Abstract
In view of the shortcomings of the traditional architectural design mode, such as high rework rate in the construction process and lack of collaborative design and intelligent information processing, a green building energy-saving design method based on BIM technology was proposed. Based on the comparative analysis of traditional computer-aided building design and BIM green building technology, the overall scheme of energy-saving design was constructed from the aspects of green building design principle, design preparation, and design concept. This paper expounded the connotation of energy-saving design elements from the aspects of modeling software selection, envelope energy-saving design, and lighting energy-saving design. Accordingly, the characteristics and process of building energy efficiency analysis based on BIM were proposed. Finally, the energy-saving effect evaluation method of green building based on BIM was given, and an example showed that the energy-saving design method of green building based on BIM proposed in this paper had good feasibility and effectiveness. The method proposed in this paper can provide a certain theoretical basis and application support for the application of BIM technology in the field of green building.
Highlights
Since the end of the last century, most developed countries have been deeply exploring green buildings and their applications and have successively issued some different evaluation standards based on the reality of various countries, which has accelerated the development of green buildings in the world to a great extent [1,2,3]
There were many problems in building energy consumption analysis due to the limitation of technical conditions. e traditional building energy consumption analysis is mainly carried out in the construction process. e architectural design drawing cannot be changed, even if the problems found through energy consumption analysis cannot be reworked, resulting in a waste of human and material resources. erefore, using the building model to analyze the energy consumption in the design stage and obtain the optimal design scheme can effectively improve the later construction efficiency and reduce the construction cost. e traditional energy consumption analysis method usually only analyzes a single factor without comprehensively considering the influence relationship between relevant factors, which makes this energy-saving scheme lack economy and practicability
BIM technology is applied to process and analyze the data, the built building model is used to integrate and analyze the relevant information, external environment, and required parameters, and the building energy consumption is simulated and analyzed by running relevant programs. e building model based on BIM technology can realize the interaction between modeling software and energy consumption simulation software
Summary
Since the end of the last century, most developed countries have been deeply exploring green buildings and their applications and have successively issued some different evaluation standards based on the reality of various countries, which has accelerated the development of green buildings in the world to a great extent [1,2,3]. With the continuous development of green building field, BIM technology has been widely used in western developed countries. With the promotion of BIM software, such as Revit series of Autodesk company and ArchiCAD of graph iSOFT company, it has been well applied in the field of green building [4, 5]. Applying BIM technology to the design of construction projects can predict and find the deficiencies in the design and avoid the additional consumption in the actual construction process [6,7,8]. The effective integration of building a 3D model and structural model with the Revit structure can promote the information exchange and collaborative work of construction project participants
