Energiewerk Graz

In collaboration with Graz-based architect Rainer Wührer, we developed design and functionality solutions for the exterior and selected common areas of the new Energiewerk Graz. The aim is to unite technical infrastructure with a clear, forward-looking architectural language that reflects both the project’s ecological ambitions and its role within the urban context.

Energiewerk Graz (EWG) is a key project driving the ecological transition of district heating in the greater Graz area. It aims to reduce dependence on fossil fuels - especially natural gas - and to strengthen the local circular economy. By utilizing non-recyclable residual materials, the plant generates sustainable heat and electricity. In doing so, the EWG makes a significant contribution to climate protection, air quality, and regional energy security.

The project is part of a long-term decarbonization strategy pursued jointly by the city, the province, energy providers, and public institutions. In addition to its ecological benefits, EWG also generates economic and social momentum: new jobs, stable energy prices, and reduced truck traffic. Construction is scheduled to begin in 2027, with operations planned for 2029, alongside ongoing, transparent public communication.

The appearance of the new Energiewerk Graz is intended to embody the project's ecological ambitions. Our goal was to develop an architectural solution that combines functional requirements - particularly the use of solar energy - with a clear design approach. The integration of photovoltaic panels was envisioned not only to serve an energy-generating purpose, but also to become a central element of the building’s façade design.

As part of this architectural strategy, we developed a parametric pattern that creates a vibrant, almost organic surface through varying rotation angles of the panels. The result is a façade in constant visual motion, shaped by light and perspective, which gives the building its dynamic presence. It stands as a visible symbol of innovation, sustainability, and architectural quality.

The simple, monolithic form of the facility is deliberately interrupted by a striking opening - an architectural incision that serves both functional and atmospheric purposes. It accommodates staff areas and a visitor center, creating a connection between technology, environment, and the public.

Seminar rooms, offices, meeting and lounge areas – including a “climate gallery” with a botanical forum - are integrated into an open spatial layout. This configuration plays a key role in communicating the principles of sustainable energy production.
