  • Juch site to become a beacon of circular construction

    Juch site to become a beacon of circular construction

    Graber Pulver Architekten AG from Zurich has won the architectural competition of the City of Zurich for the planned new building of the recycling centre Juch-Areal of Entsorgung + Recycling Zürich(ERZ) in Zurich-Altstetten. With the new building, the Zurich Office for Structural Engineering and the ERZ want to create a pioneering project in the recycling of building components, according to a media release.

    According to the statement, they want to “explore to the maximum the possibilities of reusing building components and the potential of the circular construction industry in public buildings”. For this reason, the submitted competition projects should feature as high a proportion of reused components as possible.

    For example, most of the building material for the winning project came from the immediate vicinity of Zurich. Used reinforced concrete slabs are used in the operations building and the hall floor. The walls consist of wooden frame constructions insulated with old books, magazines and clothes. Discarded scaffolding will be repurposed as storage shelves. The existing hall structure is to be rebuilt only slightly adapted.

    The façades will be protected from the weather by panels of recycled glass and aluminium as well as old kitchen covers, doors and table tops. The greening of the façades will provide a habitat for plants and animals and ensure local heat reduction.

    By using old building components, the city of Zurich saves almost 600 tonnes of carbon dioxide compared to a conventional new building. This corresponds to a 40 per cent reduction in greenhouse gases.

    Second place went to Studio Hammer from Basel. Third place went to the Zurich-based consortium Studio Burkhardt and Lucas Michael Architektur.

  • Hardau I is being rebuilt for 71 million francs

    Hardau I is being rebuilt for 71 million francs

    The aging Hardau I housing estate is located between Hardstrasse and the striking residential towers of Hardau II. It has existed since 1964 and was designed by the architect Eberhard Eidenbenz. Today’s 80 apartments are small-scale with a modest standard of fit-out. Noise protection, energy efficiency and accessibility leave a lot to be desired. Since the area has potential to be used and more family apartments can be built as a result, the City of Zurich has decided to replace it.

    In 2018, the Office for Buildings of the City of Zurich selected the winning project by means of an architecture competition: Graber Pulver Architekten AG won over the jury with their “Laurel & Hardy” project. Two structures of different shapes and heights are planned. The six-storey courtyard building is clearly separated from the Hardau park. A seven-storey building block complements the existing block edge along Hardstrasse. Most of the apartments in the courtyard are oriented on three sides.

    122 predominantly spacious rental apartments are planned for residents with low to medium incomes. Single rooms, studios and music practice rooms can be rented individually. Areas for services and a personal registration office are also being built along Hardstrasse on the ground floor. In addition, a kindergarten, studios and a youth shop of the Open Youth Work Zurich (OJA) are planned at Hardaupark. Together with the existing Hardau high-rises, which mostly comprise smaller apartments, a well-mixed urban housing supply is to be created.

    At Hardau I, energy parameters of the Minergie-P standard in the sense of the 2000-watt society have top priority: Nevertheless, only the construction on the noise-polluted Hardstrasse is certified according to the Minergie-P-Eco standard. Because no controlled ventilation is installed in the quieter courtyard building. The mobility concept provides for a neighborhood with little cars: The number of parking spaces will be significantly reduced to 31 instead of the previous 249. Energy is generated directly on the property by a photovoltaic system planned and financed by the city of Zurich’s electricity company. So that the electricity produced on the roofs of the property can be used on site, tenants and property developers form a self-consumption community.
