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.
Ens fixàrem en habitacions ventilades de forma natural, a on l'hospital va llevar la ventilació mecànica en una ala de l'edifici i van forçar l'apertura de les finestres que ja no eren operatives, però les va fer operatives per al nostre estudi.
