  • Wood City – a milestone for the cities of the future with wood

    Wood City – a milestone for the cities of the future with wood

    The renaissance of timber construction as a symbol of ecological building
    The decision to use wood as the primary building material is at the centre of Stockholm Wood City. This step reflects the growing awareness of environmentally friendly construction methods and emphasises the many advantages of timber constructions. In addition to enhancing the aesthetics of the urban space, timber buildings help to improve air quality, promote well-being, increase labour productivity and act as a natural carbon sink.

    “Stockholm Wood City is a manifesto of our vision for the future,” explains Annica Ånäs, CEO of Atrium Ljungberg. “The project not only marks a significant step forward for our company, but also sets a historic milestone for Sweden’s innovative strength.”

    Innovation and sustainability as guiding principles
    Stockholm Wood City goes beyond the mere use of wood as a building material and takes a holistic approach to sustainability. The project integrates advanced technologies to increase energy efficiency and promotes the careful use of resources through the self-production and shared use of energy as well as the use of resource-efficient construction techniques.

    As a flagship project for future-orientated urban development, Stockholm Wood City will not only enrich the cityscape of Stockholm, but will also provide significant impetus for the construction industry worldwide. With its fusion of innovation, sustainability and community spirit, it offers an inspiring blueprint for the design of future urban living spaces.

    Implenia and Empa join forces for CO2-negative building materials

    As Empa ‘s realisation partner,Implenia is building the Beyond Zero Unit in Empa’s NEST building in Dübendorf, the construction and real estate company based in the Glattpark district of Opfikon announced in a press release. The new unit will be used for research into CO2-reduced and CO2-neutral building materials. The Beyond Zero Unit will be integrated into the middle level of the NEST research and innovation platform.

    “We are delighted that Implenia is able to enrich the great research and innovation platform NEST with a new unit as a partner,” said Jens Vollmar, Head Division Buildings at Implenia, in the press release. “As a leading Swiss construction and real estate service provider, we are thus jointly providing important insights for the future, CO2-reducing construction and operation of buildings and infrastructure.” Implenia intends to use the knowledge gained from the Beyond Zero Unit for its own developments and planning.

    The new unit in the NEST building is not the company’s first collaboration with the research institute. “Implenia has realised pioneering sustainable buildings on the Empa Campus in Dübendorf, most recently a laboratory and office building and the first car park in hybrid timber construction in Switzerland,” explains Empa Director Tanja Zimmermann. “The fact that Empa and Implenia are also working together in research into innovative building materials with this new partnership and are investigating promising applications over a longer period of time on our NEST platform promotes the direct transfer of sustainable innovation into practice.”

  • Wooden buildings get CO2 certificates

    Wooden buildings get CO2 certificates

    The Swiss competence center Timber Finance Initiative and the Seattle, Washington-based company for construction technology, real estate development and fund management, Green Canopy NODE , are working together with the Zurich-based project developer South Pole and the consulting firm Gordian Knot Strategies from Portland, Oregon the development of a methodology for issuing CO2 certificates for wooden buildings, the partners inform in a communication . In concrete terms, the methodology should make it possible to measure the carbon stored in timber construction and monetize it via CO2 certificates. As a result, wooden buildings could be recognized as a negative emission technology and wood could be established as a low-emission building material.

    The globally recognized program for awarding so-called carbon credits, Verified Carbon Standard , will serve as the standard for the globally applicable methodology. "The UN Climate Change Council has recently officially recognized the storage potential and benefits of wood," Thomas Fedrizzi, co-founder of the Timber Finance Initiative, is quoted as saying in the release. "Wood is not only a carbon sink, but as a building material it also achieves emission reductions by replacing emission-intensive building materials."

    As a renewable, low-emission alternative to concrete and steel, wood can protect the environment twice, according to the statement. On the one hand, by trees removing CO2 from the atmosphere and on the other hand, by timber storing the carbon in buildings in the long term. "Houses made of solid wood are more durable and can be less expensive," explains Aaron Fairchild, co-CEO of Green Canopy NODE. "This makes climate-friendly houses accessible to people of all income levels."

  • Daiwa House Modular Europe names four trends that will be essential for the real estate industry in 2022

    Daiwa House Modular Europe names four trends that will be essential for the real estate industry in 2022

    Global scarcity of resources
    The prices of many building materials are currently skyrocketing. This will not change this year either – insulating materials, steel, everything will become more expensive and scarce. Construction prices are rising accordingly and threaten to make many projects unprofitable. In addition, the emerging countries in particular are currently asking for a lot of material and are buying the market empty. So the situation will continue to worsen. In the long term, only improved project planning with a greater focus on reusability can help, because circular economy and resource protection already begin in the planning phase. If entire buildings, parts of buildings and building materials can be recycled or found a subsequent use, this not only reduces the material requirement, but also contributes to greater sustainability at the same time. It is important to think big about Cradle to Cradle in the future.

