“Some of my favorite places to spend my dining points are at the Coffee Club’s two locations on campus. I frequently trek down to the modern New College West (NCW) storefront that overlooks Poe Field before an afternoon of studying. I also love the quaint café at Campus Club, with its homey vibe and frequent musical performances. Typically, I go for the basic, predictable iced vanilla latte. However, Coffee Club seasonally experiments with its menu and releases temporary items that reflect the weather, holidays, or mood of the campus….” Isabella Dail
As reading period and exams begin, here are some favorite spots for students to study, catch up with friends or simply have a quiet moment.
A laboratory fume hood is a specialized ventilated enclosure designed to safely contain and remove hazardous chemical fumes, vapors, dust, and aerosols generated during experiments. It consists of a cabinet-like structure with a movable sash window at the front, internal baffles, and a powerful exhaust fan that continuously draws air inward at a controlled velocity (typically 0.3–0.5 m/s). Contaminated air is ducted outside or passed through filters before release, while clean air flows in to create a protective barrier between the user and the hazardous materials.
Today at the usual hour we refresh our understanding of the best practice literature. Use the login credentials at the upper right of our home page.
School Educational Laboratories. In secondary and undergraduate teaching labs, fume hoods enable safe demonstration of core experiments involving acids, bases, or organic reactions. They protect students—who often have limited experience—from accidental exposure while building practical skills. They also reduce odors and airborne contaminants, creating a healthier learning environment and allowing more complex experiments to be included in curricula. In resource-limited schools, even basic fume hoods dramatically lower accident risks and support compliance with safety regulations.
University Research. In advanced research settings, fume hoods are critical for handling toxic, flammable, corrosive, or volatile substances (e.g., organic solvents, carcinogens, or reactive gases). They protect researchers from inhalation exposure, prevent laboratory fires or explosions, and maintain experiment integrity by minimizing cross-contamination. Regulatory standards like OSHA and ASHRAE require their use for many procedures. Without fume hoods, high-level chemical synthesis, nanomaterials research, or analytical chemistry would pose unacceptable health and safety risks, halting scientific progress.
These documents emphasize common themes like checking airflow before use, keeping work ≥6 inches inside the sash, minimizing clutter, proper sash positioning, and never using a malfunctioning hood.
A significant amount of research in the United States is conducted in research universities — over $70 billion annually, according to the National Science Foundation (LEARN MORE HERE). Unlike private industry, where facilities can be located away from population centers, many campus laboratories are located in dense populated areas because researchers enjoy their work in a lively campus setting. Keeping these facilities safe and sustainable is challenging anywhere but especially so in a setting where education and research takes place in close proximity.
One of the core documents for leading practice is ASHRAE 110 — Method of Testing Performance of Laboratory Fume Hoods. Keep in mind that in the emergent #SmartCampus a fume hood is part of an integrated system that not only includes environmental air systems but electrical, telecommunication, and fire safety systems.
ASHRAE 110 provides a starting point for assessing a wide variety of factors that influence the performance of laboratory fume hoods. The ability of a laboratory hood to provide protection for the user at the face of the hood is strongly influenced by the aerodynamic design of the hood, the method of operation of the hood, the stability of the exhaust ventilation system, the supply ventilation of the laboratory room, the work practices of the user, and other features of the laboratory in which it is installed. Therefore, there is a need for a test method that can be used to evaluate the performance including the influences of the laboratory arrangement and its ventilation system.
From the project prospectus:
Purpose. This standard specifies a quantitative and qualitative test method for evaluating fume containment of laboratory fume hoods.
Scope: his method of testing applies to conventional, bypass, auxiliary-air, and VAV laboratory fume hoods. (2) This method of testing is intended primarily for laboratory and factory testing but may also be used as an aid in evaluating installed performance.
The 2016 revision is the current version; made the following improvements to the 1995 edition:
• The test procedures now require digital collection of data rather than allowing manual data collection.
• Some modifications have been made to the test procedure. These modifications were made based on the experience of the committee members or to clarify statements in the 1995 edition of the standard.
• Informative Appendix A, which provides explanatory information, has been expanded.
• Informative Appendix B, a new nonmandatory section, provides guidance to anyone using the standard as a diagnostic tool in investigating the cause of poor hood performance.
