Three installation shafts and three technical rooms are planned in the building.
Shaft No. 1
Shaft No. 1 is located in the stairwell area near the sanitary rooms and is intended for the sewer system, connections to solar panels, heating pipes, electrical cables and network cabling.
This shaft has fire-resistant doors on every floor of the stairwell and is designed to remain accessible.
Shaft No. 2
Shaft No. 2 is located next to the chimneys. Risers for drinking water and hot water are to be installed here.
Shaft No. 3
Shaft No. 3 is located behind the wall hydrant and is intended for an empty fire-fighting riser as well as a rainwater downpipe.
Также концепцией предусмотрено три технических помещения:
• Central technical room on the lower basement level (TRzentral)
• Room in place of the former cesspit (TRgrube)
• Room in place of the former toilet directly above the former cesspit (TRprivet)
Central Technical Room
The central technical room on the lower basement level is connected to installation shaft 1. An electrical cabinet with space for ten meters is to be mounted on the wall adjoining the former pit. The connection to the distribution boards in the apartments runs directly from shaft 1. The remaining electrical installations of the building should be placed in a floor-standing cabinet directly next to shaft 1. An additional floor cabinet or wall niche is planned as a reserve.
Room in Place of the Former Cesspit (TRgrube)
In the area of the former cesspit a room is designed for installing up to six IBC tanks. The design is based on the standard dimensions of IBC containers. Two IBC tanks are located in a wall niche. Additional containers can be installed in the room. They are intended for collecting rainwater.
Room Above the Former Cesspit (TRprivet)
After the reconstruction of the staircase, the height of this future room will be about 1.8 m, so it should be regarded as a utility or storage room.
Protection Class of Cabinets
All wall-mounted and floor cabinets should have a protection rating of at least IP54. Cabinets of this protection class, for example from the manufacturer Striebel & John, are made entirely of powder-coated sheet steel with a thickness of 1.6 mm. The cabinet doors are equipped with rubber seals. This should improve fire protection.
Pipe Insulation
It must be possible to insulate the sewage and rainwater pipes. For this reason, the installation pipes have appropriate dimensions. Pipes for hot water, solar heat and heating must be insulated in accordance with DIN standards.
Heat Exchanger
Ventilation of the kitchen and bathroom should be controlled and equipped with heat recovery. Next to the chimney there is space for the supply duct (above the roof) for fresh and exhaust air. A heat exchanger is planned to be installed in the area of the upper basement level.
