摘要:传统的2D CAD技术在对建筑进行描述的过程中，由于建筑的平面和立面以及详图都是分开设计，不仅仅耗费时间，而且常常出现错误，难以将建筑形态加以详细准确描述，同时，由于CAD本身的局限性，设计师很难对二维空间模型做出准确的建筑性能分析。BIM技术的出现使设计师从二维平面拓展到三维空间，并且通过信息模型能准确的进行建筑性能分析。本文以三亚新海干部疗养基地为例，阐述了BIM技术在该项目设计过程中的应用，同时重点研究BIM技术和其他建筑性能分析软件的协同对接过程，归纳了一系列对可持续建筑设计具有指导意义的设计流程。

Abstract: The traditional 2D CAD technology in the process of the architecture description, because the building plane, elevation and detailing are designed separately, not only wastes time, but also makes the mistakes frequently. It is difficult to describe the architecture in detail accurately, while due to the limitations of CAD, the designer is hard to make accurate building performance analysis of the two-dimensional space model. The designers can expand from the two-dimensional plane to three-dimensional space in designing as the appearance of BIM technology, and analyze the building performance accurately in the information model. This article gives an example as Sanya Xinhai Cadre Sanatorium, it states that BIM technology was used in the project design, at the same time, focusing on the study of BIM technology collaborates docking process with other building performance analysis software, summed up a series of design process which has guiding significance for the sustainable architecture design.
