Meteodyn had the pleasure to present its latest research at the 2023 Building Simulation Conference with both a paper and a poster. Our work focused on the integration of Computational Fluid Dynamics (CFD) results with the Grasshopper interface to compute the Universal Thermal Climate Index. You can download the associated paper and the poster using the form below.

The achievement of a net-zero carbon building by 2050 require 50% decrease of CO2 emissions and 60% of energy consumption. The building construction must minimize its impact (energy consumption, pollution...) and existing buildings must find a way to mitigate effect of global warming mostly in city because of the Urban Heat Island (UHI) effect.

CFD (Computational Fluid Dynamics) simulation during the design process or with exisiting building is a key to improve quality and comfort for pedestrian. The thermal comfort is one of the indicators that can help urban planners or achitects to determine human comfort.

Because of interoperability and convenience for non-expert users, nowadays, architects use more and more plugins integrated in their CAD software. However, CFD software usually require high computer resources during installation and a long computation time, which may not meet the requirement for obtaining fast feedback results in time-critical designs. One of the main challenge is then to make CFD simulations easy to understand and perform.

We complete this overview by providing another workflow to compute Universal Thermal Climate Index (UTCI) using Grasshopper, a visual programming language and environment integrated in CAD software Rhinoceros, and CFD result computed by UrbaWind software, dedicated to urban area since 2007.
