Efficiency alone does not save energy Excerpt from a recent article in the Wall Street Journal RE: California Utility’s efficiency goals: “For the 2006-2008 program, utilities said they achieved energy savings from all their energy efficiency programs that were 151% of the goal set by regulators. But the commission's staff, armed with exhaustive studies, said utilities saved only 62% of the goal amount, hurt by the bulbs.” Active Energy Management requires both…smart technology and smart operators.
Why We’re Here Market Adoption of Energy Benchmarks Foreign Energy Dependency Financial Incentives and Rebate Programs Public Perception and Awareness Rising Energy Costs CO2 Reduction Mandates Climate Change Smart Grid Technology Job Creation — “Green Jobs”
Do we know how are we doing? Only 121 out of 552 LEED buildings know how they are performing.
78%
DON’T know how they are performing.

Does Green = Energy Efficient? “Green” Buildings don’t always perform as expected.

Challenges to Building Efficiency Why do well-designed, well-built facilities fail to meet performance expectations? Design/Construction Challenges Opportunity for better Transition to Stable Operations Opportunity for better coordination between construction trades Lack of quality assurance in building system performance
Operational Challenges
Increasing pressure to reduce budgets through staff reductions Lack of understanding of technology and performance measurement Poor maintenance practices Failure to incorporate facility best practices that leverage systems and data to measure performance and drive performance improvements
Meeting the Challenge Head-on Develop approach for measuring success Benchmark facility performance Define key performance indicators
Track Progress Monitor progress and status Implement performance alarms
Involve staff and occupants in efforts Promote involvement and awareness Communicate progress and results
Advanced Energy Monitoring Solutions
Performance monitoring software, data acquisition hardware and communication systems used to store, analyze and display building energy data.
Provides hourly whole-building energy data that are webaccessible, with analytical and graphical capabilities.

Analyze - What is a Benchmark?
Benchmarking is the process of comparing one's business processes and performance metrics to industry bests and/or best practices from other industries. Dimensions typically measured are quality, time, and cost. Improvements from learning mean doing things better, faster, and cheaper.
Analyze - Why Benchmark Performance? Establishes metrics for measuring ongoing performance Validates design intent and expected performance Identifies maintenance and operations opportunities Identifies equipment and control problems Aides in prioritization of energy investments and efforts Educates staff and occupants
Analyze - Metrics for Benchmarking Metrics for measuring ongoing and comparative performance Energy Based Metrics Use per square foot (EUI) EUI for each utility (gas, electric, steam, etc.) Demand per square foot
Cost Based Metrics Cost per square foot (ECI) Cost per occupant
Other Metrics Non-energy based utilities After hours use Green House Gas/Sustainability
Analyze - Benchmarking Performance Considerations for establishing benchmarks Data Normalization
Weather Square footage Facility type Plug loads (i.e. computers)
Who to compare too? Facility specific Historical comparison (baseline) Model comparison
Portfolio, region, national
Analyze - Example of Metering Software
Energy Management Software validates bill information and identifies anomalies
Analyze - Example of Metering Software
Energy Management Software provides reporting of bill performance compared to historical, forecasted, budget goals
Analyze - Example of Metering Software
Using Energy Management Software , meter data can be analyzed for identifying anomalies real time including afterhours use, abnormal peak demand, weekend use, and other performance metrics
Analyze: Example of Metering Software
When excessive use does occur, Energy Management Software provides detailed reporting of the incident including when, magnitude of the use, and the total impact that resulted
Act - Optimized Process Performance alarms processed and sent to Maintenance Management Systems to includes location, detailed description of issue, and procedures followed
Analytical tools are used to identify performance issues – the system provides immediate indication to Maintenance Management Systems of high demand and consumption patterns
Act – Persisting Energy Savings Savings Range 20%
On-going without Energy Management
The typical facility will become 3-5% less efficient every year.
Cost On-going Energy Management Program
Persistence is key to ongoing benefits Cost

Case Study: Pacific NW Smart Grid Solution
Validate new smart grid technologies and business models Provide two-way communication between distributed generation, storage, and demand assets and the existing grid infrastructure Quantify smart grid costs and benefits Advance standards for “interoperability” (the smooth, seamless integration of all elements of the electric system) and cyber security approaches.
The proposed project, led by Battelle, will: • Run 5 years and span 5 Pacific Northwest states: Idaho, Montana, Oregon, Washington and Wyoming • Involve 12 utilities in the five-state region, the Bonneville Power Administration, and multiple technology partners • Include direct participation from 2 universities—the University of Washington and Washington State University — with outreach to other academic centers • Involve more than 60,000 metered customers and will engage, using smart grid technologies, system electricity assets exceeding 112 megawatts • Cost approximately $178 million, half of which will be cost-shared by the project partners.
