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.

  • key points here circled—126 is the number, Mbtu (shown as ‘mmbtu’) is the unit.
  • Example:872 Therms / 10 = 87 Mbtu11320 kWh / 293 = 39 Mbtu sum: 126 MbtuNotes: 1 therm of natural gas ≈ 100,000 btu 1 kWh of electricity ≈ 3,412 btu
  • Example:872 Therm * 11.7 lb / 2000 = 5.1 T11,320 kWh * 0.99 lb/kWh/ 2000 = 5.6 T sum: 10.7 TAssumes: 11.7 lb of CO2/therm 0.99 lb of CO2/kWh 2000 lb / ton (T)
  • Standard monthly National Grid reporting template – 2 files with dozens of lines of code. One set per HEA.Highlighted yellow fields indicate data fields not available in Earth Advantage – mostly product specific or billing related data
  • High Performance HVAC equipment in Home MPG towns = double the Mass Save rebatePilot’s 8 communities, 6 of which are served by National Grid / CSG: Belchertown, East Longmeadow, Hampden, Monson, Palmer, and Wilbraham

    1. 1. Home MPG:Adding an Energy Performance Score to the Mass Save® Home Energy Services Program ACI New England October 17, 2012 Sam Nutter N.E. Business Development Director
    2. 2. Conservation Services Group (CSG)• Founded in 1984• Nonprofit corporation• ~800 staff responsible for 7,000+ field jobs nationwide• Over 3 million homes and facilities served• Manage the delivery of over $250 million in energy efficiency and renewable energy investments and projects annually
    3. 3. Talking Points1. Mass Save® Home Energy Services2. Integrating the new CSG Energy Performance Score (EPS)3. Data collection, tracking and reporting4. New incentives in the “Home MPG” initiative
    4. 4. 1. Mass Save® Home Energy Services
    5. 5. www.masssave.com/residential 5
    6. 6. Mass Save® Home Energy Services (HES) 6
    7. 7. Mass Save® Home Energy Services (HES)• 4 Lead Vendors  Conservation Services Group  Honeywell Utility Services  RISE Engineering  Center for EcoTechnology• 100 +/- Independent Installation Contractors• 20 +/- Home Performance Contractors 7
    8. 8. Mass Save® Home Energy Services (HES)Program Offerings • No-cost Home Energy Assessment (HEA) including:  CFLs  7-day digital programmable thermostats  Low flow showerheads and faucet aerators • No-cost air sealing where applicable & recommended • Insulation – instant rebates up to $2,000 • Energy efficient refrigerator rebates • High efficiency heating system and hot water heater rebates • High efficiency A/C QIV services and rebates • HEAT Loan – 0% interest; terms up to 7 years 8
    9. 9. Standard Mass Save HES report produced statewide by CSG for National Grid customers
    10. 10. Includes list of items installed during HEA and detailed future recommendations
    11. 11. 2. Integrating the new CSG Energy Performance Score (EPS)
    12. 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
    13. 13. Energy Performance Score (EPS)
    14. 14. 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. 15
    15. 15. Carbon Footprint
    16. 16. 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
    17. 17. 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 18
    18. 18. 3. Data Collection, Tracking and Reporting
    19. 19. Data, Data, ….• Reporting requirements for MA• Transmitted monthly• 99 possible data fields per customer• Use CSG’s EnergyMeasure® 20
    20. 20. …..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 21
    21. 21. 4. New Incentives in the “Home MPG” initiative
    22. 22. New Home MPG Deep Retrofit IncentivesEE Measure Mass Save® HES rebate Home MPG adderInsulation 75% up to $2000 cap 75% up to $1750Propane Furnace with $500 $500ECM Blower, 95% AFUEPropane Hot Water $1000 $1000Boiler, 90% AFUEDuctless mini split, min $500 $500EER 12, min HSPF 8.5Air source heat pumps, $300 $300EER 12.5, HSPF 8.5Air source heat pump $1000 $1000water heaters, EF 2.3 orgreater, 10 year warranty• Note: Terms & conditions apply; must be pre-approved• Expected launch November 2012; Home MPG towns only!
    23. 23. Summary• Mass Save® is a well established, long runningprogram with existing systems and contractors• Integrating an EPS into an existing program can bechallenging (training; time to serve; communication)• Data integration of a new system adds complexity• Home MPG leverages significant federal funding toexperiment with several unique delivery featuresincluding the EPS, widespread infrared imaging, andbonus incentives designed to encourage deeperretrofits and greater savings per home.
