Let's see. Green is:
Not today! High-performance homes (including Energy Star and GreenBuilt) are available in traditional styles and in all price ranges. You need to see this for yourself, and the Parade of Homes is the perfect opportunity! This year's Parade is on the first 3 weekends of October.
Things to look for (besides price, location, and style):
Some features to check out are radiant barriers, foam insulation, tankless heaters, low-e windows, low-VOC paints, and local materials. Check out building practices such as waste reduction, site preparation, and advanced framing materials and techniques.
Finally, ask about Energy-Efficient Mortgages and tax credits. It's worth your while - save money on your purchase, at the same time you cut your monthly energy expenses!
