A process for determining the drying time for a structure or building uses energy values based on sensible and latent energy to determine the enthalpy evaporation evaluation value for a condition. The condition includes the ambient temperature, the dew point temperature, and the wet bulb temperature for the air. The condition also includes the ambient humidity ratio, the dew point humidity ratio, and the wet bulb humidity ratio. The process can be implemented in a device that uses these values to determine the enthalpy evaporation evaluation value, which is used to predict a drying time for the materials.

An apparatus for indirectly determining the dew point of compressed air at a particulate operating pressure including a capacitive sensor for measuring a relative humidity, a heating element for both heating and cooling a fraction of the compressed air, a controller for controlling the heating element based on a measured relative humidity, a temperature sensor for determining the temperature of the fraction. The controller is further configured to control the heating element such that the fraction is maintained at a predetermined constant relative humidity such that the dew point can be determined based on the temperature of the fraction.
