effiziente.st Energie- und Umweltconsulting e.U.

effiziente.st is an Austrian applied research and engineering practice based in Graz, Styria, with over 25 years of experience bringing innovative energy and building technologies from idea to field-proven prototype (TRL 6–7).

The organisation brings four tightly integrated competencies to EU LIFE projects. As an experienced engineer in renewable energy technologies and buildings, effiziente.st has hands-on expertise in BIPV, heat pumps, heat recovery units, and bio-based building components. In the domain of energy telematics, the team covers the full data chain — IoT sensing, model predictive control, and modelling and simulation of energy systems — enabling evidence-based optimisation of building and infrastructure performance. Instrumentation expertise includes the in-house development of PCB-based temperature probes, advanced field measurement techniques, and server-side data collection (PHP) combined with embedded computing (Python), ensuring robust, project-specific monitoring solutions. Finally, a track record in workshop facilitation and academic teaching makes effiziente.st well placed to lead dissemination, capacity building, and stakeholder engagement activities within a LIFE project consortium.
