  • 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.

  • New ultra-thin film for interference-free 5G and 6G

    New ultra-thin film for interference-free 5G and 6G

    With the new film made from a special composite material, KIMS is demonstrating how electromagnetic interference in communication systems can be effectively minimised. The film, which is only 0.5 mm thick, absorbs more than 99% of electromagnetic waves in frequency ranges such as 5G, 6G and WiFi. This shielding technology avoids disruptive reflections and offers unrivalled freedom from interference. An advantage that could further optimise the use of modern communication devices and radar systems.

    Absorption instead of reflection
    Conventional shielding materials often rely on reflection, but this is only partially effective. The new type of film, on the other hand, absorbs electromagnetic waves in a targeted manner and thus ensures a high level of interference immunity. This approach prevents waves from bouncing back and interfering with neighbouring systems. The technology is based on a unique crystal structure and a magnetic composite layer that precisely filters frequencies and ensures maximum absorption.

    Flexible and dimensionally stable for a wide range of applications
    The developed film shows high flexibility and dimensional stability, even after thousands of folds. These properties make it ideal for flexible and portable devices such as smartphones and electronics. It also offers reliable shielding and high durability for roll-up screens and other flexible technologies. The film remains dimensionally stable and functional even in demanding applications. Ideal for use in modern, portable devices.

    Optimisation through carbon nanotubes
    A thin carbon nanotube film on the back of the film further increases the shielding performance. With an absorption coefficient of 99.9%, the film ensures that electromagnetic waves do not penetrate to the outside and that interference in various mobile and autonomous applications is minimised. This innovative combination of materials creates reliable shielding, which is particularly in demand in areas with high sensitivity to electromagnetic interference.

    With its high absorption and flexibility, the new KIMS film offers an ideal solution for minimising interference in modern communication technology. It enables better freedom from interference in 5G and 6G networks and could bring ground-breaking improvements in autonomous systems and portable devices – a promising development for future digital infrastructure.

  • 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.

  • Construction work on the extension of the ZHAW has begun

    Construction work on the extension of the ZHAW has begun

    Building Director Martin Neukom, Education Director Silvia Steiner and ZHAW Rector Jean-Marc Piveteau gave the go-ahead for the construction work to expand and modernise the School of Engineering at the ZHAW on 13 September. The ZHAW is one of the leading universities in Switzerland with over 14,000 students, according to a press release. However, some of the existing buildings on the site of the former technical centre in Winterthur no longer meet today’s requirements. In addition, the number of students continues to grow. Campus T will therefore be modernised and expanded in several stages over the next few years.

    In the first construction phase, two new five-storey laboratory buildings will be built behind the historic technical centre. They will provide urgently needed space for teaching, research and development. Various test rooms as well as a publicly accessible canteen and cafeteria will be created there. The new buildings will be connected to the district heating network of the city of Winterthur and equipped with photovoltaic systems.

    As part of the first construction phase, the Eulach will also be ecologically upgraded with a public, near-natural park and flood protection will be expanded, according to the press release. Two new bridges will connect the old town and Campus T with the Büelrain cantonal school and the surrounding residential neighbourhood.

    The existing TB building will be dismantled by November. At the same time, the excavation pit for the smaller TT laboratory building will be dug. Work will then begin on the shell of the first new building, which is scheduled for completion in 2027. The second new building should be ready for occupancy in 2029.

  • Innovative drone research

    Innovative drone research

    At the centre of this research is the “DroneHub”, a state-of-the-art laboratory that is being built on the Empa campus in Dübendorf. This unique research building makes it possible to test drones under real-life conditions – a significant development for both the construction industry and environmental sciences. In the future, drones could repair buildings before damage escalates or even save lives by monitoring dangerous areas before the fire brigade.

    The spirit of innovation driving this project is evident in the extraordinary combination of environmental monitoring and construction robotics. The new drone models can place sensors in trees or collect water samples from the depths of oceans and lakes – essential data to monitor the health of our ecosystems.

    However, Kovac and his international team are going even further. With aerial additive manufacturing (AAM) technology, drones could be able to print building materials from the air. This technology has the potential to fundamentally change the way buildings are maintained and constructed while utilising resources more efficiently.

    Redefining building maintenance
    The “DroneHub” provides a protected space for the development and testing of robots and drones that can autonomously perform tasks such as building maintenance and environmental monitoring. The DroneHub’s unique AAM wall simulates real building surfaces on which the drones demonstrate their repair and maintenance capabilities. These technologies are particularly relevant for the property sector, where safety and efficiency in maintenance are becoming increasingly important.

    This collaboration between Empa and EPFL not only opens up new perspectives for robotics, but also for the future of the property industry. Drones that carry out inspections and repairs autonomously could revolutionise the way buildings are maintained. For managers and professionals in the property and location development sector, this project offers an exciting look at the future of the industry – innovative, sustainable and with a clear focus on efficiency and safety.

  • Roche opens new centre for pharmaceutical research

    Roche opens new centre for pharmaceutical research

    A significant milestone has been reached at Roche’s headquarters in Basel. The inauguration of the new Pharma Research and Early Development Centre (pRED). The centre, which offers 1,800 state-of-the-art workstations for laboratory and office work, brings together experts from various fields of research. The aim is to increase the efficiency of research and development through close collaboration. Federal Councillor Guy Parmelin also attended the opening ceremony, which emphasises the national importance of this project.

