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.
Ampere current flows through copper or aluminum conductor due to the movement of free electrons in response to an applied electric field of varying voltages. Each copper or aluminum contributes one free electron to the electron sea, creating a vast reservoir of mobile charge carriers. When a potential difference (voltage) is applied across the ends of the conductor, an electric field is established within the conductor. This field exerts a force on the free electrons, causing them to move in the direction of the electric field. The resulting current flow can be transformed into different forms depending on the nature of the device.
Heating: When current flows through a resistor, it encounters resistance, which causes the resistor to heat up. This is the principle behind electric heaters, toasters, and incandescent light bulbs.
Mechanical Work: Current flowing through an electric motor creates a magnetic field, which interacts with the magnetic field of the motor’s permanent magnets or electromagnets. This interaction generates a mechanical force, causing the motor to rotate. Thus, electrical energy is converted into mechanical energy; including sound.
Light: In an incandescent light bulb, a filament heats up ( a quantum phenomena) due to the current passing through it. This is an example of electrical energy being converted into light energy; including the chemical energy through light emitting diodes
Today we dwell on how conductors are specified and installed in building premise wiring systems primarily; with some attention to paths designed to carry current flowing through unwanted paths (ground faults, phase imbalance, etc). In the time we have we will review the present state of the best practice literature developed by the organizations listed below:
Other organizations such as the National Electrical Manufacturers Association, ASTM International, Underwriter Laboratories, also set product and installation standards. Data center wiring; fiber-optic and low-voltage control wiring is covered in other colloquia (e.g. Infotech and Security) and coordinated with the IEEE Education & Healthcare Facilities Committee.

Some of the common electro-technologies used in a neonatal care unit include:
Incubators: These temperature-controlled units create a controlled environment to keep premature or sick infants warm and protected.
Ventilators: Mechanical ventilators assist newborns with respiratory distress by delivering oxygen and helping them breathe.
Monitors: These devices track vital signs such as heart rate, oxygen levels, blood pressure, and temperature to ensure the baby’s health and detect any abnormalities.
Phototherapy Lights: Special lights are used to treat jaundice in newborns, helping to break down excess bilirubin in the blood.
Intravenous Pumps: These pumps are used to deliver medications, fluids, and nutrients directly into the baby’s bloodstream.
Feeding Tubes: For infants who are unable to feed orally, feeding tubes are used to deliver breast milk or formula directly into their stomach.
Blood Gas Analyzers: These machines measure the levels of oxygen, carbon dioxide, and other gases in a baby’s blood to monitor respiratory status and acid-base balance.
Infusion Pumps: Used to administer controlled amounts of fluids, medications, or nutrients to newborns.
CPAP/BiPAP Machines: Continuous Positive Airway Pressure (CPAP) and Bi-level Positive Airway Pressure (BiPAP) machines help newborns with breathing difficulties by providing a continuous flow of air pressure.
Neonatal Resuscitation Equipment: This includes equipment such as resuscitation bags, endotracheal tubes, laryngoscopes, and suction devices used during emergency situations to assist with newborn resuscitation.
It’s important to note that specific tools and equipment may vary depending on the level of neonatal care provided by the unit, the needs of the infants, and the policies of the healthcare facility.
Neonatal care, as a specialized field, has been shaped by the contributions of several pioneers in medicine. Here are a few notable figures who have made significant advancements in neonatal care:
Dr. Virginia Apgar was an American obstetrical anesthesiologist who developed the Apgar score in 1952. The Apgar score is a quick assessment tool used to evaluate the overall health of newborns immediately after birth. It assesses the baby’s heart rate, respiratory effort, muscle tone, reflex irritability, and color, providing valuable information for prompt intervention and monitoring.
Dr. Martin Couney, a pioneering physician, established incubator exhibits at world fairs and amusement parks in the early 20th century. He promoted the use of incubators to care for premature infants and played a significant role in popularizing the concept of neonatal intensive care.
Dr. Virginia A. Apgar, an American pediatrician and neonatologist, made significant contributions to the field of neonatology. She specialized in the care of premature infants and conducted extensive research on neonatal resuscitation and newborn health. She also developed the Apgar scoring system, although unrelated to Dr. Virginia Apgar mentioned earlier.
Dr. Lula O. Lubchenco was an influential researcher and neonatologist who made important contributions to the understanding of newborn growth and development. She developed the Lubchenco Growth Chart, which provides a standardized assessment of a newborn’s size and gestational age, aiding in the identification and monitoring of growth abnormalities.
