    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.

  • Hächler rebuilds Spreitenbacher Waldhütte

    Hächler rebuilds Spreitenbacher Waldhütte

    Hächler AG from Wettingen has rebuilt the forest hut belonging to the municipality of Spreitenbach, which had become dilapidated due to subsidence. From spring onwards, the forest hut will again be available to citizens for festive occasions with 40 seats, according to the press release . There is a new hall with a fitted kitchen and an open fireplace both inside and outside.

    The new building in the middle of the forest on Heitersberg became necessary because of subsidence. The forest hut was built in 1968 and renovated in 1990. According to the Hächler Group, the municipality of Spreitenbach decided to rebuild the popular forest hut due to the subsidence of the ground by around 20 centimeters. In May 2020, the timber construction department at Hächler AG was awarded the contract to build the new forest hut.

    According to a report submitted by Günter Ebner, Head of Timber Construction at Hächler, the replacement building in timber element construction in the Neuenhof workshop was prefabricated in the same dimensions as the old hut. The finished wall elements with built-in electrical preparation and cutting of the roof components were produced in just three weeks. The shell assembly in the forest on the Heitersberg was carried out with millimeter precision using the company's own truck crane. The inner wall surfaces made of multi-layer panels in spruce and fir were protected from moisture during assembly. According to the Hächler report, only ecological and sustainable building materials were used.

    The materials are technically state-of-the-art and enable a comfortable room climate as well as heat, cold and noise protection. The combination of vapor-permeable and multi-layer materials with good soundproofing properties would have made this concept of the forest hut a really great project, construction manager Ebner is quoted as saying.

    21 cubic meters of domestic spruce wood, 45 cubic meters of mineral insulation and 450 square meters of multilayer wood panels were used for the supporting structure.
