随着“十二五”期间我国城镇化、工业化的快速推进，建筑物的能耗已上升到社会总能耗的30%，约60%的节能减排资金都用在建筑节能项目中。因此对通用建模机理与建筑能耗模型的研究意义重大。但由于建筑物的能量表征机理不清楚、建筑环境的复杂时变与多关联性耦合约束性，目前常用多项式耦合近似计算。按照项目指南要求，针对建筑节能领域的重大应用前景，重点探索基于消息云机制的变模态变结构能连网建模机理。本项目以建筑能耗为研究对象，以面向对象的建模机制为主线，以建立精细化、精确化、通用化的建筑能耗模型为目标。首先运用能量守恒原理抽取能量节点对象，其次采用消息云机制下的能连网建模机理进行分析，然后探索变模态变结构的能连网模型，最后提出一套具有普适性的建筑建模机制、技术与方法，为我国建筑能耗领域研究提供理论和技术支撑。

China's urbanization and industrialization process is fast progressing in the 12th Five Year Plan period. However, the building energy consumption is yearly raising, it has already accounted for about society's total energy consumption by 30%, which restricted the healthy development of Chinese society. In addition, there are 60% funds of energy conservation in china that are used in the construction of energy-saving projects. Therefore, it is necessary to make the physical description for the energy consumption of the building, and has great practical significance to establish fine and precise building energy model and study the mechanism of general energy consumption model, which also is the premise to achieve energy-saving. On the other hand, the mechanism of building energy metric isn't yet recognized and has no uniform standards, at the same time multi-factor coupled each other in building complex environment. Currently, polynomial coupled methods are used to build model, but application effect needs further improvement. Our projects base on the field of building energy-saving with significant prospects, focus on object-oriented model based on message cloud mechanism and energy-net energy-saving model with collaborative and optimization. The term object of study is building energy consumption, mainline is object-oriented modeling mechanism, and the goal is to create fine, precise, universal building energy model. Meanwhile the starting point is to extract energy node objects and energy conservation, methods is the message cloud mechanism. Of course, it is important for comprehensive study of the principles of energy net of modeling that explore the mechanism of change modal model variable structure, and propose a mechanism for object-oriented modeling, techniques and methods which can be generally applicable to the construction of energy consumption. The purpose of the research is to provide theoretical and technical support for the field of building energy consumption.
