ISO Technical Committees | ANSI (U.S. Participation in ISO Activities)

Many large research universities have significant medical research and healthcare delivery enterprises. The leadership of those enterprises discount the effect of standards like this at their peril. It is easy to visualize that this document will have as transformative effect upon the healthcare industry as the ISO 9000 series of management standards in the globalization of manufacturing.

Scope

Standardization in the field of healthcare organization management comprising, terminology, nomenclature, recommendations and requirements for healthcare-specific management practices and metrics (e.g. patient-centered staffing, quality, facility-level infection control, pandemic management, hand hygiene) that comprise the non-clinical operations in healthcare entities.

Excluded are horizontal organizational standards within the scope of:

    • quality management and quality assurance (TC 176);
    • human resource management (TC 260);
    • risk management (TC 262);
    • facility management (TC 267), and;
    • occupational health and safety management (TC 283).

Also excluded are standards relating to clinical equipment and practices, enclosing those within the scope of TC 198 Sterilization of health care products.

This committee is led by the US Technical Advisory Group Administrator —Ingenesis.   The committee is very active at the moment, with new titles drafted, reviewed and published on a near-monthly basis,

Today we feature the catalog of the Illumination Engineering Society — one of the first names in standards-setting in illumination technology, globally* with particular interest in its leading title IES LP-1 | LIGHT + DESIGN Lighting Practice: Designing Quality Lighting for People and Buildings.

From its prospectus:

“…LIGHT + DESIGN was developed to introduce architects, lighting designers, design engineers, interior designers, and other lighting professionals to the principles of quality lighting design. These principles; related to visual performance, energy, and economics; and aesthetics; can be applied to a wide range of interior and exterior spaces to aid designers in providing high-quality lighting to their projects.

Stakeholders: Architects, interior designers, lighting practitioners, building owners/operators, engineers, the general public, luminaire manufacturers.  This standard focuses on design principles and defines key technical terms and includes technical background to aid understanding for the designer as well as the client about the quality of the lighted environment. Quality lighting enhances our ability to see and interpret the world around us, supporting our sense of well-being, and improving our capability to communicate with each other….”


The entire catalog is linked below:

Illumination technologies run about 30 percent of the energy load in a building and require significant human resources at the workpoint — facility managers, shop foremen, front-line operations and maintenance personnel, design engineers and sustainability specialists.  The IES has one of the easier platforms for user-interest participation:

IES Standards Open for Public Review

Because the number of electrotechnology standards run in the thousands and are in continual motion* we need an estimate of user-interest in any title before we formally request a redline because the cost of obtaining one in time to make meaningful contributions will run into hundreds of US dollars; apart from the cost of obtaining a current copy.

We maintain the IES catalog on the standing agendas of our Electrical, Illumination and Energy colloquia.   Additionally, we collaborate with experts active in the IEEE Education & Healthcare Facilities Committee which meets online 4 times monthly in European and American time zones; all colloquia online and open to everyone.   Use the login credentials at the upper right of our home page to join us.

Data Center Operations & Maintenance

"One day ladies will take their computers for walks in the park and tell each other, "My little computer said such a funny thing this morning" - Alan Turing

Information and communications technology (ICT) is a fast-moving economic space in which a mix of consensus, consortia and open-source standards form the broad contours of leading practice.   ICT standards tend to follow international developments — more so than, say, fire safety standards which are more familiar to education facility leadership.  All school districts, colleges, universities and university-affiliated health care systems have significant product, system, firmware and labor resources allocated toward ICT.

The Building Industry Consulting Service International (BICSI) is a professional association supporting the advancement of the ICT community in all markets.   This community is roughly divided between experts who deal with “outside-plant” systems and “building premise” systems on either side of the ICT demarcation (or Point-of-Presence).   BICSI standards cover the wired and wireless spectrum of voice, data, electronic safety & security, project management and audio & video technologies.  Its work is divided among several committees as shown in the landing page of its standards setting enterprise, linked below:

BICSI International Standards Program

The stars on the map above indicate where BICSI Standards are currently in use (CLICK ON IMAGE).

