Greenhouse effect has been warming up the earth and threatening human life.
It was found that CO2 emission from buildings contributed more than 30% of greenhouse gas emission in developed countries in 2005 [17]. Buildings also accounted for 39% of energy consumption in this year [52].
Improving thermal insulation of buildings is one of the most effective solutions for the issue.
Therefore, there have been many efforts in developing new insulation materials [20].
