3 Proven Solution that Saves Energy Holistic and pre-emptive approach to campus energy management. Proven savings of up to 23% of total energy bill. Based on prediction, intelligence and costing. Low capital cost with a rapid return on investment. Saves money through: Smarter central plant management Detection of abnormal building behavior Improved operational planning Enabling better maintenance decisions Providing detailed management insight 3

8 Extensible and based on proven platform Every campus has important differences and priorities so an open solution that can be modified by end-users is needed IncuityCEM is built on IncuityEMI, the award winning platform used in hundreds of demanding Industrial applications If you can use Excel you can customize your application in almost any manner 10

9 Example Rice University 11

10 The Campus 4.1 Million Square Feet 83 Buildings Cogeneration (7.5 MW) Electricity 16 Megawatts Steam 130K lbs/hour Chilled Water - 14,000 Tons $800M expansion New District Cooling Plant 8 new buildings (10 story wet lab)

11 The Key Questions Are the buildings behaving? If not, what are the cost implications What are the financial implications? On target with carbon footprint? Is utility purchasing meeting plan? How to Operate the plant? Run the co-generators? Which chillers? Boiler configuration? Power level? Export electricity? Day-ahead electrical purchasing?

12 The Variables Demand prediction Weather (Forecast data) Campus Events (Campus ERP) Student Calendar (Facilities DB) Cost prediction Real time electrical market (Utility) Campus electrical contract (Financial) Natural gas price (Utility) Capability Prediction Control Systems Maintenance System Buildings Building automation Metering systems

13 Example Real time effective costs Spike in Market Clearing Price of electricity Actual cost of steam More than 70 factors affect cost 15

14 Example A managed building 16

15 Accurate Future Demand Reports 17

16 A typical building operating ABOVE expectations 18

17 Poorly behaving (Systems placed in By-Pass) 19

18 The Outcome Saving $3.5M/year in energy costs Identified control system malfunctions Improved sequencing and scheduling Optimized plant line-ups Negotiated better utility procurement More efficient maintenance
