Baseball is a pastoral game and lighting changed the experience of it. Since a baseball is less than 3-inches in diameter and routinely travels 400 feet at 100 miles per hour, illumination design must have outfielders in mind as well as other players and spectators.
After athletic facility 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 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 the spring baseball season the document linked below provides guidance for illumination designers, contractors 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 cover the objectives of the energy conservation advocates in separate posts; notably advocates using the International Code Council and the ASHRAE suite to advance their agenda to press boxes and the entire baseball experience (interior and exterior) site in separate posts.
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 Sport colloquium. 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.

Elevators rely on electricity to function, and when there’s a power outage, the main source of power is disrupted. Modern elevators often have backup power systems, such as generators or battery packs, to lower the cab to the nearest floor and open the doors, but these systems may not work optimally, or be connected to all elevators or may not exist in older or less well-maintained buildings.
Today we start with getting the source of power right; leaving complicating factors such as alarms, reset and restart sequences. NFPA 110 is the parent standard which references NFPA 70.

Should every campus building generate its own power? Sustainability workgroups are vulnerable to speculative hype about net-zero buildings and microgrids. We remind sustainability trendsniffers that the central feature of a distributed energy resource–the eyesore known as the university steam plant–delivers most of the economic benefit of a microgrid. [Comments on Second Draft due April 29th] #StandardsMassachusetts

We have been following the developmental trajectory of a new NFPA regulatory product — NFPA 855 Standard for the Installation of Stationary Energy Storage Systems — a document with ambitions to formalize the fire safety landscape of the central feature of campus microgrids by setting criteria for minimizing the hazards associated with energy storage systems.
The fire safety of electric vehicles and the companion storage units for solar and wind power systems has been elevated in recent years with incidents with high public visibility. The education industry needs to contribute ideas and data to what we call the emergent #SmartCampus;an electrotechnical transformation — both as a provider of new knowledge and as a user of the new knowledge.
Transcripts of technical deliberation are linked below:
Comment on the 2026 revision received by March 27, 2025 will be heard at the NFPA June 2025 Expo through NFPA’s NITMAM process.
University of Michigan | Average daily electrical load across all Ann Arbor campuses is on the order of 100 megawatts
A fair question to ask: “How is NFPA 855 going to establish the standard of care any better than the standard of care discovered and promulgated in the NFPA 70-series and the often-paired documents NFPA 110 and NFPA 111?” (As you read the transcript of the proceedings you can see the committee tip-toeing around prospective overlaps and conflicts; never a first choice).
Suffice to say, the NFPA Standards Council has due process requirements for new committee projects and, obviously, that criteria has been met. Market demand presents an opportunity to assemble a new committee with fresh, with new voices funded by a fresh set of stakeholders who, because they are more accustomed to advocacy in open-source and consortia standards development platforms, might have not been involved in the more rigorous standards development processes of ANSI accredited standards developing organizations — specifically the NFPA, whose members are usually found at the top of organization charts in state and local jurisdictions. For example we find UBER — the ride sharing company — on the technical committee. We find another voice from Tesla Motors. These companies are centered in an industry that does not have the tradition of leading practice discovery and promulgation that the building industry has had for the better part of two hundred years.
Our interest in this standard lies on both sides of the education industry — i.e. the academic research side and the business side. For all practical purposes, the most credible, multi-dimensional and effective voice for lowering #TotalCostofOwnership for the emergent smart campus is found in the tenure of Standards Michigan and its collaboration with IEEE Education & Healthcare Facilities Committee (E&H). You may join us sorting through the technical, economic and legal particulars and day at 11 AM Eastern time. The IEEE E&H Committee meets online every other Tuesday in European and American time zones; the next meeting on March 26th. All meetings are open to the public.

You are encouraged to communicate directly with Brian O’Connor, the NFPA Staff Liaison for specific questions. We have some of the answers but Brian is likely to have all of them. CLICK HERE for the NFPA Directory. Additionally, NFPA will be hosting its Annual Conference & Expo, June 17-20 in San Antonio, Texas; usually an auspicious time for meeting NFPA staff working on this, and other projects.
The prospect of installing of energy storage technologies at every campus building — or groups of buildings, or in regions — is clearly transformational if the education facilities industry somehow manages to find a way to drive the cost of operating and maintaining many energy storage technologies lower than the cost of operating and maintaining a single campus distributed energy resource. The education facility industry will have to train a new cadre of microgrid technology specialists who must be comfortable working at ampere and voltage ranges on both sides of the decimal point that separates power engineers from control engineers. And, of course, dynamic utility pricing (set by state regulatory agencies) will continue to be the most significant independent control variable.
Finding a way to make all this hang together is the legitimate work of the academic research side of the university. We find that sustainability workgroups (and elected governing bodies) in the education industry are vulnerable to out-sized claims about microgrids and distributed energy resources; both trendy terms of art for the electrotechnical transformation we call the emergent #SmartCampus.
We remind sustainability trendsniffers that the central feature of a distributed energy resource — the eyesore known as the university steam plant — bears most of the characteristics of a microgrid. In the videoclip linked below a respected voice from Ohio State University provides enlightenment on this point; even as he contributes to the discovery stream with a study unit.

