Please check this link out:
http://www.igbc.in/igbc/publication.jspFor green home you can consider the following:
- use cfls instead of incandescent lamps
- use solar water heaters
- try to reuse water from washbasins, washing machines for flush/gardens
- use special glass which reduces heat and need for air conditioning
- use special tiles on roof to keep your home temperature within limits
- try to separate bio waste from non bio waste and you may use a composit pit if you have space.....
