Property Loss Prevention

Left Panel Of George Julian Zolnay’s Allegorical “Academic, Business & Manual Education” Granite Frieze At Francis L. Cardozo High School (Washington, DC)

All fifty United States have their own “signature” disaster with which to reckon; some more than others.   California has earthquakes, Florida has hurricanes, Missouri has floods; and so on,  Life and property loss are preventable; but losses will persist because technical solutions notwithstanding, culture determines human behavior.  It is impossible to be alive and safe.

FM Global is one of several organizations that curate privately developed consensus products that set the standard of care for many industries; education communities among them.  These standards contribute to the reduction in the risk of property loss due to fire, weather conditions, and failure of electrical or mechanical equipment.  They incorporate nearly 200 years of property loss experience, research and engineering results, as well as input from consensus standards committees, equipment manufacturers and others.

If you want FMGlobal as your insurance carrier, or to supplement your organization’s self-insurance program, then you will likely be assigned an FMGlobal conformity professional.

A scan of its list data sheets indicate a number of noteworthy updates of documents establishing minimum requirements for safety technologies common in education facilities:

To respond to calls for public consultation you will need to set up (free) access credentials.

We keep FMGlobal titles — and the literature of other property insurers involved in standards setting — on the standing agenda of our Risk, Snow and Prometheus colloquia.  See our CALENDAR for the next meeting.

Global Positioning System: A Generation of Service to the World

Citizens of the Earth depend upon United States leadership in this technology for several reasons:

Development: The GPS was originally developed by the US Department of Defense for military purposes, but it was later made available for civilian use. The US has invested heavily in the development and maintenance of the system, which has contributed to its leadership in this area.

Coverage: The GPS provides global coverage, with 24 satellites orbiting the earth and transmitting signals that can be received by GPS receivers anywhere in the world. This level of coverage is unmatched by any other global navigation system.

Accuracy: The US has worked to continually improve the accuracy of the GPS, with current accuracy levels estimated at around 10 meters for civilian users and even higher accuracy for military users.

Innovation: The US has continued to innovate and expand the capabilities of the GPS over time, with newer versions of the system including features such as higher accuracy, improved anti-jamming capabilities, and the ability to operate in more challenging environments such as indoors or in urban canyons.

Collaboration: The US has collaborated with other countries to expand the reach and capabilities of the GPS, such as through the development of compatible navigation systems like the European Union’s Galileo system and Japan’s QZSS system.

United States leadership in the GPS has been driven by a combination of investment, innovation, collaboration, and a commitment to improving the accuracy and capabilities of the system over time.

Baseball Lighting

The College World Series begins this weekend in Omaha between Louisiana State University and Coastal Carolina.

 

Baseball is a pastoral game and lighting changed the experience of it. Since a baseball is less than 3-inches in diameter and routinely travels 400 feet at 100 miles per hour, illumination design must have outfielders in mind as well as other players and spectators.

“Baseball at Night” | Morris Kantor (1934)

 

 

 

“Baseball is ninety percent mental

and the other half is physical.”

– Yogi Berra

 

After athletic facility life safety obligations are met (governed legally by NFPA 70, NFPA 101, NFPA 110,  the International Building Code and possibly other state adaptations of those consensus documents incorporated by reference into public safety law) business objective standards may come into play.  For business purposes, the documents distributed by the National Collegiate Athletic Association inform the standard of care for individual athletic arenas so that swiftly moving media production companies have some consistency in power sources and illumination as they move from site to site.  Sometimes concepts to meet both life safety and business objectives merge.

 

During the spring baseball season the document linked below provides guidance for illumination designers, contractors and facility managers:

NCAA Best Lighting Practices

Athletic programs are a significant source of revenue and form a large part of the foundation of the brand identity of most educational institutions in the United States.   We focus primarily upon the technology standards that govern the safety, performance and sustainability of these enterprises.  We cover the objectives of the energy conservation advocates in separate posts; notably advocates using the International Code Council and the ASHRAE suite to advance their agenda to press boxes and the entire baseball experience (interior and exterior) site in separate posts.

