President, Chief Executive Officer
Neil Petchers has been the President and Chief Executive Officer of NORESCO since 2005. Under his leadership, NORESCO has implemented major energy efficiency, renewable energy, and infrastructure upgrade projects for government and private industry clients throughout the U.S. and as far away as Guam, Alaska, and Japan. His projects have spanned more than 100 different modern energy efficiency and renewable energy technology applications, from high-efficiency chillers, boilers, HVAC and a range of conventional technologies, to innovative daylighting, cogeneration, fuel cells, wind turbines, and photovoltaics (PV).
Mr. Petchers previously held several management positions in the utility, consulting, engineering, and design-build contracting businesses. His utility industry experience includes development and management of both supply- and demand-side management programs, including conservation, environmental planning, cogeneration, and other alternative energy technologies.
With over 25 years of experience in the development and implementation of performance-based energy and resource cost reduction projects, Mr. Petchers has emerged as a recognized industry leader in energy efficiency and renewable technology. His book, "Combined Heating, Cooling & Power Handbook: Technologies & Applications; An Integrated Approach to Energy Resource Optimization" is used throughout the industry and as the basis for various courses, including The Association of Energy Engineers' Distributed Generation Certified Professional program. His first publication, "Cogeneration: Working One Fuel Twice" was published for the Cogeneration Coalition of America in 1983. He has also contributed multiple chapters to the "Encyclopedia of Energy Engineering and Technology," published in 2007.
Mr. Petchers' career has been punctuated by his involvement in various initiatives for public benefit. In the mid-1980s he began a project to apply state oil industry overcharge funds to upgrade the energy efficiency performance and living conditions of low-income apartments, creating benefits far greater than using the funds for one-time bill payments as they had traditionally been used. The State of Connecticut recognized this work with their Energy Innovation Award in 1987. Mr. Petchers also worked with Community Action Agencies and Boys and Girls Clubs of America, running programs to train and pay inner-city residents to work in neighborhood teams implementing building envelope upgrades and educating residents about energy savings practices. Mr. Petchers is also personally working on initiatives in remote African villages to improve cooking stove energy and environmental efficiency and to implement solar PV technology.
Mr. Petchers earned a BA at Brandeis University and holds a MS in Energy Management from New York Institute of Technology where he was also recognized with the School of Management's "Energy and Environment Award" for outstanding Academic Achievement in Graduate Studies in Energy Management.
