綠建築評估項目對住宅不動產估價調整率之影響IThe Influence of Green Building Indicators to the Percentage Adjustment of Valuation on Residential Building
In order to understand real estate appraisers’ opinions on green building price assessment, this study conducts surveys and performs analysis based on “Green Building Class” and “Analytic Hierarchy Process (AHP) Questionnaires”. The results of this study show that real estate appraisers are willing to raise the average appraisal price by 9.77% for those green buildings that have obtained the green building mark. Moreover, the first three green building indicators that have the greatest impact on the green building valuation are “indoor environment”, “energy-saving equipment” and “air-conditioning system”. The empirical analysis confirms that when the green building level is higher (the total score is higher), the green building premium will also increase. However, when the green building level (total score) reaches a certain level, the increase in the premium will tend to be flat. Finally, this study presents a “Residential Green Building Valuation Application Form” as a reference for real estate appraisers in valuation practice.
Key words: green buildings, green building price premium, real estate valuation
