“…O chestnut tree;, great rooted blossomer,
Are you the leaf, the blossom or the bold?
O body swayed to music, O brightening glance,
How can we know the dancer from the dance?”

Among Schoolchildren, 1933 William Butler Yeats

We sweep through the world’s three major time zones; updating our understanding of the literature at the technical foundation of education community safety and sustainability in those time zones 24 times per day. We generally eschew “over-coding” web pages to sustain speed, revision cadence and richness of content as peak priority.  We do not provide a search facility because of copyrights of publishers and time sensitivity of almost everything we do.

Our daily colloquia are typically doing sessions; with non-USA titles receiving priority until 16:00 UTC and all other titles thereafter.  We assume policy objectives are established (Safer-Simpler-Lower-Cost, Longer-Lasting).   Because we necessarily get into the weeds, and because much of the content is time-sensitive and copyright protected, we usually schedule a separate time slot to hammer on technical specifics so that our response to consultations are meaningful and contribute to the goals of the standards developing organization and to the goals of stewards of education community real assets — typically the largest real asset owned by any US state and about 50 percent of its annual budget.

1. Leviathan.  We track noteworthy legislative proposals in the United States 118th Congress.  Not many deal specifically with education community real assets since the relevant legislation is already under administrative control of various Executive Branch Departments such as the Department of Education.

We do not advocate in legislative activity at any level.   We respond to public consultations but there it ends.

We track federal legislative action because it provides a stroboscopic view of the moment — the “national conversation”– in communities that are simultaneously a business and a culture.  Even though more than 90 percent of such proposals are at the mercy of the party leadership the process does enlighten the strengths and weakness of a governance system run entirely through the counties on the periphery of Washington D.C.  It is impossible to solve technical problems in facilities without sensitivity to the zietgeist that has accelerated in education communities everywhere.

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.

IEEE E&H Draft Agenda 28 May 2024

On site conference agenda:

IEEE E&H Conference Agenda 21 May 2024

NESC & NEC Cross-Code Correlation

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:

Toward Performance-Based Building Premise Feeder Design

Buildings:

Renovation economics, Smart contracts in electrical construction.  UMich leadership in aluminum wiring statements in the NEC should be used to reduce wiring costs.

Copper can’t be mined fast enough to electrify the United States

Daleep asked Mike to do a Case Study session on the NEC lighting power density change (NEC 220-14) for the IAS Annual Meeting in October.  Mike agreed.

Exterior Campus & Distribution:

Illumination.  Gary Fox reported that IEEE 3001.9 was endorsed as an ANSI accredited standard for illumination systems.

2024-ICPSD24-0012 PERMANENT DESIGN OF POWER SYSTEMS Parise

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:

Harvard Business School: Journal of Healthcare Management Standards

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)

Universities with Quantum Computing Facilities

Papers in Process:

Impedance Grounding Papers 1 and 2 with David Shipp.  Previous Discussion:

https://ieeetv.ieee.org/channels/ieee-region-events/uc-berkeley-s-medium-voltage-grounding-system

Over Coffee and Beers:

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:

When the wicked problems of peace and economic inequality cannot be solved, political leaders, and the battalions of servile administrative muckety-mucks who report to them, resort to fear-mongering about an imagined problem to be solved centuries hence assuming every other nation agrees on remedies of its anthropogenic origin.  We would not draw attention to it were it not that large tranches of the global academic community are in on the grift costing hundreds of billions in square-footage for research and teaching hopelessness to our children and hatred of climate change deniers.

The Business of Standards Never Stops

Standards for a Kitchen Symphony | November/December 2024

ASTM International (formerly known as the American Society for Testing and Materials) is a globally recognized organization that develops and publishes technical standards for a wide range of products, systems, and services. These standards are used by manufacturers, regulatory bodies, and other stakeholders to ensure that products and services are safe, reliable, and of high quality.

In the field of measurement science, ASTM plays an important role in developing standards and guidelines for measurement techniques and practices. These standards cover a wide range of topics related to measurement science, including the calibration of instruments, the characterization of measurement systems, and the validation of measurement results. They are used by researchers, engineers, and other professionals in academia, industry, and government to ensure that measurements are accurate, precise, and reliable.

ANSI Public Review

 

ASTM standards for measurement science are developed through a process that involves input from experts in the field, including researchers, industry professionals, and regulatory bodies. These standards are updated regularly to reflect advances in measurement science and technology, as well as changes in industry and regulatory requirements.  This is a far better way to discover and promulgate leading practice.  In fact, there are regulations intended to restrain the outsized influence of vertical incumbents in legislative precincts where market-making happens.

2025 National Patent Application Drafting Competition

 

Thomas Jefferson was the leader in founding the United States Patent Office. Jefferson was a strong supporter of the patent system and believed that it was essential for promoting innovation and progress in the United States. As the first Secretary of State Jefferson was responsible for implementing the country’s patent system.

Article I, Section 8, Clause 8 of the United States Constitution reads as follows:

“The Congress shall have Power To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries.”