Education communities are stewards of significant information and communication technology infrastructure.  Accordingly, we track the development of BICSI 009 Data Center Operations and Maintenance Best Practices.   This title provides requirements, recommendations, and best practices for the operation and maintenance of data centers including but not limited to standard operating procedures, emergency operating procedures, maintenance, governance, and management.  Those comments are now being integrated into a revised standard to be released as soon as the restrictions of the pandemic are eased.  For more information you may communicate directly with Jeff Silveira (jSilveira@bicsi.org)

As of this posting, all BICSI best practice titles are stable and current; though our recent communication with its leadership indicates that BICSI standards setting has been slowed by the pandemic.

A fair amount of content in BICSI standards are inspired by movement in safety concepts of the National Electrical Code; particularly on matters involving wiring, grounding and lightning protection.  We maintain all BICSI best practice titles on the standing agenda of our Infotech 200 teleconference.  See our CALENDAR for the next online meeting; open to the public.   On this topic we collaborate with the IEEE Education & Healthcare Facilities Committee meets four times monthly in European and American time zones; also open to the public.

Data Center Wiring

The bookwheel, also known as a revolving bookcase, was invented by an Italian scholar and polymath named Agostino Ramelli. Ramelli was born in 1531 in Ponte Tresa, a town in present-day Italy, and he lived during the Renaissance period.

Ramelli’s invention, described in his work titled “Le diverse et artificiose machine del capitano Agostino Ramelli” (The Various and Ingenious Machines of Captain Agostino Ramelli), was published in 1588. This book showcased a collection of 195 mechanical devices.  

Ramelli’s work contributed to the growing interest in mechanical inventions during the Renaissance period. His bookwheel design remains a fascinating example of early engineering and ingenuity, highlighting the desire for knowledge and practical solutions in the pursuit of learning and scholarly endeavors.

The standard of care for wiring safety for data centers —  a continually expanding presence in education communities even before the pandemic  — is established in National Electrical Code Articles 645 (Information Technology Equipment), Article 646 (Modular Data Centers) and Article 647 (Sensitive Electronic Equipment).   You will notice that these articles cover the topic comprehensively and bear the imprint of competing Producer-Interest groups.  There are no User-Interest representatives on Code-Making Panel 12 that represent the final fiduciary in education communities even though education communities are one of the largest markets for information and communication technology systems.

We will use these in our exploration of what we might propose for improvements in the 2026 revision.  Public comment on the First Draft of the 2026 Edition will be received until August 28th.

The issues that have been in play in these articles of the NEC are familiar to veterans of the “food fight” – occupancy classification, cable specifications, fire protection, ventilation, energy consumption, surge protection, licensing of engineers. etc.  We look for market-making excesses by opposing stakeholders that seek to limit their risk while raising the (financial) risk to education communities.

We encourage our colleagues to participate in the NFPA code development process directly.  We also encourage stakeholders in education communities — students, faculty and staff  to join us during any of the teleconferences we co-host with the IEEE Education & Healthcare Facilities Committee 4 times monthly in both European and American time zones.   See our CALENDAR for the next online meeting.

Canadian Parliament Debate on Standards Incorporated by Reference

“The Jack Pine” | Tom Thomson (1916) | National Gallery of Canada

 

Originally posted January 2014

In these clips — selected from Canadian Parliamentary debate in 2013 — we observe three points of view about Incorporation by reference (IBR); a legislative drafting technique that is the act of including a second document within a main document by referencing the second document.

This technique makes an entire second (or referenced) document a part of the main document.  The consensus documents in which we advocate #TotalCostofOwnership concepts are incorporated by reference into legislation dealing with safety and sustainability at all levels of government.  This practice — which many consider a public-private partnership — is a more effective way of driving best practices for technology, and the management of technology, into regulated industries.

Parent legislation — such as the Higher Education Act of 1965, the Clean Air Act and the Energy Policy Act – almost always require intermediary bureaucracies to administer the specifics required to accomplish the broad goals of the legislation.  With the gathering pace of governments everywhere expanding their influence over larger parts of the technologies at the foundation of national economies; business and technology standards are needed to secure that influence.  These standards require competency in the application of political, technical and financial concepts; competencies that can only be afforded by incumbent interests who build the cost of their advocacy into the price of the product or service they sell to our industry.  Arguably, the expansion of government is a reflection of the success of incumbents in business and technical standards; particularly in the compliance and conformity industries.

