Trends in the application of CFD for architectural design
This paper is an overview of the trends in the application of Computational Fluid Dynamics (CFD) in architectural design. This paper aims to identify the current trends of CFD-related research in the architectural field and questions how CFD may interact with architectural design practice. To achieve the research objectives, a thorough literature review was conducted with two steps. First, relevant data were collected from journals and conference proceedings. The collected data were categorized according to the detailed topic of literature, such as designing HVAC and building envelope systems, evaluating indoor climates, simulating outdoor airflow, and developing early-stage designs. Based on the developed categories, we studied the trends of the CFD-related paper submissions for the International Building Performance Simulation Association (IBPSA) international conferences from 1997 to 2015. The results showed that the amount of CFD-related research has been constantly growing due to the increase of case-based research, and because the design process itself (including decision-making) has been an active research topic recently. Through in-depth literature review and trend analysis, we found that CFD-related research has been evolving in interaction with architectural design practice, and that the boundary of the research has expanded from evaluation of built environments to include the early stages of design.
