If you’re an engineer looking to specialize in smoke control systems, the journey can be both rewarding and challenging. Smoke control is a niche but critical aspect of fire protection engineering, and mastering it will open doors to exciting projects and career opportunities.
In this post, I’ll outline a recommended self-study plan based on the resources I’ve personally used to build my roots in smoke control systems. The study plan is designed to take about a year, depending on your pace, and focuses on applying knowledge to real-world projects as you progress.
This self-study plan is ideal for engineers aiming to specialize in smoke control and focuses solely on this discipline within fire protection and life safety. If you choose to expand into other areas of fire protection later, there are additional resources you can explore.
Action Step #1: Read the Major Smoke Control Codes and Standards
Start by reading NFPA 92, the most critical standard for smoke control systems, as you would a book. This will provide a comprehensive overview of its structure, objectives, and key requirements. Familiarizing yourself with the layout and organization of NFPA 92 will give you a mental framework, making it easier to find specific information as you work on various projects. Given its importance, you should spend the most time with this standard, as it forms the foundation for understanding and designing effective smoke control systems.
Afterward, you can apply the same approach to the other codes and standards listed in the table below to build a deeper understanding and broader perspective of smoke control systems.
I recommend investing in an NFPA Link subscription to access all NFPA standards and advanced search tools – as well as an ICC Digital Codes premium subscription to access valuable commentary. Or you can use the free viewer options from both of those websites.

Action Step #2: Purchase and Study the ASHRAE Handbook of Smoke Control Engineering
Invest in the ASHRAE Handbook of Smoke Control Engineering and read it thoroughly, cover to cover, multiple times. This handbook is structured like a university course curriculum and is designed to serve as your primary teacher in gaining a deep understanding of smoke control systems. Take detailed notes, use tools like mind maps and flashcards to reinforce key concepts, and aim to build a comprehensive grasp of the material.
In my opinion, this is the single most beneficial publication for mastering smoke control systems. I recommend purchasing a hard copy for study purposes, as physical books tend to aid in memory and retention better than digital formats. Later, you can also buy the PDF version for easy reference during active projects.
You should spend considerable time with this book—it will be your companion and go-to resource throughout your career, providing guidance when faced with new challenges or when you need a refresher (until a newer edition is published).
Action Step #3: Purchase and Study the SFPE and NFPA Handbooks
For a deeper theoretical understanding of fire dynamics and smoke control, purchase and study the SFPE Handbook of Fire Protection Engineering (5th Edition) and the NFPA Fire Protection Handbook (20th Edition). These handbooks provide valuable insights into the science behind fire behavior and life safety systems. While the chapter numbers may differ in the new 21st edition of the NFPA Fire Protection Handbook, either version will serve as an excellent resource. These comprehensive references will help solidify your knowledge and can be consulted regularly as you work on more advanced smoke control projects.
You should focus on the following chapters related to the fundamentals of fire and life safety that are most important in smoke control engineering.

Action Step #4: Purchase and Study the SFPE Books Related to Performance Based Design
To further enhance your expertise in smoke control, purchase and study two important Society of Fire Protection Engineers (SFPE) books related to performance-based design.
- SFPE Engineering Guide to Performance-Based Fire Protection (2nd Ed) provides a framework for designing fire protection systems, including smoke control, based on performance objectives rather than prescriptive codes. This is crucial for customizing smoke control strategies to fit unique building designs.
- 2018 SFPE Guide to Human Behavior in Fire focuses on how occupants react during fire emergencies, which is essential for designing smoke control systems that ensure safe egress. Understanding human behavior helps you design systems that allow for effective evacuation while keeping smoke conditions tenable.
Action Step #5: Learn How to Use Smoke Control Computational Software
Before diving into smoke control software, it’s crucial to first master the fundamentals of smoke control systems as outlined in the previous action steps. Many engineers make the mistake of jumping into learning the various smoke control computational software before fully understanding the principles behind the calculations, leading to improper usage, incorrect assumptions, and wasted time. Without a solid grasp of smoke control concepts—such as design objectives, performance criteria, and system requirements—you risk using the software ineffectively. Once you’ve covered the basics through the previous steps, you can confidently incorporate computational tools to enhance your designs.
Here are the top three software programs used in smoke control:
- CONTAM (or Thunderhead’s Ventus)
- CONTAM is used for analyzing airflow and contaminant transport in multi-zone buildings. It is particularly useful for performing airflow network models used to evaluate the design of pressurization smoke control systems such as stairwell pressurization, elevator pressurization, and zoned smoke control in complex buildings. Ventus, Thunderhead’s new software, offers an updated interface that uses CONTAM as the calculator. This tool is particularly useful for pressurization systems and helps ensure your design maintains safe air movement in case of fire.
- ASHRAE Handbook of Smoke Control Engineering has a full chapter dedicated to CONTAM training.
- The Thunderhead website also offers a free training course on Ventus.

- PyroSim (FDS Interface)
- PyroSim is a powerful user interface for the Fire Dynamics Simulator (FDS), commonly used for computational fluid dynamics (CFD) modeling of smoke and fire behavior. This software allows you to simulate the movement of smoke and heat within buildings, helping you optimize smoke control systems in complex spaces such as atriums or high-rise structures. PyroSim’s visual outputs also help in communicating your design approach to stakeholders.
- The Thunderhead website offers a free training course on Pyrosim.

- Pathfinder
- Pathfinder is a tool used for egress modeling, helping to simulate how occupants evacuate during a fire event. This software is essential for assessing whether your smoke control systems provide enough time for safe evacuation by analyzing how long it takes for people to move through smoke-affected areas. Combining Pathfinder with smoke modeling tools like PyroSim gives a complete picture of a smoke control system’s effectiveness.

By first building a strong foundation in smoke control fundamentals, you’ll be able to use these powerful software tools to their full potential, ensuring accurate, efficient designs that meet both safety and performance goals.
Action Step #6: Apply Your Book Knowledge to Real-World Projects and Collaborate with Other Professionals
While book knowledge is essential for understanding smoke control systems, it only becomes truly valuable when applied to real-world projects. Gaining hands-on experience will allow you to see how theoretical concepts perform in practical situations, helping you refine your skills and adapt to the complexities of real-life scenarios. Collaborating with other professionals—whether mechanical engineers, architects, installing contractors, or commissioning agents—enriches your learning by exposing you to different perspectives and expertise.
To apply your knowledge, start by reviewing past or ongoing projects and looking for opportunities to integrate the principles you’ve learned. Join project teams where smoke control design is a key component, and don’t hesitate to ask senior engineers for feedback on your designs. Take part in testing, inspections, and commissioning processes to see how systems work in practice, and always compare the outcomes with the theoretical models you’ve studied. This will build your confidence and enable you to better predict system performance in future projects.
