Abstract. The analysis presented in this paper indicates that the FM radio spectrum is underutilized in the areas of the continental United States that have a population of 100000 or less. These locations have vacant FM radio spectrum of at least 13 MHz with sufficient spectrum spacing between adjacent FM radio channels. The spectrum spacing provides the required bandwidth for data transmission and provides enough bandwidth to minimize interference introduced by neighboring predicted and unpredicted FM radio stations and other low-power short-range Internet of Thing (IoT) devices. To ensure that low-power short-range IoT devices maintain reliable communications vacant radio spectrum, such as the FM radio spectrum in these areas, will need to be used through cognitive radio.

Starting 2023 we break down our coverage of education community energy codes and standards into two tranches:
Energy 200: Codes and standards for building premise energy systems. (Electrical, heating and cooling of the building envelope)
Energy 300: Codes and standards that support the energy systems required for information and communication technology
Energy 400: Codes and standards for energy systems between campus buildings. (District energy systems including interdependence with electrical and water supply)
A different “flavor of money” runs through each of these domains and this condition is reflected in best practice discovery and promulgation. Energy 200 is less informed by tax-free (bonded) money than Energy 400 titles.
Some titles cover safety and sustainability in both interior and exterior energy domains so we simply list them below:
ASME A13.1 – 20XX, Scheme for the Identification of Piping Systems | Consultation closes 6/20/2023
ASME Boiler Pressure Vessel Code
ASME BPVC Codes & Standards Errata and Notices
ASHRAE International 90.1 — Energy Standard for Buildings Except Low-Rise Residential Buildings
2018 International Green Construction Code® Powered by Standard 189.1-2017
NFPA 855 Standard for the Installation of Stationary Energy Storage Systems
IEEE Electrical energy technical literature
ASTM Energy & Utilities Overview
Underwriters Laboratories Energy and Utilities
There are other ad hoc and open-source consortia that occupy at least a niche in this domain. All of the fifty United States and the Washington DC-based US Federal Government throw off public consultations routinely and, of course, a great deal of faculty interest lies in research funding.

“DIFFER” is a research institute domiciled at TU/e that is focused on advancing the development of sustainable energy technologies, such as fusion energy and solar fuels. It conducts fundamental research on plasma physics and materials science to understand the behavior of matter at extremely high temperatures and under extreme conditions.
DIFFER also collaborates with universities, research institutions, and industry partners to translate their research into practical applications. The institute’s ultimate goal is to develop new and innovative solutions to meet the world’s growing demand for energy while reducing greenhouse gas emissions and environmental impact.
Among its findings and recommendations: “Electrochemical Production of Ammonia from Renewable Energy: A Thermodynamic Analysis” published in the Journal of The Electrochemical Society in 2018, which evaluated the thermodynamic feasibility of using renewable energy to produce ammonia, an important fertilizer, through electrochemical processes.
N.B. Ammonia can be deployed for energy conservation purposes in various ways, such as:
However, it is worth noting that the deployment of ammonia for energy conservation purposes requires the development of suitable technologies for its production, transportation, and storage, as well as the necessary infrastructure to support its use.

No public consultations have been released on this title as of March 21, 2024.
As of the date of this post, no proposed revisions to the ASHRAE 90.4 have been released for public consultation. Links to noteworthy coverage from expert agencies on the 2022 revisions:
HPC Data Center Cooling Design Considerations
ASHRAE standard 90.4 updates emphasize green energy
ASHRAE updated its standard for data centers
How to Design a Data Center Cooling System for ASHRAE 90.4
Designing a Data Center with Computer Software Modeling
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.
Start at ASHRAE’s public commenting facility:
Online Standards Actions & Public Review Drafts
Update: May 30, 2023
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:
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

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.
The current version of NFPA 70 is linked below:
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.
Code‐Making Panel 12 Public Input Report
Code-Making Panel 12 Public Comment Report
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.
Today we review the codes and standards that apply to the instructional and research facilities that support nursing science and practice. There is no single organization with a best practice catalog as there are in other disciplines we follow. Best practice is inspired by the inherited wisdom of practitioners, faculty and students who work alongside other members of healthcare provider teams.
