自然通风是降低建筑制冷能耗的最基本技术之一。注重能源的设计师利用环境空气的冷却能力来提高室内热舒适性，并最终减少主动空间调节的必要性。混合通风是利用自然力（风和温度）来调节建筑物，在自然力不足时补充使用机械力。自然通风和混合通风的实施意味着通过尽可能利用免费自然冷却，更好地利用暖通空调的能耗。本项目的目标是通过评估当前热通风模型的准确性和可用性，促进自然通风和混合通风概念在建筑设计中的应用。引文:ASHRAE研究

Natural ventilation is one of the most fundamental techniques to reduce cooling energy usage in buildings. Energy-conscious designers harness the cooling capacity of ambient air to increase indoor thermal comfort and ultimately lessen the necessity for active space conditioning. Hybrid ventilation is the use of natural forces (wind and temperature) to condition a building, with the supplemental use of mechanical forces whenever natural forces are inadequate. The implementation of natural and hybrid ventilation represents an opportunity to make better use of energy consumption for HVAC, by utilizing free natural cooling as much as possible. The goal of this project is to advance the use of natural and hybrid ventilation concepts in building design by assessing the accuracy and usability of current thermal-ventilation models.
