  • Opening of the “STEP2” NEST unit

    Opening of the “STEP2” NEST unit

    On 29 August 2024, the latest building module “STEP2” was officially opened in Empa’s NEST research and innovation building. This two-storey module in the south-east of NEST brings together a large number of innovations, all of which are aimed at significantly reducing material and energy consumption in the construction industry and promoting resource-saving construction methods.

    In Switzerland, the construction sector is responsible for the majority of raw material consumption, waste generation and a third of CO2 emissions. With the NEST building, Empa, together with over 150 partners, is pursuing the goal of developing new technologies and materials to the point where they are ready for the market. The “STEP2” unit is the latest example of how this vision is being turned into reality.

    From the digital staircase to the adaptive façade
    When you enter the “STEP2” unit, the innovative ribbed filigree ceiling immediately catches the eye. This was developed by an interdisciplinary team and enables spans of up to 14 metres, ideal for office and high-rise construction. Thanks to digital planning methods and 3D-printed formwork, it was possible to reduce the amount of material used by 40% without compromising on stability. The ceiling also fulfils important functions in terms of room acoustics and as a thermal storage mass.

    Another technological masterpiece is the curved “Cadenza” concrete staircase, which forms the centrepiece of the building. It was realised using computer-aided design and 3D printing technologies, which enabled an extremely material-efficient construction method. This staircase is an impressive example of how digital manufacturing technologies can contribute to innovative and sustainable design solutions in the construction industry.

    Holistic energy concept and innovative materials
    The “STEP2” unit is based on an integrated energy and comfort concept that was developed in collaboration with leading engineers. The innovative double skin façade, which is equipped with modern shading technology and controlled natural ventilation, plays a central role in the building’s energy efficiency. This façade also serves as a test platform so that new technologies can be easily integrated in the future.

    STEP2″ also focusses on innovation and sustainability when it comes to the materials used. For example, wall and floor panels were made from recycled waste materials such as denim fibres, paper cups and coffee grounds. These materials not only reduce the need for new raw materials, but also help to reduce greenhouse gas emissions.

    Co-creation and market readiness
    The “STEP2” unit was developed using a co-creation approach in which all partners involved worked closely together from the outset. This approach made it possible to develop marketable solutions that have a real future in the construction industry. For BASF, the main partner in the project, “STEP2” provides the ideal environment to translate its chemical expertise into concrete, sustainable construction solutions.

    “STEP2” is more than just a building module – it is a real innovation environment that demonstrates how research and industry can successfully work together to bring sustainable technologies to market. In future, the unit will serve as a workplace and innovation workshop to achieve further progress in sustainable construction.

  • New white paper: ‘Energy storage systems for properties: Using renewable energy efficiently’

    New white paper: ‘Energy storage systems for properties: Using renewable energy efficiently’

    Link to the whitepaper

    Switzerland is aiming for a target of net zero by 2050. This means replacing fossil-based energies with renewables. However, the output from systems is dependent on weather conditions, the time of day, and the season. Getting supply and demand in sync calls for storage solutions. This also improves the property’s carbon footprint, because it requires less oil or gas to cover peak loads.

    Electricity storage systems: battery-powered flexibility
    Battery storage systems can temporarily store surplus solar power locally and supply household consumers, electric vehicles or the heat pump later on. This significantly increases the level of self-consumption and with it the cost-efficiency of solar power plants. Not only the operator benefits from a storage system – the electricity grid does as well. This means, for example, that when a solar power plant produces a surplus, it doesn’t have to be shut off for fear of overloading the grid. And in the reverse scenario – when demand outstrips supply – locally stored energy can help cover peak loads, which stabilises the grid and keeps costs low. Currently the standard means of electricity storage is the lithium-ion battery, while alternatives such as sodium-ion batteries and salt batteries have yet to become established. This also applies to bidirectional charging, in which the battery of an electric vehicle is used for local electricity storage.

    Heat storage units: geothermal probes and containers
    One alternative to storing surplus solar power is to transform it into thermal energy. Heat can be stored over weeks or months and used later for heating and hot water supply as required. This makes heat storage a great fit with renewable heating systems such as heat pumps and thermal networks. And some types of storage system can be used as heat sinks in summer to cool buildings with minimal use of energy. The most common storage types in Switzerland are geothermal heat storage units and container heat storage units. One interesting variant that requires less space is ice storage.

    Hydrogen and methane: seasonal storage
    Another way to store surplus solar power seasonally is to transform it into a carbon-neutral gas like hydrogen or methane (‘power-to-gas’). If required, the gas can be used either to produce heat and electricity or as a fuel for vehicles. Hydrogen is produced through the electrolysis of water, and the degree of efficiency in this transformation is up to 80 per cent. Transforming it further into methane has the advantage that it can be stored in the natural gas grid, so it doesn’t require separate infrastructure. The overall degree of efficiency depends on the method used, but with a current best-case result of 50 to 70 per cent, it is not yet cost-effective.

