AIA members understand the tremendous potential of Building Performance Simulation tools to address some of the key challenges facing the building industry in the 21st century by improving design and operation. Making the most of this potential requires us to adequately prepare users to effectively apply tools with full knowledge of their applicability, modelling limitations, and default methods and data and provide them with the skill set to scrutinise their results. In this webinar, we'll explore the importance of teaching the fundamentals of how BPS tools model physical processes, the impact of modelling choices, and the significance of input data, including hidden defaults.
