Lyndon B. Johnson: Remarks Upon Signing the Higher Education Facilities Act
Builders Hardware Manufacturer Association Standards Catalog
ARCHIVE: April 6, 2019
The Builders Hardware Manufacturers Association (BHMA) is an ANSI accredited standards developing organization for building access and egress technology that education industry real asset managers find referenced deep in the architectural and electrical sections of construction contract specifications (as in “Conform to all applicable standards”). Architects, electrical, fire protection and information and communications technology professionals usually have to collaborate on the design, construction. operations and maintenance of fenestration technologies.
Gone are the days when a door was just a door (or “opening” or “fenestration”). Doors are now portals; an easily identifiable control point in the Internet of Things electrotechnical transformation. There are 100’s of thousands of them on large research university campus; for example. 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 technical solutions that are complex and more expensive to design, build, operate and maintain.
A fair estimate of the annualized cost of a door now runs on the order of $1000 to $10,000 per door (with hospital doors at the high end).
BHMA develops and maintains performance standards for locks, closers, exit devices and other builders hardware. It has more than 40 ANSI/BHMA standards. The widely known ANSI/BHMA A156 series of standards describes and establishes features and criteria for an array of builders hardware products including locks, closers, exit devices, butts, hinges, power-operated doors and access control products. They are listed on the link below:
BHMA has opened one of its standards for public review that is relevant to our contribution to the security and sustainability agenda of the education facility industry; an agenda that necessarily involves a growing constellation of interacting specifics
BHMA A156.4 Standard for Door Controls – Closers. This Standard contains requirements for door closers surface mounted, concealed in the door, overhead concealed, and concealed in the floor. Also included are pivots for floor closers. Criteria for conformance include cycle, operational, closing force, and finish tests.
Given that BHMA consensus products are largely product standards (much the same way UL Standards are product standards) it is wise to keep an eye on a related installation standards found in the fenestration sections of model building and fire safety codes and in ASTM E2112 Standard Practice for Installation of Exterior Windows, Doors and Skylights.
Comments are due May 6th. 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).
The BHMA suite is on the standing agenda of our monthly Construction Specification and Design Guideline teleconference; an informal session that should interest building contractors and design professionals who prepare documents that use the general purpose clause: “Conform to all applicable standards”. That usually means the latest standard. 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:

The NFPA 99 Healthcare Facilities Code committee develops a distinct consensus document (i.e. “regulatory product”) that is distinct from National Electrical Code Article 517; though there are overlaps and gaps that are the natural consequence of changing technology and regulations. It is worthwhile reviewing the scope of each committee:
NFPA 99 Scope: This Committee shall have primary responsibility for documents that contain criteria for safeguarding patients and health care personnel in the delivery of health care services within health care facilities: a) from fire, explosion, electrical, and related hazards resulting either from the use of anesthetic agents, medical gas equipment, electrical apparatus, and high frequency electricity, or from internal or external incidents that disrupt normal patient care; b) from fire and explosion hazards; c) in connection with the use of hyperbaric and hypobaric facilities for medical purposes; d) through performance, maintenance and testing criteria for electrical systems, both normal and essential; and e) through performance, maintenance and testing, and installation criteria: (1) for vacuum systems for medical or surgical purposes, and (2) for medical gas systems; and f) through performance, maintenance and testing of plumbing, heating, cooling , and ventilating in health care facilities.
NFPA 70 Article 517 Scope: The provisions of this article shall apply to electrical construction and installation criteria in healthcare facilities that provide services to human beings. The requirements in Parts II and III not only apply to single-function buildings but are also intended to be individually applied to their respective forms of occupancy within a multi-function building (e.g. a doctor’s examining room located within a limited care facility would be required to meet the provisions of 517.10) Informational Note: For information concerning performance, maintenance, and testing criteria, refer to the appropriate health care facilities documents.
In short, NFPA 70 Article 517 is intended to focus only on electrical safety issues though electrotechnology complexity and integration in healthcare settings (security, telecommunications, wireless medical devices, fire safety, environmental air control, etc.) usually results in conceptual overlap with other regulatory products such as NFPA 101 (Life Safety Code) and the International Building Code.













Several issues were recently debated by the Article 517 technical committee during the 2023 National Electrical Code Second Draft meetings
There are, of course, many others, not the least of which involves emergency management. For over 20 years our concern has been for the interdependency of water and electrical power supply to university hospitals given that many of them are part of district energy systems.
We need to “touch” this code at least once a month because of its interdependence on other consensus products by other standards developing organizations. To do this we refer NFPA 99 standards action to the IEEE Education & Healthcare Facilities Committee which meets online four times monthly in European and American time zones.

