Assoc. Prof. Dr.-Ing. Fabian Ochs studied Energy Engineering with a focus on renewable energies at TU Berlin. After completing his doctorate at the University of Stuttgart, he went to the Unit of Energy Efficient Building at the University of Innsbruck in 2009. He researches and teaches in the areas of energy-efficient buildings, building physics, HVAC technology, thermodynamics and renewable energy as well as energy storage. The holistic modeling and optimization of buildings and districts with their energy system is accompanied by experimental work in the laboratory and by monitoring in demonstration projects. Applied research in national and international research and industry projects is complemented by international networking through numerous IEA research collaborations. He is a member of scientific committees at international conferences as well as a member of the Austrian Standards working group (Committee 175 and 235), the VDI working group 4640, the working group on seasonal thermal energy storage as well as the IBPSA and the scientific advisory board of renowave.at. He is contract professor at the Free University of Bolzano/University of Trento (Master Energy Engineering) since 2012.

Dr. Georgios Dermentzis is a senior researcher at University of Innsbruck from 2018. In June 2018, he finished the PhD studies at same university. Since October 2012, he is working at University of Innsbruck, participating in several European, international and national scientific projects. His main research focus is on heat pumps for energy efficient buildings such as Passive Houses. His expertise lies in dynamic building and system simulations, as well as in-situ monitoring and tool development. He has fulfilled his diploma studies in Electrical and Computer Engineering at the Democritus University of Thrace, Greece in 2008.

Mara Magni is a Postdoc at the University of Innsbruck in the unit of energy efficient buildings where she is involved in different national and international research projects in which the objective is to holistically optimise the building by considering all its components (e.g. HVAC, envelope, renewable energy, storage, etc.) through the use of dynamic simulations and, possibly, through monitoring. She graduated at the University of Bologna as energy engineer in 2016 and doctorate at the University of Innsbruck in 2022 collecting experience in the field of dynamic building simulation and laboratory testing of new heat pump prototypes.

Elisa Venturi studied Energy Engineering at the Bologna University, focusing on nearly zero energy buildings, building simulation and renewable sources of energy. She arrived in 2018 at the Unit of Energy Efficient Buildings of the Innsbruck University to write her Master Thesis. She worked in the same Unit for a year as scientific assistant. She is currently a PhD student at the Unit of Energy Efficient Buildings of the Innsbruck University focusing on nearly energy buildings, building simulation and monitoring data.

William Monteleone studied Energy Engineering at the University of Trento and is currently a PhD student at the unit for Energy Efficient Buildings. His research interests focus on the simulation and experimentally-assisted development and optimization of compact and silent small-scale heat pumps for space heating and domestic hot water production. He is involved in teaching activities within the courses of Architecture, Civil Engineering and Environmental Engineering on topics regarding building simulation, acoustics, moisture transport, thermodynamics and automatic controls.

Prof. Erwin Kittinger studied physics at the University of Innsbruck and received his PhD in experimental physics in 1965. Between 1965 and 1967, Kittinger worked as a research associate at the Department of Physics and Astronomy at Louisiana State University, Baton Rouge, USA. He then worked as a university assistant at the Institute for Experimental Physics at the University of Innsbruck from 1967 to 1983. Kittinger's work focused on the field of physical acoustics: he was concerned with ultrasound measurement techniques and their application to the investigation of glassy and crystalline solids. Another focus was on theoretical and experimental work on the nonlinear electroelastic properties of piezoelectric crystals. In 1978 Kittinger was awarded the title of university lecturer in experimental physics with special emphasis on physical acoustics, and in 1983 he was appointed associate university professor at the Institute of Experimental Physics.

Erwin Kittinger was a long-time member of the Faculty Board of the Faculty of Natural Sciences and held the office of chairman of the study commission for the physics field of study from 1984 to 1987. Over the years, his research in the field of physical acoustics also directed his interest to problems of building and room acoustics. Thus, in May 1987, Kittinger was appointed full professor of building physics at the Faculty of Civil Engineering and Architecture at the University of Innsbruck. From 1995 onwards, Kittinger was Dean of this Faculty until 1999, with the implementation of the UOG 93 at the Faculty being the main focus of his activities. From 1997 to 2003 he was a member of the Senate (UOG 93). Between 1999 and 2003, Kittinger chaired the Faculty Council of the Faculty of Construction.

After studying technical physics and many years of professional activity in the electrical industry, he was instrumental in establishing the Institute for Experimental Physics at the Vienna University of Technology. In 1970 he followed a call to the then Institute of Physics (later Building Physics, now AB Energy Efficient Building) at the Leopold-Franzens University of Innsbruck.

As a habilitated physicist, Prof. Brandstaetter built up the Institute and, as one of the founders, also the Faculty of Civil Engineering and Architecture with great commitment and know-how. One of the goals of his work was, among other things, as an advisor to Tyrolean Hydropower, to promote the transfer of knowledge and the close networking of science and industry. Above all, however, Prof. Brandstaetter was a versatile teaching and research personality. He additionally taught at the Medical Faculty and was also involved in the development of a blood pump as an auxiliary device for heart operations. His achievements in research and teaching were honored with the Cross of Honor for Science and Art and the Keschenitz Prize of the Austrian Academy of Sciences.
