碩士 === 國立成功大學 === 建築學系 === 104 === This research uses five steps required to establish the landscape construction carbon footprint evaluation system (urban landscape space). First, separating landscape spaces into five life-cycle stages, comprising 60 years: new materials, construction, daily use, renewal, destruction and abandonment. Second, building up a carbon inventory database for landscape materials. Third, combing EEWH (Taiwan) and IPCC (UN) specifications to settle planting carbon sequestration value. Fourth, calculating and analyzing real landscape projects. Fifth, accomplishing the formula. As a result, even though landscape space has the capability of planting carbon sequestration, but it is completely unable to offset the carbon footprint from materials and daily use (lighting, irrigation, fertilization). According to the life cycle-perspective, when the green-coverage rate drops from 100% to 0%, and only when the green-coverage rate is 100%, there has 0.05 (kgCO2e/㎡˙year) carbon sequestration, when the green-coverage tate varies from 90% to 0%, there is still a carbon footprint value of between 0.93and 10.73(kgCO2e/㎡˙year). Overall, if we want to further reduce the carbon footprint of urban landscape spaces, there are three main steps to take: (1) maximize the green-coverage rate, (2) choose low carbon footprint materials and construction methods, (3) implement high efficient lighting design. Therefore, this research use five steps to build up a carbon footprint evaluation system of urban landscape space. First, separating urban landscape in five stages which are new materials, construction, daily use, renew and abandon in sixty years life cycle. Second, building up landscape materials carbon inventory database. Third, combing EEWH (Taiwan) and IPCC (UN) specifications to settle planting carbon sequestration value. Fourth, calculating and analyzing real urban landscape projects. Fifth, accomplishing the formula. As a result, even though urban landscape has the capability of planting carbon sequestration, but it completely unable to offset the carbon footprint from materials and daily use (lighting, irrigation, fertilizing ). According to life cycle perspective, when green cover rate from 100% to 0%, there is still have carbon footprint value between 0.79 to 8.18 (kgCO2e/㎡˙year). Overall, If whom want to reduce further carbon footprint of urban landscape space, there are three main steps：(1) Maximizing green cover rate. (2) Choosing low carbon footprint materials and construction methods. (3) High efficient lighting design.