    With the new pRED Centre, Roche is pursuing a clear vision of pooling expertise from areas such as chemistry, biology and data science in order to drive forward pioneering innovations. Thomas Schinecker, CEO of the Roche Group, emphasised the central role of the centre in the company’s global innovation network. “This centre will not only improve the efficiency of our research, but also help us to achieve the greatest possible benefit for patients worldwide.”

    Investing billions in the future
    The investment in the pRED Centre is part of Roche’s long-term commitment to the Basel site. Since 2009, the company has invested 4.6 billion Swiss francs in the expansion of the site. With the new four buildings – including two high-rise laboratory buildings, an office complex and a congress centre – Roche is sending another strong signal for the future.

    And this is just the beginning: a further 1.2 billion Swiss francs are being invested in modernising and expanding the site, which will strengthen Basel’s role as a global centre for pharmaceutical research and development in the long term.

    With the opening of the new pRED Centre, Roche is not only investing in its own innovative strength, but also in strengthening Basel as a business location. This billion-euro investment is a clear signal that the pharmaceutical company intends to further expand its leading role in global research and development – a significant step both for the industry and for the region.

  • Research into earthquake safety for multi-storey buildings

    Research into earthquake safety for multi-storey buildings

    Empa researchers are conducting practical tests on the stability of multi-storey timber buildings against wind gusts and minor earthquakes. According to a press release, the results should help to optimise construction planning, especially for increasingly popular, mostly four- to five-storey timber buildings, and increase building safety. They should also help to increase the competitiveness of wood as a sustainable building material for multi-storey buildings.

    The construction industry is therefore reliant on data that is as practical as possible in terms of stiffness, basic vibration times and damping. Such data can be used to ensure that exactly the right amount of material is used in the right places.

    The group from the Engineering Structures research department is using a hydraulic horizontal oscillator, known as a shaker, for its investigations on a real object. It can set up to 1000 kilograms of vibrating mass in motion in a controlled manner. According to the information provided, the data obtained so far now delivers results on the dynamic properties of a multi-storey timber construction using the usual construction method in this country.

    An open day on 14 September 2024 will demonstrate how the shaker is used to set a structural model in motion, which can occur during earthquakes. The model will be used to visualise how the weight and stiffness distribution in the structure influences its vibration behaviour.

  • New findings on the stiffness of timber structures

    New findings on the stiffness of timber structures

    Timber buildings are experiencing an upswing in Switzerland. With their sustainability and aesthetics, they are becoming increasingly popular, even for multi-storey buildings. But how can it be ensured that these structures can withstand the forces of wind and earthquakes? This is a question that occupies building researchers, especially when planning timber buildings up to 75 metres high. This is because the right bracing and supporting structures must be in place to ensure that timber buildings remain stable even under extreme conditions.

    Research in this field has made considerable progress in recent years. One particularly exciting tool is the shaker, a two-tonne device that is used in Empa’s largest laboratory in Dübendorf. The shaker simulates earthquakes and strong winds by causing building models to vibrate. In this way, the vibration behaviour of the buildings is examined under real conditions and the models for calculating stiffness are refined.

    The shaker in action
    For the open day on 14 September 2024, the shaker will be demonstrated in Empa’s construction hall in Dübendorf. This is not just about scientific research – visitors will get a direct insight into the work of the engineers. René Steiger, Pedro Palma and Robert Widmann, structural engineers at Empa, will give an impressive demonstration of how the shaker causes a structural model to vibrate, thereby analysing the behaviour of the weight and stiffness distribution.

    This research is of great importance, as ever taller timber buildings are being erected in Switzerland. While most buildings remain in the 4- to 5-storey range, projects with more than 20 storeys demonstrate the potential of timber as a building material. However, ensuring the stability of such buildings requires precise calculations and practical tests such as those carried out with the Shaker.

    Complex requirements for timber construction
    The challenge with multi-storey timber buildings lies not only in the load-bearing capacity of the walls, but also in the balance between rigidity and flexibility. Whilst thicker components and additional load-bearing walls are often seen as a solution, they can lead to increased costs. Sometimes it is even more favourable if a structure reacts flexibly to earthquake shocks to a certain degree. These nuances must be taken into account in the computer calculations, and this is precisely where the shaker provides valuable data from practice.

    The experiments in the construction hall and on real buildings, such as in Oberglatt in the canton of Zurich, show how the supporting structure gains rigidity during various construction phases. For example, the researchers were able to observe exactly how the load-bearing capacity of the buildings changed when load-bearing walls, non-load-bearing walls and windows were installed.

    Practical data for planners and architects
    For a long time, planners relied on mathematical approximations to determine the dynamic properties of timber structures. These values were often based on tests from Japan and North America, but due to different building regulations and requirements, they are not readily transferable to Switzerland. This is where the work of the Empa researchers comes in: The shaker and the measurements on real buildings provide precise data on stiffness and damping that is specifically tailored to local building requirements.

