The University of Michigan has supported the voice of the United States education facility industry since 1993 — the second longest tenure of any voice in the United States. That voice has survived several organizational changes but remains intact and will continue its Safer-Simpler-Lower Cost-Longer Lasting advocacy on Code Panel 3 in the 2029 Edition.
Today, during our customary “Open Door” teleconference we will examine the technical concepts under the purview of Code Panel 3; among them:
Article 206 Signaling Circuits
Article 300 General Requirements for Wiring Methods and Materials
Article 590 Temporary Installations
Chapter 7 Specific Conditions for Information Technology
Chapter 9 Conductor Properties Tables
Public Input on the 2029 Edition will be received until April 9, 2026.
We examine the proposals for the 2028 National Electrical Safety Code; including our own. The 2026 National Electrical Code where sit on CMP-15 overseeing health care facility electrical issues should be released any day now. We have one proposal on the agenda of the International Code Council’s Group B Committee Action Hearings in Cleveland in October. Balloting on the next IEEE Gold Book on reliability should begin.

First Draft Proposals contain most of our proposals — and most new (original) content. We will keep the transcripts linked below but will migrate them to a new page starting 2025:
N.B. We are in the process of migrating electric power system research to the Institute of Electrical and Electronics Engineers bibliographic format.
Recap of the May meetings of the Industrial & Commercial Power Systems Conference in Las Vegas. The conference ended the day before the beginning of the 3-day Memorial Day weekend in the United States so we’re pressed for time; given all that happened.
We can use our last meeting’s agenda to refresh the status of the issues.
We typically break down our discussion into the topics listed below:
Codes & Standards:
While IAS/I&CPS has directed votes on the NEC; Mike is the only I&CPS member who is actually submitting proposals and responses to codes and standards developers to the more dominant SDO’s — International Code Council, ASHRAE International, UL, ASTM International, IEC & ISO. Mike maintains his offer to train the next generation of “code writers and vote getters”
Performance-based building premises feeder design has been proposed for the better part of ten NEC revision cycles. The objective of these proposals is to reduce material, labor and energy waste owed to the branch and feeder sizing rules that are prescriptive in Articles 210-235. Our work in service and lighting branch circuit design has been largely successful. A great deal of building interior power chain involves feeders — the network upstream from branch circuit panels but down stream from building service panel.
Our history of advocating for developing this approach, inspired by the NFPA 101 Guide to Alternative Approaches to Life Safety, and recounted in recent proposals for installing performance-based electrical feeder design into the International Building Code, appears in the link below:
Access to this draft paper for presentation at any conference that will receive it — NFPA, ICC or IEEE (or even ASHRAE) will be available for review at the link below:
NFPA 110 Definitions of Public Utility v. Merchant Utility
NFPA 72 “Definition of Dormitory Suite” and related proposals
Buildings:
Renovation economics, Smart contracts in electrical construction. UMich leadership in aluminum wiring statements in the NEC should be used to reduce wiring costs.
This paper details primary considerations in estimating the life cycle of a campus medium voltage distribution grid. Some colleges and universities are selling their entire power grid to private companies. Mike has been following these transactions but cannot do it alone.
Variable Architecture Multi-Island Microgrids
District energy:
Generator stator winding failures and implications upon insurance premiums. David Shipp and Sergio Panetta. Mike suggests more coverage of retro-fit and lapsed life cycle technicals for insurance companies setting premiums.
Reliability:
Bob Arno’s leadership in updating the Gold Book.
Mike will expand the sample set in Table 10-35, page 293 from the <75 data points in the 1975 survey to >1000 data points. Bob will set up meeting with Peyton at US Army Corps of Engineers.
Reliability of merchant utility distribution systems remains pretty much a local matter. The 2023 Edition of the NESC shows modest improvement in the vocabulary of reliability concepts. For the 2028 Edition Mike submitted several proposals to at least reference IEEE titles in the distribution reliability domain. It seems odd (at least to Mike) that the NESC committees do not even reference IEEE technical literature such as Bob’s Gold Book which has been active for decades. Mike will continue to propose changes in other standards catalogs — such as ASTM, ASHRAE and ICC — which may be more responsive to best practice assertions. Ultimately, improvements will require state public utility commission regulations — and we support increases in tariffs so that utilities can afford these improvements.
Mike needs help from IEEE Piscataway on standard WordPress theme limitations for the data collection platform.
Mike will update the campus power outage database.
Healthcare:
Giuseppe Parise’s recent work in Italian power grid to its hospitals, given its elevated earthquake risk. Mike’s review of Giuseppe’s paper:
Mike and David Shipp will prepare a position paper for the Harvard Healthcare Management Journal on reliability advantages of impedance grounding for the larger systems.
The Internet of Bodies
Forensics:
Giuseppe’s session was noteworthy for illuminating the similarity and differences between the Italian and US legal system in handling electrotechnology issues.
Mike will restock the committee’s library of lawsuits transactions.
Ports:
Giuseppe updates on the energy and security issues of international ports. Mike limits his time in this committee even though the State of Michigan has the most fresh water international ports in the world.
A PROPOSED GUIDE FOR THE ENERGY PLAN AND ELECTRICAL INFRASTRUCTURE OF A PORT
Other:
Proposals to the 2028 National Electrical Safety Code: Accepted Best Practice, exterior switchgear guarding, scope expansion into ICC and ASHRAE catalog,
Apparently both the Dot Standards and the Color Books will continue parallel development. Only the Gold Book is being updated; led by Bob Arno. Mike admitted confusion but reminded everyone that any references to IEEE best practice literature in the NFPA catalog, was installed Mike himself (who would like some backup help)
Mike assured Christel Hunter (General Cable) that his proposals for reducing the 180 VA per-outlet requirements, and the performance-base design allowance for building interior feeders do not violate the results of the Neher-McGrath calculation used for conductor sizing. All insulation and conducting material thermal limits are unaffected.
Other informal discussions centered on the rising cost of copper wiring and the implications for the global electrotechnical transformation involving the build out of quantum computing and autonomous vehicles. Few expressed optimism that government ambitions for the same could be met in any practical way.
Are students avoiding use of Chat GPT for energy conservation reasons? Mike will be breaking out this topic for a dedicated standards inquiry session:

Today we refresh our understanding of the moment in illumination technologies for outdoor lighting systems— related but different from our exploration of building interior illumination systems in Illumination 200. Later in 2024 we will roll out Illumination 400 (Holiday illumination) and Illumination 500 which explores litigation related to public illumination technology. As cities-within-cities the shared perimeter of a campus with the host municipality has proven rich in legal controversy and action.
Illumination technology was the original inspiration for the electric utility industry; providing night-time security and transforming every sector of every economy on earth. Lighting load remains the largest component of any building’s electric load — about 35 percent– making it a large target for energy regulations.
Our inquiry begins with selections from the following documents…
2023 National Electrical Code: Article 410 (While the bulk of the NEC concerns indoor wiring fire hazards, there are passages that inform outdoor lighting wiring safety)
…and about 20 other accredited, consortia or ad hoc standards developers and publishers aligned principally with vertical incumbents. Illumination was the original inspiration (i.e. the first “killer app”) for the electrical power industry in every nation. Its best practice literature reflects a fast-moving, shape-changing domain.

Outdoor lighting systems can be owned and maintained by different entities depending on the context and location. Here are some examples of ownership regimes for outdoor lighting systems:
Public ownership: In this case, outdoor lighting systems are owned and maintained by the local government or municipal authority. The lighting may be installed in public spaces such as parks, streets, and other outdoor areas for the safety and convenience of the public.
Private ownership: Outdoor lighting systems may be owned by private individuals or organizations. For example, a business owner may install outdoor lighting for security or aesthetic reasons, or a homeowner may install outdoor lighting in their garden or yard.
Co-owned: Outdoor lighting systems may be owned jointly by multiple entities. For example, a residential community may jointly own and maintain outdoor lighting in their shared spaces such as parking areas, community parks, or recreational facilities.
Utility ownership: Outdoor lighting systems may be owned and maintained by utility companies such as electric or energy companies. These companies may install and maintain street lights or other lighting systems for the public good.
Third-party ownership: In some cases, a third-party entity may own and maintain outdoor lighting systems on behalf of a public or private entity. For example, a lighting contractor may install and maintain lighting in a public park on behalf of a local government.
The ownership regime of an outdoor lighting system can have implications for issues such as installation, maintenance, and cost-sharing. It is important to consider ownership when designing and implementing outdoor lighting systems to ensure their long-term effectiveness and sustainability.

The International Commission on Illumination — is devoted to worldwide cooperation and the exchange of information on all matters relating to the science and art of light and lighting, colour and vision, photobiology and image technology. The landing page for its standards setting enterprise is linked below:
With strong technical, scientific and cultural foundations, the CIE is an independent, non-profit organization that serves member countries on a voluntary basis. Since its inception in 1913, the CIE has become a professional organization and has been accepted as representing the best authority on the subject and as such is recognized by ISO as an international standardization body.
Illumination technologies influence designs in architectural design, public safety and energy economics in all education communities. We find CIE titles referenced in ISO and IEC standards. Because ISO and IEC standards are incorporated by referenced in the best practice literature published by standards setting organizations in every nation with a private standards setting body (such as ANSI, BSI, DIN, etc.) the CIE titles are worthy of our attention.
There are others that we may track in the fullness of time. Getting illumination technology right is subtle art. The energy to drive normal, steady-state illumination usually consumes 25 to 40 percent of building energy but application of the art — which includes control — can reduce that.
We maintain CIE titles on our periodic Energy, Global, Interiors and Illumination colloquia. See our CALENDAR for the next online meeting; open to everyone.