Minimum Design Loads and Associated Criteria for Buildings and Other Structures
Updated: September 13
(Original Post: April 12, 2021)
During today’s colloquium we will review all of the concepts tracking in the Group A tranche relevant to student housing facilities owned by the college, university or school district; soon to be discussed during the Committee Action Hearings starting September 22nd. There are quite a few so we will likely not have time to cover best practice titles for off-campus housing; a sensitive area. We will set a separate colloquium for this topic in early 2022.
Group A Committee Action Hearings begin September 22nd and we will provide a link to the ICC livestream every day.

During today’s colloquium on fire safety we will review all of the concepts tracking in the Group A tranche; soon to be discussed during the Committee Action Hearings starting September 22nd.
July 12th
For today’s colloquium on elevators and lifts we will review the following concepts tracking in the Group A tranche:
IBC § 1109.2.1| E30-21, E31-21, et. al | The intent of this proposal(s) is to allow for ramps to serve as an accessible route off an occupied roof instead of requiring standby power on the elevator for that occupied roof.
IBC § 1109.2.1| E30-21, E31-21, et. al | Related to the above. Parking garages and self-service storage facilities have extremely low occupancy loads. Increasing the 4-story limit to 6-
stories for when standby power for elevators is required takes this practical difference in uses into account.
IBC § 1109.2.2| E34-21, et. al | Providing the fire department the option for using the elevator for assisted evacuation in any elevator building using fire department recall; with the additional
improvements of standby power (1009.4.1) at five stories and the fire service access elevator protections at 120 feet.
IBC § 1010.2.15 | E56-21 | Elevator lobby exit access doors
IBC § 1010.2. | E56-21 | Elevator lobby exit access doors
IBC § 3006.3 | G184-21 | Elevator hoistway pressure
IBC § 3001.2 | G175-21 | Elevator communication systems
IBC § 1020.2.1 | G182-21 | Elevator hoistway fire protection
IBC § 3007.6 | G187-21 | Elevator corridors and access
Keep in mind that most of these failed as stand-alone proposals but will likely inform decisions on related proposals; at least administratively.

Much has changed in the ICC code development process–not the least of which is the absence of the Livecast. Today we will examine our own proposals regarding, a) a performance-based electrical design of building interior feeder power chains; b) market-making by incumbents enlivened by the protected class of money that flows into student accommodations on and off campus.
Operational Resilience of Hospital Power Systems in the Digital Age
Abstract: An advanced guideline is required to support the design of power supply systems for the performances of service continuity and power outage resilience, which are vital for hospital power systems and strategic operational structures (SOSs). The supply sources, the power system topology, and its management are fundamental in guaranteeing the electrical resilience of the power system. There is still no standard to evaluate the adequacy of hospital power systems for natural calamities and human-made disasters and, subsequently, for the ordinary operation. The World Health Organization recognizes it as a basic problem and at this aim has to claim clearly the status of SOSs for the hospitals, recommending to safeguard and plan the full operability. The hospital power systems need a local fortified electrical structure, designed for service continuity during fault events and managed to ensure an adequate dynamic response to any emergency and maintenance needs. The importance of the business continuity management is highlighted; it has to be qualified for a permanent design with both the in-op approaches for the initial installation of the system and its life cycle operation.

Supporting swimming pools with electricity involves various essential functions such as filtration, heating, lighting, and sanitation. Ensuring safety and energy efficiency is crucial, and pool owners can take steps to minimize electricity costs and environmental impact. Key points:
Filtration and Circulation: Swimming pools rely on electric pumps to circulate water through filters, removing debris and maintaining water quality.
Heating: Electric heaters or heat pumps are used to regulate water temperature for comfort, especially in colder seasons.
Lighting: Underwater and pool area lighting enhance safety and aesthetics, typically powered by electricity.
Chlorination and Sanitation: Electric chlorinators or ozone generators help maintain water cleanliness and hygiene.
Automation: Electric control systems enable pool owners to manage filtration, heating, and lighting remotely for convenience and energy efficiency.
Energy Efficiency: Pool owners can invest in energy-efficient equipment, like variable-speed pumps and LED lighting, to reduce electricity consumption and operating costs.
Operations and Maintenance: Regular electrical maintenance ensures safe and reliable pool operation, preventing electrical faults and hazards. The electricity cost for pool operation can be significant, so pool owners should consider energy-efficient practices and equipment to reduce expenses.
Education communities present one of the largest installed bases of artificially created bodies of water; the most abundance resource on earth. These bodies vary in size, purpose, and design but are all created by human intervention to serve specific needs, whether practical, recreational, or aesthetic. Safe and sustainable management of them in the Unite States are informed by best practice found in Article 680 of the National Electrical Code with scope statement below:
Construction and installation of electrical wiring for, and equipment in or adjacent to, all swimming, wading, therapeutic, and decorative pools; fountains; hot tubs; spas; and hydromassage bathtubs, whether permanently installed or storable, and to metallic auxiliary equipment, such as pumps, filters, and similar equipment.
Consultation on the First Draft of the 2026 revision closes August 24, 2024.
