Fire Modeling

Fire modeling is the use of computer-based simulation tools to predict the behavior of fire, smoke, and heat in buildings or specific environments. It allows engineers to evaluate how fires develop, spread, and interact with building geometry, materials, and suppression systems. Modeling is crucial for performance-based design, where prescriptive codes may not fully address unique building features or emerging technologies.

Unlike full-scale fire testing, which physically recreates fire scenarios under controlled conditions, fire modeling uses mathematical equations and empirical data to simulate outcomes. While full-scale testing provides direct, observable results, it is often costly, time-consuming, and limited to specific setups. Fire modeling can efficiently analyze multiple scenarios, making it a practical alternative or complement when physical testing is impractical or unsafe.

Fire modeling can determine temperature profiles, smoke movement, tenability conditions, sprinkler activation times, and egress performance. These results inform design decisions, optimize suppression strategies, and support code equivalency or variance requests, ultimately improving life safety and system efficiency.
