“I know that I am mortal by nature, and ephemeral;

but when I trace at my pleasure the windings to and fro of the heavenly bodies,

I no longer touch Earth with my feet:

I stand in the presence of Zeus himself and take my fill of ambrosia.”

— Ptolemy, “Mathematike Syntaxis” 150 A.D

Planetariums in schools and colleges play a central in enhancing astronomy and astrophysics education. They provide immersive experiences that can ignite students’ interest and curiosity about the universe, making complex astronomical concepts more comprehensible and engaging.  Observatories do much that but with direct access to telescopes and other observational tools — frequently away from campus — thus allowing them to engage in hands-on learning and real-time data collection.

Establishing research and teaching programs present special occupancy challenges. The cost of high-quality telescopes and equipment, along with the need for a suitable location with minimal light pollution, can be substantial. Additionally, schools require trained staff to guide students in using the equipment and interpreting data. Weather conditions and geographical location also impact the effectiveness of observatories. Despite these hurdles, the educational value of observatories is immense, providing students with unique opportunities to explore the universe and cultivate a passion for scientific inquiry.

Today we examine both occupancies using our SAFER-SIMPLER-LOWER COST-LONGER LASTING discipline.  Use the login credentials at the upper right of our home page at the usual hour.

Today we run through recent action in fire safety best practice literature.  Even though fire safety technologies comprise about 2-4 percent of a new building budget, the influence of the fire safety culture dominates all aspects campus safety; cybersecurity of public safety communication technology for example.

A small sample of the issues we have tracked in the past: (2002-2023).  Items in RED indicate success in reducing cost with no reduction in safety (i.e. successful rebuttal, typically market-making by incumbents)

  • Limiting vendor lock-in (promote interoperability) in building additions.
  • Limiting the tendency to lowball first cost in order to achieve vendor lock-in later in the facility life-cycle
  • Dormitory kitchen fire safety

Fire Safety of University Dormitory Based on Bayesian Network

  • Clarification of mixed-occupancy classifications (occupant loading)
  • Fixed interval (rather than risk-informed) inspection, testing and maintenance of fire alarm and protection system components
  • Fire alarm system upgrades during renovation

Gamification Teaching in School Fire Safety

  • Mixed zone and addressable alarm system wiring
  • Wireless initiation devices
  • Integrated fire protection systems (NFPA 3&4)
  • Portable fire extinguishers (NFPA 10)

Hospital Evacuation under Fire

  • Alarm system re-set procedures
  • Sprinkler system coverage for animals in research
  • Scalability of fire safety professional certification
  • Sprinklering of off-campus student housing
  • Advocating central (or campus district) fire pump systems

One of the newer issues to revisit over the past few years is the fire safety of tents.   Many colleges and universities are setting up large commercial tents outside buildings (within range of Wi-Fi) for students to congregate, study and dine.  We are also seeing back and forth on fire safety in theatrical performance venues in the International Code Council building safety catalog.

We approach these titles with an eye toward driving risk-informed, performance requirements that reduce risk and cost for the user interest; while recognizing the responsibility of competitor stakeholders.   It is not a friendly space for the user-interest who seeks to optimally resolve the competing requirements of safety and economy.   Vertical incumbents completely dominate this domain.

“Creation of humanity by Prometheus as Athena looks on”

Fire safety leadership usually finds itself involved in nearly every dimension of risk on the #WiseCampus; not just the built environment but security of interior spaces with combustibles but along the perimeter and within the footprint of the education community overall.

The Campus Fire Marshal, for example, usually signs the certificate of occupancy for a new building but may be drawn into meetings where decisions about cybersecurity are made.   Fire protection systems coincide with evacuation systems when there is no risk and both may be at risk because of cyber-risk.

The job description of a campus fire safety official is linked below offers some insight into why fire safety technologies reach into every risk dimension:

The development of the highest level fire safety consensus product in the world is led by the British Standards Institute, under the administration of the International Standardization Organization, with Committee E05 on Fire Standards of  ASTM International as the US Technical Advisory Group Administrator.  The business plan and the map of global participants is linked below:

BUSINESS PLAN ISO/TC 92 Fire safety EXECUTIVE SUMMARY

The consensus products developed by TC 92 are intended to save lives, reduce fire losses, reduce technical barriers to trade, provide for international harmonization of tests and methods and bring substantial cost savings in design. ISO/TC 92 standards are expected to be of special value to developing countries, which are less likely to have national standards.  As with all ISO standards, the TC 92 consensus product is a performance standard suitable for use in prescriptive regulations and provide for a proven route to increased fire safety.

We do not advocate in this standard at the moment; we only track it.  The International Fire Code and the Fire Code have been our priorities since 2006.  The fire safety space is well populated with knowledgeable facility professionals because conformity budgets in the fire safety world — i.e. the local or state fire marshal — usually has a budget.  When you have a budget you usually have people keeping pace with best practice.

