Electric Vehicle Charging

GROUP A MODEL BUILDING CODES: Comments on Committee Actions will be received until July 8th

International Building Code Chapter 4, Section 406.2.7

Edison electric vehicle | National Park Service, US Department of the Interior

 

Free public access to the 2021 edition of the International Energy Conservation Code (IECC) is linked below:

2021 International Energy Conservation Code

 

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.

This standard will be updated within a reconfigured code development cycle linked below:

2024/2025/2026 ICC CODE DEVELOPMENT SCHEDULE

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.

2025 Committee Action Hearings – Group B #1

Proposal for Performance-Based Building Premise Wiring | Chapter 27): Monograph Page 754

Electrical building — World Columbian Exposition, Chicago, Illinois 1892

The International Code Council bibliography of electrical safety practice incorporates titles published by the National Fire Protection Association which reference electrical safety science titles published by the Institute of Electrical and Electronic Engineers.  The relevant section of the International Building Code is therefore relatively short:

2021 International Building Code: Chapter 27 Electrical

Note that Chapter 27 provides more guidance on managing the hazards created when electricity is absent*.  Since the National Electrical Code is informed by a fire safety building premise wiring culture; absence of electricity is not as great a hazard as when building wiring systems are energized.  (“So they say” — Mike Anthony, who thinks quite otherwise.)

2025 GROUP B PROPOSED CHANGES TO THE I-CODES | Complete Monograph (2630 pages)

Although we collaborate most closely with the IEEE Education & Healthcare Facilities Committee (four times monthly in Europe and the Americas) we e encourage our colleagues in education communities everywhere to participate directly in the ICC Code Development process.   CLICK HERE to set up an account.

It is enlightening — and a time saver — to unpack the transcripts of previous revisions of codes and standards to see what concepts were presented, what got discussed; what passed and what failed.  We provide links to a few previous posts that track recent action in the ICC suite relevant to electrotechnologies:

Electric Vehicle Charging

Entertainment Occupancies

K-TAG Matrix for Healthcare Facilities

The ICC suite of consensus products are relevant to almost all of our work; everyday.   See our CALENDAR that reflects our Syllabus.  Today we deal with electrical safety concepts because technical committees are meeting from November to January to write the 2023 National Electrical Code.  CLICK HERE to follow the action in more detail.

* The original University of Michigan advocacy enterprise began pounding on National Electrical Code committees to install more power reliability concepts in the 2002 Edition with only modest success.  Standards Michigan has since collaborated with the IEEE Education & Healthcare Facilities Committee to drive “absence-of-power-as-a-hazard” into the National Electrical Code; the 2023 now open for public consultation.

N.B.

Assuming building interior fire safety issues can be managed, one way of getting more electric vehicle charging stations built around campus is to install requirements into the building code — thereby putting the construction cost, operation, maintenance and risk upon real-asset Developers and Owners. Code change submittals for the Group A tranche of titles will be received until January 8, 2024.

 

Places of Worship

“The Church is not a gallery for the exhibition of eminent Christians,

but a school for the education of imperfect ones.”

— Henry Ward Beecher

WEBCAST Committee Action Hearings, Group A #2

 

2024 International Building Code: Chapter 3 Occupancy Classification and Use

In the International Code Council catalog of best practice literature we find the first principles for safety in places of worship tracking in the following sections of the International Building Code (IBC):

Section 303 Assembly Group A

“303.1.4:  Accessory religious educational rooms and religious auditoriums with occupant loads less than 100 per room or space are not considered separate occupancies.”   This informs how fire protection systems are designed.

Section 305 Educational Group E

“305.2.1: Rooms and spaces within places of worship proving such day care during religious functions shall be classified as part of the primary occupancy.”  This group includes building and structures or portions thereof occupied by more than five children older than 2-1/2 years of age who receive educational, supervision or personal care services for fewer than 24 hours per day.

Section 308 Institutional Group I

“308.5.2: Rooms and spaces within places of religious worship providing [Group I-4 Day Care Facilities] during religious functions shall be classified as part of the primary occupancy.   When [Group I-4 Day Care Facilities] includes buildings and structures occupied by more than five persons of any age who receive custodial care for fewer than 24 hours per day by persons other than parents or guardians, relatives by blood, marriage or adoption, and in a place other than the home of the person cared for.