About two years ago, the US debate on incorporation by reference has been taken to a new level with the recent statement released by the American Bar Association (ABA):

16-164-Incorporation-by-Reference-ABA-Resolution-and-Report

The American National Standards Institute responded to the ABA with a statement of its own.

16-164-ANSI-Response-to-ABA-IBR-06-16 (1)

The incorporation by reference policy dilemma has profound implications for how we safely and economically design, operate and maintain our “cities-within-cities” in a sustainable manner but, admittedly, the results are only visible in hindsight over a time horizon that often exceed the tenure of a typical college or university president.

A recent development — supporting the claims of ANSI and its accredited standards developers — is noteworthy:

The National Institute for Standards and Technology (NIST) manages a website — Standards.GOV — that is a single access point for consensus standards incorporated by reference into the Code of Federal Regulations: Standards Incorporated by Reference Database.   Note that this database does not include specific reference to safety and sustainability codes which are developed by standards setting organizations (such as NFPA, ICC, IEEE, ASHRAE and others) and usually incorporated by reference into individual state public safety and technology legislation.

Management of Assets in Power Systems

“Mount Fuji from Lake Yamanaka” Takahashi Shōtei (1871-1945) | Los Angeles County Museum of Art

The Japanese Standards Association is the Global Secretariat for a standardization project devoted to the discovery and promulgation of common methods and guidelines for coordinated lifetime management of network assets in power systems to support good asset management.  In addition, this may include the development of new methods and guidelines required to keep pace with development of electrotechnologies excluding generation assets; covered by other IEC standards.

There has, and will continue to be significant investment in electricity assets which will require ongoing management to realise value for the organizations. In the last 5 years, there has been USD 718 billion investment for electricity, spending on electricity networks and storage continued, reaching an all-time high of USD 277 billion in 2016. In the United States (17% of the total) and Europe (13%), a growing share is going to the replacement of ageing transmission and distribution assets.  A more fully dimensioned backgrounder on the business environment that drives the market for this title is available in the link below:

IEC/TC 123 Strategic Business Plan

Begun in 2018, this is a relatively new project with three stabilized titles:

IEC 60050-693 ED1: Management of network assets in power systems – Terminology

IEC 63223-2 ED1: Management of network assets in power systems – Requirements

IEC TS 63224 ED1: Management of network assets in power systems – Practices and case studies

Electropedia: The World’s Online Electrotechnical Vocabulary

It is early in this project’s lifecycle; far too early to find it referenced in public safety and energy laws in the United States where it would affect #TotalCostofOwnership.   Where we should, we follow the lead of the USNC/IEC for the United States, while still mindful that many of our IEEE colleagues follow the lead of their own national standards body.

Because this project fills an obvious gap in good practice literature we maintain this project on our 4 times monthly electrotechnology colloquium that we co-host with the IEEE Education & Healthcare Facilities Committee.   See our CALENDAR for the next online meeting; open to everyone.

Comment on FERC Action

The Federal Energy Regulatory Commission is an independent agency within the U.S. federal government that regulates interstate transmission of electricity, natural gas, and oil. It oversees wholesale energy markets, pipeline infrastructure, and hydroelectric projects, ensuring fair rates and reliability. While independent, FERC operates under the Department of Energy’s umbrella but does not take direct orders from the executive branch.

FERC enforces energy laws, approves infrastructure projects, and regulates market competition. FERC plays a crucial role in balancing economic, environmental, and energy security concerns, aiming to maintain a stable and efficient energy system across the United States.  Since the U.S. shares interconnected electricity grids with Canada and Mexico, FERC’s decisions on transmission rules and pricing affect energy flows and grid reliability in both countries.

Our interest lies in closing a technical gap that exists upstream from the building service point and downstream from the utility supply point. Some, not all of it, can be accomplished with titles in the IEEE catalog.

Given the dominance of vertical incumbents in the electric power domain, we have submitted a tranche of reliability concepts into the ASHRAE, NFPA and ICC catalogs — not so much with the expectation that they will be gratefully received — but that our proposals will unleash competitive energies among developers of voluntary consensus standards.

