Should I include loads of soil, stone, pipe bedding materials, underground pipe, catch basins or other site work materials to the total cost of materials? Credit requirements say, "Include materials permanently installed in the "project". Does "project" mean only the physical building or outside our building like the concrete drive?
If they do contribute, can stone and soil be counted as regional materials? Can all concrete be counted as recycled or regional materials then or is it just Fly Ash that's recycled in concrete?
