Using sustainable high-tech building materials from Heidelberg Materials, the DREIHAUS project by real estate company KRAUSGRUPPE is currently under construction in Heidelberg. It will serve as a future reference for serial 3D printing of residential buildings.
Developed as part of a collaboration between PERI 3D Construction and Korte-Hoffmann Gebäudedruck, 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.
“We are committed to creating real solutions for decarbonising 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,” says Dr Dominik von Achten, CEO of Heidelberg Materials.
“DREIHAUS, built with CO₂-reduced, circular building materials from Heidelberg Materials, exemplifies the transformation underway in the German construction industry. 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 customised solutions that provide optimal support for the successful realisation of diverse construction projects,” adds Christoph Streicher, General Manager Heidelberg Materials Germany.
Heidelberg Materials is 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 400 kg. Through innovations such as evoZero and the ongoing expansion of the circular economy and digitalisation, Heidelberg Materials is reinforcing its pioneering role in transforming 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 realise buildings or concrete products using 3D printing, not only high-quality products, but also technical expertise. Compared to traditional construction methods, the 3D printing process enables significantly reduced material consumption through appropriate design planning, thereby further decreasing CO₂ emissions. The process also increases construction speed and productivity, and makes construction sites safer by reducing dust and noise emissions and minimising tool use.
