Roberto Del Real, MBA, P.E.Associate DirectorUtilities and Energy Management

Background

» 51,000 students, 24,000 faculty and staff and 17 million square feet

» 350-acres and 200-plus-buildings

» 65 MW peak load – 350 million Kwh

» 35,000 peak tons of CHW – 157 million ton-hours

Background

» 220,000 pph peak steam - 775 million pounds

» Deionized laboratory water

» Compressed air

» The University of Texas at Austin is world known for its good quality of education and research. In order to maintain this high standard of education, the uninterrupted, cost-effective, and efficient delivery of energy plays an important role.

» As a response to this, University of Texas at Austin – Utility and Energy Management Department decided to adopt a comprehensive and innovative solution for energy measurement and analysis which would help in achieving the goal of efficient energy supply for university campus.

» An innovative solution that is inclusive to all Campus Energy Systems was develop with the objective of presenting different sources of energy data to the user in an easy to use interface.

Real Time Energy Dasboard

INITIAL GOALS» Make metering and billing maintainable» Provide campus users “real time” and historical energy data» Make building energy data “readily accessible” for use by

energy conservation programs.

Real Time Energy Dashboard

ADDITIONAL CHALLENGES» Campus Building Energy Behavior Analysis» One-stop shopping for all Campus Energy-related

data needs» Campus Energy Sources Data Availability» State-of-the-Art Trending capabilities

Metering “Phase-In” History

Network Segmentation Solution

Remarks

» Installation simplified which reduced cost using pre-built PLC boxes

» Automated Billing System reduced errors and labor» Meter issues identified quickly using “real time”

data» Starting to create smart utility customers» Some have achieved 15% energy reductions by

“watching” energy use» About 88% to 90% of all CHW, Power and Steam

delivered to campus now metered

Remarks

» About 88% to 90% of all CHW, Power and Steam delivered to campus now metered

» Energy Analysis and Trending “key” in reducing energy consumption

» Power Generation, and Distribution Data readily available

» Energy Dashboard consolidates data sources
