Abstract: Improperly lit architectural heritage sites contribute to intrusive light, impacting the environment. To combat this, a methodology using specialized luminaires with silhouette-based aperture was implemented during the renovation of Slovenian churches. By precisely directing light and minimizing spillage, this approach significantly reduced intrusive light. Real-life example of the Church of St. Thomas exemplifies its success. Such sustainable strategies ensure the preservation of cultural heritage while minimizing environmental impact.
“Starry Night Over the Rhône” 1888 Vincent van Gogh
I often think that the night is more alive
and more richly colored than the day.
– Vincent van Gogh
The International Commission on Illumination — is devoted to worldwide cooperation and the exchange of information on all matters relating to the science and art of light and lighting, colour and vision, photobiology and image technology. The landing page for its standards setting enterprise is linked below:
With strong technical, scientific and cultural foundations, the CIE is an independent, non-profit organization that serves member countries on a voluntary basis. Since its inception in 1913, the CIE has become a professional organization and has been accepted as representing the best authority on the subject and as such is recognized by ISO as an international standardization body.
Illumination technologies influence designs in architectural design, public safety and energy economics in all education communities. We find CIE titles referenced in ISO and IEC standards. Because ISO and IEC standards are incorporated by referenced in the best practice literature published by standards setting organizations in every nation with a private standards setting body (such as ANSI, BSI, DIN, etc.) the CIE titles are worthy of our attention.
There are others that we may track in the fullness of time. Getting illumination technology right is subtle art. The energy to drive normal, steady-state illumination usually consumes 25 to 40 percent of building energy but application of the art — which includes control — can reduce that.
We maintain CIE titles on our periodic Energy, Global, Interiors and Illumination colloquia. See our CALENDAR for the next online meeting; open to everyone.

Today we review the literature informing the safety and sustainability agenda of sport enterprises in education communities; in the United States at least — one of the last, if not the last, meritocracies in academia at large. School districts have hundreds of playgrounds, gymnasiums and playgrounds. Athletic departments are very visible enterprises; particularly at large colleges and universities with varsity teams that have long been “farm clubs” for professional sport companies.
This facility class is far more complicated (technically) than classroom facilities; closer to research and healthcare delivery enterprises in risk aggregation when you consider how many people are involved as spectators. This facility class resides proximate to the actuality of rehabilitated or additional sanitary facilities which we cover in our periodic Water 200 colloquia.
Throughout 2024 we will break down our coverage thus:
We will also explore best practice codes and standards for recreational activity:
Rock Climbing: In the sport of rock climbing, technical skills, grip strength, and body positioning are crucial for both indoor and outdoor climbing. Climbers must navigate a variety of challenging terrains and routes.
Fencing: Fencing requires quick thinking, precise footwork, and precise blade work. Fencers need to anticipate their opponent’s moves and respond with well-timed and accurate attacks and parries.
Quidditch: Once a fictional sport; now widely played as “Quadball”.
There are no fewer than 25 ANSI-accredited standards-setting organizations with a catalog of titles in this domain. We expanded the detail to some of the titles to enlighten understanding the complexity of these spaces:
§ Section 302 Occupancy Classification and Use Designation
§ Section 303 Assembly Group A
§ Section 305 Educational Group E
International Energy Conservation Code
Class IV facilities consisting of elementary school and recreational facilities; and amateur league and high school facilities without provisions for spectators
* Eugen Rosenstock-Huessy (1888-1973) was a German-American philosopher, social thinker, and linguist. He was born in Berlin, Germany, and was raised in a Jewish family. Rosenstock-Huessy studied law, theology, and philosophy in Berlin, but his studies were interrupted by World War I. During the war, he served as a lieutenant in the German army and was taken prisoner by the Russian army.
After the war, Rosenstock-Huessy continued his studies and became a professor of law and sociology at the University of Breslau. He was forced to leave Germany in 1933 because of his opposition to the Nazi regime, and he emigrated to the United States. In the United States, Rosenstock-Huessy continued his academic work and became a professor of social philosophy at Dartmouth College in New Hampshire.
Rosenstock-Huessy’s work focused on the role of language in shaping human culture and social institutions. He believed that language was not just a means of communication but was also a way of creating and organizing social relations. His ideas had a significant influence on the development of linguistic phenomenology and hermeneutics.
