ANSI Standards Action Weekly Edition
Starting 2023 we break down our coverage of education community energy codes and standards into two tranches:
Energy 200: Codes and standards for building premise energy systems. (Electrical, heating and cooling of the building envelope)
Standards Michigan: Building Transformers are Oversized and What We Are Doing About It
(Hint: We are routinely “outvoted” on the National Electrical Code by stakeholders whose revenue depends upon oversized transformers.)
National Electrical Manufacturers Association (Free Download): Benefits of Electrical Submeters
Energy Star Data Trends: Energy Use in Residence Halls
University of Alabama: Which Residence Hall Can Save the Most Energy?
Energy 400: Codes and standards for energy systems between campus buildings. (District energy systems including interdependence with electrical and water supply)
ΔE=ΔKE+ΔPE+ΔU=Q−W |
A different “flavor of money” runs through each of these domains and this condition is reflected in best practice discovery and promulgation. Energy 200 is less informed by tax-free (bonded) money than Energy 400 titles.
Some titles cover safety and sustainability in both interior and exterior energy domains so we simply list them below:
ASME Boiler Pressure Vessel Code
ASHRAE International 90.1 — Energy Standard for Buildings Except Low-Rise Residential Buildings
International Code Council 2021 Energy Conservation Code
cdpACCESS | Energy Complete Monograph for all 2021 cycle energy proposals (1270 pages)
International Code Council 2021 International Green Construction Code
NFPA 855 Standard for the Installation of Stationary Energy Storage Systems
IEEE Electrical energy technical literature
ASTM Energy & Utilities Overview
Underwriters Laboratories Energy and Utilities
There are other ad hoc and open-source consortia that occupy at least a niche in this domain. All of the fifty United States and the Washington DC-based US Federal Government throw off public consultations routinely and, of course, a great deal of faculty interest lies in research funding.
Please join our daily colloquia using the login credentials at the upper right of our home page. We are also rolling out another facility — [MEETING POINT] — which should be ready for use sometime mid-2023.

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.

Question: How many households can be supplied with 1 megawatt of power and how large would the solar panel be?
The number of square meters of solar panels required to generate 1 megawatt (MW) of power depends on several factors, including the efficiency of the solar panels, the amount of sunlight available in the location where the solar panels are installed, and the specific technology used.
On average, solar panels have a conversion efficiency of about 15-20%, which means that for every square meter of solar panel area, you can expect to generate between 150 and 200 watts of power in direct sunlight.
So, to generate 1 MW of power, you would need between 5,000 and 6,667 square meters of solar panels (assuming an average efficiency of 17.5%).
There are 2.58999 square meters in one square mile.
To convert 6,667 square meters to square miles, we can divide 6,667 by 2,589.99:
6,667 sq meters / 2,589.99 sq meters/sq mile = 2.572 square miles (rounded to three decimal places).
Answer: Therefore 2.572 square miles of solar panels are required to supply 9345 household of power for 1 hour.
The number of households that can be supplied by 1 megawatt of power depends on a variety of factors, including the amount of electricity each household consumes, the time of day, and the season.
However, as a rough estimate, the US Energy Information Administration (EIA) reports that in 2020, the average US household consumed about 9,369 kilowatt-hours (kWh) of electricity per year, which is equivalent to an average of 0.107 MW of power.
Based on this average, 1 MW of power could supply approximately 9,345 households (1,000,000 watts / 0.107 MW per household) with electricity for one hour, assuming that all households are consuming the average amount of electricity.
Again, this is a rough estimate, and the actual number of households that can be supplied by 1 MW will depend on various factors such as the region, the time of day, and the actual energy consumption of each household.
Discussion: A typical residential lot is one-half acre. Rounding 9345 households to 10,000 households; the households themselves have a footprint of 7.8125 square miles; with 1/3rd of the 2.572 square miles for 1 megawatt taken up by the panels.
Much economic activity in the global standards system involves products — not interoperability standards. Getting everything to work together — cost effectively and simpler — is our raison d’etre.
Manufacturers, testing laboratories, conformance authorities (whom we call vertical incumbents) are able to finance the cost of their advocacy — salaries, travel, lobbying, administration — into the cost of the product they sell to the end user (in our cases, estate managers in educational settlements). Our readings of the intent of this technical committee is to discover and promulgate best practice for “systems of products” — i.e. ideally interoperability characteristics throughout the full span of the system life cycle.
To quote Thomas Sowell:
“There are no absolute solutions to human problems, there are only tradeoffs.”
Many problems have no solutions, only trade-offs in matters of degree. We explain our lament over wicked problems in our About.
The United States National Committee of the International Electrotechnical Commission (USNA/IEC) seeks participants and an ANSI Technical Advisory Group (US TAG) Administrator for an IEC subcommittee (Multi-Agent System) developing standards for power system network management. From the project prospectus:
Standardization in the field of network management in interconnected electric power systems with different time horizons including design, planning, market integration, operation and control. SC 8C covers issues such as resilience, reliability, security, stability in transmission-level networks (generally with voltage 100kV or above) and also the impact of distribution level resources on the interconnected power system, e.g. conventional or aggregated Demand Side Resources (DSR) procured from markets.
SC 8C develops normative deliverables/guidelines/technical reports such as:
– Terms and definitions in area of network management,
– Guidelines for network design, planning, operation, control, and market integration
– Contingency criteria, classification, countermeasures, and controller response, as a basis of technical requirements for reliability, adequacy, security, stability and resilience analysis,
– Functional and technical requirements for network operation management systems, stability control systems, etc.
– Technical profiling of reserve products from DSRs for effective market integration.
– Technical requirements of wide-area operation, such as balancing reserve sharing, emergency power wheeling.
Individuals who are interested in becoming a participant or the TAG Administrator for SC 8C: Network Management are invited to contact Adelana Gladstein at agladstein@ansi.org as soon as possible.
This opportunity, dealing with the system aspects of electrical energy supply (IEC TC 8), should at least interest electrical engineering research faculty and students involved in power security issues. Participation would not only provide students with a front-row seat in power system integration but faculty can collaborate and compete (for research money) from the platform TC 8 administers. We will refer it to the IEEE Education & Healthcare Facilities Committee which meets online 4 times monthly in European and American time zones.
