摘要

綠建築已在台灣發展15年以上，而我國綠建築評估系統始於1999年，稱之為EEWH。截至2015年1月，已有1450個案件得到EEWH之認證。雖然台灣有越來越多的綠建築取得EEWH之標章，但目前在台灣的不動產估價規則中，並沒有包含到綠建築指標之價值。且台灣綠建築發展至今，與不動產價格相關之研究仍然缺乏。故本研究藉由市場資料比較法及迴歸分析法，分別從兩種方面探討綠建築對於不動產價格之影響。
本研究之樣本空間為臺北市/新北市的民間住宿類建築，取自內政部實價登錄網之價格資料，利用特徵價格模型法進行迴歸分析。其實證結果顯示，綠建築價格確實較一般建築來得高，並且其結果與不動產估價法中的比較法估算之結果相似。綠建築之標章等級對於綠建築價格也會因等級之不同而有顯著影響，其中合格級、銅級與銀級隨著等級越高價格越高，而黃金級則比銀級略低一些。
而本文也使用綠建築因子進行迴歸分析及問卷調查，不同的綠建築因子對於綠建築價格有正向影響也有負向影響，而迴歸分析之結果和問卷調查結果多半相符，此結果可提供建商未來設計綠建築做為參考，了解民眾所需之綠建築因子。
綠建築的價格對台灣而言是近期的新課題，而估價師於估價過程中沒有相關知識或統計數據可供參考。本研究結果期望可以提供不動產估價師未來進行估價能有更好的依據，也整理一些國外研究做為參考，希望將來能將永續概念加入不動產估價的評估標準當中，提升國內綠建築之價值，讓綠建築在台灣能夠推行更加順利，創造更永續的台灣。

Green building concepts have been implemented in Taiwan for more than fifteen years, ever since the launch of the Taiwanese green building standards, EEWH, in 1999. Up to January 2015, there have been 1,450 EEWH-certified green buildings. Despite the increasing number of EEWH-certified green buildings, the value of green building certificates is still not reflected in the Regulations on Real Estate Appraisal in Taiwan and research on the correlation between green building certificates and real estate prices is little. In view of this, this research is focused on studying the impact of green building certificates on real estate prices using the Market Data Approach and Regression Analysis.
The sample space of this research is the private green residential buildings in Taipei City and New Taipei City, and the source of data is the Ministry of the Interior. After processing the obtained data using the hedonic price model and regression, it can be observed that green residential buildings have higher sale prices than ordinary residential buildings, which echoes results from the comparison approach in real estate appraisal. Moreover, the level of EEWH certificates will significantly affect the price of the green building. In general, the higher the level of the EEWH certificate a green building has, the higher the green building’s sale price. This is valid for green buildings of certified, bronze and silver EEWH levels. However, the sale prices of gold level green buildings are slightly lower than those of silver level green buildings according to the data.
This research also studied green building factors and conducted a questionnaire survey and regression analysis. The regression analysis result showed that some green building factors are positively correlated to green building sale prices and some are negatively correlated. This result matched the survey result and could serve as good references to construction firms in green building design in the future.
Appraisal of green buildings is a new topic in Taiwan’s real estate appraisal recently. Real estate appraisers hardly have sufficient green building knowledge or statistical data during green building appraisal. Thus, this research, together with relevant research in other countries, would lay good foundation for green building appraisal in Taiwan in the near future. With the recognition of the green building value in real estate appraisal, the promotion of green buildings in Taiwan would become easier, resulting in a more sustainable Taiwan.
