Campus Systems
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 entry
The Opportunity
• Event Management System– Dean Evans EMS®
• Low classroom use– Average of 17% campus-wide
• Opportunity to link to HVAC
The Solution
1• Update systems to direct digital control
2• Integrate Systems with Honeywell EBI®
3• Implement demand-limiting load shedding
4• Implement Events2HVAC™
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 protocol• Zone Control for individual rooms
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 Shedding
3. Demand-Limiting Load Shedding
• Predicts demand peaks• Sheds loads to control demand peaks• Lowers energy usage on high demand days• Lowers energy rates
4. Events2HVAC™
• Links event schedules to HVAC• Saves energy in unoccupied rooms• Eliminates redundant data entry• Adjusts dynamically to changing schedules
Events2HVAC™ How to Set it Up
• Know what / how your current HVAC system is set up
• Know what you want to control• Determine Building Hours & Building
Occupancy Hours• Add “HVAC” as a Building• Start Adding “Rooms” to drive operations
How Does it Change Scheduling?
• HVAC only runs on “Booked” status• Ballroom “event preset”• Creating “building occupancy” in addition to
setting building hours• Added reservations to maintain
Negative Side Effects
• Extra Reservations & Bookings to make• Scheduling of Rooms for deep cleaning • Load shedding is not always pleasant• 2 hour sync time frame• Hard to control humidity / heat in side rooms• Intricacies of certain buildings / spaces
Positive Side Effects
• Reduced GMW labor on campus for cleaning• Increase in room requests, decrease in “room
crashing”• Doors can be tied into the system• Easy to extend the HVAC run time
• $$$ SAVINGS!
