Project

Renovation and expansion of the Schiller School Mannheim into an all-day school, 3rd construction phase of the gymnasium

Location: corner of Germaniastraße and Luisenstraße

specifications

The free-standing "gymnasium" structure consists of two single-field gymnasiums arranged one above the other and four floors with serving rooms (changing rooms, sanitary, equipment and technical rooms, etc.), with two floors each assigned to a gymnasium.

On the south side is the staircase in front, on the intermediate landings there are further sanitary rooms. On the north side, there is an external steel staircase as the second structural escape route from the upper gymnasium.

The free-standing gymnasium is located in Mannheim-Neckarau and was built as a reinforced concrete skeleton structure in 1962.

The school building itself has already been renovated, the heat supply of the gymnasium, as well as drinking water supply, is provided by the newly set up technical centers there.

Heating system

On the 3rd floor of the gymnasium, a control center for a new HVAC unit or a sub-center for the heating installations will be built. On the 1st floor, the central water heating system for the washing and shower areas will be set up.

During the planning of the heating trade, care was taken to ensure that various fire compartments were only driven through with pipes made of non-combustible materials. As a bulkhead for these wall and ceiling passages, resin-bonded pressure-resistant rock wool shells are used to comply with fire protection.

The distribution lines for the connection of the radiators are laid on the same floor, within the suspended ceiling. Tubular radiators of the appropriate height are provided for room heating of the gymnasium adjoining rooms. The two single-span gyms are heated by radiant ceiling panels.

The planning envisages that all radiators necessary in a room will be supplied via a common connection to the ceiling distribution. This means that the individual room control required by the client can be implemented via a control valve with an upstream strainer and corresponding shut-off and regulating valves. For access to these fittings, inspection openings of the appropriate size are provided in the suspended ceiling on site.

For mechanical ventilation of the gym adjoining rooms, an HVAC unit with a therm. Air treatment planned.

The device design complies with the applicable ErP guidelines. Ancillary rooms are approached via a centrally located shaft.

As is already the case, the heat supply for the gymnasium will continue to be from the central heating system in the school building. Between the school and the gymnasium, new heating connection lines will be laid in the ground at a frost-free depth.

The existing heating system in the basement of school building 3 will be dismantled and rebuilt according to future requirements.

The existing heating system is designed in such a way that both the two already completed construction phases and the gymnasium that is now to be renovated can be supplied with heat.

All existing heating pipes, radiators, etc. are dismantled and disposed of on site.

Important NOTE:

The connecting line between the school building and the gymnasium will be carried out as an early measure.
