Before we introduce you to this year’s winners, here are summaries of the five projects selected as runners-up.


Harvey W. Hottel, Inc., Gaithersburg, MD
Dodona Manor/The George C. Marshall International Center

Dodona Manor was the home of George C. Marshall from 1941 until his death in 1959. During this time, Marshall served as Army Chief of Staff, Secretary of State, and Secretary of Defense. The building, a national historic landmark, recently underwent a renovation to allow it to serve as a museum. The challenge for Harvey W. Hottel was to bring a building that was constructed in the late 1800s up to ASHRAE museum standards. The company designed and installed a system that has no visible outside equipment, low noise levels, is environmentally friendly, and handles an unusually high winter heating load due to the energy inefficient envelope.

Equipment list:

  • WaterFurnace geothermal heat pumps
  • Bryant gas furnaces
  • Bryant thermidistats
  • Bryant zoning system
  • Bryant variable speed blowers
  • Therma-Stor dehumidifier
  • EWC Controls humidifier

ACCO Engineered Systems, Inc., San Leandron, CA
State Compensation Insurance Fund, Oakland, CA

ACCO Engineered Systems was called in to address occupant comfort concerns in an owner-occupied, three-story, 54,000 sq.ft. office building. Built in 1982, the building’s HVAC system had undergone a number of modifications over the years, but still provided poor occupant comfort and low energy efficiency. After performing a thorough building analysis, ACCO implemented a solution that included replacement of the existing rooftop cooling tower and pumps with a new, 120-ton evaporative-cooled VAV unit with DDC controls. An additional 27-ton air-cooled VAV unit was provided to serve the building’s west exposure. Extensive structural and ductwork renovation was also performed. In true Design/Build fashion, ACCO served as the general contractor and managed every aspect of the project.

Equipment list:

  • Mammoth VAV rooftop unit
  • Carrier air-cooled VAV units
  • Rite hot water boiler
  • Taco in-line hot water pumps
  • Metalaire VAV boxes
  • Metalaire diffusers
  • Griswold temperature control valves
  • Automated Logic DDC Controls
