Integrated Vegetation Model For Studying The Cooling Potential Of Trees In Urban Street Canyons, Lento Manickathan, Aytaç Kubilay, Thijs Defraeye, Jonas Allegrini, Dominique Derome, Jan Carmeliet

International Building Physics Conference 2018

Vegetation in cities provides natural cooling of the climate and is therefore increasingly integrated as an essential part of Urban Heat Island (UHI) mitigation strategies. In the present study, the influence of trees on the local climate in a street canyon is studied using an integrated vegetation model in OpenFOAM. Vegetation is modeled as porous medium providing the necessary source terms for the heat, mass and momentum fluxes. Additionally, a radiation model is developed to model the short-wave and long-wave radiative heat flux exchanges between vegetation and the surroundings. The study investigates the influence of transpirative and shaded cooling due …

International Building Physics Conference 2018

Building materials that are commonly used in urban areas generally have higher sensible heat storage and radiation entrapment, while having lower moisture storage and evapotranspiration, in comparison to the materials found in rural areas. These differences play a significant role in the occurrence of the urban heat island (UHI) effect, which has adverse impacts on thermal comfort, energy use and public health. Coupled numerical simulations of computational fluid dynamics (CFD) with the heat and mass transfer (HAM) in porous urban materials are performed to estimate the evaporative-cooling potential of different pavements in a street canyon. The local thermal comfort following …
