Water and Electricity

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.

Readings: The “30-30” Rule for Outdoor Athletic Events Lightning Hazard

Thunderstorm | Shelter (Building: 30/30 Rule)

The standards for delaying outdoor sports due to lightning are typically set by governing bodies such as sports leagues, associations, or organizations, as well as local weather authorities. These standards may vary depending on the specific sport, location, and level of play. However, some common guidelines for delaying outdoor sports due to lightning include:

  1. Lightning Detection Systems: Many sports facilities are equipped with lightning detection systems that can track lightning activity in the area. These systems use sensors to detect lightning strikes and provide real-time information on the proximity and severity of the lightning threat. When lightning is detected within a certain radius of the sports facility, it can trigger a delay or suspension of outdoor sports activities.
  2. Lightning Distance and Time Rules: A common rule of thumb used in outdoor sports is the “30-30” rule, which states that if the time between seeing lightning and hearing thunder is less than 30 seconds, outdoor activities should be suspended, and participants should seek shelter. The idea is that lightning can strike even when it is not raining, and thunder can indicate the proximity of lightning. Once the thunder is heard within 30 seconds of seeing lightning, the delay or suspension should be implemented.
  3. Local Weather Authority Guidelines: Local weather authorities, such as the National Weather Service in the United States, may issue severe weather warnings that include lightning information. Sports organizations may follow these guidelines and suspend outdoor sports activities when severe weather warnings, including lightning, are issued for the area.
  4. Sports-Specific Guidelines: Some sports may have specific guidelines for lightning delays or suspensions. For example, golf often follows a “Play Suspended” policy, where play is halted immediately when a siren or horn is sounded, and players are required to leave the course and seek shelter. Other sports may have specific rules regarding how long a delay should last, how players should be informed, and when play can resume.

It’s important to note that safety should always be the top priority when it comes to lightning and outdoor sports. Following established guidelines and seeking shelter when lightning is detected or severe weather warnings are issued can help protect participants from the dangers of lightning strikes.

Noteworthy: NFPA titles such as NFPA 780 and NFPA 70 Article 242 deal largely with wiring safety, informed by assuring a low-resistance path to earth (ground)

There are various lightning detection and monitoring devices available on the market that can help you stay safe during thunderstorms. Some of these devices can track the distance of lightning strikes and alert you when lightning is detected within a certain radius of your location. Some devices can also provide real-time updates on lightning strikes in your area, allowing you to make informed decisions about when to seek shelter.

Examples of such devices include personal lightning detectors, lightning alert systems, and weather stations that have lightning detection capabilities. It is important to note that these devices should not be solely relied upon for lightning safety and should be used in conjunction with other safety measures, such as seeking shelter indoors and avoiding open areas during thunderstorms.

Electric Vehicle Charging Stations

Edison electric vehicle | National Park Service, US Department of the Interior

Electrical power engineers know that it is unwise to imagine a totally electric mobility system in the mind’s eye of vertical incumbents, policy makers and trendsniffers.  That does not mean that, as licensed professionals, we cannot positively respond to the demand for more electric mobility on campuses and within school districts.

Today we run through current codes, standards and guides to make that power supply chain safe and sustainable.  Use the login credentials at the upper right of our home page.

In addition to the “NEC canonicals” — listing, coupler heights, disconnect, grounding, voltage, ampacity and overcurrent protection that would likely be applied in a fleet enclosure, more specific passages are relevant when the charging stations are widely dispersed in exterior locations:

Article 225 Outside branch circuits and feeders

Article 625 Electric Vehicle Power Transfer System

We will deal with cable management, IEC 61851 titles, Level 1 & 2 equipment, load management, placement of charging stations at motor fuel dispensing installations and wireless charging systems in a separate session.

Much like designing and building campus outdoor lighting systems, there are more site-related issues to be reckoned with.  For example:

  1. Charging infrastructure: One of the biggest space usage problems with EVs is the need for charging infrastructure. EV owners require access to charging stations in order to recharge their vehicles, and these charging stations can take up valuable space in public areas or campus parking structures that may require additional fire protection systems (that also require upgraded electrotechnologies.
  2. Battery storage: Another space usage issue with EVs is the need for battery storage. EV batteries are large and heavy, and require adequate storage space for safe and secure disposal at the end of their life cycle.
  3. Vehicle size: Many EVs are larger and heavier than traditional gasoline-powered vehicles, which can create space usage problems in urban areas where parking and road space is limited.
  4. Recycling infrastructure: As EVs become more common, the need for specialized recycling infrastructure for EV components, including batteries, motors, and electronics, is likely to increase. These facilities require additional space and resources to safely and efficiently process and recycle these components.

Addressing these space usage problems will require a combination of policy interventions, technological innovations, and public awareness campaigns to promote the benefits and potential of EVs while minimizing their environmental impact and spatial footprint.

ISO Technical Committees | ANSI (U.S. Participation in ISO Activities)

Many large research universities have significant medical research and healthcare delivery enterprises. The leadership of those enterprises discount the effect of standards like this at their peril. It is easy to visualize that this document will have as transformative effect upon the healthcare industry as the ISO 9000 series of management standards in the globalization of manufacturing.

Scope

Standardization in the field of healthcare organization management comprising, terminology, nomenclature, recommendations and requirements for healthcare-specific management practices and metrics (e.g. patient-centered staffing, quality, facility-level infection control, pandemic management, hand hygiene) that comprise the non-clinical operations in healthcare entities.

Excluded are horizontal organizational standards within the scope of:

    • quality management and quality assurance (TC 176);
    • human resource management (TC 260);
    • risk management (TC 262);
    • facility management (TC 267), and;
    • occupational health and safety management (TC 283).

