…”There’s not good math explaining forget the physics of it. Math explaining the behavior of complex systems yeah and that to me is both exciting and paralyzing like we’re at very early days of understanding you know how complicated and fascinating things emerge from simple rules…” — Peter Woit [1:16:00]
Since 1936 the Brown Jug has been the ancestral trough of generations of University of Michigan students and faculty — notably. Donald Glaser (inventor of the bubble chamber) and Samuel C. C. Ting (Nobel Laureate) whose offices at Randall Laboratory were a 2-minute walk around the corner from The Brown Jug. As the lore goes, the inspiration happened whilst watching beer bubbles one ordinary TGIF Friday.
When is it ever NOT storm season somewhere in the United States; with several hundred schools, colleges and universities in the path of them? Hurricanes also spawn tornadoes. This title sets the standard of care for safety, resilience and recovery when education community structures are used for shelter and recovery. The most recently published edition of the joint work results of the International Code Council and the ASCE Structural Engineering Institute SEI-7 is linked below:
Given the historic tornados in the American Midwest this weekend, its relevance is plain. From the project prospectus:
The objective of this Standard is to provide technical design and performance criteria that will facilitate and promote the design, construction, and installation of safe, reliable, and economical storm shelters to protect the public. It is intended that this Standard be used by design professionals; storm shelter designers, manufacturers, and constructors; building officials; and emergency management personnel and government officials to ensure that storm shelters provide a consistently high level of protection to the sheltered public.
This project runs roughly in tandem with the ASCE Structural Engineering Institute SEI-17 which has recently updated its content management system and presented challenges to anyone who attempts to find the content where it used to be before the website overhaul. In the intervening time, we direct stakeholders to the link to actual text (above) and remind education facility managers and their architectural/engineering consultants that the ICC Code Development process is open to everyone.
The ICC receives public response to proposed changes to titles in its catalog at the link below:
You are encouraged to communicate with Kimberly Paarlberg (kpaarlberg@iccsafe.org) for detailed, up to the moment information. When the content is curated by ICC staff it is made available at the link below:
We maintain this title on the agenda of our periodic Disaster colloquia which approach this title from the point of view of education community facility managers who collaborate with structual engineers, architects and emergency management functionaries.. See our CALENDAR for the next online meeting, open to everyone.
The original University of Michigan codes and standards enterprise advocated actively in Article 708 Critical Operations Power Systems (COPS) of the National Electrical Code (NEC) because of the elevated likelihood that the education facility industry managed assets that were likely candidates for designation critical operations areas by emergency management authorities.
Because the NEC is incorporated by reference into most state and local electrical safety laws, it saw the possibility that some colleges and universities — particularly large research universities with independent power plants, telecommunications systems and large hospitals — would be on the receiving end of an unfunded mandate. Many education facilities are identified by the Federal Emergency Management Association as community storm shelters, for example.
As managers of publicly owned assets, University of Michigan Plant Operations had no objection to rising to the challenge of using publicly owned education facilities for emergency preparedness and disaster recovery operations; only that meeting the power system reliability requirements to the emergency management command centers would likely cost more than anyone imagined — especially at the University Hospital and the Public Safety Department facilities. Budgets would have to be prepared to make critical operations power systems (COPS) resistant to fire and flood damages; for example.
Collaboration with the Institute of Electrical and Electronic Engineers Industrial Applications Society began shortly after the release of the 2007 NEC. Engineering studies were undertaken, papers were published (see links below) and the inspiration for the IEEE Education & Healthcare Facilities Committee developed to provide a gathering place for power, telecommunication and energy professionals to discover and promulgate leading practice. That committee is now formally a part of IEEE and collaborates with IAS/PES JTCC assigned the task of harmonizing NFPA and IEEE electrical safety and sustainability consensus documents (codes, standards, guidelines and recommended practices.
The 2023 Edition of the National Electrical Code does not contain revisions that affect #TotalCostofOwnership — only refinement of wiring installation practices when COPS are built integral to an existing building that will likely raise cost. There are several dissenting comments to this effect and they all dissent because of cost. Familiar battles over overcurrent coordination persist.
Our papers and proposals regarding Article 708 track a concern for power system reliability — and the lack of power — as an inherent safety hazard. These proposals are routinely rejected by incumbent stakeholders on NEC technical panels who do not agree that lack of power is a safety hazard. Even if lack of power is not a safety hazard, reliability requirements do not belong in an electrical wiring installation code developed largely by electricians and fire safety inspectors. The IEEE Education & Healthcare Facilities Committee (IEEE E&H) maintains a database on campus power outages; similar to the database used by the IEEE 1366 committees that develop reliability indices to enlighten public utility reliability regulations.
Public input on the 2026 revision to the NEC will be received until September 7th. We have reserved a workspace for our priorities in the link below:
Information and communications technology (ICT) is a fast-moving economic space in which a mix of consensus, consortia and open-source standards form the broad contours of leading practice. ICT standards tend to follow international developments — more so than, say, fire safety standards which are more familiar to education facility leadership. All school districts, colleges, universities and university-affiliated health care systems have significant product, system, firmware and labor resources allocated toward ICT.
The Building Industry Consulting Service International (BICSI) is a professional association supporting the advancement of the ICT community in all markets. This community is roughly divided between experts who deal with “outside-plant” systems and “building premise” systems on either side of the ICT demarcation (or Point-of-Presence). BICSI standards cover the wired and wireless spectrum of voice, data, electronic safety & security, project management and audio & video technologies. Its work is divided among several committees as shown in the landing page of its standards setting enterprise, linked below:
The stars on the map above indicate where BICSI Standards are currently in use (CLICK ON IMAGE).
Education communities are stewards of significant information and communication technology infrastructure. Accordingly, we track the development of BICSI 009 Data Center Operations and Maintenance Best Practices. This title provides requirements, recommendations, and best practices for the operation and maintenance of data centers including but not limited to standard operating procedures, emergency operating procedures, maintenance, governance, and management. Those comments are now being integrated into a revised standard to be released as soon as the restrictions of the pandemic are eased. For more information you may communicate directly with Jeff Silveira (jSilveira@bicsi.org)
As of this posting, all BICSI best practice titles are stable and current; though our recent communication with its leadership indicates that BICSI standards setting has been slowed by the pandemic.
A fair amount of content in BICSI standards are inspired by movement in safety concepts of the National Electrical Code; particularly on matters involving wiring, grounding and lightning protection. We maintain all BICSI best practice titles on the standing agenda of our Infotech 200 teleconference. See our CALENDAR for the next online meeting; open to the public. On this topic we collaborate with the IEEE Education & Healthcare Facilities Committee meets four times monthly in European and American time zones; also open to the public.

