Kitchen cooking ranks high as the causes of fire hazard in the built environment. ASHRAE 154 provides design criteria for the performance of commercial cooking ventilation systems.  Education communities have hundreds of food preparation enterprises in school districts, residence halls, hospitals and athletic venues. It is not intended to circumvent any safety, health or environmental requirement; however we find a fair amount of drama regarding the competing requirements of fire safety and sustainability among subject matter experts.  The stabilized version is dated 2022.

A noteworthy title in the ASHRAE standards catalog is ASHRAE 154 Ventilation for Commercial Cooking Operations.  Food preparation enterprises in school districts, residence halls, hospitals and athletic venues and central features in education communities.   Access to the 2022 edition is linked below:

FREE ACCESS ASHRAE 154

The purpose of ASHRAE 154 is to provide design criteria for the performance of commercial cooking ventilation systems.  It covers kitchen hoods, exhaust systems and replacement air systems,   It is not intended to circumvent any safety, health or environmental requirement; however we find a fair amount of drama between partisans of air movement controls and energy conservation interests.  Fire safety and the sustainability advocates are well funded voices.

There are no open consultations at the moment; but you may track release of any at the link below:

Public Review Draft Standards / Online Comment Database

Titles in the ASHRAE catalog move swiftly; many of them consultations lasting less than 45 days.

Interior environmental air safety is a concern that cuts across many professional disciplines.  Accordingly, we maintain this title on the standing agendas of several colloquia — Mechanical Engineering, Energy and Housing.  Starting 2022 we will break out this the subject of a separate, dedicated colloquium   See our CALENDAR for the next online meeting; open to everyone.

Research from the World Economic Forum has shown that improvements in the design and construction process can be achieved by using international standards like ICMS to gain comparable and consistent data. ICMS provides a high-level structure and format for classifying, defining, measuring, recording, analysing and presenting construction and other life-cycle costs.

Smart Cities: Wicked Problems

“Oxford from the River with Christ Church in the Foreground” | William Turner (1820)

 

Smart cities: moving beyond urban cybernetics to tackle wicked problems

Cambridge Journal of Regions, Economy and Society, Volume 8, Issue 1, March 2015 | “The Smart City”

 

Abstract. This article makes three related arguments. First, that although many definitions of the smart city have been proposed, corporate promoters say a smart city uses information technology to pursue efficient systems through real-time monitoring and control. Second, this definition is not new and equivalent to the idea of urban cybernetics debated in the 1970s. Third, drawing on a discussion of Rio de Janeiro’s Operations Center, I argue that viewing urban problems as wicked problems allows for more fundamental solutions than urban cybernetics, but requires local innovation and stakeholder participation. Therefore the last section describes institutions for municipal innovation and IT-enabled collaborative planning.

Standards Michigan Public Comment

Attention Is All You Need | Authors: Ashish Vaswani et al. (2017).  This groundbreaking paper introduced the Transformer architecture, replacing recurrent layers with self-attention mechanisms to enable parallelizable, efficient sequence modeling. It laid the foundational blueprint for all subsequent LLMs, revolutionizing natural language processing by capturing long-range dependencies without sequential processing.
BERT: Pre-training of Deep Bidirectional Transformers for Language Understanding | Authors: Jacob Devlin et al. (2018). BERT pioneered bidirectional pre-training via masked language modeling, allowing models to understand context from both directions. As an encoder-only Transformer, it achieved state-of-the-art results on 11 NLP tasks and established the pre-training/fine-tuning paradigm that underpins bidirectional LLMs like those in search and classification.
Training Compute-Optimal Large Language Models | Authors: Jordan Hoffmann et al. (2022).  Known as the Chinchilla paper, it revealed that optimal LLM performance requires balanced scaling of model size and data volume (e.g., 70B parameters trained on 1.4T tokens outperform larger models with less data). This shifted research toward data-efficient training, influencing efficient LLM development.

The University of Michigan has supported the voice of the United States education facility industry since 1993 — the second longest tenure of any voice in the United States.  That voice has survived several organizational changes but remains intact and will continue its Safer-Simpler-Lower Cost-Longer Lasting advocacy on Code Panel 3 in the 2029 Edition.

Today, during our customary “Open Door” teleconference we will examine the technical concepts under the purview of Code Panel 1; among them:

Article 206 Signaling Circuits

Article 300 General Requirements for Wiring Methods and Materials

Article 590 Temporary Installations

Chapter 7 Specific Conditions for Information Technology

Chapter 9 Conductor Properties Tables

Public Input on the 2029 Edition will be received until April 9, 2026.

Florence Nightengale: The Lady with the Lamp

Today we review the codes and standards that apply to the instructional and research facilities that support nursing science and practice.  There is no single organization with a best practice catalog as there are in other disciplines we follow.  Best practice is inspired by the inherited wisdom of practitioners, faculty and students who work alongside other members of healthcare provider teams.

“Kindergarten” c. 1885 | Johann Sperl

Safety and sustainability for any facility begins with an understanding of who shall occupy the built environment and how.  University settings, with mixed-use phenomenon arising spontaneously and temporarily, often present challenges.   Educational communities are a convergent settings for families; day care facilities among them.  First principles regarding occupancy classifications for day care facilities appear in Section 308 of the International Building Code, Institutional Group I; linked below:

2018 International Building Code Section 308 Institutional Group I-4 (Superseded in some jurisdictions)

The ICC Institutional Group I-4 classification includes buildings and structures occupied by more than five persons of any age who received custodial care for fewer than 24 hours per day by persons other than parents or guardian, relatives by blood, marriage or adoption, and in a place other than the home of the person cared far.  This group includes both adult and child day care.

We maintain focus on child day care.  Many educational communities operate child day care enterprises for both academic study and/or as auxiliary (university employee benefit) enterprises.

Each of the International Code Council code development groups fetch back to a shared understanding of the nature of the facility; character of its occupants and prospective usage patterns.

The 2024 revision of the International Building code is in production now.   Ahead of the formal, market release of the Group A tranche of titles you can sample the safety concepts in play during this revision with an examination of the documents linked below:

We encourage our safety and sustainability colleagues to participate directly in the ICC Code Development process.   We slice horizontally through the disciplinary silos (“incumbent verticals”) created by hundreds of consensus product developers every week and we can say, upon considerable authority that the ICC consensus product development environment is one of the best in the world.  Privately developed standards (for use by public agencies) is a far better way to discover and promulgate leading practice than originating technical specifics from legislative bodies.   CLICK HERE to get started.  Contact Kimberly Paarlberg (kpaarlberg@iccsafe.org) for more information.

There are competitor consensus products in this space — Chapter 18 Day-Care Occupancies in NFPA 5000 Building Construction and Safety Code, for example; a title we maintain the standing agenda of our Model Building Code teleconferences.   It is developed from a different pool of expertise under a different due process regime.   See our CALENDAR for the next online meeting; open to everyone.
