ABSTRACT
The article presents an updated and more complete version of the cooling load design tools for underfloor air distribution(UFAD). It features the version 3.1 and the EnergyPlus, a publicly available whole building energy simulation program capable of modeling the more complex heat transfer processes. It mentions that the design tool predicts the room air temperature profile based on the fraction of the cooling load assigned to the room.
