A detailed study of the different turbulent fluxes in an urban environment considering a Building Energy Model coupled with an Urban Canopy Parameterization (one dimension off-line simulations)

Recent studies show that the fluxes exchanged between buildings and the atmosphere play an important role in the urban climate. These fluxes are taken into account in mesoscale models considering new and more complex Urban Canopy Parameterizations (UCP). In this work, an UCP with and without a Building Energy Model (BEM) is run 1D off-line and the results are compared against the experimental data obtained in the BUBBLE measuring campaign over Basel (Switzerland) in 2002. BEM computes the evolution of the indoor building temperature and the impact of the air conditioning (AC) systems. This evaluation exercise is particularly significant, since for the period simulated, indoor temperatures were recorded showing that the AC systems were working. Different statistical parameters have been calculated over the entire simulated episode in order to compare the two versions of the UCP against measurements. Moreover, the impact of the AC systems and their energy consumption are evaluated in different situations .