Tricky stuff — and we haven’t even included conditions under which university-affiliated places of worship may expected to be used as community storm shelters.

"This We'll Defend."

2024/2025/2026 ICC CODE DEVELOPMENT SCHEDULE

Public response to Committee Actions taken in Orlando in April will be received until July 8th.

Because standard development tends to be a backward-looking domain it is enlightening to understand the concepts in play in previous editions.  The complete monograph of proposals for new building safety concepts for places of worship for the current revision cycle is linked below:

 2021/2022 Code Development: Group B

A simple search on the word “worship” will reveal what ideas are in play.  With the Group B Public Comment Hearings now complete ICC administered committees are now curating the results for the Online Governmental Consensus Vote milestone in the ICC process that was completed December 6th.   Status reports are linked below:

2018/2019 Code Development: Group B

Note that a number of proposals that passed the governmental vote are being challenged by a number of stakeholders in a follow-on appeals process:

2019 Group B Appeals

A quick review of the appeals statements reveals some concern over process, administration and technical matters but none of them directly affect how leading practice for places of worship is asserted.

We are happy to get down in the weeds with facility professionals on other technical issues regarding other occupancy classes that are present in educational communities.   See our CALENDAR for next Construction (Ædificare) colloquium open to everyone.

Building Structural Maintenance

φ
Any multi-story building requires inspection and maintenance of structural steel framework. The steel supports the building’s weight and resists environmental forces like wind and seismic activity. Over time, corrosion, fatigue cracks, or connection failures can weaken the structure, risking collapse. Inspections detect these issues early, while maintenance, like repainting or replacing damaged parts, preserves steel integrity. For student housing, occupant safety is critical, and compliance with building codes reduces liability risks. Neglecting these practices can lead to structural failure, endangering residents and causing costly repairs or legal issues. Regular upkeep ensures safe, long-lasting buildings.
During today’s session we examine the relevant standards with proposed revisions open for public comment.  Use the login credentials at the upper right of our home page.
φ
No single universal code or standard guarantees that buildings will never crack or fail structurally, as structural integrity depends on various factors like design, materials, construction quality, environmental conditions, and maintenance. However, several widely adopted codes and standards aim to minimize the risk of structural failure and ensure safety, durability, and serviceability. These provide guidelines for design, construction, and maintenance to prevent issues like cracking or catastrophic failure.
φ

Key Codes and Standards:

International Building Code (IBC): Widely used in the United States and other regions, the IBC sets minimum requirements for structural design, materials, and maintenance to ensure safety and performance.  It references standards like ASCE 7 (Minimum Design Loads and Associated Criteria for Buildings and Other Structures) for load calculations (e.g., wind, seismic, snow).Maintenance provisions require regular inspections and repairs to address issues like cracking or deterioration.

ACI 318 (Building Code Requirements for Structural Concrete): Published by the American Concrete Institute this standard governs the design and construction of concrete structures.Includes requirements to control cracking (e.g., reinforcement detailing, concrete mix design) and ensure durability under environmental exposure.Maintenance guidelines recommend periodic inspections for cracks, spalling, or reinforcement corrosion.

AISC 360 (Specification for Structural Steel Buildings): Published by the American Institute of Steel Construction, this standard covers the design, fabrication, and erection of steel structures.  Addresses fatigue, connection design, and corrosion protection to prevent structural failure. Maintenance involves inspecting for issues like weld imperfections or coating degradation.

ASCE/SEI 41-17 (Seismic Evaluation and Retrofit of Existing Buildings):  Focuses on assessing and maintaining existing structures, particularly for seismic performance.  Guides retrofitting to address vulnerabilities like cracking or inadequate load paths.
Maintenance Standards
  • ACI 562 (Assessment, Repair, and Rehabilitation of Existing Concrete Structures):
    • Provides a framework for evaluating and repairing concrete structures to address cracking, spalling, or other damage.
    • Emphasizes regular inspections and timely repairs to maintain structural integrity.
  • NACE/SP0108 (Corrosion Control of Offshore Structures):
    • Covers maintenance practices to prevent corrosion-related failures in steel structures.
  • ASTM E2270 (Standard Practice for Periodic Inspection of Building Facades):
    • Outlines procedures for inspecting facades to identify cracking, water infiltration, or other issues that could lead to structural problems.

