    IWB launches nanocomposite for heating systems

    The Basel-based energy supplier IWB is launching the nano-network as a new solution for heating outside the district heating supply in the canton of Basel-Stadt. According to a press release, when heating systems are replaced in houses or terraced houses that are close together, the heating systems are connected to each other and equipped with a central control system. IWB presented the nano-network to interested owners from the Mausacker district in Reinach for the first time on Wednesday, 6 March.

    As a rule, each property owner takes care of their own heating system. According to the press release, the individual heating systems are often oversized for safety reasons. Installation and heating costs are higher than necessary. In a nano-network, the heating systems of two to eight properties are physically connected and supplemented by an intelligent control system. All types of heating systems can be connected together.

    The control system ensures that the systems that provide environmentally friendly heating are used first. All connected owners can obtain an overview of energy production, consumption and costs at any time via an Internet application. In a second step, old, fossil-fuelled heating systems can be decommissioned.

    In a pilot project, the merger of three properties resulted in financial savings of up to 15 per cent. In addition, the three properties, in which a heat pump, solar thermal systems and gas heating systems were installed, were able to heat 90 per cent renewably as a result of the merger.

  • Heating renovations boost Meier Tobler’s business

    Heating renovations boost Meier Tobler’s business

    Meier Tobler can look back on a good half-year, according to a media release. The Schwerzenbach-based company, which specialises in air-conditioning technology, increased its turnover by 7 per cent to 276.4 million Swiss francs compared to the previous year. Net profit rose by 38.7 per cent to around 16 million Swiss francs.

    The “essential basis” for the growth was reportedly the continuing momentum in heating renovations. At the same time, sales of heat pumps also increased in the double-digit percentage range. Business with air conditioning systems improved only slightly compared to the previous year. Here Meier Tobler benefited mainly from large projects such as the delivery of two absorption chillers with 3.4 megawatts each for the Shoppi Tivoli in Spreitenbach AG.

    Furthermore, Meier Tobler was able to put its new service centre in Oberbuchsiten SO into operation in the first half of the year. Among other things, automated high-bay and small parts warehouses or autonomous mobile robots are in use in the newly built centre. According to Meier Tobler, operations are being ramped up continuously.

  • Lucerne University of Applied Sciences and Arts locates fossil heating systems

    Lucerne University of Applied Sciences and Arts locates fossil heating systems

    Experts from the Thermal Energy Storage Competence Center at the Lucerne University of Applied Sciences and Arts(HSLU) want to promote the climate-friendly replacement of fossil-fuel heating systems. To this end, the team worked with geoimpact AG, based in Lüterkofen SO, to use machine learning to calculate models that locate fossil fuel heating systems.

    This is because around 80 percent of oil and gas heating systems are currently being replaced by new fossil-fuel heating systems, according to a media release from the HSLU. “A new heating system needs planning,” HSLU energy expert Esther Lindner is quoted as saying. “Of course, if the old one breaks in the winter, you don’t have time for that, and then you just quickly replace what you had before with the same system again.” To counteract this, the project aims to provide these households with timely information about alternatives and counseling services.

    First, a model was created for 1957 municipalities, then one for 158 districts, and finally another for all of Switzerland. At the community level, the model is reported to be the most accurate, with close to 80 percent accuracy. The artificial intelligence of these models was trained with publicly available data from the building and housing register.

    Now the model is being developed into a referral program for a Sweet Edge project supported by the Federal Office of Energy. This is intended to assist communities with energy planning. “Communities that want to use the model and develop it at the same time,” Lindner said, “are welcome.” The project will also be presented at this year’s Evening of Business of the Department of Engineering & Architecture. It will take place on October 20, 2022.

  • Cantons are phasing out fossil fuel heaters

    Cantons are phasing out fossil fuel heaters

    The Conference of Cantonal Energy Directors ( EnDK ) passed "a comprehensive paper on the principles of building policy 2050+" at its plenary meeting on August 26, the EnDK informs in a statement . Among other things, it stipulates that by 2030 at the latest, no more fossil fuel heating systems will be installed in Switzerland. This is the only way Switzerland can achieve its goal of emitting no net CO2 by 2050, writes the EnDK. The future cantonal energy laws must be based on this principle decided by the EnDK.

    In the new policy paper, value is also placed on electricity production on the building itself. Above all, photovoltaic systems are to be used on roofs and facades. "The building will become an energy hub that not only consumes energy for the usual applications, but also increasingly uses it for the rapidly increasing electromobility and produces and stores electricity itself," Mario Cavigelli (CVP) is quoted as saying in the statement. The Head of the Department for Infrastructure, Energy and Mobility of the Canton of Graubünden, who is leaving the Government Council at the end of the year, handed over his office as President of the EnDK to the Head of the Department of Finance and Energy of the Canton of Valais, Roberto Schmidt (CVP). .

    Canton-owned buildings should be operated exclusively with renewable energies as soon as possible. The cantons are also currently preparing for a possible supply crisis. Here, too, the cantons want to “set an example” and coordinate the development of their own energy-saving measures, writes the EnDK.
