suggested  systems used in a pavilion , performance-related criteria, as energy use, occupant comfort, daylighting, and acoustics. It 
is important to note that PBD is an approach to building design that uses iterative analysis to 
inform decisions, supporting optimum occupant experience, lowered resource use, and 
minimal negative environmental impact. PBD is an approach that works to meaningfully 
inform building design in a way that can impact everything from energy consumption and 
operating costs to occupant comfort and environmental impact, and it is used from 
schematics and conceptual design through to the construction phase. This holistic approach 
is what PBD is all about, and it can empower the architect in ways that were previously not 
possible.
