Piotr A. Domanski (Fed)

Piotr A. Domanski is a NIST Fellow in the HVAC&R Equipment Performance Group of the Energy and Environment Division of the Engineering Laboratory. He completed his doctoral dissertation in 1983 at NIST on the modeling of vapor compression heat pumps. He remained with NIST and expanded his heat pump model, HPSIM, to include zeotropic mixtures and led the development of CYCLE-11, CYCLE_D, and EVAP-COND simulation models. He is a co-holder of two patents on refrigerant expansion devices.

In addition to his extensive work on alternative refrigerants, Dr. Domanski's research focuses on the development of measurement science needed to improve the performance of air-conditioning and heating equipment for application in both current buildings and net-zero energy structures. His main interest is in advanced simulation models, evolutionary computation-based optimization methods, automated commissioning, and fault detection and diagnostics. 

Dr. Domanski is a member of ASHRAE and International Institute of Refrigeration (IIR). He served as a member of ASHRAE Standards Committee, ASHRAE Research Administration Committee, President of IIR Commission B1 on Thermodynamics and Transfer Processes, the Regional Editor for the Americas of the Int. Journal of Refrigeration (IJR), a member of the IJR Int. Advisory Board, and the President of the IIR Science and Technology Council. He chaired the 1997 ASHRAE/NIST Refrigerants Conference and co-chaired the 2009 3rd IIR Conference on Thermophysical Properties and Transfer Processes of Refrigerants, and the 2012 ASHRAE/NIST Refrigerants Conference.

Dr. Domanski received the Award of Excellence for a Technical Paper at the 2002 Int. Appliance Technical Conference, the 2013/2014 Best Paper Award from the IJR, and the 2014 Best Paper Award from the Int. Journal of HVAC&R Research. He is also a recipient of a Bronze Medal Awards (1992 and 2016), Silver Medal Awards (2005 and 2009), and Gold Medal Award (2017) from the U.S. Department of Commerce, the William P. Slichter Award (1995) from NIST, the IIR Science and Technology Medal (2003), the Diploma of Honor "Academician Emeritus" (2009) from the Int. Academy of Refrigeration, St. Petersburg, Russia, the Wilbur T. Pentzer Achievement and Leadership Award (2012) from the U.S. National Committee of the IIR, the 2007 ASHRAE Distinguished Service Award, the 2016 ASHRAE Exceptional Service Award, and the 2016 Award for Engineering Sciences from the Washington Academy of Sciences. Dr. Domanski is an ASHRAE Fellow (2008) and the IIR Honorary President of the Science and Technology Council (2019).
