In almost every building, owners or tenants have a need for some level of security or access control. The IBC covers a wide range of door locking and control techniques, but the shear number of sections and underlying requirements can be tough to digest. Many folks have trouble knowing which code sections apply, and even if the correct section is identified, it can be a challenge to understand the requirements.
In this post, I take a number of these door locking requirements and translate them into (hopefully) more clear and concise language. I also provide some general commentary on my experience in using each type of door/locking arrangement. References are provided to the last 4 editions of the IBC. All references within the article itself are to the most recent code edition. Click one of the door/lock types in table below to jump to that section.

This post is a continuation of the Proposed Code Change Series, where I highlight some of the interesting and controversial code changes that were presented at the 2024 ICC Committee Action Hearings (CAH). These proposed changes, which could become part of the 2027 ICC codes, are the first step of the updated ICC code development process that now includes two Committee Action Hearings (CAH1 and CAH2), as well as the Public Comment Hearing (PCH).

As the global push towards environmentally friendly solutions continues, the HVAC industry has been experiencing a shift in refrigerant technology. A2L refrigerants, categorized as "mildly flammable,” have been a hot conversation topic in the construction community. The push towards eliminating A1 refrigerants, which have a higher Global Warming Potential (GWP), has coincided with additional design requirements for A2L refrigerants that have been challenging for many architects and engineers.
In this article, we'll provide a detailed overview of A2L refrigerants, touching on everything from their fundamental characteristics to the critical code requirements surrounding their installation and use.

For years, architect clients have asked me for a code solution to solve the challenge of corridors that exceed the dead end limit. As a quick reference, dead ends are limited to 20 feet, except in Groups B, E, F, I-1, M, R-1, R-2, R-4, S and U with a full NFPA 13 sprinkler system, where the limit is increased to 50 feet (2021 IBC 1020.5).
One of the fundamental concepts of fire protection and life safety in a building is compartmentation - the division of a building into multiple compartments to limit the spread of fire and smoke. The provision of floor assemblies, and specifically fire-resistance rated floor assemblies, is one common example of compartmentation. At the same time, there are legitimate reasons to design openings through these floor separation, such as elevator hoistways. To simultaneously allow for elevator hoistways and maintain some level of compartmentation, the International Building Code (IBC) sets forth requirements for protection of hoistway openings. This post will provide an overview of hoistway opening protection, including when it is required and the various options for how to provide the protection. All code references are to the 2021 IBC.

Key Takeway: Stair pressurization is a method for providing a smokeproof enclosure. When used, it is considered a smoke control system and must be accompanied by a rational analysis. If you have ever worked on the design of a high-rise building, you almost certainly have come across a stairway pressurization system. Fans located on the roof, a shaft next to the stair, extra ductwork – all are common in high-rise design. But even though nearly all high-rise buildings have these systems, there are many wide-spread misconceptions and misunderstanding about stair pressurization. For example, did you know that stairway pressurization is not actually required by the IBC? What?!? Or did you know that there is a detailed analysis that must be conducted as part of the stair pressurization design process? In this article, we will dispel some of these common misconceptions and misunderstandings about stair pressurization systems. Key Takeaway: An FPEDE report is a detailed analysis of fire protection and life safety requirements. It is required for certain projects in Prince George's County and Rockville, MD. If you are working on a project in Prince George's County, MD or in Rockville, MD, you may have had a last minute scare on a project, where you learned that a Fire Protection Engineering Design Evaluation Report (FPEDE) was required. In this article, we'll discuss what and FPEDE is, when it is required, and how you can obtain one for your project. If you already know you need an FPEDE for your project, our friends at Campbell Code Consulting can help you. Click here to contact them directly. |
