oms of the three penthouses on the roof are glazed room-high on two sides, thus offering a panoramic view on the canal, the Spinnereipark and the mountains. Broad roof terraces extend the interior to the outside.
Energy supply and ventilation
The energy supply for the building is being operated from the technical room on the ground floor. Regarding the heat supply system, a weather-compensated pellet boiler system with an external earth tank was selected. The individual heating circuits (floor heating, water heating) are supplied centrally by the technical center. The distribution of the heat takes place as a floor heating system with individual room control. In order to ensure a flexible usage of the apartment layouts, the distribution of the heating circuits is kept as small as possible. The hot water supply is controlled via a fresh water station with buffer storage.
The consumption is determined by means of a heat quantity detection per unit. The primary energy requirement undercuts the energy saving regulations (EnEV) 2009 by 30%, which was valid at the time of planning, while the transmission heat loss is around 15%. This fulfills the requirements of the KfW-70 standard and complies the requirements of the Renewable Energies Heat Act (EEWärmeG).
Due to the DIN-Standard 1946 regarding ventilation technology, the ventilation concept implies the installation of a ventilation system for each individual residential unit. It consist of a central ventilation system with heat recovery, located in the lavatories or storage rooms of each unit. The distribution of air takes place via floor channels or via the suspended ceilings. The overflowing air is being aspirated in the baths and transported to the outside, passing a heat exchanger. The heat recovery rate is 70%. The continuous exchange of the room air results in an improved protection against structural damage (such as mold). The basement rooms receive a temperature- and humidity-controlled room aeration. The underground car park is ventilated via shafts and the paled gate.

Curriculum studio / partecipanteThe Stuttgart-based practice known today as Behnisch Architekten was founded in 1989 under the leadership of Stefan Behnisch. Originally established as a branch office of Günter Behnisch’s practice Behnisch & Partner, it became independent in 1991 and has subsequently developed into an international practice with offices in Stuttgart, Munich, Los Angeles/California (1999 – 2011), and Boston/Massachusetts. These offices are directed by Stefan Behnisch and his partners Robert Hösle (Munich), Robert Matthew Noblett (Boston) and Stefan Rappold (Stuttgart). Stefan Behnisch is involved in all three offices.
From the outset, the social dimension of architecture has been a fundamental aspect of the firm’s design philosophy. The search for innovative and sustainable solutions making optimum use of natural resources has produced a rich variety of buildings, each of which responds to specific user requirements and site conditions.
