Push to build "green" homes picks up steam

By Karen Jacobs

LOS ANGELES (Reuters) - Soaring energy costs and increased concern about the environment are spurring builders to step up building homes that use less energy and water.

More than 30 affordable homes being built this week during a Habitat for Humanity project in Los Angeles include materials designed to reduce energy costs and save the new homeowners money.

"Green building certainly is becoming more mainstream within the affordable housing community," said Ted Bardacke, senior program associate with Global Green USA, an environmental group that works with housing developers.

Homes being constructed during the weeklong Habitat project, an annual event hosted by former President Jimmy Carter to build homes for lower-income families, include solar panels on the roof that generate energy, double-pane windows and energy-saving lights and ceiling fans.

This year, the Carter project is seeking LEED (Leadership in Energy and Environmental Design) certification -- a U.S. standard that identifies buildings that are environmentally responsible and have lower operating costs.

"Energy over time is only going to get more expensive," Bardacke said. "In serving low-income families, we have to recognize that a truly affordable house is not just a house that's affordable to buy, but is more affordable to operate."

Appliance maker Whirlpool Corp is donating water- and energy-saving washing machines and refrigerators to the Habitat homes, while Dow Chemical Co provided exterior housewraps and insulation to minimize air leakage and control moisture.

To promote construction of energy-saving buildings, Dow said it is launching products including an insulated sheathing made with a high percentage of recycled material.
