Abstract

This report presents sensitivity study of thermal and comfort performance of triple glazing with external shutter influenced by parameters including tilt angle of entire window, cavity thickness between glazing unit and shutter, air penetration rate between cavity and outdoor air and position of coating on shutter. Additionally, this study presents sensitivity study of combined daylight level and linear loss of windows, considering properties like installation level of window on roof, insulation around window frame, cutting of lining and thickness of roof insulation layer.
