Further analysis showed that the green highlights of the vast majority of projects were reflected in the application of equipment, techniques and materials, and even some projects were up to the standards after the adoption of high-cost active technologies or materials for “patching” in the stage of construction drawing.
Connotation and Economic Features of Green Building 1.1 Connotation of Green Building According to the new version of the Evaluation Standard for Green Building, green buildings refer to those that maximize conservation of resources (energy, land, water and materials), the protection of environment and the reduction of pollution, provide people with healthy, applicable and efficient space and coexist with the nature in harmony in their full life circle.
In addition, as the charging base of design fee is subject to project cost, when the design of green building is more “green”, the use of high-cost technical equipment and materials will be correspondingly reduced and project cost will decrease, thus resulting in a corresponding reduction in design fee.
Qin Youguo [6] once emphasized that “in order to deepen the study of ecological design, architects must pay attention to building technology and science, and ecological building belongs to the laws of physics rather than modeling game”.

The correct estimation of some boundary conditions, for example the heat transfer coefficients between the different materials, results highly complex.
The variables of the simulation models that have been subjected to the correlation process are the material properties, the heat transfer coefficient between the different materials and the boundary conditions needed to reproduce the pouring and the ambient conditions.

Introduction It has been well accepted that the properties of materials strongly depends on their microstructures.
Gibson and Ashby [5] also found that many natural materials have cells looks and behave like a honeycomb.

But titanium alloy TC4 belongs to the typical difficult-to-machine materials, the thermal conductivity is bad, the chemical activity is high, elastic modulus is small, which directly led to the processing sclerosis serious, low cutting speed, short cutting tool life, and lower processing efficiency.
The experiment tool is three blade solid carbide end mill, materials is YG8, cutting tools length is 65 mm, tool diameter is 10 mm, former angle is γ0=12.5°, spiral angle β=34.5°, cutting part in length is 30 mm.

Onundi et al. [6] reported that certain solid materials possess a high affinity for heavy metals, this enables the removal of such metals from a solution by attachment to the solid surface with high efficiency.
A number of low cost adsorbents have been tried from industrial and agricultural waste to find alternative materials to the commercial activated carbon for dye removal.

Biochar is cheap and more sustainable as it does not require chemical reagents and can be made from waste materials [5].
Based on Yu et al. the biochar made at 850°C rather than 450°C showed greater affinity for sorption of organic materials because of its higher surface area and nano-porosity [7].
Biochars produced in high temperature would have high surface area and large pore size that are applicable for sorption of substances including heavy metals and organic materials.