ASHRAE has recently upgraded its public participation platform; available in the link below:
ASHRAE 110 is not a continuous maintenance document (that can change in 30 to 90 day intervals). We encourage our colleagues involved in university-affiliated research enterprises who have an idea, data and/or anecdotes to key in their idea, data or anecdote — particularly faculty and students. While we recognize that conformance professionals (i.e. “inspectors”) have a very informed point of view about safety; they may not place ideas for lower costs at the top of their agenda. It is a fine line we must hew in the education industry — respecting the experience and priorities of risk managers while at the same coming up with ideas that make laboratories safer, simpler, lower-cost and longer-lasting that may reduce their billable hours.
We find that environmental air safety goals often compete with fire safety goals and both compete with sustainability goals. Conversations about the optimal approach to converting to variable volume fume hood systems from constant flow are common:
As an ANSI accredited continuous-maintenance standards developer ASHRAE technical committees receive public comment at any time; though action on revising the standard must follow the accredited process. State level adaptations — with respect to technical specifics or compliance paths or both — are always possible. As explained elsewhere, Standards Michigan generally advocates for scalable, site specific solutions to laboratory safety system operation and maintenance, though we understand that enforcement and compliance interests prefer bright-line, single-point solutions that are easy to enforce.
All ASHRAE standards are on the agenda of our Mechanical Engineering teleconference. See our CALENDAR for our next conversation on this subject; open to everyone.

Our use of the term “Educational Settlements” captures the self-contained energy of these places — kindergartens, classrooms, quads, dining halls, dorms, and nearby squares buzzing with student life amid broader higher-ed shifts like the “demographic cliff” (declining traditional enrollments), AI integration, skills-focused curricula, and financial pressures.

We sweep through the world’s three major time zones; updating our understanding of the literature at the technical foundation of education community safety and sustainability in those time zones 24 times per day. We generally eschew “over-coding” web pages to sustain speed, revision cadence and richness of content as peak priority. We do not provide a search facility because of copyrights of publishers and time sensitivity of almost everything we do.
Our daily colloquia are typically doing sessions; with non-USA titles receiving priority until 16:00 UTC and all other titles thereafter. We assume policy objectives are established (Safer-Simpler-Lower-Cost, Longer-Lasting). Because we necessarily get into the weeds, and because much of the content is time-sensitive and copyright protected, we usually schedule a separate time slot to hammer on technical specifics so that our response to consultations are meaningful and contribute to the goals of the standards developing organization and to the goals of stewards of education community real assets — typically the largest real asset owned by any US state and about 50 percent of its annual budget.
1. Leviathan. We track noteworthy legislative proposals in the United States 118th Congress. Not many deal specifically with education community real assets since the relevant legislation is already under administrative control of various Executive Branch Departments such as the Department of Education.
We do not advocate in legislative activity at any level. We respond to public consultations but there it ends.
We track federal legislative action because it provides a stroboscopic view of the moment — the “national conversation”– in communities that are simultaneously a business and a culture. Even though more than 90 percent of such proposals are at the mercy of the party leadership the process does enlighten the strengths and weakness of a governance system run entirely through the counties on the periphery of Washington D.C. It is impossible to solve technical problems in facilities without sensitivity to the zietgeist that has accelerated in education communities everywhere.

NSF Internationaldevelops a standard for one of the centerpiece safety technologies for a large revenue driver in research universities. The landing page for its biosafety cabinetry product, installation, operation and maintenance standard is linked below:
This Standard applies to Class II (laminar flow) biosafety cabinetry designed to minimize hazards inherent in work with agents assigned to biosafety levels 1, 2, 3, or 4. It also defines the tests that shall be passed by such cabinetry to meet this standard. NSF 49 includes basic requirements for the design, construction, and performance of biosafety cabinets that are intended to provide personnel, product, and environmental protection; reliable operation; durability and structural stability; cleanability; limitations on noise level; illumination; vibration; and motor/blower performance.

Recap of the May meetings of the Industrial & Commercial Power Systems Conference in Las Vegas. The conference ended the day before the beginning of the 3-day Memorial Day weekend in the United States so we’re pressed for time; given all that happened.
We can use our last meeting’s agenda to refresh the status of the issues.
