Risk management of windows performance

Abstract

Glazed windows have a long history and good practice has been established. Nevertheless, failures still occur. This is usually the case when the systemic approach to the design change was not adopted. Risk management technique based on systemic approach is proposed as a tool supporting the choice of design/retrofitting strategy. The failures concerning windows are categorized. Many problems encountered today with windows are related to the destructive action of moisture. The qualitative and quantitative approach to system failure based on risk analysis theory is described and the examples concerning condensation on glaze pane of windows are provided.
