The structural ability and resource efficiency of the Cobiax technology leads to an improved performance of concrete structures as the weight reduction also has a beneficial effect on the vertical load bearing elements and foundations. The global ecological footprint exceeds the world’s bio-capacity by 30%  About 50% of the global energy requirement is needed for buildings. With an assumed life-cycle of 50 years, about 60% of a building’s energy requirement is needed for conditioning and operation. 40% is consumed by the embedded materials. Concrete slabs have the highest weight and volume share of a building's structure. With the use of Cobiax, the environmentally relevant toxic pollutants related to concrete slabs such as CO 2 are reduced by 20%. This is a relevant contribution for reaching the climate protection goals set by governments worldwide. Related to an entire building, the reduction of the environmentally relevant toxic pollutants related to building materials is up to 10% if using Cobiax (for an assumed building life-cycle of 50 years). In the project development and design phase of buildings, “open-space” concepts can be realized more efficiently with the use of Cobiax. The holistic consideration of a building’s life-cycle allows to identify the economical and ecological sustainability resulting from the use of Cobiax. Criteria related to sustainability and environmental performance will influence the economic valuation of properties in the future. The „Cleantech“ approach finds an ideal application in Cobiax.

Vision • Project developers and designers consider the efficient Cobiax Technology as a relevant factor for the holistic optimisation of concrete structures . • The resulting economical and ecological sustainability positions Cobiax as a “Cleantech” technology which holistically increases the financial value of properties. • The 20% reduction of environmental-related toxic pollutants resulting by the use of Cobiax substantially contributes to the attainment of the climate protection goals. This is considered as a relevant factor by investors.
