By replacing the obsolete pneumatically-controlled Building Automation System (BAS) with Johnson Controls Metasys®-based direct digital controls and open source BACnet protocol technology, GSA can now leverage advanced data analytics to support and inform energy management strategies and provide building operators with better insight into HVAC system performance.
Johnson Controls also migrated 22 air handling units to the new BAS system and replaced more than 3,000 obsolete pneumatically-controlled variable air volume (VAV) boxes with new digitally-controlled VAV boxes that offer more precise airflow and temperature control.
