Supporting swimming pools with electricity involves various essential functions such as filtration, heating, lighting, and sanitation. Ensuring safety and energy efficiency is crucial, and pool owners can take steps to minimize electricity costs and environmental impact. Key points:
Filtration and Circulation: Swimming pools rely on electric pumps to circulate water through filters, removing debris and maintaining water quality.
Heating: Electric heaters or heat pumps are used to regulate water temperature for comfort, especially in colder seasons.
Lighting: Underwater and pool area lighting enhance safety and aesthetics, typically powered by electricity.
Chlorination and Sanitation: Electric chlorinators or ozone generators help maintain water cleanliness and hygiene.
Automation: Electric control systems enable pool owners to manage filtration, heating, and lighting remotely for convenience and energy efficiency.
Energy Efficiency: Pool owners can invest in energy-efficient equipment, like variable-speed pumps and LED lighting, to reduce electricity consumption and operating costs.
Operations and Maintenance: Regular electrical maintenance ensures safe and reliable pool operation, preventing electrical faults and hazards. The electricity cost for pool operation can be significant, so pool owners should consider energy-efficient practices and equipment to reduce expenses.
Education communities present one of the largest installed bases of artificially created bodies of water; the most abundance resource on earth. These bodies vary in size, purpose, and design but are all created by human intervention to serve specific needs, whether practical, recreational, or aesthetic. Safe and sustainable management of them in the Unite States are informed by best practice found in Article 680 of the National Electrical Code with scope statement below:
Construction and installation of electrical wiring for, and equipment in or adjacent to, all swimming, wading, therapeutic, and decorative pools; fountains; hot tubs; spas; and hydromassage bathtubs, whether permanently installed or storable, and to metallic auxiliary equipment, such as pumps, filters, and similar equipment.

Bricklayers, sometimes known as masons, are skilled craftsmen that must be physically fit, have a high level of mathematical skill and a love for precision and detail.
Bricklaying standards are guidelines and specifications that ensure the quality and safety of bricklaying work. These standards are often established by industry organizations, regulatory bodies, or national building codes. While specific standards may vary by region, some core bricklaying standards include:
Building Codes: Compliance with local building codes is essential. These codes provide regulations for construction practices, including specifications for masonry work. Bricklayers must adhere to the building codes relevant to the specific location of the construction project.
ASTM International Standards: ASTM International (formerly known as the American Society for Testing and Materials) develops and publishes technical standards for various industries, including construction. ASTM standards related to bricklaying cover materials, testing procedures, and construction practices.
Masonry Construction Standards: Organizations like the Masonry Standards Joint Committee (MSJC) in the United States publish standards specifically focused on masonry construction. These standards address topics such as mortar, grout, reinforcement, and structural design considerations.
Quality Control: Standards related to quality control in bricklaying include specifications for mortar mixtures, proper curing of masonry, and guidelines for inspecting finished work. Adherence to these standards helps ensure the durability and longevity of the masonry construction.
Safety Standards: Occupational safety standards, such as those outlined by the Occupational Safety and Health Administration (OSHA) in the United States, are critical for protecting workers on construction sites. These standards cover aspects like fall protection, scaffolding safety, and the proper use of personal protective equipment.
Brick and Block Standards: Standards related to the dimensions, composition, and properties of bricks and concrete blocks are important for achieving structural integrity. These standards specify characteristics such as compressive strength, absorption, and dimensional tolerances.
Construction Tolerances: Tolerances dictate acceptable variations in dimensions and alignments in bricklaying work. These standards help ensure that the finished structure meets design specifications and industry-accepted tolerances.
Testing and Inspection: Standards related to the testing and inspection of masonry work help verify that construction meets specified requirements. This includes procedures for mortar testing, grout testing, and overall quality inspections.
It’s important for bricklayers and construction professionals to be aware of and follow these standards to guarantee the safety, quality, and compliance of their work. Additionally, staying informed about updates to industry standards is crucial as they may evolve over time to reflect advancements in materials, techniques, and safety practices.

“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.

Laken Riley Act passes 251-170, with 37 Democrats joining all Republicans in support
The murder of Laken Riley occurred on February 22, 2024, in Athens, Georgia. Laken Riley, a 22-year-old nursing student at Augusta University, disappeared when she was jogging at the University of Georgia (UGA). Her body was found near a lake of a wooded area at UGA; her death was caused by blunt force trauma. The police described Riley’s killing as a “crime of opportunity”, and that no murder had been committed at UGA in almost 30 years; a gap filled by the open border policy of Democrat President Joseph Biden, Homeland Secretary Alejandro Mayorkas and chain of Democrat District Attorney’s who let the perpetrator run free.
The murder has international news, generating extensive media attention — though not nearly as much as the George Floyd tragedy and the Black Lives Matter zietgeist — sparking debate over illegal immigration in United States after U.S. Immigration and Customs Enforcement (ICE) confirmed that Ibarra is a Venezuelan illegal immigrant who is not a U.S. citizen and was caught crossing the border but released back into the United States
Jose Antonio Ibarra, a 26-year-old Venezuelan citizen who entered the US illegally, was arrested by UGA police and has been charged with felony murder, false imprisonment, and kidnapping.[4] Ibarra lived about 1 mile (1.6 km) from the area where Riley’s body was found..
European leaders are indifferent to the rape and murder of their young women by migrant men also:
It happened again. Another European girl was killed at the hands of a migrant in Vienna and she wasn’t the first one this week. And tomorrow it will happen again, because white lives don’t matter to our globalist leaders.

