SUPPLEMENTARY INFORMATION:
I. Background
II. Public Participation
I. Background
Title III of the Energy Conservation and Production Act, as amended (ECPA), establishes requirements for building energy conservation standards, administered by the DOE Building Energy Codes Program. (42 U.S.C. 6831 et seq.) Section 304(a)(5)(A), as amended, of ECPA provides that whenever the CABO Model Energy Code, or any successor to that code, is revised, the Secretary of Energy (Secretary) must make a determination, not later than 12 months after such revision, whether the revised code would improve energy efficiency in residential buildings, and must publish notice of such determination in the Federal Register. (42 U.S.C. 6833(a)(5)(A)) The International Energy Conservation Code (IECC) is the contemporary successor to the CABO Model Energy Code specified in ECPA.
The 2018 IECC (2018 edition), the most recent edition, was published in August 2017, triggering the statutorily-required DOE review process. The IECC is developed through an industry consensus process administered by the International Code Council (ICC). The ICC has an established program for regular review of the IECC, identifying whether proposed changes have energy and cost impacts, and incorporating changes approved by the ICC governmental voting body. Updated editions of the IECC are typically published every three years. More information on the ICC code development process is available at: https://www.iccsafe.org/codes-tech-support/codes/code-development-process/code-development-2/.
II. Discussion of Findings
To meet the statutory requirement, DOE conducted a Preliminary Energy Savings Analysis of the 2018 International Energy Conservation Code (Preliminary Analysis) to quantify the expected energy savings associated with the 2018 IECC. The Preliminary Analysis indicates, of the 47 proposed code changes which directly impact energy use, 11 changes resulted in a reduction of energy use, with 3 changes projected to increase energy use. The remaining 33 changes are projected to have no or limited effect on energy usage.
Preliminary Energy and Cost Savings Analysis
DOE's Preliminary review and analysis of the 2018 IECC identified two key changes which result in the bulk of the energy savings associated with the updated code:
- RE31 (Fenestration): Lowers (improves) fenestration U-factors in climate zones 3-8
- RE127 (Lighting): Increases high-efficacy lighting from 75% to 90% of permanently installed fixtures in all homes.
These changes are expected to have a significant and measurable impact on energy efficiency in residential buildings. These changes are expected to increase energy savings, impact a significant fraction of new homes, and can be reasonably quantified through the established methodology.
Together, the key impacts identified above are expected to result in life-cycle cost savings ranging from a low of $398 in climate zone 1 to a high of $1071 in climate zone 8. Expected payback ranges from 0.0 years (immediate payback) in climate zones 1 and 2 to 1.8 years in climate zone 3. National average savings are $480 with a payback of 1.1 years.
More information on these two changes and their expected energy savings impacts are presented in a separate technical analysis, Preliminary Energy Savings Analysis: 2018 IECC Residential Requirements.
Preliminary Determination of Impacts on Energy Efficiency
Review of the 2018 IECC indicates the updated model code will increase energy efficiency in residential buildings. Residential buildings meeting the 2018 IECC (compared to the previous 2015 IECC edition) are expected to incur the following savings on a weighted national average basis:
- 1.68 percent of annual site energy;
- 1.91 percent of annual source energy, and;
- 1.97 percent of annual energy costs.
The full Preliminary Analysis, including an assessment of the expected energy and cost impacts, is available via the DOE Building Energy Codes Program: https://www.energycodes.gov/development/determinations.
