Projects
United States Department of Energy’s Mid-Atlantic Combined Heat and Power Technology Assistance Partnership (CHP TAP) – Mr. Sweetser is a Senior Advisor to the Mid-Atlantic Combined Heat and Power Technology Assistance Partnership and represents the Center in Virginia, Maryland and the District of Columbia. In this role, Mr. Sweetser currently is advising: Federal, State and local governments, the U.S Military and various private sector owners by providing technical assistance to help them consider CHP, waste heat to power, and/or district energy with CHP in their facilities and to help them through the development process from initial CHP screening to installation.
EXERGY provides supporting analyses of CHP market opportunities in diverse markets including industrial, federal, institutional, and commercial sectors.
EXERGY also provides information on the energy and non-energy benefits and applications of CHP to state and local policy makers, regulators, end users, trade associations, and others.
United States Department of Energy – EXERGY provides CHP Technical and strategic support for the U.S. DOE Advanced Manufacturing Office.
Lawrence Berkeley National Laboratory - EXERGY is the coordinator for the U.S. DOE Packaged CHP Systems eCatalog providing overall design and operational guidance and technical review of all CHP packagers and packaged systems in the eCatalog.
New York State Research and Development Authority – EXERGY assessed the performance of 20 NYSERDA CHP sites. EXERGY co-developed NYSERDA’s Combined Heat and Power System Catalog and currently provides CHP technical support services for NYSERDA’s Industrial Research Program.
National Oilheat Research Alliance Liquid Fuels Research – EXERGY project manages research in the following areas: advanced primary combustion controller development, condensing warm-air furnace development, condensing oil boiler development, ammonia/water absorption heat-pump development, and 2-stage oil burner development.
