| Summary: | 碩士 === 國立成功大學 === 土木工程學系 === 103 === The main objectives of this research are: (1) analyzing roadway CO2 emission, (2) analyzing the cost, difficulties, and CO2 emissions of Greenroads indicators, and (3) providing the green strategies for obtaining Greenroads certification. This research studied a case of preparing to apply for the Greenroads certification. First, it reviewed the Greenroads manual to find the requirements for achieving indicators. Then, it interviewed the project designer and contractor, and analyzed the construction documents to summarize the cost, difficulties, and CO2 emissions of various indicators. This research revealed that traditional cost related to green roads is NT$ 2,427,501,000, accounted for 50% of case project cost. The increased green cost is NT$ 75,966,000, accounted for 1.5% of the contract cost. That is, traditional cost takes most proportion of the project cost. CO2 emissions of case project were calculated from material usage, transportation, energy consumption of equipment, site water consumption and site electricity consumption. Material usage accounts for 90.2%, the largest proportion of CO2 emission.At last, the results were used to establish 3D model to prioritize the indicators for Greenroads certification.
