Abstract
Green building has become one of the most efficient measures to pursue a
sustainable built environment over the past fifteen years. Therefore, the government of
Taiwan established the Commission on Sustainable Development in 1996 under the
Executive Yuan, to come up with policy guidelines and implementation plans. The
concept of green building and its corresponding promotion programs were thus initiated
from 2001, and continued developing to Eco-City and Green Building Promotion Act.
The major outcome of the research plan at the first stage was to establish a green
building evaluation system that was capable of accommodating the subtropical/tropical
climate condition and local environmental issues, and providing quantitative formulae and
explicit criteria to effectively increase its operational feasibility. Taiwan’s green building
evaluation system was first announced in 1998. The current evaluation system, integrated
with nine indicators, was thus set up. These indicators can be divided into four categories,
Ecology, Energy Saving, Waste Reduction, and Health (known as EEWH system). In
addition to the evaluation tool itself, a Green Building Labeling system for green building
certification was also established in 1999. The certification now consists of two parts:
Green Building Label for completed buildings, and Green Building Candidate Certificate
for building projects. The minimum requirement for green building certification is to pass
two prerequisites (energy saving and water conservation), and two optional indicators
from among the other seven indicators. In 2007, a new rating system was established to
aim at improving green building design, which was classified into five levels: certified,
bronze, silver, gold, and diamond. Moreover, for green building education, the ABRI also
published a standard manual for Green Building and Green Building Material evaluations
that had been distributed widely to building designers, teachers, architects and
contractors.Until Sep. 2010, there were 2,624 Green Building Candidate Certificate cases,
and 553 Green Building Labels for completed building in Taiwan.
This research focuses on the energy saving issue of the office building cases of the
553 Green Building Labels for completed building. By investigation of the electric energy
consumption of green office building, 38 cases had been collected from the management
officer or owner. On the second, we analysis the monthly electric energy of a individual
green office building case. There shows that in the running season of air conditioning
system, the electric energy consumption increases obviously. And the capacity of AC
system correlate with energy use intensity (EUI) partly. The other design factor, such as

total floor area (m2), classified year, number of users, existes no correlation with EUI. And
the next, the research evaluates the EUI of green office building by zoning, building
position, summer and non-summer time. The EUI of green office building in northern
Taiwan is higher then in middle and southern Taiwan. And the EUI analysis of different
building position shows that the west position is higher than north and south.
Furthermore, the research evaluates the electric energy saving and CO2 reduction of
the completed green office buildings and Green Building Candidate Certificate cases. By
the floor-area of completed green office buildings, the electric energy saving volume is
nearly 7 7,485,917 kWh (50,212,549 kg-CO2). And by the floor-area of Green Building
Candidate Certificate cases, after the buildings established to daily use, the electric energy
saving volume wiil be nearly 421,720,000kWh (262,731,629 kg-CO2). The benefit of
Green building Policy is significant in Taiwan.
