation of an extended hybrid ventilation system are fully investigated in this study through an example building. Tools of genetic algorithm optimization, computer fluid dynamics and energy simulation are employed to assist the process. The objective is to maximize natural ventilation while maintain good indoor thermal and air quality. The dynamic operation of vents is based on wi...

Natural ventilation of building provides improvement of internal comfort and air quality conditions leading to a significant reduction of cooling energy consumption. Design of natural ventilation systems for many types of building is based on buoyancy forces. However, external wind flow can have significant effects on stackdriven natural ventilation. Investigation of stackdriven airflow through...
