Residential building MEI Maishofen

Inserted capillary tube mats in the fibre-reinforced concrete slab extract the heat generated by solar radiation from the envelope, which can either be fed directly into the building's energy cycle as needed or fed into the underground ice storage system for intermediate storage. The principle is simple: if the solar input can already be intercepted and diverted at the surface, no additional energy needs to be used for cooling. The almost self-sufficient energy system is supplemented by a solar system on the roof and the way the ice storage works.

The energy stored in the concrete components is transported out of the concrete into the house or into the intermediate storage (= ice storage) by means of capillary tube mats through which water flows. The ice storage in this form can achieve a phase shift for the need of energy of approx. 5 - 7 days. Together with the photovoltaic system on the roof (for operating the water circulation pumps for the water flow through the FibreC façade), the house is almost self-sufficient.
