Abstract
Windows generally have the lowest temperature index in current building types, and will consequently be the primary location for interior surface condensation. Surface temperatures can easily be calculated using thermal finite-element-models, but these generally omit the effect of convection in the windows and the window-wall interface. Hence, there is a need to determine if specific interface details provide potential for condensation on the window components in which air leakage paths may be prominent. The paper reports on a laboratory evaluation of condensation risk assessment in a hotbox, with varying pressure differences and the introduction of deficiencies. It was concluded that the effect of the type of insulation in the window-wall interface was very low for isobaric boundary conditions, whereas it has a significant effect when pressure differences are applied.
