Our tenure in the 2026 National Electrical Code will result in at least a 10 percent reduction in the cost of building premise wiring — (mostly in the feeder power chain) — in healthcare facilities; based on the results of last month’s meeting of Code Making Panel 15.
Assuming electrical power infrastructure is 15 percent of in a $920 million facility like this (excluding interior moveable fixtures), that would have meant an approximate $14 million reduction in cost. That cost savings cannot be realized because it was designed to an earlier version of the National Electrical Code.
Note the following proposed changes in the transcript above: E59-24, F62-24, Section 323
Modular classrooms, often used as temporary or semi-permanent solutions for additional educational space, have specific requirements in various aspects to ensure they are safe, functional, and comfortable for occupants. Today we will examine best practice literature for structural, architectural, fire safety, electrical, HVAC, and lighting requirements. Use the login credentials at the upper right of our home page.
Structural Requirements
Foundation and Stability: Modular classrooms require a stable and level foundation. This can be achieved using piers, slabs, or crawl spaces. The foundation must support the building’s weight and withstand environmental forces like wind and seismic activity.
Frame and Load-Bearing Capacity: The frame, usually made of steel or wood, must support the load of the classroom, including the roof, walls, and occupants. Structural integrity must comply with local building codes.
Durability: Materials used should be durable and capable of withstanding frequent relocations if necessary.
Architectural Requirements
Design and Layout: Modular classrooms should be designed to maximize space efficiency while meeting educational needs. This includes appropriate classroom sizes, storage areas, and accessibility features.
Accessibility: Must comply with the Americans with Disabilities Act (ADA) or other relevant regulations, ensuring accessibility for all students and staff, including ramps, wide doorways, and accessible restrooms.
Insulation and Soundproofing: Adequate insulation for thermal comfort and soundproofing to minimize noise disruption is essential.
Fire Safety Requirements

By adhering to these requirements, modular classrooms can provide safe, functional, and comfortable educational spaces that meet the needs of students and staff while complying with local regulations and standards.
Brigham Young University Idaho is a private university located in Rexburg, Idaho, United States. It is owned and operated by The Church of Jesus Christ of Latter-day Saints and is a part of the Church Educational System which recognizes moral absolutes at the foundation of a federal democratic republic that makes their university possible. It offers a variety of undergraduate degrees in fields such as business, education, health, and the humanities. The university also offers online courses and programs for distance learners.
One unique aspect of BYU-Idaho is its emphasis on the integration of faith and learning. All students, regardless of their religious background, are required to take religion courses as part of their degree program. The university also has a code of conduct that includes standards for dress, grooming, behavior, and academic honesty.
Abstract: We address the problem of predicting whether a driver facing the yellow-light-dilemma will cross the intersection with the red light. Based on driving simulator data, we propose a stochastic hybrid system model for driver behavior. Using this model combined with Gaussian process estimation and Monte Carlo simulations, we obtain an upper bound for the probability of crossing with the red light. This upper bound has a prescribed confidence level and can be calculated quickly on-line in a recursive fashion as more data become available. Calculating also a lower bound we can show that the upper bound is on average less than 3% higher than the true probability. Moreover, tests on driving simulator data show that 99% of the actual red light violations, are predicted to cross on red with probability greater than 0.95 while less than 5% of the compliant trajectories are predicted to have an equally high probability of crossing. Determining the probability of crossing with the red light will be important for the development of warning systems that prevent red light violations.
The heating and cooling requirements of K-12 schools, college and university educational, medical research and healthcare delivery campuses are a large market for boiler pressure vessel manufacturers, installers, maintenance personnel and inspectors. The demand for building new, and upgrading existing boilers — either single building boilers, regional boilers or central district energy boilers — presents a large market for professional engineering firms also. A large research university, for example, will have dozens, if not well over 100 boilers that heat and cool square footage in all climates throughout the year. The same boilers provide heating and cooling for data centers, laundry operations, kitchen steam tables in hospitals and dormitories.
“…The International Boiler and Pressure Vessel Code establishes rules of safety — relating only to pressure integrity — governing the design, fabrication, and inspection of boilers and pressure vessels, and nuclear power plant components during construction. The objective of the rules is to provide a margin for deterioration in service. Advancements in design and material and the evidence of experience are constantly being added…”
Many state and local governments incorporate the BPVC by reference into public safety regulations and have established boiler safety agencies. Boiler explosions are fairly common, as a simple internet search on the term “school boiler explosion” will reveal. We linked one such incident at the bottom of this page.

The 2023 Edition of the BPVC is the current edition; though the document is divided into many sections that change quickly.
Two characteristics of the ASME standards development process are noteworthy:
Only the proposed changes to the BPVC are published. The context surrounding a given change may be lost or not seen unless access to previous version is available. Knowledgeable experts who contribute to the development of the BPVC usually have a previous version, however. Newcomers to the process may not.
The BPVC has several breakout committees; owing to its longer history in the US standards system and the gathering pace of complexity in this technology.
We unpack the ASME bibliography primarily during our Mechanical, Plumbing and Energy colloquia; and also during our coverage of large central laundry and food preparation (Kitchens 100) colloquia. See our CALENDAR for the next online meeting, open to everyone.

The MIL-SPEC catalog and its evolution have had a significant impact on various industries beyond the military sector. Many civilian industries have adopted military standards as a benchmark for quality, reliability, and compatibility in their products and processes.
World War II Era:
The MIL-SPEC system traces its roots back to the World War II era when the U.S. military faced challenges in coordinating manufacturing efforts across multiple suppliers. To address these challenges, the military began developing specifications and standards that detailed the requirements for various equipment and materials, including dimensions, materials, performance criteria, and testing procedures.
Post-World War II:
After World War II, the MIL-SPEC catalog expanded significantly to cover a wide range of military equipment, ranging from electronics and aircraft components to clothing and food supplies. The standards were continuously updated and revised based on technological advancements, lessons learned, and evolving military needs.
Evolution into MIL-STD:
In the 1950s and 1960s, the MIL-SPEC system evolved into the Military Standard (MIL-STD) system to provide even more comprehensive and detailed specifications. MIL-STD documents incorporated a broader scope of requirements, including design criteria, quality control processes, and test methodologies. The MIL-STD system aimed to ensure consistent design and manufacturing practices across contractors and suppliers.
MIL-STD Transition to Commercial Standards:
Over time, the reliance on MIL-STDs started to decline, and there was a shift towards adopting commercial standards whenever possible. This transition allowed the military to benefit from the advancements and cost efficiencies of commercial technologies. However, certain critical military-specific standards, such as those related to security and specialized equipment, continued to be maintained within the MIL-STD framework.
DoD’s Transition to Performance-Based Specifications:
In recent years, the DoD has been moving away from prescriptive specifications (MIL-STDs) towards performance-based specifications. Performance-based specifications focus on defining the desired outcomes and performance requirements while allowing contractors greater flexibility in meeting those requirements. This approach encourages innovation, cost-effectiveness, and broader industry participation in military contracts.
