자연적으로 환기를 했던 방들도 보았는데요, 한 병동에선 기계 환기를 끄고 창문을 열어 창문을 열어 더이상 작동할 수 없게 했지만, 저희를 위해 작동을 하도록 해주었습니다.
We looked at rooms that were naturally ventilated, where the hospital let us turn off the mechanical ventilation in a wing of the building and pry open the windows that were no longer operable, but they made them operable for our study.
