Doors in vain
Problem description: The automatic doors installed at the south and the northeast of the Duderstadt center often open in vain because the sensors detect persons who go to the restroom. These unexpected open may make people who do not get out of the doors bewildered, waste electricity and lead the inefficiency of air conditioning or heating.
The door to outside opens when a person is passing by the door.

When we go through door A, door B opens spontaneously.
Proposed solution:
(Solution 1) Adjust the sensor to make the area small.
(Solution 2) Remove the door A. Two doors are not necessary in this direction.
