Critical Operations Power Systems

The original University of Michigan codes and standards enterprise advocated actively in Article 708 Critical Operations Power Systems (COPS) of the National Electrical Code (NEC) because of the elevated likelihood that the education facility industry managed assets that were likely candidates for designation critical operations areas by emergency management authorities.

Because the NEC is incorporated by reference into most state and local electrical safety laws, it saw the possibility that some colleges and universities — particularly large research universities with independent power plants, telecommunications systems and large hospitals  — would be on the receiving end of an unfunded mandate.   Many education facilities are identified by the Federal Emergency Management Association as community storm shelters, for example.

As managers of publicly owned assets, University of Michigan Plant Operations had no objection to rising to the challenge of using publicly owned education facilities for emergency preparedness and disaster recovery operations; only that meeting the power system reliability requirements to the emergency management command centers would likely cost more than anyone imagined — especially at the University Hospital and the Public Safety Department facilities.  Budgets would have to be prepared to make critical operations power systems (COPS) resistant to fire and flood damages; for example.

Collaboration with the Institute of Electrical and Electronic Engineers Industrial Applications Society began shortly after the release of the 2007 NEC.  Engineering studies were undertaken, papers were published (see links below) and the inspiration for the IEEE Education & Healthcare Facilities Committee developed to provide a gathering place for power, telecommunication and energy professionals to discover and promulgate leading practice.   That committee is now formally a part of IEEE and collaborates with IAS/PES JTCC assigned the task of harmonizing NFPA and IEEE electrical safety and sustainability consensus documents (codes, standards, guidelines and recommended practices.

The transcript of NEC Code Making Panel 13 — the committee that revises COPS Article 708 every three years — is linked below:

NEC CMP-13 First Draft Balloting

NEC CMP-13 Second Draft Balloting

The 2023 Edition of the National Electrical Code does not contain revisions that affect #TotalCostofOwnership — only refinement of wiring installation practices when COPS are built integral to an existing building that will likely raise cost.  There are several dissenting comments to this effect and they all dissent because of cost.   Familiar battles over overcurrent coordination persist.

Our papers and proposals regarding Article 708 track a concern for power system reliability — and the lack of power  — as an inherent safety hazard.   These proposals are routinely rejected by incumbent stakeholders on NEC technical panels who do not agree that lack of power is a safety hazard.  Even if lack of power is not a safety hazard, reliability requirements do not belong in an electrical wiring installation code developed largely by electricians and fire safety inspectors.  The IEEE Education & Healthcare Facilities Committee (IEEE E&H) maintains a database on campus power outages; similar to the database used by the IEEE 1366 committees that develop reliability indices to enlighten public utility reliability regulations.

Public input on the 2026 revision to the NEC will be received until September 7th.  We have reserved a workspace for our priorities in the link below:

The first elevator in the United States was installed at Harvard University in 1874. It was not a passenger elevator as we typically think of today, but rather a freight elevator used to move heavy items within a building. The installation of this elevator marked an important development in building technology and transportation within multi-story structures. It was based on the design of Elisha Otis, who is famous for inventing the safety elevator with a safety brake system that prevents the elevator from falling if the hoisting cable fails. Otis’ innovation played a pivotal role in making elevators safe and practical for everyday use, leading to their widespread adoption in buildings around the world.

Elevator design by the German engineer Konrad Kyeser (1405)

Education communities are stewards of 100’s of lifts, elevators and moving walks.  At the University of Michigan, there are the better part of 1000 of them; with 19 of them in Michigan Stadium alone.   The cost of building them — on the order of $50,000 to $150,000 per floor depending upon architectural styling — and the highly trained staff needed to operate, maintain and program interoperability software is another cost that requires attention.   All building design and construction disciplines — architectural, mechanical and electrical have a hand in making this technology safe and sustainabile.

We start with international and nationally developed best practice literature and work our way to state level adaptations.  Labor for this technology is heavily regulated.