Shouldn’t energy conservation measures be determined by market forces rather than building construction regulations? 

Energy codes in the United States are adopted and enforced at the state level, and the stringency of the energy codes can vary widely from state to state.  For example, as of September 2021, four states (Alabama, Mississippi, South Carolina, and West Virginia) had not adopted statewide energy codes at all, according to the Building Codes Assistance Project. Other states may have adopted energy codes but have not updated them to the latest version, which could be less stringent than more recent versions.

We do not spend too many resources challenging the zietgeist.  Engineers, by nature, seek to do more with less but it is worth reminding our colleagues that energy conservation practices vary widely around the globe and not every nation supports what amounts to an energy police state.

Apart from product prescriptive passages IECC is a largely a performance code which draws its inspiration from other energy-related catalogs developed by United States standards developers; notably ASHRAE International.  Several accessory titles supporting the current 2021 edition which address energy efficiency on several fronts including cost, energy usage, use of natural resources and the impact of energy usage on the environment are linked below:

Note the pre-occupation with products such as insulation, fenestration, power outlets and lighting — reflecting the financial support of energy activists advocating on behalf of manufacturers who tend build the cost of their advocacy in the price of their product.

A commonly overlooked energy conservation measure is reducing standby power consumption, also known as “vampire power.” Many electronic devices, such as televisions, computers, and chargers, consume energy even when they are not actively being used but are still plugged in. This standby power can account for up to 10% of a building’s energy consumption.

While our focus tends to be on the commercial facility docket, we keep an eye on the residential docket because, a)  many colleges and universities own and operate square-footage on the periphery of their campuses that is classified as residential, b) many student rental houses are obviously classified as residential and we want property owners to be able to afford reasonable energy conservation measures for the houses they rent to students.*

From previous posts we explained we summarized our priorities for the Group B cycle and the IECC in particular:

  • Education facilities as storm shelters
  • Laboratory ventilation
  • Classroom lighting
  • Expansion of lighting controls
  • Expansion of receptacle controls
  • Expansion of electrical power system design requirements above beyond National Electrical Code minimums.

We encourage our colleagues in energy enterprises in education communities to participate directly in the ICC Code Development Process.*

2024 GROUP A PROPOSED CHANGES TO THE I-CODES: Complete Monograph (2658 pages)

Commercial kitchens offer several benefits, such as efficient food preparation and large-scale production, allowing businesses to meet high demand. They provide professional-grade equipment and ample space, enabling chefs to explore culinary creativity. Commercial kitchens also promote hygiene and food safety standards, with dedicated cleaning protocols and inspections. However, hazards can arise from the high-temperature cooking equipment, sharp tools, and potentially hazardous substances. There is also a risk of burns, slips, and falls, emphasizing the importance of proper training and safety measures. Adequate ventilation and fire safety systems are vital to prevent accidents and maintain a healthy working environment.

The International Code Council is re-configuring its code development process in nearly every dimension. While that situation stabilizes let us review the back-and-forth on this topic during the previous revision cycle (linked below):

2021 International Building Code Section 306 Factory Group F Moderate Hazard

2021 International Fire Code Section 606 Commercial Cooking Equipment and Systems

The International Code Council has recently re-configured its code development calendar:

2024/2025/2026 ICC CODE DEVELOPMENT SCHEDULE

Public hearings on the proposed changes happen in Orlando, April 7-16.

This is a summary of the actions taken on the 2024 Comments on Proposed Changes to the ICC International Codes at the October 23-28, 2024 Committee Action Hearings #2 held at the Long Beach Convention Center, Long Beach, California.  Balloting of local building code officials is now underway.

 

Commercial kitchen electrical power wiring requirements are covered extensively in Article 210 through Article 215 of the National Electrical Code.  Standards action in this domain is referred to IEEE Education & Healthcare Facility Committee.
