Brown University Electrical Design Criteria | Information Technology Resources Policy
The University of Michigan has supported the voice of the United States education facility industry since 1993 — the second longest tenure of any voice in the United States. That voice has survived several organizational changes but remains intact and will continue its Safer-Simpler-Lower Cost-Longer Lasting priorities on Code Panel 3 in the 2029 Edition.
Today, during our customary “Open Door” teleconference we will examine the technical concepts under the purview of Code Panel 3; among them:
Article 206 Signaling Circuits
Article 300 General Requirements for Wiring Methods and Materials
Article 335 Instrumentation Tray Cable
Article 590 Temporary Installations
Chapter 7 Large sections of limited energy cabling for signaling and information technology
Chapter 9 Conductor Properties Tables 11A & B, Tables 12A&B
Public Input on the 2029 Edition will be received until April 9, 2026.
2024 Update to ASHRAE Position Statements
List of Titles, Scopes and Purposes of the ASHRAE Catalog
The parent title of this standard is ASHRAE Standard 90.1: Energy Standard for Buildings Except Low-Rise Residential Buildings and 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

This title resides on the standing agenda of our Infotech 400 colloquium; hosted several times per year and as close coupled with the annual meetings of ASHRAE International as possible. Technical committees generally meet during these meetings make decisions about the ASHRAE catalog. The next all committee conference will be hosted January 20-24, 2024 in Chicago. As always we encourage education industry facility managers, energy conservation workgroups and sustainability professionals to participate directly in the ASHRAE consensus standard development process. It is one of the better facilities out there.

Update: February 10, 2023
The most actively managed consensus standard for data center energy supply operating in education communities (and most others) is not published by the IEEE but rather by ASHRAE International — ASHRAE 90.4 Energy Standard for Data Centers (2019). It is not required to be a free access title although anyone may participate in its development. It is copyrighted and ready for purchase but, for our purpose here, we need only examine its scope and purpose. A superceded version of 90.4 is available in the link below:
Third ISC Public Review Draft (January 2016)
Noteworthy: The heavy dependence on IEEE power chain standards as seen in the Appendix and Chapter 8. Recent errata are linked below:
We provide the foregoing links for a deeper dive “into the weeds”. Another addendum has been released for consultation; largely administrative:
ASHRAE 90.4 | Pages 60-61 | Consultation closes January 15, 2023.
It is likely that the technical committee charged with updating this standard are already at work preparing an updated version that will supercede the 2019 Edition. CLICK HERE for a listing of Project Committee Interim Meetings.
We maintain many titles from the ASHRAE catalog on the standing agenda of our Mechanical, Energy 200/400, Data and Cloud teleconferences. See our CALENDAR for the next online meeting; open to everyone.
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

Federal Energy Regulatory Commission: Electrical Resource Adequacy
NARUC Position on NFPA (NEC) and IEEE (NESC) Harmonization
The standard of care for electrical safety at high and low voltage is set by both the NEC and the NESC. There are gaps, however (or, at best “gray areas”) — the result of two technical cultures: utility power culture and building fire safety culture. There is also tradition. Local system conditions and local adaptation of regulations vary. Where there is a gap; the more rigorous requirement should govern safety of the public and workers.
The 2023 National Electrical Safety Code (NESC)– an IEEE title often mistaken for NFPA’s National Electrical Code (NEC) — was released for public use about six months ago; its normal 5-year revision cycle interrupted by the circumstances of the pandemic. Compared with the copy cost of the NEC, the NESC is pricey, though appropriate for its target market — the electric utility industry. Because the 2023 revision has not been effectively “field tested” almost all of the available support literature is, effectively, “sell sheets” for pay-for seminars and written by authors presenting themselves as experts for the battalions of litigators supporting the US utility industry. Without the ability to sell the NESC to prospective “insiders” the NESC would not likely be commercial prospect for IEEE. As the lawsuits and violations and conformance interests make their mark in the fullness of time; we shall see the 2023 NESC “at work”.

