“The Department of Energy’s ‘EnergyPlus’ computer simulation program will assist homebuilders and designers dramatically lower energy use in buildings,” said Abraham.

Features of the software include realistic system controls, moisture adsorption and desorption in building elements, interzone airflow, low-temperature radiant heating-cooling, interior surface convection, thermal comfort modeling options, evaporative cooler models, steam absorption chiller, and flat-plate exhaust-air heat recovery options.

It also lets users calculate the impacts of different hvac systems with various types of lighting and window treatments.
