A Procedure to Estimate the Energy Requirements for Lighting

 

A Procedure to Estimate the Energy Requirements for Lighting

Giuseppe Parise – Luigi Martirano – Luigi Parise

Sapienza, University of Rome

Abstract:  The amount of the electrical energy used for the interior lighting of medium and large buildings is generally considerable. The European Standard EN15193 was devised to establish conventions and procedures for the estimation of energy requirements of lighting in buildings by an energy performance numeric indicator. This methodology is based on the three derating factors that consider the influence of the daylight exploitation, the occupancy behavior and, if present, of a constant illuminance sensor. The factors are evaluated by a statistical approach on the basis of general reference data tabulated by the same Standard, not considering more detailed parameters of the control system that can impact severely in the effective energy savings. The Standard methodology appears extremely useful for a preliminary evaluation. For a more accurate evaluation, this paper suggests an improvement of the procedure that considers the effective operation time and occupancy behavior, the type of control and lamps, the number of control groups, the technique of modulation (dimming or switching), and the delay in turning off. The suggested procedure is compared with the Standard one to highlight the improvements.

Interoperability of Distributed Energy Resources

IEEE Standard for Interconnecting Distributed Resources with Electric Power Systems is effectively the global standard for interconnection of distributed resources with large scale electric power systems.  It provides requirements relevant to the performance, operation, testing, safety, and maintenance of the interconnection.  Apart from the power reliability and sustainability zietgeist we have seen in campus bulk power distribution systems, this title is usually referenced in research projects undertaken in university research enterprises.  The standard is intended to be universally adoptable, technology-neutral, and cover distributed resources as large 10 MVA.  To wit:

IEEE 1547-2018 Standard for Interconnection and Interoperability of Distributed Energy Resources with Associated Electric Power Systems Interfaces: This standard — emerging from IEEE Root Project 1547.3 — 2007 asserts first principles for improved performance for distributed energy resources, connected to the grid. NIST funding aided this standard’s development.   Links to related titles, recently released for public consultation, are listed below:

We collaborate with the IEEE Education & Healthcare Facilities Committee on this an related titles.   This committee’s meetings are held 4 times monthly in European and American time zones.  International Electrical Technical Commission titles are items on the standing agenda; a few representative titles are listed in addition to IEEE titles below:

IEC 62746-10-1:2018 Systems Interface Between Customer Energy Management System and the Power Management System – Part 10-1: Open Automated Demand Response: This standard specifies how to implement a two-way signaling system, between utilities and customers, thus allowing utilities to adjust the grid’s load, based on demand. NIST’s David Holmberg and Steve Bushby presented research to the International Electrotechnical Commission (IEC), aiding this US standard’s acceptance as an international one.

IEC 62746-10-3:2018, Systems Interface Between Customer Energy Management System and the Power Management System – Part 10-3: Open Automated Demand Response – Adapting Smart Grid User Interfaces to the IEC Common Information Model: Related to the previous standard, IEC 62746-10-3:2018 defines the interfaces, as well as, the messaging for this two-way signaling system. NIST’s Holmberg and Bushby also facilitated this international standard’s acceptance.

IEEE 21451-001-2017 Recommended Practice for Signal Treatment Applied to Smart Transducers: This guide supports the ability to uniformly processing and classifying data from sensors and actuators in a smart system. The standard enables a common interpretation of data and grid interoperability. NIST personnel served on this standard’s working group, providing NIST research on sensors and actuators.

IEEE 2030.7-2017 Standard for the Specification of Microgrid Controllers: This standard established requirements for controllers, used to sense and manage microgrids. These requirements inform the manufacturing of controllers, and ultimately enable grid interoperability. NIST funding aided this standard’s development.

IEEE 2030.8 Standard for Testing Microgrid Controllers: This testing standard helps verify that microgrid controllers meet these requirements, and, thus, will work as intended. NIST funding aided this standard’s development.

IEEE 1547-2018 Standard for Interconnection and Interoperability of Distributed Energy Resources with Associated Electric Power Systems Interfaces: This standard ushers in a new era of improved performance for distributed energy resources, connected to the grid. NIST funding aided this standard’s development.

Qualification Standard for Power Plant Operators

EPRI is an independent, nonprofit organization that is primarily funded by its member utilities. These member utilities are typically electric power companies, and they contribute financially to EPRI to support its research and development activities.

While EPRI is not directly funded by the government, it does collaborate with various government agencies on research projects and receives funding for specific initiatives through government grants and contracts. Additionally, some of EPRI’s research and development efforts align with government priorities in areas such as renewable energy, environmental sustainability, and grid modernization.

Electrical inspectors (See NFPA 1078) typically do not have jurisdiction over electrical power plants. Electrical power plants, especially large-scale utility power plants, are subject to much more stringent regulations and oversight than regular electrical installations. The responsibility for inspecting and ensuring the safety and compliance of power plants falls under various government agencies and organizations.

In the United States, for example, power plants are subject to federal regulations set forth by the U.S. Nuclear Regulatory Commission (NRC) for nuclear power plants or the U.S. Environmental Protection Agency (EPA) for fossil fuel power plants. Additionally, state regulatory agencies and utility commissions may have their own specific requirements and oversight for power plants within their jurisdictions.

Power plants typically undergo rigorous inspections and audits to ensure compliance with safety, environmental, and operational standards. These inspections are conducted by specialized teams of engineers, experts, and representatives from relevant regulatory bodies and utilities.

While electrical inspectors may not have jurisdiction over power plants, they play a crucial role in inspecting and ensuring the safety of electrical installations in other settings, such as smaller power generation facilities (i.e. district energy plants) that are not exempted by self-assessment charters granted to many large university power plants.