Some of his notable works include “Out of Revolution: Autobiography of Western Man”, “Speech and Reality”, and “The Christian Future, or the Modern Mind Outrun”.
Centrifugal paper cleaners are used in the pulp and paper industry to remove unwanted contaminants from pulp or paper stock. These contaminants can include dirt, sand, shives, small fibers, and other impurities that can affect the quality of the final paper product. Centrifugal cleaners work on the principle of centrifugal force and are typically installed in the stock preparation stage of papermaking processes. Here’s how they work:
Inlet: The pulp or paper stock containing contaminants is fed into the centrifugal cleaner through an inlet. The inlet is designed to create a tangential flow of the stock, which imparts a swirling motion to the mixture.
Centrifugal Force: Once inside the cleaner, the stock and contaminants are subjected to centrifugal force due to the rapid rotation of the cleaner’s inner drum or rotor. The centrifugal force causes the heavier contaminants to move toward the outer wall of the cleaner, while the cleaner stock moves toward the center of the drum.
Separation: The contaminants, being heavier, are forced against the outer wall of the cleaner by the centrifugal force, and they accumulate there. The clean stock, which is lighter and free of contaminants, moves toward the center of the cleaner.
Outlet: The cleaned stock exits the cleaner through the center outlet, while the accumulated contaminants are removed from the outer wall. The contaminants can be periodically purged from the cleaner to maintain its efficiency.
Adjustment: Centrifugal cleaners often have adjustable settings to control the separation efficiency. Operators can vary the cleaner’s operating parameters, such as the feed rate, drum speed, and cone angle, to optimize the separation process for different types of contaminants and pulp or paper stocks.
They can operate continuously and provide high efficiency in removing heavy contaminants such as coffee filters. They are often used in conjunction with other cleaning processes, such as screening and flotation, to achieve the desired quality and cleanliness of the pulp or paper stock before it is used in the papermaking process.

We have been following an international conversation on the safe and effective application of reconditioned electrical equipment (RCEE) for the better part of ten years now. Threads of the conversation originating in consensus documents developed by the International Electrotechnical Commission, the CSA Group, the National Association of Electrical Equipment and Medical Imaging Manufacturers (NEMA) and others. The safe and practical application of reconditioned electrical equipment — though not necessarily economical — is debated in detail in the National Electrical Code (NEC); a document in which we have advocated for the education facilities industry since 1993.
Not all electrical equipment is suitable for reconditioning but enough of it can such that specification of RCEE significantly lowers #TotalCostofOwnership for the $300 billion education facilities industry in the United States; the primary goal of Standards Michigan and its 50-state affiliates. According to the National Electrical Manufacturers Association, the following RCEE is suitable:
Industrial and commercial panel boards
Low and medium voltage power circuit breakers
Low and medium voltage replaceable link fuses
Low voltage switchgear
Manual and magnetic controllers
Medium voltage switchgear
Metallic conduit, tubing, raceways and fittings
Motor control centers
Motors
Switchboards
Uninterruptible Power Supply Equipment
The length of this list is a topic upon which good minds disagree; especially internationally. Whether or not the largest non-residential building construction market in the United States (with new construction running at a clip of $80 billion annually) takes advantage of developments in technology that help manufacturers effectively “re-cycle” the largest components of a building power chain is a discussion for another day. The IEEE Education & Healthcare Facilities Committee drills down into details of this nature and is now soliciting comment on the proposed actions of IEEE SCC-18; the IEEE committee which, by charter, is aligned with user-interests in the US standards system. As we explain in our ABOUT, the general public — and even many industry insiders — are not aware of the economic consequences to all industries when regulatory products are written only by incumbent interests.
Suffice to say that even if the US education facilities industry does not apply RCEE to reduce the cost of a new building (by about 1 percent) its competitors internationally will and are.
The 2020 NEC is nearing the completion of its revision cycle. A milestone was completed in early November when all of the 20-0dd technical committees in San Diego. Dozens of breakout task groups are forming to sort through public response to proposed changes to the 2017 NEC which will become the 2020 NEC this time next year. Proposals regarding RCEE landed on the agenda of nearly all 20-odd NEC technical committees. Standards Michigan has tenure in Code Making Panel 1, the committee with oversight about how all other technical committees determine the safe and practical application of RCEE.
