The focus of this study is to compare the experimental measured thermal behavior of traditional and waste materials in residential buildings with simulation results.
It means that waste materials in southern walls could decrease 0.9% to 4.1% of indoor temperature compared with traditional materials.
This validation is considered an initial step to study the effect of using waste materials in the residential buildings envelope, which is applied in walls brick [[] Senthil Kumar, Study of Properties of Geopolymer Eco Bricks, Journal of Civil Engineering 5 (2015), pp. 139-148. ,[] Aeslina Abdul Kadir, Noor Amira Sarani, An Overview of Wastes Recycling in Fired Clay Bricks, International Journal of Integrated Engineering 4 (2012) pp. 53-69. ], and is also considered as a method to improve energy efficiency instead of using traditional materials.
To simulate the thermal conditions, the materials were defined in Design Builder as the same materials implemented in the experimental model, Fig. 3 shows the section of rooms elements in Design Builder a) The walls section of room0 (RO), b) The southern wall section of room1 (R1), c) the roof section of room0 (R0) and room1 (R1).
It is concluded that Design-Builder is a suitable simulation software to predict indoor temperature, which is depending on accurate input data for building such as the used materials U value and type of ventilation.

And the spatial distribution and properties of the structural surface (like geometry, density, filling materials, etc.) [1] play a controlling role in the deformation and failure of rock mass.
The jointed rocks are usually considered as continuous materials [11~13] to calculate the mechanical parameters although they are non-continuous.

The modern industry lets out a huge amount of construction materials.
Development of eco-friendly materials requires the high level of creativity.
The tendency of rapprochement of high technologies and traditional materials was outlined in the 21st century in production of construction materials.
The invention of new construction materials and innovative use of traditional materials demands from scientists-technologists of big degree of creativity, ability to see the necessary properties in unrelated materials.

Abstract.
Finally, a building materials optimization scheme is put forward a kind of fast, reliable program completion, it is never seen evaluation building materials.
It’s scarcely used in optimization of building materials, so we added a process as the lower part in the Fig.1.
Through investigation and analysis, data collection, combined with qualitative analysis in the effect of building materials for building a village, a new village economic evaluation of building materials is established, which contains 3 levels and 14 representativeness indexes (Fig.2).
Conclusion Three indexes with 14 sub-indexes have been used for assessing three different building materials.