    This provides construction engineers and architects with reliable information to optimise their planning and use wood as a material efficiently and sustainably. The knowledge gained will help to further develop standards and guidelines and strengthen timber construction as a competitive solution for multi-storey buildings.

    Wood as a building material of the future
    Empa’s research results show that wood has enormous potential as a building material for multi-storey buildings. The use of the shaker provides construction engineers and architects with practical data that makes it possible to design timber buildings more safely and efficiently. By combining modern technology and scientific expertise, Empa is making a decisive contribution to advancing timber construction in Switzerland and establishing it as a sustainable alternative in the construction industry.

  • Breakthrough in quantum computing technology

    Breakthrough in quantum computing technology

    Quantum computers could fundamentally change our understanding of problem solving and calculations in the near future. However, the technology still faces a crucial hurdle – the error-proneness of quantum bits, which are the central building blocks of quantum computers. Google has now reached a significant milestone with its latest success in quantum error correction.

    Researchers at Google’s Quantum Artificial Intelligence Lab have managed to combine 97 error-prone quantum bits into one logical quantum bit that has a significantly lower error rate. This is an important step on the way to error-tolerant quantum computers that could perform complex calculations in the future.

    Challenges of quantum error correction
    The biggest challenge for quantum computers is the high probability of errors during computing operations. In current systems, the probability of error is between 0.01 and 1 per cent, depending on the operation. As quantum computers potentially require thousands of calculation steps, this means that the possibility of errors increases exponentially. Without effective error correction, the advantages of quantum computers would be almost impossible to utilise in practice.

    The Google researchers developed a method in which quantum information is distributed across several quantum bits. Measurement bits ensure the stability of the states without directly changing the information. This redundant approach, which is also used in classical computers, led to the formation of a more robust logical quantum bit.

    A decisive advance – but not yet the goal
    Google was able to achieve a critical error threshold by reducing the error rate of a 97-qubit quantum bit system to half that of a 49-qubit system. This progress is highly rated by experts and can be compared to the groundbreaking results of 2019, when Google demonstrated for the first time that quantum computers can outperform conventional computers in certain tasks.

    Despite this promising development, quantum research still faces huge challenges. The next step is to perform basic computing operations with the stabilised logical quantum bits. In the long term, these stable bits will be used to enable complex and fault-tolerant calculations.

    Fault-tolerant quantum computers and their application
    Although the progress made so far is impressive, there is still a long way to go before quantum computers are able to solve really complicated problems. It is estimated that around 1457 physical quantum bits are needed to achieve an error rate of 1 in 1,000,000 – a minimum requirement for solving simple problems.

    For complex challenges such as breaking modern encryption methods, even thousands of logical quantum bits are required. Therefore, further progress in quantum error correction and more efficient algorithms are urgently needed to reduce the required number of physical quantum bits.

    A clear path ahead
    The current results from Google and other research groups form a solid basis for the development of the quantum computers of the future. While many technical hurdles remain, recent advances are making the goal of a powerful, fault-tolerant quantum computer more tangible. Whether and how the technology will become established in practice remains to be seen, but the outlook is now clearer than ever before.

  • Study shows opportunities for façade greening and solar panels

    Study shows opportunities for façade greening and solar panels

    As part of the GreenPV project, a research team from Lucerne University of Applied Sciences and Arts has developed innovative solutions for the design of building façades. The aim was to explore the potential of photovoltaic systems (PV) and greenery in order to meet the increasing challenges posed by global warming. A brochure specially developed for planners and building owners summarises the findings and recommendations of the project.

    The importance of this research becomes clear when you look at the forecasts of the National Centre for Climate Services: The average annual temperature in Switzerland could rise by up to 5.4 degrees by the end of the 21st century. This will not only significantly increase energy requirements, particularly for cooling, but will also affect comfort levels in buildings. Photovoltaic systems can supply energy precisely when it is needed most, namely when the sun is shining intensely. At the same time, green façades offer a sensible alternative in urban areas where new green spaces are scarce.

    Façades as untapped potential
    “While the benefits of PV systems and greenery are already increasingly being used on roofs, façades have so far remained largely unused,” explains Dr Silvia Domingo, researcher at HSLU. Yet façades offer an excellent opportunity for energy generation and greening without taking up additional space. PV systems on south-facing façades are particularly efficient in the cold season, as they can make optimum use of the low angle of inclination of the sun.

    However, the study also shows that there are obstacles that stand in the way of a wider application of these technologies. These include financial challenges, a lack of guidelines and concerns about fire safety. These factors often cause uncertainty among building owners. To counteract this, the research team has produced a brochure with practical recommendations for the use of PV systems and greenery on façades.

    Visual aspects and functional synergies
    Another obstacle identified by Dr Domingo is the aesthetic perception of solar panels on building façades. Black solar panels often do not meet the visual expectations of building owners. However, research shows that solar panels in different colours and textures could also be available in the future without any significant loss of efficiency.

    In addition to PV systems, green façades offer numerous advantages that go far beyond the cooling effect. They contribute to biodiversity, improve air quality, reduce sound propagation and promote rainwater retention. These benefits are particularly important in densely built-up urban areas, where they can significantly improve the quality of life.

