A standard Olympic-sized swimming pool is defined by the following dimensions:
Length: 50 meters
Width: 25 meters
Depth: A minimum of 2 meters
Lanes: 10 lanes, each 2.5 meters wide
The total area of the pool is therefore 1,250 square meters, and it holds approximately 2,500 cubic meters (or 2.5 million liters) of water.
The organization that sets the standards for Olympic-sized pools is the Fédération Internationale de Natation (FINA) — now World Aquatics — the governing body for swimming, diving, water polo, synchronized swimming, and open water swimming. FINA establishes the regulations for the dimensions and equipment of competition pools used in international events, including the Olympic Games.
The top ten universities that have produced Olympic champion:
“In swimming, there are no referees, no foul lines,
no time-outs, and no substitutions.
It’s just you and the water.” – Unknown
There are several specific problems that swimming pool overhead lighting aims to solve:
Visibility: Swimming pool overhead lighting is designed to improve visibility in and around the pool. This is important for safety reasons, as it helps swimmers see where they are going and avoid obstacles or hazards.
Aesthetics: Overhead lighting can enhance the appearance of the swimming pool by creating a visually appealing atmosphere. This is especially important for commercial pools where the aesthetics can be an important factor in attracting customers.
Functionality: Overhead lighting can provide additional functionality by allowing the pool to be used during evening hours or in low light conditions. This can increase the usability of the pool and make it more appealing to users.
Energy efficiency: Modern overhead pool lighting solutions are designed to be energy-efficient, reducing the overall energy consumption and operating costs of the pool.
Longevity: Overhead pool lighting must be designed to withstand exposure to water, chlorine, and other harsh chemicals, as well as exposure to the elements. The lighting system must be durable and reliable to ensure longevity and prevent costly repairs or replacements.
Overall, swimming pool overhead lighting is an important component of a safe, functional, and visually appealing pool. It provides illumination for visibility, enhances aesthetics, and improves functionality, while also being energy-efficient and durable.
After athletic arena life safety obligations are met (governed legally by NFPA 70, NFPA 101, NFPA 110, the International Building Code and possibly other state adaptations of those consensus documents incorporated by reference into public safety law) business objective standards may come into play. For almost all athletic facilities, the consensus documents of the Illumination Engineering Society[1], the Institute of Electrical and Electronic Engineers[2][3] provide the first principles for life safety. For business purposes, the documents distributed by the National Collegiate Athletic Association inform the standard of care for individual athletic arenas so that swiftly moving media production companies have some consistency in power sources and illumination as they move from site to site. Sometimes concepts to meet both life safety and business objectives merge.
During water sport season the document linked below provides information to illumination designers and facility managers:
Athletic programs are a significant source of revenue and form a large part of the foundation of the brand identity of most educational institutions in the United States. We focus primarily upon the technology standards that govern the safety, performance and sustainability of these enterprises. We collaborate very closely with the IEEE Education & Healthcare Facilities Committee where subject matter experts in electrical power systems meet 4 times each month in the Americas and Europe.
See our CALENDAR for our next colloquium on Sport facility codes and standards. We typically walk through the safety and sustainability concepts in play; identify commenting opportunities; and find user-interest “champions” on the technical committees who have a similar goal in lowering #TotalCostofOwnership.

“…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.

The American Water Works Association is one of the first names in accredited standards developers that administer leading practice discovery in backflow prevention consensus documents; usually referenced in local and state building codes; and also in education facility design guidelines and construction specifications.
The original University of Michigan standards enterprise gave highest priority to backflow standards because of their central importance of backflow management to education communities; especially large research universities nested within a municipal water system. Backflow prevention; an unseen technology that assures a safe drinking water supply by keeping water running in one direction by maintaining pressure differences. Analogous to the way we want electrical current to run in one direction, failure of backflow prevention technology poses a near-instantaneous health risk for the contamination of potable water supplies with foul water. In the most obvious case, a toilet flush cistern and its water supply must be isolated from the toilet bowl. In a less obvious case, but at greater scale, a damaged backflow prevention technology at a university research building can contaminate an host-community potable water supply.
There are other ANSI accredited standards developers in the backflow prevention technology space — the International Code Council, the IAPMO Group and ASSE International — for example.

The IAPMO code development process is one of the best in the land. Its Read-Only Access — needed for light research — is also the best in the land; unlike other ANSI accredited standards developers (who shall be un-named). The current edition is dated 2024, with the 2027 revision accepted public input until March 3, 2025 according the schedule linked below:

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:
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:

Education communities provide a large market for recreational and therapeutic water technology suppliers. Some of the larger research universities have dozens of pools including those in university-affiliated healthcare facilities. Apart from publicly visible NCAA swimming programs there are whirpools in healthcare facilities and therapeutic tubs for athletes in other sports. Ownership of these facilities requires a cadre of conformance experts to assure water safety.
NSF International is one of the first names in this space and has collaborated with key industry stakeholders to make pools, spas and recreational water products safer since 1949. The parent document in its suite isNSF 50 Pool, Spa and Recreational Water Standards which covers everything from pool pumps, strainers, variable frequency drives and pool drains to suction fittings, grates, and ozone and ultraviolet systems.
(Standards Michigan is an observer on this and several other NSF committees and is the only “eyes and ears” for the user interest; arguably the largest market for swimming pools given their presence in schools and universities.)
There are 14 task groups that drill into specifics such as the following:
Chemical feeders
Pool chemical evaluation
Flotation systems
Filters
Water quality
Safety surfacing
The meeting packet is confidential to registered attendees. You may communicate directly with the NSF Joint Committee Chairperson, Mr. Tom Vyles (admin@standards.nsf.org) about arranging direct access as an observer or technical committee member.
Almost all ANSI accredited technical committees have a shortage of user-interests (compliance officers, manufacturers and installers usually dominate). We encourage anyone in the education facility industry paying the bill for the services of compliance officers, manufacturers and installers to participate.
We maintain this title on the standing agenda of our Water and Sport colloquia. See our CALENDAR for the next onine meeting; open to everyone.
