Abstract
The use of fossil fuel leads to greenhouse gas emissions, and the
resulting global climate change has become an important issue in the
world. How to reduce greenhouse gas emissions has become an important
goal for all the countries. This study adopts methods such as literature
review, case study, expert interview, referencing group method expert
meeting, expert questionnaire, and constructing a climate database, to
explore the development and strategic planning of zero-carbon green
buildings in Taiwan. The important conclusions are summarized below:
1. This study gathers technical projects related to zero-carbon green
buildings, confirms whether they are workable and whether they
should be medium or long term projects, extracts technical contents
which can be actively applied in the short term, and develops
zero-carbon green building strategies as important references to
choose related technology for architects in initial stages of design.
2. Because of the unconfirmed maturity of technology related to
zero-carbon green buildings, high economic costs (especially high
initial costs and long pay back years), difficulty of system
integration, related regulations, laws, and policies, and differences in
values of those involved, it is still a tough job to achieve the goal of
zero-carbon green buildings. However, the perspective is still good.
3. This study proposes the system analysis for zero-carbon green
building technology database, as references of initial construction of
a future platform for integration and consultation. However, more
applying advanced technology should be considered since it is an

important direction of the development of future information
systems.
4. This study creates a system construction for rebuilding green values,
with 4 constructs including cognition, affection, society, and
economics, and 24 evaluation criteria, as the foundation to evaluate
projects which create high-quality green lifestyle with the highest
influences in the new age.
5. This study creates a meteorological database for 22 places in Taiwan
with hourly meteorological data from an 11-year period from 1999 to
2009. The content of the meteorological database analysis includes 7
meteorological major elements: global solar radiation, dry bulb
temperature, wet bulb temperature, cloudiness, relative humidity,
wind direction, and wind speed, providing architects references for
making decisions related to zero-carbon design.
6. In the aspect of zero-carbon strategic simulation, this study performs
the daily carbon reduction simulation of the zero-carbon strategy
application in a 4-story building in Taipei. After applying the energy
saving strategy to the outside of the building and the management
strategy of reducing the hours with air conditioning and increasing
indoor air conditioning temperature, and setting up small wind
generators and 5kW photovoltaic on the roof, according to the annual
electric power generation evaluation, the accumulated carbon
reduction is 67.6% while 32.4% energy consumption still needs to be
neutralized. Although later fuel cells are used to reach the ideal of
zero-carbon, the cost is too high to be economically efficient.
7. This study performs carbon reduction simulations in north, central,
south, and east Taiwan, including Taipei, Taichung, Kaohsiung,
Hualien, and Taitung. It is found that Taitung is the area with the

highest potential for zero-carbon development. After applying the
carbon reduction measures mentioned above, 85.5% accumulated
carbon reduction is achieved with the building for simulation in
Taitung. The reason is because in Taitung there is sufficient sunlight
all year for solar applications.
