Amid the intensifying threat of global warming, the construction industry has been identified as a significant carbon emitter. In Taiwan, the EEWH green building certification system was es-tablished to reduce carbon emissions in the construction industry through the collaborative efforts of the government and private enterprises to promote green buildings. The system comprises nine indicators across four categories: ecology, energy saving, waste reduction, and health. To explore the benefits of green buildings, this study focuses on consumers in the Taipei metropolitan area and their willingness to buy a house. A literature review summarizes the benefits of green buildings, which then served as the basis for designing a questionnaire. The analysis of the questionnaire results shows that the green building benefits valued by consumers in order of priority are thermal comfort, residential health, a 40% savings on electricity expenses, excellent ventilation, excellent natural lighting, excellent sound insulation, 80% community repair subsidies, and a preferential loan interest rate 0.15% lower than benchmark rates. The study recommends that governments prioritize the "Indoor Environment Indicators" of the Taiwan Green Building Evaluation System by either making them mandatory or in-creasing their weight in evaluations. It also advises private enter-prises to prioritize the indoor environment of green buildings to better meet consumer demands.
