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. Electric vehicle charging system equipment shall be listed and labeled in accordance with UL 2202. Electric vehicle supply equipment shall be listed and labeled in accordance with UL 2594.
IBC 406.2.7 Electric vehicle charging stations and systems. Where provided, electric vehicle charging systems shall be installed in accordance with NFPA 70. Electric vehicle charging system equipment shall be listed and labeled in accordance with UL 2202. Electric vehicle supply equipment shall be listed and labeled in accordance with UL 2594. Accessibility to electric vehicle charging stations shall be provided in accordance with Section 1108.

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.

The 2020 National Electrical Code (NEC) contains significant revisions to Article 625 Electric Vehicle Power Transfer Systems. Free access to this information is linked below:
You will need to set up a (free) account to view Article 625 or you may join our colloquium today.
Public input for the 2023 Edition of the NEC has already been received. The work of the assigned committee — Code Making Panel 12 — is linked below:
NFPA 70_A2022_NEC_P12_FD_PIReport_rev
Mighty spirited debate. Wireless charging from in-ground facilities employing magnetic resonance are noteworthy.
Technical committees meet November – January to respond. In the intervening time it is helpful break down the ideas that were in play last cycle. The links below provide the access point:
Public Comment Report Panel 12
We find a fair amount of administrative and harmonization action; fairly common in any revision cycle. We have taken an interest in a few specific concepts that track in academic research construction industry literature:
As a wiring safety installation code — with a large installer and inspection constituency — the NEC is usually the starting point for designing the power chain to electric vehicles. There is close coupling between the NEC and product conformance organizations identified by NIST as Nationally Recognized Testing Laboratories; the subject of a separate post.
After the First Draft is released June 28th public comment is receivable until August 19th.
We typically do not duplicate the work of the 10’s of thousands of National Electrical Code instructors who will be fanning out across the nation to host training sessions for electrical professionals whose license requires mandatory continuing education. That space has been a crowded space for decades. Instead we co-host “transcript reading” sessions with the IEEE Education & Healthcare Facilities Committee to sort through specifics of the 2020 NEC and to develop some of the ideas that ran through 2020 proposals but did not make it to final ballot and which we are likely to see on the docket of the 2023 NEC revision. That committee meets online 4 times monthly. We also include Article 625 on the standing agenda of our Mobility colloquium; open to everyone. See our CALENDAR for the next online meeting

U.S. NATIONAL ELECTRIC VEHICLE SAFETY STANDARDS SUMMIT | DETROIT, MICHIGAN 2010
The New York University Paulson Center 181 Mercer dormitory is a state-of-the-art residence hall located in the heart of Manhattan’s SoHo neighborhood. The building was designed by COOKFOX architects and completed in 2020.
The Paulson 181 Mercer dormitory is a 23-story building that houses more than 700 students in a mix of singles, doubles, triples, and quads. The building features a number of amenities designed to enhance the student living experience, including a fitness center, music practice rooms, a game room, and a rooftop terrace with stunning views of the city.
One of the most unique features of the Paulson 181 Mercer dormitory is its focus on sustainability and green design. The building is expected to achieve LEED Gold certification, which recognizes buildings that are designed and constructed to minimize their environmental impact. Some of the sustainable features of the building include a green roof, rainwater harvesting system, and energy-efficient lighting and HVAC systems.
The $1.2 billion John A. Paulson Center — which opened in January 2023 — provides all of the occupancy classes for the “university without a quad”.
*In 2005, Paulson began investing heavily in credit default swaps, which are essentially insurance contracts that pay out if a particular debt instrument defaults. He used these swaps to bet against the subprime mortgage market, which he believed was overvalued and ripe for collapse. When the housing market crashed in 2008, Paulson’s bets paid off in a big way, earning him billions of dollars in profits.
Paulson has also been involved in other successful trades, including investments in gold and banking stocks. However, his bet against the subprime mortgage market remains his most famous and lucrative trade.
Today we break down public consultation notices for literature that sets the standard of care for the safety and sustainability of student housing in K-12 prep schools, colleges and universities. We deal with off-campus housing in a separate session because it involves local safety and sustainability regulations; most of which are derived from residential housing codes and standards.
The topic cuts across many disciplines and standards setting organization bibliographies. We usually set our bearing with the following titles:
2021 International Building Code: Section 310 Residential Group R-2 + related titles such as the IFC, IMC, IPC, IECC
2021 Fire Code: Chapter 6 Classification of Occupancy + related titles such as NFPA 70B, NFPA 72 and NFPA 110
2023 National Electrical Code: Articles 210-230 + related Articles 110 and 410
ASHRAE 90.1 Energy Standard for Buildings Except Low-Rise Residential Buildings: Annex G
Like any other classification of real property the average cost for room and board for a public university student dormitory depends on several factors such as the location of the university, the type of dormitory, and the meal plan options. According to the College Board, the average cost of room and board for the 2021-2022 academic year at a public four-year in-state institution was $11,620. However, this figure can range from around $7,000 to $16,000 or more depending on the specific institution and its location. It’s important to note that this average cost only includes the basic meal plan and standard dormitory room. Students may also have additional costs for a larger or more luxurious dorm room, a premium meal plan, or other expenses such as laundry or parking fees.
According to ring Rider Levett Bucknall, a global property and construction consultancy firm, the average construction cost for a student housing facility in the United States in 2021 was around $202 per square foot. However, this figure can range from around $150 to $300 per square foot or more depending on the specific project. Life cycle cost for new facilities with tricked out net-zero gadgets is hard to come by at the moment.
Because money flows freely through this domain we examine scalable densities and the nature of money flow patterns; partially tracked by the Electronic Municipal Market Access always on the standing agenda of our Finance colloquium.

Report on Comments for the 2024 Uniform Plumbing Code
This paper introduced the concept of reliability theory and established a mathematical framework for analyzing system reliability in terms of lumped parameters. It defined important concepts such as coherent systems, minimal cut sets, and minimal path sets, which are still widely used in reliability engineering.
IEEE Recommended Practice for the Design of Reliable Industrial and Commercial Power Systems
“Railroad Sunset” | Edward HopperWe are tooling up to update the failure rate tables of IEEE 493 Design of Reliable Industrial and Commercial Power Systems; collaborating with project leaders but contributing to an essential part of the data design engineers use for scaling their power system designs. The project is in its early stages. We are formulating approaches about how to gather data for assemble a statistically significant data set.
Today we introduce the project which will require harvesting power reliability statistics from any and all educational settlements willing to share their data. As the links before demonstrate, we have worked in this domain for many years.
