N2 - The new DAfStb guideline “Greenhouse gas-reduced load-supporting structures made of concrete, reinforced or prestressed concrete” – a milestone for climate protection. In view of the existing climate change, it is clear that the fastest possible reduction of greenhouse gas emissions (GHG emissions) is also evident in the construction industry. Climate-friendly solutions are becoming increasingly important. In order to enable a quantifiable comparison of the “climate friendliness” of different solutions, the Technical Committee “Sustainable Construction with Concrete (TA NBB)” of the German Committee for Structural Concrete (DAfStb) developed the guideline “Greenhouse gas-reduced load-supporting structures made of concrete, reinforced or prestressed concrete (GHG guideline)” within around two years. The GHG guideline introduces a quantifiable application rule for climate compatibility in addition to the limit states of load-bearing capacity and serviceability known in the construction industry. The regulations and verification formats developed in the guideline will make it possible in future to calculate the relevant GHG emissions during the construction and disposal of a concrete structure acc. to uniform standards and to categorize them in a classification system. By introducing this classification system, clients, architects and structural engineers are enabled to set targets for the greenhouse gas savings to be achieved in comparison to a reference building or building component. The GHG guideline is a central element in the DAfStb′s strategy to lead concrete construction into the future, even in times of major ecological and technical challenges. Diverse efforts on the part of the cement, concrete and steel industries as well as the construction industry, architects and structural engineers prove that practical and safe solutions are already available today to significantly reduce the GHG emissions of concrete construction. However, there is great uncertainty in the market as to how ecological and sustainable such solutions are. In addition to the DAfStb GHG guideline, the DAfStb has therefore developed a wide range of documents and tools that enable architects and structural engineers to plan “ecological aspects” with certainty [1, 2].
