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.
Consultation on the First Draft of the 2026 revision closes August 24, 2024.
“Helen Pluckrose outlines some of the arguments later explored in depth in her bestselling 2020 book, Cynical Theories (co-authored with James Lindsay). The essay charts the pernicious influence of postmodernist thinking on two generations of academics and activists. If you want to understand how we got to a place where microaggressions are denounced as violence but the brutal terrorism of an intifada is considered righteous, this is an important primer.”
“Library Lawn and Chapel; Pembroke College” | James Hart Dyke b. 1966
Blessed are those whose strength is in you,
whose hearts are set on pilgrimage.
As they pass through the Valley of Baka,
they make it a place of springs;
the autumn rains also cover it with pools.
They go from strength to strength,
till each appears before God in Zion.
Hear my prayer, Lord God Almighty;
listen to me, God of Jacob.
Look on our shield, O God;
look with favor on your anointed one.
Better is one day in your courts
than a thousand elsewhere;
I would rather be a doorkeeper in the house of my God
than dwell in the tents of the wicked.
For the Lord God is a sun and shield;
the Lord bestows favor and honor;
no good thing does he withhold
from those whose walk is blameless.
Lord Almighty,
blessed is the one who trusts in you.

International Electrotechnical Commission Technical Committee TC 62 prepares international standards and other publications concerning electrical equipment, electrical systems and software used in healthcare and their effects on patients, operators, other persons and the environment. As such the work of this parent committee — which has broad implications for comparatively cash-rich multi-national medical equipment manufacturers — coordinates the work of several subcommittees; listed below:
62A Common aspects of medical equipment, software and systems
62B Medical imaging equipment, software and systems
62C Equipment for radiotherapy, nuclear medicine and radiation dosimetry
62D Particular medical equipment, software and systems
Germany is Global the Secretariat. The Business Plan is linked below:
The U.S National Committee of the International Electrotechnical Commission serves as the focal point for U.S parties who are interested in the development, promulgation, and use of globally relevant standards for the electrotechnical industry. The USNC is also engaged in the assessment of conformance to standards, undertaking work in areas such as testing, certification, and accreditation. Tony Zertuche is ANSI’s point person (zertuche@ansi.org) and we encourage you to communicate directly with Tony for the most up-to-date information.
We coordinate our response to the development of IEC titles in this domain with the IEEE Education & Healthcare Facilities Committee which meets 4 times monthly in European and American time zones. When there are Committee Draft for Votes released for public consultation (CDV) we coordinate our responses with experts active in IEEE globally.
Since the scope of this committee’s work involves products (in the main) we rank it in the middle of our priority tier. Our primary interest lies with interoperability standards, all the while recognizing that there is very little difference in the way education communities respond to IEC standard proposals than the way all other stakeholders would respond. At the risk of understatement medical research and clinical healthcare delivery are a large part of the revenue of many university systems so that is why we track these titles and others.
We maintain work flow of this committee on our Health, Electrical and Nursing colloquia. See our CALENDAR for the next online meeting; open to everyone.
IEC 63120 ED1: Refurbishment of medical electrical equipment, medical electrical systems and sub-assemblies and reuse of components as part of the extended life-cycle.
We found similar concepts running through the literature among United States consensus product developers; notably the IEEE, NFPA and NEMA. Re-use, reconditioning, recycling of electrical equipment is a priority that can contribute to the safety and sustainability agenda of healthcare enterprises in education communities so we follow it; vigilant for excessive market-making by incumbent verticals.
The comment period lapsed on March 27th but we will likely see more action in the technical committees receiving proposals from vertical incumbents making markets in medical equipment replacement parts. We track development of this and other IEC titles on our provisional workspace*:
We encourage our colleagues working in university-affiliated healthcare enterprises to interact directly with the IEC by setting up a Commenting Account to access the redline linked below:
It is our custom to follow the lead of the the US National Committee to the International Electrotechnical Commission (USNA/IEC) primarily, though we have significant professional relationships with academic scholars in other nations through the IEEE Standards Association and the E&H Committee. We are happy to discuss any consensus product, any day at 11 AM Eastern time, however the expertise for responding to invitations for public comment like this is usually present during the E&H Committee meetings which take place four times monthly in European and American time zones.
