Emerging Technologies: Using Microenvironments To Provide Individual Comfort

Thermal comfort, like politics, is truly local. Similarly, comfort clearly reflects personal preferences, which also makes it difficult to quantify. Research has statistically quantified comfort according to experimental surveys of people working under various conditions. According to studies of actual office buildings, ^1,2 a large portion of typical office occupants about 40 out of every 100 may be dissatisfied with their thermal work environment. Even a well-designed HVAC system leaves at least 10 out of every 100 occupants too hot or too cold.³ Microenvironment conditioning, also called taskambient conditioning, allows individuals to control the temperature in their personal space. This creates microzones with conditions tailored to the varying preferences of each occupant, presumably maximizing each persons comfort.
