Statement from customer
“Because of the unique concept of the active energy house we were able to realise our dream of ecologically and economically meaningful living and working under one roof. This includes the decentralised energy supply using an optimally designed photovoltaic system in combination with a purely monolithic design, which stores the pleasant radiated heat from HALLER Infrarot in an optimum way and provides extremely low consumption values and an extremely pleasant room climate. We also obtain most of the electricity for warm water from our photovoltaic system, and our E-Smart can also be recharged with the energy of the sun directly at home. And our guests feel perfectly comfortable in our seminar rooms!”
