An increasing use of renewable energies, especially regarding heat supply of residential buildings, leads to an increased demand in heat storage technology to counterbalance daily and/or seasonal energy fluctuations (e.g. during solar thermal use). Therefore, heat storage technologies are needed that minimize any potential environmental impact, are robust and present economically efficient solutions in newly built as well as existing houses.

Within the IGLU project, modular components are developed and tested for environmentally safe shallow subsurface, intelligent long term heat storage systems.

The main task of the Department MET is to install and conduct the monitoring of a heat storage demonstration facility in order to evaluate its environmental impacts on surrounding soil and groundwater.
