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

HVAC As a Building

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!
