Definitions of Green Building Kats (2003) regards green buildings as buildings that: use key resources like energy, water, materials and land more efficiently than buildings that are just built to code[2].
The concept is used in this paper comes from “the evaluation criteria of green building” and as buildings that maximize conservation of resources (energy, land, water and materials), protect environment and save energy, providing people with healthy, practical and efficient using space, and in harmony with the nature [5].
In Article 40of “People's Republic energy saving law” states that: The government encourages using new wall materials and other energy-saving materials, energy-saving equipment, installing and using solar and other renewable energy systems in the new construction and energy saving renovation of existing buildings.

He[[] He Shanghong Dynamic Simulation of Concrete-pump Hydraulic System[J] Journal of Changsha University of Science and Technology(Natural Science) 2004, Vol.1, No.1 ] used the Power Bond Graph to establish the simulation model of the hydraulic control system of single pump and analyzed the switching process of the system.
The same method was used by He[[] He Guohua, Hu Junke, Wang Qingbiao, Wu Shifei Research on the Reversing Impact of Main Pumping Loops of a Concrete Delivery Pump [J] MECHANICAL SCIENCE AND TECHNOLOGY 2006, Vol.25, No.9 ] and Fu[[] Fu Lei, Qu Fengzheng, Gao Shunde, Miao Yubin Digital simulation of concrete-pump hydraulic system [J] Journa l of Dalian University of Technology 2000, Vol.40, No.1 ] to analyze the impact pressure of the main pump.
Xie used AMESim to establish simulation model for the hydraulic system of the concrete pump and improve the pumping ability of the system[[] Haibo Xie, Shuyong Lin, Huayong Yang, Yu Zhen, Jin Zhang Research on the Dynamic Characteristics of Master Cylinder in the Hydraulic System on Concrete Pump [J] Advanced Materials Research Vols. 317-319 (2011) pp 2398-2403 ].
