| Popis: | 95 Wooden construction buildings use wooden products as the main construction materials; therefore, they consumed less energy and reduce carbon dioxide emissions than other kinds of buildings did during construction process. Meanwhile, wooden construction buildings could sequestrate carbon within buildings during their life time. The evaluation methods of carbon sequestration in harvested wood products have been taken into discussion by IPCC. The dissertation is focus on wooden construction buildings to analyze their current market situation and to evaluate their contribution of carbon sequestration and carbon dioxide reduction. Results indicated that the platform (2 X 4) and post and beam (PNB) wooden construction buildings were the major types of wooden houses which shared approximately 70% of total wooden houses in Taiwan. Both spruce-pine-fir and Douglas fir were used as construction materials mostly. The following problems were perceived by wooden house construction companies, mostly related to their future concerns: lumber prices, labor costs, fluctuation of business cycles, competition from non-wooden houses, domestic construction laws and regulations, and disposal of wooden waste. The usage of wood materials in per unit construction area of wooden construction houses was 0.2133 m3/m2 ; and the carbon dioxide emission in per unit construction area was 54.41 kg/m2. Comparing the wooden construction with reinforced concrete (RC) and steel prefabricated (S) constructions, the carbon dioxide emission reduction of the wooden construction are 388.21kg/m2 and 339.05 kg/m2 of two previous major methods, respectively. The results showed that wooden construction buildings have significant ability in carbon sequestration and carbon dioxide reduction. The quantity of carbon sequestration is estimated to be 65 thousand tons until 2012, and it is expected to increase 3,800 tons per year during 2013-2017 by the stock change approach. |
