Dr. Dave Yashar is the Deputy Chief of the Energy and Environment Division (EED) of the Engineering Laboratory (EL) at the National Institute of Standards and Technology (NIST). He joined NIST in 1998 after completing his Master's degree from the University of Illinois and concurrently pursued and completed his Ph.D. in Mechanical Engineering at the University of Maryland.
Dr. Yashar was a member of the HVAC&R Equipment Performance Group (formerly Thermal Machinery Group) for 15 years before moving to the Division office. There, his research focused on making HVAC&R equipment more efficient, intelligent, and reliable. One major area of his work centered on improving the efficiency of air-to-refrigerant heat exchangers through measurement, modeling, and developing and employing evolutionary algorithm optimization techniques to generate no-cost design improvements. He was also heavily involved in the development and maintenance of standards for domestic refrigerating appliances for the U.S. Department of Energy, the Association of Home Appliance Manufacturers (AHAM), the International Organization for Standardization (ISO), and the International Electrotechnical Commission (IEC). His efforts have resulted in over 40 publications and new refrigerator/freezer standards in the US and abroad which are more in tune with modern appliances.
Dr. Yashar is currently a member of ASHRAE's Research Administration Committee, which oversees research related to building systems, energy efficiency, indoor air quality, refrigeration, and sustainability. He served as the Secretary for the 3rd International Institute of Refrigeration (IIR) Conference on Thermophysical Properties and Transfer Processes of Refrigerants and is a recipient of the 2009 Department of Commerce Silver Medal for Scientific and Engineering Achievement.
