Abstract: This paper presents a broad view of management of design and implementation of power systems for Data Centers. The paper outlines many challenges that are present because of the demanding requirements of Data Centers both in design and management, then introduces opportunities that recent technological advances have made possible. This paper presents several new approaches of ownership and responsibilities that directly affect financial viability of the Data Center.
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 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.

“Europe today has little desire to reproduce itself, fight for itself or even take its own side in a argument. By the end of the lifespans of most people currently alive, Europe will not be Europe and the peoples of Europe will have lost the only place in the world we had to call home”
Large European universities such as Rijksuniversiteit Groningen are integrated into the fabric of the surrounding city. There are several ways in which this integration takes place:
Physical location: Many European universities are located in the heart of the city, often in historic buildings that have been repurposed for educational use. This central location means that the university is easily accessible to students and the general public, and that it is often surrounded by other cultural institutions, such as museums, theaters, and libraries.
Student life: The presence of a large student population can have a significant impact on the city’s culture and economy. Many European cities have developed a vibrant student culture, with cafes, bars, and other venues catering to the needs and interests of young people. This can help to create a sense of community between the university and the city, and can also bring economic benefits to local businesses.
Research and innovation: Large European universities are often at the forefront of research and innovation, and they can be important drivers of economic growth in the surrounding region. Many universities work closely with local businesses and industries, and they may also collaborate with other universities and research institutions in the area.
Cultural exchange: Universities can be important centers of cultural exchange, both for international students and for local residents. Many European universities offer language classes and other cultural programs that are open to the public, and they may also host lectures, concerts, and other events that are designed to promote cross-cultural understanding.
Overall, the integration of large European universities into the city is a complex and multifaceted process that can have a significant impact on the social, cultural, and economic life of the surrounding region.
The origin of brown cafés can be traced back to the 17th century, during the Dutch Golden Age. At that time, the Netherlands was a prosperous and influential trading nation, and Amsterdam was a bustling city with a thriving port. Sailors, merchants, and locals needed places to socialize, relax, and conduct business, leading to the emergence of taverns and pubs.
The term “brown café” is believed to have originated from the brownish stains that formed on the walls and ceilings due to tobacco smoke, candle soot, and other atmospheric elements. These stains gave the cafés a distinct, cozy ambiance and a sense of history.
Brown cafés became an integral part of Dutch culture, serving as communal gathering spots for people of all walks of life. They were places where locals would meet friends, engage in conversations, enjoy a drink, and sometimes play board games like chess or backgammon. Over time, brown cafés became associated with an authentic, unpretentious, and relaxed atmosphere, attracting both locals and tourists.
The unique charm of brown cafés lies in their preserved historical interiors, with old wooden furniture, dim lighting, and a wide selection of local beers and spirits. Many brown cafés still retain their original character, transporting visitors back in time and providing a cozy retreat from the hustle and bustle of modern life.
While the concept of brown cafés originated in the Netherlands, similar types of establishments can also be found in other European countries, such as Belgium and parts of Germany. However, the term “brown café” is primarily associated with the Dutch tradition of cozy, atmospheric, and convivial drinking establishments.
The largest planetarium on a U.S. college or university campus is the Fiske Planetarium at the University of Colorado Boulder. The Fiske Planetarium features a 65-foot diameter dome and has undergone significant technological upgrades, making it one of the most advanced planetariums in the country. It offers a variety of shows, including live demonstrations and immersive experiences that simulate different cosmic phenomena and environments (CU Connections).
Safety and sustainability for any facility begins with an understanding of who shall occupy the built environment and how. University settings, with mixed-use phenomenon arising spontaneously and temporarily, often present challenges. Educational communities are a convergent settings for families; day care facilities among them. First principles regarding occupancy classifications for day care facilities appear in Section 308 of the International Building Code, Institutional Group I; linked below:
The ICC Institutional Group I-4 classification includes buildings and structures occupied by more than five persons of any age who received custodial care for fewer than 24 hours per day by persons other than parents or guardian, relatives by blood, marriage or adoption, and in a place other than the home of the person cared far. This group includes both adult and child day care.
We maintain focus on child day care. Many educational communities operate child day care enterprises for both academic study and/or as auxiliary (university employee benefit) enterprises.

Each of the International Code Council code development groups fetch back to a shared understanding of the nature of the facility; character of its occupants and prospective usage patterns.
The 2024 revision of the International Building code is in production now. Ahead of the formal, market release of the Group A tranche of titles you can sample the safety concepts in play during this revision with an examination of the documents linked below:
Search on the terms “day care” and “daycare” in the link at the top of this page to get a sample of the prevailing concepts; use of such facilities as storm shelters, for example.

We encourage our safety and sustainability colleagues to participate directly in the ICC Code Development process. We slice horizontally through the disciplinary silos (“incumbent verticals”) created by hundreds of consensus product developers every week and we can say, upon considerable authority that the ICC consensus product development environment is one of the best in the world. Privately developed standards (for use by public agencies) is a far better way to discover and promulgate leading practice than originating technical specifics from legislative bodies. CLICK HERE to get started. Contact Kimberly Paarlberg (kpaarlberg@iccsafe.org) for more information.
There are competitor consensus products in this space — Chapter 18 Day-Care Occupancies in NFPA 5000 Building Construction and Safety Code, for example; a title we maintain the standing agenda of our Model Building Code teleconferences. It is developed from a different pool of expertise under a different due process regime. See our CALENDAR for the next online meeting; open to everyone.
