Its purpose is to make the homes of low-income clients more energy efficient, thereby reducing the households’ energy bills. The program also improves the health and safety of low-income homes. The energy efficiency and health and safety work is done using the most advanced technologies and testing protocols available in the housing industry. States administer the program in accordance with DOE rules and regulations.
