碩士 === 國立交通大學 === 工學院碩士在職專班工程技術與管理組 === 98 === In this study, the existing building of Qing-Shui service area was evaluated with EEWH-NC 2009 ed., and LEED-NC 2009 ed. green building evaluation system. The applicability of EEWH-NC for existing building was addressed. Suggestions on improvement of Qing-Shui service area to meet EEWH evaluation system were proposed. Suggestions on EEWH-NC evaluation system were made by comparing EEWH with LEED. Belows were EEWH-NC evaluation results. There were 3 evaluation items passed, one was making green (without “soil cover depth”), another was water resource, and the other was improvement on sewage and garbage. The evaluation items of CO2 emmision reduction and construction waste reduction were not used, since this is an existing building and was not in the construction stage. These two items are not suitable for existing building. Other items can be passed after improvements. It will pass EEWH copper lable after improvements. The evaluation results based on LEED were failed due to low score and failed on prerequisite item. Some items of LEED-NC are not suitable in this case. However, it will pass the LEED certified level after improvements. iv Suggestions for applying EEWH-NC to existing building were stated as belows. Firstly, the evaluation items of CO2 emmision reduction and construction waste reduction should be removed. Secondly, to remove the rule of “soil cover depth” for well growing trees over two years is suggested. Thirdly, to remove the constraint on maximum air conditioner capacity in energy saving for large existing department store building with high occupany rate is suggested. The constraint may affect the life cycle of air conditioner and the thermal comfort of occupants and customers. Fourthly, adopt the idea “site-development-protect or restore habitat” from LEED rather than the current practice “destroy-then-build” in Taiwan. This way, the existing green field can be preserved/restored and the biodiversity can be maintained naturally. Finally, the differences between EEWH-NC and LEED-NC evaluation systems were studied. Suggestions on EEWH-NC were listed as belows. Firstly, extending the coverage range of EEWH-NC to EEWH-EB to include existing buildings. Secondly, comprehensive evaluation items should be avoided in EEWH due to subjective opinions of different evaluators. Thirdly, it should be more open-minded when making and modifying the evaluation system. This can be done by collecting valuable ideas from experts, scholars and those who work in green building industry using enhanced networked platforms and forums.