“Une leçon clinique à la Salpêtrière” 1887 André Brouillet
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.
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,

The American National Standards Institute — the Global Secretariat for ISO — does not provide content management systems for its US Technical Advisory Groups. Because of the nascent committee, inspired by the work of Lee Webster at the University of Texas Medical Branch needed a content management system, we have been managing content on a Google Site facility on a University of Michigan host since 2014.Earlier this spring, the University of Michigan began upgrading its Google Sites facility which requires us to offload existing content onto the new facility before the end of June. That process is happening now. Because of this it is unwise for us to open the content library for this committee publicly. Respecting copyright, confidentiality of ISO and the US Technical Advisory Group we protect most recent content in the link below and invite anyone to click in any day at 15:00 (16:00) UTC.

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:
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.
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.
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.
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.
The 2020 National Electrical Code (NEC) contains significant revisions to Article 625 Electric Vehicle Power Transfer Systems. Free access to this information is linked below:
Mighty spirited debate. Wireless charging from in-ground facilities employing magnetic resonance are noteworthy. Other Relevant Articles:
Article 240: Overcurrent Protection: This article includes requirements for overcurrent protection devices that could be relevant for EV charging systems.
Article 210: Branch Circuits: General requirements for branch circuits, which can include circuits dedicated to EVSE.
Article 220: Load Calculations: Guidelines for calculating the electrical load for EVSE installations.
Article 230: Services: General requirements for electrical service installations, which can be relevant for EVSE.
Article 250: Grounding and Bonding: Requirements for grounding and bonding, which are critical for safety in EVSE installations.
Technical committees meet November – January to respond. In the intervening time it is helpful break down the ideas that were in play last cycle. The links below provide the access point:
We find a fair amount of administrative and harmonization action; fairly common in any revision cycle. We have taken an interest in a few specific concepts that track in academic research construction industry literature:
Correlation with Underwriters Laboratory product standards
Bi-Directional Charging & Demand Response
Connection to interactive power sources
As a wiring safety installation code — with a large installer and inspection constituency — the NEC is usually the starting point for designing the power chain to electric vehicles. There is close coupling between the NEC and product conformance organizations identified by NIST as Nationally Recognized Testing Laboratories; the subject of a separate post.

