A special award of merit has been presented to developer Callahan-Pentz Properties for four energy efficient buildings at Hacienda Business Park in Pleasanton.

The Trane Co., the world's largest supplier of commercial heating and air conditioning equipment, presented the award to Callahan-Pentz for "achievement of an exceptional building environment that is responsive to occupant comfort and function, and provides for high efficiency in energy management."

The award is the first given by The Trane Co. to a developer in California, and only the sixth such award given worldwide.

"All four of the buildings cited at Hacienda are designed around a ‘Tracer’ Computer system that automatically controls individual areas for heating, ventilation and air conditioning, as well as interfacing with security systems, interior and exterior lighting and other electrical demands," explained Jim Dudley, vice president of Trane's Building Automation Division.

"Engineers at Trane felt that Callahan-Pentz had taken extraordinary steps in meeting the challenge of energy management and this award acknowledges our admiration and support of their far-sighted approach in developing quality, energy efficient buildings," Dudley said.

The Trane Co.'s award of merit was accepted by Callahan-Pentz Managing Partner Joseph Callahan and Construction Manager Daniel Shore in a ceremony held at Hacienda Business Park on Monday, January 20.

The four buildings awarded special recognition include: Park Plaza, a two building, 88,549 square foot complex, currently under construction; Site 34C, a two building complex with 86,577 square feet and on which construction will begin in mid-February; Chabot Center, a fully occupied, three-story office building with 71,989 square feet; and Sunol Center, Building A, a two-story office building with 55,440 square feet.

Professional organizations have previously cited Hacienda for excellence in architecture, landscape architecture and community development.
