Today we pick through the literature for best practice in recycling enterprises in education communities. We have been keeping pace with the evolution of regulations in this domain for over 15 years now. Much like the security zietgeist the number of organizations involved in standards setting and conformance will likely surprise you. It is a cross cutting topic with a growing body of expert agencies claiming some part of the domain.
We will also pick through a few representative legislative proposals. Use the login credentials at the upper right of our home page.

We have been keeping pace with the evolution of regulations in this domain for over 15 years now. Hydra-like growth in policy think tanks and standards-developing organizations expanding into this domain will likely surprise you. For example, in no particular order:
As in other domains, the private standards system competes with government “influencers” and incumbent proxies who make markets through legislation.
Specific requirements must be met for recycling to be economically feasible and environmentally effective. These include an adequate source of recyclates, a system to extract those recyclates from the waste stream, a nearby factory capable of reprocessing the recyclates, and a potential demand for the recycled products. These last two requirements are often overlooked—without both an industrial market for production using the collected materials and a consumer market for the manufactured goods, recycling is incomplete and in fact only “collection”.

We are observers in the development of a new ANSI accredited electronic equipment recycling standard produced with the leadership of NSF International; a Michigan-based standards developer (founded at the University of Michigan) not far from our own offices and one of the largest in the world.
The electronic recycling space is growing quickly — reaching far upstream the value chain into how electronic equipment is designed in the first place. An overview of the project is available in the link below:
This standard moved swiftly to market under NSF International’s continuous maintenance process. We bring it to the attention of the education facilities industry as a recommendation for lowering #TotalCostofOwnership. Participation as a User interest in American national standards development reduces “wheel reinvention” in which many recycling workgroups unnecessarily start from scratch, eliminates the need to attend costly workshops hosted by trade associations and significantly minimizes destructive competition.
This title is on the standing agenda of our Redivivus colloquium. Since our interest lies primarily with electrotechnology we collaborate with the IEEE Standards Association. See our CALENDAR for the next online meeting; open to everyone.
The fourth edition of ASHRAE Standard 90.4 was published in late 2025 (superseding the 2022 edition) and it provides leading practice for smaller enterprise level data centers as well as hyperscale campuses.
Key Highlights of the 2025 Edition
Establishes minimum energy efficiency requirements for the design, construction, operation, and maintenance of data centers.
Expanded sustainability scope: Goes beyond pure energy efficiency to explicitly include greenhouse gas emissions, water use, and broader resource impacts.
Maintains the performance-based approach using metrics like the Mechanical Load Component (MLC) and Electrical Loss Component (ELC), with refinements to make requirements more stringent.
Applies primarily to data centers with power density >20 W/ft² and IT loads >10 kW. It references ASHRAE 90.1 for non-data-center elements (envelope, lighting, etc.).
This marks a clear evolution toward decarbonization and resource efficiency, especially important for AI-driven hyperscale data centers.
Recent Developments (2025–2026)
Addendum b to the 2022 edition was approved in September 2025, providing clarifications for phased or modular data center designs.
The 2024 IECC now references ASHRAE 90.4-2022 (Sections 6 and 8) as a compliance path for data centers.
ASHRAE continues to advocate for wider adoption of 90.4 in state and local energy codes.
The Standing Standard Project Committee (SSPC 90.4) remains active with working groups on mechanical, electrical, ESG, and marketing aspects.
Data centers are among the fastest-growing energy consumers globally due to AI, cloud computing, and digital infrastructure. ASHRAE 90.4 was created because traditional building codes do not adequately address their unique high-density, mission-critical nature.
The 2025 edition’s inclusion of emissions and water use reflects increasing industry and regulatory pressure on data center environmental footprints.
This title establishes minimum energy efficiency requirements for data centers; a permanent fixture in all education communities now undergoing a virtual +∞ asymptotic spike in generative intelligence transformation in ℝ³. At the moment this title is stable but can be revised in 30-90 day consultation cycles which will make it the dominant standard compared with IEEE and NFPA titles which move on a 3 to 5 year revision cadence.
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
Links to noteworthy coverage from expert agencies on the 2022 revisions:
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.
Comments are due September 6th. Until this deadline you may review the changes and comment upon them by by CLICKING HERE
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:

After athletic arena life safety obligations are met (governed legally by NFPA 70, NFPA 101, NFPA 110, the International Building Code and possibly other state adaptations of those consensus documents incorporated by reference into public safety law) business objective standards may come into play.For almost all athletic facilities, the consensus documents of the Illumination Engineering Society[1], the Institute of Electrical and Electronic Engineers[2][3] provide the first principles for life safety. For business purposes, the documents distributed by the National Collegiate Athletic Association inform the standard of care for individual athletic arenas so that swiftly moving media production companies have some consistency in power sources and illumination as they move from site to site. Sometimes concepts to meet both life safety and business objectives merge.
During hockey season the document linked below provides information to illumination designers and facility managers:
Athletic programs are a significant source of revenue and form a large part of the foundation of the brand identity of most educational institutions in the United States. We focus primarily upon the technology standards that govern the safety, performance and sustainability of these enterprises. We collaborate very closely with the IEEE Education & Healthcare Facilities Committee where subject matter experts in electrical power systems meet 4 times each month in the Americas and Europe.
See our CALENDAR for our next colloquium on Sport facility codes and standards. We typically walk through the safety and sustainability concepts in play; identify commenting opportunities; and find user-interest “champions” on the technical committees who have a similar goal in lowering #TotalCostofOwnership.

Our tenure in the 2026 National Electrical Code will result in at least a 10 percent reduction in the cost of building premise wiring — (mostly in the feeder power chain) — in healthcare facilities; based on the results of last month’s meeting of Code Making Panel 15.
Assuming electrical power infrastructure is 15 percent of in a $920 million facility like this (excluding interior moveable fixtures), that would have meant an approximate $14 million reduction in cost. That cost savings cannot be realized because it was designed to an earlier version of the National Electrical Code.
