Abstract

Background: The current amount of existing buildings is more than 97 % of all buildings in Taiwan. These
buildings have high energy consumption and cause harm to the ecological environment. Architecture and

Building Research Institute(ABRI) start to execute the "Building Energy Saving and Green Remodeling Proj-

ect" at 2003. In addition to reduce the power consumption with outer perimeter zone air condition of the

building, it can also improve the indoor thermal load signiicantly. However, these improving techniques
only estimate it's energy-saving eficiency by experience, and be short of the exact way to quantify the ben-

eits of the improving energy eficiency and indoor environmental comfort.

Purposes: It will analyze the relevance between energy-eficiency and thermal comfort of the indoor envi-

ronment. And analyze what improving method is better for improve effectiveness. It can be the reference of

assess the beneits beforehand.

Methods: It will use EnergyPlus to simulate the air conditioning power consumption and the thermal com-

fort of the indoor environment with the index of PMV and PPD, which according to different types of exte-
rior sun-shading, climatic parameters and direction etc.

Results: It had set up the simple estimating energy savings mode for exterior sun-shading improvement.
And further, it had analysis the air conditioning power consumption and the thermal comfort of the indoor

environment in Taipei, Taichung, Kaohsiung, Hualien etc four regions, and as horizontal, vertical and lattice Jo
ur
three types of exterior sun-shading respectively.

Conclusions/Implications for Practice: In terms of whole story building (including inner and outer pe- alt
h a
ripheral area) in Taipei, the air-conditioning energy-saving rate is about 6 to 10%, and the total energy sav- nd
Arc
ing ratio is about 3 to 5% when the building toward the east, south, west and north. In addition, the air- hit
conditioning energy-saving rate is about 4 to 8%, and the total energy saving ratio is about 2 to 4% when ect
ure
the building toward the southeast, southwest, northwest and northeast.
