Pencils sharpened, class, because Inhabitat's lecture of the week is on Materials and resources, and it is a big topic so pay attention. Your Cliff Notes version, without their lovely pictures and prose:
-Get small. We always talk about living with less; It now pays LEED points.
-Get efficient. frame your building carefully and think about prefabs or SIP's.
-Get Local. Don't pay to ship materials across the country or the world.
-Build to last. Houses should last a couple of lifetimes.
-Pick your materials carefully. Think FSC.
-Don't waste. Anything.
That is the crib sheet, see the whole lesson at ::Inhabitat