The “Dark Ages” produced the most divine vessels of light ever built.
The purpose of the code is to establish minimum requirements to provide a reasonable level of health, safety, property protection and welfare by controlling the design, location, use or occupancy of all buildings and structures through the regulated and orderly development of land and land uses within this jurisdiction.

Municipalities usually have specific land use or zoning considerations to accommodate the unique needs and characteristics of college towns:
Mixed-Use Zoning: Cities with colleges and universities often employ mixed-use zoning strategies to encourage a vibrant and diverse urban environment. This zoning approach allows for a combination of residential, commercial, and institutional uses within the same area, fostering a sense of community and facilitating interactions between students, faculty, and residents.
Height and Density Restrictions: Due to the presence of educational institutions, cities may have specific regulations on building height and density to ensure compatibility with the surrounding neighborhoods and maintain the character of the area. These restrictions help balance the need for development with the preservation of the existing urban fabric.
Student Housing: Cities with colleges and universities may have regulations or guidelines for student housing to ensure an adequate supply of affordable and safe accommodations for students. This can include requirements for minimum bedroom sizes, occupancy limits, and proximity to campus.
Parking and Transportation: Given the concentration of students, faculty, and staff, parking and transportation considerations are crucial. Cities may require educational institutions to provide parking facilities or implement transportation demand management strategies, such as promoting public transit use, cycling infrastructure, and pedestrian-friendly designs.
Community Engagement: Some cities encourage colleges and universities to engage with the local community through formalized agreements or community benefit plans. These may include commitments to support local businesses, contribute to neighborhood improvement projects, or provide educational and cultural resources to residents.
This is a relatively new title in the International Code Council catalog; revised every three years in the Group B tranche of titles. Search on character strings such as “zoning” in the link below reveals the ideas that ran through the current revision:
Reed v. Town of Gilbert (2015): This Supreme Court case involved a challenge to the town of Gilbert, Arizona’s sign code, which regulated the size, location, and duration of signs based on their content. The court held that the sign code was a content-based restriction on speech and therefore subject to strict scrutiny.
City of Ladue v. Gilleo (1994): In this Supreme Court case, the court struck down a municipal ordinance that banned the display of signs on residential property, except for signs that fell within specific exemptions. The court held that the ban was an unconstitutional restriction on the freedom of speech.
Metromedia, Inc. v. San Diego (1981): This Supreme Court case involved a challenge to a San Diego ordinance that banned off-premises advertising signs while allowing on-premises signs. The court held that the ordinance was an unconstitutional restriction on free speech, as it discriminated against certain types of speech.
City of Ladue v. Center for the Study of Responsive Law, Inc. (1980): In this Supreme Court case, the court upheld a municipal ordinance that prohibited the display of signs on public property, but only if the signs were posted for longer than 10 days. The court held that the ordinance was a valid time, place, and manner restriction on speech.
City of Boerne v. Flores (1997): This Supreme Court case involved a challenge to a municipal sign code that regulated the size, location, and content of signs in the city. The court held that the sign code violated the Religious Freedom Restoration Act, as it burdened the exercise of religion without a compelling government interest.
Best wiring safety practice for the illumination of educational settlement occupancies is scattered throughout the National Electrical Code with primary consideration for wiring fire safety:
Article 410 – Covers the installation of luminaires (fixtures), lampholders, and lamps, including requirements for wiring, grounding, and support.
The renovated Schwarzman Center at Yale now features dynamic new communal areas, a refreshed historic dining hall and eye-catching exterior lighting, enhancing the campus experience.
* Approximate Order of Magnitude Estimates: International student fees account for approximately 25–27% of total Australian university revenue. In 2024, this equated to A$12.33 billion out of A$45.17 billion in gross revenue across 42 universities. The vast majority of these international students come from Asia (particularly China, India, Nepal, Vietnam, and other nearby countries), which consistently represent over 90% of international enrolments in higher education. Sources indicate most are from Asian countries, with top sources alone (China ~23%, India ~17%, Nepal ~8%, etc.) comprising well over half, and historical figures showing ~80–90% from Asia overall.
