PowerHouse Enterprises PowerPod
This demo model, originally built for a green building trade show, sits in a former coal-fired power plant in Lawrence, Mass., a city best known for its former textile mill industry.
From the outside, the most distinguishing feature of the PowerPod is its roof line, designed for both passive and active solar energy. Called the Solar Butterfly, the sloping roof allows sunlight in for heating and lighting during the winter months. The shorter south-facing roof holds a solar electric array and a hot water heating system.
