The ASHRAE recommended minimal thermal standard for dwellings is _________ degrees F at 40% humidity and an air circulation rate of 20 fpm.

• A. 72
• B. 74
• C. 76
• D. 78

Answer: (C)

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) provides guidelines for maintaining acceptable indoor thermal conditions, ensuring comfort and health in residential spaces. The recommended minimal thermal standard for dwellings is set at 76 degrees Fahrenheit when the relative humidity is at 40% and the air circulation rate is 20 feet per minute. This standard is based on extensive research into human comfort, which considers temperature, humidity, and air movement as essential factors. At 76 degrees Fahrenheit in conjunction with 40% humidity and adequate air circulation, occupants are likely to feel comfortable, which in turn may promote health and well-being. Understanding this guideline is crucial for professionals involved in housing sanitation and safety, as it helps in designing and evaluating living spaces to ensure they are conducive to the residents' comfort and health.
