Bauhaus Energy hub

Weimar | Germany

The Bauhaus Energy Hub combines experimental timber modular construction, energy-efficient building envelopes, and innovative material concepts into a forward-looking research and teaching project at Bauhaus-Universität Weimar. In the homogeneous timber construction system, LIGNOLOC® wooden nails by BECK were used as a metal-free fastening solution.

The Bauhaus Energy Hub was developed at Bauhaus-Universität Weimar as an experimental research and teaching building. The project focuses on resource-efficient construction methods, energy-efficient building envelopes, and new approaches to sustainable and circular timber construction. The modular room units are based on a consistently metal-free timber construction system. To connect the timber elements, the LIGNOLOC® wooden nail system by BECK was used, enabling a fully metal-free and material-homogeneous construction method while reducing CO2 emissions by 66% compared to conventional metal nails. By using LIGNOLOC®, the project was able to consistently implement its sustainable material concept, with a strong focus on circularity, prefabrication, and energy-efficient construction.

BECK X Bauhaus University Weimar

The collaboration focused on structural requirements for circular timber construction systems, energy-efficient building envelopes, and the integration of metal-free fastening technologies into prefabricated timber building elements. Students and researchers investigated the use of LIGNOLOC® wooden nails made from highly densified beech wood within material-homogeneous timber structures. This fastening technology enables high-strength fixing without metallic fasteners, thereby supporting monomaterial constructions and timber building systems designed for disassembly and pure-grade recycling (European Technical Assessments ETA-23/0330 and ETA-23/0041).

Metal-Free Timber Modular Construction with Wooden Nails by BECK

The Bauhaus Energy Hub is based on modular timber room units developed with a focus on energy performance, structural design, and material engineering. The aim of the research building was to create a resource-efficient and energy-efficient building structure with a high degree of prefabrication. Metal-free wooden nails by BECK were used to connect the timber elements. The LIGNOLOC® wooden nail system supports a material-homogeneous timber construction method and is particularly suitable for sustainable and circular construction approaches. By eliminating metallic fasteners, thermal weak points are minimized while enabling clean material separation and recycling of the timber components, as documented in the technical manual for LIGNOLOC®.

The Project

An interdisciplinary timber construction project by Bauhaus-Universität Weimar: The Urban Energy Hub combines research, architecture, and innovative fastening technology within a compact space. Using LIGNOLOC® wooden nails from BECK, a pure timber construction was created – metal-free, designed for disassembly, and fit for the future.

With the Bauhaus Energy Hub, we actively supported the development of metal-free and demountable timber construction systems in the context of university research. Our LIGNOLOC® wooden nail system played a key role in enabling new approaches to timber modular construction and prefabrication from a structural perspective.
