Description
Summary:•Automatic airflow intervention was developed by digital twins for facade preservation.•A novel atomizer was developed to disperse the airflow for diluting air pollutant.•Wind direction effect on air pollutant concentration around the facade was quantified.•A novel fresh air curtain wall was developed to preserve facade from air pollutant.•The sulfur dioxide concertation at most effective location reduced by 34 %.
