Improved Thermal Comfort

Thermal comfort is the state of your body temperature feeling comfortable, that is you do not feel too hot or too cold in your home. There are 6 primary and 5 secondary factors that impact on how your body temperature feels.  They are:

Primary Factors

1. Metabolic Rate

2. Clothing Insulation

3. Air Temperature

4. Humidity

5. Air movement/ventilation

6. Heat from sun’s rays

Secondary Factors

1. Age

2. Gender

3. Adaptability to changing weather conditions

4. Climate you were born in

5. The climate zone you now live in

Research conducted  by Kansas State University and in cooperation with the Technical University of Denmark led to an understanding of how you and your household members perceive thermal comfort, resulting in the development of a seven-point scale that can apply to rate your feeling of thermal comfort.

By properly insulating and draught-proofing your home, you can maximize thermal comfort and create an ideal environment for all household members. Insulation will help regulate temperature, humidity and radiant heat, while draught-proofing will effectively control air movement or ventilation. With the right measures in place, you can easily turn an uncomfortable home into a comfortable one.

Predicted Mean Vote * Rating Scale of Thermal Comfort

his is a thermal sensation index known as the Predicted Mean Vote (PMV) arising from the research conducted.  This scale provides you and your household members with a way to rate your level of comfort, taking into account each person’s unique response to heat and cold which is based on the temperature of the skin and the primary and secondary factors.
