The entire project is being developed with the aim of being 100% CO2-free and achieving the highest standards in the field of renewable energy and recycling. Every aspect, from construction to operation at full capacity, should be a reference point for similar structures. It is an "active structure" by generating more energy than it consumes. To achieve this goal, photovoltaic energy is used in combination with geothermal energy and the energy of the thermal spring drilling. The thermal spring of Postal is the first large, Co2-free structure in the entire regional area.
