Which of the following strategies can contribute to optimal thermal comfort for building occupants?

Scheduling regular HVAC system maintenance is the best answer because properly maintained systems are more likely to deliver stable temperatures, humidity control, ventilation, and air movement. LEED Indoor Environmental Quality addresses thermal comfort because occupant satisfaction and productivity are affected by air temperature, radiant temperature, air speed, humidity, clothing, and activity level. Maintenance helps ensure that thermostats, dampers, sensors, filters, coils, and controls function as designed. Ceiling fans only in common areas may improve air movement in limited spaces, but they do not provide building-wide thermal comfort. Large open spaces alone do not guarantee comfort and may create uneven conditions. Removing individual controls is incorrect because occupant control is a valuable LEED strategy for improving comfort and satisfaction.
