行政院環境保護署指出國人每人每天約有80-90%的時間處於室內環境中（包括在住家、辦公室或其他建築物內），因此室內空氣污染物對人體健康影響應當受到重視，有效改善室內空氣品質，方能維護人體健康。本研究選擇我國於2011年所通過的「室內空氣品質管理法」，作為主要分析主題，百貨公司為環保署公告第一批公告列管場所之一，其管制區域面積大，並且營業場所販賣物品具多樣、複雜性，在不同季節、假日及非假日的進出人口數差異較大。本研究旨在探討百貨公司室內空氣品質之認知與評價，透過新光三越信義新天地的個案調查，以問卷調查法分別就A11館內部員工，以及平日與假日前來消費的民眾作為研究對象，共計回收有效問卷630份。本研究的主要發現有：1.內部員工高度肯定百貨公司的室內空氣品質；2.個人背景影響對（室內）空氣品質的認知；3.實際經驗與知識反應品質管理的優劣；4.加強宣傳與檢測管理是改善評價不良的重要策略。
