Commercial kitchens in school cafeterias and college dormitories are designed to meet strict health and safety standards, accommodate high-volume food production, and provide nutritious meals to students in an efficient and organized manner. Some common features:
Industrial-grade cooking equipment: This may include commercial ovens, grills, ranges, fryers, steamers, and other specialized cooking equipment designed for high-volume cooking.
Food preparation areas: These may include spacious prep tables, cutting boards, sinks, and other food preparation stations for washing, chopping, and assembling ingredients.
Walk-in refrigerators and freezers: These are used for storing large quantities of perishable food items at appropriate temperatures to maintain freshness and safety.
Food storage facilities: These may include shelves, racks, and cabinets for storing dry goods, canned goods, and other non-perishable food items.
Dishwashing area: This may include commercial dishwashers capable of handling a large number of dishes and utensils efficiently.
Serving stations: These may include counters, warming stations, and other facilities for serving food to students.
Ventilation and exhaust systems: These are essential for maintaining a clean and safe kitchen environment by properly removing smoke, steam, and odors generated during cooking.
Safety features: These may include fire suppression systems, emergency exits, and other safety measures to ensure compliance with local health and safety regulations.
Owing to the complexity of the domain, starting 2023 we will break down the standards for education community safety and sustainability into two separate colloquia:
Kitchens 100 will deal primarily safety — fire, shock hazard, sanitation, floors, etc.
Kitchens 300 will deal with sustainability criteria in large commercial kitchens common in school cafeterias, dormitories, sports venues and hospitals.

One of the concentrated risk aggregations in any school district, college, university and technical school, athletic venues and university-affiliated healthcare systems, rests in the food preparation units. On a typical large research university there are hundreds of kitchens in dormitories, student unions, athletic venues, hospitals and — to a surprising degree — kitchen facilities are showing up in classroom buildings. Kitchens that used to be located on the periphery of campus and run by private industry are now moving into instructional spaces and operated by private food service vendors.
Food preparation facilities present safety challenges that are on the same scale as district energy plants, athletic concession units, media production facilities and hospital operating rooms. There are 20 accredited standards setting organizations administering leading practice discovery in this space. Some of them concerned with fire safety; others concerned with energy conservation in kitchens, still others concerned with sanitation. The International Kitchen Exhaust Cleaning Association is one of the first names in this space and maintains an accessible standards development home page; linked below:
The IKECA catalog of titles establish a standard of care for cleaning activity that fills gaps in related ASHRAE, ASME, ICC and NFPA titles. For example:
IKECA I10 Standard for the Methodology for Inspection of Commercial Kitchen Exhaust Systems
IKECA C10 Standard for the Methodology for Cleaning Commercial Kitchen Exhaust Systems
We encourage subject matter experts in food enterprises in the education industry to communicate directly with John Dixon at IKCEA (jdixon@fernley.com) or Elizabeth Franks, (215) 320-3876, information@ikeca.org, International Kitchen Exhaust Cleaning Association, 100 North 20th Street, Suite 400, Philadelphia, PA 19103.
We are happy to get specific about how the IKECA suite contributes to lower education community cost during our Food teleconferences. See our CALENDAR for the next online meeting; open to everyone.
Natural gas systems are deeply integrated into educational settlements: providing fuel to district energy plants, hospital backup power systems, hot water systems to residence halls and kitchens to name a few. The American Gas Association catalog is fairly stable; reflected in the relative reliability of the US natural gas distribution network. Still, the door is open for discovering and promulgating best practice; driven largely by harmonization with other standards and inevitable “administrivia”. The current edition of the National Fuel Gas Code (ANSI Z223.1) is dated 2024 and harmonizes with NFPA 54.

Why did WTI Crude oil price crash?
1) Because America’s main WTI oil storage is in Cushing in Oklahoma state. Cushing was at 77% capacity on April 17th. Storage would be full by May 1st week. Cushing is landlockded and 800 km from sea. So storing oil on a ship is not possible. pic.twitter.com/Ye2h8XI3jB
Most school districts, colleges, universities and university-affiliated health care systems depend upon a safe and reliable supply of natural gas. Owing to safety principles that have evolved over 100-odd years you hardly notice them. When they fail you see serious drama and destruction.
One of the first names in standards setting for the natural gas industry in the United States is the American Gas Association (AGA) which represents companies delivering natural gas safely, reliably, and in an environmentally responsible way. From the AGA vision statement:
“….(AGA) is committed to leveraging and utilizing America’s abundant, domestic, affordable and clean natural gas to help meet the nation’s energy and environmental needs….”
We do not advocate in natural gas standards at the moment but AGA standards do cross our radar because they assure energy security to the emergent #SmartCampus. We find AGA standards referenced in natural gas service contracts (for large district energy plants, for example) or in construction contracts for new buildings. As with all other energy technological developments we keep pace with, improvements are continual even though those improvements are known to only a small cadre of front line engineers and technicians.
Public consultation on the 2027 National Fuel Gas Code closes June 4, 2024.

