| Summary: | 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.
