Energy3D presents an easy-to-use 3D user interface for designing and analyzing model green buildings. Students can quickly sketch up a house, a building, or even a village. They can then evaluate solar heating of their structures using a virtual helidon to dynamically generate solar irradiation heat maps on any given day. Energy3D also allows students to print out a design, cut out the pieces, and use them to assemble a physical model. Energy3D is developed for children of age 6-18 and can be used in math, engineering, or physical science classes.
