What percentage of time does the average American spend indoors?

  1. 50%

  2. 75%

  3. 85%

  4. 90%

The correct answer is: 90%

The average American spends around 90% of their time indoors, which includes activities in homes, workplaces, schools, and other indoor environments. This high percentage reflects the lifestyle and daily routines of most individuals, who engage in various activities such as work, school, and leisure predominantly within enclosed spaces. These statistics highlight the importance of indoor air quality and energy efficiency in buildings, as the majority of exposure to environmental factors occurs indoors. Understanding this concept is crucial for energy auditors, as it underscores the need for implementing effective strategies that enhance comfort, reduce energy consumption, and improve the overall indoor environment.
