“Electrical Building World’s Columbian Exposition Chicago 1892

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.

Comment on FERC Action

The Federal Energy Regulatory Commission is an independent agency within the U.S. federal government that regulates interstate transmission of electricity, natural gas, and oil. It oversees wholesale energy markets, pipeline infrastructure, and hydroelectric projects, ensuring fair rates and reliability. While independent, FERC operates under the Department of Energy’s umbrella but does not take direct orders from the executive branch.

FERC enforces energy laws, approves infrastructure projects, and regulates market competition. FERC plays a crucial role in balancing economic, environmental, and energy security concerns, aiming to maintain a stable and efficient energy system across the United States.  Since the U.S. shares interconnected electricity grids with Canada and Mexico, FERC’s decisions on transmission rules and pricing affect energy flows and grid reliability in both countries.

Our interest lies in closing a technical gap that exists upstream from the building service point and downstream from the utility supply point. Some, not all of it, can be accomplished with titles in the IEEE catalog.

Given the dominance of vertical incumbents in the electric power domain, we have submitted a tranche of reliability concepts into the ASHRAE, NFPA and ICC catalogs — not so much with the expectation that they will be gratefully received — but that our proposals will unleash competitive energies among developers of voluntary consensus standards.

One of our proposals will be heard at the April-May meetings of the International Code Council.

Readings / The Administrative State

In power system engineering, availability and reliability are two important concepts, but they refer to different aspects of the system’s performance.

Reliability:

  • Reliability refers to the ability of a power system to perform its intended function without failure for a specified period under given operating conditions. It is essentially a measure of how dependable the system is.
  • Reliability metrics often include indices such as the frequency and duration of outages, failure rates, mean time between failures (MTBF), and similar measures.
  • Reliability analysis focuses on identifying potential failure modes, predicting failure probabilities, and implementing measures to mitigate risks and improve system resilience.Availability:
  • Availability, on the other hand, refers to the proportion of time that a power system is operational and able to deliver power when needed, considering both scheduled and unscheduled downtime.
  • Availability is influenced by factors such as maintenance schedules, repair times, and system design redundancies.
  • Availability is typically expressed as a percentage and can be calculated using the ratio of the uptime to the total time (uptime plus downtime).
  • Availability analysis aims to maximize the operational readiness of the system by minimizing downtime and optimizing maintenance strategies.

Reliability focuses on the likelihood of failure and the ability of the system to sustain operations over time, while availability concerns the actual uptime and downtime of the system, reflecting its readiness to deliver power when required. Both concepts are crucial for assessing and improving the performance of power systems, but they address different aspects of system behavior.

 UPDATED POLICIES ON U.S. DECARBONIZATION AND TECHNOLOGY TRANSITIONS


June 15:FERC Finalizes Plans to Boost Grid Reliability in Extreme Weather Conditions

On Monday June 13th, Federal Energy Regulatory Commission commissioners informed the House Committee on Energy and Commerce that the “environmental justice” agenda prohibits reliable dispatchable electric power needed for national power security. One megawatt of natural gas generation does not equal one megawatt of renewable generation. The minority party on the committee — the oldest standing legislative committee in the House of Representatives (established 1795) — appears indifferent to the reliability consequences of its policy.

Joint Federal-State Task Force on Electric Transmission

“Our nation’s continued energy transition requires the efficient development of new transmission infrastructure. Federal and state regulators must address numerous transmission-related issues, including how to plan and pay for new transmission infrastructure and how to navigate shared federal-state regulatory authority and processes. As a result, the time is ripe for greater federal-state coordination and cooperation.”

Sporty weather season in the United States inspires a revisit of best practice for designing, building and maintaining the systems that provide limited electricity when the primary source fails. We have been active in the development of this and related titles for decades and have presented several proposals to the technical committee. Public input for the 2028 Revision will be received until June 4, 2025.
