This tool is a self-constructing
intelligent graph. It will illustrate the various conditions of
moist air. Moist air is a mixture of dry air and water vapour.
The conditions of moist air include temperature, relative humidity,
dewpoint, density and many others. This tool can be used in many ways.
For example (see below), it can be used to determine the dewpoint or
condensation temperature of the indoor or outdoor air. Or, it can
be used to determine the temperature index (Ti) of a window and many
other building exposure conditions.