“…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?”
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.

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.
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.
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.

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:
Kitchen cooking ranks high as the causes of fire hazard in the built environment. ASHRAE 154 provides design criteria for the performance of commercial cooking ventilation systems. Education communities have hundreds of food preparation enterprises in school districts, residence halls, hospitals and athletic venues. It is not intended to circumvent any safety, health or environmental requirement; however we find a fair amount of drama regarding the competing requirements of fire safety and sustainability among subject matter experts. The stabilized version is dated 2022.
“Dutch Kitchen” / Artist Unknown
A noteworthy title in the ASHRAE standards catalog is ASHRAE 154 Ventilation for Commercial Cooking Operations. Food preparation enterprises in school districts, residence halls, hospitals and athletic venues and central features in education communities. Access to the 2022 edition is linked below:
The purpose of ASHRAE 154 is to provide design criteria for the performance of commercial cooking ventilation systems. It covers kitchen hoods, exhaust systems and replacement air systems, It is not intended to circumvent any safety, health or environmental requirement; however we find a fair amount of drama between partisans of air movement controls and energy conservation interests. Fire safety and the sustainability advocates are well funded voices.
There are no open consultations at the moment; but you may track release of any at the link below:
Titles in the ASHRAE catalog move swiftly; many of them consultations lasting less than 45 days.
Interior environmental air safety is a concern that cuts across many professional disciplines. Accordingly, we maintain this title on the standing agendas of several colloquia — Mechanical Engineering, Energy and Housing. Starting 2022 we will break out this the subject of a separate, dedicated colloquium See our CALENDAR for the next online meeting; open to everyone.

Today we break down consultations on titles relevant to the technology and management of the real assets of education communities in the United States specifically; but with sensitivity to the global education markets where thousands of like-minded organizations also provide credentialing, instruction, research, a home for local fine arts and sport.
“Even apart from the instability due to speculation, there is the instability due to the characteristic of human nature that a large proportion of our positive activities depend on spontaneous optimism rather than on a mathematical expectation, whether moral or hedonistic or economic. Most, probably, of our decisions to do something positive, the full consequences of which will be drawn out over many days to come, can only be taken as the result of animal spirits — a spontaneous urge to action rather than inaction, and not as the outcome of a weighted average of quantitative benefits multiplied by quantitative probabilities. Enterprise only pretends to itself to be mainly actuated by the statements in its own prospectus, however candid and sincere that prospectus may be. Only a little more than an expedition to the South Pole is it based on an exact calculation of benefits to come. Thus if the animal spirits are dimmed and the spontaneous optimism falters, leaving us to depend on nothing but a mathematical expectation, enterprise will fade and die; — though fears of loss may have a basis no more reasonable than hopes of profit had before.”
Extended Versions Certain standards are required to be read in tandem with another standard, which is known as a reference (or parent) document. The extended version (EXV) of an IEC Standard facilitates the user to be able to consult both IEC standards simultaneously in a single, easy-to-use document.
A partial list of projects with which we have been engaged as an active participant; starting with the original University of Michigan enterprise in the late 1990’s and related collaborations with IEEE and others: (In BOLD font we identify committees with open consultations requiring a response from US stakeholders before next month’s Hello World! colloquium)
IEC/TC 8, et al System aspects of electrical energy supply
We collaborate with the appropriate ANSI US TAG; or others elsewhere in academia. We have begun tracking ITU titles with special attention to ITU Radio Communication Sector.

We have collaborations with Rijksuniversiteit Groningen, Sapienza – Università di Roma, Universität Zürich, Universität Potsdam, Université de Toulouse. Universidade Federal de Itajubá, University of Windsor, the University of Alberta, to name a few — most of whom collaborate with us on electrotechnology issues. Standards Michigan and its 50-state affiliates are (obviously) domiciled in the United States. However, and for most issues, we defer to the International Standards expertise at the American National Standards Institute
* A “Hello, World!” program generally is a computer program that outputs or displays the message “Hello, World!”. Such a program is very simple in most programming languages (such as Python and Javascript) and is often used to illustrate the basic syntax of a programming language. It is often the first program written by people learning to code. It can also be used as a sanity test to make sure that a computer language is correctly installed, and that the operator understands how to use it.
