eco friendly homes

O.k. I have a few questions about having a green home:

1. Is it true that eco-friendly homes cut the percentage of having a cold or being sick?

2. What type of floors are best, baboo, wood, carpet, what?

3. Type of lighting; what are good lights that you can use?

4. What are good furnitures; that don’t absorb alot of dust.

5. What is a good location for having an eco-friendly (or green home) home? The city, the suburbs, a farm, near an ocean?ect..

6. Last would the payment of lighting, water, electricity, be less? Meaning would the percentage of paying be less?
