Abstract: This paper presents a broad view of management of design and implementation of power systems for Data Centers. The paper outlines many challenges that are present because of the demanding requirements of Data Centers both in design and management, then introduces opportunities that recent technological advances have made possible. This paper presents several new approaches of ownership and responsibilities that directly affect financial viability of the Data Center.
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 hostedJanuary 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.
Proposed Addendum g makes changes to definitions were modified in section 3 and mandatory language in Section 6 to support the regulation of process heat and process ventilation was moved in the section for clarity. Other changes are added based on comments from the first public review including changes to informative notes.
Consultation closes June 4th
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:
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.

Education facility managers, energy conservation workgroups and sustainability professionals are encouraged to participate directly in the ASHRAE standard development process. Start at ASHRAE’s public commenting facility:
The ASHRAE catalog is a priority title in our practice. This title appears on the standing agenda of our Infotech sessions. See our CALENDAR for the next online meeting; open to everyone.
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:
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.
Education estate 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 standards-developing organizations aim to broaden their influence by entering the product standard and certification domain. Although our primary focus is on interoperability standards (within a system of interoperable products), we also consider market dynamics when product performance specifications are incorporated by reference into public law.
To paraphrase Marc Andreessen: “Building standards are eating the world and ASHRAE is eating building standards” (– Mike Anthony, University of Michigan). Just when you thought ASHRAE’s claim to energy regulation could not get any larger, it has recently appropriated everything *between* buildings in its scope — that means all above-ground pathway lighting, steam, hot water communication cabling tunnels, water pumps, fire protections systems; among others.
Best wiring safety practice for the illumination of educational settlement occupancies is scattered throughout the National Electrical Code with primary consideration for wiring fire safety:
Article 410 – Covers the installation of luminaires (fixtures), lampholders, and lamps, including requirements for wiring, grounding, and support.
The renovated Schwarzman Center at Yale now features dynamic new communal areas, a refreshed historic dining hall and eye-catching exterior lighting, enhancing the campus experience.
The command issued by the character Captain Jean-Luc Picard in the television series “Star Trek: The Next Generation” finds its way into the archive of photographs of Nobel Laureates consorting with politicians at the University of Michigan and elsewhere.

…”There’s not good math explaining forget the physics of it. Math explaining the behavior of complex systems yeah and that to me is both exciting and paralyzing like we’re at very early days of understanding you know how complicated and fascinating things emerge from simple rules…” — Peter Woit [1:16:00]
Since 1936 the Brown Jug has been the ancestral trough of generations of University of Michigan students and faculty — notably. Donald Glaser (inventor of the bubble chamber) and Samuel C. C. Ting (Nobel Laureate) whose offices at Randall Laboratory were a 2-minute walk around the corner from The Brown Jug. As the lore goes, the inspiration happened whilst watching beer bubbles one ordinary TGIF Friday.
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.
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,

The American National Standards Institute — the Global Secretariat for ISO — does not provide content management systems for its US Technical Advisory Groups. Because of the nascent committee, inspired by the work of Lee Webster at the University of Texas Medical Branch needed a content management system, we have been managing content on a Google Site facility on a University of Michigan host since 2014.Earlier this spring, the University of Michigan began upgrading its Google Sites facility which requires us to offload existing content onto the new facility before the end of June. That process is happening now. Because of this it is unwise for us to open the content library for this committee publicly. Respecting copyright, confidentiality of ISO and the US Technical Advisory Group we protect most recent content in the link below and invite anyone to click in any day at 15:00 (16:00) UTC. Our office door is open every day at this hour and has been for the better part of ten years.
“…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….”
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:
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.

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:
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.

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.
Transcripts of technical committee action during the 2026 revision (CMP-16) are linked below because they will inform our recommendations for the 2026 National Electrical Code. Keep in mind that the Technical Correlating Committee is moving content around the Code in order to make the NEC easier to use by experts.
The transcripts of technical committee action during the 2023 revision are linked below because they will inform our recommendations for the 2026 National Electrical Code.
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.
