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

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

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

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.

Today we walk through literature governing the safety and sustainability of the open space features of education community estates.   Unlike the titles for the building envelope, which are known to most design professionals and contractors, the standards for grounds and landscaping are widely scattered; many of them occupational safety related; created, administered and enforced by units of government.

During the fair seasons we examine the moment in landscape, garden, tree and water literature.  We also track titles about the reclamation of building roofs for permeable surfaces and gardens.

During the winter months in the northern hemisphere we include snow and ice management; while covering summer month technologies for southern hemisphere (and vice-versa).  Snowfalls in the southern hemisphere are mainly contained to the highlands and mountain ranges, which are almost exclusively in Victoria and Southern New South Wales, as well as the mountains in Tasmania.   Winter does not pose as much of a cost burden to education facilities in the southern hemisphere as it does in the northern hemisphere.

Landscape standards refer to guidelines or regulations that specify the requirements for the design, installation, and maintenance of outdoor spaces such as parks, gardens, streetscapes, and public spaces. Landscape standards typically cover various aspects of landscape design, including vegetation selection, planting arrangements, irrigation systems, hardscape materials, and lighting.

These standards may be set by government agencies at the federal, state, or local level, or by professional organizations such as the American Society of Landscape Architects (ASLA). Landscape standards aim to ensure that outdoor spaces are safe, functional, and aesthetically pleasing while also promoting sustainability and environmental protection.

Landscape standards may also address issues such as accessibility for people with disabilities, water conservation, stormwater management, and erosion control. They may vary depending on the specific location, climate, and intended use of the outdoor space. Compliance with landscape standards may be required for approval of development projects, public funding, or other permits.

We track the standards catalog of two ANSI-accredited standards developers:

American Hort

Tree Care Industry Association

Additional practice titles applicable to accessory systems:

ASABE/ICC 802 Landscape Irrigation Sprinkler and Emitter Standard 

National Electrical Code: Article 411 Low-Voltage Lighting

Upcode Article 411

National Electrical Code: Article 225: Outside Branch Circuits and Feeders

Illumination Engineering Society (Lighting Library)

Land F/X: Landscape Lighting, Codes, Guidelines and Techniques  

OSHA Landscape and Horticultural Services

As a cross-cutting subject involving soil and water and sun many other standards developers, and all levels of government, produce best practice literature for today’s topic.  We’ll have a look at what’s moving among those.

The World Soil Museum hosts a range of educational programs and workshops for students, researchers, and other visitors who are interested in learning more about soil science. These programs cover topics such as soil classification, soil management, and soil conservation, and they are designed to help people understand the vital role that soils play in supporting agriculture, ecosystems, and human societies around the world.

Life-cycle cost of education community settings are informed by climate change assumptions.  In addition to the flow of research money to faculty for laboratory space, graduate student support, supercomputer installations, conference travel; these assumptions inform the architectural character of a campus — i.e. the design and operation its buildings and infrastructure.  These assumptions swing back and forth over these eternal institutions with cyclical assumptions about global cooling and global warming.  In the late 1960’s academic researchers found evidence of global cooling.  Fifty years on academic researchers assume the earth is warming.  We just roll with it as we do with all the other policy “givens” we accommodate.    Stewardship of the planet — keeping it clean for those who follow us — Yes.  Catastrophilia — the love of catastrophone so well documented in history — not so much.

As with all emotional issues, language changes mightily.  We refer you to our journey through technical standard language HERE.

According to a report by the Congressional Research Service, federal funding for climate research and related activities totaled approximately $13.8 billion in fiscal year 2020. This funding was distributed across various agencies and programs, including the National Science Foundation’s Climate and Large-Scale Dynamics program, National Oceanic and Atmospheric Administration’s climate Program Office, and the Department of Energy’s Office of Science.

Not included in this figure is the opportunity cost and loss of brand identity of not conforming to the climate change agenda.

Many land grant colleges and universities are stewards of agricultural facilities that require reliable electrical power that is safe and sustainable for livestock and animal habitat for sporting.

FREE ACCESS: 2023 National Electrical Code

The premise wiring rules for hazardous university owned buildings have been relatively stable.  Electrical professionals are guided by:

  1. Farm Load Calculations of Part V of Article 220,
  2. Corrosion mitigation with appropriate specification of power chain wiring
  3. Stray voltage and the equipotential plane
  4. Interactivity with regulated utility power sources.

Public response to the First Draft of the 2026 National Electrical Code will be received until August 28, 2024.  We coordinate our approach to the entire NFPA electrical suite with the IEEE Education & Healthcare Facilities Committee which meets 4 times monthly.  We typically refer to previous transcripts of technical committee actions to inform any changes (improvements) that we propose, if any:
