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 Standards Home Page

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.

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.

Design of a gateway for ubiquitous classroom

Smart classroom: Gateway for ubiquitous classroom

Hichem Bargaoui & Rawia Bdiwi

In educational environment, the use of new pedagogies such as collaborative learning requires an evolution from a traditional classroom model to active classroom. The students should be able to share resources to collaborate with each other through computers, tablets, or other devices. The design of smart classroom should enable the control of audiovisual equipments, projectors, interactive whiteboards, in order to facilitate interaction among teachers and students. Ubiquitous computing or pervasive computing is a concept where processors and sensors are embedded in various physical objects to form a network and communicate information. Applying the pervasive computing can facilitate the collaborative learning by creating a smart learning environment. The ubiquitous classroom should be able to support interaction of heterogeneous devices connected through wireless links to a gateway. This paper presents a model of classroom that makes several smart devices such as laptops, tablets, projectors connected through a gateway in order to encourage communication of information between learners and the smart environment. Also, the gateway manages classroom smart devices by automatic detection and connectivity and it serves as application execution platform. Finally the gateway allows the classroom to be remote managed as well as the remote integration of application.