Also excluded are standards relating to clinical equipment and practices, enclosing those within the scope of TC 198 Sterilization of health care products.

This committee is led by the US Technical Advisory Group Administrator —Ingenesis.   The committee is very active at the moment, with new titles drafted, reviewed and published on a near-monthly basis,

Communication in the Presence of Noise

Communication in the Presence of Noise

Claude E. Shannon

University of Michigan – Bell Telephone Laboratories – Massachusetts Institute of Technology

Abstract. A method is developed for representing any communication system geometrically. Messages and the corresponding signals are points in two “function spaces,” and the modulation process is a mapping of one space into the other. Using this representation, a number of results in communication theory are deduced concerning expansion and compression of bandwidth and the threshold effect. Formulas are found for the maximum rate of transmission of binary digits over a system when the signal is perturbed by various types of noise. Some of the properties of “ideal” systems which transmit at this maxmum rate are discussed. The equivalent number of binary digits per second for certain information sources is calculated.

“Electrical Building World’s Columbian Exposition Chicago 1892

Today we feature the catalog of the Illumination Engineering Society — one of the first names in standards-setting in illumination technology, globally* with particular interest in its leading title IES LP-1 | LIGHT + DESIGN Lighting Practice: Designing Quality Lighting for People and Buildings.

From its prospectus:

“…LIGHT + DESIGN was developed to introduce architects, lighting designers, design engineers, interior designers, and other lighting professionals to the principles of quality lighting design. These principles; related to visual performance, energy, and economics; and aesthetics; can be applied to a wide range of interior and exterior spaces to aid designers in providing high-quality lighting to their projects.

Stakeholders: Architects, interior designers, lighting practitioners, building owners/operators, engineers, the general public, luminaire manufacturers.  This standard focuses on design principles and defines key technical terms and includes technical background to aid understanding for the designer as well as the client about the quality of the lighted environment. Quality lighting enhances our ability to see and interpret the world around us, supporting our sense of well-being, and improving our capability to communicate with each other….”

Illumination technologies run about 30 percent of the energy load in a building and require significant human resources at the workpoint — facility managers, shop foremen, front-line operations and maintenance personnel, design engineers and sustainability specialists.  The IES has one of the easier platforms for user-interest participation:

IES Standards Open for Public Review

Because the number of electrotechnology standards run in the thousands and are in continual motion* we need an estimate of user-interest in any title before we formally request a redline because the cost of obtaining one in time to make meaningful contributions will run into hundreds of US dollars; apart from the cost of obtaining a current copy.

We maintain the IES catalog on the standing agendas of our Electrical, Illumination and Energy colloquia.   Additionally, we collaborate with experts active in the IEEE Education & Healthcare Facilities Committee which meets online 4 times monthly in European and American time zones; all colloquia online and open to everyone.   Use the login credentials at the upper right of our home page to join us.

Today we break down the literature for building, maintaining and supporting the computing infrastructure of education settlements.  We use the term “infotech” gingerly to explain action for a  broad span of technologies that encompass enterprise servers and software, wireless and wired networks, campus phone networks, and desktop computers that provide administrative services and career tech video production.   The private sector has moved at light speed to respond to the circumstances of the pandemic; so have vertical incumbents evolving their business models to seek conformance revenue.  Starting 2023 we break down the topic accordingly:

Infotech 200:  Wired and wireless infrastructure for education and administration related to teaching sciences and supporting fine and lively arts

Infotech 400:  Physical system middleware for research facilities; data center location, power supply, cooling systems, fire suppression, security, monitoring and management.

The literature radiates continually by consortia, open-source, or ad hoc standards-setting domains rather than the private standards system administered by global and standards setting bodies; to wit:

International:

IEC (EN 50600), IET, ISO, ITU

Freely Available ICT Standards

IEEE

Education & Healthcare Facility Electrotechnology Committee

United States:

ASHRAE

BICSI

Data Center Operations and Maintenance Best Practices

INCITS, NFPA, NIST, TIA (942)

Everywhere else:

3GPP & 3GPP2,  Apache Software Foundation,  ISTE,  OneM2M,  Uptime Institute

The ICT domain is huge, replacing physical libraries.  The foregoing is a highly curated sample.

We continue to include teaching and learning media standards on our colloquia however it is likely that will break up this topic into at least two related colloquia as 2022 proceeds; with primary focus on the design, construction and maintenance of the physical ICT infrastructure.  Much depends upon the interest of our clients, colleagues and other stakeholders.  We collaborate closely with the IEEE Education and Healthcare Electrotechnology Committee.

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.

Guide for Animal Deterrents for Electric Power Supply Substations

1264-2022 – IEEE Guide for Animal Mitigation for Electric Power Supply Substations

IEEE Power Engineering Society

Abstract: Documented in this guide are methods and designs to mitigate interruptions, equipment damage, and personnel safety issues resulting from animal intrusions into electric power supply substations, thereby improving reliability and safety, and minimizing the associated revenue loss.
Scope: This guide documents methods and designs to mitigate interruptions, equipment damage, and personnel safety issues resulting from animal intrusions into electric power supply substations, thereby improving reliability and safety, and minimizing the associated revenue loss.
Purpose: Intrusion by animals into electric power supply substations has been a problem experienced by most of the electric utility industry. The costs associated with outages caused by animals continue to escalate. Although animal problems differ in nature geographically, the damage to equipment, interruption of or loss of service to customers, and safety problems encountered by operating personnel result in similar general concerns. This guide identifies various animals, the problems they cause, and mitigation methods. Further, it recommends criteria for applying mitigation methods, documents survey-reported effectiveness of various methods, and recommends factors for evaluating effectiveness of methods once they are applied.
