Heat transfer is the process of thermal exchange between different systems. Generally there will be a net heat transfer from a hotter system to a cooler system.

Very broadly, the mechanisms of heat transfer can be described as:

For more information see: Heat transfer.

Aspects of the thermal environment that can affect heat transfer by these mechanisms include:

There are a number of measures that can be used to approximate the total affect of these aspects at a single point. For more information see: Temperature.

The experience people have of the thermal environment that surrounds them will also be affected by personal factors such as:

This is a personal experience that cannot be accurately measured, but it may be represented approximately by standards such as Predicted Mean Vote (PMV) and Percentage People Dissatisfied (PPD).

For more information see: Thermal comfort.
