平衡綠建築標章申請與車站舒適度之可行性研究－以捷運為例

Abstract

本研究以興建完成及即將興建之捷運車站作為研究對象，探討捷運車站取得綠建築標章的可行性，並分析其與乘客舒適度之間的關聯與矛盾。例如桃園捷運綠線，預計於115年通車七個車站，包含高架與地下車站，實務上目前高架車站相較於地下車站更容易符合綠建築評估項目，尤其在通風與採光條件上具優勢。然而，研究亦發現許多已取得標章的車站，在實際使用中仍面臨通風不良與空調不舒適等問題，反映出綠建築技術面要求與乘客感受間存在落差。 本研究透過專家訪談及國內外案例分析，研究綠建築標章應用於交通設施的制度挑戰與執行困境，並針對捷運車站實地個案進行觀察，彙整高架與地下車站設計特性與實務表現差異。結果指出，現行標章制度於營運階段缺乏有效追蹤與續用機制，導致部分車站標章失效，降低推動誘因。研究成果將提供未來捷運系統設計與中央政策調整之參考，期能在節能減碳與乘客舒適度之間取得更佳平衡，促進公共交通系統之永續發展。

This study investigates the feasibility of obtaining green building certification for metro stations, using both existing and future stations as case examples. It also explores the relationship and potential conflicts between certification requirements and passenger comfort. For instance, the Taoyuan MRT Green Line, expected to open in 2026 (Year 115 in the ROC calendar), includes seven stations—both elevated and underground. In practice, elevated stations are generally more likely to meet green building assessment criteria, particularly due to their advantages in natural ventilation and daylighting. However, the research also finds that many certified stations still face issues such as poor ventilation and inadequate thermal comfort during actual operation, revealing a disconnect between technical criteria and user experience. Through expert interviews and case analyses of both domestic and international transit systems, this study examines the institutional challenges and practical limitations in applying green building certification to transportation infrastructure. On-site observations of metro stations were conducted to compare the design characteristics and real-world performance of elevated versus underground stations. The findings indicate that the current certification system lacks effective mechanisms for follow-up and renewal during the operational phase, resulting in some stations losing their certified status and reducing long-term incentives for implementation. The study aims to provide reference for future metro system design and national policy reforms, seeking a more effective balance between energy efficiency and passenger comfort to support the sustainable development of public transportation.
