Problem
Conventional wind turbine towers rely heavily on steel and concrete, resulting in high embodied carbon, complex logistics, and limited material sustainability. The industry also lacks certified, high‑capacity timber tower solutions that meet rigorous German and European structural standards.
Solution
HolzTurm delivers fully engineered timber tower systems for utility‑scale wind turbines, leveraging engineered wood products such as LVL and CLT. The company provides end‑to‑end design packages that include structural analysis, foundation engineering with precast concrete elements, and detailed assembly and crane‑logistics concepts. All designs are validated through type testing and certified to DIBt RiLi WEA and Eurocode requirements, ensuring compliance for turbines up to 6 MW and heights of 300 m. By integrating patented steel‑to‑wood adapters and modular connection details, HolzTurm enables rapid on‑site erection while maintaining structural integrity. The solution also extends to wooden blade development, offering aerodynamic optimization and certification under the same engineering framework. This approach reduces material carbon intensity, shortens construction cycles, and provides a certified pathway for renewable energy projects to adopt sustainable tower constructions.
Target Audience
Primary customers are wind turbine OEMs, wind farm developers, and EPC contractors seeking certified, low‑carbon tower solutions for on‑shore utility‑scale projects.