    You can find much more information and real-life examples in the new ewz white paper ‘Energy storage systems for properties: Using renewable energy efficiently’.

  • Population supports sustainable electricity production

    Population supports sustainable electricity production

    On 18 August, the voters of Spiringen clearly approved the Sidenplangg solar installation with 68.8 percent. The voter turnout was 55.3 per cent. With their approval, the voters have seized a great opportunity and shown that they are in favour of sustainable electricity production, writes the municipal council in a press release.

    EWA-energieUri is also delighted with the yes vote. He is “grateful that the people of Spiringen are so clearly in favour of our project”, Werner Jauch, CEO of the Uri-based energy producer, is quoted as saying in a separate press release. As the landowner, the Uri Corporation must now approve the project. The planning application can then be submitted.

    The plant is to be built in the Schächental valley on 12 hectares at an altitude of 1,800 to 2,000 metres above sea level in an area that is already used for avalanche barriers. With a capacity of 8 megawatts, around 12.5 gigawatt hours are to be generated annually, up to 45 per cent of which in winter. The investment amounts to around CHF 39 million. The first part of the plant is due to be connected to the grid at the end of 2025.

    In addition to EWA-energieUri and the municipality, aventron AG, a joint venture of Swiss regional utilities based in Münchenstein BL, is also involved in the project.

  • Fresh capital for the decarbonisation of real estate

    Fresh capital for the decarbonisation of real estate

    The software service provider Optiml has secured fresh capital totalling USD 4 million in a pre-seed financing round. According to a press release published on LinkedIn, the company intends to continue supporting the property market with software as it takes steps towards decarbonisation in the sector. As a service provider (Software-as-a-Service/SaaS), Optiml wants to develop programmes that facilitate data management and provide tools for asset and portfolio decisions. In doing so, the company takes into account constantly changing regulations and market conditions, according to the press release. With software supported by artificial intelligence, property companies and owners can plan their refurbishment and renovation work in line with the market and incorporate decarbonisation targets for their properties.

    The refurbishment and decarbonisation software from the spin-off of the Swiss Federal Institute of Technologyin Zurich(ETH), which was founded in 2022, is based on years of research in the ETH Sustainability and Technology Group (SusTec). It uses science-based optimisation algorithms.

  • Canton of Zurich wants to make solar systems mandatory on large roofs

    Canton of Zurich wants to make solar systems mandatory on large roofs

    “To ensure a secure electricity supply in Switzerland and to achieve the goal of net-zero greenhouse gas emissions, electricity production from local renewable energies must be rapidly and significantly expanded,” says the State Chancellery of the Canton of Zurich in a press release on a planned partial revision of the Energy Act. Specifically, the canton of Zurich wants to make the installation of solar systems on suitable roofs with an area of 300 square metres or more mandatory. The canton estimates that this would allow around 60 per cent of a total annual potential of 6 terawatt hours of solar power from roofs to be exploited.

    The installation of solar systems on large roofs should be mandatory for both new and existing buildings. Existing buildings may be retrofitted when the roof is renovated, but by 2040 at the latest. The requirement should also only apply “if the solar installation is economical over its entire service life”. The corresponding bill has been submitted for consultation until the end of November.

    In addition to the obligation for solar systems, the partial revision provides for the promotion of technologies for seasonal energy storage. This is to be funded by a subsidy fund managed by the electricity grid operators, which will be financed by a levy of a maximum of 0.5 centimes per kilowatt hour of electricity. Competitive tenders are planned, from which projects with the most winter electricity per subsidised franc will benefit, as well as support for seasonal storage technologies that are still under development.

  • Environmentally friendly innovation in the construction industry

    Environmentally friendly innovation in the construction industry

    Griesser is switching to even more sustainable aluminum. Previously, the internationally active developer of sun protection systems for buildings from Aadorf used aluminum that consisted of 64 percent primary raw material and 36 percent recycled aluminum, Griesser explains in a press release. Griesser now uses aluminum that consists of only 35 percent primary raw material. The remaining 65 percent is obtained from scrap or consumer scrap generated during the aluminum production process.

    “Our climate vision envisages complete decarbonization by 2050,” Griesser CEO Urs Neuhauser is quoted as saying in the press release. “In the material area of aluminum, we have the greatest leverage to significantly reduce our CO2 footprint.” The aluminum previously used by Griesser had a footprint of around 4.7 kilograms of CO2 emissions per kilogram of aluminum produced. Switching to the even more sustainable aluminum will reduce this figure by 30 percent to 3.3 kilograms of CO2 per kilogram of aluminum. The press release cites a European average of 6.7 kilograms and a global average of 16.7 kilograms as comparative values.

    Griesser is working with two European suppliers to reduce its footprint. They offer certified low-carbon aluminum. In addition to the use of recycled aluminum, the aluminum is produced in Europe using energy from renewable sources and modern technologies, explains Griesser. Compared to conventional production, the production process therefore has “up to five times” lower CO2 emissions.

