The Performance Path to Energy Code Compliance

Using a performance path instead of the prescriptive table in the International Energy Conservation Code (IECC) can provide significant cost-savings for builders. Performance paths are more flexible and account for the energy performance of an entire home, rather than the one-size-fits-all approach used by prescriptive tables.

This publication is designed for: builders, designers, contractors, architects

This publication explains the difference between a prescriptive path and a performance path and the cost-savings benefits of using a performance path to meet IECC requirements. It also provides a table that can help builders and energy designers understand the relative energy efficiency impacts of common home assemblies and systems.

Key sections include:

• Paths to compliance in the IECC

• Energy Rating Index

• Performance path trade-off options and their estimated energy use impacts

• Meeting energy and structural requirements with continuous wood panel sheathing