    The combination of greenery and PV systems
    The HSLU study shows that greenery and PV systems on façades can often be combined well in order to utilise synergies. While PV systems on unshaded, higher façade areas ensure maximum energy generation, green areas near the ground have a cooling and noise-absorbing effect. This combination contributes to a more pleasant neighbourhood climate and climate-friendly electricity production.

    Completion of the GreenPV project
    The GreenPV project, which started in December 2021 and ran until mid-2024, was funded by a broad network of supporters, including the Swiss Federal Office of Energy (SFOE) and various foundations. The project team, led by Gianrico Settembrini, gained valuable insights, which are recorded in a brochure and are now available to planners, building owners and interested parties.

    With the results of the GreenPV project, the HSLU is making an important contribution to sustainable development in the construction industry and demonstrating how greenery and solar panels on façades can be combined to effectively meet the challenges of climate change.

  • 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.

  • No complex thinking skills with ChatGPT & Co.

    No complex thinking skills with ChatGPT & Co.

    The research, which will be presented at the annual meeting of the Association for Computational Linguistics in Bangkok, concludes that large language models such as ChatGPT show no evidence of the development of sophisticated or planned thinking. Instead, these models only demonstrate the ability to respond to simple instructions. This disproves the widespread assumption that AI models could exhibit increasingly intelligent behaviour through scaling.

    Background to the study
    The study, led by Prof Dr Iryna Gurevych from TU Darmstadt and Dr Harish Tayyar Madabushi from the University of Bath, investigated so-called “emergent capabilities” of AI models. These capabilities, which were observed with increasing model size and data volume, raised both hopes and fears regarding the future development of artificial intelligence. However, current research shows that these abilities are due to simple learning effects rather than complex, independent thinking.

    Implications for the future of AI use
    The results of the study have significant implications for the use of AI systems. Prof Gurevych warns against relying on the models to solve complex tasks without human support. She emphasises that users should provide explicit instructions and examples in order to use the systems effectively. In addition, the tendency of models to produce plausible-sounding but incorrect results remains a challenge.

    Focus on future risks
    Although the study shows that LLMs do not develop complex thinking skills, this does not mean that AI does not pose a threat. Prof Gurevych calls for research to focus on the real risks of AI models, particularly their potential to generate fake news. The findings of the study provide a valuable basis for better understanding the actual capabilities of AI models and making their use safer in practice.

  • ZHAW validates yield calculations for alpine solar systems

    ZHAW validates yield calculations for alpine solar systems

    Researchers at the ZHAW have verified the accuracy of the PVSyst software’s calculations on the yield of alpine solar plants. The Swiss Federal Office of Energy recommends this software as part of the expansion of alpine solar plants, the ZHAW explains in a press release. The results of the research showed “that the approach proposed by the federal government makes sense and that the yields tend to be underestimated”, the press release explains.

    For the validation, the ZHAW researchers carried out a large number of measurements on the Totalp in Davos GR in the winter months of 2023/24 using a flexible, multi-row miniature system. The measurement data largely matched the data collected at the same time from the existing test facility at the same location. In contrast, the yields calculated using the PVSyst simulation tended to be lower across the board.

    The researchers attribute this to the albedo values from Meteonorm used by the software. Albedo is a value for the proportion of sunlight reflected from the ground. At the same time, the research was able to show that backside irradiation on a bifacial solar panel increases the yield by around 25 to 35 per cent.

  • Solid-state batteries made of rock

    Solid-state batteries made of rock

    Researchers at DTU have developed an innovative material that could replace lithium in batteries: Potassium silicate, a widely available mineral extracted from common rock. According to the scientists, this solid-state battery could be an environmentally friendly, efficient and safe alternative to current lithium-ion batteries in around ten years’ time.

    Challenges of current lithium-ion batteries
    Lithium-ion batteries currently used in electric cars have their limits. The capacity, safety and availability of lithium are limited. The mining of lithium is not only expensive, but often takes place under questionable conditions. The metal is also relatively rare, which makes scaling difficult and hinders the transition to sustainable electromobility.

    In view of the growing interest in electric cars, the need for new, powerful and more environmentally friendly batteries is increasing. This requires the development of new materials for the anode, cathode and electrolyte as well as innovative battery concepts. Researchers around the world are working to find these new “recipes” to reduce carbon emissions from the transport sector.

    The breakthrough with potassium silicate as a solid-state electrolyte
    Researcher Mohamad Khoshkalam from DTU has patented a superionic material based on potassium silicate. This mineral is one of the most common on earth and can be found in ordinary rocks. A major advantage of this new material is its insensitivity to air and moisture, which makes it ideal for use in batteries.

    The milky-white, wafer-thin material can conduct ions at around 40 degrees Celsius and remains resistant to moisture. These properties make the scaling and production of future batteries much easier. As the material can be produced in an open atmosphere and at room temperature, it significantly reduces production costs. In addition, it does not require expensive and environmentally harmful metals such as cobalt, which are used in current lithium-ion batteries.