  • Rolex invests one billion francs in new giant factory in Bulle

    Rolex invests one billion francs in new giant factory in Bulle

    The world-famous luxury watch manufacturer Rolex is planning a massive expansion in western Switzerland. A gigantic production facility is to be built in Bulle, in the canton of Fribourg, by 2029. Covering an area of 104,000 square metres – the equivalent of almost 15 football pitches – Rolex plans to produce luxury watches from 2029 to meet the growing demand for its products. The new factory is expected to create 2,000 jobs and thus make a significant contribution to the regional economy.

    Land sale approved
    The General Council of Bulle has approved the sale of the construction site to the Rolex Group by a large majority. Rolex is investing a total of one billion francs in the project and paid 31.4 million francs for the 100,000 square metre site. The planning application has now been submitted and the first visualisations of the planned buildings have been published.

    Innovative construction concept and sustainability
    The new plant will consist of four production buildings connected by a central building. In addition to the administration, this central area will also house catering facilities as well as meeting and rest areas. A striking head-end building at the southern end of the site will house the main entrance.

    Rolex attaches particular importance to environmental friendliness and sustainable design. The factory is to achieve the highest standard of the British Breeam label – a first for an industrial building in Switzerland. The buildings will be arranged so that they are integrated into a park that serves as protection from emissions from the nearby motorway.

    Fifth Rolex production site
    With the new site in Bulle, Rolex is expanding its already highly integrated production chain. The luxury watch manufacturer already operates production sites in Geneva, Chêne-Bourg, Plan-les-Ouates and Biel. Most of the watch components, from movements and cases to dials and bracelets, are produced in-house at these sites.

    Temporary solution in Romont
    In order to expand production capacity before 2029, Rolex will temporarily set up a factory in Romont. Around 250 to 300 employees are to be employed there from the beginning of 2025, most of whom will be newly recruited and trained. These employees will move there once the factory in Bulle is completed.

    With the new factory in Bulle, Rolex is strengthening its position as one of the world’s leading luxury watch manufacturers and investing in the future of the Swiss production site.

  • Zug Estates places third green bond

    Zug Estates places third green bond

    Zug Estates Holding AG has taken another significant step in its sustainable finance strategy. Following the successful launch of green bonds in 2019 and the complete conversion of the bond portfolio to green bonds in 2022, the company has now placed another green bond for CHF 100 million. The issue, which will be paid out on 30 September 2024, has a coupon of 1.65% and a term of seven years. This increases the proportion of unsecured bonds in relation to all interest-bearing financing to around 45%.

    More flexibility for sustainable investments
    In the run-up to the issue, Zug Estates expanded its existing Green Bond Framework into a Green Finance Framework. This innovation enables the company to access other green financial instruments in addition to green bonds. Zug Estates is thus expanding its flexibility in financing sustainable projects and sending a strong signal in favour of the future of green investment.

    Under the new, strict selection criteria, buildings and sites are classified as green if they either emit less than 1 kg of CO2 equivalents per square metre of energy reference area or have prestigious sustainability certificates such as BREEAM, DGNB/SGNI, SNBS or Minergie. Despite these demanding requirements, 95% of Zug Estates’ entire portfolio can be categorised as green properties – proof of the company’s consistent strategy in the area of ecological sustainability.

    The Suurstoffi showcase for sustainable real estate
    A large proportion of Zug Estates’ green properties are located on the Suurstoffi site. This ultra-modern, almost CO2-free development site has also been allocated to the existing and newly launched green bond. As at 30 June 2024, the market value of the Suurstoffi properties earmarked for the green bonds is CHF 418.4 million. This site is an outstanding example of the implementation of Zug Estates’ sustainable development strategies and sets new standards in the field of sustainable construction and operation of real estate.

    Confirmation from international rating agencies
    Zug Estates has received high recognition for its green finance framework from ISS Corporate Solutions, one of the world’s leading ESG research and rating agencies. This Second Party Opinion (SPO) strengthens investor confidence in the company’s sustainability strategy. In addition, Zug Estates was awarded a “C” rating and “Prime” status by ISS (International Shareholder Services) on 23 August 2024. This underlines the high value Zug Estates places on environmental, social and governance-based sustainability.

    Successful placement of the green bond
    The placement of Zug Estates’ new green bond met with great interest from institutional investors. They particularly appreciate the fact that the funds are invested directly in properties that meet the highest sustainability requirements and are already operated almost entirely CO2-free. UBS AG and Basler Kantonalbank acted as joint lead managers for the issue. Admission to trading on the SIX Swiss Exchange has been applied for, which further increases the attractiveness of the green bond.

    Sustainability as a strategy for the future
    With the placement of its third green bond and the expansion of its green finance framework, Zug Estates is once again demonstrating its leading role in the field of sustainable property financing. The company shows how a consistent ecological focus can not only increase the value of the portfolio, but also make an important contribution to reducing CO2 emissions and promoting sustainable development. Zug Estates is thus setting a new standard for the entire property sector.

