W-328, was a comprehensive project to prioritize energy projects at Orlando International Airport which included the development of a Comprehensive Energy Management Plan, referred to the “Energy Roadmap”. The project scope included performing an ASHRAE Level 1 Energy Audit on Airside Terminals 1, 2, and 3 as a component to the second phase of the Energy Road Map. The audit process began with a cursory review of the mechanical, electrical, and architectural record drawings for each of the airside terminals.  GreenPath staff helped to evaluate the air terminal’s potential for energy savings and help to screen potential energy conservation measures (ECMs).  Along with the walk-through site assessment, our staff performed brief interviews with site operating personnel and reviewed terminals utility bills and other operating data, all geared toward the identification of glaring areas of energy waste or inefficiency.  In addition, GreenPath logged all utility data into the USEPA Portfolio Manager tool and performed Energy Utilization Index (EUI), Cost Index (CI), and benchmark analysis for each terminal.  We also, observed the functionality and capabilities of the BAS system that managed much of the HVAC infrastructure, we reviewed control systems set points, schedules, trends and sequences of operations and analyzed opportunities to save energy, analyzed energy bills and conducted a brief on-site survey of each airside terminal.
