Building one of Vienna’s most energy-efficient schools with low-carbon materials

The need to transition to renewable energy sources and rising costs for heating and cooling buildings means that the places where we live, learn and work must be designed to be as energy efficient as possible.

With low-carbon cement, Holcim contributed to sustainably building one of the most energy-efficient schools in Vienna, the Bildungscampus Seestadt. It covers 90% of its own energy needs thanks to a geothermal energy process that is optimized by concrete’s thermal activation properties.

  • Covers more than 90% of energy needs with renewables
  • Thermal concrete activation instrumental in storing energy
  • Holcim’s low-carbon cement reduced CO2 emissions by 32% during construction phase

Holcim provided low-carbon cement to ensure that the concrete used for thermal activation purposes was produced as sustainably as possible. Nowadays, cements with a lower carbon footprint are part of ECOPlanet, Holcim's range of low-carbon cement.
