Retrofitting of building envelopes: Evaluation of effectiveness using weather-affected material parameters
Original language description
Thermal performance of a brick wall after retrofitting is investigated by means of computational modelling of coupled heat and moisture transport. In the first step, temperature and moisture distribution over a reference year (Prague) is estimated, being subsequently used for the calculation of heat transmission through the envelope. Then, the annual energy balance is expressed. The simulations are carried out using both reference material parameters and weather-affected data of the brick. The comparison of results indicates that weathering may have a positive effect on the thermal performance of brick walls as it can contribute to a decrease of annual energy balance by ~ 2%. It means that this change can be considered on the safe side, without a risk of overestimation of thermal insulating capabilities of brick walls after retrofitting. The thermal assessment of several retrofitting alternatives reveals that hydrophobic mineral wool applied on the exterior side presents the most favourable option.