  • Green light for alpine solar plant

    Green light for alpine solar plant

    The Graubünden-based energy supplier Repower, the municipality of Klosters and Klosters-Madrisa Bergbahnen AG want to jointly construct an alpine solar power plant at the mountain railway. Voters in the municipality of Klosters approved the project on 22 October 2023.

    According to a press release, the Graubünden government has now also approved the construction of the system by Madrisa Solar AG. The site is already well developed thanks to the existing tourist infrastructure and is connected to the power grid.

    The plant in the Züg area is to comprise 25,000 solar modules at an altitude of around 2,000 metres and an area of 156,821 square metres, with a total output of 10.8 megawatt peak. Electricity production is expected to exceed 15,000 megawatt hours.

    The mountain railways already operate five solar installations with an annual output of 294 megawatt hours. These cover up to 20 per cent of their own electricity requirements.

  • The versatile world of wood

    The versatile world of wood

    Utilisation of the wood
    After a certain time, the tree reaches its growth limit. This is the perfect time to fell the tree – it is ready for harvesting. Depending on the tree species, the time until it is ready for harvesting varies between 60 and 150 years. Until then, the tree has had enough time to reproduce through seeds in the gaps in the forest. The plants in the young forest that are best adapted to the local climatic conditions prevail. In this way, the forest remains healthy thanks to natural selection. During thinning, desirable and well-grown trees are left standing as future trees. The abundance of light in the gaps created by felled trees allows a variety of shrubs and annual plants to colonise the ground – increasing biodiversity in a forest managed in this way.

    The majestic forest of Switzerland
    Around a third of Switzerland’s total land area is covered by protected forest. This forest provides protection against natural disasters, is a habitat for animals and plants, a place for recreation and leisure and a source of wood. Sustainability is a fundamental principle that requires the forest to fulfil all these functions in the long term without harvesting more wood than grows back. Enough wood grows in the Swiss forest every ten minutes to build a detached house. Around 60% of Swiss forests consist of conifers and 40% of deciduous trees. A large proportion of the wood felled is processed into sawn timber and planed products, while 10% is used for the production of paper and wood-based panels. A quarter is used directly as firewood. Around 10 million cubic metres of wood grow in Switzerland every year, only half of which is used. Wood is a durable material that regrows itself and plays an important role in the ecological balance. It is therefore sensible and advisable to use our own wood.

    Characteristics of wood
    Wood is a light yet strong material that can bear fourteen times more weight in relation to its weight than steel. Due to its natural cell structure, the static properties of wood are directional. Wood is most resistant along the grain, as it can withstand a hundred times higher tensile forces and four times higher compressive forces in this direction than across the grain. Understanding these static properties is of crucial importance when building with wood. In addition, the warm and pleasant feel of wood gives rooms a special atmosphere. The wood fibres in the installed wood constantly react to the air humidity and thus contribute to a balanced room climate.

    Variety of wood species – differences in the forest and in the home
    Not all woods are identical. The characteristics and appearance of wood vary depending on the tree species – there is a wide range from light to heavy, soft to hard and light to dark. Each type of wood therefore has specific properties that are suitable for different purposes. For example, the heartwood of sweet chestnut or oak, which is preserved with natural tanning agents, is particularly suitable for outdoor use, while long-fibre ash is used for parts subject to heavy wear. Fine-fibre woods such as beech or maple are used in furniture production. Promoting different tree species by using different types of wood helps to increase biodiversity. Each tree grows individually, so its wood may have more or fewer knots, wider or narrower annual rings, be slightly lighter or darker in colour and grow crooked or straight. Each tree trunk and section is utilised according to its qualities. Selected logs of high quality are processed in sawmills into a variety of sawn products such as beams, boards, laths, posts and glulam. Timber that is crooked and knotty or small diameter logs are converted into chipboard and fibreboard in panel mills. The best qualities are processed into veneer. From both an ecological and an economic point of view, it is crucial to determine the appropriate quality for the respective area of application in advance with the supplier.

    Wood-based materials
    The large formats of wood-based materials have made an important contribution to the development of modern timber construction. The production of wood-based materials follows a simple principle: the wood is chopped into boards, chips or fibres and then shaped into a new form with the help of glue. This results in products with standardised properties in a fixed thickness and size. Wood-based materials therefore offer added value and open up a wide range of design possibilities with wood. As a cost-effective building material for everyday use, wood-based materials are indispensable and are available in a wide range from timber merchants and DIY stores.

  • Successful expansion of the “co-operate” research campus in Dübendorf

    Successful expansion of the “co-operate” research campus in Dübendorf

    The expansion of the research campus in Dübendorf, which took place from 2021 to 2024, includes a state-of-the-art laboratory building, a multifunctional building and a new multi-storey car park. These infrastructure measures are crucial in order to meet the increasing demands of research. The additional 30 laboratories and offices offer researchers an improved working environment that meets the latest technological and environmentally friendly standards.