We encourage our colleagues in the United States on either the business or academic side of the education facility industry to communicate directly with ANSI’s ISO Team and/or the ASTM Contact: Tom O’Toole, 100 Barr Harbor Drive, West Conshohocken, PA 19428-2959 Phone: (610) 832-9739, Email: [email protected]

Energy Standard for Sites & Buildings: Metering

December 17, 2024
[email protected]
No Comments

Section 8 Key points:

Metering for New Buildings: New buildings larger than 25,000 square feet must be equipped with metering to measure the electrical energy usage of the entire building.

Tenant Spaces: In buildings with tenant spaces, individual tenant spaces larger than 10,000 square feet must also be separately metered.

Subsystem Metering: Buildings with electrical loads exceeding specified thresholds must have additional metering to measure energy use for various subsystems, including:

HVAC systems
Lighting systems
Plug loads
Process loads

These metering requirements are intended to help building owners and operators monitor energy consumption, identify opportunities for energy savings, and comply with building energy codes and standards.

Despite best intentions a fair question to ask: What does over metering look like? (University of Alberta Research)

University of Michigan

The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) is an ANSI-accredited continuous-maintenance standards developer (a major contributor to what we call a regulatory product development “stream”).   Continuous maintenance means that changes to titles in its catalog can change in as little as 30-45 days.  This is meaningful to jurisdictions that require conformance to the “latest” version of ASHRAE 90.1

Among the leading titles in its catalog is ASHRAE 90.1 Energy Standard for Sites and Buildings Except Low-Rise Residential Buildings.  Standard 90.1 has been a benchmark for commercial building energy codes in the United States and a key basis for codes and standards around the world for more than 35 years.  Free access to ASHRAE 90.1 version is available at the link below:

READ ONLY Version of 2022 ASHRAE 90.1

If you cannot access it with the link above, try the link below and select 90.1 from the title list:

Current Popular ASHRAE Standards and Guidelines

Chapter 9: Lighting, begins on Page 148, and therein lie the tables that are the most widely used metrics (lighting power densities) by electrical and illumination engineers for specifying luminaires and getting them wired and controlled “per code”.   Many jurisdictions provide access to this Chapter without charge.  Respecting ASHRAE’s copyright, we will not do so here but will use them during today’s Illumination Colloquium, 16:00 UTC.

Keep in mind that recently ASHRAE expanded the scope of 90.1 to include energy usage in the spaces between buildings:

25 January 2023: Newly Released ASHRAE 90.1-2022 Includes Expanded Scope For Building Sites

At this time, there are no redlines open for public comment

Online Standards Actions & Public Review Drafts

Education industry facility managers, energy conservation workgroups, sustainability officers, electric shop foreman, electricians and front-line maintenance professionals who change lighting fixtures, maintain environmental air systems are encouraged to participate directly in the ASHRAE consensus standard development process.

“In 1970, Stanford professor Paul Ehrlich published a famous book, The Population Bomb, in which he described a disastrous future for humanity: 

‘The battle to feed all of humanity is over. In the 1970s and 1980s hundreds of millions of people will starve to death in spite of any crash programs embarked upon now.’

That prediction turned out to be very wrong, and in this interview American Enterprise Institute scholar Nicholas Eberstadt tells how we are in fact heading toward the opposite problem: not enough people. For decades now, many countries have been unable to sustain a #population replacement birth rate, including in Western Europe, South Korea, Japan, and, most ominously, China. The societal and social impacts of this phenomenon are vast. We discuss those with Eberstadt as well as some strategies to avoid them.”

Out take [35:22]:

“…All right this gets us right to the heart of of your essay and of the matter quoting you yet again the single best predictor for National fertility rates happens to be wanted family size as reported by women now you note there are polls that ask women how many children they’d like and you know that this doesn’t correlate perfectly with birth rates but it’s the best indicator in one sense this is a reassuring even heartening finding it highlights the agency at the very heart of our Humanity…

[“You’re talking about free will there people choosing their family size but if we permit the non-material realm of life to figure into our inquiry we may conclude that proposals to revive the American birth rate through subsidies vastly underestimate the challenge the challenge May ultimately prove to be civilizational in nature”] 

okay so I look at first of all that hits like a two by four — civilizational in nature — and on the one hand I think to myself wait a minute aren’t we all supposed to be delighted that in this modern world women are in a position to participate in the workforce they’re in a position to choose more carefully more explicitly more intentionally the number of children they’d like to have aren’t we supposed to believe that that’s a wonderful thing and that releasing that many women to the workforce should increase the dynamism and growth of our [economy]…and all that…good, good, good…”