“But what is government itself but the greatest of all reflections on human nature? If men were angels, no government would be necessary. If angels were to govern men, neither external nor internal controls on government would be necessary. In framing a government which is to be administered by men over men, the great difficulty lies in this: you must first enable the government to control control the governed; and in the next place oblige it to control itself.” — James Madison, Federalist 51

Sie strahlt vor Freude über ihre Auszeichnung – TH-Alumna Melanie Klaus. Für ihre Bachelorarbeit im Bereich Erneuerbare Energien wurde sie vom Solarenergieförderverein Bayern geehrt. In ihrer Bachelorarbeit im Studiengang Elektro- und Informationstechnik untersuchte sie das Zusammenspiel von Wind- und Solarenergie und den Nutzen, der sich hieraus für die regenerative Energieerzeugung erzielen lässt. Untersucht wurde also die Nutzung der natürlichen Kombination von Wind und Sonne für die Energieerzeugung. Um die Rentabilität dieser Einspeisekombination zu ermitteln, hat Melanie Klaus ein Software-Tool entwickelt, welches zur Planung und Simulation abgestimmter Photovoltaik-Wind-Kombinationen dient und bereits für die Errichtung einer Photovoltaik-Anlage zu einem Windpark eingesetzt wird.
Starting 2023 we break down our coverage of education community energy codes and standards into two tranches:
Energy 200: Codes and standards for building premise energy systems. (Electrical, heating and cooling of the building envelope)
Energy 300: Codes and standards that support the energy systems required for information and communication technology
Energy 400: Codes and standards for energy systems between campus buildings. (District energy systems including interdependence with electrical and water supply)
A different “flavor of money” runs through each of these domains and this condition is reflected in best practice discovery and promulgation. Energy 200 is less informed by tax-free (bonded) money than Energy 400 titles.
Some titles cover safety and sustainability in both interior and exterior energy domains so we simply list them below:
ASME A13.1 – 20XX, Scheme for the Identification of Piping Systems | Consultation closes 6/20/2023
ASME Boiler Pressure Vessel Code
ASME BPVC Codes & Standards Errata and Notices
ASHRAE International 90.1 — Energy Standard for Buildings Except Low-Rise Residential Buildings
2018 International Green Construction Code® Powered by Standard 189.1-2017
NFPA 855 Standard for the Installation of Stationary Energy Storage Systems
IEEE Electrical energy technical literature
ASTM Energy & Utilities Overview
Underwriters Laboratories Energy and Utilities
There are other ad hoc and open-source consortia that occupy at least a niche in this domain. All of the fifty United States and the Washington DC-based US Federal Government throw off public consultations routinely and, of course, a great deal of faculty interest lies in research funding.

Standards Michigan, spun-off in 2016 from the original University of Michigan Business & Finance Operation, has peppered NFPA 70 technical committees writing the 2016-2026 National Electric Code with proposals to reduce the size of building premise feeder infrastructure; accommodating the improvements made in illumination and rotating machinery energy conservation since the 1980’s (variable frequency drives, LED lighting, controls, etc.)
These proposals are routinely voted down in 12-20 member committees representing manufacturers (primarily) though local inspection authorities are complicit in overbuilding electric services because they “bill by the service panel ampere rating”. In other words, when a municipality can charge a higher inspection fee for a 1200 ampere panel, what incentive is there to support changes to the NEC that takes that inspection fee down to 400 amperes?
The energy conservation that would result from the acceptance of our proposals into the NEC are related to the following: reduced step down transformer sizes, reduced wire and conduit sizes, reduced panelboard sizes, reduced electric room cooling systems — including the HVAC cooling systems and the ceiling plenum sheet metal carrying the waste heat away. Up to 20 percent energy savings is in play here and all the experts around the table know it. So much for the economic footprint of the largest non-residential building construction market in the United States — about $120 billion annually.
The market incumbents are complicit in ignoring energy conservation opportunity. To paraphrase one of Mike Anthony’s colleagues representing electrical equipment manufacturers:
“You’re right Mike, but I am getting paid to vote against you.”
NFPA Electrical Division knows it, too.

Rightsizing Commercial Electrical Power Systems: Review of a New Exception in NEC Section 220.12
Michael A. Anthony – James R. Harvey
University of Michigan, Ann Arbor
University of Houston, Clear Lake, Texas
For decades, application of National Electrical Code (NEC) rules for sizing services, feeders and branch circuits has resulted in unused capacity in almost all occupancy classes. US Department of Energy data compiled in 1999 indicates average load on building transformers between 10 and 25 percent. More recent data gathered by the educational facilities industry has verified this claim. Recognizing that aggressive energy codes are driving energy consumption lower, and that larger than necessary transformers create larger than necessary flash hazard, the 2014 NEC will provide an exception in Section 220.12 that will permit designers to reduce transformer kVA ratings and all related components of the power delivery system. This is a conservative, incremental step in the direction of reduced load density that is limited to lighting systems. More study of feeder and branch circuit loading is necessary to inform discussion about circuit design methods in future revisions of the NEC.
