Mer Charging Park Spital am Semmering – charging infrastructure with a glued laminated timber canopy and photovoltaics

Timber canopies for passenger car and truck charging bays

Practical experience clearly shows a growing demand for integrated solutions that combine charging, energy generation and user comfort. These multifunctional charging hubs are increasingly and deliberately chosen by users. The Mer Charging Park Spital am Semmering addresses this demand by treating charging infrastructure not as a standalone technical element, but as a functional space that brings mobility, energy and use together in a meaningful way.

Timber structures as load-bearing systems for modern charging parks

For this site, HASSLACHER group realised a large-scale canopy structure in timber construction. Instead of a purely functional solution, a high-quality structure made of timber was created. As a renewable material, timber stores carbon over the long term and thus makes a measurable contribution to resource efficiency and decarbonisation. In this way, the timber structure adds an ecological dimension to charging infrastructure while fulfilling all technical requirements.

Glued laminated timber as the structural system for passenger car and truck charging bays

The project comprises an efficient cantilever system for twelve passenger car charging bays as well as a 420 m² canopy for truck charging bays.
HASSLACHER group’s scope of services included structural engineering, timber construction, photovoltaics and lighting, delivered as an integrated solution from a single source.
Structural engineering and CAD design was carried out by Holzbau HOFER GmbH, a HASSLACHER group company based in Nikolsdorf, East Tyrol, in cooperation with freiraum ZT gmbh and srr Consulting – ZT GmbH. In total, 75 m³ of glued laminated timber in visible quality were used, manufactured at the HASSLACHER group production site in Hermagor (HASSLACHER Holzbausysteme GmbH).

Construction of the glued laminated timber structure was completed in two phases. The cantilever canopy was erected in November 2025, followed by the canopy over the truck charging bays in April 2026. Thanks to the high level of prefabrication and an efficient structural concept, installation in each phase took only a few days and was carried out by Holzbau HOFER. A winter shutdown due to weather conditions separated the two construction phases.

Photovoltaic canopy with integrated lighting

The roof surfaces are equipped with integrated photovoltaic systems. Glass-glass modules with a total output of approximately 121 kWp were installed. The system is complemented by integrated lighting that fulfils both functional and design requirements. Timber structure, energy generation and technical systems are coherently integrated both structurally and visually.

Added value in one location

The Mer Charging Park Spital am Semmering demonstrates how passenger car and truck charging infrastructure can be combined at a single site and enhanced through multifunctional design. The result is a clear and technically precise structure that not only enables mobility but also gives it spatial definition and long-term usability. The glued laminated timber canopy with integrated photovoltaics brings together timber engineering expertise, renewable energy generation and user-oriented infrastructure in one location, while contributing to environmental and climate protection.
