Professor Karl Siebert, who teaches FDSC 4300, The Science and Technology of Beer, demonstrates how to properly pour a beer and discusses the sensory experience of beer appreciation. In a recent study, Siebert identified the key component in a ‘perfect’ head of beer: a barley protein known as Lipid Transport Protein 1 or LPT1.
We were doing microgrids before microgrids were cool. We did not call our school boiler plants or campus district energy systems “microgrids” until the EPACT flooded the electrical power industry with a new cadre of policy makers, regulators and litigators and we were forced into a vocabulary upgrade.
We resume our engagement (and advocacy) for a few concepts which have tracked in the NFPA and IEEE standards development catalogs since the early 1990’s:
Nudge development of the National Electrical Code to recognize that loss of electrical power presents (i.e. reliability, availability) a greater hazard, and more frequent hazard, than wiring fire hazard.
The application of stand-alone AC to DC inverters in the 100 – 1000 watt range to convert DC power from an automobile to households. A portable vehicle to home 120 VAC outlet strip is effectively a “microgrid” and costs less than $100 not including the extension cords.
Expansion of the hybrid vehicle fittings with a built-in inverter to provide power to households in the 1000-2000 watt range. In contemporary parlance this arrangement is now referred to as “vehicle to home” (different than vehicle to grid)
Relaxation of NEC prohibitions against the sharing of residential backup generators and electric storage equipment between two or more separate houses. This can reduce cost significantly. Earthing, ground fault, disconnect, overcurrent protection can easily be solved if the vertical incumbents we describe in our ABOUT stop voting against us in the National Electrical Code
Stepping up the backup power systems that maintain the needed power for neighborhood internet access. Not all students and faculty live on campus.
Policy makers and regulators should think in terms of setting standards for 10-day, 30-day and 90-day survivability contingencies to limit civil unrest.
Preservation of contingencies with a judicious combination of absorption and electric chillers no matter what the electric rate. During a major regional contingency power is priceless.
Promote a “cultural change” among specifiers and university design guideline writers to permit use of aluminum wiring which cost 1/3 less than copper wiring. Use of aluminum wiring for backup “swing feeders” at medium voltage reduces the cost of an additional contingency by 2/3rds.
Reduce National Electrical Code circuit sizing rules so that distribution transformers within buildings can be reduced, thereby reducing material, heat waste and the reduction of wet-stacking in backup generators which reduces reliability.
This should be enough for an hour. We continue the conversation 4 times monthly with the IEEE Education & Healthcare Facilities Committee. Feel free to join us today with the login credentials at the upper right of our home page.

Abstract: Increasing distributed topology design implementations, uncertainties due to solar photovoltaic systems generation intermittencies, and decreasing battery costs, have shifted the direction towards integration of battery energy storage systems (BESSs) with photovoltaic systems to form renewable microgrids (MGs). Specific benefits include, but are not limited to, seamless switching and islanding operations during outages and ancillary grid services. The evolution of battery chemistries and other components has also further enhanced practicality; however, developing these multifaceted MGs involves complexity in the design process. Consequently, stakeholders rely on connection standards and operational requirements to guarantee reliable and safe grid-connected operations.
This paper presents a technical overview of battery system architecture variations, benchmark requirements, integration challenges, guidelines for BESS design and interconnection, grid codes and standards, power conversion topologies, and operational grid services. In addition, a comprehensive review of the control strategies for battery equalization, energy management systems, communication, control of multiple BESSs, as well as a discussion on protection blinding and intentional islanding using BESSs is also provided. Finally, a discussion of the islanded and black start operation results for time-based analysis and standard validation of a 3MW/9MWh BESS in a grid-connected MG at the Florida International University (FIU) Engineering Campus is presented.

Standards are the seed corn for compliance revenue; hence the hegemony of conformance and enforcement enterprises that dominate the global standards system.
Accreditation is a relatively recent breakout topic so we approach it gently; respectful of the business models of the hundreds of education community charitable associations involved in the safety and sustainability of the physical spaces of education communities.
Later in 2024 we will sort through other issues in the credentialing domain:
Accreditation 200: Recent innovations in credentialing
Q. There are about 150 hospitals in the USA with the word “university” in their name. Are they tax-exempt? Should they be? A. Whether a hospital with “university” in its name is tax-exempt depends on various factors, including its ownership, structure, and purpose. Non-profit hospitals, including those affiliated with universities, may qualify for tax-exempt status under certain conditions. However, the mere presence of “university” in the name does not automatically confer tax-exempt status. Tax-exempt status, the hospital’s activities, such as providing charity care, medical education, and research, are typically considered.

Accreditation and certification are relatively modern concepts that have evolved over time as formalized methods of establishing and maintaining standards in various fields. The concept of accreditation or certification, as it is understood today, may not have existed in the same form in the distant past. However, there were likely individuals or groups who played roles similar to that of accreditation or certification specialists in history, although the formalized systems of accreditation or certification that exist today were not present.
For example, in ancient times, there were guilds and associations in various professions that set standards for their members, oversaw training and apprenticeship programs, and ensured the quality of their work. These guilds and associations, which existed in various civilizations such as ancient Egypt, Greece, and Rome, could be seen as early forms of accreditation or certification bodies.
Similarly, in religious contexts, there were individuals who held authority to certify or accredit others. For instance, in medieval Europe, there were religious orders, such as the Knights Templar, who were known for their specialized skills and were often called upon to certify the expertise of others in their areas of knowledge, such as architecture or finance.
In the field of education, ancient universities and centers of learning, such as the ancient Indian Nalanda University or the Islamic madrasas, could also be seen as early forms of accreditation or certification bodies, where scholars were recognized and certified based on their knowledge and expertise.
However, it’s important to note that the formalized systems of accreditation or certification that we are familiar with today, with standardized processes, documentation, and oversight, have developed over time and are relatively modern phenomena. The history of accreditation or certification is complex and multifaceted, with various practices and traditions that have evolved and influenced the modern systems we have today.
