General Dynamics Hayden Facility
The General Dynamics Hayden Facility is one of the first projects to be certified under the LEED for Existing Buildings: Operations & Maintenance Rating System. It was an ambitious undertaking for reasons of both size and age; the 850,667 SF Hayden Facility was originally constructed in the 1950s, and constitutes roughly half of the overall Scottsdale campus. This effort was in addition to successful certification in 2005 of the General Dynamics Roosevelt Facility, under the LEED-EB 1.0 pilot program. Green Ideas developed a new process to benchmark complicated industrial facilities for energy performance and the process is now included in the LEED-EB Reference Guide. A $210,000 investment in LEED-EB resulted in a savings 0f $322,000. Green Ideas implemented several sustainable strategies into the operations and maintenance practices for the facility that significantly reduced both energy and water consumption.
Sustainable Strategies
-
Building Automation System was installed to monitor and control key building systems
-
Project participated in a Regional Trip Reduction Program, substantially reducing conventional commuting trips
-
Zero CFC-based refrigerants in HVAC base building systems improve Indoor Environmental Quality and reduce o-zone depletion
-
Implemented a Sustainable Purchasing Program for electrical equipment, furniture and high-efficiency lighting
-
Indoor Air Quality management program, Sustainable Design Education and High-Performance Cleaning programs were implemented for improved occupant health and awareness
Project Results
