Evaluation of building energy use: from the urban to the building scale

A 1-D canopy interface model (CIM) has been developed recently and integrated in the meso-scale meteorological WRF v3.5 model in order to improve the surface representation. One of the objectives of such a model is to prepare for the coupling of micro-scale models with meso-scale models so as to improve building energy consumption estimates at the urban scale as well as improve meteorological variables calculation in urban canyons. The objective of the present study is to evaluate the value of the use of a module able to produce highly resolved vertical profiles of these variables. We will discuss the strategy that will be used to couple the WRF system with the CitySim software. The one-way coupling methodology for the WRF-CIM-CitySim is detailed here. It is expected that the WRF-CIM system can provide enhanced meteorological profiles to CitySim and that this can hence improve the energy consumption calculation at the building scale. This coupled system, could be used by urban planners or architects, as it would provide a significant advantage in the evaluation of building energy use and urban planning scenarios. Future work will focus on a two-way coupling in order to improve the feedback response in the meteorological model.
