City of Neckarsulm

Project

The Albert Schweitzer High School in Neckarsulm uses smart heating. The county seat in the Heilbronn district is aiming to achieve net-zero_{CO2 emissions} as early as 2035. This makes its climate goal significantly more ambitious than that of the state of Baden-Württemberg (climate neutrality by 2040), Germany (climate neutrality by 2045), and the EU (climate neutrality by 2050). According to an emergency program for climate protection and the energy transition, achieving this goal requires, among other things, a renovation initiative for state-owned buildings. To this end, Neckarsulm is relying on vilisto. With the help of vilisto’s digital heating management system, the city of Neckarsulm is improving its energy efficiency and reducing emissions and heating costs.

The Albert Schweitzer High School’s energy consumption has dropped by 19.9 percent thanks to the use of AI-powered vilisto technology. Nearly 300 smart thermostats, which automatically regulate room temperature, save approximately 179,000 kilowatt-hours of energy per year—energy that is already generated from climate-friendly biomass (wood). This results in 50.1 metric tons fewer_{CO2 emissions} and 22,629 euros less in heating costs per year. The energy-saving project was partially funded by the Federal Program for Efficient Buildings (BEG). The investment paid for itself in just over three years.
