【摘要】：保障房建筑是以政府为主导的国家安居工程。随着保障房建设规模的逐渐扩大，“工业化”将成为国家积极推行保障房的主要建造形式。国家对保障房的支持力度使其机遇与挑战并存，建筑能耗、环境影响及资源利用是实现保障房建筑“绿色化”的关键。但在具体的实践应用过程中，工业化建筑的设计方法、太阳能设备与绿色建筑技术集成应用等方面仍存在很多问题，特别是针对严寒地区规模化保障房的绿色建筑技术应用的研究仍处以空白状态。基于以上问题，本文从保障房的建设特征、围护部品节能设计与绿色建筑技术集成三个方面入手，对适宜于严寒地区保障房的工业化建筑体系、围护结构的主被动节能设计及围护部品的集成设计平台进行深入研究，提出基于BIM建筑信息技术的围护结构主被动节能技术并进行整合、优化、量化及可行性分析。首先，从我国国情、气候适宜性、技术成熟度等角度对工业化建筑体系进行分析对比，提出预制装配整体式钢筋混凝土剪力墙体系是适宜于严寒地区保障房的工业化建筑体系。从建筑设计集成、结构设计集成、设备系统集成三个层面对该体系的集成设计因素进行分析，提出该体系与绿色建筑技术的集成设计方法。其次，选取严寒地区28个保障房实例及图纸进行调研，，对围护结构节能相关影响因素（体系系数、平面形状、窗墙面积比、墙体构造等设计参数）进行分析，建立了严寒地区保障房建筑的基础模型，为进一步研究围护结构从被动节能到主动产能的集成设计研究提供了有力的支撑与探究的基础。再次，从围护结构被动节能的角度，选取六种典型的工业化复合墙体，运用Designbuilder能耗分析软件对不同复合墙体的年采暖能耗进行对比，从节能的角度提出混凝土空气间层复合墙体为严寒地区保障房适宜的围护结构构造形式。然后，从围护结构主动产能的角度，对太阳能设备与建筑的节点设计、美学设计及技术设计等进行分析研究。运用PVSYST发电量模拟软件对太阳能光伏设备在不同安装环境下的系统年发电潜力进行计算，确立了（以沈阳为例）1kWp光伏系统的节能贡献率；运用光热计算模型对太阳能热利用潜力进行研究，确立了光热系统的节能贡献率。该研究为今后建筑师在太阳能设备应用的规模控制、安装位置与形式的确定等环节提供设计参考。最后，运用BIM建筑信息技术对围护结构的主被动节能技术进行整合与优化设计，在此基础上对围护结构集成设计进行定性与定量化的分析研究，初步验证了BIM建筑信息技术与工业化建筑集成设计平台的可行性，为今后工业化建筑的能源规划与绿色建筑技术的应用提供便捷的工具与科学的应用方法。
[Abstract]:Indemnificatory apartment building is a government-led national housing project. With the gradual expansion of indemnificatory apartment construction scale, industrialization will become the main construction form of actively promoting indemnificatory apartment in our country. The national support for indemnificatory apartment makes it co-exist opportunities and challenges. Building energy consumption, environmental impact and resource utilization are the key to realize "green" of indemnificatory apartment architecture. However, in the process of practical application, there are still many problems in the design method of industrial building, the integrated application of solar energy equipment and green building technology, etc. Especially, the research on the application of green building technology to scale indemnificatory apartment in cold area is still blank. Based on the above problems, this paper starts with the construction characteristics of indemnificatory apartment, energy saving design of envelop and integration of green building technology, and analyzes the industrial building system suitable for indemnificatory apartment in severe cold area. The active and passive energy saving design of the envelope structure and the integrated design platform of the enclosure parts are studied in depth. The active and passive energy saving technology of the envelope structure based on BIM building information technology is put forward and integrated, optimized, quantified and feasibility analysis is carried out. Firstly, from the point of view of our country's national conditions, climate suitability and technological maturity, this paper analyzes and compares the industrial building systems, and puts forward that the precast assembly integral reinforced concrete shear wall system is an industrial building system suitable for indemnificatory apartment in severe cold regions. The integrated design factors of this system are analyzed from three aspects of architectural design integration, structural design integration and equipment system integration, and the integrated design method between the system and green building technology is put forward. Secondly, 28 examples and drawings of indemnificatory apartment in severe cold area are selected to analyze the factors (system coefficient, plane shape, window / wall area ratio, wall construction and other design parameters) related to the energy saving of enclosure structure, such as system coefficient, plane shape, area ratio of window to wall, wall construction and so on. The basic model of indemnificatory apartment building in severe cold area is established, which provides a strong foundation for further research on the integrated design of envelope structure from passive energy saving to active production capacity. Thirdly, from the angle of passive energy saving of envelope structure, six typical industrial composite walls are selected, and the annual heating energy consumption of different composite walls is compared by using Designbuilder energy consumption analysis software. From the point of view of energy saving, it is suggested that the composite wall of concrete air interlayer is a suitable enclosing structure form of indemnificatory apartment in severe cold area. Then, the node design, aesthetic design and technical design of solar energy equipment and architecture are analyzed and studied from the angle of active capacity of enclosure structure. The annual generation potential of solar photovoltaic equipment under different installation environments is calculated by using PVSYST simulation software. (taking Shenyang as an example, the contribution rate of energy saving of 1 kWp photovoltaic system is established. The solar energy utilization potential is studied by using the photothermal calculation model, and the contribution rate of solar energy saving is established. This study provides a design reference for architects in the future application of solar energy equipment in the aspects of scale control, installation position and form determination. Finally, the BIM building information technology is used to integrate and optimize the active and passive energy saving technology of the envelope structure. On this basis, the qualitative and quantitative analysis and research on the integrated design of the envelope structure are carried out. The feasibility of integrated design platform of BIM building information technology and industrial building is preliminarily verified, which provides convenient tools and scientific application methods for energy planning and green building technology application of industrial building in the future.