We collaborate very closely with the IEEE Education & Healthcare Facilities Committee where subject matter experts in electrical power systems meet 4 times each month in the Americas and Europe.

See our CALENDAR for our next Sport colloquium  We typically walk through the safety and sustainability concepts in play; identify commenting opportunities; and find user-interest “champions” on the technical committees who have a similar goal in lowering #TotalCostofOwnership.

Rightsizing Electrical Power Systems

Standards Michigan, spun-off in 2016 from the original University of Michigan Business & Finance Operation, has peppered NFPA 70 technical committees writing the 2016-2026 National Electric Code with proposals to reduce the size of building premise feeder infrastructure; accommodating the improvements made in illumination and rotating machinery energy conservation since the 1980’s (variable frequency drives, LED lighting, controls, etc.)

These proposals are routinely voted down in 12-20 member committees representing manufacturers (primarily) though local inspection authorities are complicit in overbuilding electric services because they “bill by the service panel ampere rating”.  In other words, when a municipality can charge a higher inspection fee for a 1200 ampere panel, what incentive is there to support changes to the NEC that takes that inspection fee down to 400 amperes?

The energy conservation that would result from the acceptance of our proposals into the NEC are related to the following: reduced step down transformer sizes, reduced wire and conduit sizes, reduced panelboard sizes, reduced electric room cooling systems — including the HVAC cooling systems and the ceiling plenum sheet metal carrying the waste heat away.   Up to 20 percent energy savings is in play here and all the experts around the table know it.   So much for the economic footprint of the largest non-residential building construction market in the United States — about $120 billion annually.

The market incumbents are complicit in ignoring energy conservation opportunity.  To paraphrase one of Mike Anthony’s colleagues representing electrical equipment manufacturers:

“You’re right Mike, but I am getting paid to vote against you.”

NFPA Electrical Division knows it, too.

Rightsizing Commercial Electrical Power Systems: Review of a New Exception in NEC Section 220.12

Michael A. AnthonyJames R. Harvey

University of Michigan, Ann Arbor

Thomas L. Harman

University of Houston, Clear Lake, Texas

For decades, application of National Electrical Code (NEC) rules for sizing services, feeders and branch circuits has resulted in unused capacity in almost all occupancy classes. US Department of Energy data compiled in 1999 indicates average load on building transformers between 10 and 25 percent. More recent data gathered by the educational facilities industry has verified this claim. Recognizing that aggressive energy codes are driving energy consumption lower, and that larger than necessary transformers create larger than necessary flash hazard, the 2014 NEC will provide an exception in Section 220.12 that will permit designers to reduce transformer kVA ratings and all related components of the power delivery system. This is a conservative, incremental step in the direction of reduced load density that is limited to lighting systems. More study of feeder and branch circuit loading is necessary to inform discussion about circuit design methods in future revisions of the NEC.

Classroom Acoustics

“Quiet people have the loudest minds.”
— Stephen Hawking

Donegan Acoustics

With acoustic considerations a substantial contributor to the effectiveness of learning spaces — classrooms, lecture hall, performance arts and athletic venues, etc.  — we follow action in the Acoustical Society of America (ASA) suite of ANSI-accredited standards.

ASA Standards Homepage

For example, building codes in the United States identify horizontal and vertical acoustic insulation between floors and between walls, respectively, as design considerations.   Section 1206.2 of the International Building Code deal with  horizontal and vertical wall sealant applications for “airborne sound” mitigation, for example.   Fire protection and mass notification systems identified in NFPA 72 and UL 2572 depend upon alarms actually being heard by the occupants underscore the importance of acoustic design.  When lively art spaces are also instructional spaces we seek to understand the standard of care for acoustic design of classroom spaces.   Of particular interest to us in the ASA bibliography is the title linked below:

ASA S12.60 Acoustical Performance Criteria, Design Requirements, and Guidelines for Schools, Part 2: Relocatable Classroom Factors.

