True or False: The insulation recommendations made by the U.S. DOE have been generally increased and exceed building code requirements.

The statement is true because the insulation recommendations made by the U.S. Department of Energy (DOE) focus on optimizing energy efficiency in residential buildings. Over the years, the U.S. DOE has updated its guidelines to reflect advancements in energy conservation practices and the need for better thermal performance in homes. These recommendations typically aim for higher insulation R-values than those stipulated in the minimum building code requirements, reflecting a trend towards enhanced energy efficiency.

By encouraging additional insulation beyond what is required by building codes, the DOE aims to reduce energy consumption, lower heating and cooling costs, and improve overall comfort within homes. This trend underscores a proactive approach to building performance and sustainability, making the recommendation valid and consistent with energy conservation goals.
