    Berner Kantonalbank focusses on climate-friendly mortgages

    Berner Kantonalbank wants to significantly reduce greenhouse gas emissions from its mortgage portfolio by 2030. To this end, BEKB is supporting energy-efficient refurbishments with the introduction of myky mortgages, BEKB announced in a press release. They are based on the renovation calculator of the myky online platform.

    “Our customers benefit from preferential conditions when renovating their homes in an environmentally friendly way”, BEKB CEO Armin Brun is quoted as saying in the press release. “At the same time, we as a bank are promoting the reduction of CO2 emissions in our market area.” By 2030, emissions from financed residential properties are to be reduced by 45 per cent and those from other properties by 35 per cent.

    The myky platform was launched at the end of 2021 by BEKB together with Energie Wasser Bern and Gebäudeversicherung Bern. The start-up specialises in practical tips and tools to support homeowners. In addition to BEKB, 16 other cantonal banks are currently involved, represented by NNH Holding AG.

  • Kerzers inaugurates district heating

    Kerzers inaugurates district heating

    Groupe E inaugurated its new district heating plant in Kerzers with open days on 15 and 16 November. According to a press release, the plant will have a capacity of 31 megawatts when completed and can therefore generate 61,000 megawatt hours of heat per year. The heat will be supplied to over 90 households, vegetable growers, the Papiliorama and public buildings.

    The plant will be heated to 90 per cent with wood chips from the region. This will save around 9000 tonnes of CO2.

    It is the third-largest district heating plant of the Fribourg energy supplier after the one in Fribourg and in the Entre-deux-Lacs region.

  • Circular economy in the construction industry

    Circular economy in the construction industry

    Decarbonising industrial processes is a key approach to reducing CO₂ emissions. An industry roadmap presented here serves as a guide for companies to identify and implement suitable measures.

    Optimisation of concrete as a building material
    The sustainable use of concrete requires optimisation of its properties and targeted use in line with its performance. At the end of a building’s service life, options such as renovation, refurbishment, demolition with reuse of components or recycling must be carefully considered.

    Pollutant management in the circular economy
    Effective pollutant management is essential for a sustainable circular economy. This includes both the client’s disposal concept during dismantling planning and the separation of materials and pollutants during material treatment.

    Dealing with PFAS
    Per- and polyfluorinated alkyl compounds (PFAS) are a particular challenge due to their longevity and ubiquity. The event shed light on the possibilities and limitations of dealing with this group of substances.

    Innovative decarbonisation projects
    One highlight was the presentation of the world’s largest electric melting furnace for rock wool. This project shows how decarbonisation is implemented in practice and the potential that lies in the production of stone wool. The 2024 autumn event underlined the importance of a sustainable circular economy and offered practical solutions for the construction industry.

  • District heating and sustainability for the Metro Shop

    District heating and sustainability for the Metro Shop

    According to a press release, the Metro Shop in Baden has been connected to the district heating and cooling network. With its high energy requirements and annual consumption of around 300,000 kilowatt hours, it is one of the largest consumers of Baden’s energy network. The connection will make it possible to reduce CO2 emissions by 50 tons per year, according to the city’s press release.

    The city of Baden is pursuing the goal of reducing its energy-related greenhouse gas emissions to net zero by 2050 at the latest. To this end, a consistent switch to renewable energies is planned. In cooperation with Regionalwerke AG Baden, the city is driving forward the rapid expansion of renewable district heating and cooling, the report continues. The expansion is progressing rapidly. Five properties in the administrative assets with an annual consumption of around 1,235,000 kilowatt hours and five properties in the financial assets with an annual consumption of around 320,000 kilowatt hours (kWh) are already connected.

    Sandro Valsecchi, project manager for heating systems at Regionalwerke AG Baden, is quoted as saying that the many interfaces were one of the biggest challenges in the Metro Shop project. “Laying the pipes on both floors of the train station parking garage was particularly challenging – and that during ongoing operations,” says Valsecchi.

    The connection of the Metro Shop marks the completion of a key sub-project in the expansion of the district heating and cooling network. In future, the project will reach further areas of the city in cooperation with Regionalwerke AG Baden.
