Ventilation for Commercial Cooking Operations

“Dutch Kitchen” / Artist Unknown

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.

Doors have long since been a simple “opening” or “fenestration”.   Doors are “portals”; nodes on the geometry of the Internet of Small Things.  There are 100’s of thousands of these nodes on any single college, university or school district.  First costs run from $1000 per door in a classroom to $100,000 per door in hospitals with maintenance and operation costs commensurate with complexity of the hardware and software needed to maintain integration of the door with building security and energy systems.

We find the bulk of best practice identified in the catalogs of the following accredited standards developers for the United States construction markets:

American National Standards Institute

American Society of Mechanical Engineers

ASHRAE International

ASTM International

Conflicting Requirements of Exit Doors

Standard Practice for Installation of Exterior Windows, Doors and Skylights

Standard Consumer Safety Specification for Child Safety Locks and Latches for Use with Cabinet Doors and Drawers

Repair Methods for Common Water Leaks at Operable Windows and Sliding Glass Doors

Building Industry Consulting Service International (BICSI)

Builders Hardware Manufacturers Association

International Code Council

Institute of Electrical and Electronic Engineers

National Fire Protection Association

Steel Door Institute

The US federal government and all 50-states adapt safety and sustainability concepts from the foregoing publishers; either partially or whole cloth.

Today we examine the moment in the standard of care for doors in education communities in the United States.   Join the colloquium with the login credentials at the upper right of our home page.

Recognizing signs and doors for Indoor Wayfinding for Blind and Visually Impaired Persons

Mouna Afif, et al

 

Abstract:  Indoor signage plays an essential component to find destination for blind and visually impaired people. In this paper, we propose an indoor signage and doors detection system in order to help blind and partially sighted persons accessing unfamiliar indoor environments. Our indoor signage and doors recognizer is builded based on deep learning algorithms. We developed an indoor signage detection system especially used for detecting four types of signage: exit, wc, disabled exit and confidence zone. Experiment results demonstrates the effectiveness and the high precision of the proposed recognition system. We obtained 99.8% as a recognition rate.

Gone are the days when a door was just a door (or “opening”) — at least insofar as public safety expectations are  concerned.   As we explain in our School Security Standards post the pace of standardization in public safety management and technology has increased; driven by events.  Some of the risk management can be accomplished with integrated electrotechnology solutions that are complex and more expensive to design, build, operate and maintain.  Architects, electrical and information and communications technology professionals usually have to collaborate on the application of the technology owing to the blistering pace of cross-disciplinary integration.

The Builders Hardware Manufacturers Association (BHMI) is an ANSI accredited consensus standards developer for building access and egress technology standards that facility managers may see incorporated by reference deep in the architectural and electrical sections of construction contract specifications.    An example of how BHMA standards show up in enforceable contracts can be found in most master construction contracts in the education facility industry.*on Page 38 Master Construction Contract

The front door to the BHMA public commenting facility is linked below:

BHMA Standards Home Page

No drafts have been released for public consultation at this time; however we maintain the BHMA catalog on our daily scan of building construction standards.

We always encourage direct participation in the BHMA standards development process by facility managers and those with oversight on campus security.  You may obtain an electronic copies of any of the foregoing from MTierney@kellencompany.com and send comments to the same (with copy to psa@ansi.org).

All education facility security standards can be discussed any day at our daily 11 AM Eastern time teleconference.  We also set aside one hour every month to review the status of the rapidly evolving “fabric” of school security standards.  See our CALENDAR for the next online meeting; always using the same login credentials and always open to everyone.

* See Page 38: Master Construction Specifications (Samples) (E.729) : Note the requirement to “Use date of standard in effect as of Bid date”.  Standards  in this space are moving quickly, and integrate with other electrotechnology standards.   It is an uphill battle for architects, engineers, specifiers and contractors to keep pace with them.  Compliance authorities usually keep pace with them, however, because the compliance interest is very strong in all standards development committees and compliance revenue originates from enforcing them.
