Moker Area New Mixed-Use Building, Rottweil, Germany

A four-story commercial building is designed with underground parking, retail and office space, and apartments in the attic. In addition to parking spaces, the basement will also house areas for building services.

The two upper floors allow for different types of office use, such as individual, combination, or open-plan offices. Each floor can be divided into several independent rental units. Each rental unit has access to the stairwell and elevator system and can be equipped with its own toilet facilities, kitchenettes, and IT distribution rooms if required.

The street facades are designed as parapet facades with continuous triple glazing. Natural ventilation is provided by openable skylights. An approx. 1.75 m high wooden parapet cladding with a curved lower edge forms the striking facade surface facing the street.

The courtyard facade is constructed as a perforated facade with triple glazing and a reinforced concrete exterior wall. Rear-ventilated brickwork forms the facade cladding. Perforated windows in the masonry facade form the transition to the historic existing buildings.

The roof will be designed as a green roof throughout. The apartment facade on the top floor consists of floor-to-ceiling elements made of aluminum profiles and triple glazing. Doors and windows that can be opened have a tilt and turn function. Like the apartment facade on the top floor, the ground floor facade will be constructed from floor-to-ceiling elements made of aluminum profiles and triple glazing. The facade has openings for fan coil units and window sashes to allow fresh air to flow into the individual rooms. In the event of a fire, the exhaust air fans and, if necessary, the supply air fans are switched off. The fan coil units are equipped with heat recovery for the supply and exhaust air, which makes it possible to condition the fresh air (heating or cooling). The building will be connected to the ENRW district heating network.

The building has external shading and requires very little cooling during normal operation. A cold water system for cooling the building will be installed as a tenant option. A chiller on the roof generates the cold air for this. If necessary, cooling beams, cooling ceilings, or recirculating air cooling units can be connected to the vertical risers of the system.

Digital ballasts are provided for lighting in the rental areas. The bus system for lighting and sun protection control allows flexible adjustment of the parameters for each rental area and individual operation via bus-compatible local buttons.
