Problem, Solution, Results6 7. The Problem Poor energy efficiency across campus Most systems operated 14-18 hours per day Energy consumption (2008): 163 kBTU/sq. ft. Restricted budget Redundant, time consuming data entry7 8. The Opportunity Event Management System Dean Evans EMS Low classroom use Average of 17% campus-wide Opportunity to link to HVAC, lighting,8 and door controls 9. The Solution Update systems to direct digital 1 control Integrate Systems with 2 Honeywell EBI Implement demand-limiting load 3 shedding Implement Events2HVAC 49 10. 1. Direct Digital Control Pneumatic Control Assumes AHU Control on/off No remote control of Zone Some night setback control air pressure Early DDC (30-40 years old) Major systems only Chillers, AHUs, Pumps, Boilers No communication between different manufacturers Modern DDC supports open protocol10 Zone Control for individual rooms 11. 2. Honeywell EBI Integrate various legacy and vendor systems to open protocols and data formats 3rd Parties can consume data for enterprise reporting 3rd parties can integrate systems for energy efficiency Events2HVAC Demand Limiting Load Shedding11 12. 3. Demand-Limiting LoadShedding Predicts demand peaks Sheds loads to control demand peaks Lowers energy usage on high demand days Lowers energy12 rates 13. 4.

Network Infrastructure HVAC and Access Control systems on existing network, a private VLAN with restricted ACL (Access Control List) Honeywell/EBI, JCI, and EMS servers in Data Center with 24/7 monitoring, UPS/Generator Backup Public Safety dispatchers on staff 24 hours a day, monitoring events related to the Access Control systems19 20. Network Communication Eliminate Honeywell XL+ Controllers (1970s) Replace with Honeywell XL5000 Controllers Central integration point (Honeywell EBI) Common open protocol (BACnet/IP) Events2HVAC interface for JCI P2000 (XML/RPC)20 XML/SOAP web services used for JCI 21.

Obstacles, Surprises and Custom Features30 31. Obstacles City synch signal lost during storm Turned feature on, broke something31 else 32. Surprises Custodial staff spends less time cleaning classrooms locked between classes People outside campus asking why rooms they have used for meetings are locked More campus activities properly monitored via the campus scheduling system32 Changing the campus culture to a 33. Custom Features Lockdown, locks doors and disables cards for both JCI & Honeywell Emergency Fan Shutdown, currently by skilled operator client software soon to be part of Fire Control Software usable by Public33 Safety Dispatcher 34.
