Abstract

The heat generated in buildings and the manner in which this heat is exchanged with the ambient environment can play an important role in urban climate. Recent studies have shown that anthropogenic heat from air-conditioning facilities can increase the exterior ambient temperature and should be taken into account for a more complete urban heat island (UHI) mitigation study. For this purpose, the first part of the present work is focused on the coupling of a new building energy model (BEM) and an urban canopy parameterisation (UCP). The new scheme is implemented in a finite volume mesoscale model (MM) and tested in a two-dimensional (2D) configuration of a city over flat terrain. A sensitivity study is performed with respect to different parameters in order to test the simulation system and enhance the understanding of the possible impacts of the BEM on the exterior microclimate.
