Reference project

Sustainable School Nuremberg

With the construction of the new Viatis School, the city of Nuremberg is focusing on sustainability right from the start: A passive house standard, photovoltaic system, battery storage and heat pump ensure a reliable energy supply. Around 400 pupils benefit daily from climate-friendly electricity and a modern learning environment.

Viatis School

  • Company: city of nuremberg
  • Location: Nuremberg, Bavaria
  • Industry: Public sector / Educational institutions

Benefits for Viatis School

Green energy in everyday education
Solar power is stored and used flexibly
Cost-conscious operation
Lower mains power requirements reduce ongoing energy costs
Role model for students
Sustainability is conveyed in a visible and tangible way in everyday life.
CO₂ reduction immediately measurable
Lower emissions through the use of requalified electric car batteries

Implemented use case

The school was planned according to the passive house standard and equipped with modern building technology. A PV system supplies renewable electricity, which is stored in the battery storage system and intelligently controlled. This ensures that the classrooms, lunchtime supervision and after-school care are supplied with electricity at all times – without having to rely on expensive grid extensions.

Self-consumption optimization
Independent and sustainable

Aim of the project

The city of Nuremberg wanted to create a new school building that was economical, climate-friendly and educationally pioneering. In addition to CO₂ reduction, the focus was on a secure supply for the 3100 m² school area and the role model function for sustainable construction.

Our customized solution

A 90 kWh battery storage system with 50 kW output was installed, combined with a heat pump and smart energy management. The system ensures that the PV electricity generated is used optimally, increasing self-consumption and efficiency and making the school a showcase project for climate-friendly energy supply in the education sector.