One of our proposals was heard at the April-May and October meetings of the International Code Council.  We are happy to discuss the outcome of that proposal any day at the usual hour.

Transmission Planning Using a Reliability Criterion

Readings / The Administrative State

In power system engineering, availability and reliability are two important concepts, but they refer to different aspects of the system’s performance.

Reliability:

  • Reliability refers to the ability of a power system to perform its intended function without failure for a specified period under given operating conditions. It is essentially a measure of how dependable the system is.
  • Reliability metrics often include indices such as the frequency and duration of outages, failure rates, mean time between failures (MTBF), and similar measures.
  • Reliability analysis focuses on identifying potential failure modes, predicting failure probabilities, and implementing measures to mitigate risks and improve system resilience.Availability:
  • Availability, on the other hand, refers to the proportion of time that a power system is operational and able to deliver power when needed, considering both scheduled and unscheduled downtime.
  • Availability is influenced by factors such as maintenance schedules, repair times, and system design redundancies.
  • Availability is typically expressed as a percentage and can be calculated using the ratio of the uptime to the total time (uptime plus downtime).
  • Availability analysis aims to maximize the operational readiness of the system by minimizing downtime and optimizing maintenance strategies.

Reliability focuses on the likelihood of failure and the ability of the system to sustain operations over time, while availability concerns the actual uptime and downtime of the system, reflecting its readiness to deliver power when required. Both concepts are crucial for assessing and improving the performance of power systems, but they address different aspects of system behavior.

 UPDATED POLICIES ON U.S. DECARBONIZATION AND TECHNOLOGY TRANSITIONS


June 15:FERC Finalizes Plans to Boost Grid Reliability in Extreme Weather Conditions

On Monday June 13th, Federal Energy Regulatory Commission commissioners informed the House Committee on Energy and Commerce that the “environmental justice” agenda prohibits reliable dispatchable electric power needed for national power security. One megawatt of natural gas generation does not equal one megawatt of renewable generation. The minority party on the committee — the oldest standing legislative committee in the House of Representatives (established 1795) — appears indifferent to the reliability consequences of its policy.

Joint Federal-State Task Force on Electric Transmission

“Our nation’s continued energy transition requires the efficient development of new transmission infrastructure. Federal and state regulators must address numerous transmission-related issues, including how to plan and pay for new transmission infrastructure and how to navigate shared federal-state regulatory authority and processes. As a result, the time is ripe for greater federal-state coordination and cooperation.”

Interconnected Electric Power Production Sources “Microgrids”

“Landscape with a Farm House and Windmill” (1680) / Jacob Isaaksz van Ruisdael

We have always taken a forward-looking approach to the National Electrical Code (NEC) because there is sufficient supply of NEC instructors and inspectors and not enough subject matter experts driving user-interest ideas into it.  Today we approach the parts of the 2023 NEC that cover wiring safety for microgrid systems; a relatively new term of art that appropriates safety and sustainability concepts that have existed in electrotechnology energy systems for decades.

Turn to Part II of Article 705 Interconnected Electric Power Production Sources:

Free Access 2023 National Electrical Code

You will notice that microgrid wiring safety is a relatively small part of the much larger Article 705 Content.   There were relatively minor changes to the 2017 NEC in Section 705.50  — but a great deal of new content regarding Microgrid Interconnection Devices, load side connections, backfeeding practice and disconnecting means — as can be seen in the transcripts of Code-Making Panel 4 action last cycle:

Code‐Making Panel 4 Public Input Report (692 Pages)

Code-Making Panel 4 Public Comment Report (352 Pages)

Keep in mind that the NEC says nothing (or nearly very little, in its purpose stated in Section 90.2) about microgrid economics or the life cycle cost of any other electrical installation.  It is the claim about economic advantages of microgrids that drive education facility asset management and energy conservation units to conceive, finance, install, operate and — most of all — tell the world about them.

In previous posts we have done our level best to reduce the expectations of business and finance leaders of dramatic net energy savings with microgrids — especially on campuses with district energy systems.  Microgrids do, however, provide a power security advantage during major regional contingencies — but that advantage involves a different set of numbers.

