Illumination 400

IEEE Education & Healthcare Facilities Committee

NEC Section 226.6 Conductor Size and Support (B) Festoon Lighting

EC&M Article 225: Outside Branch Circuits

Electrical Time: Definition of Festoon Lighting

“Starry Night Over the Rhône” 1888 Vincent van Gogh


Today we refresh our understanding of the moment in illumination technologies for outdoor lighting systems— related but different from our exploration of building interior illumination systems in Illumination 200.  Later in 2024 we will roll out Illumination 400 (Holiday illumination) and Illumination 500 which explores litigation related to public illumination technology.  As cities-within-cities the shared perimeter of a campus with the host municipality has proven rich in legal controversy and action.

Illumination technology was the original inspiration for the electric utility industry; providing night-time security and transforming every sector of every economy on earth.  Lighting load remains the largest component of any building’s electric load — about 35 percent– making it a large target for energy regulations.

Our inquiry begins with selections from the following documents…

International Electrotechnical Commission TC 34 Lighting

IEC 60364 Electrical Installations in Buildings

2023 National Electrical Safety Code

IEEE P3001.9 – Recommended Practice for the Design of Power Systems Supplying Lighting Systems in Commercial and Industrial Facilities

Institution of Engineering and Technology: Recommendations for Energy-efficient Exterior Lighting Systems

2023 National Electrical Code: Article 410  (While the bulk of the NEC concerns indoor wiring fire hazards, there are passages that inform outdoor lighting wiring safety)

2019 ASHRAE 90.1: Chapter 9 Lighting

Illumination Engineering Society: Various titles

ISO/TC 274 Light and lighting

Salt Water River Project: Outdoor Lighting Standards

US DOE-EERE Building Energy Codes Program

…and about 20 other accredited, consortia or ad hoc standards developers and publishers aligned principally with vertical incumbents.  Illumination was the original inspiration (i.e. the first “killer app”) for the electrical power industry in every nation.  Its best practice literature reflects a fast-moving, shape-changing domain.

Outdoor lighting systems can be owned and maintained by different entities depending on the context and location. Here are some examples of ownership regimes for outdoor lighting systems:

  1. Public ownership: In this case, outdoor lighting systems are owned and maintained by the local government or municipal authority. The lighting may be installed in public spaces such as parks, streets, and other outdoor areas for the safety and convenience of the public.
  2. Private ownership: Outdoor lighting systems may be owned by private individuals or organizations. For example, a business owner may install outdoor lighting for security or aesthetic reasons, or a homeowner may install outdoor lighting in their garden or yard.
  3. Co-owned: Outdoor lighting systems may be owned jointly by multiple entities. For example, a residential community may jointly own and maintain outdoor lighting in their shared spaces such as parking areas, community parks, or recreational facilities.
  4. Utility ownership: Outdoor lighting systems may be owned and maintained by utility companies such as electric or energy companies. These companies may install and maintain street lights or other lighting systems for the public good.
  5. Third-party ownership: In some cases, a third-party entity may own and maintain outdoor lighting systems on behalf of a public or private entity. For example, a lighting contractor may install and maintain lighting in a public park on behalf of a local government.

The ownership regime of an outdoor lighting system can have implications for issues such as installation, maintenance, and cost-sharing. It is important to consider ownership when designing and implementing outdoor lighting systems to ensure their long-term effectiveness and sustainability.

Global Positioning System: A Generation of Service to the World

Citizens of the Earth depend upon United States leadership in this technology for several reasons:

Development: The GPS was originally developed by the US Department of Defense for military purposes, but it was later made available for civilian use. The US has invested heavily in the development and maintenance of the system, which has contributed to its leadership in this area.

Coverage: The GPS provides global coverage, with 24 satellites orbiting the earth and transmitting signals that can be received by GPS receivers anywhere in the world. This level of coverage is unmatched by any other global navigation system.

Accuracy: The US has worked to continually improve the accuracy of the GPS, with current accuracy levels estimated at around 10 meters for civilian users and even higher accuracy for military users.

