自用住宅因為銷售金額高對一般人而言並非投資性商品，購買者大多一生只購買一次，且以自用居多。由於不動產開發商之住宅開發專案的決策評估，常以市場銷售導向為主要的考量因素，加上產業競爭激烈現象，讓不動產開發商除了著重建築外觀的豪華設計來吸引顧客外，亦在建築物的室內公共空間使用高級的進口建材，往往忽略健康建材的使用及忽略了舒適的室內空間設計。為尋求自用住宅的居住舒適度及符合顧客的需求，本研究結合德爾菲法、層級分析法(Analytical Hierarchy Process,AHP)及效用理論(Utility theory)等三套決策理論，發展一套以顧客健康為導向的住宅舒適度評估模型，用來評估、比較各項自用住宅的居住品質，使房屋供應商在產品推出前的評估過程，有一套兼顧銷售與顧客健康的評估工具，提高決策的有效性及降低投資風險。

Buying a house for personal use is an infrequent investment for most people because of the high sales cost. Most buyers only make one housing purchase in their lives, most often for personal use. Real estate developers evaluate decisions for housing development projects often according to market- and sales-oriented factors. In addition to the fact that the industry involves fierce competition, real estate developers frequently neglect using healthy building materials and comfortable interior designs, focusing instead on a luxurious building facade to attract customers and the use of high-quality imported materials in the common spaces inside the building. To identify the factors affecting the comfort of living in houses and satisfy customer demands, this study combined three decision theories, Delphi method, the analytical hierarchy process and utility theory, to develop a customer health-oriented housing comfort assessment model. This model can be used to assess and compare the quality of living of various houses, providing housing agents with an evaluation tool that accounts for both sales and customer health that can be used in the evaluation process before a house is introduced to customers. Thus, the effectiveness of decision-making can be improved and the risk of investment reduced.
