Interior spaces intended for human occupancy must maintain a minimum temperature of how many degrees at 3 feet above floor level?

  1. 62 degrees

  2. 65 degrees

  3. 68 degrees

  4. 72 degrees

The correct answer is: 68 degrees

The minimum temperature requirement for interior spaces intended for human occupancy, specifically at a height of 3 feet above floor level, is established at 68 degrees Fahrenheit. This standard is set to ensure the comfort and health of occupants in various types of buildings. A temperature of 68 degrees is recognized as a reasonable baseline to maintain a comfortable environment, as it helps prevent issues related to excessive cold, which can lead to health problems or discomfort for those inside the space. It is also important in promoting adequate indoor air quality and preventing the growth of mold or other allergens that can thrive in cooler temperatures. This benchmark may vary depending on specific building codes or regulations within different jurisdictions, but the 68 degrees standard aligns with common practices aimed at safeguarding the well-being of occupants in residential and commercial settings.
