TL;DR
The performance code path is the compliance route in which a design is approved by demonstrating it achieves the code's intended outcome — through engineering analysis, energy modeling, or testing — instead of following the prescriptive tables line by line. Energy codes formalize it: an IECC simulated-performance or ERI analysis can trade more glass against a tighter envelope or better equipment.
What it means
The performance code path is the compliance route in which a design is approved by demonstrating it achieves the code's intended outcome — through engineering analysis, energy modeling, or testing — instead of following the prescriptive tables line by line. Energy codes formalize it: an IECC simulated-performance or ERI analysis can trade more glass against a tighter envelope or better equipment. It buys design freedom at the cost of modeling fees and documentation the plan reviewer must accept.
