Presentation – Focus Areas

2

• GSA’s Approach and current system architecture

• Challenges maintaining competition• Metrics across Enterprise – comparisons

across agency portfolio• On-Going Metering/System Support for

Complex system• Lessons Learned – Biggest benefits/ Successes• Challenges overall

GSA’s Advanced Metering Plan• Development of Agency Plan

– What are the objectives?• Meet mandates• How are we going to use Metered Data?

– Current and Future Metering Needs

• Agency Implementation Plan – Dec 2015

• Initial Priorities ( Still meet Practibility test)– Covered Facilities (EISA07) – Top Energy Users (196 facil)– Sites receiving ARRA Funding– Bldgs where Financing Energy Project– Bldgs with onsite generation (PV, Cogen, Wind turbines)– New Construction




GSA’s Advanced Metering Program – Status

6

• Inventory (Approx 40 Unique Vendors- IP Enabled / 6 ETLs)– Just under 700 IP Enabled Devices– Total of 5,300 Enabled Sources Devices– 40,000 Source Measurement Pairs

• Energy/ Water – Advanced Metering

• On-Going Efforts– New sites– Finishing up Gas/Steam/ Water– Sub-Metering (tenant/ Equipment/ Speific loads)

• Challenges – Cost/ Resource Reality Check– Support Resources– IT Security Requirements– Guidance documents ( next slide)– Competition- Creates diverse architecture – complicates support and Security process

and ongoing needs– Accurate Inventory Tracking– Legislative Metrics BTU/GSF vs Metered Metrics ( next slide)– Cost/ Resource Reality Check

GSA’s Advanced Metering Program –One Front End across agency

7

• Benefits– One Front End – Simplifies sharing among peers

– Troubleshooting – Support Contract similar issues for all regions so economies of scale for contract

– Great for Legislative Reporting – such as Renewable Energy

– One Approach for using metered data for other programs (next slide)


GSA’s Advanced Metering Program –Analysis Across Portfolio

8

• All sites don’t use same Fuel Sources

• Not cost effective to install Adv Metering for all fuel types at a site

• BTU/GSF metric difficult if not all fuel sources metered

• Educate User Community about metrics

• Meaningful comparisons – Important– kWh/gsf instead– Baselining - % of Peak– Start- Up / Shut- Down times

Use of Metering Data (Agency – Enterprise View)

10

Energy Procurement• Load Aggregation• Load Factor• Participating in demand

response programs

Benchmarking• Baseline comparisons• Start-Up Comparisons• Energy/Water intensity • Trends across similar bldg types

Verification for Reporting Mandates

(Renewable Generation)

Promote energy awareness

& Sharing Lessons Learned


Use of Metering Data(Bldg Perspective)

11

Energy billing & procurement•Verifying utility bills

Bill Auditing •Tenant energy use (sub

metering)• Identifying best rates•Participating in demand

response programs

Optimize/Review performance•Diagnose equipment & systems

operations•RETUNING•Benchmark utility use• ID potential projects• ID power quality problems•Modelling (more adv users)•On-Site Generation monitoring

Verify project performance

Promote energy awareness

Demand Response Programs• Monitor actions when response needed• Measure results• ID potential savings from DR


How can Metering Improve my Bldg’sOperation and Efficiency

12

• Identifying anomalies in usage patterns• Start up and shut down schedules not matching what should

be• Overtime Utility usage• Baseloading info – comparison to similar sites• Observing during Load curtailment events• Watch impact on consumption by adjusting schedules• Monitor Consumption vs. Index pricing – adjust….• Leak detection• ADVANCED: Modelling/ Power Quality Analysis


How we are ACTUALLY using the Data

13

• Engaging (Partnering) O&M Staff/ Energy Teams– Reviewing trends daily / periodically – asking questions, Why ? Should this be

occurring?– Finding Leaks (Water)– Modifying our O&M Specs to require review of data– Provides oversight to our O&M, not possible before, especially in remote sites

• Using Report Subscription Capability– O&M Staff/ Senior Mgmt

• Making Models to validate suspicions• Re-Tuning

– Proper analysis of utility and interval meter data can result in the identification of significant energy savings opportunities and possibly improve overall building operations.

– Using it with First Fuel Software (Rapid Bldg Assessment)



Regional Sites – Keep it Simple

What causes difference in baseloads w/ similar bldgs?

Start-Up / Shutdown differences?

Start-Up Spike setting peak for day

GSA’s Advanced Metering Program –Enterprise Wide System

21

• Challenges– All devices must be scanned – Time consuming / Resource drain– Communication breakdown – to every person who might be

working on a advanced metering project– Changes to Firmware– Password / Credential requirements– Ensuring as devices installed meet Remediation Plans

• Lessons Learned /Successes– Importance of sharing successes to keep funding available –

Demonstrate the benefits– Support Contract that facilitates resolution and tracking of Issues– Some level of standardization is beneficial – On-Going sharing is a must….– Careful what you wish for… growth to fast for system

parameters… Cloud options