    Sustainability and innovation go hand in hand
    A special feature of the new campus is its focus on sustainable energy generation and utilisation. A newly developed high-temperature geothermal probe system stores waste heat in summer and uses it to heat the buildings in winter. These and other technological innovations, which come directly from the Empa and Eawag laboratories, will not only be used on the campus, but will also be further researched to optimise their efficiency and environmental compatibility.

    A green and car-free campus
    In order to make the campus site more environmentally friendly and pedestrian-friendly, existing parking spaces were moved to the new multi-storey car park and the site was extensively landscaped. A “green belt” connects the two research institutes and creates an inviting atmosphere for employees and visitors. The new campus square at NEST also offers an attractive open space for socialising and recreation.

    Looking to the future
    With the completion of the “co-operate” project, Empa and Eawag have not only modernised their research infrastructure, but also laid the foundations for future innovations. The combination of state-of-the-art construction, sustainable energy utilisation and an improved working environment promotes cutting-edge research and strengthens Switzerland’s position as a leading location for scientific innovation.

  • Urban forests are the backbone of biocities

    Urban forests are the backbone of biocities

    Jerylee Wilkes-Allemann, Senior Scientist in the Department of Forest Sciences at the School of Agricultural, Forest and Food Sciences at Bern University of Applied Sciences(BFH), argues that more attention should be paid to urban forests in urban planning. “These urban forests form the link between rural regions and urban areas,” the researcher is quoted as saying in a BFH article.

    Their diverse services for the ecosystem make them the “backbone of biocities”, the cities of the future. In these cities, green spaces act as central elements of holistic design. Trees and groups of trees, avenues, parks and urban forests provide cooling and thus counteract urban heat islands. They provide oxygen and at the same time filter pollutants from the air. They also provide recreational areas. This is why it is particularly important to protect and maintain forests close to cities, which make up around 18 percent of Switzerland’s forest cover.

    According to the expert, integrating trees into urban planning requires political will. But “unfortunately, the benefits and value of urban forests are still not recognized by many cities”. Trees and groups of trees are often “perceived as a burden, appear to be in the way and are removed”.

    In view of the great demand for living space, they also have a difficult time. However, she is convinced that urban forests are also possible in new construction projects: “In new buildings, existing trees should be integrated into the planning from the outset. This makes far more sense than first cutting down trees and then planting them again.”

  • Photovoltaic output increased tenfold in the last seven years

    Photovoltaic output increased tenfold in the last seven years

    Thurplus takes positive stock of PV expansion over the past seven years. Between 2016 and 2023, Frauenfeld’s municipal energy supplier was able to increase its output more than tenfold from 144 to around 1500 kilowatt peak. In 2023 alone, over 700 kilowatt peak were added, according to a press release.

    In total, these solar systems produce around 1.5 million kilowatt hours of electricity per year. This corresponds to the average consumption of around 330 households. Between 2016 and 2023, the number of shareholders in the PV citizen participation models also increased from 50 to 240, according to the press release.

    “By actively shaping and successfully implementing many sustainable PV projects, Thurplus has managed to achieve this”, says Fabrizio Hugentobler, City Councillor and Head of the Thurplus, Leisure and Sport Department. “Thurplus is well positioned with its solar power, SolarInvest, PV contracting and other solutions.”

    According to the municipal PV strategy for Thurplus, an additional 5 per cent of the total electricity consumption of around 150 gigawatt hours is to be added annually by 2027. This corresponds to a total installed PV capacity of 8 megawatt peak or an electricity production of around 7.5 gigawatt hours per year. Thurplus is looking for suitable roofs from companies and institutions. “Together, we want to make progress and do our bit to ensure that the PV expansion targets are achieved,” says Thurplus Managing Director Peter Wieland.

  • New offices and meeting rooms completed in Bern

    New offices and meeting rooms completed in Bern

    The remodelling and renovation of the offices and meeting rooms at the Halter construction company’s Bern site have been completed. They were realised by Integral design-build AG, part of the Halter Group in Schlieren, within six months. The keys were handed over last week, according to Integral’s LinkedIn page. “By using recyclable materials such as wood, glass and metal, we have created a space that not only minimises our ecological footprint, but also reflects our values of sustainability and aesthetics,” it continues.

    The Halter site in Bern is growing and with it the “need for a larger and more inspiring working environment”, according to a Halter press release. Since the beginning of March this year, an additional 600 square metres of the former Denner site have been rented at the location in the House of Religions realised by Halter. The conversion phase, including dismantling, began in November 2023 and was successfully completed in July 2024. The expansion has increased capacity from 40 to 58 workstations. There are now also additional touchdown workstations and meeting rooms with modern equipment. The move has been successfully completed and the premises have already been filled with life.

    A particular highlight of the remodelling is the impressive staircase, which connects the two floors and creates an open and dynamic working atmosphere, according to the Halter press release.

