We could hasten agreement on technical solutions if partisans setting best practice standards could agree upon what we are talking about.  Then again, the meaning of This or That can only be understood in context.  All too frequently, when opposing partisans sense they are on the losing side of debate, they change the vocabulary or the fact set and we have to start all over again.

We gather our work on language standards over the past 30-odd years, starting with the definition of “Service Point” in the 1999 National Electrical Code and the 2002 National Electric Safety Code.  In recent years, engineers have been challenged by finding common agreement on what a “microgrid” is.  The dynamics of the struggle for competing stakeholders to agree on how to make educational settlements simpler, safer, lower-cost and longer-lasting is virtually identical to the struggle to agree on the meaning of modern English language in other domains.

The term “political correctness” was given currency when President George H.W. Bush explained the peril at the University of Michigan in 1992.  Its peril has only expanded since.

Abstract: Lighting systems with a big number of luminaires in large halls are a case of distributed loads that need topologies with modularity, whenever possible to ensure a uniform distribution of the supplying circuits, an easier installation, management, and maintenance. The light emitting diode (LED) luminaires give a great impact on the system operation due to their auxiliary series devices and to the high inrush currents of the ac-dc switching power supplies. This article proposes a topology to design LED lighting systems, configured in a modular scheme of a main ac distribution and a branch dc distribution supplying luminaires clusters. Each cluster is provided as a “double-dual corded” equipment with double power supply and double control type, digital, and analogic. The suggested topology aims to make available a system that allows overcoming fault situations by design and permits maintenance activities limiting and recovering degradation conditions. In this way, the lighting system of special locations, for which there is the willingness-to-accept greater financial costs against loss service risks, can satisfy the requirement of continuous availability system. To provide more details on the proposed design criteria this article describes, as case study, the lighting system of a parliamentary hall with one thousands of luminaires.

As apologists for active involvement in the US standards system we owe no blind allegiance any educational settlement or the domain occupied by vertical incumbers; rather, we mean that we are actively engaged in providing explanations, justifications for maintaining them as centers of civilization.

Heat Tracing

“Street in Røros in Winter” 1903 Harald Sohlberg

The National Electrical Contractors Association best practice catalog features a suite of titles (National Electrical Installation Standards to meet the intent of the National Electrical Code (NEC); particularly where the NEC asserts that an installation be constructed in a “neat and workmanlike manner”.   As anyone who has had to reckon with the subjectivity of the local electrical inspector knows, the determination of “neat and workmanlike” can be mighty subjective.   The NECA documents are used by construction owners, specifiers, contractors and electricians to clearly illustrate the performance and workmanship standards essential for different types of electrical construction.  Because the NEC is intended to be primarily a wiring safety standard, the NEIS suite is referenced throughout the National Electrical Code.  Electrical shop foremen and front line electricians take note.

NECA Standards and Publication Development Home Page

One of the NECA products that may be of interest to facility managers and risk management units in the education industry this time of year is NECA 202-2013 Standard for Installing and Maintaining Industrial Heat Tracing Systems.   About half of the United States deals with snow and ice half the year.

NECA 202 details procedures for the installation, testing, and documentation of electrical freeze protection and process heat tracing systems. Heat tracing cable types covered by this publication include: self-regulating, constant wattage, and zone heating cables and mineral insulated heating cables. 2 is approved as an American National Standard.   The 2013 edition is the current edition and will likely need revisiting/revision/reaffirmation as an American national standard soon.

The technical literature that keeps pipes breaking and roofs failing is complicated space. A common conundrum in the construction industry is which discipline (architectural, mechanical or electrical) should specify application of this technology; especially in value-engineering negotiations when each discipline is trying to reduce its unit costs. Control and communication system add another layer of complexity.  Several consensus standards occupy this technology; cross referencing one another and leaving gaps

ASCE 7-10 Snow Load Provisions

IEEE 515 Standard for the Testing, Design, Installation, and Maintenance of Electrical Resistance Trace Heating for Industrial Applications

UL 515 Standard for Electrical Resistance Trace Heating for Commercial Applications

IEC 62395 Electrical resistance trace heating systems for industrial and commercial applications

National Electrical Code Article 427

There are codes and standards developed by ASTM International, the International Code Council and ASHRAE International that set the standard of care for pipe insulation for energy conservation purposes but we will deal with the interdependence of standard of care set by those documents in a separate post.   Organizations such as FM Global typically derive their customer recommendations from consensus standards developers.

