The comparison between sensitivity analysis and survey results indicates that the influence of window properties on life cycle cost is over estimated by most of the surveyed participants.
The energy effect of window properties, window-to-wall ratio (WWR), building orientation and lighting control strategies have been analyzed, and can be indicated by the localized WERS.
Cost optimal and as energy efficient as possible façade solutions, including window properties, external wall insulation, window-to-wall ratio and external shading were determined with energy and daylight simulations in the cold climate of Estonia.
By means of a regression analysis, simple charts for the relationship between window properties and building energy performance are presented as a function of U-value, SHGC, Tvis, WWR, solar aperture, effective aperture, and orientation.
Interestingly, the sensitivity analyses performed for the medium size DOE Department of Energyy) reference building indicate that wall assemblies have a much larger impact on building life cycle costs than window properties.
While other researchers have proposed modifying congestion window properties to improve TCP performance in an ad hoc environment, the authors of this paper propose using multiple TCP flows per connection.
