This week, students received instruction on computer-aided design program ArchiCAD from ArchiCAD professional Rick Pernell and Ecosa faculty Tom Hahn. The program allows students to create 3-D models of their designs which can be used to produce perspective and elevation diagrams as well as sun and shade studies based on a site’s latitude. Students also practiced using a tool called a Suntracker to determine the amount of sun and shade available on a particular lot, taking into account potential blockages like trees, landforms and other structures.
