Insulate existing buildings
Which ones?
In what cases is it worthwhile to add more insulation? How can we determine whether the energy saved outweighs all the environmental impacts of doing the renovation?
Case studies
This section has not been filled in yet.
Cases worth studying: Houses, apartment complexes, commercial buildings and more. Built during various eras, both older and more recent. Consider the challenges of dealing with lead paint, asbestos, and other complications. Consider the environmental impacts of new materials involved (i.e. if walls and roofs have to be torn up and rebuilt).