We collaborate closely with the IEEE Education & Healthcare Facilities Committee (IEEE E&H) to negotiate the standard of care for power security on the #SmartCampus since many campus power systems are larger than publicly regulated utilities. Even when they are smaller, the guidance in building the premise wiring system — whether the premise is within a building, outside the building (in which the entire geography of the campus footprint is the premise), is inspired by IEEE Standards Association administrated technical committees.
Today we begin a list of noteworthy changes to be understood in the next few Power colloquia. See our CALENDAR for the next online meeting.

Several proposals recommending improvements to the 2017 National Electrical Safety Code (NESC) were submitted to the IEEE subcommittees drafting the 2022 revision of the NESC. Some of the proposals deal with coordination with the National Electrical Code — which is now in its 2023 revision cycle. Keep in mind that that NESC is revised every 5 years at the moment; the NEC is revised every 3 years.
The original University of Michigan standards advocacy enterprise has been active in writing the NESC since the 2012 edition and set up a workspace for use by electrical professionals in the education industry. We will be using this workspace as the 2022 NESC continues along its developmental path:
The revision schedule — also revised in response to the circumstances of the pandemic — is linked below::
NESC 2023 Edition Revision Schedule*






The NESC is a standing item on the 4-times monthly teleconferences of the IEEE Education & Healthcare Facilities committee. The next online meeting is shown on the top menu of the IEEE E&H website:
We have a copy of the first draft of the 2023 NESC and welcome anyone to join us for an online examination during any of Power & ICT teleconferences. See our CALENDAR for the next online meeting.
Business unit leaders, facility managers and electrical engineers working in the education facilities industry may be interested in the campus power system reliability database. Forced outages on large research campuses, for example, can have enterprise interruption cost of $100,000 to $1,000,000 per minute. The campus power system forced outage database discriminates between forced outages attributed to public utility interruptions and forced outages attributed to the university-owned power system. The E&H committee will convey some of the discipline applied by the IEEE 1366 technical committee into its study of campus power systems and, ultimately, setting a benchmark for the standard of care for large university power systems.
* The IEEE changed the nominal date of the next edition; likely owed to pandemic-related slowdown typical for most standards developing organizations.

Here we shift our perspective 120 degrees to understand the point of view of the Producer interest in the American national standards system (See ANSI Essential Requirements). The title of this post draws from the location of US and European headquarters. We list proposals by a successful electrical manufacturer for discussion during today’s colloquium:
2026 National Electrical Code
CMP-1: short circuit current ratings, connections with copper cladded aluminum conductors, maintenance to be provided by OEM, field markings
CMP-2: reconditioned equipment, receptacles in accessory buildings, GFCI & AFCI protection, outlet placement generally, outlets for outdoor HVAC equipment(1)
(1) Here we would argue that if a pad mount HVAC unit needs service with tools that need AC power once every 5-10 years then the dedicated branch circuit is not needed. Many campuses have on-site, full-time staff that can service outdoor pad mounted HVAC equipment without needing a nearby outlet. One crew — two electricians — will run about $2500 per day to do anything on campus.
CMP-3: No proposals
CMP-4: solar voltaic systems (1)
(1) Seems reasonable – spillover outdoor night time lighting effect upon solar panel charging should be identified.
CMP-5: Administrative changes only
CMP-6: No proposals
CMP-7: Distinction between “repair” and “servicing”
CMP-8: Reconditioned equipment
CMP-9: Reconditioned equipment
CMP-10: Short circuit ratings, service disconnect, disconnect for meters, transformer secondary conductor, secondary conductor taps, surge protective devices, disconnecting means generally, spliced and tap conductors, more metering safety, 1200 ampere threshold for arc reduction technology, reconditioned surge equipment shall not be permitted, switchboard short circuit ratings

CMP-12: Lorem
CMP-13: Lorem
