11. Appliance standards basics
Minimum energy and water efficiency levels for appliances and equipment
National level - standards apply to the manufacture and import of products
About 55 products now covered
State level – standards apply to sale or installation of products

12. Research questions
With so much progress to date, especially over the past eight years, what is the potential for future savings with updates to existing national standards?
What strategies could be employed to further increase savings available from standards (within the constraints of existing law)?

14. Methodology
Savings through 2050 from post-2016 standards for 45 products based on:
existing technology
product scopes
test procedures
Estimates of final rule and compliance dates based on statutory requirements
Compliance dates:

15. Methodology (cont’d)
Baseline: current standards or standard levels recently proposed or finalized
Efficiency levels analyzed:
For most products, max-tech level from most recent DOE rulemaking
For plumbing products (faucets, showerheads, toilets, urinals), CA standards
Assumptions for compliance rates absent a new standard:
For products without an ENERGY STAR specification: 10%
For products with an ENERGY STAR specification: 25%

19. Findings: annual utility bill savings

20. Findings: national cumulative savings through 2050
70 quads of energy
17.5 trillion gallons of water
3.5 billion metric tons of CO2
$1.1 trillion on utility bills

21. Findings: Southeast annual savings

$319 billion on utility bills

23. Top 10 products

24. Top 10 products: water heaters
16.2 quads and $233 billion
Electric storage water heaters: ~50% savings with heat pump technology (1,090 kWh)
Gas storage water heaters: ~25% savings with condensing technology (3.6 MMBtu)

25. Top 10 products: showerheads and faucets
5.3 quads and $153 billion (showerheads); 3.6 quads and $130 billion (faucets)
Standards unchanged since 1992
Current standards: 2.5 gpm for showerheads; 2.2 gpm for faucets
New CA standards: 1.8 gpm for showerheads and kitchen faucets; 1.2 gpm for lav. faucets

26. Top 10 products: central air conditioners and heat pumps
6.6 quads and $95 billion
2023 standards (pending DOE final rule)
ACs: SEER 15 for the south and SEER 14 for the north
HPs: SEER 15
Analyzed standard levels of SEER 17 for ACs and SEER 21.8 for heat pumps
10-15% savings for ACs
25% savings for HPs
Can be met with variable-speed compressors, improved heat exchangers, and more-efficient fan motors

27. Top 10 products: Clothes dryers
4.8 quads and $68 billion
Electric clothes dryers consume more than refrigerator, clothes washer, dishwasher combined
ENERGY STAR Emerging Technology Award for clothes dryers that save ~40% in their most efficient setting
Heat pump dryers recently introduced to US market
Analyzed standard levels that represent savings of 30%
250 kWh
0.9 MMBtu

28. Top 10 products: Electric motors
4.3 quads and $44 billion
2016 standards for hp three-phase induction motors: NEMA Premium (IE3)
Analyzed standards roughly equivalent to “Super Premium” (IE4) levels
~15% reduction in losses
Can be met by conventional induction motors as well as by advanced motor technologies

29. How to further increase savings
Invest in improved test methods, including expedited updates for top priorities
Systematically assess opportunities to expand scope and conduct rulemakings for the biggest new opportunities
Continue to improve analysis methods and data sources.

30. How to further increase savings (con’t)
Consider how DOE test methods, ratings, and standards can realize or facilitate systems savings opportunities
Develop a strategic approach to address connected products

31. Example: Improved dryer test methods
Issues with current dryer test method
Uses test cloths not representative of real-world clothing
NEEA data shows >1/3 of loads dried in the field are significantly smaller than DOE test load
Current test method doesn’t encourage technologies that could improve efficiency of drying small loads
Testing on only the “normal” cycle
Presents a risk of potential gaming

32. Example: Improved dryer test methods
Suggested improvements
Include a more realistic test load
Add a test with a smaller load size
Include testing with multiple cycle settings
