Here are some frequently asked questions about green home remodeling and additions.

Why is now the time for green home remodeling and additions?

There are really so many practical reasons to go green right now: Decreasing toxic off-gassing and harmful air pollutants that are part of traditional construction materials. Reducing global warming, increasing energy efficiency, and energy independence, conservation of resources.

Does it cost more for green home remodeling and additions?

Not with a balanced approach to green. If you want to go LEED platinum, then these will cost you more. But even so, a 2007 study showed that consumers tend to over estimate the cost of green. In fact, even if you do go all out, the cost is only 5% more in construction costs. But whether you go LEED platinum or gold, your green home remodeling and addition has to make sense for you and your family. Experienced green contractors, such as Green Planet Building in Los Angeles, say they like to take a balanced approach to green, focusing on health and energy efficiency, while staying within your budget—green or not. Of course, keep in mind that energy efficiency pays for itself over time and green homes are more attractive in tight real estate markets.

So what does it mean to be doing "green" home remodeling and additions?

Again, that depends on what makes sense for you. Many families do home remodeling and additions for a new child that's on the way and want their children's new room to be protected from the toxic air pollutants that are in conventional paints, flooring, and other building materials. Others simply want to save money through better insulation, windows, and new appliances. Ask a qualified green contractor to evaluate your goals for home remodeling and additions, and see how they can be given a green touch.

How can I tell a contractor is qualified to do green home remodeling and additions?

There are several local and non-profit green building organizations that train and certify contractors. For example, Green Planet Building is certified by Build-It Green, a non-profit organization that promotes healthy, energy-and resource-efficient building practices in California. They're also members of the U.S. Green Building Council, creator of the LEED standard. And just like any contractor who does home remodeling and additions, a green contractor should be licensed and bonded.
