The Decision-making Process for Material and Ventilation Rate consideringIAQ and Cost in Apartment Buildings

Indoor air concentration is mainly affected bythe emission rate of contaminants frommaterials and the ventilation rate. Therefore, theappropriate selection of materials andventilation rate is an important factor for indoorair quality. The purpose of this study is topropose a method for the selection of materialsand to determine an appropriate ventilation ratethat can maintain the recommended guidelineconcentration with minimum cost. In order toachieve the objective of this research, anoptimization concept for IAQ and cost wasintroduced, while determinative factors of TAQand cost were deduced and their relationshipswere determined.
