United States of America Reviews Energy Conservation Standards for Equipment and Systems

United States of America is requesting public input on the analytic methods used to set energy conservation standards for a broad range of products including heating and cooling equipment, lighting fixtures, and building systems through a formal request for comments.

Compliance Analysis: DOE’s Request for Comments on Analytic Methods for Energy Conservation Standards

The U.S. Department of Energy (DOE) has issued a Request for Information (RFI) to gather public input on the analytic methods used to set energy conservation standards for covered products and equipment, including heating and cooling equipment, lighting fixtures, and building systems. This RFI is governed by the Energy Policy and Conservation Act (EPCA) and aligns with DOE’s Process Rule at 10 CFR part 430, subpart C, appendix A. Below is a structured breakdown of the key regulatory requirements, analytic topics, and procedural obligations for stakeholders submitting comments.

1. Legal Authority and Regulatory Framework

A. Statutory Requirements

The DOE’s authority to establish energy conservation standards stems from the Energy Policy and Conservation Act (EPCA), as amended¹. EPCA mandates that DOE:

• Set energy conservation standards for covered products and equipment to achieve the maximum improvement in energy efficiency that is technologically feasible and economically justified¹.
• Consider factors such as consumer life-cycle cost (LCC), manufacturer impacts, energy savings, and environmental effects in its analyses¹.
• Ensure standards do not significantly reduce product utility or availability or disproportionately harm small businesses¹.

B. Process Rule and Analytic Methodology

DOE’s Process Rule (10 CFR part 430, subpart C, appendix A) outlines the procedures for setting and revising standards. The current RFI seeks input on:

• Analytic methods supporting the Process Rule, including engineering analyses, life-cycle cost (LCC) calculations, and manufacturer impact analyses¹.
• Updates to the Process Rule to reflect recommendations from the National Academies of Sciences, Engineering, and Medicine (NASEM) report¹.
• Discontinuation of emissions impact analysis in economic justification determinations, per the Secretary’s discretion under EPCA¹.

2. Key Analytic Topics and NASEM Recommendations

DOE’s RFI focuses on several analytic areas, many of which align with NASEM’s recommendations. Below is a summary of the critical topics and corresponding regulatory requirements:

A. Problem Statement and Market Failure

1. Uncertainty and Variability
   • DOE must account for variability in inputs (e.g., energy consumption, costs, consumer behavior) and uncertainty in model outputs¹.
   • NASEM recommends:
   • Prioritizing critical inputs (e.g., geographic/temporal variability in energy use)¹.
   • Probabilistic assessments to propagate uncertainty through analyses (e.g., presenting results as ranges rather than point estimates)¹.
   • Ex post analyses to validate assumptions and improve future standards¹.

B. Technology Assessment

• Technology Readiness Levels (TRLs): NASEM suggests DOE adopt alternative methods (e.g., NASA’s TRL taxonomy) to evaluate technology feasibility and avoid excluding innovative options¹.
• Technology Evolution: DOE requests input on how to model technology adoption independent of standards and whether current Trial Standard Levels (TSLs) and Efficiency Levels (ELs) reflect standard-driven adoption¹.

C. Economic Justification Under EPCA

EPCA requires DOE to evaluate standards based on:

1. Consumer Effects
   • Life-Cycle Cost (LCC) Analysis: DOE must estimate consumer costs and savings over the product’s lifetime, accounting for geographic/temporal variability¹.
   • Consumer Choice Modeling: NASEM recommends:
   • Discrete choice models to quantify trade-offs between product attributes (e.g., energy savings vs. performance)¹.
   • Ex post data collection on consumer behavior to validate assumptions¹.
   • Rebound Effects: DOE should consider real-world energy consumption (e.g., in-situ metering) rather than relying solely on test data¹.

1. Manufacturer Effects
   • Cost Pass-Through: DOE must model how manufacturers pass compliance costs to consumers, accounting for demand/supply elasticities and secondary markets¹.
   • Industry Consolidation: DOE seeks input on how to account for consolidation and price discrimination in analyses¹.
   • Markups Analysis: NASEM recommends ex post and market-based evidence to project realistic price effects¹.

