Abstract

Background: Houses give off a high percentage of a country’s total carbon dioxide emissions. One way to

cut the greenhouse emissions of houses, and therefore help stop global warming, is to minimize the energy
use. Energy-ef cient glass is regarded as one of the important factors that in uence energy consumption

and carbon reduction of the buildings. Actually, how building’s energy consumption and carbon reduction is

impacted by energy-ef cient glass under different circumstances is worthy of our further research.

Purposes: The main goal of this research is to analyze the in uence of energy-ef cient glass on building’s

energy consumption and carbon reduction. Besides, researchers probe into the degree of its impact under

different circumstances.

Methods: Researchers took the experimental houses which were constructed by Architecture and Building

Research Institute, Ministry of the Interior as the research objects to conduct related analysis and simulation
of energy-ef cient glass. The study was carried out by the following procedures, collecting the parameters of

the energy saving projects, making the simulations, and analyzing the correlation and sensitivity of the glass

factors affecting architecture energy saving.

Results: The results of this research showed that SHGC (Solar Heat Gain Coef cient) of glass has remark-

able in uence on building’s energy consumption, when the outer wall has excellent property of heat insula-
tion, and general window-wall-ration is used. It also showed that SHGC of glass decreases by 0.1, equaling

to lowering about 8.5% of energy consumption of the air conditioner. On the other hand, we found that U

value of glass had slight impact on energy consumption of the buildings with the same analysis and simula-
tion.
