Pathway Illumination

“Nighthawks” 1942 Edward Hopper

The Illumination Engineering Society is 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:

IES LP-12 Lighting Practice: IoT Connected Lighting

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.

IES Standards in Public Review

A few other technical committees relevant to educational communities should be identified, though we will sort through the standards setting activity in separate posts:

Edu-Lib-Ofc Lighting Committee

Outdoor Environmental Lighting Committee

Outdoor Public Spaces Committee

Roadway Lighting Committee  (Many large research universities own miles of roads)

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.

These are generally downloads.  We are happy to pick through the changes to the Electrical stack depending upon interest.

All fifty United States have their own “signature” disaster with which to reckon; some more than others.   California has earthquakes, Florida has hurricanes, Missouri has floods; and so on,  Life and property loss are preventable; but losses will persist because technical solutions notwithstanding, culture determines human behavior.  It is impossible to be alive and safe.

FM Global is one of several organizations that curate privately developed consensus products that set the standard of care for many industries; education communities among them.  These standards contribute to the reduction in the risk of property loss due to fire, weather conditions, and failure of electrical or mechanical equipment.  They incorporate nearly 200 years of property loss experience, research and engineering results, as well as input from consensus standards committees, equipment manufacturers and others.

If you want FMGlobal as your insurance carrier, or to supplement your organization’s self-insurance program, then you will likely be assigned an FMGlobal conformity professional.

A scan of its list data sheets indicate a number of noteworthy updates of documents establishing minimum requirements for safety technologies common in education facilities:

Technical Reports Supporting Code Change

Note that the bulk of the safety concepts in the foregoing titles incorporate by reference the safety concepts that cross our radar every day   FM Global provides direct access to the full span of its documents at this link:

To respond to calls for public consultation you will need to set up (free) access credentials.

We keep FMGlobal titles — and the literature of other property insurers involved in standards setting — on the standing agenda of our Risk, Snow and Prometheus colloquia.  See our CALENDAR for the next meeting.

Electrical installations and Protection Against Electric Shock

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.

TC 64 Strategic Business Plan

The scope of IEC 60364 is reproduced below:

– 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.

Date & Time: Representations For Information Interchange

“A Philosopher Lecturing on the Orrery” | Joseph Wright (1766)

Most nations follow the day/month/year format (07/01/19 for January 7, 2019, for example), but the United States adheres to its own format of month/day/year (1/7/19 or 1/7/2019).   The potential for misinterpreting dates across national boundaries is the logic for ISO 8601:2019 – Data Elements And Interchange Formats – Information Interchange – Representation Of Dates And Times, the ISO format for dates represents year, month, and day from the largest unit to the smallest, most specific unit of time.  The ISO date format is the date format used in SQL and is the default date setting on many computers.

Baseball Lighting

The College World Series begins this weekend in Omaha between Louisiana State University and Coastal Carolina.

 

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.

“Baseball at Night” | Morris Kantor (1934)

 

 

 

“Baseball is ninety percent mental

and the other half is physical.”

– Yogi Berra

 

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:

NCAA Best Lighting Practices

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.

Rightsizing Electrical Power Systems

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.”

NFPA Electrical Division knows it, too.

Rightsizing Commercial Electrical Power Systems: Review of a New Exception in NEC Section 220.12

Michael A. Anthony – James R. Harvey

University of Michigan, Ann Arbor

Thomas L. Harman

University of Houston, Clear Lake, Texas

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.