This is a fairly stable standard; though other sound related technologies we cover in other sound related technologies (ISO TC/43 Acoustics and IEC Electroacoustics TC 29).  Last year’s update was required by ANSI and we had no comments to submit; absent queries from students, faculty and staff.  It is wise to keep it on our radar, however, given the step-change in education communities owed to the pandemic.

On your own you may communicate with Caryn Mennigke at ASA: (631) 390-0215, asastds@acousticalsociety.org.  The ASA uses ANSI Standards Action for issuing live public consultation notices.

Since acoustic technologies cut across many disciplines we maintain it on the standing agenda of our Construction, Lively Art and Nota Bene teleconferences.   See our CALENDAR next scheduled meeting; open to everyone.

Study on the Relationship Between Speech Intelligibility and Quality Estimates in University Classrooms

Arkadiy Prodeus, et al

Abstract: In this paper, correlation coefficients between the five objective estimates of speech quality, on the one hand, and the Speech Transmission Index as speech intelligibility measure, on the other hand, were estimated. This comparison was performed using binaural room impulse responses corresponded to different points of the three university auditoriums of different sizes. Speech quality was assessed using intrusive speech quality measures: Segmental Signal-to-Noise Ratio, Logarithmic Spectral Distortion, Frequency-Weighted Segmental Signal-to-Noise Ratio, Bark Spectral Distortion, and Perceptual Evaluation of Speech Quality. The formation of signals distorted by reverberation was performed by convolving of pure signals with binaural room impulse responses of the premises. A high level of correlation (0.6-0.99) of Bark Spectral Distortion estimates with estimates of the Speech Transmission Index for rooms of different sizes was revealed. Correlation of estimates (0.65-0.98) of Frequency-Weighted Segmental Signal-to-Noise ratio with Speech Transmission Index estimates was observed for medium and large rooms. Significant correlation (0.96-0.99) of Perceptual Evaluation of Speech Quality with Speech Transmission Index estimates was observed only for large audiences. At the same time, estimates of the Segmental Signal-to-Noise Ratio and Logarithmic Spectral Distortion turned out to be practically uncorrelated with Speech Transmission Index estimates for all studied premises.

Campus Outdoor Lighting

“The Starry Night” | Vincent van Gogh

The IEEE Education & Healthcare Facilities Committee has completed a chapter on recommended practice for designing, building, operating and maintaining campus exterior lighting systems in the forthcoming IEEE 3001.9 Recommended Practice for the Design of Power Systems for Supplying Commercial and Industrial Lighting Systems; a new IEEE Standards Association title inspired by, and derived from, the legacy “IEEE Red Book“.  The entire IEEE Color Book suite is in the process of being replaced by the IEEE 3000 Standards Collection™  which offers faster-moving and more scaleable, guidance to campus power system designers.

Campus exterior lighting systems generally run in the 100 to 10,000 fixture range and are, arguably, the most visible characteristic of public safety infrastructure.   Some major research universities have exterior lighting systems that are larger and more complex than cooperative and municipal power company lighting systems which are regulated by public service commissions.

While there has been considerable expertise in developing illumination concepts by the National Electrical Manufacturers Association, Illumination Engineering Society, the American Society of Heating and Refrigeration Engineers, the International Electrotechnical Commission and the International Commission on Illumination, none of them contribute to leading practice discovery for the actual power chain for these large scale systems on a college campus.   The standard of care has been borrowed, somewhat anecdotally, from public utility community lighting system practice.  These concepts need to be revisited as the emergent #SmartCampus takes shape.

Electrical power professionals who service the education and university-affiliated healthcare facility industry should communicate directly with Mike Anthony (maanthon@umich.edu) or Jim Harvey (jharvey@umich.edu).  This project is also on the standing agenda of the IEEE E&H committee which meets online 4 times monthly — every other Tuesday — in European and American time zones.  Login credentials are available on its draft agenda page.
