@sri_srikrishna @joeyfox85 @Sophiepedia I'm not sure what he means but the utility of ACH depends on occupancy. One person on each side of a lecture hall and you can get away with low ACH with relatively little risk. Fill it up with people and it's a different story.
@sri_srikrishna @joeyfox85 @Sophiepedia 我不确定他的意思，但 ACH 的效用取决于入住率。演讲厅的每一侧都有一个人，您可以以相对较小的风险摆脱低 ACH。把它填满人，这是一个不同的故事。
