    Accelleron gets electricity from the roof in Baden

    According to a press release, Accelleron Industries AG has inaugurated the city’s largest photovoltaic system at its headquarters in Baden in the presence of Mayor Markus Schneider. The system was put into operation in December. It is spread across four roofs of company buildings with 2533 modules and a capacity of 1 megawatt peak output and is expected to produce around 1 gigawatt hour per year. According to the company, this corresponds to the annual energy requirements of 400 households or 150 journeys around the world in an electric car. Accelleron now covers 10 per cent of its annual electricity requirements in Baden with green energy, the statement continues.

    “As a leading company in the turbocharger industry, Accelleron is committed to decarbonisation and is making a positive contribution to sustainability,” said Herbert Müller, President of Accelleron’s High Speed Division and Co-Managing Director of the subsidiary Turbo Systems Switzerland. With this project, Accelleron Switzerland is playing a pioneering role in the use of renewable energies, Müller continued. Markus Schneider was the guest of honour at the inauguration ceremony. “I would like to thank Accelleron as an important Baden-based company for this commitment to renewable energies. This is exactly the kind of project we need on the roofs of companies in Baden,” Schneider is quoted as saying.

    According to the company press release, it took less than eight months from the internal project approval to the commissioning of the plant in December 2023. Although the project is still in an early operating phase, important insights have already been gained, such as the effects of snow conditions on electricity production with solar installations, according to Accelleron.

  • Helbing models room air

    Helbing models room air

    The engineering and consulting company Helbling uses innovative technologies to design ventilation systems for interiors, among other things to increase the air quality at workplaces. Last but not least, the COVID19 pandemic has put the reliable quality of indoor air at the top of the agenda of companies and institutions. According to a specialist article by Helbling, ventilation systems are also becoming more important because more and more buildings are being built according to the energy-saving Minergie standard. Improved thermal insulation and less fresh air supply help to save energy. However, sources of foreign matter such as building materials in the interior also influence the air quality.

    The aim of well-designed ventilation systems is to eliminate gaseous substances such as odors as well as irritating substances and particles such as dust or viruses from the ambient air. This also includes carbon dioxide from human respiration and tiny liquid droplets, so-called aerosols. In the technical article, the authors Reto Wäger and Christian Seiler emphasize that the transport properties of aerosols are used for an efficient analysis. Since aerosols move with the expelled air, the concentration and distribution of carbon dioxide in the room can be measured and analyzed using sensors. If real measured values already flow into the planning phase, for example for workplaces or factories, “a certain air quality at the workplace can be achieved right from the start with targeted measures”, says the article.

    To do this, the company uses flow simulations, for example. They are created using suitable software tools such as Ansys or COMSOL. Typical movement scenarios are also taken into account during planning. In addition, according to Helbling, other innovative systems can be used to optimize the room air, such as UV photocatalysis or plasma cleaning.