In 1790, Jefferson drafted the first Patent Act, which established the procedures for applying for and granting patents. The act also created the United States Patent Office as a government agency to oversee the patent system. Jefferson appointed the first Patent Board, which was responsible for reviewing patent applications and making recommendations to the Secretary of State.

Jefferson was deeply involved in the early development of the Patent Office and was instrumental in shaping its policies and procedures. He believed that the patent system should be accessible to all inventors, regardless of their social or economic status, and he worked to streamline the patent application process to make it more efficient and user-friendly.

In recognition of his contributions to the development of the patent system, Jefferson is often referred to as the “Father of American Innovation.”

This clause grants Congress the authority to establish a system of patents and copyrights to protect the intellectual property of inventors and authors. The purpose of this system is to encourage innovation and creativity by providing inventors and authors with a temporary monopoly on their creations, allowing them to profit from their work and invest in future projects. The clause also emphasizes the importance of promoting the progress of science and the useful arts, reflecting the belief of the founders that the development of new technologies and inventions was essential for the growth and prosperity of the United States.

Over the years, the Patent Office has played a crucial role in the development of the United States as a technological leader, granting patents for inventions ranging from the telephone and the light bulb to the airplane and the computer. Today, the Patent Office is part of the United States Department of Commerce and is responsible for examining patent applications and issuing patents to inventors and companies.

Python can be used to control building automation systems. Building automation systems are typically used to control various systems within a building, such as heating, ventilation, air conditioning, lighting, security, and more. Python can be used to control these systems by interacting with the control systems through the building’s network or other interfaces.

There are several Python libraries available that can be used for building automation, including PyVISA, which is used to communicate with instrumentation and control systems, and PyModbus, which is used to communicate with Modbus devices commonly used in building automation systems. Python can also be used to develop custom applications and scripts to automate building systems, such as scheduling temperature setpoints, turning on and off lights, and adjusting ventilation systems based on occupancy or other variables. Overall, Python’s flexibility and versatility make it well-suited for use in building automation systems.

How Consistent Are the Best-Known Readability Equations in Estimating the Readability of Design Standards?

Abstract.  Research problem: Readability equations are widely used to compute how well readers will be able to understand written materials. Those equations were usually developed for nontechnical materials, namely, textbooks for elementary, middle, and high schools. This study examines to what extent computerized readability predictions are consistent for highly technical material – selected Society of Automotive Engineers (SAE) and International Standards Organization (ISO) Recommended Practices and Standards relating to driver interfaces. Literature review: A review of original sources of readability equations revealed a lack of specific criteria in counting various punctuation and text elements, leading to inconsistent readability scores. Few studies on the reliability of readability equations have identified this problem, and even fewer have systematically investigated the extent of the problem and the reasons why it occurs.  Research questions:

(1) Do the most commonly used equations give identical readability scores?
(2) How do the scores for each readability equation vary with readability tools?
(3) If there are differences between readability tools, why do they occur?
(4) How does the score vary with the length of passage examined?

Method: Passages of varying lengths from 12 selected SAE and ISO Recommended Practices and Standards were examined using five readability equations (Flesch-Kincaid Grade Level, Gunning Fog Index, SMOG Index, Coleman-Liau Index, and Automated Readability Index) implemented five ways (four online readability tools and Microsoft Word 2013 for Windows). In addition, short test passages of text were used to understand how different readability tools counted text elements, such as words and sentences. Results and conclusions: The mean readability scores of the passages from those 12 SAE and ISO Recommended Practices and Standards ranged from the 10th grade reading level to about 15th. The mean grade reading levels computed across the websites were: Flesch-Kincaid 12.8, Gunning Fog 15.1 SMOG 12.6, Coleman-Liau 13.7, and Automated Readability Index 12.3. Readability score estimates became more consistent as the length of the passage examined increased, with no noteworthy improvements beyond 900 words. Among the five readability tools, scores typically differed by two grade levels, but the scores should have been the same. These differences were due to how compound and hyphenated words, slashes, numbers, abbreviations and acronyms, and URLs were counted, as well other punctuation and text elements. These differences occurred because the sources for these equations often did not specify how to score various punctuation and text elements. Of the tools examined, the authors recommend Microsoft Word 2013 for Windows if the Flesch-Kincaid Grade Level is required.

Metrology is the scientific discipline that deals with measurement, including both the theoretical and practical aspects of measurement. It is a broad field that encompasses many different areas, including length, mass, time, temperature, and electrical and optical measurements.  The goal of metrology is to establish a system of measurement that is accurate, reliable, and consistent. This involves the development of standards and calibration methods that enable precise and traceable measurements to be made.

The International System of Units is the most widely used system of units today and is based on a set of seven base units, which are defined in terms of physical constants or other fundamental quantities.  Another important aspect of metrology is the development and use of measurement instruments and techniques. These instruments and techniques must be designed to minimize errors and uncertainties in measurements, and they must be calibrated against recognized standards to ensure accuracy and traceability.

Metrology also involves the development of statistical methods for analyzing and interpreting measurement data. These methods are used to quantify the uncertainty associated with measurement results and to determine the reliability of those results.
