  • ZEV energy communities as the key to the future

    ZEV energy communities as the key to the future

    The ZEV is an innovative solution for energy supply in properties. This form of cooperation allows owners and tenants to benefit from renewable energy that is generated and consumed jointly. ZEV makes it possible to cover energy requirements more efficiently, not only reduces operating costs, but also makes an important contribution to reducing CO₂ emissions. In the SVIT Zurich seminar series, the basics of ZEV are presented in detail and their relevance for property management is comprehensively examined.

    A legal framework for ZEV
    In order to successfully implement ZEV, it is essential to understand the legal framework. The seminar provides an overview of relevant regulations and legal aspects so that the legal requirements are known. This knowledge is crucial in order to avoid potential legal pitfalls and ensure legally compliant implementation.

    Focus on successful implementation
    Practical examples are used to illustrate individual building solutions and comprehensive site solutions. By analysing specific projects, participants will learn how these concepts not only work in theory, but are also successfully applied in reality. The exchange of best practices will encourage participants to develop innovative ideas for their own realisations.

    Efficient structures
    Another focus of the seminar is on organising the operation of ZEV in rental and condominium properties. Efficient management and transparent billing are crucial to the success of these projects. Experts will explain how an optimal operational organisation can be designed to maximise the benefits of the ZEV for all parties involved and guarantee smooth implementation.

    Future prospects
    Finally, we will take a look into the future. How will ZEV continue to develop in the property sector? What trends are emerging and what opportunities are there for professionals? The SVIT seminar not only offers valuable impulses for current practice, but also visionary perspectives for the property management of tomorrow. Let us drive forward the energy transition and establish ZEV as the key to a more sustainable property industry.

  • Researchers develop commercially viable salt batteries for safe energy storage

    Researchers develop commercially viable salt batteries for safe energy storage

    Researchers from the Dübendorf-based Materials for Energy Conversion Laboratory of the Swiss Federal Laboratories for Materials Science and Technology(Empa) are continuing an Innosuisse project started by Ticino-based salt battery manufacturer Horien Salt Battery Solutions. The aim of the research collaboration is to develop economically attractive and usable salt batteries, according to a press release. Salt batteries are batteries in which the electrolyte is a solid, namely a ceramic ion conductor based on sodium aluminium oxide. The cathode is based on a granulate of common salt and nickel powder. The sodium metal anode is only formed during charging. Unlike conventional lithium-ion batteries, salt batteries are not flammable. They can therefore be used in areas where lithium-ion batteries are not permitted, such as in mining and tunnelling or on oil and gas platforms. Further advantages are their longevity and the significantly cheaper procurement of the raw materials. In contrast to the lithium-ion competition, the raw materials are cheap and available in large quantities, according to the press release.

    One disadvantage of these batteries is their high operating temperature. To be ready for use, a salt battery requires a temperature of 300 degrees Celsius. The researchers are looking for options to make the applications more economical. “Depending on the application, it is more economical to keep a battery warm than to cool it,” Empa researcher Meike Heinz is quoted as saying in the press release.

    Another endeavour is to operate the solid-state batteries nickel-free. The aim is to replace the cathode material nickel with other metals such as zinc. The aim is to establish salt batteries as long-term stationary storage systems thanks to their safety, long service life and the absence of critical raw materials.

  • Canton of Lucerne votes on expansion of renewables

    Canton of Lucerne votes on expansion of renewables

    On 24 November, voters will decide on a bill to amend the Planning and Building Act (PBG). The canton of Lucerne explains in a press release that the amendment to the PBG is intended to accelerate the expansion of renewable energies. Various measures from the planning report on climate and energy policy, which was approved by parliament in 2022, would require these amendments to the PBG. For example, in future, charging stations for electric cars should be planned directly when building car parks. The SVP parliamentary group rejected these changes as they believe that the production of renewable electricity should be voluntary and “not enforced by regulations”. The Centre, FDP, SP, Green and GLP parliamentary groups, on the other hand, approved the government council’s proposal. The cantonal council also voted in favour of the amendments to the PBG by 83 votes to 27. The referendum on 24 November will now take place because a committee has launched a referendum.

    The cantonal government recommends that voters approve the amendments. “We are still investing too much money in importing fossil fuels from abroad. By investing in our domestic renewable energies, we are freeing ourselves from our dependence on foreign countries and generating even more added value here at home,” Fabian Peter, the cantonal councillor responsible for the legislative amendment, is quoted as saying in the press release.

  • Green aluminum shutters

    Green aluminum shutters

    The Aadorf-based sun protection manufacturer Griesser will produce window shutters made from so-called green aluminum at its Austrian site in Nenzing in the future. According to a press release, the material used will consist of 65 percent process and consumer scrap and 35 percent primary aluminum. The latter will be manufactured using renewable energy from producers in Europe. By using green aluminum in the production of folding shutters, Griesser aims to significantly reduce its CO2 footprint.

    “Folding shutters account for very large production volumes within the window shutter range,” Urs Neuhauser, CEO of the Griesser Group, is quoted as saying in the press release. “With 53 percent of the sashes, Model A is the top model. We want to prioritize clearly according to impact, which is why we have decided to start with these products.”

    By switching to green aluminium, 160 tons of the material will be used in the production of window shutters in Nenzing every year. At the same time, Griesser will reduce its CO2 emissions by 300 tons. This corresponds to 35 percent of emissions in the shutters product area. The company assures that the use of the new material has no disadvantages in terms of stability and quality. The six-year guarantee remains in place, according to the press release. According to Neuhauser, the entire range of window shutters is to be converted to production with green aluminum by the end of 2025.

