Optimizing Windowpane Performance in Terms of Solar Radiation and Thermal Conductivity for Balancing Lighting and Thermal Models in Architectural Spaces (original) (raw)

This study optimizes the number of windowpanes in terms of the integrity of daily lighting and heat transfer and solar radiation in architectural spaces. The study tests single pane, double pane, and triple pane windows in terms of solar energy gain and loss by radiation and thermal conductance. Due to high interconnectivity amongst building façade parameters, daylight and heat gain are much affected by the transmittance factors of windowpanes. Accordingly, this study seeks integral formulas that correlate daylight levels and heat gain in spaces. It seeks for the optimal number of window layers that prevent heat loss in winter without reduction in solar radiation or light through windows. The study used Radiance software for lighting analysis to simulate daylighting levels in spaces using single, double, and triple-pane windows. In parallel to daylight performance, the heat conductance of the three cases of windowpanes was compared with the solar transmittance to reach optimal solut...