After the First Draft is released June 28th public comment is receivable until August 19th.
We typically do not duplicate the work of the 10’s of thousands of National Electrical Code instructors who will be fanning out across the nation to host training sessions for electrical professionals whose license requires mandatory continuing education. That space has been a crowded space for decades. Instead we co-host “transcript reading” sessions with the IEEE Education & Healthcare Facilities Committee to sort through specifics of the 2020 NEC and to develop some of the ideas that ran through 2020 proposals but did not make it to final ballot and which we are likely to see on the docket of the 2023 NEC revision. That committee meets online 4 times monthly. We also include Article 625 on the standing agenda of our Mobility colloquium; open to everyone. See our CALENDAR for the next online meeting

“Benjamin Franklin Drawing Electricity from the Sky” 1816 Benjamin West
Benjamin Franklin conducted his famous experiment with lightning on June 10, 1752.
He used a kite and a key to demonstrate that lightning was a form of electricity.
This experiment marked an important milestone in understanding the nature of electricity
and laid the foundation for the development of lightning rods and other lightning protection systems.
Seasonal extreme weather patterns in the United States, resulting in damages to education facilities and delays in outdoor athletic events — track meets; lacrosse games, swimming pool closures and the like — inspire a revisit of the relevant standards for the systems that contribute to safety from injury and physical damage to buildings: NFPA 780 Standard for the Installation of Lightning Protection Systems
This document shall cover traditional lightning protection system installation requirements for the following: (1) Ordinary structures (2) Miscellaneous structures and special occupancies (3) Heavy-duty stacks (4) Structures containing flammable vapors, flammable gases, or liquids with flammable vapors (5) Structures housing explosive materials (6) Wind turbines (7) Watercraft (8) Airfield lighting circuits (9) Solar arrays
This document shall address lightning protection of the structure but not the equipment or installation requirements for electric generating, transmission, and distribution systems except as given in Chapter 9 and Chapter 12.
(Electric generating facilities whose primary purpose is to generate electric power are excluded from this standard with regard to generation, transmission, and distribution of power. Most electrical utilities have standards covering the protection of their facilities and equipment. Installations not directly related to those areas and structures housing such installations can be protected against lightning by the provisions of this standard.)
This document shall not cover lightning protection system installation requirements for early streamer emission systems or charge dissipation systems.
“Down conductors” must be at least #2 AWG copper (0 AWG aluminum) for Class I materials in structures less than 75-ft in height
“Down conductors: must be at least 00 AWG copper (0000 AWG aluminum) for Class II Materials in structures greater than 75-ft in height.
Related grounding and bonding requirements appears in Chapters 2 and Chapter 3 of NFPA 70 National Electrical Code. This standard does not establish evacuation criteria.

The current edition is dated 2023 and, from the transcripts, you can observe concern about solar power and early emission streamer technologies tracking through the committee decision making. Education communities have significant activity in wide-open spaces; hence our attention to technical specifics.
Public input on the 2026 revision is receivable until 1 June 2023.
We always encourage our colleagues to key in their own ideas into the NFPA public input facility (CLICK HERE). We maintain NFPA 780 on our Power colloquia which collaborates with IEEE four times monthly in European and American time zones. See our CALENDAR for the next online meeting; open to everyone.
Lightning flash density – 12 hourly averages over the year (NASA OTD/LIS) This shows that lightning is much more frequent in summer than in winter, and from noon to midnight compared to midnight to noon.

