Energy Standard for Data Centers

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

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.

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   A superceded version of 90.4 is available in the link below: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:

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

NARUC Position on NFPA (NEC) and IEEE (NESC) Harmonization

The standard of care for electrical safety at high and low voltage is set by both the NEC and the NESC. There are gaps, however (or, at best “gray areas”) — the result of two technical cultures: utility power culture and building fire safety culture. There is also tradition. Local system conditions and local adaptation of regulations vary. Where there is a gap; the more rigorous requirement should govern safety of the public and workers.

The 2023 National Electrical Safety Code (NESC)– an IEEE title often mistaken for NFPA’s National Electrical Code (NEC) — was released for public use about six months ago; its normal 5-year revision cycle interrupted by the circumstances of the pandemic.   Compared with the copy cost of the NEC, the NESC is pricey, though appropriate for its target market — the electric utility industry.  Because the 2023 revision has not been effectively “field tested” almost all of the available support literature is, effectively, “sell sheets” for pay-for seminars and written by authors presenting themselves as experts for the battalions of litigators supporting the US utility industry.  Without the ability to sell the NESC to prospective “insiders” the NESC would not likely be commercial prospect for IEEE.   As the lawsuits and violations and conformance interests make their mark in the fullness of time; we shall see the 2023 NESC “at work”.

CP5606 Provides new definitions of Communication Lines to help ensure that Fault Managed Power Systems (FMPS)
circuits used for the exclusive powering of communications equipment are clearly identified as communications lines
and makes an explicit connection to Rule 224B where the applicable rules for such powering circuits are found.
https://ieee-sa.imeetcentral.com/p/eAAAAAAASPXpAAAAAFfvWIs

CP5607 The addition of this exception permits cables containing Fault Managed Power System (FMPS) circuits used for
the exclusive powering of communications equipment to be installed without a shield.

August 5, 2022

We collaborate closely with the IEEE Education & Healthcare Facilities Committee (IEEE E&H) to negotiate the standard of care for power security on the #SmartCampus  since many campus power systems are larger than publicly regulated utilities.  Even when they are smaller, the guidance in building the premise wiring system — whether the premise is within a building, outside the building (in which the entire geography of the campus footprint is the premise), is inspired by IEEE Standards Association administrated technical committees.

Northeast Community College | Norfolk, Nebraska

Today we begin a list of noteworthy changes to be understood in the next few Power colloquia.  See our CALENDAR for the next online meeting.

  1. New rules 190 through 195 cover photovoltaic generating stations.  Rule 116c adds an exception for short lengths of insulated power cables and short-circuit protection if the situation involves fewer than 1,000 volts.
  2. Rule 320B has been revised to clarify separations that apply to communications and supply in different conduit systems.
  3. Table 410-4 is based on the latest arc flash testing on live-front transformers.
  4. Rule 092A adds an exception allowing protection, control, and safety battery systems to not be grounded.
  5. Rules 234 B1, C1, D1 were revised to better present vertical and horizontal wind clearances, and to coordinate requirements with the new Table 234-7.
  6. Rule 120A was revised to provide correction factors for clearances on higher elevations.
  7. Table 253-1 has been revised to reduce the load factor for fiber-reinforced polymer components under wire tension—including dead ends—for Grade C construction.
  8. Rule 410A now requires a specific radio-frequency safety program for employees who might be exposed.
  9. In the Clearances section, as well as in the specification of the Grade of Construction in Table 242-1, the Code further clarifies the use of non-hazardous fiber optic cables as telecom providers continue to expand their networks.
  10. Revisions in the Strength & Loading sections include modified Rule 250C, which addresses extreme wind loading for overhead lines. Two wind maps are now provided instead of the previous single one. A map for Grade B, the highest grade of construction, with a Mean Recurrence Interval (MRI) of 100 years (corresponding to a one percent annual probability of occurrence) is provided in place of the previous 50–90-year MRI map. For Grade C construction, a separate 50-year MRI (two percent annual probability of occurrence) map is now provided. In the previous Code, a factor was applied to the 50–90-year MRI map for application to Grade C.
  11. Changes were also made to the method of determining the corresponding wind loads, consistent with the latest engineering practices as an example of a Code revision focused on public safety, the ground end of all anchor guys adjacent to regularly traveled pedestrian thoroughfares, such as sidewalks, and similar places where people can be found must include a substantial and conspicuous marker to help prevent accidents. The previous Code did not require the marking of every such anchor guy.
  12. Significant revisions were made in Section 14 covering batteries. Previous editions of the code were based on lead-acid technology and batteries only used for backup power. The 2023 Code incorporates the new battery technologies and addresses energy storage and backup power.
  13. A new Section 19 of the code covers photovoltaic generating stations, with sections addressing general codes, location, grounding configurations, vegetation management, DC overcurrent protection, and DC conductors. These new rules accommodate large-scale solar power projects.
  14. In the Clearances section, all rules for wireless antenna structures have been consolidated in the equipment section (Rule 238 and 239), which makes the Code more user-friendly.
  15. A new subcommittee was created focusing on generating stations, with the original subcommittee continuing to address substations.
  16. A working group is investigating Fault Managed Power Systems (FMPS) cables as the technology may be used for 5G networks. The team is looking at possible impacts, including clearances and work rules.