Dr. Mary Ellen Avery was a renowned American pediatrician and researcher whose work focused on understanding and treating respiratory distress syndrome (RDS) in premature infants. She identified the importance of surfactant deficiency in RDS and contributed to the development of surfactant replacement therapy, revolutionizing the care of preterm infants.
These individuals, among many others, have played pivotal roles in advancing the field of neonatal care, improving the understanding, diagnosis, treatment, and overall outcomes for newborn infants.
The Illumination Engineering Societyis one of the first names in standards-setting organizations with a catalog routinely referenced in design guidelines and construction projects. Because of the money flow into illumination technologies worldwide the IES occupies a domain that is relatively crowded:
National Electrical Manufacturers and Medical Imaging Association; whose interest lies in leveling the playing field for about 300 electrical equipment manufacturers
Institute for Electrical and Electronic Engineers; whose interest lies in the research activity in seeing sciences, the luminescence sources and the power chain
American Society of Heating and Refrigeration Engineers; whose interest lies in energy conservation
National Fire Protection Association; whose interest lies in fire safety of lighting systems within building premises.
International Code Council; whose interest lies in pulling together all of the relevant standards for lighting egress paths of the built environment
International Electrotechnical Commission; whose interest lies in the administration of global electrical and electronic technologies
International Commission on Illumination; the international authority on light, illumination, colour, and colour spaces
There are others. With illumination power requirement on a downward trajectory where footcandles can be driven at information & communication technology voltage and current levels; we find relatively new entrants into the market with deep pockets and for good reason. In a typical building, the interior lighting load is the major electrical load (on the order of 40 percent) and a major contributor to the functionality of the building. There are a number of other trade associations that are participants in research and open source standards for faster moving parts of the illumination science. We will cover these in future, related posts.
Last year a new standardization project was launched by the IES. From the project prospectus:
IES LP-2-201x, Designing Quality Lighting for People in Outdoor Environments (new standard)
Project Need: This document is not intended to supersede existing IES application RPs, rather it will link the various documents together, augmenting them in subject areas not otherwise covered, including but not limited to sidewalks, bikepaths, pedestrian paths, parks, outdoor malls, pedestrian-only business districts, plazas, amphitheaters, large outdoor gathering areas, campuses, pedestrian bridges, and pedestrian underpasses.
Stakeholders: Lighting practitioners, electrical engineers, civic planners, civil engineers, architects, community-based planning groups, general public. Lighting recommendations for non-vehicular pedestrian applications using recommendations beyond illuminance only, which ultimately fails to provide a complete guideline for the visual experience of pedestrian-based tasks. The RP will be a comprehensive approach for light levels, glare, adaptation, spectrum, and contrast while addressing safety, timing, and perceived security. Application of these recommendations will ultimately enhance the pedestrian’s visual experience while also respecting the environment.
Soon to be released, a related product covering technical specifics of a familiar battleground — lighting controls:
The consultation closed May 24th and the agenda of the committee writing this standard is being administered. Very often technical committees are receptive to new ideas after a comment deadline if those ideas are submitted to a committee member directly. We invite anyone with an interest in this topic to click in to any of our daily colloquia to begin that process.
Not far into the future: individually controlled luminaires responsive to the use of campus pathways. There are already some pilot projects on higher education campuses.
A few other technical committees relevant to educational communities should be identified, though we will sort through the standards setting activity in separate posts:
We always encourage direct participation by space planners, workpoint experts and academic unit facility managers in IES standards development process. Contact: Patricia McGillicuddy, (917) 913-0027, pmcgillicuddy@ies.org. 120 Wall Street, Floor 17, New York, NY.
We coordinate most of our electrotechnology standards advocacy with the IEEE Education & Healthcare Facilities Committee which meets 4 times monthly in European and American time zones. Its meeting agendas and login credentials are available on its website. Since illumination technologies are present in all spaces in education communities, IES consensus products will appear on the standing agenda of most disciplines. See our CALENDAR.
Many land grant colleges and universities are stewards of agricultural facilities that require reliable electrical power that is safe and sustainable for livestock well off the core campus distribution grid. Today we examine the 2026 National Electrical Code safe electric service rules with an eye toward the close date of April 6th for public input on the 2029 NEC.
