Metrology is the scientific discipline that deals with measurement, including both the theoretical and practical aspects of measurement. It is a broad field that encompasses many different areas, including length, mass, time, temperature, and electrical and optical measurements. The goal of metrology is to establish a system of measurement that is accurate, reliable, and consistent. This involves the development of standards and calibration methods that enable precise and traceable measurements to be made.
The International System of Units is the most widely used system of units today and is based on a set of seven base units, which are defined in terms of physical constants or other fundamental quantities. Another important aspect of metrology is the development and use of measurement instruments and techniques. These instruments and techniques must be designed to minimize errors and uncertainties in measurements, and they must be calibrated against recognized standards to ensure accuracy and traceability.
Metrology also involves the development of statistical methods for analyzing and interpreting measurement data. These methods are used to quantify the uncertainty associated with measurement results and to determine the reliability of those results.
This year’s Annual Fashion Show features 171 looks from 42 designers. Collections and single-submission garments were chosen by a panel of industry critics and jurors. The pieces include evening wear, market-ready, universal design and more. https://t.co/3shpSI9LdV
The School of Fashion had the pleasure of hosting students from Streetsboro Middle School. Students got the chance to gain a better understanding of fashion, design and knitwear by participating in a variety of educational activities.
“What art is, in reality, is this missing link, not the links which exist.
It’s not what you see that is art; art is the gap”
— Marcel Duchamp
Today we refresh our understanding of the literature that guides the safety and sustainability goals of lively art and special event setting on the #WiseCampus. Consortia have evolved quickly in recent years, leading and lagging changes in the content creation and delivery domain. With this evolution a professional discipline has emerged that requires training and certification in the electrotechnologies that contribute to “event safety”; among them:
ASHRAE International
Standard 62.1: This standard establishes minimum ventilation rates and indoor air quality requirements for commercial buildings, including theaters and auditoriums.
Standard 55: This standard specifies thermal comfort conditions for occupants in indoor environments, which can have an impact on air quality.
RP-16-17 Lighting for Theatrical Productions: This standard provides guidance on the design and implementation of lighting systems for theatrical productions. It includes information on the use of color, light direction, and light intensity to create different moods and effects.
RP-30-15 Recommended Practice for the Design of Theatres and Auditoriums: This standard provides guidance on the design of theaters and auditoriums, including lighting systems. It covers topics such as seating layout, stage design, and acoustics, as well as lighting design considerations.
DG-24-19 Design Guide for Color and Illumination: This guide provides information on the use of color in lighting design, including color temperature, color rendering, and color mixing. It is relevant to theater lighting design as well as other applications.
Dance and Athletic Floor Product Standards: ASTM F2118, EN 14904, DIN 18032-2
Incumbent standards-setting organizations such as ASHRAE, ASTM, ICC, IEEE, NFPA have also discovered, integrated and promulgated event safety and sustainability concepts into their catalog of best practice titles; many already incorporated by reference into public safety law. We explore relevant research on crowd management and spectator safety.
The circumstances of the pandemic has made “re-rationalization” of education community spaces an urgent priority. Today at 15:00 UTC we pick through the concepts in play. Use the login credentials at the upper right of our home page.

Safety and sustainability for any facility begins with an understanding of who shall occupy it. University settings, with mixed-use phenomenon arising spontaneously and temporarily, present challenges and no less so in square-footage identified as performing arts facilities. Education communities present the largest installed base of mixed use and performing arts facilities. A distinction is made between supervised occupants that are in secondary schools (generally under age 18) and unsupervised occupants that are in university facilities (generally above age 18).
First principles regarding occupancy classifications for performing arts facilities appear in Section 303 of the International Building Code Assembly Group A-1. The public edition of the 2021 IBC is linked below:
Each of the International Code Council code development groups A, B and C; fetch back to these classifications. You can sample the safety concepts in play with an examination of the document linked below:
Each of the foregoing documents are lengthy so we recommend using search terms such as “school”, “college”, ‘”university”, “auditorium”, “theater”, “children”, “student” to hasten your cut through it.
We find continuation of lowering of the lighting power densities as noteworthy. Technical committees assembled and managed by the International Code Council, the American Society of Heating & Refrigeration Engineers and the Illumination Engineering Society are leaders in developing consensus products that drive the LED illumination transformation.
The revision schedule for the next tranche of ICC titles that are built upon the foundation of the IBC is linked below:
We encourage experts in education communities — facility managers, research and teaching staff, architectural and engineering students — to participate directly in the ICC Code Development process at the link below:
Colleagues: Mike Anthony, Jim Harvey, Richard Robben
The International Code Council (ICC) develops its codes and standards through a consensus-driven process. The ICC Code Development Process follows these major stages:
Code Change Proposal Submission
Stakeholders (e.g., government officials, industry professionals, and the public) submit proposals to modify existing codes or introduce new provisions.
