At a school built between 1927 and 1929, all exterior windows are to be renovated in accordance with the requirements of the listed building and selectively renewed.

The renovation and restoration of the construction period is planned. A few windows are replaced by replicas of the box windows from the time of construction. It should be taken into account that the paints of the windows at the time of construction contain a lot of lead and zinc and that the work must be carried out in accordance with the specifications of TRGS 505.

The renovation of the windows will be carried out during ongoing school operations. The measure is divided into construction phases, so that the rooms of the construction phase to be worked on are free of uses.
