The pinpointing of the most prominent parameters on the energy performance for optimal passive strategies in ecological buildings based on bioclimatic, sensitivity and uncertainty analyses

Abstract

It is important to know how to reduce the gaps between the predictions and the actual energy consumption of buildings. This work aims at reducing this gap through a three-fold analysis: bioclimatic, sensitivity and uncertainty applied to three ecological houses located in France and belonging to different climate zones. The labelling contexts of these houses are Low Consumption Building, High-Energy Performance and Passive House. This will permit to identify the most influential parameters, their contribution to the overall uncertainty and to visualise the variability of the response for these houses. The crossing of the results using this approach permits to reduce discrepancies between the predictions and the actual energy consumption of the houses. This approach of analysis is necessary and a reliable tool to help bioclimatic design and energy optimisation for a building and the thermal comfort of the occupants.
