Very similar questions supported by pictures ended up questioned of window openings and doorway openings to determine the behaviours with regard to these ventilation things, the window and door opening extent was also assessed. Conduct concerning the utilization of window coverings including curtains and blinds lift shaft ventilation was gathered.
