This deliverable summarizes the current situation of all relevant aspects for the future planning and optimization of the local energy system at the demonstrator site of this Joint Activity (Rolle and Mont-sur-Rolle VD). The two communities are analyzed in terms of settlement structure, buildings, renewable energy potential and waste heat. The analysis of the settlement structure yields areas that will require special attention during planning and implementation of future changes to the local energy system – for environmental, social or technical reasons. Furthermore, it lays out existing structures, like road networks, electrical and gas-grids. The analysis of buildings shows that fossil fuels are the predominantly used source of heating energy in Rolle and Mont-sur-Rolle. Hence there is a large potential for the reduction of greenhouse gas emission. A fast simulation model to calculate time series for heating and electricity demands had been developed. This models allowed us to generate time series for each of the 1650 houses in less than 1 hour. Exemplary results for individual buildings are presented in this deliverable. These models will be an essential component in achieving the next milestones of this Joint Activity and will enable practitioners to use time-resolved demand curves in their planning processes. In the last part of this deliverable, the potential for renewable energy generation is analyzed. Estimations for thermal energy that can be provided by locally available wood, Lake Geneva and geothermal probes, as well as, estimations of the wind energy and PV potential lead us to the conclusion that the current energy demand could be entirely covered using renewable sources. Hence this deliverable prepared the basis for the next steps of developing the energy concept for Rolle and Mont-sur-Rolle.
