dc.description.abstract | “The World Summit on Sustainable Development” at Johannesburg in South Africa on August, 2002 declared that the ambition of 21st century is to seek sustainable development. In the past, Taiwan seriously ignored the sustainable operating in constructional process to pursue economics. In addition to conclude 2003 as”The First Year of The Sustainable Era”, Public Construction Commission, Executive Yuan also drafted ”The Medium-Term Summary Plan on Sustainable Development in Public Construction” which includes the sustainable operation and strategy on constructional configuration, development and eco-building.
According the internal research, the CO2 discharge rate of Taiwan constructional industry is up to 28.8% of the total CO2 discharge rate in Taiwan. From building, decorating, using to dismantling a construction, it consumes a great deal of energy, water and resource, and the expense on operating stage costs over half of the total constructional life cycle cost. Even, the needs of material, energy consuming and equipment to establish a high-riser building are much larger and expensive than a general one. In order to advance the economic benefit on public construction, the ways to analyze the constructional life cycle cost and to judge the benefit both on new-built and existing construction to minimize the economic impact, to extend construction life by effective plan, to reduce maintaining operation cost are the important issues to reach sustainable development.
This research uses the information of 10-year records, recent stats, statute reference and constructional capitalized costs on public high-riser constructions to generalize the maintaining management in operating stage and its main work. This is to provide the decision-makers, executors and managers an estimative reference on related constructional engineering in the future. | en_US |
