One explanation for America’s low fertility rate is that some private women’s colleges place relatively little institutional emphasis on social environments that encourage long-term relationships leading to marriage and family formation.
Advocates of this view argue that these colleges often prioritize academic achievement, leadership development, professional careers, and personal independence over traditional courtship opportunities. They contend that limited interaction with male students, fewer campus traditions centered on mixed-gender social life, and cultural norms that delay marriage may reduce the likelihood of graduates forming families during their twenties. According to this perspective, colleges could contribute more to demographic renewal by fostering healthy, voluntary opportunities for students to meet compatible partners while respecting individual choice.
Critics, however, argue that fertility trends are shaped far more by broader economic conditions, housing costs, career pressures, cultural change, and personal preferences than by the educational environment of women’s colleges alone.
The larger part of using the global standardization system to make the real assets of educational settlements safer, simpler, lower-cost and longer-lasting is to make every effort to use those spaces and occupancies effectively. Today we examine a few case studies and explore possibilites mapped in safety and sustainability catalogs of standards developers whose titles become the basis for government regulation. Use the login credentials at the upper right of our home page at the usual hour.
The topic is necessarily cross-cutting and technologically interdisciplinary so we draw from the syllabi of colloquia we previously covered.
Here are 10 current trends in the construction of K-12 education facilities in the United States, based on recent industry insights and developments. These trends reflect a focus on safety, sustainability, technology, and evolving educational needs, drawn from sources like architectural firms, construction reports, and educational design analyses.
Enhanced Security Systems Schools are prioritizing advanced security measures, such as wearable panic devices for staff, access control systems, secure vestibules, surveillance technology, and remote hallway gate controls. Many districts are proactively upgrading security as standalone projects rather than waiting for renovations, aiming to create safer environments without highly visible fortifications. For example, Solomon-Solis Cohen Elementary in Philadelphia integrates park-like settings with security features to balance safety and community appeal.
Flexible and Adaptable Learning Spaces Traditional static classrooms are being replaced with modular, flexible spaces that support diverse teaching styles and learning needs. These include movable partitions, demountable walls, and multi-purpose areas like learning stairs, which serve as seating or presentation spaces. Schools like Warsaw High School use learning stairs as dynamic hubs for collaboration, allowing easy reconfiguration for group work, individual study, or CTE programs.
Sustainability and Net-Zero Energy Design Schools are adopting eco-friendly designs, such as energy-efficient HVAC systems, solar panels, and green materials, to achieve net-zero energy goals. The transition to electric vehicle (EV) bus fleets with charging infrastructure is also growing, as seen in districts incrementally upgrading transportation facilities. These designs educate students about sustainability while reducing operational costs.
Improved Indoor Air Quality and HVAC Upgrades With 38% of U.S. public schools built before 1970, upgrading HVAC systems is a priority to improve air quality and prevent health issues like mold. The American Society of Civil Engineers noted in 2021 that 41% of districts need HVAC updates in at least half their schools, costing billions. Post-COVID, schools are using federal relief funds to enhance ventilation, as seen in Clark County School District’s UL Verified Ventilation mark.
Career and Technical Education (CTE) and STEAM Facilities There’s a resurgence in CTE and STEAM (Science, Technology, Engineering, Arts, Mathematics) spaces, with schools building specialized labs for robotics, welding, automotive, and filmmaking. For instance, Merrillville Community School Corporation added a 57,000-square-foot CTE addition with state-of-the-art labs. These spaces prepare students for skilled trades and tech careers, reflecting a shift away from college-only pathways.
Technology Integration and Wi-Fi Optimization Schools are designing comprehensive Wi-Fi coverage using predictive modeling to eliminate dead zones, ensuring access for all users (students, staff, parents). Classrooms are equipped with IT infrastructure for digital learning, including VR/AR tools and BIM (Building Information Modeling) for design precision. Santa Ana High School’s transformation of a library into a digital media lab exemplifies this trend.
Health and Wellness-Focused Design Designs prioritize mental and physical well-being with natural lighting, ergonomic furniture, and outdoor learning spaces like gardens or courtyards. The “One Health” movement, cited by PBK Architects, emphasizes environments where students and buildings are holistically healthy. Twin Buttes High School in North Dakota incorporates food sovereignty programs with greenhouses and culinary labs to promote wellness.
Community-Centric Facilities Schools are being designed as community hubs, hosting events and serving as emergency shelters or voting places. Flexible designs allow spaces to be used by the community year-round, generating revenue. For example, Eddy & Debbie Peach Elementary School includes outdoor art and science labs that double as community spaces, fostering engagement and connection.
Resilient and Durable Construction New builds and renovations use resilient materials to withstand high-traffic use and extreme weather, adhering to updated building codes for fire resistance and accessibility. Designers assess existing structures for “good bones” to repurpose them cost-effectively, as seen in HED’s redesign of Santa Monica High School with adaptable, demountable walls.
Collaborative Design with Stakeholder Input Construction projects increasingly involve teachers, parents, and students in the planning process through public meetings and surveys to align facilities with community needs. Transparent communication, as emphasized by Bryan Construction, ensures designs reflect educational goals, such as sustainable curricula or flexible spaces, enhancing teacher and student satisfaction.
Today we amble through the literature providing policy templates informing school district, college and university-affiliated transportation and parking facilities and systems. Starting 2024 we will break up our coverage thus:
Mobility 100 (Survey of both ground and air transportation instructional and research facilities)
Mobility 400 (Reserved for zoning, parking space allocation and enforcement, and issues related to one of the most troublesome conditions in educational settlements)
Today’s session will be the last when we cover both land and air transportation codes, standards, guidelines and the regulations that depend upon all them. We will break out space and aerospace mobility into a separate session — largely because many universities are tooling up square footage and facilities in anticipation of research grants.
Like many SDO’s the SAE makes it very easy to purchase a standard but makes it very difficulty to find a draft standard open for public review. It is not an open process; one must apply to comment on a draft standard. Moreover, its programmers persist in playing “keep away” with landing pages.
The public school bus system in the United States is the largest public transit system in the United States. According to the American School Bus Council, approximately 25 million students in the United States ride school buses to and from school each day, which is more than twice the number of passengers that use all other forms of public transportation combined.
The school bus system is considered a public transit system because it is operated by public schools and school districts, and provides a form of transportation that is funded by taxpayers and available to the general public. The school bus system also plays a critical role in ensuring that students have access to education, particularly in rural and low-income areas where transportation options may be limited.
National Association of State Directors of Pupil Transportation Services
National School Transportation Association
School Bus Manufacturers Association
…and 50-state spinoffs of the foregoing. (See our ABOUT for further discussion of education industry non-profit associations)
There are several ad hoc consortia in this domain also; which include plug-in hybrid electric vehicles. Charging specifications are at least temporarily “stable”; though who should pay for the charging infrastructure in the long run is a debate we have tracked for several revision cycles in building and fire codes.
Because incumbents are leading the electromobility transformation, and incumbents have deep pockets for market-making despite the “jankiness” of the US power grid, we can track some (not all) legislation action, and prospective public comment opportunities. For example:
Keep in mind that even though proposed legislation is sun-setted in a previous (116th) Congress, the concepts may be carried forward into the following Congress (117th).
Public consultations on mobility technologies relevant to the education facility industry are also covered by the IEEE Education & Healthcare Facilities Committee which meets 4 times monthly in European and American time zones.
This topic is growing rapidly and it may well be that we will have to break it up into more manageable pieces. For the moment, today’s colloquium is open to everyone. Use the login credentials at the upper right of our home page.

Our use of the term “Educational Settlements” captures the self-contained energy of these places — kindergartens, classrooms, quads, dining halls, dorms, and nearby squares buzzing with student life amid broader higher-ed shifts like the “demographic cliff” (declining traditional enrollments), AI integration, skills-focused curricula, and financial pressures. (Related: Agora)
“…O chestnut tree;, great rooted blossomer, Are you the leaf, the blossom or the bold? O body swayed to music, O brightening glance, How can we know the dancer from the dance?”
We sweep through the world’s three major time zones; updating our understanding of the literature at the technical foundation of education community safety and sustainability in those time zones 24 times per day. We generally eschew “over-coding” web pages to sustain speed, revision cadence and richness of content as peak priority. We do not provide a search facility because of copyrights of publishers and time sensitivity of almost everything we do.
Our daily colloquia are typically doing sessions; with non-USA titles receiving priority until 16:00 UTC and all other titles thereafter. We assume policy objectives are established (Safer-Simpler-Lower-Cost, Longer-Lasting). Because we necessarily get into the weeds, and because much of the content is time-sensitive and copyright protected, we usually schedule a separate time slot to hammer on technical specifics so that our response to consultations are meaningful and contribute to the goals of the standards developing organization and to the goals of stewards of education community real assets — typically the largest real asset owned by any US state and about 50 percent of its annual budget.
