The most accurate results for developing an energy model come from conducting an operation test. This type of test evaluates the actual performance of a building's systems under real operating conditions, which provides a comprehensive understanding of how energy flows within the building during occupancy. It considers variables such as occupant behavior, internal heat gains, and ventilation rates that are crucial for an accurate energy model.

While envelope tests, interior pressure tests, and exterior pressure tests offer valuable insights into building envelope performance and air leakage, they do not account for the dynamic interactions of systems and occupancy. An operational test captures the real-world operational dynamics, leading to a well-informed energy model that reflects how the building will perform in actual use. As such, focusing on operation tests is essential for developers, engineers, and energy modelers aiming to achieve precision in their assessments.
