A parametric design method for CFD-supported wind-driven ventilation

Abstract

The negative impact of the building industry has brought a critical emphasis on the performance-related tools and processes of architectural design. The integration of design and performance simulation has the potential to extend the decision-making capabilities of the architects. Amongst a number of performance parameters, wind-related measures are generally problematic for the design phase, due to the computational cost of predicting wind behaviour, the complexity of the urban context and the constantly changing airflow patterns. In this respect, this paper proposes the preliminary exploration of a design method towards integrating Computational Fluid Dynamics (CFD) coupled with energy modelling and parametric design tools for the wind-related design acts. As building performance is regarded as a design problem that necessitates a designerly point of view as much as a technical perspective, the method aims at providing visual, generative and accurate feedback regarding its potential to facilitate the architect’s designerly integration to the process and to provide a flexible design environment. The preliminary quantitative analysis conducted through a case study indicates the preliminary data flow through the design process.

Towards Achieving Sustainable Development Goal-2030 Agenda-Thirteen: A Review of Technological Advances from the Built Environment Professionals

“…It is used to model and quantify airflow-related cases (including ventilation, infiltration and dispersion of the contaminants), and test the wind-built environment interactions through numerical analysis. It enables the analysis of various shapes and environmental conditions(Lee et al, 2021;Merin Abbas & Gürsel Dino, 2019). It constitutes an important tool to understand current airflow designs, to reveal present shortcomings for improved ventilation and energy performance in particular(Melendez, Reilly & Duran, 2021).…”
