After athletic arena 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 come into play.   The illumination of the competitive venue itself figures heavily into the quality of digital media visual experience and value.

For almost all athletic facilities,  the consensus documents of the Illumination Engineering Society[1], the Institute of Electrical and Electronic Engineers[2][3] provide the first principles for life safety.  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.

The NCAA is not a consensus standard developer but it does have a suite of recommended practice documents for lighting the venues for typical competition and competition that is televised.

International Zoning Code

ANSI Standards Action: February 2, 2024

National Association of County Engineers

The purpose of the code is to establish minimum requirements to provide a reasonable level of health, safety, property protection and welfare by controlling the design, location, use or occupancy of all buildings and structures through the regulated and orderly development of land and land uses within this jurisdiction.

Municipalities usually have specific land use or zoning considerations to accommodate the unique needs and characteristics of college towns:

  1. Mixed-Use Zoning: Cities with colleges and universities often employ mixed-use zoning strategies to encourage a vibrant and diverse urban environment. This zoning approach allows for a combination of residential, commercial, and institutional uses within the same area, fostering a sense of community and facilitating interactions between students, faculty, and residents.
  2. Height and Density Restrictions: Due to the presence of educational institutions, cities may have specific regulations on building height and density to ensure compatibility with the surrounding neighborhoods and maintain the character of the area. These restrictions help balance the need for development with the preservation of the existing urban fabric.
  3. Student Housing: Cities with colleges and universities may have regulations or guidelines for student housing to ensure an adequate supply of affordable and safe accommodations for students. This can
    include requirements for minimum bedroom sizes, occupancy limits, and proximity to campus.
  4. Parking and Transportation: Given the concentration of students, faculty, and staff, parking and transportation considerations are crucial. Cities may require educational institutions to provide parking facilities or implement transportation demand management strategies, such as promoting public transit use, cycling infrastructure, and pedestrian-friendly designs.
  5. Community Engagement: Some cities encourage colleges and universities to engage with the local community through formalized agreements or community benefit plans. These may include commitments to support local businesses, contribute to neighborhood improvement projects, or provide educational and cultural resources to residents.

  1. Reed v. Town of Gilbert (2015): This Supreme Court case involved a challenge to the town of Gilbert, Arizona’s sign code, which regulated the size, location, and duration of signs based on their content. The court held that the sign code was a content-based restriction on speech and therefore subject to strict scrutiny.
  2. City of Ladue v. Gilleo (1994): In this Supreme Court case, the court struck down a municipal ordinance that banned the display of signs on residential property, except for signs that fell within specific exemptions. The court held that the ban was an unconstitutional restriction on the freedom of speech.
  3. Metromedia, Inc. v. San Diego (1981): This Supreme Court case involved a challenge to a San Diego ordinance that banned off-premises advertising signs while allowing on-premises signs. The court held that the ordinance was an unconstitutional restriction on free speech, as it discriminated against certain types of speech.
  4. City of Ladue v. Center for the Study of Responsive Law, Inc. (1980): In this Supreme Court case, the court upheld a municipal ordinance that prohibited the display of signs on public property, but only if the signs were posted for longer than 10 days. The court held that the ordinance was a valid time, place, and manner restriction on speech.
  5. City of Boerne v. Flores (1997): This Supreme Court case involved a challenge to a municipal sign code that regulated the size, location, and content of signs in the city. The court held that the sign code violated the Religious Freedom Restoration Act, as it burdened the exercise of religion without a compelling government interest.

 

Animal Safety

“One of the Family” 1880 | Frederick George Cotman

NFPA 150 Fire and Life Safety in Animal Housing Facilities Code has entered its s025 revision cycle.   Many education communities are responsible for animal safety in academic units, research enterprises. museums and even — as in the United Kingdom — large farm animals that wander freely on campus with students, faculty and staff.  The number of colleges and universities that permit students to live with their pets has expanded; and with it the responsibilities of university administration.

From the document scope:

This standard shall provide the minimum requirements for the design, construction, fire protection, and classification of animal housing facilities.  The requirements of NFPA 150 recognize the following fundamental principles:

(1) Animals are sentient beings with a value greater than that of simple property.

(2) Animals, both domesticated and feral, lack the ability of self-preservation when housed in buildings and other structures.

(3) Current building, fire, and life safety codes do not address the life safety of the animal occupants. The requirements found in NFPA 150 are written with the intention that animal housing facilities will continue to be designed, constructed, and maintained in accordance with the applicable building, fire, and life safety codes.

The requirements herein are not intended to replace or rewrite the basic requirements for the human occupants. Instead, NFPA 150 provides additional minimum requirements for the protection of the animal occupants and the human occupants who interact with those animals in these facilities.

We provide the transcript of the back-and-forth on the current 2022 edition to inform how education communities can contribute to the improvement of this title; a subject that stirs deep feelings about animal safety in research enterprises.

NFPA 150 First Draft Agenda

NFPA 150 Second Draft Report

Public comment on the Second Draft of the 2025 Edition will be received until March 27, 2024.   

We have been advocating risk-informed animal safety concepts in this document since the 2013 Edition and have found that it is nearly impossible to overestimate the sensitivity of educational communities to the life safety of animals — either for agriculture or medical research.

We maintain the entire NFPA catalog on the standing agenda of our Prometheus colloquia.  See our CALENDAR for the next online meeting; open to everyone.

Stray Voltage: Sources and Solutions

Stray Voltage: Sources and Solutions

Truman C. Surbrook – Norman D. Reese – Angela M. Kehrle

 

Abstract.  Stray voltage is caused by voltage drop and ground faults and may have its origin on the primary electrical distribution system or on the customer’s secondary electrical system. The rms value of the neutral-to-earth voltage along a primary distribution line may be at a value of zero some distance from the substation depending on the condition of the conductor resistances, grounding resistances, and the amount of load. Neutral-to-earth resistance is not the cause of stray voltage; however, the value of this resistance to earth at a particular location will affect the level of stray voltage. A four-wire single-phase feeder system supplying farm buildings from a single metering point is effective in preventing on-farm secondary neutral voltage drop, provided the four-wire system is extended to all farm loads, and provided no high-magnitude ground faults are present. Isolation of the primary and secondary neutral systems at the distribution transformer is effective in preventing off-farm sources from entering the customer’s system. This separation may be accomplished using a number of commercially available devices.

Python can be used to control building automation systems. Building automation systems are typically used to control various systems within a building, such as heating, ventilation, air conditioning, lighting, security, and more. Python can be used to control these systems by interacting with the control systems through the building’s network or other interfaces.

There are several Python libraries available that can be used for building automation, including PyVISA, which is used to communicate with instrumentation and control systems, and PyModbus, which is used to communicate with Modbus devices commonly used in building automation systems. Python can also be used to develop custom applications and scripts to automate building systems, such as scheduling temperature setpoints, turning on and off lights, and adjusting ventilation systems based on occupancy or other variables. Overall, Python’s flexibility and versatility make it well-suited for use in building automation systems.
