摘要

本研究調查統計台灣地區樑柱工法木構造住宅每1m^2樓（地）板面積所使用之主要結構材料，包含混凝土、鋼筋與木質材料之數量，依各種材料製造時所消耗的能源與排放之碳素量，計算其二氧化碳排放量，並與鋼筋混凝土（RC）構造與鋼構住宅（S）建築物做比較，以評估樑柱工法木構造住宅對碳貯存與二氧化碳減量之貢獻。研究結果發現，樑柱工法木構造住宅每單位建築面積所使用之木質材料材積約為0.2090m^3/m^2。而每單位建築面積所使用建材的CO_2排放量則為47.47kg/m^2。若以樑柱工法木構造住宅取代鋼筋混凝土（RC）構造與鋼構住宅（S）建築物，可削減的CO_2排放量，每m^2為387.71kg/m^2與338.55kg/m^2，顯示樑柱工法木構造住宅在二氧化碳減量與碳素固定上具有顯著的效果。

The objective of this study was to evaluate the CO_2 emission and carbon sequestration under the post and beam (PNB) wooden construction buildings in Taiwan. A total of 53 PNB wooden construction buildings were selected for calculating the CO_2 emission, which generated from construction materials’ energy consumption. The experimental results indicated that the usage of wood materials in per unit construction area was 0.2090m^3/m^2; the CO_2 emission in per unit construction area was 47.47kg/m^2. By comparing the wooden construction with reinforced concrete (RC) and steel prefabricated (S) construction, the CO_2 emission reduction of the wooden construction can reach 387.71kg/m^2 and 338.55kg/m^2, respectively. The results clearly proved that the PNB wooden construction buildings have significant effect on CO_2 reduction and carbon sequestration.
