“Having visited my great grandmother, Omi, in Germany multiple times growing up, I’ve always had a special connection to German baked goods. While I have yet to find the perfect German pretzel in the U.S. or a recipe that yields a decent replica, I have discovered that stollen — a traditional German Christmas bread — is relatively easy to recreate in my own kitchen.” — Alison Tashima, Class of 2024
“I know that I am mortal by nature, and ephemeral;
but when I trace at my pleasure the windings to and fro of the heavenly bodies,
I no longer touch Earth with my feet:
I stand in the presence of Zeus himself and take my fill of ambrosia.”
— Ptolemy, “Mathematike Syntaxis” 150 A.D

Planetariums in schools and colleges play a central in enhancing astronomy and astrophysics education. They provide immersive experiences that can ignite students’ interest and curiosity about the universe, making complex astronomical concepts more comprehensible and engaging. Observatories do much that but with direct access to telescopes and other observational tools — frequently away from campus — thus allowing them to engage in hands-on learning and real-time data collection.
Establishing research and teaching programs present special occupancy challenges. The cost of high-quality telescopes and equipment, along with the need for a suitable location with minimal light pollution, can be substantial. Additionally, schools require trained staff to guide students in using the equipment and interpreting data. Weather conditions and geographical location also impact the effectiveness of observatories. Despite these hurdles, the educational value of observatories is immense, providing students with unique opportunities to explore the universe and cultivate a passion for scientific inquiry.
The International Building Code includes various sections that address safety requirements relevant to observatories and planetariums. Key parts of the IBC that cover these requirements include:
Chapter 3: Use and Occupancy Classification
Section 303: Assembly Group A. Planetariums and observatories often fall under Assembly Group A due to their function as places where people gather for educational and entertainment purposes. Specific occupancy types and associated requirements will be detailed here.
Chapter 4: Special Detailed Requirements Based on Use and Occupancy
Section 410: Stages, Platforms, and Technical Production Areas. While not specific to planetariums, this section provides guidance on assembly spaces, which may be applicable to the design and safety considerations for the auditorium areas in planetariums.
Chapter 11: Accessibility
Section 1103: Scoping Requirements. This section ensures that buildings are accessible to individuals with disabilities, which is crucial for public facilities like planetariums and observatories.
Section 1104: Accessible Routes. Requirements for accessible paths to ensure ease of access to and within the facility.
Chapter 12: Interior Environment
Section 1203: Ventilation. Adequate ventilation is essential in enclosed spaces like planetariums to ensure air quality and comfort.
Section 1205: Lighting. Ensuring appropriate lighting levels and types, which is crucial in areas like control rooms and observational spaces.
Chapter 15: Roof Assemblies and Rooftop Structures
Section 1509: Rooftop Structures. Covers the installation and safety of rooftop observatories, which can include structural requirements and access considerations.
Chapter 16: Structural Design
Section 1604: General Design Requirements. Ensures that the structure can support both the static and dynamic loads associated with heavy equipment like telescopes.
Section 1607: Live Loads. Specific load requirements for observatory equipment and public assembly areas.
These chapters collectively ensure that planetariums and observatories are designed and constructed with safety, accessibility, and functionality in mind. For detailed information, it is recommended to refer to the latest edition of the IBC and consult with a professional knowledgeable in building codes and standards.
World Astronomy Day is Saturday, and to celebrate we are showing off some of our favorite pictures of the Albion College Observatory. The Albion College Observatory was constructed from 1883-1884 under the direction of Dr. Samuel Dickie. #ThrowbackThursday#TBT#MyAlbionpic.twitter.com/ixgtAMlP4z
Designing and building a telescope for teaching and light research at a college or university requires a detailed consideration of both the telescope itself and the supporting infrastructure. Here are the central architectural features:

“…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.

Michigan can 100% water and feed itself. Agriculture is its second-largest industry.
The largest planetarium on a U.S. college or university campus is the Fiske Planetarium at the University of Colorado Boulder. The Fiske Planetarium features a 65-foot diameter dome and has undergone significant technological upgrades, making it one of the most advanced planetariums in the country. It offers a variety of shows, including live demonstrations and immersive experiences that simulate different cosmic phenomena and environments (CU Connections).
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.

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:
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.
