Dickinson College Financial Statement 2022: $873.4M

Dickinson College | Cumberland County Pennsylvania

Every week, patrons of Farmers on the Square can count on locating the Dickinson College Farm’s wood-fired pizza oven right at the heart of the square. Our handmade and fresh-baked pizzas reflect the seasonal fluctuations on our farm in addition to quality ingredients grown within the Cumberland Valley. In addition to wood-fired pizzas, our stand features seasonal organic vegetables, fresh salad dressings, refreshing popsicles and “our farm in a jar” through canned soups, pickled favorites, salsa, hot sauce and more!”

Sie strahlt vor Freude über ihre Auszeichnung – TH-Alumna Melanie Klaus. Für ihre Bachelorarbeit im Bereich Erneuerbare Energien wurde sie vom Solarenergieförderverein Bayern geehrt. In ihrer Bachelorarbeit im Studiengang Elektro- und Informationstechnik untersuchte sie das Zusammenspiel von Wind- und Solarenergie und den Nutzen, der sich hieraus für die regenerative Energieerzeugung erzielen lässt. Untersucht wurde also die Nutzung der natürlichen Kombination von Wind und Sonne für die Energieerzeugung. Um die Rentabilität dieser Einspeisekombination zu ermitteln, hat Melanie Klaus ein Software-Tool entwickelt, welches zur Planung und Simulation abgestimmter Photovoltaik-Wind-Kombinationen dient und bereits für die Errichtung einer Photovoltaik-Anlage zu einem Windpark eingesetzt wird.

Starting 2023 we break away the topic of solar energy standards from our standing Electrical and Energy colloquia.   We start with the following titles

IEC TC 82 Solar photovoltaic energy systems

Underwriters Laboratories 1703 PV Module Certification

ASTM E772 Standard Terminology of Solar Energy Conversion

IEEE 1562 Guide for Array and Battery Sizing in Stand-Alone Photovoltaic Systems

NEMA Solar Photovoltaic Council

NECA 412 Standard for Installing and Maintaining Photovoltaic Power Systems

NFPA 70 Articles 690-691

NFPA 70 Articles 705 & 855

International Code Council Section 1607 Photovoltaic panels or modules

ASHRAE International: 90.1 Building Energy Code & 189.1 Green Energy Code

Time permitting: Example design specification and construction contract.

"Education is simply the soul of a society as it passes from one generation to another" - G.K. Chesterton

Other standards developers and publishers are also present in this domain but this list is where we will start given that we only have an hour.   Join us today at 16:00 with the login credentials at the upper right of our home page.

Readings:

What are the hidden costs of solar panels?

Do We Have Enough Silver, Copper, And Other Materials To Keep Up With The Growth Of Solar?

Technical Committee 82 of the International Electrotechnical Commission is charged with preparing international standards for the full length of the solar energy power chain  The span of the power chain includes the light input, the cell itself, and the fittings and accessories to the end use (utilization) equipment.

Strategic Business Plan of IEC Technical Committee 82

The United States is the Global Secretariat for TC 82 through the US National Committee of the International Electrotechnical Commission (USNA/IEC) administered by the American National Standards Institute(ANSI).  Standards Michigan is a long-standing member of ANSI since our “standards journey” began at the University of Michigan in 1993.

The USNA/IEC and participates in its standards development processes; typically collaborating with global research and application engineers in the IEEE Industrial Applications Society and the IEEE Power and Energy Society.   To advance its agenda for lower #TotalCostofOwnership for US real asset executives and facility managers Standards Michigan also collaborates closely with subject matter experts who contribute to, and draw from, the knowledge base in the IEEE Education and Healthcare Facilities Committee (E&H).

The IEC permits public commenting on its draft standards; though you will need to establish login credentials:

IEC Public Commenting

Your comments will be reviewed by the IEC National Committee of the country you live in, which can decide to propose them as national input for the final draft of the IEC International Standard.  This approach makes it easier for individual nations to participate in IEC standards development processes because the resources that national standards bodies need to administer participation resides in Geneva and is managed there.  

