Healthcare Facilities Code

“The Doctor”  1891 Sir Luke Fildes

The NFPA 99 Healthcare Facilities Code committee develops a distinct consensus document (i.e. “regulatory product”) that is distinct from National Electrical Code Article 517; though there are overlaps and gaps that are the natural consequence of changing technology and regulations.  It is worthwhile reviewing the scope of each committee:

NFPA 99 Scope: This Committee shall have primary responsibility for documents that contain criteria for safeguarding patients and health care personnel in the delivery of health care services within health care facilities: a) from fire, explosion, electrical, and related hazards resulting either from the use of anesthetic agents, medical gas equipment, electrical apparatus, and high frequency electricity, or from internal or external incidents that disrupt normal patient care; b) from fire and explosion hazards; c) in connection with the use of hyperbaric and hypobaric facilities for medical purposes; d) through performance, maintenance and testing criteria for electrical systems, both normal and essential; and e) through performance, maintenance and testing, and installation criteria: (1) for vacuum systems for medical or surgical purposes, and (2) for medical gas systems; and f) through performance, maintenance and testing of plumbing, heating, cooling , and ventilating in health care facilities.

NFPA 70 Article 517 Scope:  The provisions of this article shall apply to electrical construction and installation criteria in healthcare facilities that provide services to human beings.  The requirements in Parts II and III not only apply to single-function buildings but are also intended to be individually applied to their respective forms of occupancy within a multi-function building (e.g. a doctor’s examining room located within a limited care facility would be required to meet the provisions of 517.10)   Informational Note: For information concerning performance, maintenance, and testing criteria, refer to the appropriate health care facilities documents.

In short, NFPA 70 Article 517 is intended to focus only on electrical safety issues though electrotechnology complexity and integration in healthcare settings (security, telecommunications, wireless medical devices, fire safety, environmental air control, etc.) usually results in conceptual overlap with other regulatory products such as NFPA 101 (Life Safety Code) and the International Building Code.

Several issues were recently debated by the Article 517 technical committee during the 2023 National Electrical Code Second Draft meetings

  • The conditions under which reconditioned electrical equipment be installed in healthcare settings; contingent on listing and re-certification specifics.
  • Relaxation of the design rules for feeder and branch circuit sizing through the application of demand factors.
  • Application of ground fault circuit interrupters.
  • “Rightsizing” feeder and branch circuit power chains (Demand factors in Section 517.22)
  • Patient care space categories
  • Independence of power sources (517.30)

There are, of course, many others, not the least of which involves emergency management.  For over 20 years our concern has been for the interdependency of water and electrical power supply to university hospitals given that many of them are part of district energy systems.

We need to “touch” this code at least once a month because of its interdependence on other consensus products by other standards developing organizations.  To do this we refer NFPA 99 standards action to the IEEE Education & Healthcare Facilities Committee which meets online four times monthly in European and American time zones.

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.

Mighty spirited debate.   Wireless charging from in-ground facilities employing magnetic resonance are noteworthy.

 

Technical committees meet November – January to respond.   In the intervening time it is helpful  break down the ideas that were in play last cycle.  The links below provide the access point:

Public Input Report Panel 12

Public Comment Report Panel 12

Panel 12 Final Ballot

We find a fair amount of administrative and harmonization action; fairly common in any revision cycle.   We have taken an interest in a few specific concepts that track in academic research construction industry literature:

  • Correlation with Underwriters Laboratory product standards
  • Bi-Directional Charging & Demand Response
  • Connection to interactive power sources

As a wiring safety installation code — with a large installer and inspection constituency — the NEC is usually the starting point for designing the power chain to electric vehicles.   There is close coupling between the NEC and product conformance organizations identified by NIST as Nationally Recognized Testing Laboratories; the subject of a separate post.

After the First Draft is released June 28th public comment is receivable until August 19th.

We typically do not duplicate the work of the 10’s of thousands of National Electrical Code instructors who will be fanning out across the nation to host training sessions for electrical professionals whose license requires mandatory continuing education.  That space has been a crowded space for decades.   Instead we co-host “transcript reading” sessions with the IEEE Education & Healthcare Facilities Committee to sort through specifics of the 2020 NEC and to develop some of the ideas that ran through 2020 proposals but did not make it to final ballot and which we are likely to see on the docket of the 2023 NEC revision.   That committee meets online 4 times monthly.  We also include Article 625 on the standing agenda of our Mobility colloquium; open to everyone.   See our CALENDAR for the next online meeting

Energy Standard for *Sites* and Buildings

Proposed Addendum ae to Standard 90.1-2022 (21 pages) | Comments due July 22*

ANSI Standards Action Weekly Edition

 

The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) is an ANSI-accredited continuous-maintenance standards developer (a major contributor to what we call a regulatory product development “stream”).   Continuous maintenance means that changes to its consensus products can change in as little as 30 days so it is wise to keep pace.