  • Boost My Startup Challenge 2024

    Boost My Startup Challenge 2024

    The Bern-based ClimateTech company Neustark has won this year’s Boost My Startup Challenge. According to a press release, Neustark came out on top against five other competitors in the competition organized by the consultancy firm WSP from Lucerne and the major Zurich bank UBS. The Bern-based company, a spin-off of the Swiss Federal Institute of Technology in Zurich(ETH), was recognized by the judges for its CO2 mineralization technology. According to the company, the process converts carbon dioxide into limestone, which is bound to the pores and surface of concrete granulate. The granulate carbonated in this way can then be used in road construction or for the production of recycled concrete. As Neustark forecasts, the company wants to store a total of 1 million tons of carbon dioxide from the air by 2030.

    The challenge now won gives the Bern-based company access to WSP’s teams, offices and customer network as well as support from UBS Growth Advisory. In addition, the company can benefit from funding, either from UBS Growth Advisory or from WSP.

  • Solar power: first system of the second project in operation

    Solar power: first system of the second project in operation

    Zaugg Schlieren AG put the first third of its second solar plant in Schlieren into operation in mid-October. The corresponding building permit was only applied for at the end of February, the Schlieren-based packaging and logistics specialist reports in a post on LinkedIn. The installed capacity is stated as 98.28 kilowatts peak. This means that around 95 megawatt hours of solar power can be produced each year.

    By 2026, Zaugg Schlieren plans to have installed solar systems with a total output of 271.47 kilowatts peak. This means that around 263 megawatt hours of solar power can be generated each year. The company was founded in 1977 by Werner Zaugg on the site of the recently decommissioned gasworks in Schlieren. Since 2011 , Switzerland’s first professional transport packaging and crate manufacturer has also been represented with a site in China.

  • Lucerne’s Wesemlin neighbourhood is leading the way, mastering the energy transition together!

    Lucerne’s Wesemlin neighbourhood is leading the way, mastering the energy transition together!

    Despite existing technologies and support measures, switching to climate-neutral forms of heating is still a challenge in Switzerland. In particular, high investment costs and uncertainty about the best technology are holding many owners back. This is where the Wesemlin neighbourhood in Lucerne comes in: In a collaborative project with the HSLU, the aim is to develop community-based, customised heating solutions that go beyond individual actions and involve the entire district in the energy transition.

    The QUBE project – a model for change
    The QUBE research project by HSLU and Innosuisse is based on the assumption that community heating solutions achieve more than isolated measures. The transdisciplinary team developed a method to accompany such change processes that takes equal account of technical and social factors. The pilot project found a perfect test environment in the Wesemlin neighbourhood: residents, authorities and teams of experts worked together to establish climate-neutral energy sources. “Only by involving all stakeholders can we find viable and customised solutions for the local energy transition,” emphasises Prof. Alexa Bodammer from HSLU.

    Community expertise as a driving force
    Initially unfamiliar, the open dialogue in the Wesemlin district brought decisive progress. Residents were able to contribute their own ideas, experiences and concerns, while the research team took on the role of technical moderator and incorporated technical analyses. Business partners and authorities supported the planning, offered data and helped to clarify funding opportunities. “Cooperative projects create possible solutions that would never be achieved through individual solutions,” explains Stefan Mennel from the Institute of Building Technology and Energy IGE.

    Energy transition as a joint task
    The QUBE project impressively demonstrates that technical innovations alone cannot bring about the energy transition. Sustainable change can only be achieved if local residents are involved in shaping it and the solutions are socially accepted. Through workshops, information events and network meetings, technical and social expertise was pooled in order to develop an implementable and accepted energy strategy for the Wesemlin neighbourhood. “This collaborative approach acts as a multiplier for change,” says Bodammer.

    Knowledge building and networking as a lever for success
    The collaboration with experts and authorities led to a great increase in knowledge at an individual level. Today, neighbourhood residents are well equipped for discussions with technical providers and energy suppliers. For Daniel Bolliger, resident and researcher at HSLU’s iHomeLab, the project demonstrates the value of collective engagement: “QUBE has opened up access to relevant stakeholders and energy providers – an opportunity that individuals would otherwise not have had.”

    A model for the future
    The concepts for the neighbourhood energy transition developed as part of QUBE can be used in a variety of ways. The methodology for supporting and moderating cooperative processes provides a blueprint for similar projects in other neighbourhoods and cities. According to Stefan Mennel, interdisciplinary collaboration is the key: “Only through cross-disciplinary, cooperative collaboration can we ensure that everyone involved is properly understood.” This applies both within the project team and in dialogue with the residents of the neighbourhood. The QUBE project has shown that a sustainable, community-led energy transition is possible – a model for the future.

  • Strüby Unternehmungen receives first certificate for realised Minergie site

    Strüby Unternehmungen receives first certificate for realised Minergie site

    Energy efficiency, energy self-sufficiency and heat protection are currently major issues and will become even more important in the future. Since 2023, not just a single house, but an entire site can be certified by Minergie, meaning that the surrounding area can also be increasingly included in the planning of residential construction projects. On 2 September 2024, the “Fischermätteli” in Burgdorf BE received the first definitive site certificate from Minergie in Switzerland and thus reached a new level in sustainable construction.

