摘 要

BIM是以三维数字技术为基础集成了建筑工程项目各种相关信息的工程数据模型,在现代建筑行业中运用十分广泛。随着经济发展,建筑能耗增加,建筑节能是国家节约能源战略的重要环节,通过BIM相关软件实现设计阶段建筑能耗的预测并进行调整控制,是一种简便有效的方式。

随着绿色建筑的发展,建筑的日照节能变得十分重要,而BIM在节能日照方面的运用比较方便直观,也能从三维视图中了解建筑物的日照因素的变化,能便捷地分析其日照情况。BIM运用3D模型对建筑物进行模拟,在设计阶段就可以分析建成后的日照情况,将结果具象化,可以在设计阶段了解到后面会遇到的问题,提高了设计效率,减少返工。

本课题是对汤山碧桂园的一幢别墅进行日照节能分析,其主要研究思路为:Revit建立三维模型—Green Building Studio模型日光研究—Ecotect建立日照模型—Ecotect模型节能分析。

通过运用BIM相关软件,结合BIM理论知识可以了解建筑物外围结构的光照情况,明确知道外立面每个点的日照时长。通过碧桂园别墅的实例分析提出项目的节能方案,提高了社会效益和经济效益。

BIM-Based Energy Saving Design of Civil Buildings in Southeast University

Abstract

BIM is based on the three-dimensional digital technology and integrated with engineering project data models of various of information. Along with the development of economy, building energy consumption is increasing. Building energy efficiency is an important part of the national energy saving strategy. It is a simple and effective way to adjust the design phase of building energy with BIM softwares.

With the development of green building, energy saving and sunshine are more important. BIM is more convenient and intuitive. We can also see the consumption of the buildings and the changes of the sunshine factors from the 3D modeling and analyse them easily. BIM simulate the building by 3D modeling. During the design phase, BIM can analyze the sunshine situation of the building after construction, and concrete results, solve problems, improve efficiency and reduce rework.

The project is about the analysis of energy saving and sunshine of BiGuiYuan in Tangsha, Jurong, Nanjing. The research idea is that Revit modeling, Revit simulates daylight research, Ecotect modeling, Ecotect sunshine analysis, Green Building Studio sunshine analysis and sunshine analysis report. Then the Civil Building can be simulate in a video that the shadow changes under the sun during a day. The sunshine analysis report can show some graphs and analyze the sunshine situation quantitatively.

The sunshine situation and duration can be shown by BIM softwares with corresponding knowledge. It can improve the economic benefit and social benefit by proposing the energy-saving project according to the example of the Civil Building.

KEY WORDS: BIM; 3D modeling; sunshine analysis; energy saving