We typically break down our discussion into the topics listed below:
Codes & Standards:
While IAS/I&CPS has directed votes on the NEC; Mike is the only I&CPS member who is actually submitting proposals and responses to codes and standards developers to the more dominant SDO’s — International Code Council, ASHRAE International, UL, ASTM International, IEC & ISO. Mike maintains his offer to train the next generation of “code writers and vote getters”
Performance-based building premises feeder design has been proposed for the better part of ten NEC revision cycles. The objective of these proposals is to reduce material, labor and energy waste owed to the branch and feeder sizing rules that are prescriptive in Articles 210-235. Our work in service and lighting branch circuit design has been largely successful. A great deal of building interior power chain involves feeders — the network upstream from branch circuit panels but down stream from building service panel.
Our history of advocating for developing this approach, inspired by the NFPA 101 Guide to Alternative Approaches to Life Safety, and recounted in recent proposals for installing performance-based electrical feeder design into the International Building Code, appears in the link below:
Access to this draft paper for presentation at any conference that will receive it — NFPA, ICC or IEEE (or even ASHRAE) will be available for review at the link below:
NFPA 110 Definitions of Public Utility v. Merchant Utility
NFPA 72 “Definition of Dormitory Suite” and related proposals
Buildings:
Renovation economics, Smart contracts in electrical construction. UMich leadership in aluminum wiring statements in the NEC should be used to reduce wiring costs.
This paper details primary considerations in estimating the life cycle of a campus medium voltage distribution grid. Some colleges and universities are selling their entire power grid to private companies. Mike has been following these transactions but cannot do it alone.
Variable Architecture Multi-Island Microgrids
District energy:
Generator stator winding failures and implications upon insurance premiums. David Shipp and Sergio Panetta. Mike suggests more coverage of retro-fit and lapsed life cycle technicals for insurance companies setting premiums.
Reliability:
Bob Arno’s leadership in updating the Gold Book.
Mike will expand the sample set in Table 10-35, page 293 from the <75 data points in the 1975 survey to >1000 data points. Bob will set up meeting with Peyton at US Army Corps of Engineers.
Reliability of merchant utility distribution systems remains pretty much a local matter. The 2023 Edition of the NESC shows modest improvement in the vocabulary of reliability concepts. For the 2028 Edition Mike submitted several proposals to at least reference IEEE titles in the distribution reliability domain. It seems odd (at least to Mike) that the NESC committees do not even reference IEEE technical literature such as Bob’s Gold Book which has been active for decades. Mike will continue to propose changes in other standards catalogs — such as ASTM, ASHRAE and ICC — which may be more responsive to best practice assertions. Ultimately, improvements will require state public utility commission regulations — and we support increases in tariffs so that utilities can afford these improvements.
Mike needs help from IEEE Piscataway on standard WordPress theme limitations for the data collection platform.
Mike will update the campus power outage database.
Healthcare:
Giuseppe Parise’s recent work in Italian power grid to its hospitals, given its elevated earthquake risk. Mike’s review of Giuseppe’s paper:
Mike and David Shipp will prepare a position paper for the Harvard Healthcare Management Journal on reliability advantages of impedance grounding for the larger systems.
The Internet of Bodies
Forensics:
Giuseppe’s session was noteworthy for illuminating the similarity and differences between the Italian and US legal system in handling electrotechnology issues.
Mike will restock the committee’s library of lawsuits transactions.
Ports:
Giuseppe updates on the energy and security issues of international ports. Mike limits his time in this committee even though the State of Michigan has the most fresh water international ports in the world.
A PROPOSED GUIDE FOR THE ENERGY PLAN AND ELECTRICAL INFRASTRUCTURE OF A PORT
Other:
Proposals to the 2028 National Electrical Safety Code: Accepted Best Practice, exterior switchgear guarding, scope expansion into ICC and ASHRAE catalog,
Apparently both the Dot Standards and the Color Books will continue parallel development. Only the Gold Book is being updated; led by Bob Arno. Mike admitted confusion but reminded everyone that any references to IEEE best practice literature in the NFPA catalog, was installed Mike himself (who would like some backup help)
Mike assured Christel Hunter (General Cable) that his proposals for reducing the 180 VA per-outlet requirements, and the performance-base design allowance for building interior feeders do not violate the results of the Neher-McGrath calculation used for conductor sizing. All insulation and conducting material thermal limits are unaffected.
