Illumination 100

Replacing oil and natural gas lighting, the first practical electric light bulb was invented by Thomas Edison in 1879.  Joseph W. Swan filed a similar Electric Lamp Patent in 1880.  One of the first large-scale installations of electric lighting was at the Savoy Theatre in London in 1881, which was followed by the installation of electric lights in the Palace of Westminster in 1882. By the 1890s, electric lighting had become more widespread and affordable.

The widespread transition to LED lighting in buildings began in the early 2010s. While LED technology had been available since the 1960s, it wasn’t until the 2000s that the technology improved to the point where LED lighting was cost-effective and efficient enough to replace traditional lighting technologies like incandescent and fluorescent lighting.  In addition to their energy efficiency, LED lights also have a longer lifespan than traditional lighting technologies, which makes them more cost-effective over the long term.

What is light?

Today we refresh our understanding of the moment in illumination technologies.  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.  We are organizing our approach to this topic during 2023:

Illumination 100.  Survey of illumination standards catalogs

Illumination 200.  Interior illumination including industrial and laboratory occupancies

Illumination 300.  Exterior illumination with emphasis on pathways

Illumination 400.  Sport lighting, interior and exterior

Illumination 500.  Advanced topics including relevant legislation and litigation.

Except jankiness for most of 2023.  We have been doing this work since 1993 — starting with the National Electrical Code — and getting the topic organized into manageable segments will be a challenge.

Today our inquiry begins with selections from the following documents:

International Electrotechnical Commission TC 34 Lighting

IEC 60364 Electrical Installations in Buildings

Electrical installations and Protection Against Electric Shock

2023 National Electrical Safety Code

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

2023 National Electrical Code: Article 410

2019 ASHRAE 90.1: Chapter 9 Lighting

Illumination Engineering Society: Various titles

ISO/TC 274 Light and lighting

…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.

Best practice for campus outdoor lighting system wiring is asserted in the 2023 National Electrical Code primarily in Articles 225 (Outside Branch Circuits and Feeders) and Article 41 (Luminaires, Lampholders, and Lamps).

We have done a fair amount of work on this topic over the years, including writing the chapter on campus outdoor lighting for the soon-to-be-released IEEE 3001.9 Recommended Practice for the Design of Power Systems Supplying Lighting Systems in Commercial and Industrial Facilities.

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

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.

Law on the State of Emergency

 

“A smooth sea never made a skilled sailor.”
— Franklin D. Roosevelt

 

University of Melbourne Estate Plan


The criteria and process for declaring a state of emergency can vary depending on the country and its legal framework. However, governments generally consider certain factors and criteria when making such declarations. Here are some common elements that governments use to determine whether to declare a state of emergency:

  1. Imminent Threat: Governments typically declare a state of emergency when there is an imminent threat to public safety or the normal functioning of society. This could include natural disasters (such as hurricanes, earthquakes, or floods), severe public health emergencies (like pandemics), acts of terrorism, civil unrest, or other situations that pose a significant risk.
  2. Scale and Severity: The scale and severity of the situation play a crucial role in declaring a state of emergency. Governments assess whether the event or circumstances are beyond the capacity of regular governmental and emergency response systems to effectively manage and mitigate the impact.
  3. Public Safety and Welfare: Governments consider the potential impact on public safety, welfare, and infrastructure. If the situation poses a substantial risk to lives, property, critical infrastructure, or essential services, it may warrant a declaration of a state of emergency.
  4. Legal Framework: Countries typically have legal frameworks in place that outline the conditions and procedures for declaring a state of emergency. Governments assess whether the situation meets the legal requirements and conditions specified in these frameworks.
  5. Proportionality: The principle of proportionality is often considered, ensuring that the measures taken during the state of emergency are proportional to the threat or situation at hand. Governments aim to strike a balance between protecting public safety and minimizing unnecessary disruption to individual rights and liberties.
  6. Expert Advice and Recommendations: Governments rely on expert advice and recommendations from relevant authorities, such as emergency management agencies, health organizations, and security agencies, to assess the situation and determine the need for a state of emergency.

It’s important to note that the specific criteria and procedures for declaring a state of emergency can vary significantly between countries. The legal provisions and powers granted to the government during a state of emergency also vary, including the duration, scope of authority, and measures that can be implemented. It’s advisable to consult the specific laws and regulations of the country in question to understand the precise criteria and process involved in declaring a state of emergency.

Infotech 300

“The more abundant the information in the world,

the more economics becomes the science of allocating attention.”

— George Gilder

Today we break down the literature for building, maintaining and supporting the computing infrastructure of education communities.  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 in this plasma-hot domain.

Starting 2023 we break down the topic accordingly:

Infotech 100: Survey of the principal standards developing organizations whose catalogs are incorporated by reference into federal and state legislation.  Revision cycles.

Infotech 200: Campus computing facilities for research and education

Infotech 300: Communication networks, wired and unwired at the demarcation point; crucial for defining the responsibilities and boundaries between the service provider and the customer.

Infotech 400:  System, middleware and application for education and research


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

Vocabulary

Freely Available ICT Standards

IEEE Communications Society

United States:

ASHRAE,

Energy Standard for Data Centers

ATIS


BICSI

Information and Communication Technology Systems Design and Implementation Best Practices for Educational Institutions and Facilities

Information Communication Technology Systems Design and Implementation Best Practices for Healthcare Institutions and Facilities

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 2023 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.