Its a rarefied and crazy domain for the user-interest.  Expertise is passionate about safety and idiosyncratic but needs to be given the life safety hazard.  Today we review o pull together public consultation notices on relevant codes, standards and regulations today  11 AM/EDT.

The first recorded public use of an elevator was in 1743, in a private residence in France. It was created by a French scientist and inventor named Louis-François Dauprat. However, this early elevator was not used for public transportation or in a commercial building.

The first practical passenger elevator was invented by Elisha Graves Otis, an American industrialist and inventor, in 1852.  The Otis elevator used a safety device known as a “safety brake” or “safety hoist,” which prevented the elevator from falling in case the hoisting cable broke at a five-story building in New York City in 1857, known as Haughwout Building.

This invention revolutionized vertical transportation, allowing for the construction of taller buildings and changing the way people live and work in urban areas.

“Elevator Man”

The earliest installation of a passenger elevator in a university building in the United States was at the Massachusetts Institute of Technology.  In 1861, Otis Brothers & Co., the company founded by Elisha Graves Otis, installed the first passenger elevator on a university campus in the Rogers Building at MIT. The Rogers Building was a three-story structure that housed laboratories, classrooms, and offices for faculty and students. The installation of the passenger elevator provided vertical transportation within the building, making it more convenient for people to move between floors.

This early installation marked an important milestone in the history of vertical transportation on college and university campuses, and it paved the way for the adoption of elevators in other educational institutions as they expanded in size and height over time.

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:

C&S Connect: ASME Proposals Available for Public Review

Public consultation on revisions to the Elevator Safety Code closes April 15th. 

Safety Code for Existing Elevators and Escalators

Guide for Inspection of Elevators, Escalators, and Moving Walks

Guide for Elevator Seismic Design

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.

Today at 16:00 UTC we examine relatively recent transactions in electrotechnologies — power, information and communication technology — that are present (and usually required) in patient care settings.   At a patient’s bedside in a hospital or healthcare setting, various electrical loads or devices may be present to provide medical care, monitoring, and comfort. Some of the common electrical loads found at a patient’s bedside include:

Hospital Bed: Electric hospital beds allow for adjustments in height, head position, and leg position to provide patient comfort and facilitate medical procedures.

Patient Monitor: These monitors display vital signs such as heart rate, blood pressure, oxygen saturation, and respiratory rate, helping healthcare professionals keep track of the patient’s condition.

Infusion Pumps: These devices administer medications, fluids, and nutrients intravenously at a controlled rate.

Ventilators: Mechanical ventilators provide respiratory support to patients who have difficulty breathing on their own.

Pulse Oximeter: This non-invasive device measures the oxygen saturation level in the patient’s blood.

Electrocardiogram (ECG/EKG) Machine: It records the electrical activity of the heart and is used to diagnose cardiac conditions.

Enteral Feeding Pump: Used to deliver liquid nutrition to patients who cannot take food by mouth.

Suction Machine: It assists in removing secretions from the patient’s airway.

IV Poles: To hold and support intravenous fluid bags and tubing.

Warming Devices: Devices like warming blankets or warm air blowers are used to maintain the patient’s body temperature during surgery or recovery.

Patient Call Button: A simple push-button that allows patients to call for assistance from the nursing staff.

Overbed Tables: A movable table that allows patients to eat, read, or use personal items comfortably.

Reading Lights: Bedside lights that allow patients to read or perform tasks without disturbing others.

Television and Entertainment Devices: To provide entertainment and alleviate boredom during the patient’s stay.

Charging Outlets: Electrical outlets to charge personal electronic devices like smartphones, tablets, and laptops.

It’s important to note that the specific devices and equipment present at a patient’s bedside may vary depending on the level of care required and the hospital’s equipment standards. Additionally, strict safety measures and electrical grounding are essential to ensure patient safety when using electrical devices in a healthcare setting.  

We have been tracking the back-and-forth on proposals, considerations, adoption and rejections in the 3-year revision cycles of the 2023 National Electrical Code and the2021 Healthcare Facilities Code.  We will use the documents linked below as a starting point for discussion; and possible action:
