2 Discussion Topics An overview of metering and software solutions used for Active Energy Management, and a discussion on how organizations can utilize technology to achieve energy management goals. 1. Driving Factors 2. Defining Active Energy Management 3. Active Energy Management Programs 1. Plan 2. Analyze 3. Act 4. Case Studies

3 Efficiency alone does not save energy Excerpt from a recent article in the Wall Street Journal RE: California Utility s efficiency goals: For the 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.

4 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

5 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. 22% New Buildings Institute: Energy Performance of LEED for New Construction Buildings March 2008 Know how they are performing. LEED NC buildings with post occupancy usage data LEED NC buildings Certified through 2006

6 Does Green = Energy Efficient? Green Buildings don t always perform as expected. New Buildings Institute: Energy Performance of LEED for New Construction Buildings March 2008

7 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

8 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

9 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.

16 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.

17 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

18 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

19 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

20 Analyze - Example of Metering Software Energy Management Software validates bill information and identifies anomalies

21 Analyze - Example of Metering Software Energy Management Software provides reporting of bill performance compared to historical, forecasted, budget goals

22 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

23 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

24 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

25 Act Persisting Energy Savings Savings Range 20% On-going without Energy Management The typical facility will become 3-5% less efficient every year. Cost Persistence is key to ongoing benefits Cost On-going Energy Management Program

26 Act - Example of Program Fluctuation Conservation Work Starts On Campus Phase 2 Conservation Starts

27 Act - Advantages & Benefits of Program Performance Improvement Annual predicted energy savings (% reduction in energy use) CO2 emissions reduction Education and Outreach Provides Facility and Energy Staff with technology necessary to enable action Enabling infrastructure for sharing of energy performance data to occupants and tenants Scalable Foundation Smart Grid Ready = enabling infrastructure for Smart building deployment Flexible and scalable for future expansion
