整體開發地區綠建築溢價之研究

二氧化碳及其他溫室氣體排放造成全球地表溫度持續升高，目前已有超過120個國家提出在2050年之前達到淨零排放的目標，我國國家發展委員會於2022年3月公布「臺灣2050淨零排放路徑及策略總說明」，以2050年100%新建建築物及超過85%既有建築物為近零碳建築為目標，綠建築為實現淨零排放目標方式之一。但過去研究因樣本數量有限、研究範圍過大等因素造成研究樣本間屋齡、環境因素差異過大，本研究試圖釐清如果在屋齡相近、區域環境類似情況下比較綠建築與非綠建築間之房屋價格差異，綠建築是否有溢價存在？本研究以臺北市北投奇岩新社區，新北市新莊副都市中心地區，桃園市高速鐵路桃園車站特定區共三個整體開發地區為研究範圍，彙整2016年~2021年內政部實價登錄資料，建立特徵價格模型進行分析，實證結果顯示，臺北市北投奇岩新社區綠建築標章溢價率為3.52%，銀級溢價率為3.52%；新北市新莊副都市中心地區綠建築標章溢價率為13.63%，銀級溢價率為13.61%、黃金級13.96%；桃園市高速鐵路桃園車站特定區綠建築標章溢價率為8.55%，銀級溢價率為7.17%、黃金級18.53%，呈現綠建築標章等級越高、溢價率越高之情況，且桃園市高速鐵路桃園車站特定區綠建築標章銀級與黃金級間間溢價率差異可達2倍以上。不同整體開發地區相同綠建築標章等級，雖然溢價率不同但溢價金額相近，因各整體開發地區綠建築標章溢價率不同，所以不同縣市及地區應考量區域環境特性、當地房價水準、周邊鄰里設施等條件分別訂定綠建築標章取得與獎勵規定。

Carbon dioxide and other greenhouse gas emissions have caused the global surface temperature to continue to rise. At present, more than 120 countries have proposed the goal of achieving net zero emissions by 2050.In March 2022, National Development Council announced the "Taiwan’s Pathway to Net-Zero Emissions in 2050",with the goal of 100% of new buildings and more than 85% of existing buildings being near-zero carbon buildings by 2050.Green buildings are one of the ways to achieve the goal of net zero emissions. However, due to factors such as the limited number of samples and the large research scope in previous studies, the age of houses and environmental factors between the study samples were too different. Compare the difference in house price between green buildings and non-green buildings under different circumstances, is there a premium for green buildings? This research focuses on three overall development areas, namely, Beitou Qiyan New Community in Taipei City, Xinzhuang Sub-Metropolitan Area in New Taipei City, and High-speed railway Taoyuan station specific area in Taoyuan, established an hedonic price model for analysis, and the empirical results show that the premium rate of green building labels in Beitou Qiyan New Community is 3.52%, and the premium rate of Silver level is 3.52%. The premium rate of green building label in Xinzhuang Sub-Metropolitan Area is 13.63%, the premium rate of Silver level is 13.61%, and the premium rate of Gold level is 13.96%. The premium rate of the green building label in the High-speed railway Taoyuan station specific area is 8.55%, the premium rate of Silver level is 7.17%, and the premium rate of Gold level is 18.53%, showing that the higher the green building label level, the higher the premium rate. The difference in the premium rate between the green building label Silver and Gold in High-speed railway Taoyuan station specific area can be more than 2 times. Different overall development areas have the same green building label grade. Although the premium rate is different, the premium amount is similar. Because the green building label premium rate is different in each overall development area, different counties and regions should consider the regional environmental characteristics, local housing prices, surrounding areas. Neighborhood facilities and other conditions are separately stipulated for obtaining and rewarding green building labels.