Other informal discussions centered on the rising cost of copper wiring and the implications for the global electrotechnical transformation involving the build out of quantum computing and autonomous vehicles. Few expressed optimism that government ambitions for the same could be met in any practical way.
Are students avoiding use of Chat GPT for energy conservation reasons? Mike will be breaking out this topic for a dedicated standards inquiry session:
A conversation with Bjorn Lomborg, a visiting fellow at the Hoover Institution, the president of the Copenhagen Consensus Center, and one of the foremost climate experts in the world today. His new book — “False Alarm: How Climate Change Panic Costs Us Trillions, Hurts the Poor, and Fails to Fix the Planet” — is an argument for treating climate as a serious problem but not an extinction-level event requiring such severe and drastic steps as rewiring a large part of the culture and the economy.

Water is essential for sanitation and hygiene — and proper sanitation is essential for protecting water sources from contamination and ensuring access to safe drinking water. Access to safe water and sanitation is crucial for preventing the spread of waterborne diseases, which can be transmitted through contaminated water sources or poor sanitation practices. Lack of access to safe water and sanitation can lead to a range of health problems, including diarrheal diseases, cholera, typhoid, and hepatitis A.
On the other hand, poor sanitation practices, such as open defecation, can contaminate water sources, making them unsafe for drinking, bathing, or cooking. This contamination can lead to the spread of diseases and illness, particularly in developing countries where access to clean water and sanitation facilities may be limited.

* The evolution of building interior water systems has undergone significant changes over time to meet the evolving needs of society. Initially, water systems were rudimentary, primarily consisting of manually operated pumps and gravity-fed distribution systems. Water was manually fetched from wells or nearby sources, and indoor plumbing was virtually nonexistent.
The Industrial Revolution brought advancements in plumbing technology. The introduction of pressurized water systems and cast-iron pipes allowed for the centralized distribution of water within buildings. Separate pipes for hot and cold water became common, enabling more convenient access to water for various purposes. Additionally, the development of flush toilets and sewage systems improved sanitation and hygiene standards.
In the mid-20th century, the advent of plastic pipes, such as PVC (polyvinyl chloride) and CPVC (chlorinated polyvinyl chloride), revolutionized plumbing systems. These pipes offered durability, flexibility, and ease of installation, allowing for faster and more cost-effective construction.
The latter part of the 20th century witnessed a growing focus on water conservation and environmental sustainability. Low-flow fixtures, such as toilets, faucets, and showerheads, were introduced to reduce water consumption without compromising functionality. Greywater recycling systems emerged, allowing the reuse of water from sinks, showers, and laundry for non-potable purposes like irrigation.
With the advancement of digital technology, smart water systems have emerged in recent years. These systems integrate sensors, meters, and automated controls to monitor and manage water usage, detect leaks, and optimize water distribution within buildings. Smart technologies provide real-time data, enabling better water management, energy efficiency, and cost savings.
The future of building interior water systems is likely to focus on further improving efficiency, sustainability, and water quality. Innovations may include enhanced water purification techniques, decentralized water treatment systems, and increased integration of smart technologies to create more intelligent and sustainable water systems.
The first mover in building interior water supply systems can be traced back to the ancient civilizations of Mesopotamia, Egypt, and the Indus Valley. However, one of the earliest known examples of sophisticated indoor plumbing systems can be attributed to the ancient Romans.
The Romans were pioneers in constructing elaborate water supply and distribution networks within their cities. They developed aqueducts to transport water from distant sources to urban centers, allowing for a centralized water supply. The water was then distributed through a network of lead or clay pipes to public fountains, baths, and private residences.
One notable example of Roman plumbing ingenuity is the city of Pompeii, which was buried by the eruption of Mount Vesuvius in 79 AD. The excavation of Pompeii revealed a well-preserved plumbing system that included indoor plumbing in some houses. These systems featured piped water, private bathrooms with flushing toilets, and even hot and cold water systems.
The Romans also invented the concept of the cloaca maxima, an ancient sewer system that collected and transported wastewater away from the city to nearby bodies of water. This early recognition of the importance of sanitation and wastewater management was a significant advancement in public health.
While the Romans were not the only ancient civilization to develop indoor plumbing systems, their engineering prowess and widespread implementation of water supply and sanitation infrastructure make them a key player in the history of building interior water systems.
