While this certainly appears to be a step in right direction towards affordable, sustainable homes, Lloyd Alter raises a couple of pertinent questions on TreeHugger , including this:
If they really buy into it and go for green quality as well as green looks, and insulate the walls and double glaze the windows, this will mean a dramatic improvement in the efficiency and quality of mobile homes. If they are just superficially going for the image and pasting some rainwater collection and solar panels on the roof, it will do nobody any good. We need a build quality and a material selection that matches the design; that will mean thicker walls, less vinyl, no formaldehyde and a slower production line - you can't mix this in with your normal production and get the quality you need to be green.