    Label with high requirements
    The new, comprehensive Minergie site standard is supported by the Minergie Association, the cantons, the business community and the Swiss Federal Office of Energy. The Minergie site is characterised by very low energy consumption, minimised greenhouse gas emissions during construction and operation and maximum self-sufficiency with renewable energies. The buildings have above-average heat insulation and controlled air exchange. The design of the outdoor space increases climate resilience and the quality of stay, for example through suitable planting and shading. The Minergie site also incentivises climate-friendly mobility.

    Over 6600m3 of Swiss wood
    The Fischermätteli residential construction project was successfully completed by Strüby Unternehmungen in autumn 2023 after a construction period of around three and a half years. The ten apartment blocks with a total of 168 condominiums were built on a former commercial site in Burgdorf BE. Over 6600m3 of Swiss timber was used in the construction, making “Fischermätteli” the largest project in Switzerland to combine the Minergie-A-ECO standard and Swiss timber.

    Climate-friendly environmental design
    One hundred per cent of the energy for the entire site comes from renewable sources: the electricity from the photovoltaic systems on the building roofs, the heat for heating and hot water from a heating centre supplied with Swiss pellets. The finely meshed mobility concept focuses on electromobility, car sharing, bicycles and public transport. A co-working space promotes working from home and thus indirectly relieves traffic congestion. In addition, the climate-friendly environmental design based on the sponge city principle ensures natural and efficient cooling in summer and makes the “Fischermätteli” a hotspot of biodiversity thanks to the countless native plants.

    Success thanks to a climate-friendly overall concept
    Pius Kneubühler, Managing Director Real Estate Development & Construction at Strüby Unternehmungen, can confirm that the climate-friendly overall concept in line with the Minergie site standard pays off not only for the residents, but also for the investor. “The success has already manifested itself in the marketing of the condominiums. Demand was so pleasing that all flats were sold by the time construction was completed.”

  • CO₂ reporting obligation in the construction industry

    CO₂ reporting obligation in the construction industry

    According to the new requirements in the Swiss Code of Obligations, certain companies are obliged to systematically measure and disclose their CO₂ emissions. Companies that cause high emissions or are involved in complex supply chains – including construction companies, craftsmen and manufacturers of building materials – are particularly affected. Building owners and major projects are increasingly demanding proof of the corporate carbon footprint (CCF), meaning that companies wishing to participate in tenders will sooner or later be obliged to submit CO₂ reports.

    CO₂ accounting – what is important
    The CO₂ accounting of companies in the construction industry is based on three main areas, also known as scopes. Scope 1 comprises direct emissions from own facilities and vehicles, such as those generated by the use of construction vehicles. Scope 2 takes into account indirect emissions from purchased energy, such as electricity consumption. Scope 3 refers to indirect emissions along the entire value chain, i.e. emissions generated during the production and transport of materials such as concrete and steel.

    Scope 3 emissions often account for the largest share in the construction industry in particular. In fact, up to 90% of emissions can be generated indirectly, which is why a comprehensive carbon footprint should also take the entire supply chain into account. It is therefore particularly important for craft businesses and manufacturers to accurately record the Scope 3 area in order to fully map and optimise their emissions balance in the long term.

    Act now
    Even for companies that are not yet directly required to report, it can make sense to draw up a carbon footprint at an early stage. Sustainable practices are increasingly becoming a decision-making criterion in tenders, and proof of reduced emissions may soon be an important competitive factor. A clear CO₂ strategy signals to your business partners and customers that you want to play an active role in shaping the future and are equipped to meet the requirements of the construction industry.

    Save costs through measures
    Construction companies and material manufacturers that are preparing for a CO₂ balance sheet have the opportunity to reduce emissions and operating costs through energy-efficient machines or optimised transport routes. These savings not only protect the environment, but can also create long-term economic benefits.

  • Revolutionary building monitoring

    Revolutionary building monitoring

    Monitoring the statics and stability of structures requires maximum precision. This is precisely where the innovative metamaterial from the Karlsruhe Institute of Technology (KIT) comes in. This metamaterial, with artificially produced structures, exhibits exceptional elongation properties that conventional materials do not offer. Developed by a research team led by Professor Martin Wegener, the material can “communicate” forces and deformations over large distances, which was previously considered unthinkable in structural monitoring.

    Overcoming local limitations
    Metamaterials were previously limited to local interactions. The new material from KIT, however, enables the building blocks to interact with each other over long distances. Dr Yi Chen from KIT compares this property to “direct communication” within the material. A development that could revolutionise materials research and structural monitoring. This new type of structure opens up the possibility of monitoring buildings over a large area and reacting to structural changes at an early stage.

    Unusual elongation properties for greater safety
    One remarkable feature of this metamaterial is its reaction to elongation. It exhibits uneven expansion and compression in different sections. Unlike materials such as rubber, compression even occurs in some areas, which can indicate specific loads. These high sensitivity properties of the material make it ideal for engineering teams to closely monitor critical areas of a structure and react proactively to changes.

    More than construction monitoring
    The high sensitivity of the metamaterial opens up new possibilities not only in the construction industry, but also in biotechnology. The ability to precisely measure forces over large areas could also be used to characterise cell forces or for biological applications. The development therefore not only advances structural monitoring, but also offers new approaches in biological research.

  • Solar park project completed five months earlier than planned

    Solar park project completed five months earlier than planned

    Nexans Switzerland has commissioned its new solar park at the Cortaillod site five months ahead of schedule. It consists of ten individual systems, each of which was installed on a different roof. These independent units were then connected together to form a higher-level system. According to a statement from the cable manufacturer, this required adaptations to the specific architectural and structural features.

