From the outside, the smart, green home doesn't look any different from others in the neighborhood. On the roof, however, are 22 solar photovoltaic panels, which produce up to 5 kilowatts of power, and an array of solar hot water panels. The building is a three-family unit with the owners living on the second floor. They were able to rent out the other two units within a few weeks.
