Buildings become energy hubs


Bern – The Conference of Cantonal Energy Directors (EnDK) is presenting cantonal building policies on a new Internet platform. The goal is to turn buildings into energy hubs. According to a study commissioned by the EnDK, the specifications for the replacement of heating systems are having an effect.

Buildings should contribute to the implementation of the federal government’s Energy Strategy 2025. The cantons support this through regulations and the promotion of climate-friendly technologies. The goal is to turn buildings into energy hubs, EnDK explains in a statement. To illustrate this development, the EnDK has launched the new energiehub-gebä platform. Here, the legal basis and the status of the implementation of the cantonal building policy are presented and practical examples are given.

The Conference of Energy Experts of the Cantons also had the effects of the cantonal requirements for heating system replacement analyzed on the basis of five selected cantons. EBP Schweiz AG has been entrusted with the preparation of a corresponding study, the EnDK informs in a statement on energiehub-gebä The results showed that CO2 emissions from buildings have steadily decreased since 1990. The requirements defined in the model regulations of the cantons in the energy sector 2014 in the area of heating replacement were the decisive factor. There, a share of between 10 and 100 percent renewable energies is prescribed for residential buildings when replacing heating systems.

“On average across the five cantons, the regulations resulted in 90 percent of new heating systems in residential buildings being powered by renewable energy or waste heat,” the release said. The availability of gas and dense development in the urban environment are cited as complicating factors. Moreover, despite strong subsidies, financial reasons continue to play a role in the retention of fossil-fuel heating systems. ce/hs
