ANSI Standards Action Weekly Edition

Iowa State University

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

US Department of Energy Office of Scientific and Technical Information: How college dormitory residents change to save energy during a competition-based energy reduction intervention

Energy Star Data Trends: Energy Use in Residence Halls

University of Alabama: Which Residence Hall Can Save the Most Energy?

International Energy Conservation Code

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=QW

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 90 Building Energy 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.

Soybeans play a critical role in the food chain as a source of protein and oil for human consumption, animal feed, food processing, industrial applications, and sustainable agricultural practices. They are a versatile and widely used crop that contributes to various aspects of the global food system.

Peeking Inside the Black-Box_ A Survey on Explainable Artificial Intelligence (XAI)

ABSTRACT: At the dawn of the fourth industrial revolution, we are witnessing a fast and widespread adoption of artificial intelligence (AI) in our daily life, which contributes to accelerating the shift towards a more algorithmic society. However, even with such unprecedented advancements, a key impediment to the use of AI-based systems is that they often lack transparency. Indeed, the black-box nature of these systems allows powerful predictions, but it cannot be directly explained. This issue has triggered a new debate on explainable AI (XAI). A research field holds substantial promise for improving trust and transparency of AI-based systems. It is recognized as the sine qua non for AI to continue making steady progress without disruption. This survey provides an entry point for interested researchers and practitioners to learn key aspects of the young and rapidly growing body of research related to XAI. Through the lens of the literature, we review the existing approaches regarding the topic, discuss trends surrounding its sphere, and present major research trajectories.

“The wireless age has brought us closer together,

yet we must work to ensure that it does not divide us.”

When the electric grid and the internet are down and there is no cell service, radio can still work to help communities stabilize.   Starting 2024 we will break down our coverage of the radio frequency technology standards used in educational settlements into into two categories:

Radio 300: Security and maintenance radio.  These usually use a single radio channel and operate in a half-duplex mode: only one user on the channel can transmit at a time, so users in a user group must take turns talking. The radio is normally in receive mode so the user can hear all other transmissions on the channel. When the user wants to talk he presses a “push-to-talk” button, which turns off the receiver and turns on the transmitter; when he releases the button the receiver is activated again. Multiple channels are provided so separate user groups can communicate in the same area without interfering with each other.

Note that a core title in this domain — NFPA 1802 Standard on Two-Way, Portable RF Voice Communications Devices for Use by Emergency Services Personnel in the Hazard Zone — is part of an NFPA catalog reorganization.  Best practice content will be rolled into NFPA 1300 Standard on Fire and Emergency Service Use of Thermal Imagers, Two-Way Portable RF Voice Communication Devices, Ground Ladders, and Fire Hose, and Fire Hose Appliances.  

As of this posting APCO International has no public consultations on any titles in its public safety radio standards catalog.

Radio 400: Student radio.  College radio stations are typically considered to be public radio radio stations in the way that they are funded by donation and grants.  The term “Public radio” generally refers to classical music, jazz, and news. A more accurate term is community radio, as most staff are volunteers, although many radio stations limit staff to current or recent students instead of anyone from the local community.  There has been a fair amount of drama over student-run radio station history; a topic we steer away from.

The Low Power FM radio service was created by the Commission in January 2000.  LPFM stations are authorized for noncommercial educational broadcasting only (no commercial operation) and operate with an effective radiated power (ERP) of 100 watts (0.1 kilowatts) or less, with maximum facilities of 100 watts ERP at 30 meters (100 feet) antenna height above average terrain.  The approximate service range of a 100 watt LPFM station is 5.6 kilometers (3.5 miles radius).  LPFM stations are not protected from interference that may be received from other classes of FM stations.

We follow — but do not respond — to consultations on titles covering the use of radio frequencies for the Internet of Things.  At the moment, most of that evolution happens at the consumer product level; though it is wise to contemplate the use of the electromagnetic spectrum during widespread and extended loss of broadband services.

We do not include policy specifics regarding the migration of National Public Radio beyond cultural content into political news; though we acknowledge that the growth of publicly financed radio domiciled in education communities is a consideration in the technology of content preparation informed by the Public Broadcasting Act of 1967.

We drill into technical specifics of the following:

  • Radios used for campus public safety and campus maintenance
  • Student-run campus radio stations licensed by the Federal Communications Commission as Low Power FM (LPFM)
  • Facilities for regional broadcast of National Public Radio operating from education communities
  • Off-campus transmission facilities such as broadcast towers.
  • Grounding, bonding, lightning protection of transmission and receiving equipment on buildings
  • Broadcast studio electrotechnologies

Radio technology is regulated by the Federal Communications Commission with no ANSI-accredited standards setting organizations involved in leading practice discovery and promulgation.  Again, we do not cover creative and content issues.  Join us today at 11 AM/ET using the login credentials at the upper right of our home page.
