Elevator, escalator and moving walk systems are among the most complicated systems in any urban environment, no less so than on the #WiseCampus in which many large research universities have 100 to 1000 elevators to safely and economically operate, service and continuously commission. These systems are regulated heavily at state and local levels of government and have oversight from volunteers that are passionate about their work.
These “movement systems” are absorbed into the Internet of Things transformation. Lately we have tried to keep pace with the expansion of requirements to include software integration professionals to coordinate the interoperability of elevators, lifts and escalators with building automation systems for fire safety, indoor air quality and disaster management. Much of work requires understanding of the local adaptations of national building codes.
Some university elevator O&M units use a combination of in-house, manufacturer and standing order contractors to accomplish their safety and sustainability objectives.
In the United States the American Society of Mechanical Engineers is the dominant standards developer of elevator and escalator system best practice titles; its breakdown of technical committees listed in the link below:
As always, we encourage facility managers, elevator shop personnel to participate directly in the ASME Codes & Standards development process. For example, it would be relatively easy for our colleagues in the Phoenix, Arizona region to attend one or more of the technical committee meetings; ideally with operating data and a solid proposal for improving the A17 suite.
All ASME standards are on the agenda of our Mechanical, Pathway and Elevator & Lift colloquia. See our CALENDAR for the next online teleconferences; open to everyone. Use the login credentials at the upper right of our home page.

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.
Choosing between 3-pole and 4-pole transfer switches (Consulting-Specifying Engineer)
UL 1008 Standard for Safety for Transfer Switch Equipment is principally a product standard and has no direct competitor standard that matches its scope and adoption. Other standards or certifications may overlap in specific contexts:
IEC 60947-6-1 is used globally. It covers similar functionality but differs in testing and application, often requiring adaptation for North American compliance.
CSA C22.2 No. 178 is aligned with UL 1008 but specific to Canadian requirements. It is complementary rather than a competitor, as many products seek dual certification.
UL 1008 dominates in the U.S. due to its alignment with the NFPA 70 and NFPA 110; universally applied by commissioning and certificate of occupancy entities. For high-voltage switches, UL 1008A serves a niche role.
UL 1008 Transfer Switch Equipment 2022 is the latest revision. Note the $798 – $1,990 price for a legal copy. The price reflects the following:
UL 1008 is developed and updated by a Standards Technical Panel (STP) involving experts from industry, government, and academia. The process includes rigorous testing, research, and consensus-building, which incur significant expenses. Regular revisions, like the 9th edition in 2022, require ongoing investment to ensure compliance with evolving safety and regulatory requirements.
UL 1008 targets a niche market of engineers, manufacturers, and inspectors in the electrical power industry. Unlike consumer products, the limited demand for technical standards means costs are spread across fewer buyers, driving up the price per copy.
Certification to UL 1008 ensures safety and compliance with codes like NFPA 70, reducing liability risks for manufacturers and users. The high cost reflects the standard’s critical role in ensuring reliable, safe transfer switch equipment for applications like emergency power systems.
UL Standards & Engagement operates as a nonprofit, but it recovers costs through sales and licensing. Unlike open-access standards, UL’s proprietary model prioritizes quality and controlled distribution.
Single-copy purchases are priced high to encourage subscriptions or enterprise licenses, which offer broader access to multiple standards at a lower per-standard cost.
Throughout the Standards Michigan platform, we place product standards well below our coverage of interoperability standards that support our Safer-Simpler-Lower Cost- Longer Lasting priority. (See ABOUT).
Today is an impactful day for Schneider Electric in the U.S. as we break ground on our Columbia, Missouri Facility. Michael Quinn, SVP Power Products U.S. and ASCO, Schneider Electric, is kicking off the ribbon cutting ceremony alongside Missouri Governor, Mike Kehoe.
Disagree with someone and cannot persuade them? Do you need to hide your intransigence or ulterior motive? Then change the basis of discussion by changing the subject with a different definition.
This happens routinely in political discourse and rather frequently in best practice discovery and promulgation in building construction and settlement infrastructure standards[1]. Assuming all parties are negotiating in good faith resolution may lie in agreement on a common understanding of what a satisfying agreement might look like.
Admittedly, a subtle and challenging topic outside our wheelhouse[2] hence the need to improve our organization of this topic starting with today’s colloquium; with follow on sessions every month.
Starting 2025 we will organize our approach to this topic, thus:
Language 100. Survey of linguistic basics for developing codes, standards and regulations. Many vertical incumbents have developed their own style manuals
Language 200. Electrotechnical vocabulary
Language 300. Architectural and Allied trade vocabulary
Language 400. The language of government regulations; the euphemisms of politicians with influence over the built environment
Language 500. Advanced topics such as large language models or spoken dialects such as “High Michigan” — arguably, the standard American dialect where it applies to the standards listed above.
It may not be obvious how profound the choice of words and phrases have on leading practice discovery and promulgation. For example, “What is Gender” determines the number, placement and functionality of sanitary technologies in housing, hospitals and sporting. The United States has a Supreme Court justice that cannot define “woman”
As always, we will respond to public consultation opportunities wherever we can find them. Some organizations are better than this than others.
Today we limit our discussion to language changes in the catalogs of ANSI-accredited standards developers whose titles have the most influence over the interoperability of safety and sustainability technologies that create and sustain the built environment of educational settlements.
Every building construction discipline has its own parlance and terms of art.
This is enough for a one-hour session and, depending upon interest, we will schedule a breakout session outside of our normal “daily” office hours. Use the login credentials at the upper right of our home page.

Asset management applies to any organization. As such, understanding its terminology, principles, and outcomes is key to an organization’s success. ISO 55000:2024 provides an overview of #AssetManagement and its expected benefits. @isostandardshttps://t.co/XZsWvJJ8r4
(1) The United States government defines a “Green Building” as a building that has been designed, constructed, and operated in a way that reduces or eliminates negative impacts on the environment and occupants. The government has established various standards and certifications that buildings can achieve to be considered “green.”
The most widely recognized green building certification in the United States is the Leadership in Energy and Environmental Design (LEED) certification, which is administered by the U.S. Green Building Council (USGBC). To achieve LEED certification, a building must meet certain standards related to sustainable site development, water efficiency, energy efficiency, materials selection, and indoor environmental quality.
In addition to the LEED certification, there are other programs and standards that can be used to measure and certify the sustainability of buildings, such as the Green Globes rating system and the Living Building Challenge.
Overall, the goal of green building is to create buildings that are not only environmentally sustainable but also healthier, more comfortable, and more efficient for occupants, while reducing energy consumption and greenhouse gas emissions. By promoting green building practices, the U.S. government aims to reduce the environmental impact of the built environment and move towards a more sustainable future.

Overall, the simplicity, readability, versatility, and large community support of Python make it a valuable programming language to learn for anyone interested in software development including building automation.
As open source software, anyone may suggest an improvement to Python(3.X) starting at the link below:
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.
