“A Dance to the Music of Time” 1640 Nicolas Poussin
“The voice of the intellect is a soft one,
but it does not rest until it has gained a hearing.”
— Sigmund Freud
The education industry provides a large market for occupancy classes — athletic stadiums, student assembly spaces, performance theaters, large lecture halls– that depend upon effective audio systems*. To an unexpected degree the structural engineering, specification of materials and electrical system design and operation is informed by acoustical considerations. So does the integration of fire safety and mass notification systems into normal state enterprises so it is wise to follow and, ideally, participate in leading practice discovery and promulgation of audio standards.
The Audio Engineering Society — one of the first names in this space — has a due process platform that welcomes public participation. All of its standards open for public comment completed their revision cycle mid-November as can be seen on its standards development landing page below:
Note that AES permits access to those revision even after the comment deadline. You are encouraged to communicate directly with the Direct communication with the standards staff at Audio Engineering Society International Headquarters, 551 Fifth Avenue, Suite 1225, New York NY 10176, Tel: +1 212 661 8528
We keep the AES suite on the standing agenda of our periodic Lively Arts teleconference. See our CALENDAR for the next online meeting.
This facility class is one of most complex occupancy classes in education facilities industry so we also collaborate with experts active in the IEEE Education & Healthcare Facilities Committee. Much of the AES suite references, and borrows from, International Electrotechnical Commission system integration and interoperability standards. The IEEE E&H committee meets online again four times monthly in European and American time zones. The meeting dates are available on the IEEE E&H website

*Mass notification systems are governed by NFPA 72 and, while life safety wiring is separate from other wiring, the management of these systems involve coordination between workgroups with different business objectives and training.
In our collaboration with the IEEE Education & Healthcare Facilities Committee we are sensitive to the point of view of our research and standards setting colleagues in other nations; among them CEN (European Committee for Standardization) and CENELEC (European Committee for Electrotechnical Standardization) are two standardization organizations in Europe, and they have some similarities and differences.
CEN develops standards for a wide range of products, services, and processes, including construction, consumer goods, food and agriculture, and many others.
CENELEC, on the other hand, focuses specifically on electrotechnical standards, including electrical equipment, electronic components, and telecommunications.
Another key difference between CEN and CENELEC is their membership. CEN has members from 34 European countries, including national standardization bodies, industry associations, and consumer organizations. CENELEC has members from 34 European countries as well, but they are limited to national electrotechnical committees, which are responsible for electrotechnical standardization in their respective countries.
Despite their differences, both CEN and CENELEC play important roles in the development and promotion of European standards, and their standards are widely recognized and used across Europe and beyond. Its leadership committees meet this week in Brussels. CLICK HERE to access videolinks.
We had the pleasure to welcome the new CENELEC President Elect Mr Riccardo Lama at our offices, for a moment to engage with the CEN and CENELEC senior management team and the CEN and CENELEC Presidents Mr Stefano Calzolari and Mr Wolfgang Niedziella.@CEInorme@IECStandardspic.twitter.com/ynk9ViWb60
Safety and sustainability for any facility begins with an understanding of who shall occupy the built environment and what they will be doing in it. Since we are guiding young people toward their goal of building things that are useful and beautiful we select the International Building Code as a starting point for an occupancy that requires a more elevated concern for safety than a typical classroom.
For the purpose of formulating our own proposals we begin with the developmental transcripts of the previous code cycle. Recommended search terms: “Section 307”, “Studio”, “Classroom” “University” will give you a sample of the ideas in play. The complete monograph is linked below:

Technical Committee 64 develops the International Electrotechnical Commission consensus product that covers similar territory for the global electrical power industry as NFPA 70 (National Electrical Code). Keep in mind that the safety traditions of the NFPA suite of consensus products are inspired by fire safety considerations. IEC 60363 Electrical installations and protection against electric shock — the parent document that applies to the wiring systems of education and healthcare facilities — was inspired from voltage safety.
– concerning protection against electric shock arising from equipment, from installations and from systems without limit of voltage,
– for the design, erection foreseeable correct use and verification of all kind of electrical installations at supply voltage up to 1 kV a.c or 1,5 kV d.c., except those installations covered by the following IEC committees: TC 9, TC 18, TC 44, TC 97, TC99
– in co-ordination with TC 99, concerning requirements additional to those of TC 99 for the design, erection and verification of electrical installations of buildings above 1kV up to 35kV.
The object of the standards shall be:
– to lay down requirements for installation and co-ordination of electrical equipment
– to lay down basic safety requirements for protection against electric shock for use by technical committees
– to lay down safety requirements for protection against other hazards arising from the use of electricity
– to give general guidance to IEC member countries that may have need of such requirements
– and to facilitate international exchanges that may be hampered by differences in national regulations.
The standards will not cover individual items of electrical equipment other than their selection for use. Safety Pilot Function: Protection against electric shock.
Since neither the USNA National Committee to the IEC (USNA/IEC), nor the US Technical Advisory Administrator (National Electrical Manufacturers Association) has a workspace set up for responding to IEC 60364 calls for public comment, we set one up for ourselves several years ago for education facility and electrical engineering faculty and students:
Note that anyone in the world is welcomed to comment upon IEC documents, contingent upon obtaining (free) login credentials. To review the the strike-and-bold you will need login credentials. Alternatively, you may click in to the 4-times monthly teleconferences of the IEEE Education & Healthcare Facilities Committee. See our CALENDAR for the next online meeting.

