A Modelling Method To Assess The Effect Of Tree Shading For Building Performance Simulation

Anthony Dawkins, Dominique Hes, Lu Aye

Abstract: Increasing urban tree numbers is a simple but effective means to provide climate change adaptation to the urban environment by reducing the thermal load on buildings. To better communicate and value the importance of urban trees it is necessary to quantify these benefits and to understand the properties and processes that influence the magnitude of these benefits. For this we need verified and effective ways of modelling the trees in modelling software. This paper presents the results and problems encountered when trying to model trees effectively. The aim is to present our approach which was to treat the shade as a shading co-efficient on the wall. This allows for the consideration of the benefits of deciduous versus evergreen species. A modelling method to assess the effect of tree shading was developed and presented in this paper. Key words: thermal simulation, solar thermal load, modelling of tree shading
