Lot 10 Heating, ventilation and sanitation
Building Description / Heating-Ventilation-Sanitary
Sewage systems
Building drainage includes the discharge of domestic wastewater from the furnishings to approx. 1m in front of the outer edge of the building.
The drainage of the roof surfaces is carried out via internal or concealed gutters, partly into downpipes in front of the façade, partly into drainage pipes laid inside the building.
The services for the drainage of rainwater begin at the roof drains below the roof ceiling provided by the customer. Wastewater and rainwater pipes are installed up to 1m in front of the
Outer edge of the building. Emergency overflows are recorded on site and shown in the architect's plans.
Water systems
All sanitary facilities in the building are supplied with drinking water. Starting from the
drinking water house connection in the building, with arrangement of the main shut-off device, the
backflow preventer, a water meter and a manually backflushable filter in the
house connection room, a distribution on the ceiling is planned.
Domestic hot water is produced locally via electrically operated instantaneous water heaters.
There are a total of five outdoor taps with frost-proof external fittings, lockable and equipped with
Water meter, provided.
Heat generation systems
The building is supplied with heating medium via an indirect district heating station. The connection is made to the district heating network of SEV Sömmerda. On the secondary side, the district heating station has
Space heating circuits for underfloor heating, depending on the outside temperature.
Heat distribution network
The distribution in the building takes place from the district heating station with stainless steel pipe in the pressfitting system in the floor structure. The cables are provided with mineral wool insulation in accordance with the EnEV. The passage through walls with fire protection requirements is carried out in compliance with the MLAR using rock wool insulation shells.
Space heating surfaces
An underfloor heating system is used to heat the rooms. The plastic piping required for this branches off from a central distribution cabinet. Each room is equipped with a thermostatic room sensor (scope of services HLS). In addition to underfloor heating, the sanitary rooms in the group areas will be equipped with towel radiators with electric cartridge heaters, so that they can also be used outside the operating hours of the underfloor heating.
Ventilation systems, ventilation concept
The kitchen and serving area is ventilated via a central ventilation unit with heat recovery.
The ventilation of the "marketplace" is controlled by exhaust air systems with CO2 control, the inflow takes place via outside air elements.
The ventilation of the interior rooms and sanitary rooms is provided by exhaust air systems or exhaust fans.
The inflow takes place via external air elements in the windows and in the façade. Their control system is designed for basic and on-demand ventilation as well as night cooling.