1. Leviathan. We track noteworthy legislative proposals in the United States 118th Congress. Not many deal specifically with education community real assets since the relevant legislation is already under administrative control of various Executive Branch Departments such as the Department of Education.
We do not advocate in legislative activity at any level. We respond to public consultations but there it ends.
We track federal legislative action because it provides a stroboscopic view of the moment — the “national conversation”– in communities that are simultaneously a business and a culture. Even though more than 90 percent of such proposals are at the mercy of the party leadership the process does enlighten the strengths and weakness of a governance system run entirely through the counties on the periphery of Washington D.C. It is impossible to solve technical problems in facilities without sensitivity to the zietgeist that has accelerated in education communities everywhere.

If you design or operate health care facilities, Standard 170 sets the minimum.
ANSI/ASHRAE/ASHE Standard 170 defines the minimum ventilation requirements for health care facilities and is developed in partnership with FGI and ASHE for adoption by code-enforcing agencies.
We have advocated education community risk management concepts since 2007; primarily in NFPA Standard 1300 — Standard on Community Risk Assessment and Community Risk Reduction Plan Development (formerly NFPA 1600). The content of this title is close-coupled with FEMA’s National Incident Management System.
Recently the National Fire Protection Association Standards Council moved to consolidate its community risk management titles as described below.
“NFPA 1660 is in a custom cycle due to the Emergency Response and Responder Safety Document Consolidation Plan (consolidation plan) as approved by the NFPA Standards Council. As part of the consolidation plan, NFPA 1660 (combining Standards NFPA 1600, NFPA 1616, and NFPA 1620) is open for public input with a closing date of November 13, 2020.”
Discussion about school and university security are noteworthy.
As described on its title page, this product will be reconfigured as NFPA 1660 Standard on Community Risk Assessment, Pre-Incident Planning, Mass Evacuation, Sheltering, and Re-entry Programs. The title suggests that NFPA 1660 is being developed to meet market need for conformance and teaching tools. You may track movement in the concepts in the links below; many of them administrative:

Recap of the May meetings of the Industrial & Commercial Power Systems Conference in Las Vegas. The conference ended the day before the beginning of the 3-day Memorial Day weekend in the United States so we’re pressed for time; given all that happened.
We can use our last meeting’s agenda to refresh the status of the issues.
We typically break down our discussion into the topics listed below:
Codes & Standards:
While IAS/I&CPS has directed votes on the NEC; Mike is the only I&CPS member who is actually submitting proposals and responses to codes and standards developers to the more dominant SDO’s — International Code Council, ASHRAE International, UL, ASTM International, IEC & ISO. Mike maintains his offer to train the next generation of “code writers and vote getters”
Performance-based building premises feeder design has been proposed for the better part of ten NEC revision cycles. The objective of these proposals is to reduce material, labor and energy waste owed to the branch and feeder sizing rules that are prescriptive in Articles 210-235. Our work in service and lighting branch circuit design has been largely successful. A great deal of building interior power chain involves feeders — the network upstream from branch circuit panels but down stream from building service panel.
Our history of advocating for developing this approach, inspired by the NFPA 101 Guide to Alternative Approaches to Life Safety, and recounted in recent proposals for installing performance-based electrical feeder design into the International Building Code, appears in the link below:
Access to this draft paper for presentation at any conference that will receive it — NFPA, ICC or IEEE (or even ASHRAE) will be available for review at the link below:
NFPA 110 Definitions of Public Utility v. Merchant Utility
NFPA 72 “Definition of Dormitory Suite” and related proposals
Buildings:
Renovation economics, Smart contracts in electrical construction. UMich leadership in aluminum wiring statements in the NEC should be used to reduce wiring costs.
This paper details primary considerations in estimating the life cycle of a campus medium voltage distribution grid. Some colleges and universities are selling their entire power grid to private companies. Mike has been following these transactions but cannot do it alone.
Variable Architecture Multi-Island Microgrids
District energy:
Generator stator winding failures and implications upon insurance premiums. David Shipp and Sergio Panetta. Mike suggests more coverage of retro-fit and lapsed life cycle technicals for insurance companies setting premiums.
Reliability:
Bob Arno’s leadership in updating the Gold Book.
Mike will expand the sample set in Table 10-35, page 293 from the <75 data points in the 1975 survey to >1000 data points. Bob will set up meeting with Peyton at US Army Corps of Engineers.