 

February 18, 2021

 

Several proposals recommending improvements to the 2017 National Electrical Safety Code (NESC) were submitted to the IEEE subcommittees drafting the 2022 revision of the NESC.   Some of the proposals deal with coordination with the National Electrical Code — which is now in its 2023 revision cycle.  Keep in mind that that NESC is revised every 5 years at the moment; the NEC is revised every 3 years.

The original University of Michigan standards advocacy enterprise has been active in writing the NESC since the 2012 edition and set up a workspace for use by electrical professionals in the education industry.   We will be using this workspace as the 2022 NESC continues along its developmental path:

IEEE 2022 NESC Workspace

The revision schedule — also revised in response to the circumstances of the pandemic — is linked below::

NESC 2023 Edition Revision Schedule*

 

The NESC is a standing item on the 4-times monthly teleconferences of the IEEE Education & Healthcare Facilities committee.  The next online meeting is shown on the top menu of the IEEE E&H website:

IEEE E&H Committee

We have a copy of the first draft of the 2023 NESC and welcome anyone to join us for an online examination during any of Power & ICT teleconferences.  See our CALENDAR for the next online meeting.

Business unit leaders, facility managers and electrical engineers working in the education facilities industry may be interested in the campus power system reliability database.   Forced outages on large research campuses, for example, can have enterprise interruption cost of $100,000 to $1,000,000 per minute.    The campus power system forced outage database discriminates between forced outages attributed to public utility interruptions and forced outages attributed to the university-owned power system.   The E&H committee will convey some of the discipline applied by the IEEE 1366 technical committee into its study of campus power systems and, ultimately, setting a benchmark for the standard of care for large university power systems.

 

 

* The IEEE changed the nominal date of the next edition; likely owed to pandemic-related slowdown typical for most standards developing organizations.

Here we shift our perspective 120 degrees to understand the point of view of the Producer interest in the American national standards system (See ANSI Essential Requirements).  The title of this post draws from the location of US and European headquarters.  We list proposals by a successful electrical manufacturer for discussion during today’s colloquium:

2026 National Electrical Code

CMP-1: short circuit current ratings, connections with copper cladded aluminum conductors, maintenance to be provided by OEM, field markings

CMP-2: reconditioned equipment, receptacles in accessory buildings, GFCI & AFCI protection, outlet placement generally, outlets for outdoor HVAC equipment(1)

(1) Here we would argue that if a pad mount HVAC unit needs service with tools that need AC power once every 5-10 years then the dedicated branch circuit is not needed.  Many campuses have on-site, full-time staff that can service outdoor pad mounted HVAC equipment without needing a nearby outlet.  One crew — two electricians — will run about $2500 per day to do anything on campus.

CMP-3: No proposals

CMP-4: solar voltaic systems (1)

(1) Seems reasonable – spillover outdoor night time lighting effect upon solar panel charging should be identified.

CMP-5: Administrative changes only

CMP-6: No proposals

CMP-7: Distinction between “repair” and “servicing”

CMP-8: Reconditioned equipment

CMP-9: Reconditioned equipment

CMP-10: Short circuit ratings, service disconnect, disconnect for meters, transformer secondary conductor, secondary conductor taps, surge protective devices, disconnecting means generally, spliced and tap conductors, more metering safety, 1200 ampere threshold for arc reduction technology, reconditioned surge equipment shall not be permitted, switchboard short circuit ratings

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:

READ ONLY Version of 2022 ASHRAE 90.1

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.

Why Software is Eating the World

* 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.

Luminaires, Lampholders, and Lamps

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.
  • Article 210 – Covers branch circuit requirements, including those for lighting circuits in dwellings and commercial buildings.
  • Article 220 – Provides guidelines for calculating lighting loads.
  • Article 225 – Addresses outside lighting installations.
  • Article 240 – Covers overcurrent protection for lighting circuits.
  • Article 250 – Deals with grounding and bonding, which is essential for lighting circuits.
  • Article 300 – Covers general wiring methods that apply to lighting circuits.

We have done a fair amount of work on this topic over the years, including writing the chapter on campus outdoor lighting for the soon-to-be-released IEEE 3001.9 Recommended Practice for the Design of Power Systems Supplying Lighting Systems in Commercial and Industrial Facilities.

ISO Technical Committees | ANSI (U.S. Participation in ISO Activities)

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.

Scope

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.

Today we feature the catalog of the Illumination Engineering Society — one of the first names in standards-setting in illumination technology, globally* with particular interest in its leading title IES LP-1 | LIGHT + DESIGN Lighting Practice: Designing Quality Lighting for People and Buildings.

From its prospectus:

“…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:

IES Standards Open for Public Review

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.   Use the login credentials at the upper right of our home page to join us.
