  • Zurich agglomeration needs new buildings

    Zurich agglomeration needs new buildings

    The Zurich agglomeration is the only one in Switzerland where the population is growing faster than the housing stock. This was revealed by a study conducted by the Zurich research institute Sotomo on behalf of Fürschi Züri.

    The housing stock in the Lausanne conurbation has grown by 10.0 per cent since 2016, in Geneva by 8.9 per cent and even in Winterthur by 8.5 per cent. In Zurich, the figure was only 7.8 per cent. Within the Zurich agglomeration, the labour market region of Kloten saw above-average growth of 10.9 percent, Uster-Dübendorf 8.6 percent and Limmattal 8.4 percent.

    The agglomeration is lagging behind, particularly in terms of new builds, with growth of 3.8 per cent. Only the Basel agglomeration is lower at 2.7 per cent. Lausanne has 5.5 per cent more new builds and Winterthur 5.3 per cent.

    Zurich, on the other hand, is ahead with an increase of 4.5 per cent in replacement new builds. However, Zurich is also the agglomeration in which replacement new builds create the lowest number of new flats with a factor of 2.8 and the smallest new living space with a factor of 3.4. Even Winterthur achieves a factor of 3.4 for the number of flats and 3.7 for floor space. Lausanne leads the field with a factor of 6.5 for the number of apartments and 5.9 for floor space, followed by Geneva with 6.1 for the number of apartments and 5.6 for floor space.

    There are considerable differences within the Zurich agglomeration. The labour market region of Kloten has a factor of 4.3 for the number of flats. The fewest new flats are being created in Küsnacht-Meilen with a factor of 2.2. In the city of Zurich, the factor for the number of flats is 2.3.

    Young people and families are the main direct beneficiaries of new builds. The majority of residents of new builds come from the municipality (Zurich agglomeration 41 per cent, Winterthur 50 per cent) or from the agglomeration (Zurich 39 per cent, Winterthur 11 per cent). Newcomers from abroad mainly move into existing flats; in the agglomeration, they make up 23 per cent of all newcomers to existing flats.

    Completely renovated flats are generally more expensive than new builds. Newly occupied existing flats in sought-after locations are just as expensive as new builds, and even more expensive in Geneva. New builds do not drive up the prices of neighbouring existing flats either.

    The Zurich conurbation is dependent on new construction, concludes study author Michael Hermann. “New buildings are the key to ensuring that Zurich remains an attractive place to live for everyone,” he is quoted as saying in a press release from Fürschi Züri.

    “Blocking renovations and new builds is counterproductive,” adds Raphaël Tschanz, Director of the Zurich Chamber of Commerce(ZHK). “Without new builds, young adults and families will be displaced.”

    Fürschi Züri is an initiative of the ZHK and like-minded organisations and individuals.

  • Sustainable construction projects launched in Germany and abroad

    Sustainable construction projects launched in Germany and abroad

    Implenia, the construction and property company based in the Glattpark district of Opfikon, has won several tenders for building construction contracts. According to a press release, the contracts have a total volume of 160 million Swiss francs.

    The company will construct the new office building of the Swiss National Science Foundation(SNSF) in Bern. The sustainable building will be constructed using local timber and recycled concrete in accordance with the Swiss Sustainable Building Standard (SNBS). Implenia has also been awarded several contracts in Germany.

    In Mainz, Implenia, together with its partners Gemünden and Apleona, was awarded the contract to construct a new 10,000 square metre research building for TRON. The research institute develops new diagnostics and active ingredients for immunotherapeutic treatments.

    In Leipzig, Implenia and its partner GP Günter Papenburg AG are building a seven- to eight-storey residential development on nine connected properties. In addition to 202 residential units, many commercial and ancillary premises are to be built. The buildings will be constructed as low-energy buildings in accordance with the Efficiency House 55 standard and the entire complex will be handed over on a turnkey basis.

    Three residential buildings with 101 units are being built in Munich, which should be ready for handover by 2026. Implenia will also realise a further stage of an ongoing project in Heilbronn and has been commissioned with a pre-construction phase in Siegburg.

  • Sursee makes solar systems and green roofs standard

    Sursee makes solar systems and green roofs standard

    In future, the roofs of new buildings or roof renovations in the municipality of Sursee are to be fitted with solar panels. For flat roofs, the aim is also to green them. This was decided by the Sursee municipal council on 14 October with the majority approval of a counter-proposal to the municipal initiative for an independent and ecological energy supply (solar initiative). The initiative committee had withdrawn the solar initiative after the city council had drafted the counter-proposal.

    The counter-proposal is in line with the new cantonal energy law, which will come into force on 1 March 2025, subject to a referendum. New buildings will then have to be equipped with 60 per cent solar panels, and 30 per cent for roof renovations. If the requirements are not met, a replacement levy of CHF 1,000 per kilowatt will be due. In deviation from cantonal law, this levy will only be possible in Sursee if the construction and operation of the solar system is economically unreasonable.

    The new cantonal energy law does not specify any requirements for the greening of roofs. However, Sursee wants to use green roofs to improve the urban climate and as a substitute habitat for plants and animals. For this reason, a combination of green roofs and solar panels is being sought as standard on flat roofs.

    The solar utilisation of façades called for in the solar initiative is not provided for in the counter-proposal. The city council feared that this would have a negative impact on the townscape. In addition, the cost-benefit ratio of façade systems is currently even worse than that of roof systems.

  • Catalog recommends materials against urban heat islands

    Catalog recommends materials against urban heat islands

    The federal government has presented a reference work for new buildings and buildings to be renovated that shows the effect of building materials on the heat in urban and densely populated areas. It was created by the University of Applied Sciences Northwestern Switzerland on behalf of the Federal Office for Housing ( BWO ).

    According to a media release by the BWO, the catalog compares materials for outdoor use such as floor coverings and facades and explains their effect on the outside temperature. It also takes into account other properties of the materials, such as how they reflect sunlight or how much water floor coverings allow to seep away.

    The BWO calls on planners, developers and house owners to consult this material catalog when choosing suitable materials. In addition, the Office invites the scientific community to further develop and research the topic. Because according to the latest climate scenarios, the average temperatures in Switzerland will be 2.5 to 4.5 degrees higher by 2060 than in the period from 1981 to 2010. This means that the buildings that are being built or renovated today will be the microclimate of tomorrow shape.

  • The best sustainable house is in Switzerland

    The best sustainable house is in Switzerland

    This year's Häuser Award had the motto The best sustainable houses, explains the magazine “Häuser” in a message . In addition to new buildings, conversions and extensions were expressly included. With regard to the properties, the jury of the houses award primarily examined the handling of the land, the energy concept, the choice of materials, the construction methods and the technologies used.

    The small house in Jonschwil designed by Lukas Lehnherr was able to qualify as the winner. "With the renovation of a coach house, the architect Lenherr succeeded in squaring the circle," the message quoted from the jury's reasoning for the decision. “An amazingly spacious house was built on a tiny area that fits perfectly into the townscape.” Architect Lehnherr from Quinten SG can look forward to the prize money of 7,000 euros associated with the award. The builders will receive a further 1000 euros from the cooperation partner of the award, the Association of Private Builders eV

    The jury awarded second prize to the extension of a Munich town house by architect Anton Mang. The third prize went to the Binnewies house in Münsterland. The expansion of a farm in the Taunus was honored with the award for outstanding interior design. The Green Dwelling near Hanover won the readers' award in 2021 decided by the magazine's readers.
