Awareness about indoor environmental quality (IEQ) is very lower than where it should be. Consequences of this unawareness can be more devastating and can extend from inefficient energy consumption to non-affordable business. It has caused extensive economic and health related issues for humans. It should be envisaged that IEQ even in residential buildings could effect on workers performance in their workplaces as they spend approximately 50 percent of their time including sleeping hours in their places of residence. Moreover, workers’ salaries cost some times more than energy costs for large commercial buildings thus reducing absenteeism and increasing workers performance and productivity can provide large amount of cost saving for commercial sector. In this study, combinations of practical and theoretical approaches are proposed to illustrate different aspects of IEQ. First of all, IEQ is introduced comprehensively. After that relation between building post occupancy economy and IEQ is investigated. Then, from varies methods of IEQ evaluation, one method is chosen and applied through residential buildings in Istanbul. Results have shown that inappropriate thermal conditions, noise and mold are three main indoor problems which can be solved by considering some evaluations during design stage of building at no or less possible cost.
