Build new eco-house to promote green house in my country

I live nearby Milan, in a zone with high potential, but without a concrete green approach in building houses. There many constructors that can provide this kind of solutions that must be the future if we want to live in a green world, an house that can sustains its own energy need by itself reducing pollution brought by energy plants.

Building this house has a cost that I cannot afford and I want to start promoting this solution by myself and then proposing same solutions to new house holders and builders.

Fund requested does not cover the whole cost, but simply the difference between a standard building and this one. At the end of April there will be a promotion that allow costs to be reduced, this is the reason I've put the deadline
