The paper proposes a methodology for evaluating and ranking specific alternatives for control of indoor air quality in existing buildings, based on comparative costs and benefits. The method avoids the difficulties of assigning a monetary value to a change in air quality by adjusting the air exchange rate in each alternative until equivalent indoor air quality is achieved. The difference in air exchange rates between alternatives allows calculation of energy savings, which can be compared to capital cost savings,which can be compared to capital cost using the payback period method. The method is applied to the case of gas range emissions, evaluating two alternatives, replacement with an electric range or installation of a vent hood. The payback period for these were 28 years and 14 years, respectively.
