Retrofitting existing homes for energy conservation: An economic analysis.

Examines the economic aspects of energy conservation techniques suitable for retrofitting into existing homes. Includes insulation, storm windows and doors, and weatherstripping. The object of this study is to determine that combination of techniques which will maximise net dollar savings in life-cycle operating costs for heating and cooling operations in existing homes, subject to specific climate conditions, fuel costs and retrofitting costs. Uses micro-economic marginal analysis to find that such a combination must be economically balanced and that each technique should be utilized up to the point where the present value of the life-cycle savings generated by the last increment will just cover the costs of that last increment.
