4. Closed doorway

This door opens when an employee wearing
an ID badge approaches. A computer system maps where people/ID badges are in a building and opens or closes doors automatically to allow or limit air flow.

In winter the doors are likely to stay shut to prevent draughts, convection and heat loss. In summer the doors may be open to maximise airflow (unless they are fire doors that need to stay shut).
