After years of promotion, green building and its benefit are gaining more and more attention in Taiwan. Besides the establishment and implementation of related regulations, several commercial buildings and some private residential buildings have also been constructed following the “green” guidelines for the sake of sales It seems the concept of green building has become another mainstream values of construction sector in Taiwan. The main purpose of this study is to demonstrate the utilization of the Green Building Indicators and Evaluation System, which was developed by the Architecture and Building Research Institute of the Department of Interior Affairs. Two real residential cases were studied and each one of the indicators was calculated and compared with the benchmark values. Results of the study showed that green building is neither costly nor difficult to achieve. On the contrary, a little extra effort on the “design” stage will benefit a lot during the “use” stage. Some suggestions and recommendations are also proposed for government, industry and academia to further expand the utilization and application of the concept.
