Because of GARD’s experience with both the DOE-2 and EnergyPlus building energy analysis programs, PNNL requested that GARD provide services to convert a DOE-2 model of a 20,000 sq. ft. office building to EnergyPlus format. This prototype office building was originally developed as part of a U.S. Dept. of Energy project for Development of the Advanced Energy Design Guide for Small Office Buildings.