    Sustainability not only through energy savings in the usage phase
    The German construction industry in particular has an urgent need to catch up when it comes to sustainability. In the Netherlands there is already a CO 2 cap per square meter of new construction. With the new government with green participation, it is quite conceivable that such a cap will also become the new guideline in Germany. In addition, disposal costs will remain a major issue and will increase proportionately. Due to the still immature framework conditions for recycling processes and the low landfill capacities, waste is becoming a further driver of construction costs. This shows how important it will be in the future to use building materials and building parts for a long time and to reuse them later – as is already possible in modular construction by refurbishing reused modules. The circular economy should therefore be the focus of the project early on in the planning.

    Digitization and AI also in construction
    In order to increase sustainability across the entire industry and to counteract the scarcity of resources, both planning and production must be optimized. Both must become more intelligent overall and network. The use of “artificial intelligence” is ideal for this. It supports construction projects, for example, through generative design, proactive problem detection and the avoidance of delays and cost overruns. But it also has to be used in production. An example: Digitizing the cut leads to less offcuts and waste. Thanks to good advance planning and the use of an AI, the remaining material from a cut can be used for further use in other future projects. This not only saves material, but also additional work steps and thus increases the efficiency of the entire production process. After all, residual materials are also resources.

    Industrialized manufacturing as in the automotive industry
    The advance of digitization within the construction industry also enables the use of semi- or fully automated processes. They reduce sources of error and make production more efficient. Affordable living space can be optimally realized with robot-supported construction processes in connection with the necessary digital management of the construction data – from planning to construction site. In view of the acute shortage of skilled workers, which will not be solved in the next few years, this development is the logical consequence. Daiwa House Modular Europe will also rely on automated processes in the already planned German gigafactory.

    These four trends should encourage the construction industry to rethink. In addition, there are a number of other changes such as a generational change in the ranks of managers as well as political and social change. Builders are now open to standardized building solutions. Modularly planned and built buildings offer a short construction time and high quality thanks to around 90 percent prefabrication in the factory. In the residential, care, hotel and education segments in particular, there are similar needs despite the different locations – so not every building has to be a prototype.

  • Coconut fiber becomes a building material

    Coconut fiber becomes a building material

    As early as 2014, the Institute for Materials and Wood Technology (IWH) at the Bern University of Applied Sciences (BFH) started a research project in which inexpensive and sustainable building material based on coconut fibers was to be developed, the BFH informed in a message . The experience gained is being further developed by Michail Kyriazopoulos in a spin-off from the BFH. The former student and research assistant at the IWH founded the start-up NaturLoop together with Daniel Dinizo.

    As the first product, NaturLoop has launched a building board made from coconut fibers. Crop waste from Filipino coconut farmers is used for their production. "With Cocoboard we offer a sustainable, cheap and local alternative to conventional building materials", Kyriazopoulos is quoted in the communication. The next thing on the NaturLoop program is the opening of a production facility in the Philippines.

    The products of the young company from Bern are intended to reduce the Philippines' dependence on imported building materials. The sale of coconut fibers also offers local coconut farmers an additional source of income. "As a technology service provider, we want to offer complete solutions for the development of sustainable, natural biocomposites made from agricultural by-products," says NaturLoop CEO Dinizio. For him, sustainability means "taking into account the mutual dependence of nature and people."

  • Porta Samedan is built with recycled building material

    Porta Samedan is built with recycled building material

    The new Porta Samedan shopping center is being realized by Migros Ostschweiz and Pfister Immobilien AG . During these days, the concreting of the floors of the new building is taking place, according to a media release . When it comes to building materials, the partners rely on the circular economy. Recycled products are used for both concrete and cement.

    The one main component in concrete is cement. This comes by train from the Holcim plant in Untervaz GR to the Upper Engadin, where Montebello produces the recycled concrete on site. The Holcim product Susteno is used. According to the information, this is the only resource-saving cement in Europe in which the fine proportion of mixed granulate from demolished buildings is used as an additive, which cannot be used in concrete production. Holcim can completely close the building material cycle with Susteno, as this material would otherwise have to be dumped.

    The other main component in concrete are the aggregates. "Here we rely on recycling: instead of natural gravel, we use demolition material from the region," explains Flurin Wieser from the Engadin construction company Montebello.

    "The Porta Samedan development shows that the building materials industry, with innovative products and solutions, is playing an increasingly important role in the transition to the circular economy and is making a significant contribution to a sustainably built future," said Philippe Rey, Head of Cement Sales German-speaking Switzerland at Holcim Switzerland.

    Porta Samedan is scheduled for completion in 2021. Among other things, it will house the first Migros supermarket in the Engadine.