    This approach made it possible to completely avoid interfering with production activities at the site during the installation work. “The result: a 100 per cent successful commissioning, almost five months earlier than planned.”

    Since the summer of 2023, a team of Groupe E Greenwatt specialists from the Boudry NE site has installed over 4,000 solar modules, each with a capacity of 430 watts, “under demanding technical conditions”. The solar park has a total output of 1.7 megawatts. Together with a 700 kilowatt system previously installed by Groupe E, Nexans now achieves a self-consumption rate estimated at over 90 per cent.

    “This strategic partnership supports our goal of continuing to reduce our environmental footprint and develop our business sustainably, and strengthens our energy resilience,” Nexans Switzerland CEO Marco Spinelli is quoted as saying. “Even without these plants, Nexans only consumes electricity that comes 100 per cent from renewable sources, and has done so since the beginning of the year.”

  • 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.

  • Zurich utilities expand smart meter network

    Zurich utilities expand smart meter network

    According to a press release, the electricity utility of the city of Zurich(ewz), Energie 360° and the Zurich water utility (WWZ) are expanding the use of smart meters. They are replacing analog meters that are still read by hand. This allows consumption data to be recorded and transmitted more quickly. By reading electricity, water and gas digitally, customers would have more transparency about their consumption. For the water supply, there are additional advantages in terms of troubleshooting. Any leaks and pipe damage can be detected more quickly using digital water meters.

    Ewz has been working on the supply of digital meters since August 2024. Gas supplier Energie 360° has been involved in the expansion of smart metering systems since April. Ewz plans to replace as many conventional meters as possible with digital meters by 2029. Around 300,000 smart meters are to be available in the city of Zurich and a further 4,000 in the ewz supply area in Graubünden. WVZ has announced the installation of 33,000 smart water meters by 2036.

    “With the installation of smart meters, we are taking an important next step towards the digitalization of the supply networks,” said City Councillor Michael Baumer, Head of the Department of Industrial Operations.

    Like their predecessors, the smart meters will continue to be installed primarily in basements.

  • Cooperation for intelligent lighting and building solutions

    Cooperation for intelligent lighting and building solutions

    The technology company ABB and the Austrian Zumtobel Group are working together on the further development of intelligent lighting and building solutions as well as direct current applications. According to a press release, the companies will focus on integrating ABB’s building automation solutions with the Zumtobel Group’s lighting management systems.

    Both companies expect the “combined expertise” to result in “more efficient, more sustainable and more user-friendly smart building environments”. To this end, the application of sensor-based lighting solutions will be accelerated with the aim of “optimizing energy efficiency, increasing the comfort of building users and maximizing the effectiveness of heating, ventilation and air conditioning control”. The added value is intended to benefit customers in the commercial, industrial and administrative sectors.

    The cooperation is intended to promote innovations in the use of direct current technology in large-scale industrial applications. The resulting synergies should make buildings more efficient, sustainable and user-friendly. The use of modern industrial power grids would allow renewable energy to be used on a larger scale. This saves resources, reduces feed-in power and leads to stable grids and an open system for users.

    “Our partnership concept enables us to better address innovation, standardization and sustainability and to continue to play a pioneering role in new technologies,” Lucy Han, EVP for Building and Home Automation Solutions at ABB, is quoted as saying.

  • Holcim and Amazon support start-ups for sustainable construction

    Holcim and Amazon support start-ups for sustainable construction

    The Zug-based building materials company Holcim and the Climate Pledge Fund, which belongs to Amazon, have decided to support start-ups that are committed to sustainable construction, according to a press release. The money donated from the fund for the company 14Trees, which operates in Africa, will be used for high-rise buildings using 3D printing technology. 14Trees uses the technology developed by Holcim and British International Investment(BII) for 3D-printed buildings such as schools, residential buildings and a low-carbon data center. The company intends to use the funding provided for Paebbl to further advance its mineralization technology, which can be used to store CO2 in concrete.

    “By investing in 14Trees and Paebbl with Amazon’s Climate Pledge Fund, we can scale up these breakthrough technologies to push the boundaries of sustainable construction – from 3D printing to turning concrete into a carbon sink,” Nollaig Forrest, Chief Sustainability Officer at Holcim, is quoted as saying in the press release.

    Francois Perrot, Managing Director of 14Trees, was delighted to have found Amazon and Holcim as investors. For Marta Sjögren, co-founder and co-CEO of Paebbl, this funding round “enables us to take even bolder steps in our mission to make the built environment a cornerstone of the decarbonized economy”.

  • Sustainable circular economy in the construction industry

    Sustainable circular economy in the construction industry

    One of the key challenges facing the construction industry is the reduction of CO2 emissions. By decarbonising processes and procedures in the gravel, concrete and recycling industry, companies can make an important contribution to sustainability. The autumn event offers an industry roadmap to help companies identify and implement sensible measures to reduce emissions.

    Optimising concrete as a building material for sustainable construction projects
    Concrete is still one of the most widely used building materials in the world. However, sustainability also plays a decisive role here. The autumn event will show how the sustainability properties of concrete can be optimised and used in a targeted manner. At the end of a building project, the question arises as to how materials can be reused. Options such as renovation, refurbishment or recycling offer sustainable solutions, which will be discussed at the event.

    Pollutant control and separation as the basis of the circular economy
    A successful circular economy requires the targeted separation and control of pollutants. This begins with the planning of a construction project and continues with material treatment and disposal. At the autumn event, the key aspects of pollutant separation will be explained, which are essential for achieving sustainable results in dismantling projects.

