How much lumber is needed to build a 1500 square foot house?
It should be environmentally friendly and how much does the lumber cost?
Also would it cost to put a roof over the house?

Most lumber is "environmentally friendly" nowadays. Instead of cutting down old growth forests, trees are "harvested" from fast growing trees that have been planted for that purpose by lumber companies. The downside to that is the fast growing lumber is terrible compared to the older stuff.
How much lumber you need depends on the layout of your house. A rule of thumb is one stud for every foot of wall. This allows for doubling up studs for headers, blocking, corners, etc. Take your house plan to a lumber yard and they can do a take off and generate a materials list. They can also give you a cost on the material.
For the roof, it depends on what shingles you choose, the pitch, the configuration (valleys, chimneys, etc.). Figure on $100-150/square (100 sq. ft.) of roof. Keep in mind that 100 square feet of roof does not equal 100 square feet of floor plan. Your roof will have more, and the steeper the pitch the more shingles will be needed.