Cutting to the chase then, linked below is the first of several transcripts that track CMP-1 debate:
Admittedly, very technical stuff. Few will pay attention to these specifics until something bad happens (perhaps six years from now) so, to avoid something bad happening, we pay attention to it now. We always collaborate with IEEE JTC/PES/IAS and IEEE E&H Committee which meets online twice every month.

We are observers in the development of a new ANSI accredited electronic equipment recycling standard produced with the leadership of NSF International; a Michigan-based standards developer (founded at the University of Michigan) not far from our own offices and one of the largest in the world.
The electronic recycling space is growing quickly — reaching far upstream the value chain into how electronic equipment is designed in the first place. An overview of the project is available in the link below:
This standard moved swiftly to market under NSF International’s continuous maintenance process. We bring it to the attention of the education facilities industry as a recommendation for lowering #TotalCostofOwnership. Participation as a User interest in American national standards development reduces “wheel reinvention” in which many recycling workgroups unnecessarily start from scratch, eliminates the need to attend costly workshops hosted by trade associations and significantly minimizes destructive competition.
This title is on the standing agenda of our Redivivus colloquium. Since our interest lies primarily with electrotechnology we collaborate with the IEEE Standards Association. See our CALENDAR for the next online meeting; open to everyone.

The release of Beaujolais Nouveau is not just about the wine itself; it’s a cultural and marketing phenomenon that brings people together to celebrate the harvest season, promotes the wine industry, and contributes to the economic and cultural vitality of the regions involved. The settlements listed below contribute significantly to wine-related research, education, and innovation. Some notable universities and research institutions in France that lead wine research include:
University of Bordeaux (Institute of Vine and Wine Science): The University of Bordeaux, located in one of the world’s most famous wine regions, is renowned for its research in viticulture, oenology, and wine-related sciences. The Institute of Vine and Wine Sciences (ISVV) within the university is a key research center in this field.
Montpellier SupAgro: Montpellier SupAgro, part of the Montpellier University of Excellence, is known for its expertise in agronomy, viticulture, and oenology. They offer research programs and collaborate with the wine industry.
University of Burgundy: The University of Burgundy, situated in the heart of the Burgundy wine region, conducts research in oenology and viticulture. The Jules Guyot Institute is a leading research facility in the field.
Institut des Sciences de la Vigne et du Vin (ISVV): Located in Bordeaux, this research institute is dedicated to vine and wine sciences and is affiliated with the University of Bordeaux.
University of Reims Champagne-Ardenne: This university, located in the Champagne region of France, has expertise in Champagne production and conducts research related to winemaking and viticulture.
These institutions, along with various research centers and organizations throughout France, contribute to advancements in wine research, including topics like grape cultivation, wine production techniques, wine chemistry, and the study of wine regions and terroirs. They often collaborate with the wine industry and help maintain France’s position as a leader in the global wine industry.
Beaujolais Nouveau is produced under specific regulations and standards set by the French wine industry. However, there isn’t a specific international standard for Beaujolais Nouveau like there is for some other wines, such as those with controlled designations of origin (AOC) or protected designation of origin (PDO) status.
The production of Beaujolais Nouveau is governed by the rules and regulations of the Beaujolais AOC (Appellation d’Origine Contrôlée), which defines the geographical area where the grapes must be grown, the grape varieties allowed, and the winemaking techniques that can be used. The AOC regulations ensure a certain level of quality and authenticity for wines carrying the Beaujolais Nouveau label.
Winemakers producing Beaujolais Nouveau must follow these guidelines, including using the Gamay grape variety, employing specific vinification methods (such as carbonic maceration), and releasing the wine within a limited time frame after the harvest.
While the production standards are regulated at the national level in France, individual producers may have their own techniques and styles within the broader framework of the Beaujolais AOC regulations.
It’s important to note that the term “Beaujolais Nouveau” itself is not a specific indication of quality or adherence to particular winemaking practices; rather, it signifies a style of wine that is young, fresh, and meant to be consumed shortly after production. As a result, the characteristics of Beaujolais Nouveau can vary from producer to producer within the general guidelines set by the AOC
