I've played around with standard investment equations to come up with the
value of investing in energy efficiency as residual equity in a building over
future years (as a function of annual savings, duration of the measure,
etc.). This is done very commonly for other home investments (I've seen
articles on how much value a new kitchen adds to a house, for example). Why
not have the same for a variety of energy-efficiency measures, again based on
sound economic principles? This type of argument might help convince your
friend. Then again, economic equations are not the kind of thing that
fires everyone's imagination. They might need to be translated into
something more accessible, like graphs of the enhanced equity over future
years.
