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:

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.

“No work of art can be great,

if it is not composed of the smallest things.”

— Vitruvius  (Book VII, Chapter 9)

 

Today during our usual hour we sweep through standards action in building glazing, entrances and means of egress.  The word fenestration (Latin: fenestra) has become a term of art for the design, construction, and placement of openings in a building, including windows, doors, skylights, and other glazed elements.  While the word has sparse use in the International Code Council and National Fire Protection Association catalog it is widely used by the Construction Specifications Institute in its MasterFormat system for organizing construction standards, guidelines and building contracts.

The percentage of a building envelope “skin” that is comprised of doors and windows varies depending on the specific building design, function, and location. However, a commonly cited range is between 15% to 25% of the total building envelope.  The actual percentage will depend on several factors such as the building’s purpose, orientation, local climate, and energy performance goals. Buildings that require more natural light or ventilation, such as schools, hospitals, and offices, may have a higher percentage of windows and doors in their envelope. In contrast, buildings with lower lighting and ventilation requirements, such as warehouses, may have a smaller percentage of windows and doors.

Fenestration presents elevated risk to facility managers.  The education facility industry is a large target and a pattern of settling out of court.   For example:

  • In 2013, a former student at Yale University sued the school over a broken window in her dorm room. The student alleged that the university was negligent in failing to repair the window, which allowed a burglar to enter her room and sexually assault her. The case was settled out of court in 2015 for an undisclosed amount.
  • In 2019, a student at the University of California, Los Angeles sued the school over a broken window in her apartment. The student alleged that the university was negligent in failing to repair the window, which allowed a swarm of bees to enter her apartment and sting her. The case was settled out of court for $4.5 million.
  • In 2020, a group of students at Harvard University sued the school over its decision to require them to move out of their dorms due to the COVID-19 pandemic. The students alleged that the university breached its contract with them by failing to provide suitable alternative housing, including functioning windows and doors.  (The case is ongoing; best we can tell as of the date of this post).

These cases illustrate that colleges and universities can face legal action related to doors and windows, either due to alleged negligence in maintaining or repairing them, or due to issues related to student housing and accommodations.

Our inquiry breaks down into two modules at the moment:

Exterior facing fenestration

Interior window walls and doors

Towering Tribute: New Engineering Building Named for Oil Pioneer Autry C. Stephens

North façade: a curtain-wall system uses a custom frit pattern. Architecturally, the frit makes the glass read as more solid and relates its pattern and limestone-like coloration to the adjacent building. Functionally, CO says explicitly that the frit reduces solar heat gain.

East façade: instead of relying entirely on the glazing, the designers introduced angled vertical aluminum fins to respond to the harsh morning sun. The fins also echo the curved geometry of the terra-cotta elsewhere on the building. That’s a particularly nice example of an external architectural element simultaneously becoming a passive solar-control device.

South façade: interestingly, CO uses masonry itself to establish some of the visual rhythm normally supplied by curtain wall. The brick gradually racks outward and eastward, creating changing shadows through the day; its proportions and shadow lines intentionally mimic those of the north curtain wall.

George H.W. Bush 1991 University of Michigan Commencement Speech on “Political Correctness”

“Ironically, on the 200th anniversary of our Bill of Rights, we find free speech under assault throughout the United States, including on some college campuses. The notion of political correctness has ignited controversy across the land. And although the movement arises from the laudable desire to sweep away the debris of racism and sexism and hatred, it replaces old prejudice with new ones. It declares certain topics off-limits, certain expression off-limits, even certain gestures off-limits.”

Abstract:  Indoor signage plays an essential component to find destination for blind and visually impaired people. In this paper, we propose an indoor signage and doors detection system in order to help blind and partially sighted persons accessing unfamiliar indoor environments. Our indoor signage and doors recognizer is builded based on deep learning algorithms. We developed an indoor signage detection system especially used for detecting four types of signage: exit, wc, disabled exit and confidence zone. Experiment results demonstrates the effectiveness and the high precision of the proposed recognition system. We obtained 99.8% as a recognition rate.