    Dealing with persistent substances such as PFAS
    Per- and polyfluorinated alkyl compounds (PFAS) are a group of persistent substances that are increasingly becoming the focus of environmental research. These substances are ubiquitous and pose a particular challenge in the circular economy. The autumn event will provide insights into the possibilities and limitations of dealing with PFAS and highlight solutions that can be implemented in practice.

    Innovative decarbonisation projects in practice
    A highlight of the autumn event is the presentation of the world’s largest electric melting furnace for rock wool. This innovative project shows how decarbonisation is implemented in practice and what potential lies in the production of stone wool. Experts will gain practical insights into the technical developments and their contribution to a sustainable circular economy.

  • Zug adopts sustainable energy targets

    Zug adopts sustainable energy targets

    Energy consumption in the canton of Zug amounts to almost 3,000 gigawatt hours per year, with buildings and mobility accounting for the largest share. The cantonal government’s new energy and climate strategy (EKS) aims to reduce energy consumption and rely more heavily on renewable energies. At the same time, the government wants to strengthen security of supply in the canton and reduce greenhouse gas emissions to net zero by 2050. With clear interim targets up to 2030, the government is concretising the path to these ambitious goals.

    Investments in solar power and energy storage
    A central component of the strategy is to increase the production of solar power in the canton. At the same time, investments in innovative energy storage technologies such as hydrogen are planned. “We want to shape the energy infrastructure of the future through close collaboration with industry and science,” explains Construction Director Florian Weber. Buildings in the canton should also increasingly serve as energy producers and thus become an energy hub.

    Sustainability in agriculture and negative emission technologies
    As part of the KERB sustainability project, the canton is focussing on measures in agriculture to reduce CO2 emissions. Forests and moors play a central role in CO2 sequestration. For unavoidable emissions, the canton is focussing on negative emission technologies that are intended to permanently remove CO2 from the atmosphere. A study is to determine the potential of these technologies in the canton.

    Adapting to climate change
    In addition to reducing emissions, the canton of Zug is also preparing for the effects of climate change. A cantonal natural hazard strategy aims to minimise climate-related risks such as heat and invasive pests. At the same time, investments are being made in climate-adapted road surfaces and sustainable forest management to ensure both protection and recreational areas.

  • A new standard in the canton of Zurich

    A new standard in the canton of Zurich

    Protect birds, prevent collisions
    Environmental protection is the focus of this new law, which is intended to protect avian fauna. According to estimates, over three million birds lose their lives in Switzerland every year as a result of collisions with mirrored façades and window panes. In future, new buildings are to play a pioneering role here and take measures to prevent such tragedies. The Cantonal Council today decided at first reading that planning must take bird safety into account in future. Following the successful vote of 147 votes to 30, the bill will now be passed to the drafting committee and is expected to be formally enshrined in law in around four weeks.

    Room for manoeuvre for sustainable solutions
    However, the discussion about the exact wording led to controversial debates. While the SP called for a more comprehensive regulation that would also include existing buildings, parliament agreed on the current compromise. “It is crucial that we implement bird protection now, even if we would have liked more,” emphasised Theres Agosti from the SP. Thomas Forrer from the Greens also expressed the wish that larger conversions should also be included in the new bird protection article.

    Challenges for developers and authorities
    While some parliamentary groups supported the initiative, the FDP expressed reservations and saw no urgent need for action. They argued that the existing legal framework was already sufficient and that plans that endanger birds should not be authorised. Nevertheless, Agosti emphasised that there was often insufficient awareness of the problem of bird protection and referred to examples such as the Winterthur Cantonal Hospital, which caused hazards due to transparent glass railings.

    Green Building Director Martin Neukom also recognised the dangers posed by glass and emphasised that a comprehensive law would be important to ensure a sustainable future. Nevertheless, the cantonal government expressed concerns about the additional workload for building owners and authorities and ultimately rejected the bill.

  • New grid platform facilitates self-consumption of solar power and battery storage

    New grid platform facilitates self-consumption of solar power and battery storage

    According to a press release,Evaarist is launching a grid platform “for the democratisation of energy self-sufficiency”. The Sion-based start-up wants to enable more owners of existing solar installations to consume more of their solar production themselves. In addition to the autarcie.ch platform for controlling solar power from the roof, Evaarist also offers easy-to-install battery packs.

    “Energy self-sufficiency is something that is close to our hearts,” says Loïc Viret. He founded Evaarist 2023 with Julien Morard and Stéphane Curchod. The engineering firm specialises in renewable energies and energy self-sufficiency and launched the autarcie.ch platform as part of the Espace Innothèque at the Foire du Valais 2024, according to the press release.

    Evaarist’s considerations were based on the observation that almost 98 per cent of the 240,000 or so existing solar installations in Switzerland are not equipped with batteries. Evaarist offers universal battery systems for solar roofs. A battery pack is installed in parallel with the electricity grid, the solar modules and the existing inverters. “This will make it possible to store and work with additional energy. And above all, the degree of self-sufficiency can be increased to 65 to 85 per cent, compared to 20 to 30 per cent without batteries,” Viret is quoted as saying.

    Furthermore, Evaarist wants to bring the material directly from the manufacturer to the customer and the installation will largely be carried out as a “do it yourself” project. Thanks to an agreement with a German importer, autarcie.ch offers battery packs from CHF 5800 for 10 kilowatt hours.

