Study on the energy-saving design of underground building Nan Li Deptment of Resources and Civil Engineering, Shandong University of Science & Technology, Taian, Shandong , China; linan96@126.com, Key word: underground building  lighting ventilation energy saving Abstract: With the rapid development of national economy, energy saving, emission reduction and low carbon economy is paid more and more attention, the construction is the major energy consuming of all energy intensive industries, energy saving and emission reduction of underground building which is represent the general trend, this paper is based on the analysis of the characteristics of the underground space, the effective energy saving measures from the lighting, ventilation are proposed, in order to achieve the best effect to reduce the energy consumption.
Choose the right light guide way and the right guide light material is the key step in design. 
Design of underground building artificial lighting should be based on the use of underground engineering, space size, architectural form, material, color and form of the smoothness of the comprehensive consideration of lamps and lanterns. 
LED is made of nontoxic materials,  unlike fluorescent lamps containing mercury pollution, while LED can also be recycled, belongs to the typical green lighting source.

Lagrange method is applicable to solid, ALE method is suitable for multi-material fluid, SPH method applies to high-speed collision and deformation of material.
Backfill material was dry sand.
The ALE method requires building explosives and air, explosives, soil and air compose ALE multi-material group, with fluid-structure interaction method to calculate the interaction between fluid and the structure.

The Hockett–Sherby hardening law is modified by associating with strain rate dependency similar to Wagoner: , (2) where a, b, c, d and m are temperature-dependent material parameters.
As could be established if plastic deformation occurs [9], the Peric model is rewritten: , (3) where material parameters and m are temperature dependent.

The materials and the energy consumed in each phase have to be monitored, collected and quantified.
That means tracking materials through life."
Such method is suggested when the environmental impact of metallic materials has to be quantified [15, 16].
Further developments of the present study will concern the analysis of case studies characterized by different component shapes (with different amount of removed material), and by different materials.
