New reference project for serial 3D-printed residential construction
Premiere for serial 3D construction printing with sustainable building materials from Heidelberg Materials
USING sustainable high-tech building materials from Heidelberg Materials, the DREIHAUS project by real estate company KRAUSGRUPPE is currently under construction in Heidelberg and will serve as a future reference for serial 3D residential building printing.
Developed as part of a collaboration between PERI 3D Construction and Korte-Hoffmann Gebäudedruck, the scalable concept for a three- story apartment building has been optimized for 3D printing.
Leveraging their expertise in 3D concrete printing and the decarbonization of the built environment, Heidelberg Materials are providing high-tech materials with a substantially reduced carbon footprint for the implementation of DREIHAUS in Heidelberg.
The first two of three buildings planned in Heidelberg will be constructed using evoBuild 3D printing – a fully recyclable construction material. This material features a binder with a carbon footprint that is more than 50% lower than that of conventional Portland cement.
For the third building, the partners are taking a pioneering step: evoZero from Heidelberg Materials will be used as the binder, marking its first application in Germany. evoZero is the world’s first carbon captured cement, allowing customers to make significant progress toward their climate targets. The CO2 reduction in evoZero is achieved through the application of innovative carbon capture technology at the Heidelberg Materials plant in Brevik, Norway.
‘We are committed to creating real solutions for decarbonizing the built environment and advancing sustainable innovation together with our partners. With the German premiere of evoZero, the world’s first carbon captured cement, we are ringing in a new era of sustainable construction today in Heidelberg and across the country,’ said Dr Dominik von Achten, chief executive officer of Heidelberg Materials.
‘DREIHAUS, built with CO2-reduced, circular building materials from Heidelberg Materials, exemplifies the transformation under way in the German construction industry,’ added Christoph Streicher, general manager of Heidelberg Materials Germany. ‘Here, we are demonstrating how the continuous expansion of our sustainable product portfolio enables us to offer our customers not only highly innovative, but also customized solutions that provide optimal support for the successful realization of diverse construction projects,’
Heidelberg Materials are pursuing an ambitious sustainability strategy: By 2030, the company aims to generate more than 50% of its revenue from sustainable products and reduce specific net CO2 emissions per tonne of cementitious material to below 400kg. Through innovations such as evoZero and the ongoing expansion of circular economy and digitalization, Heidelberg Materials are reinforcing their pioneering role in the transformation of the building materials sector.
3D-printed products are an integral part of the portfolio. The company offers architects, engineers, manufacturers of 3D printers, and builders who want to realize buildings or concrete products using 3D printing not only high-quality products but also technical expertise. Compared with traditional construction methods, the 3D printing process enables significantly reduced material consumption through appropriate design planning, thereby further reducing CO2 emissions. The process also increases the speed and productivity of construction processes and makes construction sites safer by reducing dust and noise emissions and minimizing the use of tools.