  • Switzerland’s first low-pressure turbine commissioned in Martigny-Bourg

    Switzerland’s first low-pressure turbine commissioned in Martigny-Bourg

    The Forces Motrices de Martigny-Bourg (FMMB) have commissioned Switzerland’s first low-pressure turbine. As Alpiq writes in a press release, 850,000 kilowatt hours of electricity can now be generated per year in the underwater channel of the river power plant on the Dranse. The power plant’s current three production units generate 89 million kilowatt hours per year.

    Depending on the flow rate, the low-pressure turbine can turbine between 1.25 and 10.2 cubic metres of water per second. It is designed for a head of up to 2.5 metres. It has no additional impact on the environment and does not affect existing electricity production. “The installation of this new low-pressure turbine makes it possible to make the best possible use of the available water resources while at the same time being considerate of the environment,” said power plant manager Georges-Alain Zuber in the press release.

    Planning for the plant began in 2011. It is being subsidised with funds from the cost-covering feed-in remuneration.

    The power plant was built in 1908 as an electricity generator for Electro-Chimie de Paris. Today, the municipalities of Bovernier with 23.04 per cent, Sembrancher with 18.72 per cent, Martigny with 17.22 per cent, Martigny-Combe with 15.58 per cent and Vollèges with 1.64 per cent as well as Alpiq with 18 per cent and the Valais energy supplier FMV with 5.8 per cent have a stake in FMMB.

  • Sika focuses innovation strategy on sustainability

    Sika focuses innovation strategy on sustainability

    At the Capital Markets Day on October 3 in Zurich,Sika explained the company’s plans for future growth. Sustainability and the circular economy are of great importance. This was already indicated by the motto of the Capital Markets Day. It was “Unlocking growth – longevity and circular economy in construction and industry”.

    According to the globally active specialty chemicals group for construction and industry, increased requirements in terms of sustainability and the circular economy are changing the entire construction industry. “Climate change and the increasing scarcity of resources are megatrends that require sustainable, long-lasting solutions in construction,” Thomas Hasler, CEO of Sika, was quoted as saying in a press release on Capital Markets Day. Longevity brings ecological and economic benefits for both new buildings and renovation projects. “These positive aspects can be further enhanced by the use of recycled materials,” says Hasler. Sika is therefore “consistently aligning its own innovation strategy with these trends”. In addition, the Group has “a comprehensive portfolio of technologies that combine performance and sustainability”.

  • Smart buildings for the future

    Smart buildings for the future

    The city of Schaffhausen has a comprehensive innovation programme with its Smart City strategy. As part of the “Smart building management” project, it has been working with partners such as VIBOO to find solutions to optimise the management of its buildings. The predictive control technology from VIBOO, an Empa spin-off, offers a future-oriented answer to this challenge. By utilising weather and occupancy data, the heating system can be automatically set to the optimal conditions to both save energy and increase comfort for users.

    The spin-off uses a combination of machine learning and building physics to create thermal building models based on measurement data. These models are integrated into a predictive control system that predicts the thermal behaviour of the building, taking into account the weather forecast and user preferences. In this way, energy use is optimised every few minutes and adapted to the building.

    Saving energy in historic buildings
    A pilot project in the listed Bach school building demonstrates the potential of this technology. The aim is to reduce heating energy consumption by at least 20% while increasing thermal comfort. The school building, which has energy deficits due to its age, is ideally suited to this type of smart building management. Initial results are already available and indicate a significant reduction in energy consumption. If the success is confirmed in the further course of the project, a rollout to other buildings is planned.

    Integration into the energy sector of the future
    Predictive heating systems not only offer advantages in terms of energy savings and comfort, but are also ideally prepared for the future requirements of the energy market. The technology is able to use time-dependent energy prices and can adapt to demand response programmes, which are becoming increasingly important in an increasingly decentralised energy supply with renewable energies.

    The system aims to fully integrate buildings into the energy sector to reduce peak loads and maximise the use of renewable energy. The vision goes far beyond energy efficiency – buildings should actively participate in the energy market in the future and make an important contribution to stabilising the electricity grid through intelligent networking.

    Validated savings in different building types
    The technology has already been successfully tested in residential and commercial buildings, schools and public buildings for heating and cooling. Energy savings of between 20% and 40% have been achieved compared to conventional control systems. These savings are accompanied by improved responsiveness to weather changes, which further increases comfort for building users.

    With this project, the city of Schaffhausen is setting an example for the use of forward-looking technologies to improve energy efficiency. If the positive results in the Bach school building are confirmed, this could pave the way for the widespread use of this forward-looking technology in other buildings in the city. Predictive heating systems offer a promising solution for significantly reducing energy consumption in existing buildings while increasing comfort – a decisive step towards a sustainable future.

  • Progress and outlook for the cantonal climate strategy

    Progress and outlook for the cantonal climate strategy

    Successes include the introduction of a procurement guideline for CO2-free vehicles in the cantonal administration and the creation of a legal basis for financial support for flood protection measures. Two measures that have been finalised, while a further 47 are currently being implemented. New administration vehicles must now have a CO2-free drive system, which represents an important step towards a more climate-friendly administration. In addition, the Water Management Act has created the basis for promoting flood protection projects, which are essential for adapting to climate change.

    Public relations work as the key to raising awareness
    Another key aspect of the climate strategy is raising public awareness. Every year, a “climate walk” is organised on a climate-related topic to present projects to citizens. This year’s focus was on the energy-efficient refurbishment of an apartment block, which was upgraded from efficiency class G to class B. This shows how effective refurbishment measures can help to reduce energy consumption and CO2 emissions.