    The Halter Group comprises a total of ten companies. The head office is in Schlieren, with further locations in Münchenstein BL, Bern, Kriens LU, Lausanne, St. Gallen and Geneva.

  • Further development of the district heating pipeline between Constance and Kreuzlingen

    Further development of the district heating pipeline between Constance and Kreuzlingen

    In summer 2022, Energie Kreuzlingen, KVA Thurgau and Stadtwerke Kon stanz announced their plans to build a cross-border district heating pipeline. The project is now entering the next phase, Stadtwerke Konstanz announced in a press release. The three partners have agreed to define the key points of the project and to draw up a preliminary project. The realisation decision will then be made on this basis.

    The planned district heating pipeline will run from the future waste incineration plant in Weinfelden to Kreuzlingen and on to Constance. In a memorandum of understanding, the partners have defined the roles and distribution of tasks in the planning process. KVA Thurgau will then take over the financing and realisation of the work required for the project planning. Energie Kreuzlingen and Stadtwerke Konstanz will contribute the technical and planning fundamentals.

    KVA Thurgau is to update the feasibility study already carried out on the basis of the specified technical and operational parameters and initiate the planning of the route. At the same time, the partners want to hold talks with potential partners for financing the project. In a second stage, the basis for obtaining a realisation credit is to be developed. According to current planning, the replacement waste incineration plant could supply its first heat by the end of 2031. The district heating pipeline should also be in place by this time if possible.

    Punkt Rufer is developing a program for the Civil Engineering Department of the City of Bern(TAB). According to a press release from the Bern-based consultancy firm for corporate and sustainability development, the two-year project consists of five modules aimed at strengthening the circular economy in future construction projects and existing infrastructure. According to a post on LinkedIn by Philipp Rufer, Owner & Managing Partner of Punkt Rufer AG, the collaboration focuses on knowledge transfer, a lean innovation process and pilot projects derived from this.

    As part of the sustainable development of the city of Bern, the city administration wants to act as a role model and pursue the goals of Agenda 2030 in all areas. This includes a resource-conserving local and regional economy that functions in a circular economy. Punkt Rufer accompanies the project from the initiation, through the conception, development and implementation of a selected circular economy strategy. After implementation, the TAB employees receive final support with the aim of creating a motivated attitude towards the circular economy.

  • Sustainability and quality of life in harmony

    Sustainability and quality of life in harmony

    In a new study published in the “Journal of Cleaner Production”, Empa researchers show that a good life is possible for more than ten billion people within planetary boundaries. Using a technical approach and the so-called donut model, they have calculated that humanity can live sustainably without sacrificing an adequate standard of living. Hauke Schlesier and Harald Desing from Empa’s “Technology and Society” laboratory and Malte Schäfer from the Technical University of Braunschweig have demonstrated this potential.

    The donut as a model for sustainability
    The donut model, consisting of two concentric circles, serves as the basis for the study. The outer circle represents planetary boundaries such as biodiversity, climate and land use. The inner circle symbolises basic human needs. The space between the circles, the donut, represents the sustainable use of natural resources in order to achieve an adequate standard of living. This theoretical basis has now been empirically confirmed.

    Using resources efficiently
    The study shows that an ecological life is possible for more than ten billion people, but far-reaching changes are necessary. There is an urgent need for action, particularly in the energy system and in agriculture. The complete abandonment of fossil fuels and a switch to a plant-based diet are crucial. The sustainable use of phosphorus and nitrogen and the avoidance of land use changes are further key measures.

    A balanced standard of living
    A key component of the transformation is the equalisation of living standards. While the global South would benefit from a significant increase in living standards, resource consumption in the global North would have to be reduced. This applies in particular to living space and individual mobility without compromising well-being. Public transport and healthcare could be expanded without significantly harming the environment.

    Narrow scope for sustainability
    The researchers emphasise that although the donut of sustainable living exists, it is very narrow. However, technological progress and the shift towards a circular economy offer potential for additional ecological leeway. “Our model is based on the current state of technology. Future innovations could expand the donut,” explains Schlesier.

    Empa’s study provides powerful proof that sustainability and quality of life are compatible. It shows the way to an ecologically and socially just life for all people on our planet.

  • New home for senior citizens Greencity 2026

    New home for senior citizens Greencity 2026

    A visionary residential project is being built in the south of Zurich that offers older people a lively and safe environment. The development on construction site B6 in Greencity combines private and municipal involvement. Losinger Marazzi AG is developing the project for the investment foundations of Pensimo Management AG, which are providing a total of 179 flats for older people. Of these, the City of Zurich Retirement Homes Foundation (SAW) will take over 60 flats, while the remaining 119 flats will be let by Pensimo to tenants aged 55 and over. This collaboration represents a new partnership and gives all tenants access to SAW’s services.

