In the ever-evolving landscape of building design and operation, the pursuit of energy efficiency and occupant comfort stands at the forefront. Transient system simulation emerged as a powerful tool to achieve these objectives, providing a comprehensive understanding of the dynamic interactions between building systems and indoor climate conditions.

Delving into the Fundamentals of Transient System Simulation

Transient system simulation is a computational technique that enables the analysis of building systems over time. It involves the use of mathematical models to represent the physical components and processes within a building, such as heating, ventilation, and air conditioning (HVAC) systems, thermal mass, and occupant behavior. These models are then solved numerically to predict the dynamic behavior of the building over a specified period, typically ranging from hours to years.
