Passive ventilation cooling strategies on modern architecture

With the increasing number of compound or deep-plan buildings, application and research on passive ventilation cooling system in construction is developing from single and directed way to multiple and indirect ways,from not easy to control to easy to control, from simplicity to systematization. This paper summarizes four kinds of passive ventilation cooling types. Their techniques and adaptability are discussed .The disadvantage of natural ventilation cooling is pointed out. It proposed that indirect controllable ventilation cooling may be used in large depth, enclosed public buildings.