    Potential and prospects
    The development of the potassium silicate solid-state battery could represent a significant turning point in the electric car industry. By utilising widely available, environmentally friendly materials, the dependence on rare and environmentally harmful metals could be reduced. This would not only reduce production costs, but also increase the sustainability and efficiency of batteries.

    The DTU researchers are confident that their discovery can be brought to market maturity in the coming years. If this is successful, solid-state batteries made of rock could have a decisive impact on the future of electromobility and make a major contribution to reducing carbon emissions.

    This ground-breaking technology proves once again that innovative approaches and research results are crucial to mastering the challenges of the modern world and finding sustainable solutions.

  • 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.

  • Intergenerational living as a challenge and an opportunity

    Intergenerational living as a challenge and an opportunity

    Gemeinschaftliche Wohnformen gewinnen zunehmend an Bedeutung aufgrund veränderter Lebens- und Familienstrukturen sowie einer zunehmenden Mobilität und demografischen Alterung. Der intergenerationelle Austausch wird dabei als positiv für die physische und emotionale Befindlichkeit angesehen und kann dazu beitragen, den Umzug in Alters- und Pflegezentren zu verzögern oder zu verhindern.

    Studie zu Generationenwohnprojekten
    Forschende des ETH Wohnforum – ETH Case, der Berner Fachhochschule und age-research.net haben sechs Generationenwohnprojekte hinsichtlich ihrer Chancen und Grenzen untersucht. Diese Projekte unterscheiden sich in Grösse, Trägerschaften, Organisationsformen und architektonischen Gestaltungen. Vier der Projekte richten sich an Menschen aller Altersgruppen, zwei sind speziell für Menschen ab 50 Jahren konzipiert.

    Das Forschungsprojekt «Generationenwohnen in langfristiger Perspektive – von der Intention zur gelebten Umsetzung» untersucht die konzeptuelle, organisatorische und alltägliche Entwicklung des generationenübergreifenden Wohnens. Die Ergebnisse zeigen, dass solche Wohnprojekte für gemeinschaftsorientierte Menschen eine gute Alternative zu herkömmlichen Wohnformen darstellen. Diese Projekte schaffen bezahlbaren und bedürfnisgerechten Wohnraum für verschiedene Generationen und fördern Unterstützung und Gemeinschaftlichkeit im Wohnen. Sie senken das Risiko sozialer Isolation und unterstützen soziale Teilhabe. Diese Wohnprojekte können auch als Modelle für eine umfassende, integrierte Stadtplanung dienen und zur Entwicklung lebendiger Quartiere beitragen.

    Empfehlungen für Trägerschaften und Behörden
    Der Bericht enthält konkrete Handlungsempfehlungen für Trägerschaften und die öffentliche Hand. Wichtig ist eine angepasste Partizipation während der gesamten Projektphase, um intergenerationelle Begegnungen zu ermöglichen. Gemeinschaftlich genutzte Räume sollten niederschwellig zugänglich sein, und die Wohnumgebung muss über nahe und gut erreichbare Versorgungsstrukturen und Verkehrsanbindungen verfügen.

    Für den Bund, die Kantone und die Gemeinden stehen verschiedene Massnahmen zur Unterstützung des Generationenwohnens zur Verfügung. Gemeinden könnten bei der Vergabe von Bauland generationsübergreifende Wohnprojekte bevorzugen. Förderprogramme wie zinsgünstige Darlehen, Investitionszuschüsse oder Steuererleichterungen könnten ebenfalls helfen. Eine enge Zusammenarbeit von Behörden, gemeinnützigen Bauträgern, Architektur- und Planungsbüros sowie sozialen Fachpersonen ist wesentlich. Auch Architekturwettbewerbe mit interdisziplinären Planungsteams und Jurys können wertvolle Impulse geben.

    Zukunftsfähige, aber anspruchsvolle Wohnform
    Trotz ihrer vielen Stärken ist die Umsetzung von Generationenwohnprojekten anspruchsvoll. Sie erfordert eine bedürfnisgerechte und partizipative Planung und Realisierung, die von Trägerschaften und Gemeinden ein höheres Mass an Beteiligung verlangt als konventionelle Wohnprojekte. Generationenwohnprojekte reagieren flexibel auf sich ändernde Anforderungen und Bedürfnisse in einer vielfältigen Gesellschaft.

    Das umfangreiche Projekt wurde neben dem BWO auch durch die Age Stiftung, die Beisheim Stiftung, die Walder Stiftung sowie das Max Pfister Baubüro AG gefördert.

  • Basel receives multi-billion euro immune research institute

    Basel receives multi-billion euro immune research institute

    The Botnar Foundation has donated one billion Swiss francs to establish the Botnar Institute of Immune Engineering (BIIE). This institute will be located in Basel, more precisely in Allschwil, and aims to develop novel immune-based solutions for the diagnosis, treatment and prevention of diseases. The BIIE is being set up in collaboration with the University of Oxford and ETH Zurich, with other international partners to follow.

    Strategic choice of location and expansion plans
    The research centre in Basel was able to prevail over renowned locations in the USA, England, Israel and Singapore. By 2027, the BIIE will move into its own building in the Switzerland Innovation Park Basel Area in Allschwil, which is being designed by Herzog & de Meuron. For the time being, the institute is housed in the Department of Biosystems Science and Engineering at ETH Zurich in Basel. It is planned that a total of 300 employees, including scientists and support staff, will work at the institute.