We collaborate with the IEEE Education & Healthcare Facilities Committee which has its own platform to tracking commenting opportunities:

IEEE E&H/USNC/IEC Workspace

As of this posting, no interoperability redlines have been released for public consultation.   In large measure, IEC titles contribute to a level playing field among multi-national electrical equipment manufacturers so we should not be surprised that there are no redlines to review.   When they are released we place them on the agenda of the IEEE E&H Committee which meets 4 times monthly in European and American time zones.

2024 GROUP A PROPOSED CHANGES TO THE I-CODES | Complete Monograph 2658 Pages

2024/2025/2026 ICC CODE DEVELOPMENT SCHEDULE

“View from the Ancient Theater in Taormina to Mount Etna” c. 1880 Carl Wuttke

Safety and sustainability for any facility begins with an understanding of who shall occupy it.  University settings, with mixed-use phenomenon arising spontaneously and temporarily, present challenges and no less so in  square-footage identified as performing arts facilities.  Education communities present the largest installed base of mixed use and performing arts facilities.  A distinction is made between supervised occupants that are in secondary schools (generally under age 18) and unsupervised occupants that are in university facilities (generally above age 18).

First principles regarding occupancy classifications for performing arts facilities appear in Section 303 of the International Building Code Assembly Group A-1.  The public edition of the 2021 IBC is linked below:

2024 IBC Chapter 3: Occupancy Classification and Use


Each of the International Code Council code development groups A, B and C; fetch back to these classifications.   You can sample the safety concepts in play with an examination of the document linked below:

2019 GROUP B PROPOSED CHANGES TO THE GROUP B I-CODES

2019 GROUP B PUBLIC COMMENT AGENDA

Each of the foregoing documents are lengthy so we recommend using search terms such as “school”, “college”, ‘”university”, “auditorium”, “theater”, “children”, “student” to hasten your cut through it.

We find continuation of lowering of the lighting power densities as noteworthy.  Technical committees assembled and managed by the International Code Council, the American Society of Heating & Refrigeration Engineers and the Illumination Engineering Society are leaders in developing consensus products that drive the LED illumination transformation.

 

The revision schedule for the next tranche of ICC titles that are built upon the foundation of the IBC is linked below:

2024/2025/2026 ICC CODE DEVELOPMENT SCHEDULE

We encourage experts in education communities — facility managers, research and teaching staff, architectural and engineering students — to participate directly in the ICC Code Development process at the link below:

We reserve a place on the agenda of our standing Lively 200 colloquia on this topic.  See our CALENDAR for the next online meeting; open to everyone.

National Electrical Code Articles 690 and 691 provide electrical installation requirements for Owner solarvoltaic PV systems that fall under local electrical safety regulations.  Access to the 2023 Edition is linked below;

2023 National Electrical Code

2026 National Electrical Code Second Draft Transcript | CMP-4

Insight into the technical problems managed in the 2023 edition can be seen in the developmental transcripts linked below:

Panel 4  Public Input Report (869 pages)

Panel 4  Second Draft Comment Report (199 pages)

The IEEE Joint IAS/PES (Industrial Applications Society & Power and Energy Society) has one vote on this 21-member committee; the only pure “User-Interest” we describe in our ABOUT.  All other voting representatives on this committee represent market incumbents or are proxies for market incumbents; also described in our ABOUT.

The 2026 National Electrical Code has entered its revision cycle.  Public input is due September 7th.

We maintain these articles, and all other articles related to “renewable” energy, on the standing agenda of our Power and Solar colloquia which anyone may join with the login credentials at the upper right of our home page.   We work close coupled with the IEEE Education & Healthcare Facilities Committee which meets 4 times monthly in American and European time zones; also open to everyone.
