Founder of Grumman|Butkus Associates

In the early 1970s, few were thinking about energy. Most people in business, government, healthcare, and education took it for granted that energy was a fixed cost of doing business, and that supplies were plentiful. Dave Grumman, however, recognized how technical advances and the rising demand and cost for energy would create opportunities for providing energy-conserving solutions based on sound engineering and economic strategies. In 1973, he founded Grumman|Butkus Associates (formerly Enercon, Ltd.) as a one-person energy consulting firm. Over time, the firm has expanded into a full-service MEP firm with a wide range of specialized services. Dave Grumman's vision of providing energy-conserving engineering solutions resulted in Grumman|Butkus Associates' rise to a leadership position in energy-efficiency consulting and sustainable design.

Mr. Grumman retired from full-time employment at GBA in 1996 and stepped down as Chairman of GBA's board of directors in May 2013, continuing as a part-time consultant and Advisory Board member. When active, he directed numerous energy studies and headed both new and retrofit design projects. His technical specialties were energy conservation, conceptual design, indoor air quality, chilled water distribution systems, thermal storage, and controls.

Before 1973, he worked 13 years for a large, nationally known, Chicago architectural/engineering firm, where he was director of a department of 50 mechanical engineers and officer-in-charge of technical activities, including in-house computer operations. Among projects of major responsibility were the 60-story First National Bank building in Chicago's Loop and new studio facilities for WTTW, Chicago's public television station.

During his active years at GBA, work done under Mr. Grumman's direction included energy studies, mechanical system designs and upgrades, VAV conversions, microprocessor-based direct digital control (DDC) systems, solar system analysis and design, chiller plant analysis and expansion (including distribution line extension), thermal storage, and design of retrofits to remedy indoor air quality problems. Significant clients served included The Newberry Library, Chicago; DuPage County Governmental Center, Wheaton, IL; Christ Hospital and Medical Center, Oak Lawn, IL; University of Chicago Hospitals; Northwestern University, Chicago and Evanston, IL; and Amoco Corporation, Chicago and Naperville, IL. He was also very active in ASHRAE (American Society of Heating, Refrigerating and Air Conditioning Engineers), chairing many ASHRAE committees in past years and more recently making significant contributions to the Handbook chapters on Energy Resources and Sustainability. An ASHRAE Fellow, he received the ASHRAE 50-year Distinguished Service Award in 2014.
