A Procedure to Estimate the Energy Requirements for Lighting
A Procedure to Estimate the Energy Requirements for Lighting

Sapienza, University of Rome
Abstract: The amount of the electrical energy used for the interior lighting of medium and large buildings is generally considerable. The European Standard EN15193 was devised to establish conventions and procedures for the estimation of energy requirements of lighting in buildings by an energy performance numeric indicator. This methodology is based on the three derating factors that consider the influence of the daylight exploitation, the occupancy behavior and, if present, of a constant illuminance sensor. The factors are evaluated by a statistical approach on the basis of general reference data tabulated by the same Standard, not considering more detailed parameters of the control system that can impact severely in the effective energy savings. The Standard methodology appears extremely useful for a preliminary evaluation. For a more accurate evaluation, this paper suggests an improvement of the procedure that considers the effective operation time and occupancy behavior, the type of control and lamps, the number of control groups, the technique of modulation (dimming or switching), and the delay in turning off. The suggested procedure is compared with the Standard one to highlight the improvements.

Duncan Stroik Architect
“The ideal architect should be a man of letters, a skillful draftsman, a mathematician,
familiar with historical studies, a diligent student of philosophy, acquainted with music,
not ignorant of medicine, learned in the responses of jurisconsults,
familiar with astronomy and astronomical calculations.”
Duncan G. Stroik is a practicing architect, author, and Professor of Architecture at the University of Notre Dame specializing in religious and classical architecture. Gathered here are images from Christ Chapel, Hillsdale College Michigan. His award-winning work includes the Our Lady of the Most Holy Trinity Chapel in Santa Paula, California, the Shrine of Our Lady of Guadalupe in LaCrosse, Wisconsin, and the Cathedral of Saint Joseph in Sioux Falls, South Dakota.
A frequent lecturer on sacred architecture and the classical tradition, Stroik authored The Church Building as a Sacred Place: Beauty, Transcendence and the Eternal and is the founding editor of Sacred Architecture Journal. He is a graduate of the University of Virginia and the Yale University School of Architecture. Professor Stroik is the 2016 winner of the Arthur Ross Award for Architecture. In 2019, he was appointed to the U.S. Commission of Fine Arts.

Food Safety
Overdoor, France, ca. 1825; | Smithsonian Design Museum
Education communities have significant food safety responsibilities. Risk gets pushed around global food service counterparties; a drama in itself and one that requires coverage in a separate blog post.*
Since 2013 we have been following the development of food safety standards; among them ANSI/NSF 2: Food Equipment one of a constellation of NSF food safety titles whose provisions cover bakery, cafeteria, kitchen, and pantry units and other food handling and processing equipment such as tables and components, counters, hoods, shelves, and sinks. The purpose of this Standard is to establish minimum food protection and sanitation requirements for the materials, design, fabrication, construction, and performance of food handling and processing equipment.
It is a relatively stable standard; developed to support conformance revenue for products. A new landing page seems to have emerged in recent months:
https://www.nsf.org/testing/food
You may be enlightened by the concepts running through this standard as can be seen on a past, pre-pandemic agenda:
NSF 2 Food Safety 2019 Meeting Packet – Final Draft
NSF 2 Food Safety 2019 Meeting Summary – August 21-22 Ann Arbor NSF Headquarters
NSF 2 Food Equipment Fabrication Agenda – FEF – TG – 2021-01-12
Not trivial agendas with concepts that cut across several disciplines involving product manufacture, installation, operation and maintenance. We find a very strong influence of organizations such as Aramark and Sodexo. More on that in a separate post.

This committee – along with several other joint committees –meets frequently online. If you wish to participate, and receive access to documents that explain the scope and scale of NSF food safety standards, please contact Allan Rose, (734) 827-3817, arose@nsf.org. NSF International welcomes guests/observers to nearly all of its standards-setting technical committees. We expect another online meeting hosted by this committee any day now.
Keep in mind that all NSF International titles are on the standing agenda of our Nourriture (Food) colloquia; open to everyone. See our CALENDAR for the next meeting.