    A green centrepiece for Greencity
    Construction site B6 is the latest chapter in the sustainable development of the Greencity district. Since 2014, Losinger Marazzi has been transforming the site of the former Sihl paper factory into Switzerland’s first 2000-watt site. The inner courtyard of the new building will feature green areas, trees and seating, inviting people to linger. Arcades on the ground floor create sheltered access areas to commercial spaces, which could offer facilities such as a medical centre, a fitness studio, a bakery or a café on 3,500 square metres, says René Büchi, the portfolio manager responsible at Pensimo.

    Comprehensive services from SAW
    The City of Zurich Retirement Homes Foundation provides all tenants with a comprehensive service package. This includes a 24-hour emergency call service, extended caretaking, laundry service, social services and various events on the estate. If required, tenants can also take advantage of home help and outpatient care services. Andrea Martin-Fischer, Director of SAW, emphasises: “Our aim is to enable tenants to live independently and safely well into old age.”

    Focus on sustainability
    Greencity’s sustainability goals are consistently applied to the new retirement housing project. Herbert Heinen, Project Manager at Losinger Marazzi, explains: “An optimised load-bearing structure, lightweight walls, a wooden façade and an energy concept with 100 percent renewable energy significantly reduce CO2 emissions and bring the building close to the net-zero target in operation.” Pensimo and Losinger Marazzi are also aiming for certification with the SNBS Gold label. Construction started in March 2024 and the building, designed by JSWD Architekten from Cologne, is scheduled for completion at the end of 2026.

    With this pioneering project, Greencity is setting new standards for sustainable, age-appropriate living and demonstrating how private and public partnerships can create forward-looking solutions.

  • Baden Cantonal Hospital focusses on local companies and sustainability

    Baden Cantonal Hospital focusses on local companies and sustainability

    Baden Cantonal Hospital (KSB) has carried out around 250 publicly tendered procurements over the course of the six-year construction phase of the new building. According to a press release, these tenders resulted in a total of 1066 contracts for work and services. The most recent tender was for the furniture. According to the KSB, the new hospital building lives up to the Swiss made label. 97 per cent of the 177 companies involved in the new building come from Switzerland. Only 3 per cent of the contracts were awarded to companies in Germany and Italy.

    A total of 25 per cent of the companies involved in the construction are based in the canton of Aargau and 40 per cent in the canton of Zurich. “We are proud that KSB has thus made a significant contribution to local and regional value creation,” KSB CEO Adrian Schmitter is quoted as saying.

    Thanks to the high presence of local companies, KSB has also set an example in terms of sustainability, Schmitter continues. “During the construction phase, it was above all a project of short distances for the trade companies involved. This resulted in various synergy effects,” says the CEO. This also applies to the time after commissioning, when reworking, maintenance or similar may be required.

    With a usable area of 76,215 square metres, the new building will offer around 30 percent more space than the building in which KSB has been housed since 1978. Commissioning is scheduled for the end of February 2025.

    The move should then be completed within five days. A total of 4571 cubic metres of medical technology and other goods will be moved, according to a KSB press release. This corresponds to the load of 76 lorries of 40 tonnes each.

  • Sika sets ambitious emission reduction targets

    Sika sets ambitious emission reduction targets

    The Science Based Targets Initiative has validated Sika ‘s short and long-term emission reduction targets, the globally active speciality chemicals group for the construction and automotive industries from Baar announced in a press release. Sika aims to reduce emissions in Scopes 1, 2 and 3 by 30.4 per cent by 2032. By 2050, direct and indirect emissions should have fallen by 90 per cent.

  • Sustainable construction with reusable carbon concrete panels

    Sustainable construction with reusable carbon concrete panels

    The introduction of carbon fibre-reinforced concrete slabs by the ZHAW marks a significant advance in building construction. These panels, which are prefabricated and cut to size in the factory, can be quickly assembled on site. “Our carbon concrete construction system works in a similar way to Lego, but like a modern version of it, with customised components,” explains ZHAW researcher Josef Kurath. This system not only significantly shortens construction times, but also enables flexible adaptations and extensions to buildings.

    Sustainability and reuse
    A prime example of the application of this technology is the 120 square metre pavilion in Winterthur, which serves as an innovation laboratory for sustainable construction. Thanks to a new sharing model, around 90 per cent of the material used can be reused, which represents significant progress compared to conventional methods, where only around 10 per cent can be reused. In view of the fact that cement is responsible for eight per cent of global greenhouse gas emissions, this development represents an important contribution to reducing the ecological footprint.

    Carbon fibres at the heart of
    The CPC (Carbon Prestressed Concrete) concrete slabs are characterised by their durability and environmental friendliness. “Thanks to the new lightweight construction method in concrete, we reduce the CO2 footprint by a factor of two to four and save up to 75 per cent material compared to conventional construction methods,” explains Kurath. The combination of pre-stressed carbon fibres and concrete offers outstanding structural properties: carbon absorbs tensile forces, while concrete absorbs compressive and shear forces. As a result, no cracks occur under load and the panels retain their shape and load-bearing capacity despite their reduced thickness.

