The PowerPod is a modular home that incorporates many green design elements, including a solar butterfly roof that collects rainwater and includes an active solar array for electricity and hot water. Designed by Lawrence, Massachusetts based PowerHouse Enterprises, the PowerPod can be transported on two trailers to your site for assembly. Measuring just 480 square feet, the floor plan highlights an open living/dining/kitchen area that opens onto a front porch. High ceiling create a sense of spaciousness. A PowerPod home costs about $100,000 or $200 per square foot.
The company also makes another larger modular home. A key design element of this green building is its metal roof, which on first thought may not seem energy-efficient. After all, metal absorbs heat, and air conditioners consume a lot of electricity.
But PowerHouse’s metal roof serves two specific purposes: heating the house in the cold season and generating electricity. Builders run plastic water tubes under the roof. The water is heated by the sun and distributed through the house to supply hot water and warm the house. The house also has solar electric panels to generate electricity during the day.