Note also that there is no user-interest from the education facility industry — the largest non-residential building construction market in the the United States — on Panel 4.   This is not the fault of the NFPA, as we explain in our ABOUT.

The 2023 NEC was released late last year.

 

The 2026 revision cycle is in full swing with public comment on the First Draft receivable until August 24, 2024.  Let’s start formulating our ideas using the 2023 CMP-4 transcripts.   The link below contains a record of work on the 2023 NEC:

Underground Electrotechnology

Best practice literature to be covered in our 11 AM session today are listed below.  These codes and standards ensure safety, reliability, and compliance for underground electrical and telecommunications installations:

2028 National Electrical Safety Code

  • National Electrical Code (NEC), NFPA 70
    • Relevance: The NEC, published by the National Fire Protection Association, is the primary standard for safe electrical installations in the U.S. Articles 300 (Wiring Methods), 310 (Conductors for General Wiring), and 230 (Services) cover underground wiring, including burial depths, conduit requirements, and direct-burial cables like Type UF and USE-2. For example, NEC 300.5 specifies minimum cover depths (e.g., 24 inches for direct-burial cables, 18 inches for PVC conduit).
    • Key Aspects: Rules for conductor protection, grounding, GFCI requirements, and conduit types (e.g., Schedule 80 PVC). Adopted by most U.S. jurisdictions with local amendments.

ANSI/TIA-568 Series (Commercial Building Telecommunications Cabling Standards)

  • Relevance: Governs low-voltage telecommunications cabling, including underground installations. TIA-568.2-D (Balanced Twisted-Pair) and TIA-568.3-D (Optical Fiber) specify performance requirements for cables like Cat6 and fiber optics, including maximum distances (e.g., 100 meters for twisted-pair).
  • Key Aspects: Ensures signal integrity, proper separation from high-voltage lines, and compliance for plenum or direct-burial-rated cables. Voluntary unless mandated by local codes.

IEEE 835 (Standard Power Cable Ampacity Tables)

  • Relevance: Provides ampacity ratings for underground power cables, critical for sizing conductors to prevent overheating.
  • Key Aspects: Includes data for direct-burial and ducted installations, considering soil thermal resistivity and ambient conditions. Often referenced alongside NEC for high-current applications.

UL 83 (Standard for Thermoplastic-Insulated Wires and Cables)

  • Relevance: Underwriters Laboratories standard for wires like THWN-2, commonly used in underground conduits. Ensures cables meet safety and performance criteria for wet locations.
  • Key Aspects: Specifies insulation durability, temperature ratings, and suitability for direct burial or conduit use. NEC requires UL-listed cables for compliance.

OSHA 1910.305 (Wiring Methods, Components, and Equipment)

  • Relevance: U.S. Occupational Safety and Health Administration standard for workplace electrical safety, including underground installations in industrial settings.
  • Key Aspects: Specifies approved wiring methods (e.g., armored cable, conduit) and enclosure requirements for underground cable trays or boxes. Focuses on worker safety during installation and maintenance.

CSA C22.1 (Canadian Electrical Code)

  • Relevance: Canada’s equivalent to the NEC, governing underground electrical installations. Similar to NEC but tailored to Canadian conditions and regulations.
  • Key Aspects: Defines burial depths, conduit types, and grounding requirements. For example, low-voltage cables (<30V) require 6-inch burial depth, like NEC.

Notes:

  • Regional Variations: Always consult local building authorities, as codes like the NEC or AS/NZS 3000 may have amendments. For example, some U.S. states reduce burial depths for GFCI-protected circuits (NEC 300.5).
  • Low-Voltage vs. High-Voltage: Standards like TIA-568 and ISO/IEC 11801 focus on low-voltage (e.g., <50V) telecommunications, while NEC and IEC 60364 cover both power and telecom.
  • Practical Compliance: Before installation, call 811 (U.S.) or equivalent to locate underground utilities, and obtain permits/inspections as required by local codes.
  • Critical Examination: While these standards are authoritative, they can lag behind technological advancements (e.g., new cable types like GameChanger exceeding TIA-568 limits). Over-reliance on minimum requirements may limit performance for cutting-edge applications.
