Geo-climatic applicability of sunspaces in European climates including resilience to climate changes

The paper will implement a methodology to assess the local geo-climatic applicability of sunspaces in European climates considering both winter and cooling seasons. The proposed method is based on the development of a key performance indicator (KPI) able to define the potentiality of sunspaces in reducing the winter energy demand of buildings according to the local climate conditions. Furthermore, a second KPI will be introduce to include in the analysis the negative effect of sunspaces in the summer season considering the positive effect of shading systems and natural ventilation for preventing and dissipating the overheating effect of this technique. The proposed KPIs will be calibrated using two technological configurations of a sample residential building unit considering different levels of performance of the building envelope (high insulated envelope and low insulated one). ?alibration and analyses will be based on the use of virtual-climate related energy demand indexes (heating and cooling degree days) and on the parametrization of results of a large number of dynamic energy simulations performed on the sample building unit using EnergyPlus. Finally, effects of climate changes are considered including typical weather morphing in accordance to IP?? scenarios. This last analysis will help in introducing a resilience-based calibration of the previous defined KPIs facing climate change impacts