Because heat tracing is a cross-disciplinary technology we maintain it on the standing agenda of several colloquia: Power, Water, Bucolia, Snow & Ice and Mechanical   See our CALENDAR for the next meeting; open to everyone.  You may obtain an electronic copy of this standard from neis@necanet.org.  Communicate directly with Aga Golriz, (301) 215-4549, Aga.golriz@necanet.org.

Snow Management

“A Morning Snow–Hudson River” 1910 George Wesley Bellows | Smithsonian American Art Museum

This time of year in the Northern Hemisphere we keep an eye on snow management  standards; among them titles developed by the Accredited Snow Contractors Association.  The barriers to entry into this domain are relatively low and, arguably undisciplined; hence the need for standards setting.  Even when only partially adopted, use of ANSI accredited standards reduces the “wheel reinvention” that is common to the business side of the education industry when new initiatives, or continuous improvement programs are undertaken without consideration of already existing leading practice discovery by ANSI-accredited technical committees.  Start here:

ASCA Standards Home Page

The parent title for the emergent ASCA bibliography is System Requirements for Snow and Ice Management Services; free to ASCA members.  The current version is dated 2014 and will likely be updated and/or re-affirmed.  The circumstances of the pandemic has slowed the work of many standards setting committees.  The safety and sustainability concepts remain intact, however.  Among them:

  • If snow can be removed from a lot or hard surface and appropriate room exists, always push the snow as far back as possible beyond the curb or lot edge to make room for additional snow.
  • If snow cannot be removed from a lot or hard surface, always place snow piles on a predetermined spot approved by the client and marked on the snow contractor’s preseason site report.  
  • Do not pile snow in a handicap parking space.
  • Do not bury or plow snow onto a fire hydrant, post indicator valve, or fire hookup along the building wall.
  • Avoid placement of snow piles where thaw/melt off can run across the parking lot surface. Try to place piles near drain grates to avoid icy situations during thaw-and-refreeze periods.
  • Do not push snow against a building.
  • Do not block building doorways or emergency exits.
  • Do not block pedestrian walks or paths with snow piles.
  • Do not push snow onto motor vehicles.
  • Do not plow snow in front of or bury trash containers. Sidewalk labor must shovel inside trash container enclosure for access to the doors. If the container is not in an enclosure, create a clear path to the access doors or panels.

"Liberty, when it begins to take root, is a plant of rapid growth" - (Letter to James Madison, March 2, 1788)“The cold was our pride, the snow was our beauty.” — F. Scott Fitzgerald ('Wiinter Dreams' 1922)

ASCA has more recently released another title — Standard Practice for Procuring and Planning Snow & Ice Management Services — that seems (by its title alone) to be a companion consensus product.  From its prospectus:

This standard of practice covers essential procuring and planning for snow and ice management services. Standards for procuring and planning are essential for business continuity and to improve safety for patrons, tenants, employees, and others in the general public. Knowing how to describe service requirements in a snow and ice management request for proposal (RFP) is an important component to providing effective services, particularly where winter weather is a variable. This standard practice provides guidance on the snow and ice management procurement and planning process to aid in the creation of RFPs, contracts, agreements, and monitoring procedures. This standard will not be submitted for consideration as an ISO, IEC, or ISO/IEC JTC-1 standard.

Apart from these titles, we do not see any recent happening in the ASCA standards setting enterprise.  We will pass information along as it becomes available.  Alternatively, you may communicate directly with ASCA, 5811 Canal Road  Valley View, OH 44125, Ph: (800) 456-0707.  Most education communities employ a combination of permanent and contract staff for these services.

We maintain the ASCA bibliography on our Snow & Ice colloquia  See our CALENDAR for the next online meeting; open to everyone.
