As energy usage cannot be managed unless it is measured, Facilities Services initiated a building utility sub-metering program with the goal of metering and recording all utility usage for every building on the University of Idaho campus. Well over 100 meters have been added or replace in the last several years, which completes Phase-1, and nearly completes Phase-2 of our Building Sub-metering program. When Phase-2 is complete, all major campus buildings will be fully sub-metered for energy usage. Phase-3 involves metering energy for minor buildings such as farm facilities and temporary buildings, and metering water usage for all major buildings. Metering Program Accomplishments
- Received $15 ,000 in matching funds from Idaho Department of Water Resources
- Expanded utility sub-metering on campus. Includes Electric, Steam Condensate, Chilled Water, Domestic Water, and Irrigation Water meters.
- Selected a standard meter for each utility type.
- Coordinated with Architectural and Engineering Services to update University of Idaho new construction standards to include detail specifications for metering all utilities.
- Established an O&M program to periodically recalibrate University utility meters.
- Developed Utility Database for all metered data, including University sub-meters and Avista account meters.
- Developed a campus map (CAD) showing location of all meters, with meter information cross-referenced by meter ID to utility database.
- Developed Reports from new Utility Database.
- Enerey use reports, provided to all Auxiliary Utility Customers.
Electronic Meter Reading
- Energy use reports for all University buildings used by facility management to analyze building utility use patterns for energy conservation efforts.
All major components for Phase-2 electronic reading of University sub-meters have been selected and purchased, and installation is under way. The University has partnered with Avista, who is providing over $75,000 in equipment, software and installation reimbursement, to enable the University to electronically read the building electric sub-meters at all University buildings. The major advantage of electronic over manual reading is that the meters are read much more frequently, (for our system on a 5 minute interval). This detailed data is available for savings analysis and building system troubleshooting. Phase-3 will add the capability for electronic reading of Univesity steam condensate and water sub-meters in all major buildings.