Innovation: The US has continued to innovate and expand the capabilities of the GPS over time, with newer versions of the system including features such as higher accuracy, improved anti-jamming capabilities, and the ability to operate in more challenging environments such as indoors or in urban canyons.

Collaboration: The US has collaborated with other countries to expand the reach and capabilities of the GPS, such as through the development of compatible navigation systems like the European Union’s Galileo system and Japan’s QZSS system.

United States leadership in the GPS has been driven by a combination of investment, innovation, collaboration, and a commitment to improving the accuracy and capabilities of the system over time.

What Is A Standard Drink?

 

“Rather a bottle in front of me than a frontal lobotomy”

— Some guy

 

Many people are surprised to learn what counts as a “drink”. The amount of liquid in your glass, can, or bottle does not necessarily match up to how much alcohol is actually in your drink.  Even before the United States federal government withdrew from regulating alcohol, the conversation, and degree of agreement and  attitude, remains remarkably regionally specific:

Kitchens 300

United States Air Force Military Academy

Commercial kitchens in school cafeterias and college dormitories are designed to meet strict health and safety standards, accommodate high-volume food production, and provide nutritious meals to students in an efficient and organized manner.  Some common features:

  • Industrial-grade cooking equipment: This may include commercial ovens, grills, ranges, fryers, steamers, and other specialized cooking equipment designed for high-volume cooking.
  • Food preparation areas: These may include spacious prep tables, cutting boards, sinks, and other food preparation stations for washing, chopping, and assembling ingredients.
  • Walk-in refrigerators and freezers: These are used for storing large quantities of perishable food items at appropriate temperatures to maintain freshness and safety.
  • Food storage facilities: These may include shelves, racks, and cabinets for storing dry goods, canned goods, and other non-perishable food items.
  • Dishwashing area: This may include commercial dishwashers capable of handling a large number of dishes and utensils efficiently.
  • Serving stations: These may include counters, warming stations, and other facilities for serving food to students.
  • Ventilation and exhaust systems: These are essential for maintaining a clean and safe kitchen environment by properly removing smoke, steam, and odors generated during cooking.
  • Safety features: These may include fire suppression systems, emergency exits, and other safety measures to ensure compliance with local health and safety regulations.

Owing to the complexity of the domain, starting 2023 we will break down the standards for education community safety and sustainability into two separate colloquia:

Kitchens 100 will deal primarily safety — fire, shock hazard, sanitation, floors, etc.

Kitchens 300 will deal with sustainability criteria in large commercial kitchens common in school cafeterias, dormitories, sports venues and hospitals.

Charcuterie

Charcuterie refers to a variety of cured meats, often accompanied by an assortment of cheeses, fruits, nuts, bread, and spreads. Originating from France, charcuterie was initially focused solely on prepared meat products, such as sausages, pâtés, and confits. Today, a charcuterie board is a popular way to serve an array of meats and complementary foods in a visually appealing and flavorful arrangement as demonstrated here for the Office of Alumni and Family Engagement by Alaura Westrol, Class of 2011.

“How to Escape the Woke Matrix”

“Wokeism” is a term that has been used to describe a cultural and political movement characterized by a heightened awareness of social and political issues related to race, gender, and various forms of discrimination and inequality. The term is often used in a pejorative or critical manner by those who view it as excessive or overly focused on identity politics.

The concept of being “woke” originally comes from African American Vernacular English and referred to being socially and politically aware, especially in the context of racial injustice and inequality. It has since evolved into a broader movement that advocates for social justice and equality across various marginalized groups, including racial, gender, sexual, and socioeconomic minorities.

Supporters of wokeism argue that it is important to address systemic discrimination and promote inclusivity and equity in society. Critics, on the other hand, may use the term “wokeism” to criticize what they see as an excessive or dogmatic approach to social justice issues, often accusing it of being overly politically correct or censorious of dissenting opinions.  —  (ChatGPT)
