In over decades, the architectural evaluation system is playing an more important role in the building energy-saving after the implementation and modification of all evaluation systems. Most of current green architectural evaluation systems remain in the level of single building evaluation, so a set of comprehensive and effective green architectural evaluation system is needed. This paper has analyzed the domestic and oversea evaluation systems of the Green Residence, considering regional characteristics, and examined the indicators of the Hot-summer and Warm-winter Region Evaluation System for providing a reference to the development of Chinese regional residence evaluation system. Some suggestions for the development of Chinese green residential evaluation system are provided through analyzing advantages and disadvantages of evaluation systems in guiding the construction of ecological residential. © (2014) Trans Tech Publications, Switzerland.

As a typical type of non-linear viscoelastic-plastic material, the large-stone porous asphalt mixture (LSPM) has very complex physical behaviour. Via connecting a Burgers model to viscoplastic material body in series, the viscoelastic-plastic constitutive equation was obtained. The viscoelastic-plastic constitutive model was then combined with the law of creep damage, which was used to describe the damage variation of the LSPM, to build the viscoelastic-plastic damage constitutive model. This resulting model can simulate the creep deformation behaviour of the LSPM relatively well. Moreover, the uniaxial compression creep tests on the LSPM were conducted in the MTS testing machine, through which the parameters for the viscoelastic-plastic damage constitutive model were determined. Finally, the approximate functions describing the relationships of the parameters versus temperature and stress were constructed.

In this paper, the basic situation of Guangxi luocheng Kama reservoir and the potential dangers are introduced firstly, and then, different models often used to estimate the loss of life in dam failure at home and abroad are introduced and analysed.Based on the above, a suitable model for national actual situation is chosen to predict the loss due to this reservoir dam breach, and the severity according to the calculation result of assuming Kama reservoir dam-break is assessed. Finally, the relevant departments's measures of rescuing and evacuating downstream masses etc. at danger in 2009 are proved to be correct, necessary and timely. © (2011) Trans Tech Publications.

This paper presents a numerical simulation method for analyzing the thermal improving effect of urban surfaces (pavement and building surfaces) with evaporative cooling effect on the urban built environment. The numerical models for simulating the cooling effects of these cooling surfaces were proposed after analyzing the experimental data. The surface wet condition of the moist pavement can be modeled as a function of the pavement water content. The cool building surface is coated with photocatalyst (TiO2) and sprinkled with water in order to cool external surfaces of the building. During sprinkling, the wetted building surface can be modeled to be covered with a free water surface because the TiO2-coated surface can be completely covered with a thin film of water. The simulation algorithms for the two cooling strategies were integrated into a 3D-CAD-based thermal simulation tool. The simulated surface temperature agrees well with the measured result for the cool pavement. As a case study, the cooling effects of these cooling strategies applied to an urban area were simulated and quantified in terms of surface temperature reduction, mean radiant temperature (MRT) and heat island potential (HIP). As a result, the thermal improving effect can be visualized on 3D-CAD models for the analyzed urban block. © 2012 Elsevier Ltd. All rights reserved.
