With expertise and experience, the engineers Defiébre-Stefan have demonstrated how the planning of sophisticated building technologies, modern architecture and energy-efficient construction can be perfectly combined in the construction of their new own company headquarters. As an energy-plus building, IBVtikon generates more energy than it consumes. The hybrid solar system generates electricity and heat at the same time, surplus heat is stored for months in the solar storage unit under the basement slab, and there is a battery storage unit and twelve charging points for electric cars for the electricity that is not consumed.
