A Preliminary Methodology For Evaluating The Cost-Effectiveness Of Alternative Indoor Air Quality Control Approaches, Final.

The report defines a simplified methology that can be used by indoor air quality (IAQ) diagnosticians, architects/engineers, building owners/operators, and the scientific community, for preliminary comparison of the cost-effectiveness of alternative IAQ control measures for any given commercial or institutional building. Such a preliminary analysis could aid the user in initial decision-making prior to retaining experts (such as heating, ventilation, and air-conditioning engineers and building modelers) who could conduct a rigorous evaluation. The preliminary methodology consists of text, logic diagrams, and worksheets that are intended to aid the user in (1) assessing which IAQ control option(s) might apply to the specific building being addressed: (2) designing alternative control measures (involving increased outdoor air ventilation, air cleaning, or source management), and developing rough installed and operating costs for these measures; (3) estimating the approximate effectiveness of the alternative control measures in reducing occupant exposure to contaminants of concern; and (4) comparing the cost-effectiveness of the alternative control measures under consideration, to aid in selecting the optimal control approach.