Abstract. Academic laboratories should be a safe environment in which one can teach, learn, and conduct research. Sharing a common principle, the prevention of potential accidents and imminent injuries is a fundamental goal of laboratory environments. In addition, academic laboratories are attributed the exceptional responsibility to instill in students the culture of the safety, the basis of risk assessment, and of the exemplification of the prudent practice around energized objects.  Undergraduate laboratory assignments may normally be framed based upon the repetition of established experiments and procedures, whereas, academic research laboratories may involve new methodologies and/or apparatus, for which the hazards may not be completely known to the faculty and student researchers. Yet, the academic laboratory should be an environment free of electrical hazards for both routine experiments and research endeavors, and faculty should offer practical inputs and safety-driven insights to academic administration to achieve such a paramount objective. In this paper, the authors discuss the challenges to the electrical safety in modern academic laboratories, where users may be exposed to harmful touch voltages.

VIII. CONCLUSION

Safety is the most important practice in an academic laboratory as “safety and productivity are on the same team”.  Electrical measurement and electrically-powered equipment of various brands and models are common in both teaching and research laboratories, highlighting the need to maintaining them continuously in an electrically-safe status.  Annual reports on the occurrence of electrical hazards (i.e. shocks and injuries) in academic laboratory environments primarily discover the (i) lack of knowledge on using the electrical equipment, (ii) careless use of the energized electric facilities, and (iii) faulty electrical equipment or cords. The above does call for the establishment of safety-driven codes, instructions, and trainings for the academic personnel working with or near such devices for teaching, learning, experiments, and research. This paper provided background information on the concept of electrical safety in the academic laboratories, presented the safety challenges of modern academic laboratories, and offered solutions on how enhance the lab environment and research personnel safety awareness to avoid and control electrical hazards.

Today we break down the literature for building, maintaining and supporting the computing infrastructure of education settlements.  We use the term “infotech” gingerly to explain action for a  broad span of technologies that encompass enterprise servers and software, wireless and wired networks, campus phone networks, and desktop computers that provide administrative services and career tech video production.   The private sector has moved at light speed to respond to the circumstances of the pandemic; so have vertical incumbents evolving their business models to seek conformance revenue.  Starting 2023 we break down the topic accordingly:

Infotech 200:  Wired and wireless infrastructure for education and administration related to teaching sciences and supporting fine and lively arts

Infotech 400:  Physical system middleware for research facilities; data center location, power supply, cooling systems, fire suppression, security, monitoring and management.

The literature radiates continually by consortia, open-source, or ad hoc standards-setting domains rather than the private standards system administered by global and standards setting bodies; to wit:

International:

IEC (EN 50600), IET, ISO, ITU

Freely Available ICT Standards

IEEE

Education & Healthcare Facility Electrotechnology Committee

United States:

ASHRAE

Energy Standard for Data Centers

ATIS

BICSI

Data Center Operations and Maintenance Best Practices

INCITS, NFPA, NIST, TIA (942)

Everywhere else:

3GPP & 3GPP2,  Apache Software Foundation,  ISTE,  OneM2M,  Uptime Institute

The ICT domain is huge, replacing physical libraries.  The foregoing is a highly curated sample.

We continue to include teaching and learning media standards on our colloquia however it is likely that will break up this topic into at least two related colloquia as 2022 proceeds; with primary focus on the design, construction and maintenance of the physical ICT infrastructure.  Much depends upon the interest of our clients, colleagues and other stakeholders.  We collaborate closely with the IEEE Education and Healthcare Electrotechnology Committee.

Today we break form from our normal custom of assessing conceptual movement in stabilized safety and sustainability standards for education settlements and, instead, venture into a domain that will inform nearly everything we do; and with gathering pace.

We begin with the action among the experts in the organizations listed below:

  1. National Institute of Standards and Technology (NIST):
    • NIST’s Post-Quantum Cryptography Standardization: NIST is working on standardizing cryptographic algorithms that are secure against quantum attacks. The goal is to ensure that data remains secure even with the advent of quantum computers. This involves selecting algorithms through an open competition, which began in 2016, and is still ongoing.
    • Quantum Information Program: NIST conducts research and develops standards related to quantum information science, including quantum computing, quantum communication, and quantum metrology.
  2. Quantum Economic Development Consortium (QED-C):
    • Formed as part of the National Quantum Initiative Act, QED-C aims to enable and grow the quantum industry in the U.S. It involves various stakeholders, including industry, academic institutions, and government agencies, working together to identify and address standards and other needs to foster a robust quantum ecosystem.
  3. National Quantum Initiative (NQI):
    • Established by the National Quantum Initiative Act in 2018, NQI coordinates efforts across multiple agencies, including NIST, the Department of Energy (DOE), and the National Science Foundation (NSF), to advance quantum information science. This includes the development of standards, infrastructure, and research to support quantum technologies.
  4. International Standards:
    • While primarily international, organizations like the International Telecommunication Union (ITU) and the International Organization for Standardization (ISO) have working groups focusing on quantum technologies. U.S. participation in these groups helps ensure that global standards align with U.S. interests and priorities.
  5. Federal Agencies and Research Programs:
    • The DOE, NSF, and other federal agencies fund research and development in quantum computing, which often includes aspects related to standards and best practices. For example, the DOE’s Quantum Information Science (QIS) Research Centers and NSF’s Quantum Leap Challenge Institutes.
  6. Industry-Led Initiatives:
    • Several industry consortia and companies are actively involved in developing quantum computing standards. Organizations like the IEEE have working groups focused on quantum computing and quantum communications standards.

Overall, the U.S. approach to quantum computing standards is multifaceted, involving federal agencies, industry consortia, academic research, and participation in international standard-setting bodies.
