Energy3D is a computer-aided engineering tool for students to design, analyze, and construct model green buildings. Students can quickly sketch up a building and then evaluate its energy performance for any given day and location. Based on computational building physics, Energy3D can generate time graphs (resembling data loggers) and heat maps (resembling infrared images) for in-depth analyses. Energy3D also allows students to print out a design, cut out the pieces, and use them to assemble a physical model. Energy3D has been developed for children of age 6-18 and can be used in math, engineering, or physical science classes.
