I want to model a cubic room with walls faced north, west, south, and east. The room dimension is 5x5x2.7 m. with a window fully covered the north wall. I have no additional software such as sketch up, open studio, or etc. I entered all data by hand to idf editor After hundreds times of trying I was successful to receive output from the energy plus but still the room surfaces have not edge on another surface. Can somebody help me what are vertices and starting coordinates for each of surfaces? Thank you.
