IECC Residential Proposals

2021 IECC: Flexibility for the Future | 2021 IECC: Ready and Resilient | 2021 IECC: Commercial

The following proposals have been submitted to the residential energy code by NBI and the Northwest Energy Codes Group. These proposals address a wide range of issues and improve the code by adding additional efficiency, clarifying requirements and creating greater flexibility for both code users and local jurisdictions.


Definitions

CE31-19 Part 2: Residential Renewable Definition. The residential section references renewable energy but does not include a definition for renewable energy. This proposal introduces a definition for renewable energy that is consistent with the definition from the commercial section. Proponent for this proposal is Jim Edelson, representing New Buildings Institute.


Envelope

RE14-19: Grade 1 Insulation Installation. This proposal requires that insulation be installed to the specifications of Grade 1 insulation defined in RESNET/ICC Standard 301. This will ensure that insulation is installed to function effectively. Proponent for this proposal is Eric Makela, representing Northwest Energy Codes Group.


Systems

RE107-19: Pilot Light Prohibition. This proposal prohibits the use of standing pilot lights in most natural gas equipment and appliances. Proponent for this proposal is Nicholas O’Neil, representing NW Energy Codes Group.

RE133-19: Whole House Ventilation Fans. This proposal updates the efficiency requirements for fans used for whole-house ventilation. The existing requirements are based on version 2 of the EnergyStar requirements for fan. This proposal updates the table of requirements with the efficiency levels that correspond to the current version of EnergyStar. These efficiency requirements are still below the average efficiency of fans available on the market. Proponent for this proposal is Eric Makela, representing New Buildings Institute; Mike Moore, representing Broan-NuTone.


Lighting

RE7-19: Residential Lighting Efficacy. This proposal updates the definition of “high efficacy lamps” to reflect the current market of energy efficiency lighting. It also updates the definition so that it accommodates high efficiency LED luminaires that utilize integrated LEDs instead of lamps. Proponent for this proposal is Eric Makela, representing New Buildings Institute.

RE148-19: Residential Exterior Lighting. This proposal adds a requirement for R-occupancy buildings (such as multifamily buildings) to meet the exterior lighting requirements in the commercial section. These buildings are technically commercial occupancies but are subject to the residential code, and therefore have no efficiency requirements for site lighting. Proponent for this proposal is Eric Makela, representing New Buildings Institute.


R406 Energy Rating Index

R204-19: Residential Renewable Energy Credits . This proposal impacts who may claim the environmental attributes of an onsite-renewable energy system. The environmental attributes of solar power, or other renewable energy, have market value that is reflected and transacted in Renewable Energy Credits (REC). It adds a definition for RECs and a requirement that those environmental benefits remain with the building if the energy is to be considered “renewable” for the purposes of the code. Proponent for this proposal is Jim Edelson, representing New Buildings Institute.


Proposed R407 Flex Points

RE207-19: Flex Points Additional Energy Efficiency. This proposal creates a “flex points” requirement similar to the mandatory efficiency options in C406 of the commercial section of the energy code. The proposal requires projects to select additional efficiency options equal to achieve a points target. There are several options provided, covering all aspects of building performance. Proponent for this proposal is Eric Makela, representing New Buildings Institute.


Zero Energy Residential Appendix (RE223)

RE223-19: Appendix RB Zero Energy Residential Appendix. This proposal creates an appendix that would provide cities and states a standard to define a zero energy home using the ERI compliance approach. Proponent for this proposal is Eric Makela, representing New Buildings Institute; Lauren Urbanek, representing Natural Resources Defense Council.

Electric Vehicles

CE217-19 Part 2: Electric Vehicle Ready This proposal creates requirements to provide residential homes with dedicated branch circuits for electric vehicle charging in order to support greater deployment of electric vehicles. It includes minimum thresholds that are appropriate for single family and multifamily residences. Proponent for this proposal is Matt Frommer, representing Southwest Energy Efficiency Project; Eric Makela, representing New Buildings Institute; Jim Edelson, representing New Buildings Institute; Steven Rosenstock, representing Edison Electric Institute; Daniel Bresette, representing Alliance to Save Energy; Francesca Wahl, Tesla