Among the leading titles in its catalog is ASHRAE 90.1 Energy Standard for Sites and Buildings Except Low-Rise Residential Buildings.  Standard 90.1 has been a benchmark for commercial building energy codes in the United States and a key basis for codes and standards around the world for more than 35 years.  Free access to ASHRAE 90.1 version is available at the link below:

READ ONLY Version of 2022 ASHRAE 90.1

Redlines are released at a fairly brisk pace — with 30 to 45 day consultation periods.  A related title — ASHRAE 189.1 Standard for the Design of High Performance Green Buildings — first published in 2009 and far more prescriptive in its scope heavily  references parent title 90.1 so we usually them as a pair because 189.1 makes a market for green building conformance enterprises. Note the “extreme prescriptiveness” (our term of art) in 189.1 which has the practical effect of legislating engineering judgement, in our view.

25 January 2023: Newly Released ASHRAE 90.1-2022 Includes Expanded Scope For Building Sites

ASHRAE committees post their redlines at the link below:

Online Standards Actions & Public Review Drafts

Comments on  changes relevant to cooling installations will be received until July 22nd. (Addendum ae)

Education industry facility managers, energy conservation workgroups, sustainability officers, electric shop foreman, electricians and front-line maintenance professionals who change lighting fixtures, maintain environmental air systems are encouraged to participate directly in the ASHRAE consensus standard development process.

We also maintain ASHRAE best practice titles as standing items on our Mechanical, Water, Energy and Illumination colloquia.  See our CALENDAR for the next online meeting; open to everyone.

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,

Interoperability of Distributed Energy Resources

IEEE Standard for Interconnecting Distributed Resources with Electric Power Systems is effectively the global standard for interconnection of distributed resources with large scale electric power systems.  It provides requirements relevant to the performance, operation, testing, safety, and maintenance of the interconnection.  Apart from the power reliability and sustainability zietgeist we have seen in campus bulk power distribution systems, this title is usually referenced in research projects undertaken in university research enterprises.  The standard is intended to be universally adoptable, technology-neutral, and cover distributed resources as large 10 MVA.  To wit:

IEEE 1547-2018 Standard for Interconnection and Interoperability of Distributed Energy Resources with Associated Electric Power Systems Interfaces: This standard — emerging from IEEE Root Project 1547.3 — 2007 asserts first principles for improved performance for distributed energy resources, connected to the grid. NIST funding aided this standard’s development.   Links to related titles, recently released for public consultation, are listed below:

We collaborate with the IEEE Education & Healthcare Facilities Committee on this an related titles.   This committee’s meetings are held 4 times monthly in European and American time zones.  International Electrical Technical Commission titles are items on the standing agenda; a few representative titles are listed in addition to IEEE titles below:

IEC 62746-10-1:2018 Systems Interface Between Customer Energy Management System and the Power Management System – Part 10-1: Open Automated Demand Response: This standard specifies how to implement a two-way signaling system, between utilities and customers, thus allowing utilities to adjust the grid’s load, based on demand. NIST’s David Holmberg and Steve Bushby presented research to the International Electrotechnical Commission (IEC), aiding this US standard’s acceptance as an international one.

IEC 62746-10-3:2018, Systems Interface Between Customer Energy Management System and the Power Management System – Part 10-3: Open Automated Demand Response – Adapting Smart Grid User Interfaces to the IEC Common Information Model: Related to the previous standard, IEC 62746-10-3:2018 defines the interfaces, as well as, the messaging for this two-way signaling system. NIST’s Holmberg and Bushby also facilitated this international standard’s acceptance.

IEEE 21451-001-2017 Recommended Practice for Signal Treatment Applied to Smart Transducers: This guide supports the ability to uniformly processing and classifying data from sensors and actuators in a smart system. The standard enables a common interpretation of data and grid interoperability. NIST personnel served on this standard’s working group, providing NIST research on sensors and actuators.

IEEE 2030.7-2017 Standard for the Specification of Microgrid Controllers: This standard established requirements for controllers, used to sense and manage microgrids. These requirements inform the manufacturing of controllers, and ultimately enable grid interoperability. NIST funding aided this standard’s development.

IEEE 2030.8 Standard for Testing Microgrid Controllers: This testing standard helps verify that microgrid controllers meet these requirements, and, thus, will work as intended. NIST funding aided this standard’s development.

IEEE 1547-2018 Standard for Interconnection and Interoperability of Distributed Energy Resources with Associated Electric Power Systems Interfaces: This standard ushers in a new era of improved performance for distributed energy resources, connected to the grid. NIST funding aided this standard’s development.

