News from Codes for Climate
|
|
The initial subcommittee and consensus committee process for hearing International Energy Conservation Code (IECC) 2024 code change proposals is winding down, with the draft IECC 2024 estimated to be released for public comment in the late summer/early fall. The final timelines for public comment will be available shortly and the Codes for Climate team will keep this group posted on informational content around the draft, as well as the opportunity to collaborate on submitting comments.

Codes and Standards Development Updates
The International Code Council (ICC) residential and commercial code development process for the 2024 IECC is ongoing. Committee and subcommittees meet frequently to evaluate code change proposals. Over the past month, the full consensus committees approved several NBI code proposals, including a number of proposals that will improve the efficiency of existing buildings including:
-
CEPI-217 which requires existing buildings undergoing an addition, alteration or change of occupancy to be more efficient by obtaining a certain number of energy credits in Section C406
-
CEPI-219 which requires new ducts serving additions to be tested
-
CEPI-227 which requires new HVAC systems replacements in existing buildings to have code compliance controls
-
CEPI-228 which requires new HVAC equipment in existing buildings to be sized correctly which reduces energy use, comfort, increases equipment lifetime, and improves dehumidification
-
REPI-144 which adds a requirement that large additions and large alterations to existing buildings include additional efficiency options from R408
-
REPI-86 which improves and clarifies key duct testing criteria and application to improve compliance and verification
-
REPI-89 which improves and clarifies the application of hot water pipe insulation
-
REPI-93 which expands the requirements for HRV/ERV to be included in climate zones 5 and 6
-
REPI-18 which shifts the additional efficiency requirements of R408 from packages to minimum number of credits based on a range of additional efficiency measures
-
REPI-161 which clarifies the renewable energy terminology used in the Zero Energy Home Appendix (Appendix RC)

A number of proposals were also approved by the full commercial committee to improve the integration of buildings with the electric grid which will not only reduce carbon emissions but improve the resiliency of the grid. These measures include:
-
CEPI-7 which requires new commercial buildings to either install an energy storage system or have the space and electrical infrastructure for a future energy storage system
-
CEPI-99 which requires new thermostats to be demand responsive
-
CEPI-125 which requires new electric water heaters to be demand responsive
-
REPI-90 which requires grid-integrated controls on electric storage water heaters
- Note that modifications to CEPI-99 and CEPI-125 resulted from a collaboration between NBI and the Air Conditioning Heating and Refrigeration Institute (AHRI).
The final proposal, CEPI-84 which was approved by the full commercial committee addresses the energy efficiency of indoor horticultural operations by requiring efficient dehumidification techniques.
The status of key NBI-submitted proposals from past months’ consensus committee meetings is available here. For more information about upcoming meetings, see the ICC Codes and Standards calendar.
