Electric vehicle charging stations are addressed in the 2024 International Energy Conservation Code (IECC) within two specific appendices:
Appendix RE: This appendix provides detailed requirements for electric vehicle charging infrastructure, focusing on both residential and commercial buildings. It includes definitions and infrastructure standards to ensure that new constructions are equipped to support electric vehicle charging
Appendix CG: This appendix offers guidance on electric vehicle power transfer and charging infrastructure, emphasizing the integration of EV-ready requirements into building designs. It outlines the necessary provisions for installing and managing EV charging stations, ensuring compliance with energy conservation standards
.These appendices are part of the broader efforts to incorporate EV infrastructure into building codes, promoting energy efficiency and supporting the transition to electric vehicles.

Keep in mind that many electric vehicle safety and sustainability concepts will track in other titles in the ICC catalog. It is enlightening to see other energy related proposals tracking in the most recent Group A code revision cycle
The following proposals discussed during the Group A Hearings ended earlier this month are noteworthy:
IBC § 202 (NEW) | G66-21 | Electrical mobility definitions
IBC § 1107.2, et al | E124-21 & E125-21 & E126-21 | Electrical vehicle charging stations for R-2 occupancies.
From the Group B revision cycle — COMPLETE MONOGRAPH:
R309.6 Electric vehicle charging stations and systems. Where provided, electric vehicle charging systems shall be installed in accordance with NFPA 70.

Incumbents are socking in EV concepts all across the ICC catalog. We refer them to experts in the Industrial Applications Society IEEE E&H Committee.
One of the more spirited debates in recent revision cycles is the following:
Who shall pay for electrical vehicle charging infrastructure?
The underlying assumption is that the electrification of the global transportation grid has a net benefit. We remain mute on that question; the question of net gain.
Of course, many proposals pointed the finger at the stakeholder with the deepest pockets. Accordingly, new commercial building owners will be required to install charging stations for new buildings. During 2018 and 2019 we tracked the action in the workspace below so that we could collaborate with the IEEE Education & Healthcare Facilities Committee:
2021 Electric Vehicle Infrastructure
Given that most higher education facilities are classified as commercial, the cost of charging stations will be conveyed into the new building construction budget unless the unit takes an exception. Generally speaking, most colleges and universities like to display their electric vehicle credentials, even if the use of such charging stations remains sparse.

Stochastic hybrid models for predicting the behavior of drivers facing the yellow-light-dilemma
Paul A. Green | University of Michigan
Daniel Hoehener & Domitilla Del Vecchio | Massachusetts Institute of Technology
Abstract: We address the problem of predicting whether a driver facing the yellow-light-dilemma will cross the intersection with the red light. Based on driving simulator data, we propose a stochastic hybrid system model for driver behavior. Using this model combined with Gaussian process estimation and Monte Carlo simulations, we obtain an upper bound for the probability of crossing with the red light. This upper bound has a prescribed confidence level and can be calculated quickly on-line in a recursive fashion as more data become available. Calculating also a lower bound we can show that the upper bound is on average less than 3% higher than the true probability. Moreover, tests on driving simulator data show that 99% of the actual red light violations, are predicted to cross on red with probability greater than 0.95 while less than 5% of the compliant trajectories are predicted to have an equally high probability of crossing. Determining the probability of crossing with the red light will be important for the development of warning systems that prevent red light violations.

Easter Bread & Yaupon Tea
“Every year as Easter approaches, if you are lucky, you might catch the scent of baking bread and fragrant anise wafting in the air in my hometown of Clarksburg, West Virginia. Easter bread, sweet and flavored with anise seed, is a holiday ritual in the Italian-American community here. With roots stretching back to Calabria, making Easter bread is a foodways tradition that now thrives in North Central West Virginia” — Lori Hostuttler, Assistant Director at West Virginia & Regional History Center

Yaupon Drink: A Medicine Bundle in the Atlantic World
Steven P. Carriger Jr, University of Tennessee, Knoxville
Abstract. This dissertation examines yaupon drink, a tea made from yaupon holly along with other ingredients, as a medicine bundle in the Atlantic World. Originally a medicinal drink used by Native Americans across the what is today the American South, over time the tea became a trade good demanded by the Spanish and a medicinal herb sought by European botanists and medical practitioners. Chapter One traces yaupon’s origins across the southeast and bundles the drink into the many cosmic and social connections it held. Chapter Two shows how the Spanish colonial presence offered an alternative to yaupon in Florida, through Christianity and its Sacraments even as the Spanish themselves began to commodify it, demanding it as an item of tribute. Chapter Three looks beyond Spanish Florida into the interior of the southeast as Creek, Cherokee, and Natchez towns negotiated the “Shatter Zone” and shows how towns of the Native Americans preserved or changed how they used yaupon in response to European colonialism. Chapter Four explains how the yaupon became a part of medicine and gardens in early modern Europe and how its leaves negotiated the changes that the Enlightenment brought. Using archaeology and European narrative histories, this dissertation examines yaupon drink within its relational fields, recognizing its affordances and how these help write a small piece of a decolonized history of the tangled relationships among Native Americans and Europeans in Southeast and the larger Atlantic World.