    Priorities and international collaborations
    BIIE will focus on the development of computer tools and immune-based solutions. Together with the University of Oxford, the Basel-Oxford Centre of Immune Engineering will be established, which will include professorships and training programmes for students. This collaboration will advance basic and clinical research, particularly for children and adolescents in poorer countries.

    Leading personalities and administration
    Stephen Wilson, former Chief Operating Officer of the La Jolla Institute for Immunology, will serve as CEO of BIIE. Sai Reddy, Professor of Systems and Synthetic Immunology at ETH Zurich, will serve as Scientific Director. Georg Holländer, an expert in molecular developmental immunology with professorships at the University of Basel, ETH Zurich and the University of Oxford, will assume the position of Global Engagement Director.

    Significant upgrade for Basel as a research centre
    The establishment of the BIIE represents a significant upgrade for Basel as a research centre. The site complements existing research groups at the D-BSSE and the Department of Biomedicine at the University of Basel and strengthens the region, which is already home to over 40 biotech and pharmaceutical companies in the field of immunology.

    Huge benefit for the Basel region
    “The BIIE will bring together a critical mass of researchers who are all experts in different aspects of immune engineering. The combination of their strengths and perspectives should result in a sum that is greater than its parts,” explains Stephen Wilson. Conradin Cramer, President of the Government of the Canton of Basel-Stadt, emphasises the importance of the institute for the region: “Basel as a strong economic region with a great philanthropic tradition will be further strengthened by the BIIE.”

    Christof Klöpper, CEO of Basel Area Business & Innovation, sees the BIIE as an enormous gain for the region: “Our life sciences location will not only be expanded by an important field of research, but will also strengthen its position on the global map of the most important research locations.”

    The generous donation from the Botnar Foundation and the collaboration with leading international institutions such as the University of Oxford and ETH Zurich position the Botnar Institute of Immune Engineering as a central institution in immune research. The new institute will further establish Basel as a top global centre for life sciences and enable significant advances in immune-based diagnostics and therapy.

  • Cement revolution thanks to mother-of-pearl structure

    Cement revolution thanks to mother-of-pearl structure

    Unlike glass, wood and steel, cement is naturally brittle and not very flexible without reinforcements. This considerably limits its possible uses in load-bearing structures. Although there are already methods for improving the fracture toughness and ductility of cement, for example through polymer, glass or metal reinforcements, these only slightly increase energy absorption and fracture resistance.

    A composite material modelled on mother-of-pearl
    The Princeton University team found that alternating layers of thin polymer and patterned cement paste increase ductility. The composite material developed mimics the structure of mother-of-pearl, a substance found in certain shells and known for its strength and flexibility. Mother-of-pearl consists of over 95% calcium carbonate and up to 5% organic material. This unique combination gives mother-of-pearl its remarkable mechanical resistance.

    Mechanisms of the mother-of-pearl structure
    Mother-of-pearl is a biomineral consisting of aragonite platelets connected by a soft biopolymer. This 3D brick mortar structure allows the platelets to slide and deform, absorbing energy and increasing toughness. This synergy between the hard and soft components is crucial for the remarkable mechanical properties of nacre.

    Applying the principles to cement composites
    The Princeton University researchers used conventional building materials such as Portland cement and polymers to develop a similar composite. They layered cement paste boards with polyvinyl siloxane, a flexible polymer, to create multi-layered beams. These were tested for crack resistance in a notched three-point bending test. The results showed that these composites achieved 17 times higher fracture toughness and 1791 per cent higher ductility compared to solid cement.

    Future prospects and optimisation
    The researchers plan to explore different soft materials for more resistant infrastructures and to optimise the groove shapes for better defect integration. In addition, production methods are to be further developed using integrated lamination laser processes or additive manufacturing. These advances could revolutionise the construction industry and significantly expand the use of cement in load-bearing structures.

    The newly developed cement composite, inspired by the structure of mother-of-pearl, offers a promising solution for improving the mechanical properties of cement. With its exceptional crack resistance and ductility, this composite represents a significant innovation that has the potential to transform the construction industry.

  • New building for health and biomedical research inaugurated

    New building for health and biomedical research inaugurated

    ETH Zurich has inaugurated its latest new building. The university’s health sciences and biomedical engineering departments have moved into the Gloria Cube, the ETH announced in a press release. Specifically, the new laboratory and research building houses 16 research groups from the fields of exercise science and sport, rehabilitation and biomedical engineering as well as application-orientated, translational research.

    The new building on Gloriarank connects the ETH campus with the neighbouring residential buildings in the Fluntern district via continuous paths and a green area. The eight-storey building is also close to the University of Zurich and the University Hospital Zurich, making it “a natural address for interdisciplinary collaboration and translational research”, writes ETH. The transfer of research results into medical applications will be supported by a technology platform for medical human research set up in the Gloria Cube.