Committee Action Hearing (CAH)
Expert committees review and evaluate submitted proposals.
Public testimony is allowed, and committees vote on whether to approve, disapprove, or modify the proposals.
Public Comment Period
After the CAH, the public can submit comments or suggest modifications to the committee’s decisions.
These comments help refine the proposed changes before final voting.
Public Comment Hearing (PCH)
ICC members discuss and vote on public comments.
This step ensures that all voices are heard and debated before finalizing changes.
Online Governmental Consensus Vote (OGCV)
Governmental members vote on the final code changes electronically.
Only governmental voting members (e.g., code officials) participate in this stage to ensure the process remains unbiased.
Publication of New Code Edition
Approved code changes are incorporated into the next edition of the ICC codes.
The ICC updates its codes every three years (e.g., 2021, 2024, 2027 editions).
This structured process ensures that ICC codes remain comprehensive, up-to-date, and responsive to industry needs while maintaining safety and functionality.

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.
There are five key components needed to address in each construction contract as a protection against litigation in an industry that is rich in possibilities.
Scope of the project. …
Total cost and payment requirements. …
Project timeline. …
Lien law protection. …
Dispute resolution.
Today at the usual hour we examine a few representative contracts:
The cost of compliance with general conditions in a typical construction project can vary widely depending on factors like project size, complexity, location, and specific requirements. General conditions refer to the indirect costs that support the project—things like project management, temporary facilities, safety measures, and administrative expenses—not the direct costs of labor, materials, or equipment tied to physical construction.
In percentage terms, general conditions typically account for 5% to 15% of the total project cost, with most projects falling in the 5% to 10% range for standard residential or commercial builds. Smaller projects might see percentages closer to or exceeding 10% because fixed costs (like a site trailer or a project manager’s time) don’t scale down as much as direct costs. Larger, more complex projects—like industrial or infrastructure work—might trend toward the lower end (5% or less) since direct costs dominate, diluting the relative impact of general conditions. For example, a $300,000 residential project might allocate $15,000 to $30,000 (5% to 10%) for general conditions, while a $10 million commercial project could see $500,000 or less (5%) if efficiencies kick in.
The highest level of standardization for the building interiors on the emergent #SmartCampus originates in ISO TC 205 — Building Environment Design. This committee is charged with standards setting in the design of new buildings and retrofit of existing buildings for acceptable indoor environment and practicable energy conservation and efficiency. Building environment design addresses the technical building systems and related architectural aspects, and includes the related design processes, design methods, design outcomes, and design-phase building commissioning. Indoor environment includes air quality, and thermal, acoustic, and visual factors. The business plan is linked below:
Some of the key ideas in the scope of this project are listed below:
– the design of energy-efficient buildings
– building control systems design
– indoor air quality
– indoor thermal environment
– indoor acoustical environment
– indoor visual environment
– radiant heating and cooling systems
– heating and cooling systems
– building commissioning planning
– moisture in buildings
We see many of the foregoing ideas in the catalog of ASHRAE International — ANSI’s US Technical Advisory Group Administrator in this project, as well as a number of others (CLICK HERE). There are 31 Participating member and 28 Observing member nations.
Generally speaking, ISO consensus products are performance standards and contrast sharply with prescriptive standards in the energy-related domains in the United States. Prescriptive standards are easy to enforce but difficult to write. Performance standards are easy to write but difficult to enforce.
Facility managers that oversee building automation units in education communities in the United States are encouraged to participate in the development of ISO 205 by communicating directly with Brian Cox at ASHRAE ([email protected]). We keep all ISO standards on the standing agenda of our periodic Global and AEdificare standards colloquia. We also maintain this committee’s catalog on the standing agenda of our Mechanical colloquium. See our CALENDAR for the next online meetings; open to everyone.
The Eurocodes are ten European standards (EN; harmonised technical rules) specifying how structural design should be conducted within the European Union. These were developed by the European Committee for Standardization upon the request of the European Commission. The purpose of the Eurocodes is to provide:
A means to prove compliance with the requirements for mechanical strength and stability and safety in case of fire established by European Union law.[2]
A basis for construction and engineering contract specifications.
A framework for creating harmonized technical specifications for building products (CE mark).
Since March 2010 the Eurocodes are mandatory for the specification of European public works and are intended to become the de facto standard for the private sector. The Eurocodes therefore replace the existing national building codes published by national standard bodies, although many countries have had a period of co-existence. Additionally, each country is expected to issue a National Annex to the Eurocodes which will need referencing for a particular country (e.g. The UK National Annex). At present, take-up of Eurocodes is slow on private sector projects and existing national codes are still widely used by engineers.
Eurocodes appear routinely on the standing agendas of several of our daily colloquia, among them the AEDificare, Elevator & Lift and Hello World! colloquia. See our CALENDAR for the next online meeting; open to everyone.
