3 Evaluation Research Areas: Residential, Commercial & Industrial, Special &
Cross-Sector Studies
Residential research areas will be divided into three categories today:
11
Residential Studies: This research area was divided by program delivery method. Whole House typically has a direct install delivery strategy. Products is generally an upstream delivery strategy. Heating and Cooling is typically is delivered through influencing contractor and distributor prevailing practices. We recognize that there can be overlap between all three areas. Residential Research

Study Completion Date Key Data Collection Elements Program Delivery and HEAT Loan Assessment April 2015* Interviews with participants and contractor Realization Rate Assessment June 2013 Billing and engineering analysis, simulation modeling Pre-Weatherization Initiative April 2013 Interviews with participants and stakeholders; review of tracking data Packaged Measure Initiative June 2012 Review of tracking data Net-to-Gross June 2012 Interviews with participants and contractor, discrete choice modeling Impact Evaluation August 2012 Billing and engineering analysis, simulation modeling *In progress.
What did we learn?
- LV and HPCs overestimate per-measure gross savings.
- Cross-participation rates between HES, Cool Smart, and HEHE
were lower than anticipated.
- Participants install measures that capture, on average, 44% of
identified audit savings.
- HPCs trail behind LVs with respect to HEAT loan and cross-
participation and installing HES heating/water heating systems.
- The program causes insulation contractors to improve practices
at nonparticipating sites (spillover).
2/24/2015 18
Remaining Research Questions
- Can program design changes encourage deeper savings,
greater measure adoption, and cross-participation?
- Does the current realization rate adjustment to ex ante savings
remain appropriate?
- Does similar insulation SO occur as part of the MF program?
- Are the current NTG assumptions still appropriate?
- What opportunities exist for home automation savings?
- What about the current DI CFL NTG (73%) post-EISA?

What did we learn?
- Significant weatherization savings (29% of SF heating usage);
greater than HES (263 vs. 149 therms).
- Opportunities exist for standardizing savings estimates across
CAPs and PAs as well as the QA/QC process.
- LI customers use their lights similarly to non-LI customers.
- Weatherization likely reduces LI customers’ need to use
supplementary electric space heaters.
- Minimizing the points of contact (for MF) may increase
participation.
- Completing a billing analysis requires information not
captured electronically.
2/24/2015 22
Remaining Research Questions
- Have measure savings estimates been appropriately
standardized?
- Does the program maximize lighting savings?
- Which LIMF measures require MF-specific savings or
assumptions?

Study Completion Date Key Data Collection Elements
Multifamily Impact Evaluation June 2015* Billing analysis Multifamily Process Evaluation February 2015* Interviews with stakeholders and contractors; customer focus groups, in-depth interviews and phone surveys; literature review; on-site visits; and data review Multifamily Program Impact Analysis July 2012 Data review; savings algorithm review Multifamily Process Evaluation June 2012 Stakeholder interviews; literature review; participant and nonparticipant focus groups and phone surveys; and data review Multifamily Market Characterization & Potential Study May 2012 Stakeholder workshops and on-sites visits Residential New Construction 4-8 Story Multifamily Pilot April 2012 Stakeholder and participant interviews *In progress.
What did we learn?
- A single point of contact would improve the customer
participation process.
- Program tracking is insufficient for “linking” multifamily
properties across fuels and programs (e.g., C&I and Residential).
- The current audit process leaves room for missed and
lost opportunities.
2/24/2015 26
Remaining Research Questions
- Beyond expanding the MMI, what options are available for
creating a single point of contact?
- Is it feasible to create a link between C&I and Residential
multifamily customer data?