Many land grant colleges and universities are stewards of agricultural facilities that require reliable electrical power that is safe and sustainable for livestock and animal habitat for sporting.
The premise wiring rules for hazardous university owned buildings have been relatively stable. Electrical professionals are guided by:
Farm Load Calculations of Part V of Article 220,
Corrosion mitigation with appropriate specification of power chain wiring
Stray voltage and the equipotential plane
Interactivity with regulated utility power sources.
Public response to the First Draft of the 2026 National Electrical Code will be received until August 28, 2024. We coordinate our approach to the entire NFPA electrical suite with the IEEE Education & Healthcare Facilities Committee which meets 4 times monthly. We typically refer to previous transcripts of technical committee actions to inform any changes (improvements) that we propose, if any.
We maintain this issue on the standing agenda of our Power and Nourriture (Food) colloquia. Feel free to join us with the login credentials at the upper right of our home page.
IEC 60364-1:2025 (6th edition, published September 5, 2025) replaces the 2005 edition (5th edition). This is a major technical revision with significant changes which we will cover throughout 2026 — after NESC and NEC work
“View of Lake Geneva” 1881 Gustave Courbet
Technical Committee 64 develops the International Electrotechnical Commission consensus product that covers similar territory for the global electrical power industry as NFPA 70 (National Electrical Code). Keep in mind that the safety traditions of the NFPA suite of consensus products are inspired by fire safety considerations. IEC 60363 Electrical installations and protection against electric shock — the parent document that applies to the wiring systems of education and healthcare facilities — was inspired from voltage safety.
– concerning protection against electric shock arising from equipment, from installations and from systems without limit of voltage,
– for the design, erection foreseeable correct use and verification of all kind of electrical installations at supply voltage up to 1 kV a.c or 1,5 kV d.c., except those installations covered by the following IEC committees: TC 9, TC 18, TC 44, TC 97, TC99
– in co-ordination with TC 99, concerning requirements additional to those of TC 99 for the design, erection and verification of electrical installations of buildings above 1kV up to 35kV.
The object of the standards shall be:
– to lay down requirements for installation and co-ordination of electrical equipment
– to lay down basic safety requirements for protection against electric shock for use by technical committees
– to lay down safety requirements for protection against other hazards arising from the use of electricity
– to give general guidance to IEC member countries that may have need of such requirements
– and to facilitate international exchanges that may be hampered by differences in national regulations.
The standards will not cover individual items of electrical equipment other than their selection for use. Safety Pilot Function: Protection against electric shock.
Since neither the USNA National Committee to the IEC (USNA/IEC), nor the US Technical Advisory Administrator (National Electrical Manufacturers Association) has a workspace set up for responding to IEC 60364 calls for public comment, we set one up for ourselves several years ago for education facility and electrical engineering faculty and students:
Note that anyone in the world is welcomed to comment upon IEC documents, contingent upon obtaining (free) login credentials. To review the the strike-and-bold you will need login credentials. Alternatively, you may click in to the 4-times monthly teleconferences of the IEEE Education & Healthcare Facilities Committee. See our CALENDAR for the next online meeting.

Abstract: This paper presents a broad view of management of design and implementation of power systems for Data Centers. The paper outlines many challenges that are present because of the demanding requirements of Data Centers both in design and management, then introduces opportunities that recent technological advances have made possible. This paper presents several new approaches of ownership and responsibilities that directly affect financial viability of the Data Center.
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:
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.
Education estate managers, energy conservation workgroups, sustainability officers, electric shop foreman, electricians and front-line maintenance professionals who change lighting fixtures, maintain environmental air systems are encouraged to participate directly in the ASHRAE consensus standard development process.
We also maintain ASHRAE best practice titles as standing items on our Mechanical, Water, Energy and Illumination colloquia. See our CALENDAR for the next online meeting; open to everyone.

* Many standards-developing organizations aim to broaden their influence by entering the product standard and certification domain. Although our primary focus is on interoperability standards (within a system of interoperable products), we also consider market dynamics when product performance specifications are incorporated by reference into public law.
To paraphrase Marc Andreessen: “Building standards are eating the world and ASHRAE is eating building standards” (– Mike Anthony, University of Michigan). Just when you thought ASHRAE’s claim to energy regulation could not get any larger, it has recently appropriated everything *between* buildings in its scope — that means all above-ground pathway lighting, steam, hot water communication cabling tunnels, water pumps, fire protections systems; among others.