Didn't really plan for all possibilities, did they. 🤓
Churches and chapels are more susceptible to lightning damage due to their height and design. Consider:
Height: Taller structures are more likely to be struck by lightning because they are closer to the cloud base where lightning originates.
Location: If a church or chapel is situated in an area with frequent thunderstorms, it will have a higher likelihood of being struck by lightning.
Construction Materials: The materials used in the construction of the building can affect its vulnerability. Metal structures, for instance, can conduct lightning strikes more readily than non-metallic materials.
Proximity to Other Structures: If the church or chapel is located near other taller structures like trees, utility poles, or buildings, it could increase the chances of lightning seeking a path through these objects before reaching the building.
Lightning Protection Systems: Installing lightning rods and other lightning protection systems can help to divert lightning strikes away from the structure, reducing the risk of damage.
Maintenance: Regular maintenance of lightning protection systems is essential to ensure their effectiveness. Neglecting maintenance could result in increased susceptibility to lightning damage.
Historical Significance: Older buildings might lack modern lightning protection systems, making them more vulnerable to lightning strikes.
The risk can be mitigated by proper design, installation of lightning protection systems, and regular maintenance.
“…The solar panels will populate the gothic chapel roof, producing an approximate 105,000 kWh of energy a year – enough to run the chapel’s electricity, and saving around £20,000 in energy bills per year. The college confirmed that any excess energy would be sold off to the national grid.
Solar panels perform better when listening to music:
A 2013 study by researchers at Imperial College London and Queen Mary University of London showed that solar panels actually work better when exposed to music, of multiple genres. Scientists at the university proved that when exposed to high pitched sounds, like those found in rock and pop music, the solar cells’ power output increased by up to 40 percent. Classical music was also found to increase the solar cells’ energy production, but slightly less so than rock and pop, as it generally plays at a lower pitch than pop and rock. Whether they know it or not, British band Coldplay are just one of the artists benefitting from this research. During their 2021 tour, they installed solar photovoltaic panels in the build-up to each show, “behind the stage, around the stadium and where possible in the outer concourses”…
To determine how much electrical power and lighting 12 kilowatts (kW) will provide for an educational facility, we need to consider the following factors:
Power Distribution: How the 12 kW will be distributed across different electrical needs such as lighting, computers, HVAC (heating, ventilation, and air conditioning), and other equipment.
Lighting Requirements: The specific lighting requirements per square foot or room, which can vary based on the type of facility (classrooms, libraries, laboratories, etc.).
Efficiency of Lighting: The type of lighting used (e.g., LED, fluorescent, incandescent) as this affects the power consumption and lighting output.
We start with lighting.
Lighting Efficiency:
LED lights are highly efficient, typically around 100 lumens per watt.
Fluorescent lights are less efficient, around 60-70 lumens per watt.
Lighting Power Calculation:
12 kW (12,000 watts) of LED lighting at 100 lumens per watt would provide: 12,000 watts×100 lumens/watt=1,200,000 lumens
Illumination Requirements:
Classroom: Approximately 300-500 lux (lumens per square meter).
Library or laboratory: Approximately 500-750 lux.
Area Coverage:
If we target 500 lux (which is 500 lumens per square meter), we can calculate the area covered by the lighting: (1,200,000 lumens)/ 500 lux=2,400 square meters
Now we need to allocate power to other loads.
Lighting: Assuming 50% of the 12 kW goes to lighting:
Lighting Power: 6 kW (6,000 watts)
Using the previous calculation: 6,000 watts×100 lumens/watt=600,000 lumens
Area Coverage for lighting (at 500 lux): (600,000 lumens)/500 lux=1,200 square meters
Other Electrical Needs:
Computers and equipment: Typically, a computer lab might use around 100 watts per computer.
HVAC: This can vary widely, but let’s assume 4 kW is allocated for HVAC and other systems.
Breakdown:
Lighting: 6 kW
Computers/Equipment: 2 kW (e.g., 20 computers at 100 watts each)
HVAC and other systems: 4 kW
Summary
Lighting: 12 kW can provide efficient LED lighting for approximately 1,200 square meters at 500 lux.
General Use: When distributed, 12 kW can cover lighting, a computer lab with 20 computers, and basic HVAC needs for a small to medium-sized educational facility.
The exact capacity will vary based on specific facility needs and equipment efficiency.
Technical Committee 82 of the International Electrotechnical Commission is charged with preparing international standards for the full length of the solar energy power chain The span of the power chain includes the light input, the cell itself, and the fittings and accessories to the end use (utilization) equipment.
The USNA/IEC and participates in its standards development processes; typically collaborating with global research and application engineers in the IEEE Industrial Applications Society and the IEEE Power and Energy Society. To advance its agenda for lower #TotalCostofOwnership for US real asset executives and facility managers Standards Michigan also collaborates closely with subject matter experts who contribute to, and draw from, the knowledge base in the IEEE Education and Healthcare Facilities Committee (E&H).
The IEC permits public commenting on its draft standards; though you will need to establish login credentials:
Your comments will be reviewed by the IEC National Committee of the country you live in, which can decide to propose them as national input for the final draft of the IEC International Standard. This approach makes it easier for individual nations to participate in IEC standards development processes because the resources that national standards bodies need to administer participation resides in Geneva and is managed there.

We collaborate with the IEEE Education & Healthcare Facilities Committee which has its own platform to tracking commenting opportunities:
As of this posting, no interoperability redlines have been released for public consultation. In large measure, IEC titles contribute to a level playing field among multi-national electrical equipment manufacturers so we should not be surprised that there are no redlines to review. When they are released we place them on the agenda of the IEEE E&H Committee which meets 4 times monthly in European and American time zones.