    The press release cites the development of new micro-active substances and new training methods to improve athletic performance and health as examples of future research to be conducted at the Gloria Cube. Another project is investigating the connection between pupil size and stress or mental well-being in general. The Gloria Cube has six seminar rooms and a learning centre for training. At the Skills Lab @ETH, medical students can teach each other basic medical skills.

  • Microbes as power stations

    Microbes as power stations

    In an unprecedented approach, Professor Boghossian’s team has transferred the properties of exotic microbes that live under anaerobic conditions and produce electricity as a by-product of their metabolism to the widespread and well-researched bacterium E. coli. This innovation could open the door to innovative applications in various industries.

    From nature to the lab
    The natural models of research, anaerobic microbes, utilise unique metabolic pathways to donate electrons to metals and thereby generate electricity. This mechanism was successfully implemented in E. coli, which predestines the bacterium for a wide range of technological applications. The transfer was complex and required the insertion of special proteins from the electrically active microbes in E. coli, which brought the ability to produce electricity into the laboratory.

    Possible applications and practical benefits
    The modified E. coli could be used in fuel cells, in wastewater treatment or as a biosensor. Of particular interest is the potential application in wastewater treatment, where the bacteria would not only help to purify the water, but could also generate electricity as a by-product. These dual benefits represent an attractive option for a circular economy where waste products are put to valuable use.

    Innovative research and industry collaboration
    Supported by EPFL’s innovative environment and the opportunity to work across disciplines, Professor Boghossian’s team continues to explore the practical applications of “electric” bacteria. The development of a prototype for the food industry in collaboration with a newly founded start-up demonstrates the commercial potential of this technology. This commitment offers not only scientific but also sustainable industrial solutions that can contribute to reducing the carbon footprint.

    Outlook and global interest
    While the technology is still in the development phase, there is already growing interest from both academia and industry. The work of Professor Boghossian and her team is a shining example of how innovative basic research can have a transformative impact on our energy future.

  • 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.

  • Impulses for Zurich’s future: The first day of the location

    Impulses for Zurich’s future: The first day of the location

    The first “Location Day” in the canton of Zurich brought together leading figures from business, research and politics to shed light on the attractiveness and future viability of the location. The focus was on discussing current challenges and developing strategies to strengthen the business and innovation location. Panels and workshops on topics such as technology, skilled workers, entrepreneurship, mobility and sustainability provided important impetus to further improve Zurich’s position in international comparison.

    A prior study on the attractiveness of the location provided the basis for in-depth discussions and highlighted Zurich’s strengths in the areas of education, economic power and quality of life, as well as areas with potential for improvement such as the labour market, innovation and infrastructure. In particular, the relevance of artificial intelligence for the technology location and the need for a stronger digital focus in the healthcare sector were emphasised. In addition, the importance of promoting start-ups and integrating digital processes in the healthcare sector was emphasised in order to increase both the attractiveness for specialists and the efficiency of medical care.

    The “Location Day” underlined the urgency of utilising domestic potential and continuously improving the framework conditions for a digital and sustainable transformation. The results of the workshops and panels will now be followed up in order to develop and implement concrete measures. Due to the high level of interest and productive contributions, a repeat of the event is planned in order to evaluate progress and new approaches in the coming year.

  • Wipkingen church becomes an educational space

    Wipkingen church becomes an educational space

    The Wipkingen church is a remarkable example of adaptive space utilisation. No longer used for church services since 2019, it is now intended to meet the space requirements of the neighbouring Waidhalde school complex. A concept developed by Vécsey Schmidt Architekten BSA SIA in collaboration with Anderegg Partner AG won the architectural competition and promises a cautious yet future-oriented transformation. A newly installed ceiling allows for the creation of a multi-purpose room, a library and catering facilities at ground floor level, while the upper floor offers flexible usage options under the historic church vault.

    André Odermatt, Head of Building Construction, emphasises the importance of this initiative: “The intelligent conversion of existing buildings is essential in order to meet current challenges in urban areas.” The project not only provides solutions to the urgent need for school space, but also strengthens cooperation between the city and the church.
    Thanks to this conversion, the necessary rooms for six to eight additional classes will be created by the 2031/32 school year. Filippo Leutenegger, Head of School, sees this as an example of the effective utilisation of creative solutions.

    The cooperation with the Reformed parish of Zurich has already borne fruit and plans to open up further church buildings for charitable purposes. The project in Wipkingen is just the beginning of a series of initiatives that prioritise community benefit.

    The estimated construction costs amount to CHF 7.5 million, with completion planned for 2026, in time for the start of school in 2026/27. This project marks an important step in Zurich’s evolutionary urban development by showing how historical substance can be meaningfully brought into the future.

  • Opening of the new innovation park near the Paul Scherrer Institute

    Opening of the new innovation park near the Paul Scherrer Institute

    The Innovaare park was opened on 25 April in the presence of Federal Councillor Guy Parmelin and State Governor Dieter Egli. According to a press release, the innovation park comprises 23,000 square metres of clean rooms, laboratories, precision workshops, offices and meeting rooms. “To date, we have attracted 21 companies, including a total of 15 spin-offs from the PSI, ETH or FHNW, two technology transfer centres and large international companies”, CEO Robert Rudolph is quoted as saying in the press release. “The overall occupancy rate is around 80 per cent and we are very confident that we will be able to increase this even further in the coming months.”