    Challenges in the area of fossil fuels and renewable energies
    The latest climate figures show that the proportion of oil heating systems in residential and service buildings has fallen by 5 per cent, while the proportion of heat pumps has risen by the same amount over the same period. Nevertheless, the proportion of natural gas heating systems remains unchanged, which contradicts the climate policy goals. In order to achieve the goal of a climate-friendly energy supply, the transition from fossil fuels to renewable energies must be accelerated.
    On a positive note, electricity production from photovoltaic systems in the canton has more than doubled since 2015. This shows that the use of renewable energies is progressing, even if considerable efforts are still required to achieve the climate targets that have been set.

    Potential for improvement in the cantonal administration
    The cantonal administration has set itself the goal of acting as a role model in climate protection. Despite initial progress, it is clear that energy consumption for heating and hot water in cantonal buildings has only been reduced by 2 per cent. More than half of the heating energy is still obtained from fossil fuels. CO2 emissions from the combustion of these fuels have remained virtually unchanged since 2016, indicating a need for additional action.

    Adjustments to energy requirements and future steps
    The Government Council has submitted measures that can be implemented quickly for consultation in order to increase the use of renewable energies. Among other things, these relate to the replacement of heating systems and the generation of self-generated electricity in new buildings. One example is the requirement that a renewable energy system should always be used in future when replacing heating systems in canton-owned buildings.
    Overall, it is clear that the canton of Schaffhausen is on the right track, but that targeted measures are still required to accelerate the transition to a climate-neutral future.

  • Solar energy on rails: new concept

    Solar energy on rails: new concept

    Sun-Ways wants to transform railway tracks into solar power plants. The idea is to install solar modules between tracks in such a way that they can be easily removed again, for example for track repairs. The Federal Office of Transport has now given the green light for the first pilot project, according to the start-up from Ecublens, which was founded in 2023.

    Sun-Ways will now be able to test its systems on a 100-metre stretch of track near Buttes station from spring 2025. The 48 solar modules will be installed by Scheuchzer, a track builder and manufacturer of track construction systems based in Bussigny VD.

    The installation and connection to the grid will be carried out by Viteos, a provider of renewable energies based in Neuchâtel, and DG Rail, a specialist in railroad power supply. The system will be able to generate up to 16,000 kilowatt hours per year over an area of 100 square meters. The partners in the pilot project are bearing the costs of 585,000 Swiss francs.

    Thanks to a special development from Scheuchzer, the solar systems from Sun-Ways can be installed both manually and automatically on the track bed between the tracks and easily removed again. The Scheuchzer machine can now lay up to 1000 square meters of solar modules per day. In Switzerland alone, with its 5000 kilometers of track systems, Sun-Ways expects a potential of 1 terawatt hour of electricity per year, enough to supply 300,000 households.

    The town of Aigle VD has already approved another plant, which is to be built on private tracks over a length of 1500 kilometers. Sun-Ways is also already in talks with the French state railroads SNCF and with partners in Spain, Romania and South Korea about further pilot projects.

  • Negative emissions for a climate-neutral future

    Negative emissions for a climate-neutral future

    Energie 360° is opening up the market for permanent CO2 removal to interested companies and private individuals. According to a press release, the Zurich-based energy supplier is now enabling them to buy certificates for negative emissions online.

    The physical removal of CO2 takes place in the pyrolysis plant of Energie 360° subsidiary Bioenergie Frauenfeld. There, CO2 is extracted from waste wood with the help of renewable energies and bound as pure carbon. This is mixed with an earth substrate, for example, and can thus be permanently removed from the atmosphere. Bioenergie Frauenfeld produces around 3500 tons of biochar per year. This corresponds to over 10,000 tons of stored CO2.

    One of the first customers for the certificates is Zürcher Kantonalbank(ZKB). “Our goal is to achieve net zero in our operations by 2030,” ZKB CEO Urs Baumann is quoted as saying in the press release. “In order to permanently remove some of our unavoidable CO2 emissions from the atmosphere, we are purchasing negative emissions certificates from Energie 360°’s Frauenfeld bioenergy plant.”

    Energie 360° also invested in two German start-ups in September in order to develop products for the Swiss market with them. Ucaneo Biotech in Berlin has developed an electrochemical process for the direct removal of CO2 from the air. Planeteers in Hamburg removes stored CO2 from seawater and can thus produce mineralized water and improve the acid-binding capacity of the sea.

  • Future-oriented urban development in Bern

    Future-oriented urban development in Bern

    Wankdorfcity 3 is located on a 34,000 square meter site in the north of Bern. An urban living space is being created here that goes beyond mere residential use. With this project, the real estate developer IMMOFONDS is creating a dense district that offers both living space and contact points for commercial and leisure activities. The direct connection to public transport creates a lively ecosystem characterized by interaction and exchange.

    Efficient planning and rapid approval
    The complexity of the planning for this project required innovative approaches and close cooperation between the responsible architects, urban planners and authorities. Gabriela Theus, Managing Director of Immofonds Asset Management AG, explains: “The efficient processing by the City of Bern and the collaborative partnership between all parties involved led to approval in accordance with building law without any objections – a record-breaking success throughout Switzerland.”

    Social and ecological sustainability
    Social sustainability is a key component. The creation of meeting places, communal spaces and outdoor areas will encourage interaction between residents. The planned urban garden and the varied open spaces characterize a place of togetherness.

