Chapter 11 of the IRC regulates what aspect of building design and construction?

Chapter 11 of the IRC (International Residential Code) specifically focuses on energy efficiency in residential buildings. This chapter sets forth requirements designed to reduce energy consumption and promote sustainable construction practices, essential for reducing the environmental impact of residential buildings. It provides guidelines on insulation, windows, HVAC systems, and lighting to ensure that homes are built and maintained to be as energy-efficient as possible.

This emphasis on energy efficiency is significant, as buildings account for a large portion of energy usage, and improving this facet of residential construction is critical for achieving broader energy conservation goals. By adhering to the stipulations in Chapter 11, builders and inspectors ensure that residences not only comply with current energy standards but also support initiatives for long-term sustainability and health of the environment.
