Abstract
1. Introduction
The global warming after 21st century has caused the sea ice in the Antarctica and Arctic to
melt, unusual climate, etc. These phenomena have revealed that the enormous emission of
CO2 has seriously damaged the global environment. To confront the continuously increasing
CO2, relevant international agreements have been signed in succession, and cross-country
conferences related to CO2 reduction have been held, such as COP15 in 2009, in hopes of
achieving new global climate agreements for replacing the Kyoto Protocol and the United
Nations Framework Convention on Climate Change (UNFCCC or FCCC in short).
Aiming at low-carbon green buildings, the Love Taiwan 12 projects were brought up in
Taiwan. Furthermore, governance guidelines, such as Green Building toward Eco-city
Promotion Program as well as Energy-Saving and Carbon-Reduction Action Plan, and the
conclusions of the national energy conference, Low-carbon Homeland, have been employed
to develop low-carbon technologies and to thus make progress toward low-carbon green
buildings and carbon-reduced eco-cities.
In terms of daily energy consumption and the energy consumption of building materials, the
buildings in Taiwan account for 27% of the total CO2 emission. Green buildings are the key
for architectural authorities to promote sustainable development and how they can slow down
energy consumption. However, at present, Taiwan still lacks relevant research on building life
cycle cost (LCC) analysis and life cycle CO2 (LCCO2).
2. Research approach and course
Internationally, CO2 reduction is the primary target to confront global warming. The methods
for analyzing the life cycle CO2 (LCCO2) and the life cycle cost (LCC) of buildings are
employed to bring up an appropriate methodological framework of the life cycle CO2
(LCCO2) of green buildings and proper energy-saving design strategies. This study will take
government offices as examples and, by means of collecting internationally the methods and
theories of building life cycle cost (LCC) analysis, calculate the life cycle cost (LCC) and life

cycle CO2 (LCCO2) of the cases to induce the energy-saving design strategies of the
building life cycle of government offices.
3. Important discovery
From the perspective of CO2 emission, this study intends to establish the framework of green
building life cycle cost (LCC) as well as induce and evaluate the energy-saving design
strategies of government office buildings. Within the project schedule, it is expected to
achieve the following goals:
1. Compiling international methods or theories of building life cycle cost (LCC) analysis
and bringing up literature review and analysis results.
2. Establishing a methodological framework of green building life cycle cost (LCC)
analysis.
3. Inducing and evaluating the energy-saving design strategies of the building life cycles of
government offices.