Study Completion Date Key Data Collection Elements Ductless Heat Pump Metering December 2015* Collected to date: Additional baseline information from participant interviews HEHE Impact Evaluation February 2015* High efficiency boiler/furnace metering, spot measurements of baseline equipment, billing data disaggregation Furnace Baseline Assessment December 2014 Review of market data, previous MA research Ductless Heat Pump Survey September 2014 Participant understanding of DMSHP installation, motivations, and perceptions of program involvement NTG Study June 2013 Surveys with participants, contractors, distributors *In progress
What did we learn (about furnaces)?
- Participant homes with furnaces consume less gas than other
homes–drives lower furnace savings than TRM.
- Standard efficiency furnaces perform slightly higher than
ratings.
- High-efficiency furnaces perform at their ratings.
- Program baseline is moving to 85% AFUE.
- Net-to-gross (for AFUE >= 95%) is 81%.
2/24/2015 30
What did we learn (about boilers)?
- High-efficiency boilers perform worse than their ratings; they
are not being controlled to maximize potential savings– an
- pportunity for higher savings.
- Standard efficiency boilers also perform worse than their
ratings due to stack losses–drives higher savings than TRM.
- Participant homes with combination boilers (combined
heating and small hot water tank) consume less gas than
- ther homes–drives lower savings than TRM.
- Most (~75%) participating standalone boilers were attached
to indirect hot water tanks–drives higher savings than TRM.
- Net-to-gross is 77%.
2/24/2015 31
Remaining Research Questions (Gas Heating Equipment)
- How can contractor installation practices be improved to capture
lost condensing boiler opportunities?
- How can programs influence people to change from non-condensing to
condensing equipment before the end of the useful life, and what’s the appropriate baseline for that sort of program design?
- Can smart thermostats improve the performance of condensing gas
boilers?
- What market effects are associated with the program’s market
intervention?
- What is the appropriate NTG to account for FR, SO, and other market
effects?
- What are the true incremental costs of equipment?
- What is the true lifetime of this equipment?
32
What did we learn about Ductless Heat Pumps?
- In 2013, DMSHPs primarily were installed in retrofit projects, either
to displace existing heating equipment or to provide a new cooling
- amenity. In 2014, units are going into WMECO’s new construction.
- DMSHPs are more often installed for cooling than heating.
- DMSHPs are not replacing existing heating systems, only
supplementing and offering an improved level of comfort.
- Participants who installed “cold climate” DMSHPs are generally
more positive about their heating performance.
- DMSHP usage is not always rational (i.e., some people should
displace oil heating and are not).
2/24/2015 33
Remaining Research Questions – Electric HVAC equipment
2/24/2015 34
- Do we understand DMSHPs?
– How are they being used? – What are they replacing? – What are the savings?
- Do contractors really understand what they are selling? Are they
correctly sized?
- What is the interaction of DMSHPs with other heating systems?
- Can smart thermostats be used to both optimize DMSHP usage
while increasing or maintaining occupant comfort?
- Similar to gas equipment, what are the following:
– Market effects that need to be considered in NTG? – True incremental costs of electric HVAC equipment? – True lifetimes of electric HVAC equipment?

– Most suppliers say the market is good or excellent.
- CFL market share stable in MA, decreasing elsewhere.
- Halogen market share stable in MA, increasing nationally.
– CA data suggest jump in 2013 due to full implementation of EISA; some programs dropping CFL incentives.
- Availability, diversity of LEDs on store shelves increasing.
- LED prices falling, but price still seen as a barrier.
- CFL prices increase in the absence of incentives.
- Consumers who use LEDs also use CFLs.
2/24/2015 37

2/24/2015 40
What did we learn?
- Most households in MA use CFLs; over 1/5 use screw-in LEDs.
- CFL saturation up five percentage points from 2013 to 2014.
– Now 33%; had crept from 26% in 2009 to 28% in 2014.
- LED saturation at 3%, but rising steadily over time.
- Saturation not much higher in MA vs. KS but higher than GA.
- CFLs most common bulb type used to replace removed bulbs.
– Includes incandescents, CFLs, LEDs (but only five LEDs in sample).
- LEDs, incandescents equally likely to replace CFLs not replaced
by other CFLs.
2/24/2015 41
Remaining Research Questions

2/24/2015 44
What did we learn?
- Suppliers strongly argue to maintain standard CFL incentives.
– Believe program incentives limit EISA-related backsliding. – Cite increased halogen sales and market share in CA in 2013. – Supported by POS data analysis for CA.
- Purchasing 2014/2015 data would allow further exploration.
- Increase in Fall 2013 in shelf space devoted to incandescents.
– Both participating and formerly participating retailers.
- Some consumers stockpile incandescents, not widespread.
2/24/2015 45
Remaining Research Questions
- How long should MA continue to support standard CFLs?
- Balance possible backsliding with cost-effectiveness, decreasing
delta watts/measure life (EISA 2020).
- How did CFL, LED, and halogen market share fare?
- Compared over time.
- Compared to CA and NY (natural experiment). What will be the
impact of EISA on socket saturation?
- Does EISA lead to changes in bulb replacement strategies?

2/24/2015 48
*Prior studies dating back to late 1990s.
What did we learn?
- Saturation rates among low-income households higher than
- ther households.
– Smaller homes = fewer sockets so easier to achieve high saturation. – Direct installation plays a role, but not the whole story.
- Suppliers generally agree with PA approach of focusing on
particular retail channels and customer base to reach HTR.
– Some argue HTR shop where non-HTR households shop (e.g., home improvement, mass merchandise). – On-site studies confirm that home improvement, mass merchandise the most common places low-income buy bulbs. – BUT low-income consumers do cite discount stores more frequently.
2/24/2015 49
Remaining Research Questions
- What are the lighting purchases, use habits, and saturations of
linguistic minorities, recent immigrants, and people with physical or developmental disabilities?
- How effective are current retail channel and store-customer-base
approaches to increasing efficient bulb use among HTR customers?
- Is a retail-based program an effective strategy for increasing
saturation among the most HTR, or should the PAs instead rely on direct-install programs?
- Which community partners could assist the PAs in identifying the
best ways to increase saturation among HTR customers?
