    Ostermundigen installs smart thermostats in school

    The council of the municipality of Ostermundigen recently voted in favor of the installation of 237 smart thermostats from the cleantech start-up Cleveron , based in Stettlen. According to a media release , they are intended to convert the radiators in the Dennigkofen school and reduce their heating energy consumption by up to 30 percent. The investment costs amount to 40,000 Swiss francs.

    These costs should have amortized after two to three years through the optimized energy consumption. Should the measure reduce the current energy consumption for heating by at least 8 percent, the municipality of Ostermundigen will consider equipping other school complexes and administration buildings with new thermostats.

    “With the pilot operation in the Dennigkofen school, we are testing how we can reduce energy consumption in our community-owned properties in the future. At the same time, the procurement is a contribution to minimizing the risk of energy shortages in the coming winter,” Maya Weber Hadorn, municipal councilor in Ostermundigen, is quoted as saying in the media release.

    Cleveron heating thermostats measure the temperature and humidity in rooms. They also take into account the current weather data and the outside temperature. A self-learning algorithm is designed to ensure optimal temperature regulation. All data can be displayed and evaluated via an app, and the thermostats can be controlled via it. Last fall, the municipality installed 220 Cleveron sensors in school buildings to improve air quality.

    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 .
