Erwin-Piscator-Haus

in Marburg

Project description

The city invested around 43 million euros in the modernisation of the building. The redesign of the Erwin Piscator House in the centre of Marburg was to significantly exceed the requirements of the current Energy Saving Ordinance in terms of building physics. The client - the University City of Marburg - wants to ensure sustainable and future-proof operation. One component for achieving this goal is the installation of energy-saving distribution systems for heating and cooling. The Roth systems installed are customised solutions for temperature control of the respective parts of the cultural building.

The Roth Isocore Basic concrete core temperature control system was used for the foyer and takes into account the special load requirements at all times of the year. The specialist company Bahn Flächenheizungen from Hattersheim installed around 1,300 square metres of Isocore. This means that around 10,000 metres of Roth Duopex S5 system pipe, 20 millimetres, have been laid in the Erwin Piscator House. The concrete core temperature control system covers the basic cooling load in summer operation. Peak loads to maintain the room temperature are compensated by the ventilation and air-conditioning system. The control takes place depending on the outside temperature when the specified limit value is exceeded.

 

Around 1,700 square metres of Roth Flipfix Tacker System were used for surface temperature control in the theatre hall, cloakroom, theatre and evening box office, car park, warehouse, foyer, activity rooms, shop and guest room. It is suitable for use in areas with on-site insulation such as EPS and PU materials as well as mineral insulation materials. The system consists of the Roth Flipfix panel, the Roth Original Tacker Klips with pipe lifting function and the Roth System Pipes. On the construction site, the Flipfix panel is simply unfolded and is laid in a short time without waste. The zig-zag fold ensures practical alignment of the individual panels against each other. The butt joints are joined with adhesive tape - this quickly creates a closed insulation layer surface.

The installation was carried out by Büürma Haustechnik from Gleichen. The system ideally complements the concrete core temperature control in the overall concept of the Erwin Piscator House. The theatre hall also has a room ventilation system. The heat is supplied by the local heating system of the municipal utility company, cooling is provided by a refrigeration system as a chiller and a brine/water heat pump.

Energy efficiency and cost-effective operation

The Roth Isocore Basic concrete core temperature control system uses the solid components of the building structure, such as concrete ceilings and walls, as thermal storage for year-round building temperature control in heating and cooling. For this purpose, the water-carrying pipe system is integrated directly into the concrete components during the shell construction phase. Various Roth system solutions allow the pipe registers to be positioned in the thermally activated building component according to the specific requirements of the building and the desired use and mode of operation. In particular, public buildings with large building storage masses, such as the Erwin Piscator House, are ideally suited for the system solution. Low system temperatures in heating mode and relatively high cooling water temperatures in summer mode allow the integration of regenerative energy generators such as solar and heat pump systems and thus an energy-efficient and cost-effective mode of operation.

Comprehensive planning and consulting service

The Roth range includes coordinated system solutions for construction processes with in-situ concrete as well as specially designed solutions for industrially prefabricated concrete components. The Buchenau-based manufacturer also offers fast-reacting system solutions with pipe arrangements close to the surface.

Roth facilitates a comprehensive planning and consulting service with specially adapted and standard-compliant software planning tools. In addition, Roth provides construction site briefings, object-specific acceptance tests and tested, standard-compliant system performance data. Variable installation techniques can be used to implement individual system solutions tailored to project requirements. Various concepts for hydraulic integration into the building's overall system technology are possible. The manufacturer has many years of practical experience in the planning and supervision of large-scale projects with concrete core temperature control.

Innovative: Roth System Pipes

Roth System Pipes in proven S5 CoEx technology are used for concrete core temperature control. Thanks to the five-fold coextrusion in one production run, the sandwich material of the Roth Duopex S5 System Pipes ensures optimum adhesion between the pipe layers. The pipes offer maximum resistance due to their mechanical, thermal and chemical properties and thus take into account the harsh construction site requirements of large-scale projects. The EVOH oxygen barrier layer is protected against external influences such as heat and moisture by a polymer and a polyethylene layer. The pipe has the highest resistance to deformation due to punctual mechanical stress. By preventing oxygen exchange, it is particularly durable. Roth System Pipes thus ensure optimum functional reliability in continuous operation. Together with Roth control technology, the user receives an economical radiant heating and cooling system that ensures the best possible use of energy.

The architecture

The architecture of the Erwin Piscator House is based on a clear design concept. A striking building form has emerged from the existing building structure, which is characterised by transparency, generosity and openness. With a light-flooded staircase, high walls of exposed concrete and a roof with a diamond pattern, the building harmonises in a modern way with the surrounding architecture. Located below the historic old town in Marburg's city centre, it is not far from the university campus, university library, cinema building and art gallery. The architectural firm Hess/Talhof/Kusmierz from Munich had won the realisation competition for the redesign of the Erwin Piscator House in 2005. Architect Thomas Hess told the Oberhessische Presse that he had wanted to design a colourful, robust and cosmopolitan building for a colourful and tolerant city. The positive response from the inauguration ceremony in June 2016 showed that he had succeeded.
