Energy efficient buildings do not use the energy of environment (i.e. alternative sources) and reduce energy consumption, improving engineering systems of structural elements that determine the nature and intensity of the energy exchange with the external environment (external walls, windows and etc.), as well as optimization of architectural solutions, aimed at reducing energy losses.

Introduction In recent years, global warming and energy problems are become an international concern since the world’s fossil fuel reserves are limited.
In addition, residual stress was also studied since it was a main factor of failure and performance of structural in engineering application.

Unlike a ceramic matrix composite, the reinforcement in a PMC provides strength and stiffness that are lacking in the matrix.
Epoxy resins are considered as one of the most important classes of thermosetting polymers and widely used in various fields of coating, high performance, adhesives and other engineering application.
