Building the clean energy transition
Thanks to geothermal energy, solar panels, and thermal concrete activation, the campus operates almost entirely on renewable energy – making it a model for future educational infrastructure.
The construction of the school minimized carbon emissions by using Holcm's low-carbon cement, which today qualifies as part of our ECOPlanet range.
Harnessing thermal concrete activation
Using a geothermal heat pump, the school extracts heat from the ground in winter, which is then stored and released inside the building thanks to pipes introduced into concrete components such as ceilings and floor slabs. In summer, heat is returned to the ground. Since the electricity required for the heat pump comes from solar panels on the roof, the system is cost free.
Building sustainably
ECOPlanet is the world’s broadest range of low-carbon cement. We use calcined clay and recycled construction demolition materials in our mixes to reduce the CO2 footprint by up to 50%, and can go further leveraging alternative fuels.
Bildungscampus Seestadt was built using Holcim’s low-carbon cement, to make the school as sustainable as possible.
LEGACY
Building net zero
This school is a pioneering project that shows how thermal concrete activation can play a major role in helping cities like Vienna achieve their net-zero targets. Holcim’s sustainable building solutions are helping to ensure that children in Vienna and farther afield have access to inspirational and sustainable places of learning.
“This building is so special because 90% of its energy is generated onsite. Through geothermal technology, we extract heat from the earth. The concrete ceiling radiates the heat to the room. Conversely in summer, we can return heat into the ground. The electricity required for the heat pump comes from the roof. And there are no operating costs for the geothermal system. The concrete in this building is essential to be able to store and release the heat.”
