Development of Savings Protocols for Emerging Technologies and Program Approaches

Project Sponsor:

Regional Evaluation Monitoring and Verification Forum;

Northeast Energy Efficiency Partnerships (NEEP)

ers


Emerging

Technologies: Proposed for Program Implementation

Recent Portfolio Additions

Established but Advancing Rapidly

Program Approaches Not Widely Implemented

Not Fully Evaluated

ers


Close Knowledge Gaps & Establish Protocols

Emerging Technologies

Ductless Mini-Split Heat Pumps

Heat Pump Water Heaters

Solid State/LED Lighting

Set-top Boxes

Advanced Power Strips

Biomass Pellet Boilers & Furnaces

Program Approaches

Commercial Lighting Design

Commissioning & Retro-Commissioning

Whole Building Retrofits

ers


Ductless Heat Pumps

Knowledge Gaps Heating Performance of New Low-Temperature Rated Units

Performance of Recent High Efficiency Models

Homeowner Experience; Control & Comfort

Performance as Supplemental System

EM&V Recommendations

Monitor Indoor and Outdoor Temperatures

Monitor Consumption of DHP and Central System (if any)

Interview Homeowners

ers


LED Lighting

Knowledge Gaps What are LED’s Replacing;

Incandescent, CFLs

Lumen/Lumen the Right Metric

Do Operating Hours Differ from Conventional Lighting

Persistence Factors and Measure Life

How EISA Affects Markets and Savings Calcs

ers


LED Lighting


Residential

Adopt Deemed Values for Common Products Socket Surveys & Customer Interviews – Satisfaction; Life;

Persistence

Commercial – Including Upstream

Adopt Deemed Values for Common Products Develop Algorithms – Lumen/Lumen with Adjustment Factors Participate in National/International Efforts (DLC)

ers



Knowledge Gaps

Typical Install Locations for Geographic Region

Heat Pump or Hybrid Operation

Savings Effects of HW Demand & Storage Sizing


Assure that Savings Protocols Include:

Ambient Temperature Factors Sizing Considerations Net Effects if Outdoor Ducted

Develop Deemed Values

ers



BPA Performance Testing

ers



Knowledge Gaps

Persistence

Product Compatibility

Proper DIY Installation


Residential

Interview Purchasers 3-6 Months Following Installation Track Success of DIY vs Professional Install

Commercial

Monitor Consumption Pre – Post Install or with Control group

ers


Biomass Pellet Boilers & Furnaces

Knowledge Gaps Conventional Fuel Replacement or Partial Displacement

Persistence of the Savings vs Advancing Heat Pumps and Gas Systems

Fuel Supply Stability


Treat the Measure as Pure Fuel Switch

Or; if Program is GHG Focused; Fuel Neutral, Source Calculation

ers


Set-Top Boxes

Cable; Satellite; Gaming; Streaming Knowledge Gaps

Progress of New Models

New Equipment or Refurbished

Decisions - National or Regional Basis


Engage the Service Providers

Supplement National Study Data with Local Studies on Usage Patterns

ers


Program Approaches

Commercial Lighting Design Base Calculations on LPD & Deemed or Recorded Operating

Hours

Require Lighting Quality Best Practice

Support Advanced Technologies

Commercial Commissioning Establish a Site Specific Baseline

Monitor Pre/Post Consumption

Establish Schedule for Continuous Improvement

ers


Program Approaches

Whole Building Retrofit Programs Develop Fuel Neutral Approach

Modeling, Billing Analysis, Monitoring all Valid Approaches

Billing Analysis and/or Monitoring to Calibrate Models

Unregulated Fuels (oil, biomass) Present Challenges

Develop Algorithms that Incorporate Interactive Effects

ers


Project Next Steps

Forum Selected Technologies for Primary Research

Ductless Heat Pumps

• Monitor 35 Installations: Maine, New York, Mid Atlantic

• Verify Cold Weather Performance • Verify Homeowner Usage Patterns


• Survey 100 Residential Purchasers • Monitor 40 - 80 Commercial Installations • Verify Savings and Persistence