    The new innovation park is located in the immediate neighbourhood of the Paul Scherrer Institute (PSI). This is a strategic partner and the largest tenant in Park Innovaare. The Innovaare Park focuses on photonics, quantum technologies, life sciences, advanced manufacturing and semiconductor technologies as well as energy and sustainability.

    “New findings, methods and specialists from research are to be made accessible to the economy. This will further strengthen Switzerland’s high level of competitiveness”, Christian Rüegg, Director of the PSI, is quoted as saying in the press release.

    Park Innovare is Switzerland Innovation‘s sixth location. “Switzerland has been one of the most innovative countries in the world for years. In order for marketable products and services to emerge from our excellent education and research, our universities must be linked to the economy in the best possible way”, Andreas Rickenbacher, President of Switzerland Innovation, is quoted as saying. Park Innovaare is the best example of how cutting-edge research can be optimally linked with the economy.

  • Green cities as trailblazers for global climate impact

    Green cities as trailblazers for global climate impact

    The MCC study, published in the journal Nature Cities, highlights four key methods of CO2 removal in urban environments that could sequester one gigatonne of CO2 annually by the middle of the century. The methods analysed include adding biochar to cement, increasing the use of wood in construction, enriching urban soils with biochar and installing CO2 filters in commercial buildings. Together, these approaches could make a significant contribution to achieving net-zero urban emissions.

    Urban strategies for the climate and more
    Quirina Rodriguez Mendez, PhD student at the MCC and lead author of the study, emphasises that these techniques are of great benefit not only in terms of climate protection, but also for environmental quality and well-being in cities. For example, the use of special colour pigments and surface materials to improve the reflectivity of urban surfaces could significantly lower the temperature in cities and reduce the energy required for air conditioning systems.

    Local actions with a global impact
    The study emphasises the role of cities as “test laboratories” for climate protection, where local measures can be implemented quickly and potentially scaled up globally. Felix Creutzig, head of the MCC working group and co-author of the study, emphasises that local climate solutions, although often underestimated, can have an impressive impact and improve quality of life. The research findings offer important insights and recommendations for policymakers shaping urban infrastructure and policies.

  • WSL takes social factors into account when choosing a location for renewables

    WSL takes social factors into account when choosing a location for renewables

    Researchers from the Swiss Federal Institute for Forest, Snow and Landscape Research(WSL), the Swiss Federal Institute of Technology in Zurich(ETH) and the Vienna University of Technology have developed an innovative approach to selecting sites for renewable energy plants. According to a WSL press release, they are moving away from traditional methods that primarily take technical and economic factors into account. The new approach was developed by lead author Boris Salak (WSL/Vienna University of Technology) and his colleagues Felix Kienast and Marcel Hunziker (WSL) as well as Adrienne Grêt-Regamey, Ulrike Wissen Hayek and Reto Spielhofer (ETH).

    The study shows that different planning priorities entail different spatial, environmental and social costs, lead author Boris Salak is quoted as saying. “We have found that there is no one ‘right’ planning priority, but that this is a process of weighing up priorities. We see that optimisation according to social aspects is a good compromise between the other two priorities.” This optimisation brings the highest acceptance and is spatially as effective as optimisation according to energy efficiency.

    In a representative survey throughout Switzerland, participants were shown two scenarios. The pictures showed wind turbines, photovoltaic systems on roofs or in open spaces and high-voltage power lines. Respondents were asked to decide which image was most appealing to them or whether none of the energy scenarios shown appealed to them.

    According to the WSL, the population clearly favours the agricultural Central Plateau over near-natural landscapes for the development of energy landscapes.

  • Efficient utilisation of building heat – EMPA’s HEATWISE project

    Efficient utilisation of building heat – EMPA’s HEATWISE project

    At a time when sustainable energy management is becoming increasingly important, the unused waste heat from IT systems in buildings represents a considerable waste. Hospitals, universities and office complexes have extensive IT infrastructures that not only consume energy but also produce a significant amount of heat that remains largely unutilised. The Horizon Europe project HEATWISE addresses this challenge and brings together twelve research and industry partners from eight countries to develop innovative solutions for utilising this waste heat.

    The project, which was launched in early 2024 and will run for three years, is funded by the European Union under Horizon Europe and by the Swiss State Secretariat for Education, Research and Innovation. A key element of HEATWISE is the development of predictive control algorithms that not only link the IT infrastructure and building technology, but are also designed to enable energy-efficient, low-carbon and cost-effective operation.

    One example of the practical realisation of these goals is Empa’s “NEST” research building in Dübendorf, which serves as a real pilot plant. Here, the waste heat from a microcomputing centre is already being successfully used for heating, supported by innovative cooling technologies such as the “on-chip liquid cooling” system from Israeli project partner ZutaCore. This enables optimum heat recovery and the utilisation of the recovered heat for high-temperature-intensive applications, such as hot water supply.

    For specialists from the property and location development sector, HEATWISE not only offers insights into pioneering heat recovery and energy efficiency technologies, but also concrete application examples that show how IT infrastructures and building technology can be used synergistically for more sustainable energy management.
