Biography
Dr. Eckhard A. Groll
He is the Reilly Professor of Mechanical Engineering at Purdue University and serves as the William E. and Florence E. Perry Head of Mechanical Engineering since July 1, 2019. He is world-renowned for his expertise in the fundamental thermal sciences as applied to advanced energy conversion systems, their components and working fluids with particular emphasis on vapor compression systems and positive displacement compressors.
Since joining Purdue, he has been the principal investigator (PI) or Co-PI on more than 120 research grants and more than 40 educational grants with a total budget of approximately $14 million from six different governmental agencies and more than 30 different industrial sponsors. He has advised more than a 100 graduate students and more than 150 undergraduate project students, visiting scholars, and visiting research associates. He has authored or co-authored more than 370 archival journal articles and conference papers. He has been the co-author of 4 book chapters and the editor or co-editor of 7 conference proceedings. He serves as the Regional Editor for the Americas for the International Journal of Refrigeration.
Dr. Groll is a 2010-2011 Fellow of the American Council on Education (ACE) and a 2009-2010 Fellow of the Academic Leadership Program of the Committee on Institutional Collaboration (CIC-ALP). He has received numerous awards for his research and teaching excellence including most notably the 2018 J&E Hall International Gold Medal in Refrigeration by the Institute of Refrigeration (IOR) and the 2017 Peter Ritter von Rittinger International Heat Pump Award by the IEA Heat Pump Center. In addition, he was inducted into Purdue's Book of Great Teachers in 2008.

Dr. Davide Ziviani
He is a Research Assistant Professor at the Ray W. Herrick Laboratories working with Prof. Eckhard A. Groll and Prof. James E. Braun, and serves as the Associate Director of the Center for High Performance Buildings (CHPB). He has extensive expertise in the modeling and testing of thermal systems and their components, including positive displacement compressors and expanders, organic Rankine cycles for waste heat recovery, as well as advanced conventional and disruptive HVAC&R technologies for residential and commercial applications.
Dr. Ziviani received his Doctoral degree in Electromechanical Engineering from the University of Ghent in Belgium, and Master's and Bachelor's degrees in Mechanical Engineering from the University of Ferrara in Italy. He began his research on waste heat recovery at San Diego State University. He has authored and co-authored more than 80 archival journal articles and conference papers. He has also the co-author of 4 book chapters.
Dr. Ziviani is actively involved with ASHRAE and IIR. He serves as the Research Chair of ASHRAE TC 8.1 and as the Vice-Chair of ASHRAE TC 8.3. Moreover, he serves also as a member of the editorial committee of the Knowledge Center on Organic Rankine Cycle (KCORC) technology. He is part of the organizing committees of the Rankine 2020 Conference to celebrate the bi-centenary of the birth of William Rankine as well as of the 2020 Purdue Conferences at Purdue.

Abstract
Residential and commercial buildings in the U.S. account for approximately 40% of the nation's total energy demand and about 75% of all electricity use. As a consequence, building technologies have significant potential to reduce energy consumption, improve the environmental impact, and provide cost-effective grid services and energy storage opportunities, while maintaining occupant satisfaction and productivity.
Within this context, the Center for High Performance Buildings (CHPB) at the Ray W. Herrick Laboratories was established with the intent of partnering with industry to develop, demonstrate, and evaluate new technologies and analysis tools that can enable significant improvements in the performance of buildings. The optimization of building technologies requires multi-disciplinary research efforts to address numerous important issues including indoor environmental quality, human comfort, comfort delivery, building envelopes, lighting, equipment efficiency and reliability, environmental impact, controls, automation, renewable energies and energy storage.
This seminar will provide an overview of the CHPB research activities and the unique facilities and testbeds utilized to conduct research. In particular, current research efforts concerning high performance equipment (e.g., heat pump systems, compressors, and appliances), building system technology (e.g., comfort delivery, building envelopes, sensors), and indoor environment and human perception (e.g., indoor air quality, interfaces, personalized control) will be introduced. At the end of the seminar, future perspectives on resilient extraterrestrial habitats will be given.
