Energy Standard for Sites & Buildings: Metering
Section 8 Key points:
Metering for New Buildings: New buildings larger than 25,000 square feet must be equipped with metering to measure the electrical energy usage of the entire building.
Tenant Spaces: In buildings with tenant spaces, individual tenant spaces larger than 10,000 square feet must also be separately metered.
Subsystem Metering: Buildings with electrical loads exceeding specified thresholds must have additional metering to measure energy use for various subsystems, including:
HVAC systems
Lighting systems
Plug loads
Process loads
These metering requirements are intended to help building owners and operators monitor energy consumption, identify opportunities for energy savings, and comply with building energy codes and standards.
Despite best intentions a fair question to ask: What does over metering look like? (University of Alberta Research)

The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) is an ANSI-accredited continuous-maintenance standards developer (a major contributor to what we call a regulatory product development “stream”). Continuous maintenance means that changes to titles in its catalog can change in as little as 30-45 days. This is meaningful to jurisdictions that require conformance to the “latest” version of ASHRAE 90.1
Among the leading titles in its catalog is ASHRAE 90.1 Energy Standard for Sites and Buildings Except Low-Rise Residential Buildings. Standard 90.1 has been a benchmark for commercial building energy codes in the United States and a key basis for codes and standards around the world for more than 35 years. Free access to ASHRAE 90.1 version is available at the link below:
READ ONLY Version of 2022 ASHRAE 90.1
If you cannot access it with the link above, try the link below and select 90.1 from the title list:
Current Popular ASHRAE Standards and Guidelines
Chapter 9: Lighting, begins on Page 148, and therein lie the tables that are the most widely used metrics (lighting power densities) by electrical and illumination engineers for specifying luminaires and getting them wired and controlled “per code”. Many jurisdictions provide access to this Chapter without charge. Respecting ASHRAE’s copyright, we will not do so here but will use them during today’s Illumination Colloquium, 16:00 UTC.
Keep in mind that recently ASHRAE expanded the scope of 90.1 to include energy usage in the spaces between buildings:
25 January 2023: Newly Released ASHRAE 90.1-2022 Includes Expanded Scope For Building Sites
At this time, there are no redlines open for public comment
Online Standards Actions & Public Review Drafts
Education industry facility managers, energy conservation workgroups, sustainability officers, electric shop foreman, electricians and front-line maintenance professionals who change lighting fixtures, maintain environmental air systems are encouraged to participate directly in the ASHRAE consensus standard development process.

The De-Population Bomb
February 16, 2024: North Shore Medical Center abruptly closes neo-natal, labor and delivery units
United States National Institute of Health Gene Map
“In 1970, Stanford professor Paul Ehrlich published a famous book, The Population Bomb, in which he described a disastrous future for humanity:
‘The battle to feed all of humanity is over. In the 1970s and 1980s hundreds of millions of people will starve to death in spite of any crash programs embarked upon now.’
That prediction turned out to be very wrong, and in this interview American Enterprise Institute scholar Nicholas Eberstadt tells how we are in fact heading toward the opposite problem: not enough people. For decades now, many countries have been unable to sustain a #population replacement birth rate, including in Western Europe, South Korea, Japan, and, most ominously, China. The societal and social impacts of this phenomenon are vast. We discuss those with Eberstadt as well as some strategies to avoid them.”
Out take [35:22]:
“…All right this gets us right to the heart of of your essay and of the matter quoting you yet again the single best predictor for National fertility rates happens to be wanted family size as reported by women now you note there are polls that ask women how many children they’d like and you know that this doesn’t correlate perfectly with birth rates but it’s the best indicator in one sense this is a reassuring even heartening finding it highlights the agency at the very heart of our Humanity…
[“You’re talking about free will there people choosing their family size but if we permit the non-material realm of life to figure into our inquiry we may conclude that proposals to revive the American birth rate through subsidies vastly underestimate the challenge the challenge May ultimately prove to be civilizational in nature”]
okay so I look at first of all that hits like a two by four — civilizational in nature — and on the one hand I think to myself wait a minute aren’t we all supposed to be delighted that in this modern world women are in a position to participate in the workforce they’re in a position to choose more carefully more explicitly more intentionally the number of children they’d like to have aren’t we supposed to believe that that’s a wonderful thing and that releasing that many women to the workforce should increase the dynamism and growth of our [economy]…and all that…good, good, good…”

Lively Arts 300
The term “lively arts” is attributed to American writer and poet James Thurber. It was popularized in the mid-20th century as a way to describe various forms of performing arts, such as theater, dance, music, and other creative expressions.

“What art is, in reality, is this missing link, not the links which exist.
It’s not what you see that is art; art is the gap”
— Marcel Duchamp
Today we refresh our understanding of the literature that guides the safety and sustainability goals of lively art events in educational settlements. Consortia have evolved quickly in recent years, leading and lagging changes in the content creation and delivery domain. With this evolution a professional discipline has emerged that requires training and certification in the electrotechnologies that contribute to “event safety”; among them:
ASHRAE International
Standard 62.1: This standard establishes minimum ventilation rates and indoor air quality requirements for commercial buildings, including theaters and auditoriums.
Standard 55: This standard specifies thermal comfort conditions for occupants in indoor environments, which can have an impact on air quality.

Acoustics
Hearing is one of the most crucial means of survival in the animal world and speech is one of the most distinctive characteristics of human development and culture. Accordingly, the science of acoustics spreads across many facets of human society—music, medicine, architecture, industrial production and more recently in off-site instructional facilities. Join us today at 15:00 UTC when we review the best practice catalogs of the peak standards-setting organizations for titles relevant to education communities.

Solar (Winter)
| Sie strahlt vor Freude über ihre Auszeichnung – TH-Alumna Melanie Klaus. Für ihre Bachelorarbeit im Bereich Erneuerbare Energien wurde sie vom Solarenergieförderverein Bayern geehrt. In ihrer Bachelorarbeit im Studiengang Elektro- und Informationstechnik untersuchte sie das Zusammenspiel von Wind- und Solarenergie und den Nutzen, der sich hieraus für die regenerative Energieerzeugung erzielen lässt. Untersucht wurde also die Nutzung der natürlichen Kombination von Wind und Sonne für die Energieerzeugung. Um die Rentabilität dieser Einspeisekombination zu ermitteln, hat Melanie Klaus ein Software-Tool entwickelt, welches zur Planung und Simulation abgestimmter Photovoltaik-Wind-Kombinationen dient und bereits für die Errichtung einer Photovoltaik-Anlage zu einem Windpark eingesetzt wird. |
