tubes made of CO 2
-reduced steel and is strongly committed to achieving challenging sustainability goals . These tubes will be manufactured exclusively for Uxello and ZNB Maastricht , to be used as parts of sprinkler systems for commercial properties across Europe .
A second landmark project is the construction of Germany ’ s first modular building using
CO 2
-reduced material , the Heisenberg Gymnasium , a high school building currently being realized by ALHO Systembau GmbH , in Dortmund .
The first 82-room modules for the new building , covering around 4,000 square meters and consisting of three full floors and a staggered floor , are in construction now ; the building is scheduled for completion throughout the course of 2024 . By using Nexigen ® CO 2
-reduced material of the PRIME category , a total of 662 kg of CO 2 equivalents per ton of steel are being saved during production in the school ’ s construction . This reduces the CO 2 equivalents in the construction of the modular building by 316 tons or around 30 % in absolute terms when compared to solid construction .
In order to further optimize the environmental footprint of modular steel construction , ALHO aims at switching to green steel as far as possible in the future , thereby further reducing the CO 2 footprint of buildings .
It is no coincidence that both milestone projects are construction-related , despite the fact that the first batches had been delivered to Siemens and Mercedes Benz , in 2022 .
Why the construction industry ? First off , both private and public construction projects across the EU are required
