12 Controls/ Energy Management Systems Expand existing systems at City Hall and Police Station Install new compatible system at Maintenance Facility and Fire Stations Interface new & existing equipment with building management system to allow remote monitoring and control Evaluate existing computer strategies for control & efficiency Recommission existing controls and train personnel Proactive approach reduces risk 12

13 Controls/ Energy Management Systems Apply basic energy management strategies to reduce consumption Add occupancy sensors to reduce ventilation in unoccupied areas while maintaining comfort levels Upgrade electric controls to digital control for efficiency Replace old electric control valves and damper actuators to address deferred maintenance Apply day/night strategies to reduce operating costs Optimize existing digital setpoints 13

14 Lighting Systems Replace outdated ballasts and old technology bulbs Replace old fixtures and/or lens Install new energy efficient LED lighting to improve energy savings and lighting levels while reducing bulb replacement costs Address emergency lighting at City Hall Install occupancy sensors where applicable Utilize day lighting / dimming controls Add metering and lighting control for exterior lights Utilize photocell controls for exterior lighting Update pedestrian lighting and parking lot lighting with new LED modules for improved efficiency 14

15 Library HVAC 101 Air Handling Units (AHU) provide conditioned outdoor air through ductwork to the building for occupant comfort and ventilation. Heat is provided from a hot water boiler plant to the heating coil in the AHU. Cooling is provided by a refrigeration unit located outdoors to the cooling coil in the AHU. The Library renovation included a new cooling unit and new ductwork. 15

16 Mechanical Systems Add insulation to uninsulated areas Replace outdated boilers at Library with high efficiency condensing units to reduce operating costs Replace infrared heaters at FS#1 and Maintenance Facility Rebalance air handling units 16
