The minimum requirements for energy efficiency are found in which Chapter of the IRC?

The minimum requirements for energy efficiency in the International Residential Code (IRC) are outlined in Chapter 11. This chapter specifically addresses the building's energy performance, including insulation, air leakage, and the efficiency of various systems such as heating and cooling. It aims to establish guidelines that promote energy conservation and sustainability in residential construction.

The focus on energy efficiency in Chapter 11 is crucial because it helps set the baseline standards that must be met during the design and construction phases. This ensures residential buildings are not only safe and livable but also contribute positively to energy conservation goals.

Understanding the significance of Chapter 11 can help builders, inspectors, and homeowners ensure compliance with energy standards that can lead to reduced utility costs and a lower ecological footprint.
