Abstract: Application of insulation to existing facades can improve buildings' energy performance and reduce condensation risk. However, in case of historical buildings, the preservation of the façade's appearance represents a constraint regarding the choice of insulation method. In such cases, aerogel-based plaster may provide a solution. In this context, the present study investigated the effect of aerogel plaster position and thickness on the hygro-thermal performance of residential buildings using a simulation model. The results suggest that, with regard to the surface condensation risk, the position of aerogel plaster (outside versus inside) – but not so much its thickness – significantly influences the risk of condensation.
