It is the "4R" -- regeneration, reuse, recycle, reduction, to comply with the natural environment and climate condition in layout, to adjust measures to local conditions, local materials for material construction, to attach importance to the adaptation and protection of natural ecological,to coordinate space-function, structure and local building materials , to maximize the use of local building materials and waste materials , to play the natural properties of component materials;to play a component of natural material performance; to emphasize local characteristics and increase the building appreciation value.
On the basis of inheriting traditions, the age requests us to apply modern science and technology and new building materials, and combine perfectly national style, with local characteristics and epochal characteristics.
The best choice for the construction of energy-saving wall is exterior insulation system; in the selection of insulation materials for the thickness of insulation material, technological maturity, material cost and other material into consideration [4].
Moreover the courtyard makes use of the broken brick and the mud filled wall and makes the building materials and waste to be recycled again, that is saving and beautiful.This kind of approach which makes the best use of material, greatly saves building materials consumption.
Try to use recycle materials, increase the utilization ratio of material to raise recycling efficiency after architectural life-cycle.

The invention of self-adhesive flowable composite (SAFC), as the 8th generation of dental adhesive materials, which combines resin composite technology with adhesive materials, so that in one package there is a bonding materials and resin which simplify and accelerate the application of restorative materials [8,9].
In an oral environment, restorative materials exposed and interacts to oral fluids, which can cause discoloration of the restorative materials, intrinsically and extrinsically [12,13].
Acidic beverages can reduce mechanical strength of restorative materials, and it can increase water absorption of restorative materials.
