“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:
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.

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.

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 is NSF 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.
The workspace for this committee is linked below:
Joint Committee on Recreational Water Facilities
(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.

The choice of red, white, and blue in national flags often carries historical, cultural, and political significance. Here are some reasons why various nations have chosen these colors:
The exact reasons can vary, but often the colors reflect a mix of historical alliances, cultural heritage, and political ideals.

The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) is an ANSI-accredited continuous-maintenance standards developer (a major contributor to what we call a regulatory product development “stream”). Continuous maintenance means that changes to its consensus products can change in as little as 30 days so it is wise to keep pace.
Among the leading titles in its catalog is ASHRAE 90.1 Energy Standard for Sites and Buildings Except Low-Rise Residential Buildings. Standard 90.1 has been a benchmark for commercial building energy codes in the United States and a key basis for codes and standards around the world for more than 35 years. Free access to ASHRAE 90.1 version is available at the link below:
READ ONLY Version of 2022 ASHRAE 90.1
Redlines are released at a fairly brisk pace — with 30 to 45 day consultation periods. A related title — ASHRAE 189.1 Standard for the Design of High Performance Green Buildings — first published in 2009 and far more prescriptive in its scope heavily references parent title 90.1 so we usually them as a pair because 189.1 makes a market for green building conformance enterprises. Note the “extreme prescriptiveness” (our term of art) in 189.1 which has the practical effect of legislating engineering judgement, in our view.

FIREWORKS: PYROTECHNIC ARTS AND SCIENCES IN EUROPEAN HISTORY
Simon Werrett | University College London
Fireworks are synonymous with celebration in the twenty-first century. But pyrotechnics—in the form of rockets, crackers, wheels, and bombs—have exploded in sparks and noise to delight audiences in Europe ever since the Renaissance. Here, Simon Werrett shows that, far from being only a means of entertainment, fireworks helped foster advances in natural philosophy, chemistry, mathematics, and many other branches of the sciences.
Fireworks brings to vibrant life the many artful practices of pyrotechnicians, as well as the elegant compositions of the architects, poets, painters, and musicians they inspired. At the same time, it uncovers the dynamic relationships that developed between the many artists and scientists who produced pyrotechnics. In so doing, the book demonstrates the critical role that pyrotechnics played in the development of physics, astronomy, chemistry and physiology, meteorology, and electrical science. Richly illustrated and drawing on a wide range of new sources, Fireworks takes readers back to a world where pyrotechnics were both divine and magical and reveals for the first time their vital contribution to the modernization of European ideas.
