2. Enrollment – 9400 Undergraduate and Graduate combined Square Footage - 2.2 million square feet BAS Points Monitored - currently 125,000 expected to double in the next five years Central Steam Plant Satellite chillers at each building, some district loops for chill water & currently expanding loop systems Department of Facilities Management Maintenance & Operations

3. Decision Making? Department of Facilities Management Maintenance & Operations

4. Master Utility Spreadsheet 37 different tabs. Electrical Usage (kwh), Electrical Demand (kW), Electrical Cost, Outside Lighting Cost, Steam Usage, Natural Gas Usage and Cost, Dumpster Cost, Building Information (Square Footage/Renovation), Budget per Utility, Street Addresses, Heating/Cooling Degree Days are all incorporated into the Master Utility Spreadsheet. Department of Facilities Management Maintenance & Operations

5. Department of Facilities Management Maintenance & Operations Currently has five years of utility data Has been essential in forecasting utilities Has streamlined billing to auxiliary enterprises Has not increased time required for data management due to the fact that data requires entry into spreadsheet somewhere Has proven to be an excellent tool when working with outside engineering firms (eg. ESCO’s, commissioning agents, electrical provider, etc.)

6. Department of Facilities Management Maintenance & Operations Energy Use Index spreadsheet allows analysis of how buildings are performing.

7. Energy Use Index (Energy Use Intensity) is a unit of measurement that describes a building’s energy use. This represents the total energy (electricity, natural gas and steam) consumed by a building relative to its size or square footage. The electrical usage (kWh) and steam usage (pounds) are converted to a common measure of BTU (British Thermal Unit) and combined. This measure of energy usage is then divided by the square footage to give you the usage per square foot. This Energy Use Index can be used to provide a benchmark to compare facilities and/or a building against itself when energy conservation methods are pursued. The Energy Information Administration (Department of Energy) provides some information for comparison benchmarking and national averages on EUI and kWh usages per square foot for colleges and universities.

8. Department of Facilities Management Maintenance & Operations Allows comparison with external organizations with different utility rate structures Allows comparative reports to be developed between similar facilities or groups of facilities Information from EUI’s is used to target facilities for inspection or retro-commissioning based on performance

9. Department of Facilities Management Maintenance & Operations Sub-Metering at Building Level Steam/Water/Electric/Chill Water

10. Department of Facilities Management Maintenance & Operations Digital Sub-Metering- Allows for trending of data based on defined parameters Consistency and reliability of data from meters is critical - do your homework (e.g.. installation requirements, turn down requirements, compatibility with building automation systems, cost to calibrate, need for calibration) Targeting of buildings or systems that are outliers

13. Department of Facilities Management Maintenance & Operations Lessons Learned Ensure decisions are data driven Verify estimates and forecasts for projects against “actual” data Don’t become “attached” to a project/idea Don’t overlook the importance of routine maintenance Capital renovations will have the most significant impact to energy conservation

14. Department of Facilities Management Maintenance & Operations Where are we going? Natural Gas Cogeneration? Remain focused on reducing electrical demand (magnetic bearing chillers, precinct chill water, vfd’s, Capital and Maintenance Reserve Renovations, improved controls strategies) Development on “Design Standards” for controls strategies and sequences of operations for systems management Increase Retro-commissioning efforts
