Since joining PNNL in 1993, David Winiarski's research has focused on commercial building energy use, building codes, and more recently standards activities. Since 2013, Mr. Winiarski has served as a lead investigator for PNNL's Appliance and Commercial Equipment Standards (ACES) program. David has supported development of energy use and economic analysis for energy conservation standards and test procedures on air conditioning, commercial refrigeration, space and water heating, and lighting equipment. Prior to this, David developed commercial building code change proposals, code evaluation tools, and energy analysis for ASHRAE 90.1 and the International Energy Conservation Code (IECC); worked on development of Federal building codes; directed technical determination of energy savings activities for DOE; and participated and directed state assessments of energy savings from commercial codes through simulation modeling. Mr. Winiarski has also directed and performed long-term metering and field evaluations of efficiency and operational performance of air conditioning and water heating technologies for the U.S. Navy and for the Federal Energy Management Program.
