These models are made by NMSEA member Ben Luce. They represent a common solar home design found throughout New Mexico. Note the Sun and Earth Globes: These are used in conjunction with the model to demonstrate the principles of passive solar design.
Ben makes these model homes out of form core, clear plastic (for the windows), and quarter round (used as reinforcement inside). A template created by Ben is used, so that making more models is easy. The roofs are removable (they are fastened with Velcro strips), so that the dark floor can be viewed.
