    AEW builds heating network in Villmergen industrial estate

    AEW Energie AG has announced its intention to become more efficient in the expansion of renewable thermal energy and is establishing a heating network in the Villmerger industrial area at a cost of CHF 12 million. According to a press release, the municipality granted permission for the building application submitted in April. Construction work is to start in the 4th quarter of the current year. The date for the first delivery of renewable district heating to about 550 single-family homes is set for the 2024/2025 heating period.

    David Gautschi, Head of Production at AEW, has announced that the total heat will save 710,000 cubic metres of natural gas annually, which would cause 1500 tonnes of CO2 emissions.

    According to the information, the heat network uses waste wood as fuel, wood from the region as needed according to ecological cascade use, and solar energy with the help of a photovoltaic system with a peak output of 200 kilowatts.

    The supply unit is to be built between the Bünztalstrasse in the south-west, the municipal boundary in the south-east, the railway line in the north-east and the agricultural zone in the north-west. The heating centre will be built on the Cellpack AG site on Durisolstrasse. The fuels will be supplied via Anglikerstrasse and the Cellpack AG site.

    With this project, the Aargau electricity supplier wants to make a contribution to the Energy Strategy 2050.

    viboo saves heating energy with a learning algorithm

    viboo has developed an algorithm to save heating energy. According to a press release , the spin-off of the Federal Materials Testing and Research Institute ( Empa ) can also heat older buildings with around a quarter less energy. The user comfort remains the same or even improves.

    Researchers Felix Bünning and Benjamin Huber developed the idea while working in Empa's Urban Energy Systems Lab. Based on weather and building data, the control algorithm can calculate the ideal energy consumption of a building several hours in advance. The first experiments in NEST , Empa and Eawag 's research and innovation building in Dübendorf, reduced energy consumption by 23 percent. The researchers worked together with the thermostat manufacturer Danfoss . In comparison, the Danfoss Ally thermostat saved only twelve percent.

    In March 2022, the two researchers founded viboo together with Matthias Sulzer, Senior Researcher at Empa, to bring the solution to market. In the next heating season, the company will carry out further test projects, apart from with Danfoss also with other manufacturers such as ABB and Schneider Electric .