First Draft Meetings: January 15-26, 2024 in Charleston, South Carolina
Electrical meter billing standards are generally regulated at the state or local level, with guidelines provided by public utility commissions or similar regulatory bodies. These tariff sheets are among the oldest in the world. There are some common standards for billing and metering practices, including:
Meter Types: There are various types of meters used to measure electricity consumption, including analog (mechanical) meters, digital meters, and smart meters. Smart meters are becoming more common and allow for more accurate and real-time billing.
Billing Methodology:
Residential Rates: Most residential customers are billed based on kilowatt-hours (kWh) of electricity used, which is the standard unit of energy.
Demand Charges: Some commercial and industrial customers are also subject to demand charges, which are based on the peak demand (the highest amount of power drawn at any one point during the billing period).
Time-of-Use Rates: Some utilities offer time-of-use (TOU) pricing, where electricity costs vary depending on the time of day or season. For example, electricity may be cheaper during off-peak hours and more expensive during peak hours.
Meter Reading and Billing Cycle:
Monthly Billing: Typically, customers receive a bill once a month, based on the reading of the electricity meter.
Estimation: If a meter reading is not available, some utilities may estimate usage based on historical patterns or average usage.
Smart Meter Readings: With smart meters, some utilities can provide daily or even hourly usage data, leading to more precise billing.
Meter Standards: The standards for electrical meters, including their accuracy and certification, are set by national organizations like the National Institute of Standards and Technology (NIST) and the American National Standards Institute (ANSI). Meters must meet these standards to ensure they are accurate and reliable.
Utility Commission Regulations: Each state has a utility commission (such as the California Public Utilities Commission, the Texas Public Utility Commission, etc.) that regulates the rates and billing practices of electricity providers. These commissions ensure that rates are fair and that utilities follow proper procedures for meter readings, billing cycles, and customer service
Large University “Utilities”. Large colleges and universities that generate and distribute some or all of their electric power consumption have developed practices to distribute the cost of electricity supply to buildings. We will cover comparative utility billing practices in a dedicated colloquium sometime in 2025.
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.”
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.
Today we examine relatively recent transactions in electrotechnologies — power, information and communication technology — that are present (and usually required) in patient care settings. At a patient’s bedside in a hospital or healthcare setting, various electrical loads or devices may be present to provide medical care, monitoring, and comfort. Some of the common electrical loads found at a patient’s bedside include:
Hospital Bed: Electric hospital beds allow for adjustments in height, head position, and leg position to provide patient comfort and facilitate medical procedures.
Patient Monitor: These monitors display vital signs such as heart rate, blood pressure, oxygen saturation, and respiratory rate, helping healthcare professionals keep track of the patient’s condition.
Infusion Pumps: These devices administer medications, fluids, and nutrients intravenously at a controlled rate.
Ventilators: Mechanical ventilators provide respiratory support to patients who have difficulty breathing on their own.
Pulse Oximeter: This non-invasive device measures the oxygen saturation level in the patient’s blood.
Electrocardiogram (ECG/EKG) Machine: It records the electrical activity of the heart and is used to diagnose cardiac conditions.
Enteral Feeding Pump: Used to deliver liquid nutrition to patients who cannot take food by mouth.
Suction Machine: It assists in removing secretions from the patient’s airway.
IV Poles: To hold and support intravenous fluid bags and tubing.
Warming Devices: Devices like warming blankets or warm air blowers are used to maintain the patient’s body temperature during surgery or recovery.
Patient Call Button: A simple push-button that allows patients to call for assistance from the nursing staff.
Overbed Tables: A movable table that allows patients to eat, read, or use personal items comfortably.
Reading Lights: Bedside lights that allow patients to read or perform tasks without disturbing others.
Television and Entertainment Devices: To provide entertainment and alleviate boredom during the patient’s stay.
Charging Outlets: Electrical outlets to charge personal electronic devices like smartphones, tablets, and laptops.
It’s important to note that the specific devices and equipment present at a patient’s bedside may vary depending on the level of care required and the hospital’s equipment standards. Additionally, strict safety measures and electrical grounding are essential to ensure patient safety when using electrical devices in a healthcare setting.
We have been tracking the back-and-forth on proposals, considerations, adoption and rejections in the 3-year revision cycles of the 2023 National Electrical Code and the2021 Healthcare Facilities Code. We will use the documents linked below as a starting point for discussion; and possible action:
There are many other organizations involved in this very large domain — about 20 percent of the US Gross Domestic Product.
Ahead of the September 7th deadline for new proposals for Article 517 for the 2026 National Electrical Code we will examine their influence in other sessions; specifically in our Health 100,200,300 and 400 colloquia. See our CALENDAR for the next online meeting; open to everyone.
