Decision Model to Optimize Indoor Air Quality <strong>in</strong> Commercial Build<strong>in</strong>gsProject DescriptionPurpose <strong>of</strong> the ResearchThe purpose <strong>of</strong> this research is to develop a decision model for optimiz<strong>in</strong>g the control <strong>of</strong><strong>in</strong>door air pollutants <strong>in</strong> commercial build<strong>in</strong>gs. This research will help decision makersdeterm<strong>in</strong>e the optimum <strong>in</strong>door air management options <strong>in</strong> order to maximize the benefits<strong>of</strong> a better IAQ’s by us<strong>in</strong>g mathematical programm<strong>in</strong>g.Literature ReviewThe relation <strong>of</strong> human with build<strong>in</strong>gs is the essence <strong>of</strong> architecture and build<strong>in</strong>gconstruction. Fitch def<strong>in</strong>es the ultimate task <strong>of</strong> architecture as “to act <strong>in</strong> favor <strong>of</strong> humanbe<strong>in</strong>gs” (Fitch & Bobenhausen, 1999). The environmental management concepts,techniques and their <strong>in</strong>fluence on build<strong>in</strong>g design, construction, and themes have beenchang<strong>in</strong>g.

Intake air is mostly provided by outdoor air and <strong>in</strong>some cases by re-circulat<strong>in</strong>g the exist<strong>in</strong>g air. However, re-circulated air should usually beavoided s<strong>in</strong>ce it may <strong>in</strong>crease the levels <strong>of</strong> pollutants. The system should be designedwith fresh air <strong>in</strong>take strategies whenever is possible. The reason fresh air <strong>in</strong>take should beused is that <strong>in</strong> many cases outside air will ensure a sufficient amount <strong>of</strong> air filtration.Natural ventilation can provide outside air as long as the energy efficiency <strong>of</strong> the build<strong>in</strong>gis kept at acceptable levels.The amount <strong>of</strong> <strong>in</strong>door air pollutants is correlated with different build<strong>in</strong>g conditions suchas the site, build<strong>in</strong>g materials, construction techniques and HVAC system.
