"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

Data centers in colleges and universities are crucial for supporting the extensive technological infrastructure required for modern education and research. These centers house critical servers and storage systems that manage vast amounts of data, ensuring reliable access to academic resources, administrative applications, and communication networks. They enable the secure storage and processing of sensitive information, including student records, faculty research, and institutional data.

Uptime Institute Tier Classification

Moreover, data centers facilitate advanced research by providing the computational power needed for data-intensive studies in fields like bioinformatics, climate science, and artificial intelligence. They support virtual learning environments and online course management systems, essential for the increasingly prevalent hybrid and online education models. Efficient data centers also contribute to campus sustainability goals by optimizing energy use through modern, eco-friendly technologies.

ANSI/TIA 942 Data Center Infrastructure Standard

Additionally, robust data center infrastructure enhances the university’s ability to attract top-tier faculty and students by demonstrating a commitment to cutting-edge technology and resources. They also play a vital role in disaster recovery and business continuity, ensuring that educational and administrative functions can resume quickly after disruptions. Overall, data centers are integral to the academic mission, operational efficiency, and strategic growth of colleges and universities.

We have followed development of the technical standards that govern the success of these “installations” since 1993; sometimes nudging technical committees — NFPA, IEEE, ASHRAE, BICSI and UL.   The topic is vast and runs fast so today we will review, and perhaps respond to, the public consultations that are posted on a near-daily basis.  Use the login credentials at the upper right of our home page.

Steeplechase Water Jump

March 11, 2025

No Comments

The steeplechase event requires a combination of speed, endurance, and jumping ability, as athletes must clear the barriers while maintaining their pace and negotiating the water jump. The rules and specifications for the steeplechase event are set by the International Association of Athletics Federations the governing body for the sport of athletics (track and field) worldwide; with minor adaptations by the NCAA for intercollegiate competition.

Emma Coburn | University of Colorado Boulder

The steeplechase is a distance race with barriers and a water pit that athletes must clear during the race.  According to the NCAA Track and Field and Cross Country rulebook, the standards for the steeplechase water jump are as follows:

  1. Length: The water pit must be at least 3.66 meters (12 feet) long.
  2. Width: The water pit must be at least 3.66 meters (12 feet) wide.
  3. Depth: The water pit must have a minimum depth of 0.7 meters (2 feet 4 inches) and a maximum depth of 0.9 meters (2 feet 11 inches).
  4. Slope: The slope of the water pit must not exceed 1:5, meaning that for every 5 meters in length, the water pit can rise by no more than 1 meter in height.
  5. Barrier: The water pit must be preceded by a solid barrier that is 91.4 cm (3 feet) high. Athletes are required to clear this barrier before landing in the water pit.

These standards may be subject to change and may vary depending on the specific NCAA division (Division I, Division II, or Division III) and other factors such as venue requirements. Therefore, it’s always best to refer to the official NCAA rules and regulations for the most up-to-date and accurate information on the steeplechase water jump standards in NCAA competitions.

Consulting-Specifying Engineer (March 4, 2025): Why and how to adopt the IECC for energy-efficient designs

2024 Update to ASHRAE Position Statements

List of Titles, Scopes and Purposes of the ASHRAE Catalog

Public Review Draft Standards

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

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:

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

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.

“Bookwheel” Early Data Center

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.

The current version of NFPA 70 is linked below:

2023 National Electrical Code

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.

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.