Reliability of merchant utility distribution systems remains pretty much a local matter. The 2023 Edition of the NESC shows modest improvement in the vocabulary of reliability concepts. For the 2028 Edition Mike submitted several proposals to at least reference IEEE titles in the distribution reliability domain. It seems odd (at least to Mike) that the NESC committees do not even reference IEEE technical literature such as Bob’s Gold Book which has been active for decades. Mike will continue to propose changes in other standards catalogs — such as ASTM, ASHRAE and ICC — which may be more responsive to best practice assertions. Ultimately, improvements will require state public utility commission regulations — and we support increases in tariffs so that utilities can afford these improvements.
Mike needs help from IEEE Piscataway on standard WordPress theme limitations for the data collection platform.
Mike will update the campus power outage database.
Healthcare:
Giuseppe Parise’s recent work in Italian power grid to its hospitals, given its elevated earthquake risk. Mike’s review of Giuseppe’s paper:
Mike and David Shipp will prepare a position paper for the Harvard Healthcare Management Journal on reliability advantages of impedance grounding for the larger systems.
The Internet of Bodies
Forensics:
Giuseppe’s session was noteworthy for illuminating the similarity and differences between the Italian and US legal system in handling electrotechnology issues.
Mike will restock the committee’s library of lawsuits transactions.
Ports:
Giuseppe updates on the energy and security issues of international ports. Mike limits his time in this committee even though the State of Michigan has the most fresh water international ports in the world.
A PROPOSED GUIDE FOR THE ENERGY PLAN AND ELECTRICAL INFRASTRUCTURE OF A PORT
Other:
Proposals to the 2028 National Electrical Safety Code: Accepted Best Practice, exterior switchgear guarding, scope expansion into ICC and ASHRAE catalog,
Apparently both the Dot Standards and the Color Books will continue parallel development. Only the Gold Book is being updated; led by Bob Arno. Mike admitted confusion but reminded everyone that any references to IEEE best practice literature in the NFPA catalog, was installed Mike himself (who would like some backup help)
Mike assured Christel Hunter (General Cable) that his proposals for reducing the 180 VA per-outlet requirements, and the performance-base design allowance for building interior feeders do not violate the results of the Neher-McGrath calculation used for conductor sizing. All insulation and conducting material thermal limits are unaffected.
Other informal discussions centered on the rising cost of copper wiring and the implications for the global electrotechnical transformation involving the build out of quantum computing and autonomous vehicles. Few expressed optimism that government ambitions for the same could be met in any practical way.
Are students avoiding use of Chat GPT for energy conservation reasons? Mike will be breaking out this topic for a dedicated standards inquiry session:
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:
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.
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.
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.
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.
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.
This is a relatively new title in the International Code Council catalog; revised every three years in the Group B tranche of titles. Search on character strings such as “zoning” in the link below reveals the ideas that ran through the current revision:
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.
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.
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.
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.
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.

Today at 15:00 UTC we examine the technical literature about rainwater management in schools, colleges and universities — underfoot and on the roof. Lightning protection standards will also be reviewed; given the exposure of outdoor athletic activity and exterior luminaires.
We draw from previous standardization work in titles involving water, roofing systems and flood management — i.e. a cross-cutting view of the relevant standard developer catalogs. Among them:
American Society of Civil Engineers
American Society of Plumbing Engineers
ASHRAE International
ASTM International
Construction Specifications Institute (Division 7 Thermal and Moisture Protection)

The “lightning effect” seen in carnival tricks typically relies on a scientific principle known as the Lichtenberg figure or Lichtenberg figure. This phenomenon occurs when a high-voltage electrical discharge passes through an insulating material, such as wood or acrylic, leaving behind branching patterns resembling lightning bolts.
The process involves the creation of a temporary electric field within the material, which polarizes its molecules. As the discharge propagates through the material, it causes localized breakdowns, creating branching paths along the way. These branching patterns are the characteristic Lichtenberg figures.
In the carnival trick, a high-voltage generator is used to create an electrical discharge on a piece of insulating material, such as acrylic. When a person touches the material or a conductive object placed on it, the discharge follows the path of least resistance, leaving behind the branching patterns. This effect is often used for entertainment purposes due to its visually striking appearance, resembling miniature lightning bolts frozen in the material. However, it’s crucial to handle such demonstrations with caution due to the potential hazards associated with high-voltage electricity.
