(AP) Columbia city officials say they hope an energy-efficient home will be a model for future low-income housing projects.
Habitat for Humanity is building the “net-zero” home, which includes solar panels and a solar water heater, low-flow plumbing fixtures and LED lighting.

About a year ago, the city asked non-profit organizations to submit designs for energy-efficient homes that low-income families could afford.
The house will sell for $107,000. It is expected to be completed in late spring or mid-summer next year.
