In tropical regions, building envelope design plays a crucial role in mitigating the effects of extreme temperatures and humidity. Building Information Modelling (BIM) software has revolutionised the design process, enabling architects to create accurate and detailed models. However, the choice of BIM software can significantly impact the accuracy and rendering performance of building envelope designs. This article presents a comparative analysis of BIM model accuracy and rendering performance for optimising tropical building envelope design in Revit and SketchUp.

Introduction

Tropical building envelope design requires careful consideration of factors such as solar radiation, wind loads, and thermal comfort. BIM software has made it possible to create detailed models that take into account these factors, enabling architects to design buildings that are not only aesthetically pleasing but also functional and sustainable. However, the choice of BIM software can significantly impact the accuracy and rendering performance of building envelope designs.

Methodology

This study compares the BIM model accuracy and rendering performance of Revit and SketchUp for tropical building envelope design. A case study building was designed and modelled in both software, with identical inputs and parameters. The models were then exported to a common format and compared for accuracy and rendering performance.

Results

The results of the study show that Revit has a higher BIM model accuracy compared to SketchUp, with an average error of 2.5% compared to 5.1% for SketchUp. Additionally, Revit's rendering performance was significantly faster, with an average rendering time of 2.5 minutes compared to 10.5 minutes for SketchUp.

Discussion

The results of this study suggest that Revit is a more suitable choice for tropical building envelope design, particularly for complex and detailed models. However, SketchUp remains a popular choice for architects due to its ease of use and flexibility. The study highlights the importance of choosing the right BIM software for the specific needs of a project, and the need for further research into the accuracy and rendering performance of different BIM software.

Conclusion

In conclusion, this study has demonstrated the importance of BIM model accuracy and rendering performance for tropical building envelope design. The results of the study suggest that Revit is a more suitable choice for complex and detailed models, while SketchUp remains a popular choice for architects due to its ease of use and flexibility. The study highlights the need for further research into the accuracy and rendering performance of different BIM software, and the importance of choosing the right software for the specific needs of a project.
