Against the background of global warming and the associated need to drasticallyreduce energy and resource consumption, action must also be taken in the buildingsector. Resource-efficient construction methods must be used that neverthelessallow the increasing construction tasks in areas such as infrastructure and housing tocontinue to be fulfilled. In order to successfully introduce a new construction methodto the market, the aspects of recyclability and economic efficiency are essential, inaddition to important government requirements for climate neutrality and technicalperformance. Above all, the economic viability, that is, the economic advantageous-ness, as well as its simple applicability compared to competing systems, decides onthe success and widespread use of a new technology. Carbon reinforced concrete,with its outstanding technical properties and simultaneous material efficiency, is animportant building block toward climate neutrality in the construction industry. It is apromising technology that still has to prove its economic advantages and robustapplicability under market conditions. In addition to the infrastructure sector, there isgreat potential in the area of housing creation, which needs to be tapped for carbonreinforced concrete. For this challenge, it is necessary to design a competitive valuechain that allows the realization of marketable products in mass production on exis-ting plant technology. The article gives a short overview of the economic and ecolog-ical status quo in the field of prefabricated construction with carbon concrete, usingthe example of the C3-result building CUBE. In particular, the CUBE-BOX, which ismade of prefabricated and semi-prefabricated parts, is examined in more detail andthe carbon reinforced concrete components used are compared with classicreinforced concrete constructions in terms of sustainability. In this context, the con-ceivable global climate protection contribution of the carbon reinforced concreteconstruction method is forecast based on potential market segments.
