As part of a class assignment, Trine University mechanical engineering majors were tasked with designing a 1/12-scale model home designed to maintain an internal temperature between 74 and 80 degrees using only passive solar heating and the design of the home. Other factors considered included cost and weight. A lamp with four 1,000-watt bulbs was used to simulate sunlight to test the designs. As part of the project, students in the class toured Cardinal Glass Industries in Fremont, Indiana, which donated glass for students to use in their model homes. Joshua Cerda of Fayette was part of the group that had the best design for the competition.
