Multifunctional precast elements

The amount of energy generated from renewable sources is fluctuating and thus uncontrollable, which is why it must be stored in the building to ensure effective utilization. At the core of such building-integrated heat storage systems is usually a water tank. Buffer storage units need to provide a sufficiently large volume, i.e. normally several cubic meters, to increase the share of renewable sources in total heat consumption. However, a water tank is not the only option to store heat since the building’s load-bearing structure itself also provides this capability.
