Abstract
To improve the prediction of the building’s energy performance, it has become necessary to evaluate their interactions with the urban microclimate. This study aims to propose an integrated model in the TRNSYS software with a simplified approach to assess building energy demand, including microclimate interactions on buildings. This model is based on thermoradiative and aeraulic modelling by considering the moisture transfer through the envelope. To evaluate the validity of this method, an urban canyon was modelled and compared with existing experimental results. The numerical results are close to the experimental observations with a mean absolute error of about 1°C for the outside surface temperature and a mean relative error of approximately 5%. The developed model has shown its potential in reducing an unexpected impact of interoperability when using several tools and to ensure shorter computation time compared to CFD calculations, with an accuracy satisfying the thermal and energy evaluation objectives.