    Industrial production and future prospects
    The CPC slabs are manufactured by Holcim in the first plant in Germany, while the carbon fibres are produced in Switzerland, in future using bio-based carbon. “The developed panels will also be produced in this country in the future and the new construction system will be widely used in building construction – the Swiss market in particular is predestined for this,” says Kurath. Further research will focus on optimising the panels for sound insulation and fire protection as well as on earthquake-proof constructions. Innovative joining techniques enable almost endless horizontal planes without additional connecting elements, which further increases the flexibility and efficiency of construction.

  • Load-bearing capacity and usability of timber buildings

    Load-bearing capacity and usability of timber buildings

    Wooden buildings have already proven their load-bearing capacity in the past: The palace of Knossos on Crete, built around 1700 BC, was constructed with wooden pillars and cedar timbers built horizontally into the walls. It survived a severe earthquake around 1400 BC virtually undamaged. The columns and beams of Greek temples and the framework of the mud-brick walls were made of wood until 600 BC.

    Compliance with the SIA structural standards
    Modern timber constructions guarantee structural safety and serviceability by complying with the SIA structural standards. Specialist planners and timber construction companies vouch for this. Unusual events such as fire and earthquakes are also investigated through analyses in various design situations. The variety of construction timber, wood-based materials and fasteners in combination with modern planning and production tools enables the designer to design an optimised load-bearing structure for every new construction project.

    Research and predictability
    The flammability of wood is widespread, but its behaviour in the event of fire is well researched and predictable. The similar strength properties at high temperatures as well as the low thermal conductivity due to the insulating carbon layer and the escaping water vapour make this building material stand out. The efficient fire safety of timber constructions is confirmed by extensive fire tests. With appropriate dimensioning or in combination with other materials, fire resistances of up to 240 minutes can be easily achieved. In contrast to steel and reinforced concrete constructions, timber constructions remain stable even at extremely high temperatures.

    Fire protection standards for timber components in Switzerland
    Fire-resistant timber components that are protected with non-combustible panels are considered non-combustible according to Swiss fire protection regulations. This shows the recognition of the fire protection authorities for the results of extensive studies, which prove that the combustibility of a building material is not the decisive criterion, but rather that the correct fire protection design of a construction has a greater influence on the fire behaviour. Current regulations permit the use of wood in various construction applications without restrictions and even in high-rise buildings under certain conditions. Timber therefore has a wide range of applications in all building categories and uses.

    Safe timber surfaces in interior spaces
    The requirements for structures in safety-sensitive areas such as vertical escape routes are met by suitable timber components with non-combustible fire protection cladding. Visible wooden surfaces are permitted in interior rooms, with the exception of escape routes.

    Compliance with quality requirements
    Thanks to the “Fire safety and wood” research and development project, which has been running since 2001, comprehensive technical and methodological principles and safe designs for timber components have been developed. An industry-specific quality assurance system defines the fire safety-related quality standards for wood in construction. In Switzerland, high-quality timber buildings are erected in strict compliance with quality requirements. The Lignum documentation on fire protection serves as a guideline and shows the many different ways in which wood can be used to ensure the correct realisation of timber components in small, large or tall buildings. It corresponds to the current state of the art in fire protection in accordance with Swiss regulations.

  • Hybrid construction methods using wood, concrete and steel

    Hybrid construction methods using wood, concrete and steel

    Integration and connection technologies
    A significant challenge in hybrid constructions lies in the integration of different materials. When joining wood and concrete, special fasteners must be used to take into account the different properties of the materials, such as the moisture sensitivity of wood.

    Developing an understanding of mixed-structure components
    Hybrid components combine two or more materials that are carefully selected for their specific properties. An example of this is the combination of concrete, which can absorb compressive forces, and steel, which is responsible for tensile forces. This combination results in innovative constructions that could not be realised with the individual materials alone.

    Applications in the field of prefabricated components
    In the field of prefabricated construction, hybrid construction methods are used in particular for the production of large and heavy components. Here, the components are first manufactured separately and later joined together to form a complete unit. This approach enables a more flexible design and simplifies transport and assembly.

    Revolutionary combinations for ceilings
    Innovative ceiling constructions with a sandwich cross-section use hybrid technologies to produce robust yet lightweight components. This advanced technology allows the integration of installation systems and contributes to the energy efficiency of the building.

    Combining wood and concrete
    The combination of wood and concrete in ceiling structures offers the opportunity to combine the strengths of both materials and compensate for their weaknesses. Wood can take on the load-bearing role, while concrete is used for sound insulation and the integration of heating or cooling systems.

    Innovative advances in the future
    The further development of hybrid construction methods strives to enable more efficient, more cost-effective and more environmentally friendly construction techniques. This includes improved manufacturing processes, increasing load-bearing capacity and speeding up the construction process. Overall, hybrid construction represents a forward-thinking approach to construction that combines the benefits of different materials to create efficient, sustainable and aesthetically pleasing structures.
