The San Diego Union-Tribune reports that architect Michelle Kaufmann, termed “the Henry Ford of green homes” by the Sierra Club, says in order to attract people to energy efficient modular homes, we have to make it less expensive to live in than what people are paying now.  She says we need to think of not just the mortgage, but demonstrate that the monthly energy bill is lower.  If you can show people monthly savings, that is powerful.  She says conventional home building has been the same for years and it is wasteful.  Kaufmann, who has displays in Washington, D.C. and Chicago, says building green modular homes should not take any longer than building non-green.
