For enhancing energy-saving for construction engineering project, energy-saving oriented matrix management mode (ESOMMM) is proposed. The frame of the ESOMMM in engineering project is established from two dimensions (basic stage and key content). Under the precondition that the key contents are implemented, the key energy-saving techniques are respectively studied from planning, building, rebuilding and usage stage. And the coordination optimization model for key techniques under ESOMMM is established to solve conflict among varied key techniques. The energy-saving achievement after application is analyzed by applying ESOMMM, its key techniques, and the coordination optimization model in Shenyang city. The result shows that above mode, key techniques and model in engineering project will be benefit for enhancing the energy-saving greatly.

The blank’s dimensions are an important focus of blank design as they largely determine the energy consumption and cost of manufacturing and further processing the blank. To achieve energy saving and low cost during the optimization of blank dimensions design, we established energy consumption and cost objectives in the manufacturing and further processing of blanks by optimizing the parameters. As objectives, we selected the blank’s production and further processing parameters as optimization variables to minimize energy consumption and cost, then set up a multi-objective optimization model. The optimal blank dimension was back calculated using the parameters of the minimum processing energy consumption and minimum cost state, and the model was optimized using the non-dominated genetic algorithm-II (NSGA-II). The effect of designing blank dimension in saving energy and costs is obvious compared with the existing methods.

BIM technology is the hot issues on construction engineering project development and application in and abroad currently. BIM technology had been widely developed in foreign countries after the Americans brought up the BIM concept in the 1970s. They had got good results in the actual application as well as many valuable achievements and experience. We focused on the present situation and application of BIM technology from the international view, and then we summarized the trend of the studies on the application of BIM technology in foreign countries. We have tried to provide a new revelation on construction projects of BIM technology in our country by the comprehensive cognition. They got the thought of experiences and the application train.

And Control

As a new energy-saving and environmental protection building material, dry-mixed mortar has been promoting actively in China. The key techniques of control system for dry-mixed mortar production line were introduced in this paper, which was mainly based on PLC and smart weighing instrumentation. Firstly, the technology process and control demands were presented. Secondly, control system configuration, control strategy were proposed in detail. Finally, the key intelligent adjust algorithms were described as well. The practical operation verifies that the control system is highly reliable and stable, and it greatly enhances the level of automation and weighing accuracy of the raw material and meets the equipments requirements of energy-saving and green running.
