Abstract

Abstract There are several outdoor microclimatic simulation software tools in use. The current research aims to identify some of the most prominent computer-based tools based on their capacity of predicting a significant number of variables and compare them in order to establish their differences. This article provides an overview of the applications of computational fluid dynamics in outdoor performance simulation, focused on three topics: general criteria, specific outputs, strategies, and elements can be investigated by the tool. The results have shown that ENVI-met tool is capable of predicting and simulating the set microclimate variables.

Highlights

  • The energy demand of the built environment is almost 50% of the total energy demand of a national economy [1]

  • This paper provides an in-depth study, which compares the features of eight primary microclimatic simulation software tools: Rayman, ENVI-met, ANSYS, Autodesk Computational Fluid Dynamics (CFD), CitySim Pro, TAS, Meteodyn, Honeybee, and Ladybug

  • Strategies and elements can be investigated by the tool in outdoor spaces

Summary

Introduction

The energy demand of the built environment is almost 50% of the total energy demand of a national economy [1]. The scientific community has become interested in how urban design impacts outdoor thermal comfort. Enhancing the health and well-being of citizens, reducing heat and cold stress, and prolonging periods of comfort, are new focuses on design. It is today being investigated how the built environment alters local microclimates by influencing a series of thermodynamic phenomena. Because of the dynamic nature of the urban environment, it is difficult to find a simulation tool that adequately models all of the Unauthenticated | Downloaded 11/02/21 02:43 PM UTC. Considering that in the last five years, researchers and designers have increasingly approached the modeling of microclimates, being aware of the modeling capabilities, and limitations of tools applicability has become critical [2]
