Sam Nutter delivered this conference presentation about integrating the new CSG Energy Performance Score into the Mass Save® program. Mass Save is a well established, long running residential retrofit program with existing systems and contractors. Integrating an Energy Performance Score into an existing program can be challenging (training; time; communication). A significant magnitude of data integration of a new system adds complexity. Home MPG leverages federal funding to experiment with unique delivery features including the EPS, widespread infrared imaging, and bonus incentives designed to encourage deeper retrofits and greater savings per home.

9. Standard Mass Save HES report produced statewide by CSG for National Grid customers

10. Includes list of items installed during HEA and detailed future recommendations

11. 2. Integrating the new CSG
Energy Performance Score
(EPS)

12. Why Do We Need an EPS?
• Test consumer acceptance of new format
• EPS provides additional information for consumers
 Compares their home to local averages
 Shows before and after ratings – goal setting
 Provides environmental information
• Test consumer understanding of principles presented

14. Energy Performance Score (EPS)

15. Energy Performance Score (EPS)
• Million btu of energy consumed by house
– Million btu AKA: Mbtu or mmbtu
– Electric and fossil fuel treated as equal (site basis)
– As estimated by the model (not from billing)
• “Asset-based”
– Eliminate occupancy factors
– Standard assumptions about thermostat settings,
appliance/lighting use, etc.

16. Carbon Footprint

17. Carbon Footprint
• Based on state-average carbon emissions
• Major fuel(s) and electricity in house model
• Source: EIA/DOE (eGrid database)
– By eGrid subregion
17

18. Integrating the EPS Scorecard
• Why not use the Earth Advantage EPS?
Both modeling tools produce similar results, but…
• Mass Save® HES provides “turnkey” services:
 Energy Assessment report
 Customer contract for weatherization work
 Work orders and change orders for contractors
 Inspection reports, quality assurance tracking
 Invoices, instant rebates, and customer receipts
 Data reporting for National Grid and MA DOER
• Easier to add EPS to our system

19. 3. Data Collection,
Tracking and Reporting

20. Data, Data, ….
• Reporting requirements for MA
• Transmitted monthly
• 99 possible data fields per customer
• Use CSG’s EnergyMeasure®
20

21. …..and MORE Data!
U.S. DOE reporting requirements
• Different than MA reporting
• 215 line spreadsheet
 each line = data field
 despite length, not enough flexibility
for complex homes (ex. multiple attics)
• 1 column per customer
• Requires new data transfer protocol
• Some data fields require translation
(inches vs. R-value) or manual data entry

22. 4. New Incentives in the
“Home MPG” initiative

23. New Home MPG Deep Retrofit Incentives
EE Measure Mass Save® HES rebate Home MPG adder

• Expected launch November 2012; Home MPG towns only!

24. Summary
• Mass Save® is a well established, long running
program with existing systems and contractors
• Integrating an EPS into an existing program can be
challenging (training; time to serve; communication)
• Data integration of a new system adds complexity
• Home MPG leverages significant federal funding to
experiment with several unique delivery features
including the EPS, widespread infrared imaging, and
bonus incentives designed to encourage deeper
retrofits and greater savings per home.
