Mr. Chvala (pronounced Koala, like the bear) came to Pacific Northwest National Laboratory in 1991 to work on energy performance evaluations of office equipment, building HVAC equipment, and lighting. Since then, he has been involved in numerous metering, data collection, demand-side management (DSM), and load-shedding projects. Previously, he worked briefly for a public electric utility and rural electric cooperative. He has been a Research Engineer in the Building Sciences and the Thermal and Electrical Systems technical groups at PNNL. Mr. Chvala's specialties include field data collection, utility data and rate analysis, and energy performance evaluations for Federal facilities and large military installations. He is also active in PNNL's long-standing program with the U.S. Army, helping them understand energy consumption on an installation level and identifying potential energy projects, fuel switching opportunities, load-shedding, and other operations improvements. More recently served as team lead for a partnership with the Army Reserve Installation Management Directorate, managing a large PNNL team providing analysis, planning, and direct project support for energy efficiency, renewable energy, and sustainability efforts.
