Building between openBIM and new planning approaches
Digitalization, open data standards and energetic urban spaces were the focus of the autumn energy talk in Graz.

Building between openBIM and new planning approaches
In the main part of the event "Building tomorrow - about openBIM and new planning approaches", Robert Charuza from Ikea Austria presented insights into the company's digitalization strategy, including how it deals with existing buildings. The openBIM approach (Building Information Modeling; open, cross-software data standard) was already used in the house at Vienna's Westbahnhof.
Star architect Lars Krückeberg, co-founder of the Graft office in Berlin, designed a visionary look into the future of planning and energy - with a focus on networked systems, material cycles and the role of digital mobility.
Digitalization in existing buildings

Charuza showed how 3D scans, digital twins and open standards such as openBIM accelerate the capture, analysis and further development of buildings. The aim is data-based, sustainable real estate management – supported by company-wide guidelines. “If we intelligently connect physical and digital data sources, we create the basis for better decisions – not just in construction, but in planning, operation and subsequent use,” emphasized Charuza.
Architecture as an urban energy system
Krückeberg put forward the thesis that in the future we will have to think less in terms of individual buildings and more in urban energy systems - networked, circular and open to transformation. “The best way to predict the future is to shape it today,” says Krückeberg, referring to the interaction of technology, resource conservation and design.
Classification by the organizers

“Digitalization and AI have long been part of the planning reality - and bring new opportunities, but also new complexity,” explained the organizers Johannes Huber-Grabenwarter (Odörfer Haustechnik) and Robert Pichler (founding member energytalk). The Energytalk offers the framework to examine developments from different perspectives. The dates for 2026 should follow soon on the website and on social media.
