Pathways 100

Today we break down the literature for exterior and interior pathways in education communities. We limit the term “pathway” to refer to human pathways (as in egress and ingress paths); not wiring or piping pathways. Maximum distance of travel from within a building and along an egress path toward safety is a core topic in building safety literature. Starting 2023 we will break down coverage of subject catalogs and bibliographies:

Pathways 100: Survey of all titles for both the exterior and interior environments

Pathways 200: Review of codes, standards and guidelines for building interiors

Related recent research:

Hallways and stairways lighting system cost reduction

The research on circadian rhythm parameters testing of lighting quality in classrooms

Research and discussion on classroom blackboard lighting

Pathways 300: Review of codes, standards and guidelines campus environment outside the buildings; all seasons

Pathways 500: Review of noteworthy litigation. Campus pathways are rich in possibilities for legal actions so we will refresh our understanding of the landmark decisions.

This breakdown is “somewhat” inspired by recent action by ASHRAE International to expand the scope of ASHRAE 90.1 to heating and cooling environments outside buildings. The new title of ASHRAE 901. includes the word “Site”, which is another way of saying “the world” outside buildings. Standards Michigan commented on the consequences of doing this in the proposal stages in 2020-2021.

The topic involves titles from many standards setting organizations; among them:

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:

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.
