Conserve program; finding new ways to promote the sustainability message to a wider food service audience.
Donald R. Fisher, P.E.
President Fisher Consultants
Don Fisher, President of Fisher Consultants, is the former manager of the Food Service Technology Center in San Ramon, CA. This Center develops and applies standard test methods for
evaluating the performance of food service equipment.
Don received a B.Sc. in Mechanical Engineering in 1972 and a M.Sc. in Mechanical Engineering in 1974 from the University of Manitoba. Soon after graduation, he jumped into
the world of foodservice energy research on a program funded by Energy, Mines and Resources Canada. After ten years of promoting energy efficiency in Canadian restaurants,
Don migrated to California in 1986 with his partner Judy Nickel to operate what has become North America’s foremost center on energy performance in commercial foodservice
– namely the PG&E Food Service Technology Center. This program is funded by California utility customers and administered by the Pacific Gas and Electric Company under
the auspices of the California Public Utilities Commission.
Conducting hundreds of restaurant energy audits over his career, Don cultured a passion and expertise for kitchen ventilation. Don was founding chairperson of a technical
committee on kitchen ventilation for the ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) to develop guidelines and standards for
foodservice operations. He was the 2006 recipient of the American Council for an Energy-Efficient Economy [ACEEE] Champion of Energy Efficiency Award recognizing his
leadership, technical skills, innovation, and persistence in changing national markets for energy-efficient food service technologies. He is a popular speaker at industry
forums and is the author of numerous industry research papers and articles.
Sr. Energy Analyst
Mr. Bell is responsible for the Food Service Technology Center’s (FSTC) energy audit/site survey program, which examines the cooking equipment, HVAC, lighting, refrigeration, water
heating and sanitation systems in commercial food service operations.
In a typical year he will conduct nearly 100 site surveys under the FSTC’s CPUC-funded Energy Efficiency for Commercial Food Service program.
Essentially the “man in the trenches”, Mr. Bell visits commercial food service sites ranging from the very small, such as coffee shops and delis,
to large full service kitchens like those found in hotels and public school cafeterias.
With his “real world” field experience and continuing research activities in the FSTC’s equipment testing laboratory, Mr. Bell brings a formidable
array of knowledge to the myriad of energy efficiency and sustainability workshops and seminars he conducts, all of which are designed to help
commercial food service operators reduce energy use and operating costs.
Amin Delagah is a project engineer at the PG&E Food Service Technology Center (FSTC), an unbiased research facility that focuses specifically on commercial foodservice applications.
Amin holds a B.S. in Mechanical Engineering and M.S. in Renewable Energy Engineering with a minor in Environmental Management. He has been at the center for seven years and currently
focuses most of his efforts on hot water systems research and technical outreach. Highlights of his research include the completion of a California Energy Commission Public Interest
Energy Research Report titled, “Energy Efficiency Potential of Gas-Fired Commercial Water Heating Equipment in Foodservice Facilities” and a Design Guide on “Energy Efficient Heating,
Delivery and Use”. Amin maintains a close working relationship with many water heater manufacturers and water heating experts and has been a leading advocate for the development and
promotion of condensing commercial water heaters.
He participates as an industry expert on the Consortium for Energy Efficiency Gas Committee Meeting on Commercial Water Heaters held monthly and provided input to Joanne O’Donnell in
the development of the report titled, “CEE High Efficiency Commercial Water Heater Initiative”. Amin has both organized and presented at two to three sessions annually for the last
three years at the ACEEE Hot Water Forum on hot water systems in commercial kitchens. He is the upcoming Handbook Chair of the ASHRAE Technical Committee 6.6 Service Water Heating.
Amin is actively working with California utilities to develop a high-efficiency water heater rebate program for food service facilities and continues to do laboratory and field research
on hot water systems.