1. Market Effects
   • Product Differentiation: DOE should model how standards affect product variety and competition¹.
   • Price Forecasting: NASEM suggests using marginal cost changes (rather than inflation indices like PPI) to predict price impacts¹.

1. Emissions (Discontinued for Economic Justification)
   • DOE no longer considers emissions impacts in economic justification determinations, per the 2026 Process Rule proposal¹. However, NASEM recommends:
   • State-level hourly load curve analyses to estimate emissions changes under different decarbonization scenarios¹.
   • Grid efficiency benefits (e.g., demand response readiness) as economically valuable¹.

D. Data Collection

NASEM emphasizes the need for rigorous, disaggregated data to improve analytic models:

• Ex Post Analyses: DOE should collect data on consumer/producer behavior, energy consumption, and environmental impacts post-standard implementation¹.
• In-Situ Metering: Real-world energy use data (e.g., from Pecan Street or LBNL) may better capture rebound effects than test data¹.
• Surveys and Studies: DOE relies on sources like:
  • Residential Energy Consumption Survey (RECS)¹.
  • American Housing Survey (AHS)¹.
  • Lawrence Berkeley National Laboratory (LBNL) reports¹.

E. Effects on Power Systems

NASEM recommends integrating power system benefits into cost-efficiency calculations:

• Demand Response Readiness: Standards should credit features enabling grid efficiency (e.g., smart appliances)¹.
• Hourly Load Curve Analysis: DOE should estimate state-level emissions changes using tools like the National Energy Modeling System (NEMS)¹.

3. Summary of Public Comment Topics from the Process Rule RFI

DOE’s 2025 Process Rule RFI received comments on the following analytic methodologies, many of which overlap with NASEM recommendations¹:

4. Submission Requirements for Public Comments

A. Deadline and Methods

• Deadline: Comments must be submitted by September 8, 2026¹.
• Submission Methods:
  1. Federal eRulemaking Portal:¹(https://www.regulations.gov) (Docket No. EERE–2022–BT–OT–0004)¹.
  2. Email: ASmethodreview2022OT0004@ee.doe.gov (include docket number in subject line)¹.
  3. Postal Mail:

“` Appliance and Equipment Standards Program, U.S. Department of Energy, Building Technologies Office, Mailstop CM–5B, 1000 Independence Avenue SW, Washington, DC 20585–0121<sup>1</sup>. “`

B. Content Requirements

DOE encourages submissions of:

• Data (e.g., disaggregated energy use, consumer behavior studies)¹.
• Peer-reviewed studies supporting analytic improvements¹.
• Ex post analyses of prior standards¹.
• Recommendations on implementing NASEM’s suggestions (e.g., discrete choice models, probabilistic assessments)¹.

5. Executive Order Alignment

DOE’s RFI complies with Executive Order 14154 (January 20, 2025), which mandates:

• Public comment opportunities for energy regulations¹.
• Peer-reviewed scientific analysis¹.
• Separate reporting of global vs. domestic costs/benefits¹.
• Market competition and innovation in appliance industries¹.

Summary Answer

The DOE’s Request for Information (RFI) on analytic methods for energy conservation standards seeks public input on improving the assumptions, models, and data underpinning standards for covered products (e.g., HVAC, lighting, building systems) under the Energy Policy and Conservation Act (EPCA)¹. Key focus areas include:

1. Economic justification analyses (life-cycle cost, consumer choice modeling, manufacturer impacts)¹.
2. Technology assessment (TRLs, ex post data collection)¹.
3. Power system effects (demand response, grid efficiency)¹.
4. Data collection (in-situ metering, disaggregated surveys)¹.

DOE has discontinued emissions impact analysis for economic justification but seeks input on NASEM’s recommendations for grid-related benefits¹. Comments must be submitted by September 8, 2026, via the Federal eRulemaking Portal, email, or postal mail¹. Stakeholders should provide data, peer-reviewed studies, and ex post analyses to support proposed methodological improvements¹. The RFI aligns with Executive Order 14154, which emphasizes public participation and scientific rigor in energy regulations¹.
