Our story

The story of Larix Engineering begins in the autumn of 2011, with the founding of the Vienna branch of Cologne-based engineering office, IPJ Ingenieurbüro P. Jung GmbH.

The company has grown steadily and sustainably from four employees to around 20. Since 2013, it has also formed a synergetic office partnership with the IBR&I Institute of Building Research & Innovation ZT-GmbH.

The personnel growth in 2015 prompted a move to the current location at Tiefer Graben 21 in the first district, where Larix Engineering and IBR&I remain based today. In 2023, the office space was significantly expanded and attractively redeveloped at the same location. 

Our growth has been paralleled by the expansion of our service offerings. We have broadened our original core expertise in dynamic thermal building simulation into a comprehensive suite of planning and consulting services across four key areas: simulation, building physics, energy planning, and certification.

The renaming of IPJ Ingenieurbüro P. Jung GmbH to Larix Engineering GmbH took place in 2023, coinciding with the departure of the former German co-partner.  

Today, Larix Engineering is solely owned by its three managing directors:  
Peter Holzer as the company’s founder (2011),  
Matthias Kendlbacher, who has been with the company from the very beginning (also since 2011) and  
David Stuckey, who joined the company in 2018.