Today we break form from our normal custom of assessing conceptual movement in stabilized safety and sustainability standards for education settlements and, instead, venture into a domain that will inform nearly everything we do; and with gathering pace.

We begin with the action among the experts in the organizations listed below:

  1. National Institute of Standards and Technology (NIST):
    • NIST’s Post-Quantum Cryptography Standardization: NIST is working on standardizing cryptographic algorithms that are secure against quantum attacks. The goal is to ensure that data remains secure even with the advent of quantum computers. This involves selecting algorithms through an open competition, which began in 2016, and is still ongoing.
    • Quantum Information Program: NIST conducts research and develops standards related to quantum information science, including quantum computing, quantum communication, and quantum metrology.
  2. Quantum Economic Development Consortium (QED-C):
    • Formed as part of the National Quantum Initiative Act, QED-C aims to enable and grow the quantum industry in the U.S. It involves various stakeholders, including industry, academic institutions, and government agencies, working together to identify and address standards and other needs to foster a robust quantum ecosystem.
  3. National Quantum Initiative (NQI):
    • Established by the National Quantum Initiative Act in 2018, NQI coordinates efforts across multiple agencies, including NIST, the Department of Energy (DOE), and the National Science Foundation (NSF), to advance quantum information science. This includes the development of standards, infrastructure, and research to support quantum technologies.
  4. International Standards:
    • While primarily international, organizations like the International Telecommunication Union (ITU) and the International Organization for Standardization (ISO) have working groups focusing on quantum technologies. U.S. participation in these groups helps ensure that global standards align with U.S. interests and priorities.
  5. Federal Agencies and Research Programs:
    • The DOE, NSF, and other federal agencies fund research and development in quantum computing, which often includes aspects related to standards and best practices. For example, the DOE’s Quantum Information Science (QIS) Research Centers and NSF’s Quantum Leap Challenge Institutes.
  6. Industry-Led Initiatives:
    • Several industry consortia and companies are actively involved in developing quantum computing standards. Organizations like the IEEE have working groups focused on quantum computing and quantum communications standards.

Overall, the U.S. approach to quantum computing standards is multifaceted, involving federal agencies, industry consortia, academic research, and participation in international standard-setting bodies.

2024 Update to ASHRAE Position Statements

List of Titles, Scopes and Purposes of the ASHRAE Catalog

Public Review Draft Standards

As of the date of this post, no proposed revisions to the ASHRAE 90.4 have been released for public consultation.  Keep in mind that its normative reference — ASHRAE Standard 90.1: Energy Standard for Buildings Except Low-Rise Residential Buildings — is continually under revision; frequently appearing in electrical engineering design guidelines, construction specifications, commissioning and O&M titles in our industry and others.

ASHRAE 90.4 defines an alternate compliance path, specific to data centers, while the compliance requirements for “non-data center” components are contained in ASHRAE 90.1 .  The 90.4 structure also streamlines the ongoing maintenance process as well ensures that Standards 90.1 and 90.4 stay in their respective lanes to avoid any overlap and redundancies relating to the technical and administrative boundaries.  Updates to ASHRAE 90.1 will still include the alternate compliance path defined in ASHRAE 90.4. Conversely the 2022 Edition of 90.4-2022 refers to ASHRAE 90.1-2022; cross-referencing one another synchronously

Originally posted Summer 2020.

 

ASHRAE International has released four new addenda to its energy conservation consensus document ASHRAE 90.4-2016 Energy Standard for Data Centers.  This document establishes the minimum energy efficiency requirements of data centers for design and construction, for the creation of a plan for operation and maintenance and for utilization of on-site or off-site renewable energy resources.

It is a relatively new document more fully explained in an article published by ASHRAE in 2016 (Click here).   The addenda described briefly:

Addendum a  – clarifies existing requirements in Section 6.5 as well as introduce new provisions to encourage heat recovery within data centers.

Addendum b  – clarifies existing requirements in Sections 6 and 11 and to provide guidance for taking credit for renewable energy systems.

Addendum d  – a response to a Request for Interpretation on the 90.4 consideration of DieselRotary UPS Systems (DRUPS) and the corresponding accounting of these systems in the Electrical Loss Component (ELC). In crafting the IC, the committee also identified several marginal changes to 90.4 definitions and passages in Section 8 that would add further clarity to the issue. This addendum contains the proposed changes for that aim as well as other minor changes to correct spelling or text errors, incorporate the latest ELC values into Section 11, and to refresh information in the Normative Reference.

Addendum e adds language to Section 11 intended to clarify how compliance with Standard 90.4 can be achieved through the use of shared systems.

Comments are due September 6th.   Until this deadline you may review the changes and comment upon them by by CLICKING HERE
