Today we feature the catalog of the Illumination Engineering Society — one of the first names in standards-setting in illumination technology, globally* with particular interest in its leading title IES LP-1 | LIGHT + DESIGN Lighting Practice: Designing Quality Lighting for People and Buildings.
From its prospectus:
“…LIGHT + DESIGN was developed to introduce architects, lighting designers, design engineers, interior designers, and other lighting professionals to the principles of quality lighting design. These principles; related to visual performance, energy, and economics; and aesthetics; can be applied to a wide range of interior and exterior spaces to aid designers in providing high-quality lighting to their projects.
Stakeholders: Architects, interior designers, lighting practitioners, building owners/operators, engineers, the general public, luminaire manufacturers. This standard focuses on design principles and defines key technical terms and includes technical background to aid understanding for the designer as well as the client about the quality of the lighted environment. Quality lighting enhances our ability to see and interpret the world around us, supporting our sense of well-being, and improving our capability to communicate with each other….”

Illumination technologies run about 30 percent of the energy load in a building and require significant human resources at the workpoint — facility managers, shop foremen, front-line operations and maintenance personnel, design engineers and sustainability specialists. The IES has one of the easier platforms for user-interest participation:
IES Standards Open for Public Review
Because the number of electrotechnology standards run in the thousands and are in continual motion* we need an estimate of user-interest in any title before we formally request a redline because the cost of obtaining one in time to make meaningful contributions will run into hundreds of US dollars; apart from the cost of obtaining a current copy.
We maintain the IES catalog on the standing agendas of our Electrical, Illumination and Energy colloquia. Additionally, we collaborate with experts active in the IEEE Education & Healthcare Facilities Committee which meets online 4 times monthly in European and American time zones; all colloquia online and open to everyone.

Heat tracing is a process used to maintain or raise the temperature of pipes and vessels in order to prevent freezing, maintain process temperature, or ensure that products remain fluid and flow through the system properly.
Heat tracing works by using an electric heating cable or tape that is wrapped around the pipe or vessel, and then insulated to help retain the heat. The heating cable is connected to a power source and temperature control system that maintains the desired temperature by regulating the amount of heat output from the cable. Heat tracing is commonly used in industrial applications where temperature control is critical, such as in chemical plants, refineries, and oil and gas facilities.
There are several types of heat tracing, including electric heat tracing, steam tracing, and hot water tracing, each of which have their own unique advantages and disadvantages. The selection of the appropriate type of heat tracing depends on the specific application and the required temperature range, as well as factors such as cost, maintenance, and safety considerations.
Today we review the literature for snow and ice management (and enjoyment) produced by these standards-setting organizations:
Accredited Snow Contractors Association
American Society of Mechanical Engineers
Institute of Electrical & Electronic Engineers
Electrical Heat Tracing: International Harmonization — Now and in the Future
International Code Council
National Electrical Contractors Association

It is a surprisingly large domain with market-makers in every dimension of safety and sustainability; all of whom are bound by state and federal regulations. Join us at 16:00 UTC with the login credentials at the upper right of our home page.
There have been several recent innovations that have made it possible for construction activity to continue through cold winter months. Some of the most notable ones include:
Overall, these innovations have made it possible for construction crews to work through the winter months more comfortably and safely, which has helped to keep projects on schedule and minimize delays.

Abstract: In the past, electrical heat tracing has been thought of as a minor addition to plant utilities. Today, it is recognized as a critical subsystem to be monitored and controlled. A marriage between process, mechanical, and electrical engineers must take place to ensure that optimum economic results are produced. The Internet, expert systems, and falling costs of instrumentation will all contribute to more reliable control systems and improved monitoring systems. There is a harmonization between Europe and North America that should facilitate design and installation using common components. The future holds many opportunities to optimize the design.

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.

RESEARCHGATE: HEAT-TRACING OF PIPING SYSTEMS TYPES OF HEAT-TRACING SYSTEMS
Today our focus turns to outdoor electric deicing and snow melting wiring systems identified as suitable for the environment and installed in accordance with the manufacturer’s instructions. They work silently to keep snow load from caving in roofs and icicles falling from gutters onto pedestrian pathways.
While the voltage and ampere requirement of the product itself is a known characteristic, the characteristic 0f the wiring pathway — voltage, ampere, grounding, short circuit, disconnect and control — is relatively more complicated and worthy of our attention. Articles 426-427 of the National Electrical Code is the relevant part of the NEC
Free Access 2023 National Electrical Code
Insight into the ideas running through technical committee deliberations is provided by a review of Panel 17 transcripts:
2023 NEC Panel 17 Public Input Report (633 pages)
2023 NEC Panel 17 Public Comment Report (190 pages)
We hold Articles 427 in the middle of our priority ranking for the 2023 NEC. We find that the more difficult issues for this technology is the determination of which trade specifies these systems — architectural, electrical, or mechanical; covered in previous posts. Instead, most of our time will be spent getting IEEE consensus products in step with it, specifically ANSI/IEEE 515 and IEEE 844/CSA 293.
Technical committee work on the 2023 National Electrical Code was completed in October. Public input on the 2026 Edition will be received until 7 September 2023.
We collaborate with the IEEE Education & Healthcare Facility Committee which meets online 4 times per month in European and American time zones. Since a great deal of the technical basis for the NEC originates with the IEEE we will also collaborate with IEEE Standards Coordinating Committee 18 whose members are charged by the IEEE Standards Association to coordinate NFPA and IEEE consensus products.
