    BIM技术在Venlo温室设计中的应用分析

    Application of BIM technology in Venlo greenhouse design

    • 摘要: 针对现行大型温室设计过程中普遍存在的设计工作流中信息不连贯、多平台重复建模、修改图纸工作量大且易出错以及预算工程量主要依靠人工提取等问题,提出一种基于BIM(Building Information Modeling)技术的大型温室设计方法和工作流。依托BIM技术在建筑领域的应用,有机结合高科技温室的设计工作需求,以Venlo温室为例,研究了设计阶段应用BIM技术的系统方法,明确了不同功能软件之间的信息交互模式,构建了基于BIM技术,以Revit为核心的Venlo温室设计、分析、出图和造价分析全体系工作流程,创建了基于中国温室技术特点的Venlo温室BIM族库。实现了从场地形体方案筛选、主体模型搭建、流场分析、结构分析、节点深化、各系统安装及综合检查、图纸明细表生成和效果图制作等全流程的BIM工作流体系搭建。研究结果表明,尽管BIM设计方法需在模型创建阶段投入相对较多时间,但分析工作可以基于BIM模型快速流畅进行,图纸可以借助软件在碰撞检查后快速创建,特别是在设计优化时可以快速地完成图纸的系统修改和完善,显著减少了重复绘图时间工作量,整体上可以较现行设计方法设计效率提升30%。将BIM技术应用在Venlo温室设计中,可以优化设计流程,加强对项目信息的管理和应用,提高项目设计效率和效益,对设施园艺产业的高质量发展有积极意义。

       

      Abstract: Abstract: The current design of the greenhouse cannot fully meet the high requirement of modern agriculture in recent years. It is necessary to deal with incoherent information, repetitive modelling, frequent revision of drawings, and manual extraction of variables during the design process. In this study, a Building Information Modeling (BIM) approach was proposed to the design of Venlo greenhouses. The design process consisted of schematic design, model creation, and design output. Before that, some specific configuration needed to be done. A systematic approach was established to apply the BIM technology for the Venlo greenhouse at different stages of the design process. Special software was then selected to create the greenhouse BIM. A BIM-based workflow was also constructed for the design, analysis, drafting, and material statistics of the glass greenhouse. Furthermore, a family library of the parametric component was created to screen different templates, according to the characteristics of Venlo greenhouse components. Subsequently, the site was arranged using the Revit's topography and volume modules in the schematic design. A visual analysis of climate data in the site was carried out using Ladybug Tools. The hours of direct sunlight on the winter solstice were also compared to determine the direction of the greenhouse. Additionally, the operator was created in Grasshopper to process the meteorological and the geometric data of greenhouse, in order to calculate the cooling and heating loads, as well as the maximum ventilation of greenhouse, thereby determining the equipment parameters. In the model creation, the elevation and axis networks were created in Revit for the positioning of the structural frame family, according to the defined scheme. A structural model was automatically generated and then exported to the Dlubal RFEM interface for the displacement and strength verification, where the specification of the frame was adjusted in real time. Afterwards, the components were deepened with the open cuts from the Revit family module, the steel module, and Advance Steel. The rest of the production systems were also created in turn after the structural framework, such as the enclosure, natural ventilation, and irrigation system. Moreover, a comprehensive evaluation of the model and systems were coordinated in Navisworks, according to the generated reports of collision detection. In the design output stage, the drawings were created quickly, where the comments were added in the views, further to drag into the title bar. The simple components were generated from the component view and complex assemblies, such that the trusses were created with Advance Steel. Material statistics were also completed separately using a family category. As such, the model was imported into the Lumion for rendering and animation using a plug-in. Anyway, the smart BIM model of the greenhouse was then created, together with a visual display of component installation. The BIM technology can be expected to break through the design chain. Specifically, the multiple uses of one model, simultaneous analysis, and automatic bill of materials statistics can greatly reduce the workload of drawing changes, and save one-third of the time, compared with the conventional. Consequently, the design process of Venlo greenhouse can be optimized to facilitate communication among multiple parties, while strengthening the management and application of project information, particularly for higher efficiency of project construction. The finding can also offer a new design approach to the greenhouse installation.