The Illumination Engineering Societyis one of the first names in standards-setting organizations with a catalog routinely referenced in design guidelines and construction projects. Because of the money flow into illumination technologies worldwide the IES occupies a domain that is relatively crowded:
National Electrical Manufacturers and Medical Imaging Association; whose interest lies in leveling the playing field for about 300 electrical equipment manufacturers
Institute for Electrical and Electronic Engineers; whose interest lies in the research activity in seeing sciences, the luminescence sources and the power chain
American Society of Heating and Refrigeration Engineers; whose interest lies in energy conservation
National Fire Protection Association; whose interest lies in fire safety of lighting systems within building premises.
International Code Council; whose interest lies in pulling together all of the relevant standards for lighting egress paths of the built environment
International Electrotechnical Commission; whose interest lies in the administration of global electrical and electronic technologies
International Commission on Illumination; the international authority on light, illumination, colour, and colour spaces
There are others. With illumination power requirement on a downward trajectory where footcandles can be driven at information & communication technology voltage and current levels; we find relatively new entrants into the market with deep pockets and for good reason. In a typical building, the interior lighting load is the major electrical load (on the order of 40 percent) and a major contributor to the functionality of the building. There are a number of other trade associations that are participants in research and open source standards for faster moving parts of the illumination science. We will cover these in future, related posts.
Last year a new standardization project was launched by the IES. From the project prospectus:
IES LP-2-201x, Designing Quality Lighting for People in Outdoor Environments (new standard)
Project Need: This document is not intended to supersede existing IES application RPs, rather it will link the various documents together, augmenting them in subject areas not otherwise covered, including but not limited to sidewalks, bikepaths, pedestrian paths, parks, outdoor malls, pedestrian-only business districts, plazas, amphitheaters, large outdoor gathering areas, campuses, pedestrian bridges, and pedestrian underpasses.
Stakeholders: Lighting practitioners, electrical engineers, civic planners, civil engineers, architects, community-based planning groups, general public. Lighting recommendations for non-vehicular pedestrian applications using recommendations beyond illuminance only, which ultimately fails to provide a complete guideline for the visual experience of pedestrian-based tasks. The RP will be a comprehensive approach for light levels, glare, adaptation, spectrum, and contrast while addressing safety, timing, and perceived security. Application of these recommendations will ultimately enhance the pedestrian’s visual experience while also respecting the environment.
Soon to be released, a related product covering technical specifics of a familiar battleground — lighting controls:
The consultation closed May 24th and the agenda of the committee writing this standard is being administered. Very often technical committees are receptive to new ideas after a comment deadline if those ideas are submitted to a committee member directly. We invite anyone with an interest in this topic to click in to any of our daily colloquia to begin that process.
Not far into the future: individually controlled luminaires responsive to the use of campus pathways. There are already some pilot projects on higher education campuses.
A few other technical committees relevant to educational communities should be identified, though we will sort through the standards setting activity in separate posts:
We always encourage direct participation by space planners, workpoint experts and academic unit facility managers in IES standards development process. Contact: Patricia McGillicuddy, (917) 913-0027, [email protected]. 120 Wall Street, Floor 17, New York, NY.
We coordinate most of our electrotechnology standards advocacy with the IEEE Education & Healthcare Facilities Committee which meets 4 times monthly in European and American time zones. Its meeting agendas and login credentials are available on its website. Since illumination technologies are present in all spaces in education communities, IES consensus products will appear on the standing agenda of most disciplines. See our CALENDAR.
The Control of Noise at Work Regulations came into force for all industry sectors in Great Britain on 6 April 2006 (except for the music and entertainment sectors where they came into force on 6 April 2008). The aim of the Noise Regulations is to ensure that workers’ hearing is protected from excessive noise at their place of work, which could cause them to lose their hearing and/or to suffer from tinnitus (permanent ringing in the ears).
The level at which employers must provide hearing protection and hearing protection zones is 85 dB(A) (daily or weekly average exposure) and the level at which employers must assess the risk to workers’ health and provide them with information and training is 80 dB(A). There is also an exposure limit value of 87 dB(A), taking account of any reduction in exposure provided by hearing protection, above which workers must not be exposed.
