Green: house
The green: house is a “ wood-concrete experimental building” built in 2010 on the site of the Bauhaus University Weimar . The building was created as an element to expand the campus under the direction of Walter Stamm-Teske . In addition to the Faculty of Architecture and its "Design and Housing" chair, other partners were also involved in this project.
history
The green: house was developed by Walter Stamm-Teske from the Professorship of Design and Housing as part of the bauhaus.EXPO 09 initiative for the 90th anniversary of the Bauhaus since 2009. The project initiative, which consists of four professorships from the Faculty of Architecture, is dedicated to a future campus expansion of the Bauhaus University Weimar in different partner constellations and on the basis of different building materials. The urban master plan by AV1 Architekten from 1996 formed the basis of the building and pavilion concepts that were created for this previously largely unused campus area. The project group defined the 13 solitary buildings proposed here, which were derived from the dimension and volumetry of the neighborhood context four “experimental fields” for prototypical research applications, which are to be designed and implemented in close cooperation with the teaching formats of the Faculty of Architecture. The overriding aim of all projects of the initiative was to revitalize the applied research in the portfolio of the Faculty of Architecture and to break new ground with exemplary solutions in the choice of materials, project cooperation, construction, use and standards that represent sustainable alternatives for building in the 21st century.
The green: house has been implemented as a model project made of wood-concrete at the Bauhaus University Weimar since autumn 2010 . The prototypical project approach does not only lie in the use of the new building material itself, but also in the process. With 20 industrial partners, companies and specialist planners who, on the one hand, conveyed know-how, on the other hand, effectively enabled the completion of the building with products, the experimental housing served as a test room for new products, component details, standards and combinations of trades that are usually strictly separated in the construction process.
Prototype material application
In cooperation with Helika GmbH , Reutlingen, Walter Stamm-Teske experimented with a new type of building material, " wood concrete ", for one of these fields of experimentation , which promises a sustainable alternative to prefabricated construction methods in terms of both building physics and the production process. The building material is made exclusively from wood chips and cement as a binding agent. In combination with the timber frame construction known from prefabricated house construction , there are building physical properties that are competitive with solid constructions . A project goal of the research partners with the 1: 1 application of the material in the experimental building green: house is accordingly the approximation of the product properties to those of a solid construction material with simultaneous processing possibility with established wood production technology. In addition to the advantage of an efficient production process and quick and easy installation, the selected wall structure offers favorable thermal and acoustic reference values. A market value for the future can be assumed here, particularly in connection with the energetic consideration. The project is funded as a research project of the AiF (Allianz Industrieforschung), which shows the national and international interest in wood-concrete research.
Architecture education
The project was accompanied by lectures and represents a future format for the Faculty of Architecture, in the sense of a 1: 1 teaching. In total, over 50 Bachelor and Master students from the Faculty of Architecture contributed to the planning and implementation of the green: houses. In addition to participating in the real project process, there were regular visits to construction sites for students of architecture and civil engineering. The building was planned according to the criteria of the passive house standard and from the winter semester 2011/12 will contain 50 workplaces for students and employees of the architecture faculty. With the expected monitoring results of the building, a first future energy standard for university buildings on the Weimar campus is to be defined. At the same time, a holistic, objective energetic analysis should take place through the green: house project network and processed systems should be tested for their sustainability.
Project overview
Building / construction
The main components of the building were made from a material that is new in this application. Under the name “ wood concrete ”, 8 cm thick and 1.25 m × 1.25 m large building panels were joined on an insulated wooden frame construction to form a total of 26 large-format building elements. In just 6 days of construction, the shell could be erected using the prefabricated components. The wood-concrete construction could be used directly as a plaster base.
Openings / windows
All openings in the building were designed as triple glazing. Except for the necessary openings for the entrance and the 2nd escape route (gable ends), the windows have been implemented as fixed glazing without a frame in order to keep thermal losses as low as possible. In the window layers affected by direct sunlight, sun protection was also installed in the space between the glass. A skylight above the central staircase ensures that daylight is used well inside.
ventilation
In order to achieve the passive house standard or zero-energy house standard, a controlled ventilation system was installed. In addition, a geothermal heat collector was implemented below the floor slab, which ensures that the outside air is pretempered in both heating and cooling. The exhaust air is extracted in the sanitary / kitchen area, the supply air is blown in in the area of the workplaces.
heater
Mathematically, no additional heating is required for the building, i. H. The building is generally heated by the heat generated by the people and devices present (passive house). To protect against extreme cold spells, underfloor heating was integrated in both the floor slab and the ceiling screeds. The supply comes from surplus energy from a neighboring building (digital lab).
Power supply
The flexible use of the rooms from individual workstations to group workstations to exhibition purposes requires an equally flexible concept for the power supply. Therefore, a concentration of the power distributing components was made. Only the central room layers serve as a distributor via socket cornices in the ceiling area. The feed to the individual power consumers is carried out via a hook system that is visible on the ceiling and a correspondingly open and designed cable routing.
Solar modules / solar collectors
The training as a flat roof combined with an over-high parapet offers possibilities for the positioning of solar modules and solar collectors . The aim is to achieve the zero-energy house standard with the help of these components.
