Dale, There is an increasing body of literature on product life-cycle optimization that seeks to calculate when product replacement should occur given the mitigation of future energy efficiency gains by the embodied energy of the new products (and disposal of the old). For example, in relation to refrigerators (I have not read the following, so cannot vouch for them): http://linkinghub.elsevier.com/retrieve/pii/S0301421505001126 and in relation to cars: http://pubs.acs.org/cgi-bin/abstract.cgi/esthag/2003/37/i23/abs/es0345221.ht ml Cameron -- Assoc.Prof. Cameron Tonkinwise Chair, Design Thinking and Sustainability School of Design Strategies Parsons The New School for Design Co-Chair, Tishman Environment and Design Center Room 325, 65 5th Ave, New York, NY 10011 On 7/30/08 3:54 PM, "Dale W Jamieson" <[EMAIL PROTECTED]> wrote: > intuitively, some gains in energy efficiency can be obtained without any > technological intervention (e.g., greater use of natural sunlight), while > others would require intervention, perhaps even using technologies that > themselves had high levels of embodied energy or in some way were > environmentally damaging. i'm looking for examples of the later. > > thanks in advance. > > dale > > ********************** > Dale Jamieson > Director of Environmental Studies > Professor of Environmental Studies and Philosophy > Affiliated Professor of Law > Environmental Studies Program > New York University > 285 Mercer Street, 901 > New York NY 10003-6653 > http://philosophy.fas.nyu.edu/object/ > > "A day without sunshine is like night." > >