    Diversity in living space
    In order to accommodate different lifestyles, the project offers a variety of living arrangements. From small apartments and tiny houses to family-friendly townhouses and multifunctional communal areas – there is something for every target group. This diversity ensures a lively district that meets the needs of its users.

    Innovative strength in urban development
    Wankdorfcity 3 is based on the innovative concept of the sponge city, which promotes sustainable water management in urban areas. Landscape architect Maurus Schifferli explains that rainwater is stored in special systems so that it can be released again in a targeted manner. This principle helps to regulate the local climate and shows how modern urban planning can combine resource conservation with aesthetics.

    Outlook for the next steps
    The final building permit marks the start of the implementation phase. The apartments and the associated services and commercial space will be ready for occupation in stages from 2027. In the coming years, Wankdorfcity 3 will not only contribute to the quality of life in Bern, but will also serve as an innovative example of modern urban development throughout Switzerland.

    This forward-looking project signals a new era of urban living that combines intergenerational living, inclusivity and sustainability.

  • Buildings as carbon sinks

    Buildings as carbon sinks

    The construction industry is one of the largest CO2 emitters in the world. However, projects such as “Beyond Zero” and the “Mining the Atmosphere” initiative could turn the tide. The aim is not only to reduce the harmful greenhouse gas, but to actively bind it in building materials. These materials, which are being tested in the new NEST unit, could revolutionise concrete and insulation materials and have the potential to make the construction industry climate-neutral or even CO2-negative.

    Technology undergoing practical testing
    Nathalie Casas from Empa explains that “negative emissions technologies” (NET) are the key to achieving climate targets: “We need to remove excess CO2 from the atmosphere in order to achieve the 1.5-degree target. NETs, which already work in the laboratory and are now being used in the construction industry, will help us achieve this.” Casas emphasises the urgency of taking action as emissions continue to rise.

    Sustainability in the construction industry
    Corinne Reimann from Implenia sees NET as a great opportunity for the construction industry: “The new materials will finally enable us to make decisive progress in the area of sustainability. The industry has enormous leverage here, but also challenges. Price and acceptance will be crucial.” Reimann emphasises that the functionality and cost-effectiveness of new materials must be ensured in order to enable their widespread use.

    The contribution of architects and planners
    Christoph Kellenberger, co-founder of OOS, sees the early involvement of architects and planners as a decisive factor: “With our knowledge, we can help develop the right building materials from the outset and integrate them into construction practice. We also need to publicise the potential of CO2-storing materials in the industry and show what effects can be achieved with them.” For Kellenberger, the key to success lies in transparent knowledge transfer and practical solutions.

    Political framework conditions and social responsibility
    In addition to technological innovation, the construction industry also requires political and economic framework conditions. According to Casas and Kellenberger, clear cost transparency is necessary in order to promote the widespread use of NET. CO2 emissions must be priced fairly and subsidies could help to offset the initial higher costs of the new materials. “The transformation will only succeed if everyone pulls together – politics, business and society,” says Casas.

    The “Beyond Zero” project shows that it is possible to turn buildings into carbon sinks. However, this requires not only technological solutions, but also the will of politics, business and society to break new ground. The construction industry has the opportunity to develop from one of the largest CO2 emitters into a pioneer of the climate transition – and the potential to do so already exists today.

  • Findings from the Healthy Buildings Barometer 2024

    Findings from the Healthy Buildings Barometer 2024

    The Healthy Buildings Framework presented in the Barometer provides a comprehensive definition of healthy buildings that covers five interrelated dimensions: improving mental and physical health, focussing on human needs, sustainable construction, resilience and flexibility, and empowering people through knowledge. These dimensions provide a clear guideline for the planning and implementation of construction and refurbishment projects.

    The study emphasises that buildings must be considered not only from an energy perspective, but also from a health and social perspective in order to meet the needs of users and at the same time tackle climate challenges.

    Switzerland as a pioneer in building refurbishment
    The study places particular emphasis on Switzerland, which is playing a pioneering role in the building sector with a progressive refurbishment rate and innovative solutions. However, the barometer points out that the renovation rate of 0.2 per cent across Europe is still far too low to achieve the climate targets. In future, health aspects such as the indoor climate and adaptability to changing climatic conditions must be given greater consideration in order to both improve people’s quality of life and protect the environment.

    Focus on health and well-being
    According to the Healthy Buildings Barometer 2024, people spend up to 90 per cent of their time indoors, which makes the quality of indoor air and the availability of daylight key factors for health. In Switzerland, 7.3 per cent of people already rate their homes as too dark. Daylight and good indoor air quality are crucial for the well-being and performance of building users. The barometer makes clear recommendations here: The targeted use of natural light sources and effective ventilation systems should promote health and well-being.

    Specialists as a crucial resource for the future
    The shift towards healthy and sustainable buildings requires specialised professionals, but their numbers are stagnating. In order to transform the building stock and implement the urgently needed refurbishment measures, more specialists must be trained and demographic change must be taken into account. The fifth dimension of the framework, “Empowering people through knowledge”, emphasises the importance of education and training in this area.

    The Healthy Buildings Barometer 2024 provides a comprehensive guide to making buildings healthier and future-proof. With clear recommendations for politicians, the construction industry and decision-makers, the study shows that only a holistic approach can meet the challenges of the building sector. Switzerland is playing a pioneering role here, but there is still much to be done across Europe to sustainably improve the building stock.
