Group B Proposed Changes 2024 Editions Complete Monograph (2630 Pages)
The International Code Council bibliography of elevator safety practice incorporates titles published by American Society of Mechanical Engineers, the National Fire Protection Association and the Institute of Electrical and Electronic Engineers. The relevant section of the International Building Code is therefore relatively short and linked below.

Comments on changes to the Group A tranche of titles will be heard in Long Beach California, October 23-31st.
Elevator Safety Code
Elevator, escalator and moving walk systems are among the most complicated systems in any urban environment, no less so than on the #WiseCampus in which many large research universities have 100 to 1000 elevators to safely and economically operate, service and continuously commission. These systems are regulated heavily at state and local levels of government and have oversight from volunteers that are passionate about their work.
These “movement systems” are absorbed into the Internet of Things transformation. Lately we have tried to keep pace with the expansion of requirements to include software integration professionals to coordinate the interoperability of elevators, lifts and escalators with building automation systems for fire safety, indoor air quality and disaster management. Much of work requires understanding of the local adaptations of national building codes.
Some university elevator O&M units use a combination of in-house, manufacturer and standing order contractors to accomplish their safety and sustainability objectives.
In the United States the American Society of Mechanical Engineers is the dominant standards developer of elevator and escalator system best practice titles; its breakdown of technical committees listed in the link below:
C&S Connect: ASME Proposals Available for Public Review
Public consultation on a new standard for electrical inspector qualifications closes May 27th.
ASME A17.7/CSA B44.7 – 20XX, Performance-based code for elevators and escalators (280 pages)
Safety Code for Existing Elevators and Escalators
Guide for Inspection of Elevators, Escalators, and Moving Walks
Guide for Elevator Seismic Design
As always, we encourage facility managers, elevator shop personnel to participate directly in the ASME Codes & Standards development process. For example, it would be relatively easy for our colleagues in the Phoenix, Arizona region to attend one or more of the technical committee meetings; ideally with operating data and a solid proposal for improving the A17 suite.

Carnegie-Mellon: Planning & Design Considerations for Data Centers
University of Kansas Data Center and Server Room Standards
Power Distribution Units (PDUs) are critical in data centers, serving as the backbone for reliable power management. They distribute electricity from the main power source to servers, networking equipment, and other devices, ensuring consistent and stable power delivery.
PDUs offer features like load balancing, surge protection, and remote monitoring, which optimize energy efficiency and prevent outages. By providing multiple outlets and circuit protection, they safeguard expensive equipment from power fluctuations. Advanced PDUs enable real-time data tracking, aiding in capacity planning and fault detection.
Ultimately, PDUs ensure uptime, operational efficiency, and scalability in data centers. We track, and sometimes participate, in the standards setting for these organizations develop the key standards that govern PDU design, safety, efficiency, and interoperability, influencing global manufacturing compliance:
UL (Underwriters Laboratories): Establishes safety standards like UL 60950-1 for IT equipment, ensuring PDUs prevent hazards in high-density environments.
IEC (International Electrotechnical Commission): Develops core electrical standards such as IEC 60950-1 and IEC 62368-1 for low-voltage safety and audio/video/IT equipment, critical for PDU power handling.
ENERGY STAR (U.S. EPA): Sets efficiency benchmarks for PDUs, promoting low-loss designs to minimize data center energy waste (up to 12% savings).Related:

What Happens When Data Centers Come to Town
Terry Nguyen | BA Public Policy

Introduction. [Abstract]. The rapid growth of data centers, with their enormous energy and water demands, necessitates targeted policy interventions to mitigate environmental impacts and protect local communities. To address these issues, states with existing data center tax breaks should adopt sustainable growth policies for data centers, mandating energy audits, strict performance standards, and renewable energy integration, while also requiring transparency in energy usage reporting. “Renewable energy additionality” clauses should ensure data centers contribute to new renewable capacity rather than relying on existing resources. If these measures prove insufficient, states should consider repealing tax breaks to slow unsustainable data center growth. States without tax breaks should avoid such incentives altogether while simultaneously implementing mandatory reporting requirements to hold data centers accountable for their environmental impact. Broader measures should include protecting local tax revenues for schools, regulating utility rate hikes to prevent cost-shifting to consumers, and aligning data center energy demands with state climate goals to avoid prolonging reliance on fossil fuels.

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.

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.

With thanks to Richard Robben, President of True North Facility Management, the pledges to fund the NFPA Fire Protection Foundation Project: Evaluation of Electrical Feeder and Branch Circuit Loading accumulated to the requisite $24,000 to begin Phase I of two phases of a project originally begun by the University of Michigan to bring the National Electrical Code (NFPA 70) in line with federal energy conservation regulations that incorporate by reference the International Energy Conservation Code.
NFPA 70 is one of the most widely used standards for electrotechnology in the world. The University of Michigan began assertive advocacy on behalf of the US education industry in the NFPA suite in 1996 and that advocacy has expanded globally under two different private organizations: See About
Phase I is now completed. The Phase I Final Report (with public comments) is available in the links below:

Intellectual Property
It is impossible to overestimate the sensitivity of this topic but poke at it, we will. At the moment, the less written here; the better. Much of this domain is outside our wheelhouse; though it has settled on a few first principles regarding patents, trademarks and copyrights relevant to the user-interest we describe in our ABOUT.
Many large research universities have a watchdog guarding its intellectual property and trying to generate income from it, and; of course, for branding. We will dwell on salient characteristics of the intellectual property domain with which we reckon daily — highlighting the market actors and the standards they have agreed upon.
Additionally, technical standards developers are generally protected by copyright law, as the standards they create are typically considered original works of authorship that are subject to copyright protection. In the United States, the Copyright Act of 1976 provides copyright protection for original works of authorship, which includes technical standards. This means that the developers of technical standards have the exclusive right to reproduce, distribute, and create derivative works based on their standards, and others must obtain permission or a license to use or reproduce the standards.
Some technical standards may be subject to certain exemptions or limitations under copyright law. In the United States, there is a doctrine called “fair use” that allows for limited use of copyrighted works for purposes such as criticism, comment, news reporting, teaching, scholarship, or research, without the need for permission or a license from the copyright owner. Almost everything we do at Standards Michigan falls under the fair use doctrine. This is why we have no search feature and most pages are protected. If we err in this; let us know.
