Spatial and temporal characterization of energy demand and resources for an existing and dense urban district in Geneva

Abstract This paper focuses on the characterization of the energy demand and the locally available renewable resources for an existing and dense urban district. Objective is setting up an integrated spatio-temporal database, for the evaluation of diverse strategies concerning the integration of renewables in the existing urban fabric. In a first step, the various demands (heating, cooling and electricity) are characterized in terms of annual values and spatial distribution (at building level), by merging of diverse databases containing actual monitored values, in combination with specific models for the completion of missing data, and for split up in terms of the various usages. In a second step, the aggregated demands (at district level) are characterized in terms of hourly dynamic, for a common reference year, by re-scaling of monitored load curves. Similarly, the existing resources (solar, hydro- and aero-thermal) are characterized by way of monitored values, in terms of hourly dynamic (for the same common reference year), as well as spatial distribution (in particular concerning solar irradiation on building roofs and geothermal resources).
