| Summary: | 碩士 === 中華大學 === 土木工程學系 === 105 === According to Taiwan Central Weather Bureau climate data, the average temperature of
the past decade in Taiwan is the highest of the past one hundred years. Furthermore, the
temperature increase in Taiwan is higher when compared to global data. In addition, the
Urban Heat Island effect is more serious in Taiwan due to the large concentration of city
population. In summer, the temperature difference between Taiwan city center and its
surrounding area can be as large as 3 to 4℃. Green Roof, by definition, is the effective use
of the roof of the building that transforms the space into a colorful, low-maintenance roof
garden. Due to the fact that the weather of Taiwan is good for plant growth, it is quite
suitable to promote building Green Roof in Taiwan as a mean to compensate for the lack of
green space and reduce the Urban Heat Island effect. The purpose of this study is to collect
and analyze information on different types of existing Green Roof and to summarize the
assessment factors that will affect the choosing of Green Roofs. The goal is to provide
schools with guidelines for building a Green Roof so that teachers and students can enjoy
the benefits that a Green Roof provides.
In order to properly select the best school building to build the Green Roof, the
following condition must be observed : (1) the condition of the building, (2) the climate
that the building resides, (3) the structure of the proposed “Green Roof” type and (4) the
cost of Green Roof maintenance management. Assess the status of the building and the
amount of budget, carefully select the appropriate type of the Green Roof is the most
important decision when building a Green Roof. Among these factors, the condition of the
building and the external climate are regarded as innate factors; green roof structure system
and management and maintenance cost are regarded as the external factors.
The study shows, by using the criteria outlined above, the most suitable type of Green
Roof for the Hsin-I Building at Hsinchu Municipal Zai Xi Elementary School is Extensive
iii
Green Roof . According to the information provided by the General Affairs Office of Zai
Xi Elementary School, the total area on the roof of Hsin-I Building is about 912.66m2
. The
yearly maintenance cost is about NTD 185000 to 276000 if Extensive Green Roof is built
on the roof of Hsin-I Building at Zai Xi Elementary School
