The Sierra Club has an awesome site called Green Home. You can calculate your CO2 footprint, find a local bamboo flooring retailer, learn about passive solar options to reduce energy costs and much more! It is a great one-stop resource for finding ways to implement sustainable practices in your home.
The New York Times has a video about the project called Home Green Home: Rich Green, Poor Green. It illustrates examples of luxury apartments with a green roof, solar panels built into the facade, all high-efficiency appliances, and a built in water treatment facility – all the way down to ways in which you can green your old home yourself.
What do you think constitutes a “green” home?
